Major League Baseball

 * Baseball Hall of Fame Honors

January

 * January 3 – Veteran shortstop Troy Tulowitzki signed a one-year contract with the New York Yankees after missing the entire 2018 season due to bone spurs. The Yankees will pay Tulowitzki the major league minimum salary for 2019 ($555,000), and the contract includes a no-trade clause. For the Yankees, Tulowitzki offered a lost-cost solution to their hole at shortstop, as Didi Gregorius will miss at least the first part of 2019 while he rehabs from Tommy John Surgery.
 * January 11 – The Boston Red Sox and American League MVP Mookie Betts settled on a one-year deal worth $20 million. The salary figure is a record for a player in his second year of arbitration eligibility, with Betts still having one more year of arbitration-eligibility to go. Betts won his arbitration case with the Red Sox a year ago, securing $10.5 million, and will become an unrestricted free agent in 2021.
 * January 15 – Longtime Pittsburgh Pirates broadcaster and former pitcher Steve Blass announced that he would be retiring following the 2019 season, his 60th with the Pirates organization. Blass, 76, was signed as a player in 1960. He spent his entire ten-year career in the majors with the team. His most productive season came 1n 1972, when he posted a 19–8 record with a 2.49 ERA, 12 complete games and five shutouts, while earning an All Star berth and finishing as the runner-up in NL Cy Young voting. In addition, he pitched two complete games victories for the Pirates in Games 3 and 7 of the 1971 World Series triumph over the Baltimore Orioles. Afterwards, Blass joined the team's broadcast crew in 1983. Since 2005, he worked Pirates home games and select road trips, and the 2019 season will be his club-record 34th year as a color analyst for the organization.
 * January 21 – The Cincinnati Reds acquire veteran starting pitcher Sonny Gray from the New York Yankees, which was followed by signing him to a three-year extension of $30,500,000 that includes a $12 million club option for 2023. Reiver Sanmartin, a minor league pitcher, also came to Cincinnati along with prospect second baseman Shed Long winding up in Seattle after being traded by the Yankees. New York also received an undisclosed draft pick.
 * January 22 – For the second consecutive year, the Baseball Writers' Association of America elects four players into the Hall of Fame, including the first player ever selected unanimously, Mariano Rivera, Major League Baseball's all-time saves leader, who was listed on all 425 ballots cast. Rivera is joined by Roy Halladay and Edgar Martínez, both of whom receive 363 votes (85.4%), and Mike Mussina, who receives 326 votes (76.7%). Rivera and Halladay are both elected in their first year on the ballot, while Mussina is elected in his sixth year and Martínez in his tenth and last. Halladay, who died in a plane crash in November 2017, also becomes the first player to be elected posthumously by the BBWAA since Roberto Clemente in 1973. Also in his final year of eligibility, Fred McGriff was unable to receive enough votes to be elected in to Cooperstown by the BBWAA.
 * January 26 – The Los Angeles Dodgers signed free agent center fielder A. J. Pollock a four-year, $55 million deal, plus a $10 million player option for a fifth year. If Pollock declines that option, the Dodgers must buy out his fifth year for $5 million.

February

 * February 8 :
 * MLB commissioner Rob Manfred indicated at the annual owners' meeting that the league is not open to the introduction of the designated hitter rule to the National League. It emerged recently that MLB and the MLB Players Association were exchanging proposals on a variety of significant potential rules changes before the upcoming season. Some of those, including the introduction of a twenty-second pitch clock and a rule requiring any pitcher that enters a game to face at least three hitters, were set forth by the league.
 * The Philadelphia Phillies acquired All-Star catcher J. T. Realmuto in a four-player transaction with the Miami Marlins. In exchange, the Marlins received right-handed pitcher Sixto Sánchez, catcher Jorge Alfaro, lefty-handed pitching prospect Will Stewart and international bonus slot money.
 * February 18 – San Francisco Giants manager Bruce Bochy announced that the 2019 season would be his last. Bochy is ranked 11th in all-time managerial wins with 1,926 career victories.
 * February 22 – The San Diego Padres announced the signing of free agent Manny Machado. The 10-year deal will pay Machado $30 million annually through the 2028 season, and contain a six-team no-trade clause. He will play at third base for San Diego.
 * February 26 – The Colorado Rockies and third baseman Nolan Arenado agreed to an eight-year, $260 million contract with an opt-out in three years. A four-time All-Star and six-time Gold Glove Award winner, Arenado will receive the highest annual salary of $32.5 million, surpassing the $31 million of Detroit Tigers designated hitter Miguel Cabrera, and behind the top earner in Major League Baseball, Arizona Diamondbacks pitcher Zack Greinke, at $34.4 million, for the largest in MLB history.

March

 * March 2 – The Philadelphia Phillies reached an agreement to sign free agent outfielder Bryce Harper to a 13-year, $330 million contract. Harper will receive a $10 million salary and a $20 million signing bonus for the upcoming season. He will then be paid $26 million annually from 2020 through 2028 and $22 million annually from 2029 to 2031. In addition, Harper received full no-trade rights and does not possess any opt-out opportunities. It now stands as the largest fully guaranteed contract in the history of North American team sports, surpassing the 10-year, $300 million contract that Manny Machado signed with the San Diego Padres just the previous week, as well as the 13-year, $325 million deal that Giancarlo Stanton signed with the Miami Marlins in 2014. Mexican boxer Canelo Álvarez signed an 11-fight contract worth $365 million in 2018, but the contract is not guaranteed.
 * March 9 – In a 5–2 victory over Virginia Tech in the second game of a doubleheader, Mike Martin became the all-time winningest baseball coach in Florida State history with his 2,000th career win and the first ever coach to reach the 2,000 win mark.
 * March 14 – Major League Baseball and the Major League Baseball Players Association announced an agreement on significant changes to MLB roster rules that will take effect in 2020. Specifically:
 * Active rosters, currently limited to 25 players prior to September 1 (with very limited exceptions), will increase to 26 players.
 * The "expanded roster", which takes effect on September 1 of each season, will be reduced from 40 to 28 players. Additionally, all teams will be required to carry 28 active players for regular-season games on or after September 1.
 * Players will be specifically designated as "pitchers" or "position players" before each season, with this designation being fixed throughout the season. From 2020, only players designated as "pitchers" can pitch in any regular-season or postseason game, with the following exceptions:
 * One team is ahead by at least 6 runs when the player assumes a pitching role.
 * The game is in extra innings.
 * The player assuming the pitching role has qualified as a "two-way player". A player qualifies as such if, in the current or immediately previous season, he has (1) pitched at least 20 MLB innings and (2) played at least 20 games as a position player or designated hitter, with at least three plate appearances in each game counting toward the latter limit. No player in the 2019 MLB season has yet qualified as a "two-way player" under the new rule. The most prominent two-way player in today's game, Shohei Ohtani, cannot qualify in 2019 because he is not pitching while recovering from Tommy John surgery.
 * A joint MLB/MLBPA committee will make recommendations on limiting the size of pitching staffs that, if approved, will also take effect in 2020. MLB has proposed limiting pitching staffs to 13 through August 31, and 14 from September 1 to the end of the regular season.
 * March 19 – The Los Angeles Angels signed outfielder Mike Trout to a ten-year extension that will pay him $426.5 million through the 2030 season. This represents the largest contract ever in sports history, overtaking boxer Canelo Álvarez, who signed an 11-fight $365 million deal with sports service DAZN in 2018. It is also almost $100 million more than Bryce Harper received on March 2, when he agreed a 13-year, $330 million deal with the Philadelphia Phillies.
 * March 20 – The Seattle Mariners defeated the Oakland Athletics 1–0 in the first game of the 2019 regular season at the Tokyo Dome in Tokyo, Japan. This was the first of a two-game series that was widely expected to be the finale for Ichiro Suzuki as a player.
 * March 21 – Immediately after the Seattle Mariners' 5–4, 12-inning victory over the Oakland Athletics in the second and final game of their Tokyo series, Ichiro Suzuki goes 0 for 4 as Seattle's right fielder, then leaves after the 8th inning. Ichiro announced his retirement after the game, ending a playing career in both NPB and MLB that spanned 27 seasons.
 * March 23 – The Diablos Rojos del México (Red Devils) opened their new Alfredo Harp Helú baseball stadium in Mexico City.

