Major league baseball final standings
- January 10 – Luis Aparicio, Don Drysdale and Harmon Killebrew are elected to the Hall of Fame by the Baseball Writers' Association of America.
- January 20 – Believing that it is unnecessary to protect a 39-year-old pitcher, the New York Mets leave Tom Seaver unprotected, and he is chosen by the Chicago White Sox from the Mets as a free agent compensation pick.
- April 7 :
- 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 13 – Twenty-one years to the day that he collects his first Major League hit, Pete Rose collects the 4,000th hit of his career; he is only the second player (after Ty Cobb) to ever do so.
- 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.
- April 27 – After nineteen innings, two Glenn Abbott errors followed by a Kirk Gibson error in right field lead to four unearned runs for the Cleveland Indians, who beat Detroit 8-4 at Tiger Stadium.
- April 29 – Jerry Koosman steps on the mound at Shea Stadium for the first time in his career against the New York Mets. The Mets beat Koosman and the Philadelphia Phillies, 6-2.
- May 4 – Dave Kingman of the Oakland Athletics pops a ball up that never comes down. Playing the Minnesota Twins at the Metrodome, Kingman's pop fly goes through the roof of the stadium.
- May 8 – Hall of Famer Kirby Puckett makes his major league debut, going 4 for 5 as his Minnesota Twins shut out California, Puckett will collect 2300 more hits before retiring prematurely in 1996 due to vision problems in his left eye.
- 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 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 9 – A 12–2 victory over the Cincinnati Reds coupled with an Atlanta Braves loss give the San Diego Padres their first division lead in the National League West since May 28. The Padres do not relinquish their division lead for the remainder of the season.

- 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.
