Major League Baseball final standings

 * January 8 – The San Diego Padres sign pitcher Fernando Valenzuela as a free agent.
 * January 9 – The Detroit Tigers sign Vince Coleman as a free agent. Coleman appears in just six games, getting one hit in fifteen plate appearances before announcing his retirement mid-season.
 * January 13 – The San Diego Padres purchased the contract of Hideki Irabu from Chiba Lotte of the Japan Pacific League.
 * January 27 – Jose Canseco returns to the Oakland A's after he's traded there by the Boston Red Sox in exchange for pitcher John Wasdin and cash considerations.
 * February 7 - The Chicago White Sox sign pitcher Danny Darwin as a free agent.
 * February 17 – Deion Sanders returns to baseball after signing a free agent contract with the Cincinnati Reds.
 * February 20 – The Philadelphia Phillies sign free agent outfielder Danny Tartabull. Tartabull will break his foot on Opening Day and sit out the year before retiring.
 * March 5 – Nellie Fox, Tommy Lasorda and Negro leaguer Willie Wells are elected to the Hall of Fame by the Veterans Committee.
 * March 20 - The Atlanta Braves signed Hensley Meulens, who was attempted to return to the majors after spending the previous two seasons in Japan.
 * March 26 – Todd Van Poppel, who had one time been one of baseball's top prospects, is released by the Anaheim Angels. Van Poppel would spend the entire 1997 season out of organized baseball.
 * Bob Hamelin, who just a few seasons prior, had been rookie of the year, was released by the Kansas City Royals.
 * March 31 - Jim Abbott is released by the Anaheim Angels.