April

 * April 2 :
 * Ronald Acuña Jr. and the Atlanta Braves agreed to a $100 million, eight-year contract extension, which is the largest deal for a player under club control with less than one year of service. By way of team options for 2027 and 2028, the deal would max out at $124 million over 10 years. At 21, Acuña became the youngest player to sign a nine-figure contract in major league history, while winning the National League Rookie of the Year in 2018. Through 132 career games, the Venezuelan outfielder posted a .293/.366/.552 slash line, including 32 home runs, 26 doubles, 18 stolen bases, a .934 OPS (144 OPS+) and 5.6 WAR, according to Baseball Reference. Besides, Acuña became the seventh big leaguer to hit 25 home runs in a season before his 21st birthday—and the fastest to reach that mark, in 92 games. The other six on the list are Hall of Famers Mel Ott, Frank Robinson, Al Kaline, Orlando Cepeda and Eddie Mathews, as well as the ill-fated Tony Conigliaro.
 * Bryce Harper made his return to Nationals Park for the first time as a member of the Philadelphia Phillies. Showered by jeers for much of the game, Harper rebounded from a pair of early strikeouts against former Washington Nationals teammate Max Scherzer, by hitting a fifth-inning double off Scherzer and a sixth-inning RBI single off reliever Matt Grace before towering a two-run home run off Jeremy Hellickson in the eighth inning, while leading his new team to an 8–2 victory.
 * April 5 – Minnesota Twins shortstop Jorge Polanco hit for the cycle in his first four at-bats of a 10–4 loss to the host Philadelphia Phillies. Besides, Polanco added a single in the ninth inning for his first five-hit game. It was Polanco's first career cycle, as well as the first of the current season, the 15th in franchise history, and the 11th since the Senators franchise became the Twins upon relocating from Washington, D.C., for the 1961 season.
 * April 9 – In Opening Game at Fenway Park, Boston Red Sox manager Alex Cora and Toronto Blue Jays manager Charlie Montoyo made history, when they faced in a Major League game in which both teams were led by Puerto Rican-born managers. Toronto prevailed, 7–5.
 * April 11 – Kansas City Royals outfielder Whit Merrifield saw his team-record hitting streak ended at 31 games, dating back to last season, after he went 0-for-6 in the Royals' 7–6 loss to the Seattle Mariners. The day before, Merrifield had passed George Brett for the longest streak in franchise history, which was set in 1980.
 * April 13 – Baltimore Orioles first baseman Chris Davis ended his historic MLB record slump at 0-for-54 at Fenway Park, hitting a single and two doubles while driving in four runs as the Orioles beat the Boston Red Sox, 9–5, to stop a four-game losing streak. Davis, a two-time major league home run champion, had been 0-for-33 this season, as his single off pitcher Rick Porcello in the first inning was his first hit since September 14 of last season. The previous record for a position player had been established by Eugenio Vélez, a former San Francisco Giants and Los Angeles Dodgers infielder who went 0-for-46 during the 2010 and 2011 seasons. The all-time record for a hitless streak by any player was an 0-for-85 drought by Chicago Cubs pitcher Bob Buhl between 1962 and 1963.
 * April 15 – Christian Yelich hit three home runs and drove in a career-high seven runs to carry the Milwaukee Brewers to a 10–7 win over the St. Louis Cardinals at Miller Park. The Brewers outfielder and reigning National League MVP has now hit seven home runs in his team's five games against the Cardinals to date in 2019. Besides, Yelich previously hit one homer apiece in the four-game season-opening series in Milwaukee, a record-tying start to a regular season.
 * April 19 – Cleveland Indians prospect Will Benson hit four home runs, including a grand slam, to lead the Class-A Lake County Captains past 12–6 the visiting South Bend Cubs at Classic Park. Benson, who drove in eight runs, became the first player to hit four homers in a Midwest League game since Garrett Jones completed the feat for the Quad Cities River Bandits in 2002.
 * April 20 – Los Angeles Angels slugger Albert Pujols surpassed Babe Ruth for fifth place in Major League Baseball history with his 1,993rd career run batted in in a 6–5 loss to the Seattle Mariners at Angel Stadium. Pujols drove home Andrelton Simmons with a double off Seattle's pitcher Yusei Kikuchi in the third inning to tie Ruth. In the ninth inning with the Angels trailing 6–4, Pujols passed Ruth with a solo home run off of Anthony Swarzak. Pujols only surpassed Ruth according to an MLB official starting point for the mark. It was not an official statistic until 1920, when Elias Sports Bureau did not count Ruth's RBIs from 1914 to 1919. Ruth played his first year with the New York Yankees, though his career began in 1914 with the Boston Red Sox. Nevertheless, according to the leaderboard at sites such as Baseball Reference, Ruth would have an overall total of 2,213 RBI, which would rank second all-time behind Hank Aaron with 2,297.
 * April 26 – Three-time Cy Young winner Max Scherzer recorded his 2,500th career strikeout, becoming the third-fastest major league pitcher to reach the plateau, based on innings. The Washington Nationals ace stroke out 10 in seven innings against the visiting San Diego Padres, allowing two runs on four hits and got a no-decision in Washington's 4–3 loss. Scherzer need $2,155 1/3$ innings to achieve his feat. The only pitchers to reach 2,500 strikeouts quicker than Scherzer are Hall of Famers Randy Johnson and Pedro Martínez. Johnson did it in $2,107 2/3$ innings, while it took Martinez $2,152 2/3$ frames. Scherzer has led the National League in strikeouts each of the past three seasons, including last year, when he became the fifth hurler since 2001 to record 300 punchouts in a single season.
 * April 30 – CC Sabathia became the 17th pitcher in Major League Baseball history as well as the third left-hander to reach the 3,000 strikeout club. It took five pitches to Arizona Diamonbacks catcher and former New York Yankees player John Ryan Murphy in the second inning of a Yankees' 3–1 loss at Chase Field. Sabathia left the game after $5 1/3$ innings, having given up two earned runs, five hits and two walks while striking out five. Sabathia joined lefties Randy Johnson and Steve Carlton in the select club. Besides, he is also the second African-American pitcher, after Bob Gibson, to have amassed 3,000 strikeouts in his career. Another pitcher with 3,000 strikeouts, Ferguson Jenkins, is a Black Canadian. These four pitchers are in the Baseball Hall of Fame. In February, two months after an unexpected offseason angioplasty that followed an earlier offseason knee surgery, Sabathia announced he would be retiring after 19 seasons.

