February 15 – A thirty-two-day lockout begins as Major League Baseball owners refuse to open spring training camp without reaching a new Basic Agreement with the players. The regular season is delayed one week due to the lock-out.

It is Langston's first start for the Angels since signing as a free agent in the off-season. Angels first baseman Wally Joyner makes an error in the fitth inning when he overthrows Langston on Pete O'Brien's grounder. O'Brien tries for second base‚ not realizing that catcher Lance Parrish backs up the play, and he is out.
April 20
Pete Rose pleads guilty to two charges of filing false income tax returns not showing income he receives from selling autographs, memorabilia, and from horse racing winnings.
After retiring the first 26 Oakland Athletics batters, Brian Holman loses a perfect game when Ken Phelps hits a home run in an eventual 6–1 Seattle Mariners win.
May 22 – Andre Dawson of the Chicago Cubs is intentionally walked by Cincinnati Reds' pitching five times; the first player to do so in Major League history.
June 2 – At the Kingdome, Randy Johnson of the Seattle Mariners no-hits the Detroit Tigers 2-0. The no-hitter is the first in both Mariner and Kingdome history.
June 6 – The highest-profile managerial firing of 1990 season happens when the New York Yankees fire Bucky Dent before a game against their rivals at Fenway Park, where he hit his famous three-run home run in a one-game playoff game in 1978, making Fenway Park the scene of his greatest moment as a player and worst moment as manager.
June 11 – Nolan Ryan pitches the sixth no hitter of his career by defeating the Oakland Athletics in Oakland, 5-0.
June 14 – It is announced that the National League expands by two teams for the 1993 season.
June 29 – For the first time in major league history, two no-hitters are thrown on the same day in both leagues. Dave Stewart for the Oakland Athletics, no-hits his future team, the Toronto Blue Jays, at SkyDome. Hours later, Dodger pitcher Fernando Valenzuela no-hit the St. Louis Cardinals at Dodger Stadium.
July 1 – While no longer recognized as such, the New York Yankees' Andy Hawkins pitches a no hitter at old Comiskey Park. However, walks and errors lead to four unearned runs as the Chicago White Sox win 4-0. Hawkins pitches for the visiting team, and pitches only 8 innings since there is no bottom of the 9th.
July 5 – Whitey Herzog quits in his eleventh year as manager of the St. Louis Cardinals. He has a 1,281-1,125 (.532) record in 18 years as a manager, including stints with the Texas Rangers, California Angels and Kansas City Royals..
July 10 – Six American League pitchers combine for a two-hitter and a 2–0 victory over the National League in a rain-delayed All-Star Game at Wrigley Field. Texas Rangers second baseman Julio Franco drives in both runs in the 7th inning and is named MVP.
July 12 – Barry Bonds hits his 100th career home run.
July 12 – Mélido Pérez of the Chicago White Sox no-hits the New York Yankees at Yankee Stadium 8-0. However, the game is called after six innings by rain. Perez's no-hitter avenges Andy Hawkins no-no back on July 1; coincidentally, Hawkins is the losing pitcher for New York in Perez's game.
July 17 – The Minnesota Twins turn two triple plays in a single game – the first time that's been accomplished in the major leagues – against the Boston Red Sox, yet still lose the game 1–0 on an unearned run. The following night, the two clubs tie a major league record by turning a combined ten double plays in their game, another Boston victory. Boston ties an American League record by grounding into six double plays in the nine-inning game.
July 19 – Pete Rose is sentenced to five months in the medium security Prison Camp at the United States Penitentiary in Marion, Illinois and fined $50,000 following his April 20 guilty plea to two charges of filing false income tax returns not showing income he receives from selling autographs, memorabilia, and from horse racing winnings.
July 31 – Nolan Ryan of the Texas Rangers earns his 300th career win, against the Milwaukee Brewers.
August 3 – Against the Philadelphia Phillies at Veterans Stadium, Doug Drabek of the Pittsburgh Pirates has a no-hitter broken up with two out in the ninth. Sil Campusano, who had not even been in the starting lineup, breaks up the bid with a single to right; the hit is the only one Drabek will allow in the Pirates' 11-0 victory. The no-hitter would have been the Pirates' first since John Candelaria in 1976.