April–May

 * April 4 – Bartolo Colón makes his major league debut starting for the Cleveland Indians. Colon gives up six hits in five innings as Cleveland lost to Anaheim 8-6. Colon would go on to pitch 21 years in the major leagues.
 * April 5 – Larry Walker hits 3 home runs helping the Colorado Rockies beat Montreal Expos 15–3.
 * April 10 – At Wrigley Field, Alex Fernandez of the Florida Marlins has a no-hitter broken up in the ninth inning of a 1-0 victory over the Chicago Cubs. With one out in the inning, Dave Hansen hits a ground ball that goes under Fernandez's glove and off his right leg. Brian McRae and Brant Brown then reach on errors, but José Hernández, pinch-running for Hansen, is thrown out on the latter play. Hernández then strikes out Ryne Sandberg for the final out. The no-hitter would have been the first against the Cubs since Sandy Koufax's perfect game in 1965. The loss also extends the Cubs' season-opening losing streak to eight games, the most to start a season in the franchise's 122-year history; they will extend the losing streak to 14 games before finally winning their first game on April 20 against the New York Mets.
 * April 11 – To commemorate the 50th anniversary of the baseball color line, Sharon Robinson, Jackie Robinson's daughter, and Pumpsie Green each throw out the ceremonial first pitch at Fenway Park. In 1959, Green became the first African-American baseball player to appear in a Boston Red Sox uniform, making the Red Sox the last team to integrate in the major leagues.
 * April 15 – On the fiftieth anniversary of Jackie Robinson's first game, all Major League baseball games are stopped so that fans across the country may witness a special presentation at Shea Stadium. With then U.S. President Bill Clinton alongside, acting Commissioner Bud Selig announces that Robinson's uniform #42 will be retired from all Major League teams in perpetuity, with exceptions made for players currently wearing #42 in honor of Robinson.
 * April 25 – Ken Griffey Jr. hits three home runs helping the Seattle Mariners beat the Toronto Blue Jays, 13–8.
 * April 29 – Chili Davis' 300th home run, leading off the 10th inning, snaps a 5–5 tie and gives the Kansas City Royals a 6–5 win over the Toronto Blue Jays.
 * May 1 - The Boston Red Sox sell the contract of pitcher Johnny Ruffin to the Kintetsu Buffaloes.
 * May 7 – The Montreal Expos score a National League-record 13 runs in the sixth inning of their game against the San Francisco Giants on the way to a 19–3 win. The Expos send 17 batters to the plate. Mike Lansing homers twice in the inning to drive in five runs, becoming the third Expos player to perform the feat, and the first NL second baseman to do so since Bobby Lowe in 1894.
 * May 8 – At home, the Baltimore Orioles stop Randy Johnson's 16-game win streak with a decisive 13–3 pasting of the Seattle Mariners. Baltimore is led by catcher Chris Hoiles, who collects six RBI on two homers and a double. Johnson strikes out 10 in six innings, but gives up five runs on six hits and two walks in his attempt to become the first AL pitcher since Dave McNally (1968–69) to win 17 straight.
 * May 13 – Eddie Murray gets two hits in Anaheim's 8–7 win over the Chicago White Sox. The game is the 3,000th of Murray's career, making him only the sixth player in history to reach that mark, joining Pete Rose, Carl Yastrzemski, Hank Aaron, Ty Cobb and Stan Musial.
 * May 21 – Roger Clemens fires the Toronto Blue Jays past the New York Yankees 4–1, for his 8th win of the year against no losses. The Rocket wins his 200th game, the 94th pitcher to reach the 200 victories mark.
 * May 25 – The Minnesota Twins retire Kirby Puckett's uniform number 34 in a 90-minute pregame ceremony.
 * May 26:
 * In the Chicago Cubs' 2–1 win over the Pittsburgh Pirates, Cub Sammy Sosa and Pirate Tony Womack both hit inside-the-park home runs in the sixth inning. It is the first time two inside-the-park homers are hit in the same National League game since Lou Brock and Héctor Cruz of the St. Louis Cardinals did it against the San Diego Padres on June 18, 1976. Greg Gagne of the Twins had two for Minnesota on October 4, 1986.
 * In Toronto, Roger Clemens allows one run and four hits in seven innings and strikes out seven to beat the Texas Rangers 8–1. The Rocket is now 9–0, his best start since beginning 1986 at 14–0.
 * Andrés Galarraga hits a 469-foot two-run homer and Vinny Castilla adds a solo shot as the Colorado Rockies overcome a six-run deficit to beat the St. Louis Cardinals, 9–7. Galarraga has four RBI, and his moon shot off Mark Petkovsek is the third-longest homer in the three-season history of Coors Field.
 * May 27 – Barry Larkin's streak of consecutively reaching base 13 times is stopped by Curt Schilling, who goes all the way to beat Cincinnati 2–1. Larkin singles in the first inning, but flies out in the 3rd to end his streak one shy of Pedro Guerrero's NL record, set in 1985.
 * May 30 – Baltimore Orioles pitcher Mike Mussina retires the first 25 Cleveland Indians batters before Sandy Alomar Jr. ruins his no-hit bid with a one-out single in the ninth inning. Mussina then strikes out the final two batters for a 3–0 victory.
 * May 31:
 * Cal Ripken Jr. snaps a seventh-inning tie with a record-breaking home run as the Baltimore Orioles rally from a four-run deficit to beat the Cleveland Indians, 8–5. Ripken's homer gives him 4,274 total bases with Baltimore, breaking the franchise mark for total bases in a career. Baltimore also places Eric Davis on the disabled list. Davis is suffering from colon cancer and will be operated on in early June.
 * In Miami, Andrés Galarraga golfs a 529-foot grand slam, the longest home run ever at Pro Player Stadium. His homer gives the Colorado Rockies a 7–0 lead over the Florida Marlins, and they eventually win 8–4. Galarraga has three home runs in the past three games against Florida that traveled 1,435 feet, an average of 478 feet. He hit a 455-foot homer two days before and a 451-foot homer on May 30. The longest previous homer at the stadium was 482 feet by Philadelphia Phillies' Pete Incaviglia off Al Leiter on May 1, 1996.
 * Unbeaten Roger Clemens is the first 10-game winner in the majors, as the Toronto Blue Jays romp 13–3 over the Oakland Athletics.