May

 * May 3 – Oakland Athletics catcher Josh Phegley went 4-for-5, including two doubles, one home run and eight runs batted in, in a 14–1 rout over the Pittsburgh Pirates at PNC Park. With his eight-RBI performance, Phegley set a single-game record for a catcher in Athletics' 119-year history and also marked the first time any Athletics player reached eight RBI in a game since third baseman Eric Chavez did it on August 30, 2001, against the Baltimore Orioles.
 * May 4 – At t Fenway Park, the Boston Red Sox had a nine-run third inning in a 15–2 rout of the Chicago White Sox that included 10 straight hits, one shy of the major league record set by the Colorado Rockies in a 17–2 win against the Chicago Cubs at Coors Field on July 30, 2010. White Sox starter Manny Bañuelos had retired the first eight Red Sox batters he faced. Carson Fulmer replaced Bañuelos and interrupted the hit parade to end the inning after 14 batters. Red Sox rookie Michael Chavis hit two of the four home runs of Boston. Xander Bogaerts and Eduardo Núñez homered, Mookie Betts and J. D. Martinez had RBI doubles, and Christian Vázquez capped the streak with his second single of the inning.
 * May 7 :
 * Mike Fiers pitched the second no-hitter of his career and the 300th no-hitter in Major League Baseball history, including the postseason, while leading the Oakland Athletics to a 2–0 win over the Cincinnati Reds at Oakland Coliseum. Previously, Fiers threw one no-hitter for the Houston Astros on August 21, 2015, against the Los Angeles Dodgers. Besides, Fiers became the 35th pitcher to throw multiple no-hitters. Four of them still active: Jake Arrieta, Homer Bailey, Max Scherzer and Justin Verlander, according to the Elias Sports Bureau.
 * Justin Turner hit three home runs and drove in a career-high six runs in the Los Angeles Dodgers' 9–0 victory over the Atlanta Braves at Dodger Stadium. This was the first career three-homer game and eighth multi-homer game for Turner, who propelled the Dodgers to the 2017 NL Championship Series title and missed the first six weeks of 2018 with a fractured wrist, ending with a subpar season.
 * May 9 – Los Angeles Angels slugger Albert Pujols recorded his 2,000th career run batted in with a solo home run in the 13–0 rout of the Detroit Tigers at Comerica Park. Pujols became only the third player in Major League Baseball history to collect 2,000 or more RBI in a career, joining Hank Aaron (2,297) and Alex Rodriguez (2,086) in achieving the feat, according to the Elias Sports Bureau – the official statistician of Major League Baseball. Nevertheless, some discrepancies exist between the statistics provided today by different historical data providers. The RBI did not become an official baseball statistic until the 1920 MLB season, so Elias does not count the RBI accrued before that date. That designation wipes out the entire careers of Babe Ruth (2,214 in all; 1,990 in 1920 and later) and Cap Anson (2,075). Besides, the Baseball Almanac and Baseball Reference websites, among others, retroactively added RBI prior to 1920, based largely on research originally spearheaded by sports statistician and editor Pete Palmer for the Total Baseball encyclopedia series.
 * May 14 – Boston Red Sox pitching ace Chris Sale struck out a career-high 17 against the Colorado Rockies at Fenway Park, becoming the first pitcher in Major League Baseball history to strike out 17 or more batters in a start lasting seven innings or fewer. After no-hitting the Baltimore Orioles for $5 2/3$ innings and striking out 14 in his previous start, Sale was perfect through 12 Rockies batters, allowing only two runs, three hits and no walks over seven innings. Even though, Colorado rallied against the Boston bullpen to win 5–4 in the 11th inning. It was also the first 17-strikeout game for a left-handed pitcher since Johan Santana for the Minnesota Twins in 2007. Besides, the Red Sox tied their own franchise record with 24 strikeouts in a game, as their pitchers struck out 21 over the first nine innings. The only other time that has happened in MLB history was when the Red Sox did it against the Tampa Bay Rays on September 25, 2016.
 * May 15 – Toronto Blue Jays pitcher Edwin Jackson made history when he set a Major League Baseball record by playing for the 14th different club during his 17-year career. Jackson made his debut with the Los Angeles Dodgers in his 20th birthday. Afterward, the now 35-year-old has played for the Tampa Bay Rays, Detroit Tigers, Arizona Diamondbacks, Chicago White Sox, St. Louis Cardinals, Washington Nationals, Chicago Cubs, Atlanta Braves, Miami Marlins, San Diego Padres, Baltimore Orioles and Oakland Athletics before joining the Blue Jays. In his debut for them, Jackson pitched five innings without a decision in a 4–3 loss to the San Francisco Giants at Oracle Park. He allowed three runs — two earned — on six hits and one walk while striking out two batters and hitting one, leaving after 77 pitches with the score tied at 3–3.
 * May 17 – Kris Bryant matched a career high with three home runs in a game and drove in five runs, while the Chicago Cubs outscored the Washington Nationals 14–6 at Nationals Park. Bryant went deep in the seventh, eighth and ninth innings, making him the 12th player in Major League Baseball history to homer in three consecutive innings.
 * May 28 – Derek Dietrich enjoyed a career night with three home runs and six runs batted in, while leading the Cincinnati Reds to an 11–6 victory over the Pittsburgh Pirates at Great American Ball Park. Besides, his 17 homers in the season already has set a career high, and 12 of his past 17 hits have been home runs. Dietrich has been successfully replacing the injured slugger Scooter Gennett, sidelined since spring training due to a groin injury. Dietrich did not have another at-bat to try to match Gennett, who tied a major league record with a four-home-run game in 2017.
 * May 29 – Major League Baseball announced that the 2021 MLB All-Star Game will be hosted by the Atlanta Braves at SunTrust Park. Likewise, this will be the third time in franchise history the event has been awarded to the city of Atlanta, who has not hosted an All-Star Game since 2000.

