January

 * January 10 – Luis Aparicio, Don Drysdale and Harmon Killebrew are elected to the Hall of Fame by the Baseball Writers' Association of America.

 * Continuing his attempt to chase Ty Cobb's all-time hits record, Pete Rose signs with the Montreal Expos.

February

 * February 8 - The Oakland Athletics make use of an obscure loophole to select pitcher Tim Belcher from the New York Yankees as a free agent compensation pick. Belcher had just been drafted by the Yankees earlier that year in the free agent draft. Because the Yankees mistakenly thought he wasn't eligible to be drafted, they didn't need to protect him. The matter went to an arbitrator who ruled in favor of Oakland.
 * February 17 - The Houston Astros signed J.R. Richard. Richard was attempting to make a comeback after complications from a stroke ended his career years earlier. Richard was not successful in his comeback attempt.
 * February 21 - Dusty Baker is granted free agency by the Los Angeles Dodgers.

 * Jack Morris of the Detroit Tigers no-hits the Chicago White Sox 4–0 at Comiskey Park, in a game televised on NBC. The no-hitter is the first no-hitter by a Tiger since Jim Bunning in 1958 and also ties Ken Forsch's in 1979 as the earliest, calendar-wise, that a no-hitter is pitched.
 * The New York Mets' Dwight Gooden strikes out five in five innings to earn his first major league win, 3–2 over the Houston Astros.
 * April 10 - Ruppert Jones signs with the Detroit Tigers as a free agent. Jones played the previous season with the San Diego Padres, whom the Tigers would go on to face in the World Series.

 * April 22 – For the second day in a row, the Philadelphia Phillies put up twelve runs against the New York Mets, assuming first place in the National League East.

 * May 8 – May 9 – The Chicago White Sox and Milwaukee Brewers face off in a game that started on the 8th, the game is suspended after a 3–3 tie and seventeen innings. When the game is resumed the next day, both teams manage to score three runs in the 21st inning, and is only ended when Harold Baines slams a home run in the bottom of the 25th inning to end the 8 hour, six minute marathon; the longest game, by time, in Major League history.  Tom Seaver, the last pitcher available for the White Sox, earns the win, and then goes on to start the regularly scheduled game that day, earning a second win on one day for a starting pitcher.
 * May 9 – After Mets pitching allows 31 runs in the previous three games, Ron Darling, Doug Sisk and Jesse Orosco combine to hold the Atlanta Braves to just one run at Shea Stadium.
 * May 11 – Dwight Gooden out duels Fernando Valenzuela as the New York Mets defeat the Los Angeles Dodgers 2–0 at Dodger Stadium. Valenzuela strikes out eight in eight innings, while Gooden strikes out eleven in a complete game.
 * May 12 – In defeating the St. Louis Cardinals 2–1 at Riverfront Stadium, Mario Soto of the Cincinnati Reds has a no-hitter broken up with two out in the ninth as George Hendrick's solo home run ties the game at 1–1. It is the only hit Soto allows. The Reds win the game for Soto in the bottom of the ninth, as Brad Gulden singles in Dave Concepción, the winning run.
 * May 16 – Mike Schmidt hit his 400th home run and Len Matuszek drove in four runs to lead The Philadelphia Phillies to a 12–1 win over The Los Angeles Dodgers. Schmidt became the 20th player to hit 400 home runs as Jerry Koosman the winning pitcher beat the Dodgers for the first time Since 1975 when Koosman was pitching for the New York Mets.
 * May 17 - Jim Palmer's major league career comes to an end, as he is released by the Baltimore Orioles.
 * May 24 – The Detroit Tigers' Jack Morris pitches a four hit complete game victory against the California Angels to improve his record to 9–1, and the team's record to 35–5, the best 40-game start in major league history.
 * May 27 – As the Cincinnati Reds played the Chicago Cubs at Wrigley Field, Cubs third baseman Ron Cey hit a long foul ball down the left field line, but third base umpire Steve Rippley incorrectly ruled it a home run. Reds pitcher Mario Soto shoves Rippley during an argument over the call. After conferring, the umpires change their decision and rule it a foul ball. However, for shoving Rippley, Soto is ejected, prompting him to charge the field and attack Cubs third base coach Don Zimmer, which triggers a ten-minute bench-clearing brawl. The Reds win the game, completing a three-game sweep of the Cubs. Four days later, National League president Chub Feeney suspends Soto five games for the incident.

June

 * June 7 - Bucky Dent makes his return to New York as he signs a contract with the New York Yankees.

 * June 13 – Rick Sutcliffe, George Frazier and Ron Hassey are traded by the Cleveland Indians to the Chicago Cubs, in exchange for Joe Carter, Mel Hall, Don Schulze and Darryl Banks. Sutcliffe becomes the ace of the Cubs' staff, making 20 starts and winning 16 of 17 decisions with a 2.69 ERA.
 * June 16 – Leading off the fifth inning, Cincinnati Reds pitcher Mario Soto throws several brushback pitches at Atlanta Braves slugger Claudell Washington, who had homered in his last at-bat. Washington tosses his bat in the direction of Soto and tries to go out to retrieve it, but instead walks toward the mound. The chief umpire and Reds infielder Lenny Harris attempts to restrain Washington, but he is thrown to the ground. Soto uses the distraction to punch Washington. Several of Washington's teammates attempt to hold Washington to the ground. While they are doing that, Soto fires the baseball into the crowd of players, striking Braves coach Joe Pignatano. Soto is suspended three games for this incident while Washington receives a five-game suspension for shoving Harris.
 * June 19 – In his first start since being acquired from the Cleveland Indians, Rick Sutcliffe pitches into the ninth inning against the Pittsburgh Pirates at Three Rivers Stadium without allowing a run. Sutcliffe is lifted in the ninth after giving up one earned run and is charged with two more unearned runs after Lee Smith replaces him on the mound. Even though, the Cubs hold on for the 4–3 victory.
 * June 23 – At Wrigley Field, the Chicago Cubs and rival St. Louis Cardinals locked up in what would be a tight game. In the bottom of the ninth inning, trailing 9–8, Cubs second baseman Ryne Sandberg hit a solo-home run off reliever Bruce Sutter. The Cardinals regained the lead in the tenth inning, 11–9, but Sandberg hit another home run against Sutter in the bottom of the frame, this time with one runner on base and two outs. In a lost cause, St. Louis outfielder Willie McGee would hit for the cycle, as the Cubs went on to win the game 12–11 in the following inning and eventually won the National League East title. Sandberg earned the MVP Award this season, with this game as a key contribution.
 * June 26 - At Wrigley Field, Jason Thompson of the Pittsburgh Pirates ties Ralph Kiner's 37-year franchise record by hitting four home runs in a doubleheader against the Chicago Cubs. He hits two home runs in both games, the Pirates winning the first game 9-0, and the Cubs the nightcap 9-8.

After Valenzuela whiffs Dave Winfield, Reggie Jackson and George Brett in the 4th inning, Gooden, the youngest All-Star ever at age 19, fans Lance Parrish, Chet Lemon and Alvin Davis in the 5th inning.