June–July

 * June 3 - The Florida Marlins use their first round pick to select pitcher Cliff Lee. However, Lee opts not to sign with Florida.
 * June 7 – Switch-hitter Chili Davis strokes home runs from both sides of the plate for the eleventh time in his career, to become the leader in this category. He passes Mickey Mantle and Eddie Murray, who each accomplished the feat ten times in their careers. Nick Swisher, Mark Teixeira and Carlos Beltrán will subsequently pass Davis on the list.
 * June 10 – At 3Com Park at Candlestick Point, Kevin Brown of the Florida Marlins no-hits the San Francisco Giants 9-0. He retires 23 consecutive batters before a hit-by-pitch to Marvin Benard costs him a perfect game, the only baserunner Brown will allow.
 * June 12 – The first interleague game took place as the Texas Rangers hosted the San Francisco Giants at The Ballpark in Arlington (now Choctaw Stadium). The Giants won 4-3.
 * June 24 – At the Kingdome, Randy Johnson of the Seattle Mariners strikes out 19 Oakland Athletics to tie Steve Carlton's 28-year record for most in one game by a left-handed pitcher, but loses 4-1. One of the Athletics runs comes on a towering home run by Mark McGwire, Johnson's ex-University of Southern California teammate.
 * June 28 – New York Yankees pitcher David Wells takes the mound wearing an authentic 1934 Babe Ruth cap he'd purchased for $35,000. Following a scoreless first, Manager Joe Torre makes Wells take it off because it didn't conform to uniform standards. Wells then blew a 3–0 lead, and leaves the game after three innings, having given up five earned runs. He gets a no-decision in the Cleveland Indians' 12–8 victory at Yankee Stadium.
 * June 30 – The Toronto Blue Jays host the Montreal Expos in the first game in major league baseball history between Canadian teams. The Expos won 2-1.
 * July 8 – The American League defeats the National League by a score of 3-1 in the annual All-Star Game, played at Jacobs Field. Cleveland Indians catcher Sandy Alomar Jr. hits a 2-run home run and is named the game's MVP. Alomar is the first hometown player to homer since Hank Aaron did it in Atlanta–Fulton County Stadium in 1972.
 * July 12 – At a sold out Three Rivers Stadium, Francisco Córdova pitched nine innings of a combined 10-inning no-hitter for the Pittsburgh Pirates. Ricardo Rincón pitched the 10th inning. The Pirates won the game on a dramatic three run, pinch hit home run in the bottom of the 10th by Mark Smith.
 * July 31 – Mark McGwire is traded by the Oakland Athletics to the St. Louis Cardinals for Eric Ludwick, T.J. Mathews, and Blake Stein.

August–September

 * August 8 – For the second time this season, Randy Johnson of the Seattle Mariners records a 19-strikeout performance at the Kingdome, this time against the Chicago White Sox. Unlike his 19-K performance on June 24, Johnson comes out on top, shutting out the White Sox 5-0.
 * August 24 – Sammy Sosa hits his 200th career home run helping the Chicago Cubs beat the Montreal Expos 12-3.
 * August 31 – Don Mattingly has his number 23 retired by the New York Yankees.
 * September 5 – At 3Com Park, Barry Bonds of the San Francisco Giants becomes a five-time member of the 30–30 club. Batting in the sixth inning of the Giants' 4-1 victory over the Houston Astros, Bonds, who has 32 home runs to this point, reaches first base on pitcher Shane Reynolds' error, then steals second, his 30th stolen base of the season, on a Jeff Kent strikeout. With this steal, Bonds ties his father Bobby for most seasons with both 30 home runs and 30 stolen bases.
 * September 10 – Mark McGwire joins Babe Ruth as the only players in major league history with 50 home runs in consecutive seasons by hitting a 446-foot shot off Shawn Estes in the third inning of the St. Louis Cardinals' road game against the San Francisco Giants. McGwire, who hit a major league-leading 52 homers for the Oakland Athletics last season, becomes the first player with back-to-back 50-homer seasons since Ruth did it in 1927 and 1928.
 * September 19 – Mark McGwire records his 20th home run of the season with the St. Louis Cardinals. Paired with the 34 home runs he had hit with the Oakland Athletics earlier in the year, he becomes the first player in Major League history to record twenty or more home runs for two different teams in the same season.
 * September 21:
 * Mike Piazza becomes the first Dodger in history to hit a home run completely out of Dodger Stadium. Willie Stargell of the Pittsburgh Pirates was the only previous player to accomplish this feat.
 * After going 2-for-3, Ryne Sandberg is lifted for a pinch runner in the fifth inning of an 11-3 win by the Chicago Cubs over Curt Schilling and his Philadelphia Phillies. It is Sandberg's final Major League game.
 * September 22 – At Cinergy Field, Jeff Bagwell of the Houston Astros becomes the first full-time first baseman to join the 30–30 club. After doubling off the Cincinnati Reds' Mike Remlinger to score Craig Biggio in the first inning, Bagwell, who has 42 home runs at this point, steals third base for his 30th steal of the season. He will steal another base in the game, which the Astros win 6-3. Bagwell will also join the 30–30 club in 1999.
 * September 23 – The Florida Marlins clinch the National League wild card. It is the franchise's first-ever post-season appearance.
 * September 25 – Pedro Martínez records his 300th strikeout of the season, becoming the first player since 1972 (Steve Carlton) to record 300 or more strikeouts while maintaining a sub-2.00 ERA.
 * September 28 – Tony Gwynn of the San Diego Padres ties Honus Wagner's record by winning his eighth National League batting title. Gwynn finishes at .372, becoming the first player to win four consecutive NL batting titles since Rogers Hornsby won six straight between 1920 and 1925.
 * September 30 – Tim Raines, Derek Jeter, and Paul O'Neill become the first trio to hit back-to-back-to-back home runs in a single postseason game as their New York Yankees defeat the Cleveland Indians, 8-6, in the first game of the 1997 American League Division Series.