June

 * June 3 – Adley Rutschman became the first overall selection in the 2019 MLB Draft after being selected by the Baltimore Orioles, who had the worst record in 2018.
 * June 9 – Edwin Encarnación hit his 400th home run for the Seattle Mariners in a 9–3 victory over the host Anaheim Angels. Encarnación is now ranked 56th in the List of MLB players with the most home runs. The 36-year-old Dominican Republic slugger has hit 32 or more homers each of those past seven years and is on pace for 50 this season.
 * June 10 – The Philadelphia Phillies and Arizona Diamondbacks combined for 13 home runs, the most in one game in major league history, in a 13–8 Diamondbacks victory. Jarrod Dyson, Ketel Marte, and David Peralta led off the game with three consecutive homers.
 * June 13 – Los Angeles Angels two-way star Shohei Ohtani became the first Japanese-born player to hit for the cycle in the major leagues, helping the Angels defeat the Tampa Bay Rays 5–3 at Tropicana Field. Ohtani slugged a three-run home run in the first inning, hit a double in the third, tripled during the fifth, and then delivered a single against right-hander Hunter Wood in the seventh to accomplish the feat. His first three hits came off left-hander Ryan Yarbrough. A two-way sensation as a rookie last season, Ohtani is not pitching this season as he recovers from Tommy John surgery.
 * June 14 – Jake Bauers of the Cleveland Indians, hit the third cycle of the season, just one day after Shohei Ohtani had hit the second. Bauers completed the cycle with a home run in the eighth inning as Cleveland defeated the host Detroit Tigers, 13–4. Previously, Bauers hit a double in the second, then singled and tripled during the fourth, when the Indians scored eight times. According to the Elias Sports Bureau, this is the third time in Major League Baseball history with cycles in back-to-back days. In the 1912 season, Tris Speaker (June 9) and Chief Meyers (June 10) collected cycles. In 1885, Dave Orr (June 12) and George Wood (June 13) became the first duet to accomplish the feat.
 * June 19 – CC Sabathia notched his No. 250th career game by tossing six innings of three-hit, one-run baseball in a 12–1 New York Yankees victory over the Tampa Bay Rays at Yankee Stadium. Sabathia, who also reached 3,000 career strikeouts on April 30, became just the 14th pitcher in Major League history with at least 250 wins and 3,000 strikeouts. Among the other 13, all but Roger Clemens are in the Baseball Hall of Fame.
 * June 20 – Commissioner Rob Manfred authorized Tampa Bay Rays owner Stuart Sternberg to open discussions towards playing some of the Rays games in Montreal in future years. This comes in response to the lack of progress in plans for a new ballpark to replace the reviled Tropicana Field, and to explore the possibility of becoming a two-city team, starting the season playing home games in their current stadium in St Petersburg and finish their home schedule in Montreal. It would mark the return of Major League Baseball to Montreal for the first time since 2004, when the Expos were relocated to Washington, D.C. before the 2005 season and renamed the Nationals.
 * June 21 :
 * Albert Pujols returned to the city where his career began eight years after he last played in a St. Louis Cardinals uniform. This time Pujols wore a Los Angeles Angels uniform, and he received an emotional standing ovation from the sellout crowd of 48,423 at Busch Stadium every time he came to bat, as the fans chanted his name. He went 1-for-2 and received a walk. St. Louis won the first of three-game series, 5–1. Pujols, who spent the first 11 years of his career with the Cardinals, led them to two World Series championships, won three National League MVP awards, a batting title, and earned nine All-Star selections. He was cheered again when he beat out an infield single to lead off the seventh inning, receiving a final standing ovation after being lifted for pinch-runner Wilfredo Tovar.
 * Walker Buehler pitched a two-run, three-hit complete game and recorded a career-high 16 strikeouts, while rookie Matt Beaty hit a two-out, two-run, walk-off home run in the ninth inning and the Los Angeles Dodgers beat the Colorado Rockies, 4–2, at Dodger Stadium.
 * June 23 – The Chicago Cubs beat the New York Mets at Wrigley Field, 5–3. Javier Báez hit the 100th homer of his career, a three-run shot in the eighth inning, while Pete Alonso set the Mets' record for home runs by a rookie, hitting his 27th of the season, breaking the mark established by Darryl Strawberry in the 1983 season.
 * June 26 – Vanderbilt University defeated the University of Michigan 8–2 in the third and final game of the 2019 College World Series. It was the second title in school history, the other having been won in 2014. Vanderbilt Commodores freshman pitcher Kumar Rocker earned CWS Most Outstanding Player honors.
 * June 29 – The first MLB game ever played in Europe featured the New York Yankees defeating the Boston Red Sox, 17–13, before 59,659 spectators at London Stadium in London. At four hours 42 minutes, the game was only three minutes shorter than the longest nine-inning game in MLB history, also played between the Red Sox and Yankees on August 18, 2006.