August 15 – At Veterans Stadium, Terry Mulholland of the Philadelphia Phillies no-hits the San Francisco Giants 6-0.
August 25 – In the fourth inning of a 14-4 victory over the Oakland Athletics at Tiger Stadium, Cecil Fielder of the Detroit Tigers, batting against Dave Stewart, hits a home run that clears the left-field roof. The home run is the third overall, and the first by a Tiger, to clear the left-field roof. Harmon Killebrew hits a home run over the roof in 1962 and Frank Howard in 1968.
August 27 – At Cleveland Stadium, Boston Red Sox outfielder Ellis Burks hit two home runs in an eight-run 4th inning of a 12–4 victory over the Indians. It is only the second time a Red Sox hitter homers twice in an inning. Bill Regan is the first, on June 16, 1928.
August 31 – Ken Griffey and his son Ken Griffey, Jr. start for the Seattle Mariners in a game against the Kansas City Royals. It marks the first time a father and son ever play in the same Major League game.
September 2 – After coming close on numerous occasions, Dave Stieb of the Toronto Blue Jays hurls his team's first (and so far only) no-hitter, blanking the Cleveland Indians 3-0 at Cleveland Stadium.
September 3 – Reliever Bobby Thigpen sets a major league record with his 47th save in a 4–2 Chicago White Sox victory over the Kansas City Royals. The previous record was set by Dave Righetti of the New York Yankees in 1986.
September 14 – Ken Griffey and Ken Griffey, Jr. hit back-to-back home runs in a 7-5 loss to the California Angels. Pitcher Kirk McCaskill gives up the historic home runs.
September 15 – Bobby Thigpen of the Chicago White Sox saves his fiftieth game, becoming the first pitcher to reach that mark. The White Sox defeat the Boston Red Sox 7-5.
September 19 – At Wrigley Field, Barry Bonds of the Pittsburgh Pirates becomes a first-time member of the 30–30 club. Batting in the fifth inning of the Pirates' 8-7 victory over the Chicago Cubs, Bonds, who had stolen his 49th base earlier in the game, hits his 30th home run off Cub pitcher Bill Long. Bonds will go on to tie his father Bobby for most 30 home run/30 stolen base seasons with five.
September 22 – Andre Dawson of the Chicago Cubs steals his 300th base in an 11–5 loss to the New York Mets, becoming only the second player in major league history with 300 home runs, 300 steals and 2,000 hits; Willie Mays is the first, though they are later joined by Barry Bonds.
September 29 – While waiting through a rain delay, the Cincinnati Reds watch the Los Angeles Dodgers lose to the San Francisco Giants 4-3, which clinches the National League West Division for the Reds. The Reds are the first National League team to lead their division wire-to-wire since the inception of the 162-game season.
September 30 – Harold Reynolds of the Seattle Mariners grounds out; shortstop Scott Fletcher to first baseman Steve Lyons, giving the Chicago White Sox a 2-1 victory in the final game to ever be played at historic Comiskey Park. Bobby Thigpen is on the mound to earn his 57th save, establishing a Major League record for saves in a season.
October 20: The talk of an Oakland Athletics dynasty is proven premature, as the Cincinnati Reds beat Oakland 2–1 to complete one of the most stunning sweeps in World Series history. Series MVP José Rijo (2–0, 0.59 ERA) retires the last 20 batters he faces to give the Reds their first World Championship since 1976. Not joining the celebration at the end is Eric Davis, who ruptures his kidney diving for a ball during the game and is taken to the hospital. It takes Davis several years to fully recover.
November 23 – former Philadelphia Phillies and Cincinnati Reds catcher Baudilio (Bo) Díaz, 37, is crushed to death when a rooftop satellite dish topples over at his home in Venezuela.
December 5 – In a blockbuster deal, the Toronto Blue Jays send Tony Fernandez and Fred McGriff to the San Diego Padres for Roberto Alomar and Joe Carter.
December 6: At Herman Darvick Autograph Auctions in New York City, Shoeless Joe Jackson's signature is sold for $23,100, the most money ever paid for a 19th- or 20th-century signature.