October–December

 * October 11 – Mike Mussina sets record for most strikeouts in a postseason game for the losing team (15) as the Baltimore Orioles lose to the Cleveland Indians 2-1.
 * October 14 – The Florida Marlins become the fastest expansion team to reach the World Series with a 7-4 win over the Atlanta Braves in Game 6 of the National League Championship Series.
 * October 15 – The Cleveland Indians defeat the Baltimore Orioles 1-0 in 11 innings in Game 6 of the American League Championship Series to reach their 2nd World Series in 3 seasons.
 * October 26 – The Florida Marlins defeat the Cleveland Indians in Game 7 to win the World Series in just their 5th season of existence.
 * October 27 – The Detroit Tigers break ground on their new ballpark.
 * November 6 – The Milwaukee Brewers switch leagues, joining the National League Central Division, after the Kansas City Royals reject the invitation. With the 1998 addition of the Arizona Diamondbacks (NL) and Tampa Bay Devil Rays (AL), the move will maintain an even number of teams in each league.
 * November 12 – Ken Griffey Jr. of the Seattle Mariners becomes the ninth unanimous pick for the American League MVP Award. Griffey hit .304 for Seattle, led the AL with 56 home runs, and led the Majors with 147 RBI. He receives all 28 first-place votes and 392 points in balloting to become the first unanimous AL pick since Frank Thomas in 1993, and the 13th unanimous selection overall.
 * November 18 – The expansion draft starts with several transactions. Two pitchers who appeared in the World Series a month earlier, Tony Saunders (Florida Marlins) and Brian Anderson (Cleveland Indians), are the first players taken. Saunders, the first player chosen overall, heads a list of new Tampa Bay Devil Rays team members that includes Quinton McCracken, Bubba Trammell, Albie López and Terrell Wade. Tampa Bay also obtains John Flaherty from the San Diego Padres in exchange for Brian Boehringer and Andy Sheets; Kevin Stocker from the Philadelphia Phillies for Bobby Abreu; Fred McGriff from the Atlanta Braves in exchange for a player to be named, and signs free agent Roberto Hernández. The Arizona Diamondbacks, meanwhile, who signed free agent Jay Bell to a five-year contract the day before, selects Jeff Suppan, Jorge Fábregas and Karim García, and acquire Travis Fryman from the Detroit Tigers in exchange for Joe Randa, Gabe Alvarez and a minor leaguer. They also obtain Devon White from the Florida Marlins for a prospect.