July

 * July 3 :
 * Washington Nationals pitcher Stephen Strasburg struck out 14 in $7 1/3$ shutout innings, including an immaculate fourth inning, and the Nationals continued their midseason surge with a 3–1 victory over the visiting Miami Marlins. Strasburg completed the feat striking out Garrett Cooper, Neil Walker and Starlin Castro on just nine pitches, allowing two hits and two walks, but did not get a runner past first base until the eighth inning.
 * Philadelphia Phillies outfielder Bryce Harper hit a solo home run in the sixth inning in the Phillies' 9–2 loss to the Atlanta Braves at SunTrust Park. It was his 200th career homer and 1,000th career hit, making Harper the first player in Major League Baseball history to have two milestone hits in the same at-bat. His homer came on a first-pitch fastball from Braves rookie pitcher Bryse Wilson, who allowed two runs in six innings and got his first win in just his fourth career start.
 * July 6 – Max Scherzer stroke out 11 batters in seven scoreless innings, hit a single and stole a base for the second time in his career, leading the Washington Nationals to a 6–0 win over the visiting Kansas City Royals. To celebrate the 50th anniversary of the franchise, the Nationals played the game wearing the powder blue road uniforms of the 1969 Montreal Expos, who joined the National League as an expansion team in that season. Following the 2004 season, the franchise relocated to Washington, D.C.
 * July 9 – The American League defeated the National League, 4–3, in the 90th Annual MLB All-Star Game played at Progressive Field in Cleveland, Ohio. Cleveland Indians pitcher Shane Bieber won the All-Star Game MVP Award honors after striking out the side in his only inning of work. Bieber stroke out Willson Contreras, Ketel Marte and Ronald Acuña Jr. in succession in the fifth, while protecting a 1–0 lead. Bieber is the third player in All-Star Game history to win the MVP award in his home ballpark, joining Pedro Martínez, who did it at Fenway Park in 1999, and Sandy Alomar Jr., also in Cleveland in 1997. The 2020 MLB All-Star Game will be played at Dodger Stadium, returning to the ballpark for the first time since 1980.
 * July 12 - In their first home game since the death of Tyler Skaggs on July 1, and one day before what would have been his 28th birthday, the Los Angeles Angels of Anaheim honored the late pitcher by wearing his #45 jersey and by inviting his mother, Debbie Hetman, onto the field for the ceremonial first pitch. Taylor Cole and Félix Peña then combined to no-hit the Seattle Mariners, 13–0, Cole pitching the first two innings, Peña the last seven for the victory. After the game, the Angels took off their Skaggs jerseys and laid them out on the mound as a tribute. In the last combined no-hitter pitched in California, four Baltimore Orioles had combined to no-hit the Oakland Athletics 2–0 at Oakland-Alameda County Coliseum on July 13, 1991—the day Skaggs was born.
 * July 14 – At Oriole Park at Camden Yards, the visiting Tampa Bay Rays had what would have been the first-ever combined perfect game in Major League Baseball history, as starter Ryne Stanek retired the first six Baltimore Orioles batters he faced and reliever Ryan Yarbrough retired the next 18 in order, before Hanser Alberto beat the Rays' overshifted infield with a leadoff opposite-field single against Yarbrough in the ninth inning. Stevie Wilkerson followed with a single, and a two-out RBI-single by Anthony Santander off reliever Oliver Drake enabled Baltimore to break up the shutout, but still lose the game, 4–1. Emilio Pagán struck out Trey Mancini for the final out and was credited with the save.
 * July 15 – San Francisco Giants shortstop Brandon Crawford went 6-for-9, hit three home runs, drove in nine runs and scored four more times in a doubleheader against the Colorado Rockies at Coors Field. In the opener, Crawford paced the offense with five hits, homered twice and posted a career-high eight RBI, as the Giants routed Colorado, 19–2. Crawford became the third Giants player since the franchise moved to San Francisco in 1958 to drive in eight runs in a single game, joining legends Willie Mays (April 30, 1961) and Orlando Cepeda (July 4, 1961). But his third homer was much more significant in the night cap, being the difference in the 2–1 victory and to complete a sweep of a split doubleheader.
 * July 19 – Mike Leake of the Seattle Mariners pitched a perfect game into the ninth inning before giving up a leadoff single to Luis Rengifo of the Los Angeles Angels. Leake settled for a one-hitter shutout in a 10–0 win.
 * July 20 – At PNC Park, the Pittsburgh Pirates celebrated the 40th anniversary of the 1979 team that won the World Series, taking a 5–1 victory over the visiting Philadelphia Phillies. During the pregame ceremony, all the members of the 1979 team in attendance reflected about Willie Stargell and what he meant to the Pirates as a leader of that team on and off the field. Among them were Matt Alexander, Dale Berra, John Candelaria, Mike Easler, Tim Foli, Clint Hurdle, Grant Jackson, Lee Lacy, Omar Moreno, Steve Nicosia, Ed Ott, Dave Parker, Don Robinson, Jim Rooker, Manny Sanguillén, Rennie Stennett and Kent Tekulve. Both current and veteran Pirates players wore the trademark black uniforms with striped pillbox caps the 1979 group led by Hall of Famer Willie Stargell.
 * July 23 – Trea Turner hit his second career cycle, Stephen Strasburg earned his major league-leading 13th win and the Washington Nationals routed the Colorado Rockies, 11–1, at Nationals Park. Turner delivered his first cycle against Colorado in 2017, making him just the 26th player in MLB history to accomplish the feat more than once and the third player to do so against the same team, joining Fred Clarke (1901 and 1903 against Cincinnati) and Christian Yelich (in 2018 against Miami).
 * July 24 – Shane Bieber pitched a one-hitter shutout in a 10-strikeout performance, allowing only a double by Eric Sogard in the seventh inning, as the Cleveland Indians beat the Toronto Blue Jays, 4–0, at Rogers Centre. On July 9, Bieber went on to win the All-Star Game MVP award after striking out the side on 19 pitches in the fifth inning.
 * July 25 – Baltimore Orioles outfielder Stevie Wilkerson becomes the first position player to ever earn a save in Major League Baseball history, as he pitches a perfect 16th inning to preserve a 10–8 victory over the Los Angeles Angels at Angel Stadium. Wilkerson, who started the game at center field, was the 10th pitcher of the night for Baltimore, as he used slow lobs never topping 55 mph to put an end to a game that lasted 6 hours and 19 minutes, which is the second-longest game in Orioles history.
 * July 26 – Boston Red Sox outfielder Mookie Betts hit three home runs in a 10–5 victory over the New York Yankees at Fenway Park. In doing so, Betts made it four straight days where at least one big leaguer has posted a three home run game, which is the longest streak in Major League Baseball history. It started on June 23, when New York Mets second baseman Robinson Canó went deep three times. Then St. Louis Cardinals shortstop Paul DeJong and Minnesota Twins slugger Nelson Cruz did the same within the next two days respectively. It was the fifth time Betts hit three homers in a game, as he extended his own club record. Only eight players in MLB history have had five games with three homers or more. Besides, Betts became the fourth Red Sox player to achieve a three-homer game against the Yankees at Fenway Park, joining Mo Vaughn (May 31, 1997), Kevin Millar (July 24, 2004) and Steve Pearce (August 2, 2018).
 * July 31 – At the MLB Trade Deadline, the Houston Astros obtained starting pitcher Zach Greinke from the Arizona Diamondbacks in exchange for four prospects.  Their rotation is now Justin Verlander, Gerrit Cole and Greinke, plus Wade Miley if necessary. In a separate transaction, the Astros bolstered its bullpen with the acquisition of starter Aaron Sanchez and reliever Joe Biagini from the Toronto Blue Jays in exchange for outfielder Derek Fisher and a prospect.

August

 * August 3:
 * Three days after being acquired at the trade deadline, veteran starter Aaron Sanchez pitched six no-hit innings in a Houston Astros uniform, while combining with relievers Will Harris, Joe Biagini and Chris Devenski to throw the 12th no-hitter in franchise history in a 9–0 wipeout of the Seattle Mariners Mariners at Minute Maid Park. It was the second time in less than a month the last-place Mariners were no-hit by multiple pitchers. Previously, the Los Angeles Angels used starter Taylor Cole and reliever Félix Peña on July 12, in a 13–0 combined no-hitter against Seattle on a night when they honored late left-hander Tyler Skaggs by all wearing his No. 45 in their first home game since his death.
 * Nelson Cruz hit three home runs in a game for the second time in 10 days, while powering the Minnesota Twins to an 11–3 victory over the Kansas City Royals at Target Field. In between, Cruz has collected 11 homers and 23 runs batted in in his past nine starts. Only two other players in Major League History have had two three-homer games within 10 days. Doug DeCinces accomplished the feat for the California Angels on August 3 and August 8, 1982, and Johnny Mize did it for the St. Louis Cardinals on July 13 and July 20, 1938. Besides, Cruz is the only big leaguer with multiple three-homer games after his 39th birthday.
 * August 8 – MLB announced that the Chicago White Sox and New York Yankees would play a regular-season game at the Field of Dreams movie site near Dyersville, Iowa on August 13, 2020. To be marketed as "MLB at Field of Dreams", it will be the first MLB game ever to be played in Iowa, and will be played in an 8,000-seat temporary park to be built on the site. As the first of a three-game White Sox series with the Yankees, with the other two to be held at the Sox' regular home of Guaranteed Rate Field, it will be counted as a White Sox home game.
 * August 13 :
 * Chris Sale of the Boston Red Sox became the fastest pitcher in Major League Baseball history to record 2,000 strikeouts in the 7–6 victory over the host Cleveland Indians that lasted ten innings, while Jackie Bradley Jr. made the difference with a solo home run in the top of the 10th. Sale entered the game with 1,995 strikeouts and struck out Oscar Mercado in the third inning to reach the milestone in 1,626 innings, breaking the mark set by Hall of Famer Pedro Martínez, who reached it in $1,711 1/3$ innings. Career strikeout leader Nolan Ryan (5,714) needed $1,865 2/3$ innings. Sale finished with 12 strikeouts in $6 2/3$ innings of work and did not factor in the decision. Besides, Red Sox third baseman Rafael Devers went 6-for-6 with four doubles, becoming the first player in Major League history to record six or more hits and four or more doubles in one game.
 * The Philadelphia Phillies hired former manager Charlie Manuel as their hitting coach in replacement of John Mallee. Manuel, the winningest manager in franchise history, guided the Phillies to the 2008 World Series title, two National League pennants and five consecutive NL East titles from 2007 through 2011. Manuel returned to his old dugout with a new role six years after earning his 1,000th career managerial victory and being dismissed during his only losing season in Philadelphia. Afterwards, he worked as a senior adviser to general manager Matt Klentak. The move represented an attempt to spark a talented but underachieving offense and salvage a season that carried high expectations. At this time, the Phillies entered in fourth place in the division, but only two games back of the second NL Wild Card spot.
 * August 14 – Los Angeles Angels slugger Albert Pujols collected two hits and drove in three runs, leading the Angels to a 7–4 victory over the visiting Pittsburgh Pirates, while setting the Major League record for hits by a foreign-born player. With 3,167 hits, Pujols surpassed fellow Dominican Republic native Adrián Beltré (3,166) and took sole possession of 15th place for career hits in MLB history. Besides, Pujols is already the all-time leader among foreign-born players in home runs (651), doubles (653), runs scored (1,815) and RBI (2,052).
 * August 22 :
 * Major League Baseball decided to preclude their Major and Minor leagues ball players from participating in the Venezuelan Professional Baseball League this winter. The move was made as MLB seeks clarification in an effort to comply with the economic sanctions imposed by the United States against the government of Venezuela earlier this year.
 * Tampa Bay Rays right fielder Austin Meadows hit a solo home run in the third inning off Baltimore Orioles pitcher Asher Wojciechowski, as the Orioles allowed their 259th home run of the season, breaking the Major League Baseball single-season record held by the 2016 Cincinnati Reds. Baltimore still has 34 more games remaining.
 * August 23 – Eight New York Mets pitchers combined to tie a Major League Baseball record with 26 strikeouts during a 2–1 home loss in 14 innings to the National League East rival Atlanta Braves. Mets starter Jacob deGrom stroke out 13 batters and hit a solo home run before exiting after seven innings with the score tied 1–1. The Mets became just the fifth team in MLB history to record 26 strikeouts in a game, while the Braves joined the 2004 Milwaukee Brewers as the only teams to win despite that many strikeouts, according to ESPN News Services.
 * August 31 – Minnesota Twins catcher Mitch Garver hit a home run in the 9th inning of a 10–7 loss to the Detroit Tigers at Comerica Park. It was also the 268th home run hit by a Twins batter in 2019, setting the MLB record for long balls by a club in a single season, while surpassing the 2018 New York Yankees with another month still to play.

September

 * September 1 – Justin Verlander of the Houston Astros pitches his third career no-hitter in a 2–0 victory over the Toronto Blue Jays at Rogers Centre. He struck one 14 and gave up a walk. His first no-hitter came in 2007 at Comerica Park against the Milwaukee Brewers while pitching for the Detroit Tigers. In 2011, Verlander hurled his second no-no against the Blue Jays on the same Rogers Centre ballpark, becoming the third pitcher in Major League Baseball history to throw multiple no-hitters against the same team as well as the first to throw two in the same ballpark as a visitor. By no-hitting Toronto, Verlander also joined Nolan Ryan (7), Sandy Koufax (4), Larry Corcoran, Bob Feller and Cy Young as the sixth pitcher to throw three or more no-hitters in their major league careers.
 * September 2:
 * One day after Justin Verlander's no-hitter, in which he struck out 14 batters, Houston Astros teammate Gerrit Cole strikes out 14 Milwaukee Brewers in six innings at Miller Park. The Astros defeat the Brewers 3–2 on George Springer's 10th inning home run. According to Elias Sports Bureau, Cole's feat makes the Astros the first team to have pitchers with at least 14 strikeouts in consecutive games since the mound was moved to 60 feet, six inches in 1893.
 * At Yankee Stadium, the Texas Rangers shut out the New York Yankees, 7–0, ending the Yankees' streak of consecutive games without being shut out at 220. The Yankees had last been shut out on June 30, 2018, by the Boston Red Sox, 11–0. The streak of consecutive games without being shut out was the second-longest in Major League history. Besides, the Yankees also hold the #1 record, having scored at least one run in 308 consecutive games from 1931 to 1933.
 * September 3 – Kansas City slugger Jorge Soler hit his 39th and 40th home runs of the season in the 5–4 victory over the Detroit Tigers at Kauffman Stadium. As a result, the Royals became the last team in Major League Baseball history to have a player reach 40 home runs in a single season. Prior to this date, Mike Moustakas held the club record with 38 homers in 2017.
 * September 4:
 * Two-way player Michael Lorenzen became the first big leaguer in 98 years to earn the win as a pitcher, hit a home run, and play in the field in the same game since Babe Ruth in 1921. Lorenzen pitched in the seventh and eighth innings, hit a two-run homer in the eighth, turning an uncomfortable one-run lead into a three-run advantage, and finished the game in center field while watching the Cincinnati Reds defeat the Philadelphia Phillies, 8–5, at Great American Ball Park. Ruth accomplished the feat for the New York Yankees against the Detroit Tigers at the Polo Grounds on June 13, 1921.
 * The Los Angeles Dodgers set a new single-season National League record for team home runs with 250, surpassing the old mark set by the 2000 Houston Astros. In the same game, Joc Pederson tied Larry Walker of the 1996 Rockies for a NL record for consecutive at-bats with an extra-base hit with six.
 * September 5 – Class A Lowell Spinners pitcher Yusniel Padrón-Artiles struck out 12 consecutive Batavia Muckdogs, which set both an MLB and Minor League record for the most strikeouts in a row. Lowell prevailed, 2–1, when Joe Davis hit a walk-off homer in the bottom of the ninth. Padrón-Artiles, a 21-year-old Cuban prospect of the Boston Red Sox, relieved Jay Groome in the fourth, went six extremely strong innings, allowing just one hit while striking out a career-high 14 batters overall.
 * September 9 – Short after midnight, the Boston Red Sox announced that they had dismissed president of baseball operations Dave Dombrowski. Assistant general managers Eddie Romero, Zack Scott and Brian O'Halloran, and senior VP of Major League and minor league operations Raquel Ferreira will take over as the heads of the baseball operations department for the remainder of the season. Dombrowski was under contract through the 2020 season. The Red Sox hired Dombrowski on August 18, 2015, to replace Ben Cherington. During his tenure, Dombrowski won three straight American League East titles (2016–2018) and the 2018 World Series championship, but the Boston club have had a difficult 2019 season to stay afloat. Multiple issues surrounded the decision, as the team exceeded the upper level of the luxury tax ($237MM) in 2018 and were again in position to exceed the new upper threshold of $246MM this season. Besides, the Red Sox have a projected luxury tax number of over $257.7MM, putting them in line to face another maximum penalty — a 75 percent tax on the overage, as well as a drop of ten spots for their highest pick of the 2020 MLB Draft.
 * September 17 - At Oriole Park at Camden Yards, Cavan Biggio of the Toronto Blue Jays hits for the cycle in an 8–5 victory over the Baltimore Orioles. With his father Craig having performed the feat on April 8, 2002, the Biggios become the second father-and-son duo, after the Wards, to hit for the cycle, Gary having done so on September 18, 1980 and his son Daryle on May 26, 2004.
 * September 18 :
 * San Francisco Giants manager Bruce Bochy won the 2,000th game of his MLB managerial career, as the Giants defeated the Red Sox, 11–3, at Fenway Park. Bochy, who became just the 11th big league manager to reach the 2,000-win milestone, accomplished the feat on his 25th and final season. In the same game, Red Sox third baseman Rafael Devers connected his 30th home run of the season, joining teammate Xander Bogaerts to become the first pair of teammates to collect 30-plus home runs and 50-plus doubles in an MLB single season.
 * The New York Mets hit their 225th home run of the season, becoming the 10th MLB team to break their single-season franchise home run record in 2019. The record-breaking home run was hit by Pete Alonso, his 49th of the season.
 * Gerrit Cole of the Houston Astros became just the 18th pitcher in Major League Baseball history to notch 300 strikeouts in a season during a 3–2 win over the Texas Rangers at Minute Maid Park. The right-hander struck out 10 batters while allowing just two earned runs and six hits in eight innings of work.
 * September 20 – New York Mets rookie first baseman Pete Alonso hit his MLB-leading 50th home run, while Jacob deGrom pitched shutout ball for seven innings and the Mets beat the Cincinnati Reds, 8–1, at Great American Ball Park. Alonso is now close to New York Yankees outfielder Aaron Judge, who set a season record for a rookie with 52 homers in 2017. Besides, Alonso became only the 30th player in MLB history to join the 50-home run club and the first Met to do so, according to New York Post.
 * September 22 – Minnesota Twins slugger Nelson Cruz hit his 400th career home run and 40th of the season against the Kansas City Royals at Target Field. With it, Cruz became the 57th player in Major League Baseball history to reach the 400 home runs mark. In addition, Cruz became the third player in Twins history to hit 40 home runs in a season, joining Harmon Killebrew and Brian Dozier as well as the 26th big leaguer with four 40-home run seasons.
 * September 23 – Ned Yost announced that he will retire from managing the Kansas City Royals at the end of the season. Yost, who managed the team since the 2010 season, will finish his career with the most victories in Royals franchise history and is the only Royals manager to ever make consecutive postseason appearances, winning two American League pennants from 2014 to 2015 and the 2015 World Series title.
 * September 28 – New York Mets first baseman Pete Alonso slugged his 53rd home run in the Mets 3–0 win over the Atlanta Braves at Citi Field, to break the MLB rookie record set by New York Yankees outfielder Aaron Judge in the 2017 season.
 * September 29 :
 * The Chicago Cubs announced that they would not be offering manager Joe Maddon a contract extension for the upcoming season. Signed prior to the 2015 campaign, Maddon became the only manager in Cubs history to lead the team to four consecutive postseason berths, reaching the National League Championship Series from 2015 to 2017 while winning the 2016 World Series title, the first one for the franchise since 1908. The Cubs also moved into 2019 with mostly the same roster in place due to budgetary restraints, but with the most robust payroll in team history. Nevertheless, injuries and inconsistency and a down-the-stretch collapse all conspired to keep the Cubs out of the 2019 postseason for the first time during Maddon's tenure.
 * The Pittsburgh Pirates dismissed manager Clint Hurdle, even though he had two years remaining on his current contract. Hurdle managed the Pirates since the 2011 season and finished as the fourth-winningest manager in franchise history, leading his Pirates teams to an overall 735–720–1 record in his nine years at the helm, including three consecutive postseason appearances from 2013 to 2015. Hurdle was named National League Manager of the Year in 2013, when the Pirates brought postseason baseball back to Pittsburgh for the first time in 20 years. The team peaked with 94- and 98-win seasons in 2013 and 2015, though they were unable to make it out of the Division Series in that three-year stretch—and, in 2014 and 2015, they were eliminated in the one-game playoff.
 * September 30 – The Los Angeles Angels announced that they have dismissed manager Brad Ausmus, ending his tenure after one season. The Angels posted a 72–90 record with Ausmus at the helm.

October

 * October 1 – Juan Soto delivered a bases-loaded single against Josh Hader that scored three runs with two outs in the bottom of the eighth inning, and the Washington Nationals rallied to beat the Milwaukee Brewers 4–3 in the National League Wild Card Game at Nationals Park. As a result, the Nationals advanced to face the NL West champion Los Angeles Dodgers in the best-of-five Division Series.
 * October 2 – The Tampa Bay Rays hit four home runs, two of them by Yandy Diaz,  to beat the Oakland Athletics, 5–1, in the American League Wild Card Game at RingCentral Coliseum. The Rays made their first trip to the postseason since 2013, while advancing to meet the AL West champion Houston Astros in the best-of-five Division Series. This was the third victory for pitcher Charlie Morton in a winner-take-all postseason contest, a first in MLB history, as he also won Game 7 of both the AL Championship Series and World Series in 2017 while pitching for the Astros.
 * October 3 :
 * The New York Mets dismissed manager Mickey Callaway after two seasons with the club. A first-time manager, Callaway posted a 163–161 record overall, going 77–85 during his first year on the job and 86-76 this season.
 * At SunTrust Park, the St. Louis Cardinals scored four runs against Atlanta Braves closer Mark Melancon on two-run doubles by Marcell Ozuna and Kolten Wong in the ninth inning to defeat the Atlanta Braves, 7–6, in Game 1 of the NLDS.
 * The Los Angeles Dodgers won Game 1 of the NLDS over the Washington Nationals at Dodger Stadium, 6–0, behind a dominant pitching performance by Walker Buehler, who threw six scoreless innings of one-hit ball with eight strikeouts. Max Muncy drove in three runs, while Joc Pederson and Gavin Lux added solo home runs.
 * October 4 :
 * In the first of four postseason games, Justin Verlander turned in a dominant pitching performance as the Houston Astros defeated the Tampa Bay Rays, 6–2, in Game 1 of the ALDS at Minute Maid Park. Verlander allowed just one hit in seven scoreless innings while striking out eight. José Altuve opened the scoring with a two-run home run off Tyler Glasnow in the fifth.
 * In the NLDS, the Atlanta Braves received a solid start from Mike Foltynewicz, who pitched seven scoreless innings to beat the St. Louis Cardinals, 3–0, in Game 2 at SunTrust Park. Cardinals starter Jack Flaherty allowed a first-inning run but was dominant after that until surrendering a two-run home run to pinch-hitter Adam Duvall with two outs in the seventh. Closer Mark Melancon was credited with the save, coming off a dreadful night in Game 1. Afterwards, both teams are tied at one win apiece.
 * The New York  Yankees collected a 10–4 victory over the Minnesota Twins in Game 1 of the ALDS at Yankee Stadium, while defeating Minnesota for the 11th straight time in a postseason confrontation to set a Major League Baseball record.
 * In the final game of the day, the Washington Nationals evened the other NLDS one game apiece with a 4–2 win over the host Los Angeles Dodgers. The Nationals had a strong performance from starter Stephen Strasburg, who gave up just one run in six innings while striking out 10. The Nationals took advantage of yet another shaky postseason start by Dodgers star Clayton Kershaw to score three runs in the first two innings. In an interesting move, Strasburg was relieved by ace starter Max Scherzer in the eighth inning in what was a must-win game, and Scherzer stroke out the side on 14 pitches.
 * October 5 :
 * In AL Division Series action, the New York Yankees continued their long-running October dominance of the visiting Minnesota Twins, earning an 8–2 victory en route to a 2–0 advantage in the best-of-five series. New York scored seven runs in the inning, sending 12 men to the plate, culminating with a grand slam by Didi Gregorius which gave the Yankees an 8–0 lead. Game 3 is scheduled on October 7 at Target Field.
 * Gerrit Cole delivered a masterful pitching performance, striking out 15 Tampa Bay Rays batters in $7 2/3$ innings of work to lead the Houston Astros to a 3–1 win in the other AL Division Series at Minute Maid Park. Alex Bregman hit a solo home run for Houston as Martín Maldonado and Carlos Correa drove in the other two runs. The victory gave the Astros a 2–0 stranglehold on the best-of-five series as it shifts to Tampa for Game 3 on October 7.
 * October 6 :
 * At Busch Stadium, the Atlanta Braves rallied past the St. Louis Cardinals 3–1 to take a 2–1 lead in the NL Division Series. Atlanta starter Mike Soroka surrendered two hits, stroke out seven and allowed one run over seven stellar innings. Meanwhile, the Braves had managed just four hits off St. Louis starter Adam Wainwright and reliever Andrew Miller during eight innings before breaking against closer  Carlos Martínez, who surrendered an RBI double to Dansby Swanson with two outs in the ninth to tie the game and later a decisive two-run single to  Adam Duvall.
 * At  Nationals Park, Justin Turner capped a seven-run sixth inning with a three-run home run off starter-turned-reliever Patrick Corbin  and beat the Washington Nationals, 10–4, to grab a 2–1 lead in their best-of-five series.
 * October 7 :
 * In the first of four Divisions Series games, Kevin Kiermaier hit a go-ahead, three-run home run in the second inning against Zack Greinke, as the Tampa Bay Rays backed another clutch playoff pitching performance by Charlie Morton to beat the Houston Astros at  Tropicana Field, 10–3, and cut their AL Division Series deficit to 2–1. Facing the club he helped win the World Series two years ago, Morton allowed one run and three hits while striking out nine over five innings. Afterwards,  Morton is 4–0 with an 0.95 ERA in four career elimination starts, including both the AL Championship Series and World Series in 2017 while pitching for the Astros and the AL Wild Card game win over the Oakland Athletics on October 2.
 * At Busch Stadium, the St. Louis Cardinals beat the Atlanta Braves in extra innings, 5–4, to even the NL Division Series two-game apiece. Yadier Molina anchored the victory, as he hit the game-tying RBI single in the eighth inning and drove in the walk-off winning run in the 10th inning on a sacrifice fly off Braves pitcher Julio Teherán. The victory forced a winner-take-all Game 5 on October 8 at SunTrust Park in Atlanta.
 * In the verge of elimination, Ryan Zimmerman hit a three-run home run and Max Scherzer pitched seven innings of one-run ball, and the Washington Nationals defeated the visiting Los Angeles Dodgers, 6–1, in Game 4 of the NL Division Series. Game 5 will be played at Los Angeles and, for the fourth time in franchise history, the Nationals will attempt to win a decisive Game 5 and their first playoff series ever.
 * In the final game, the New York Yankees swept the Minnesota Twins in three games, winning 5–1, in front of a sellout crowd at Target Field, while advancing to the American League Championship Series. Yankees starter Luis Severino pitched four scoreless innings and Chad Green, the third of five Yankees relievers, got four outs for the win. Second baseman Gleyber Torres  fueled the offensive, hitting a second-inning home run, scoring after each of his two doubles, and delivering a pair of sparkling defensive plays. AL Central champion Minnesota became the first 100-win team swept in the Division Series and dropped to 2–16 against the Yankees in the playoffs.
 * October 8 – The Tampa Bay Rays chased Justin Verlander early en route to a 4–1 victory at Tropicana Field to even the best-of-five series at two games apiece. Tommy Pham and Willy Adames homered and Ryan Yarbrough combined with five other pitchers on a six-hitter for Tampa Bay, while Cy Young Award winner Blake Snell came out of the bullpen for his first career relief appearance, holding off Houston in the ninth inning to earn the save. Verlander, starting on short rest, lasted just $3 2/3$ innings, allowing three runs in the first inning and one more in the fourth, for his shortest career start. Previously, Austin Meadows hit an Opening Day leadoff home run off the right-hander, and that was the last run Tampa Bay scored off Verlander in $19 1/3$ innings, including seven shutout innings in Game 1 of the ALDS. The decisive Game 5 is scheduled at Minute Maid Park on October 10.
 * October 9 :
 * The St. Louis Cardinals scored 10 runs in their first time at bat up and routed the Atlanta Braves, 13–1, in decisive Game 5 of the NL Division Series at SunTrust Park, to set the most productive first inning in postseason history. After pitching seven scoreless innings in a Game 2 victory, Braves starter Mike Foltynewicz retired only one hitter and allowed seven runs before being yanked.

 * As part of this reduction, the Short-Season A classification would be eliminated, and the Rookie classification would be restricted to the complex-based leagues.
 * MLB would take effective control over team affiliations, replacing the current two-year contracts between MLB and MiLB teams with longer-term agreements.
 * Leagues would be reorganized to be more geographically compact. The classifications of surviving teams would also be dramatically shuffled, with some teams being asked to move directly from Class A to Triple-A, or vice versa.
 * The Major League Baseball draft would be moved to follow the College World Series, and reduced from its current 40 rounds to between 20 and 25.
 * MLB proposed the establishment of what it calls the "Dream League", jointly operated by MLB and MiLB and consisting of the teams eliminated from the affiliated system. This league would be open only to undrafted players.
 * MLB teams would be limited to operating five MiLB teams in the U.S. (or Canada)—four full-season affiliates, plus one complex-based Rookie-level team. Each MLB team would also be limited to between 150 and 200 players under MiLB contracts.
