• February 28 – Red Schoendienst, a former second baseman and manager of the St. Louis Cardinals, and Al Barlick, a National League umpire for 28 seasons, are elected to the Hall of Fame by the Special Veterans Committee.

March 19 - The Cleveland Indians trade outfielder Mel Hall to the New York Yankees in exchange for catcher Joel Skinner and outfielder Turner Ward. March 28 - The Chicago Cubs release pitcher Goose Gossage.

• April 29 – In the first Saturday night game at Wrigley Field, the San Diego Padres and the Chicago Cubs combine to make 11 errors: 6 by the Padres, 5 by the Cubs. San Diego wins 5–4.
• April 30 - The New York Yankees trade pitcher Al Leiter to the Toronto Blue Jays in exchange for outfielder Jesse Barfield.

• May 7 – Chicago mayor Richard M. Daley presides over the groundbreaking of the new Comiskey Park.
• May 25 - In what would prove to be one of the most lopsided trades in baseball history, The Montreal Expos send pitching prospects Randy Johnson, Gene Harris, and Brian Holman to the Seattle Mariners in exchange for pitcher Mark Langston. Seattle would also send pitcher Mike Campbell to Montreal to complete the deal. Johnson would go on to a hall of fame career, whereas Langston proved to be nothing more than a rental for Montreal, as he bolted for the California Angels at the end of the season.
• May 28 – George Bell ends the Toronto Blue Jays' twelve-year stay at Exhibition Stadium with a walk-off home run to win the Jays' final game there with a 7–5 win over the Chicago White Sox, the same team the Jays' faced in their first game at Exhibition Stadium and in franchise history twelve years earlier.
• May 29 – Mike Schmidt of the Philadelphia Phillies calls a press conference and tearfully announces his retirement, effective immediately. Nonetheless, he will be voted to start the All-Star Game, and is permitted to appear in uniform.

• June 5 – Just eight days after leaving Exhibition Stadium, the Toronto Blue Jays open their new home; SkyDome (now known as Rogers Centre); the first stadium in Major League history with a functioning retractable roof. As he did in the last game at Exhibition Stadium, George Bell hits a home run.
• June 8 – At Veterans Stadium, the visiting Pittsburgh Pirates score 10 runs in the top of the first inning against the Philadelphia Phillies, three of which come on a Barry Bonds home run. As the Phillies come to bat in the bottom of the first, Pirates broadcaster Jim Rooker says on the air, "If we lose this game, I'll walk home." Both Von Hayes and Steve Jeltz hit two home runs (the latter would only hit five during his Major League career; he also becomes the first Phillie to homer from both sides of the plate in the same game) to trigger a comeback for the Phillies, who finally tie the game in the 8th on a wild pitch, then take the lead on Darren Daulton's two-run single and go on to win 15–11,^[1] becoming the first team to win a game after giving up 10 runs in the first inning. After the season, Rooker conducts a 300-plus-mile charity walk from Philadelphia to Pittsburgh.^[2]
• June 10 - The Boston Red Sox agreed to terms with their number one pick in the 1989 draft, first baseman Jeff Bagwell.
• June 18 - The New York Mets traded outfielder Lenny Dykstra and pitcher Roger McDowell and a player to be named later to the Philadelphia Phillies in exchange for outfielder Juan Samuel. On July 27th, the Mets would send pitcher Tom Edens to the Phillies to complete the deal.
• June 21 - The New York Yankees trade outfielder Rickey Henderson back to the Oakland Athletics in exchange for pitchers Eric Plunk, Greg Cadaret and outfielder Luis Polonia.

• July 1 - Days after he's released by the New York Yankees, Richard Dotson agrees to a deal with the Chicago White Sox, returning to the team he played for before joining the Yankees.
• July 4 – Against the Philadelphia Phillies at Veterans Stadium, Cincinnati Reds pitcher Tom Browning, having already pitched a perfect game a year earlier, misses becoming the first pitcher in Major League history to throw two perfect games. Dickie Thon's leadoff double in the ninth breaks up this bid; Thon later scores on a Steve Jeltz single. John Franco then relieves Browning and induces Lenny Dykstra to hit into a game-ending double play for a Reds 2–1 victory.
• July 5:
  • Mark McGwire hits his 100th career home run.
  • Cincinnati Reds outfielder Paul O'Neill kicks a ball to the infield to prevent Steve Jeltz of the Philadelphia Phillies from scoring the game winning run. Moments later Jeltz scores the winning run on a wild pitch as the Phillies defeat the Reds 3-2.
• July 11 – At Anaheim Stadium, Bo Jackson and Wade Boggs lead off the bottom of the first inning with back-to-back home runs off Rick Reuschel to spark the American League to a 5–3 win over the National League in the All-Star Game. Jackson earns MVP honors.
• July 13:
  • A game between the Montreal Expos and Los Angeles Dodgers at Olympic Stadium is rained out because the roof, ripped by 62 mile per hour winds on June 27, cannot be lowered from its retracted position. Zamboni machines were used in an attempt to remove the water.
  • After missing just over half the season with a broken wrist, Jose Canseco returns to the Oakland A's lineup, homers, and drives in three runs in his first game back, an 11–7 win over the Toronto Blue Jays.
• July 14 – At Atlanta-Fulton County Stadium, the New York Mets' Sid Fernandez enters the bottom of the ninth against the Atlanta Braves with 16 strikeouts, but then the Braves' Lonnie Smith hits a walkoff solo home run on Fernandez' second pitch to give the Braves a 3-2 victory.
• July 16 – California Angels manager Doug Rader is ejected before the game against the Baltimore Orioles while taking the lineup card to home plate for arguing Mike Devereaux's disputed game-ending home run (fair vs. foul) from the night before.
• July 29 – At Olympic Stadium, Vince Coleman of the St. Louis Cardinals is called out twice for interference on the base paths.
  • The Texas Rangers make a trade with the Chicago White Sox, sending fan favorite Scott Fletcher, along with pitcher Wilson Alvarez and a young outfielder named Sammy Sosa to Chicago in exchange for outfielder Harold Baines and infielder Fred Manrique.

• August 3 – The Cincinnati Reds score 14 first inning runs in an 18–2 rout of the Houston Astros, just missing the major league record of 15, which ironically was set against the Reds by the Brooklyn Dodgers in 1952.
• August 4 – Dave Stieb, pitching for the Toronto Blue Jays, loses a perfect game with two outs in the ninth inning when Roberto Kelly doubles, and later scores. Stieb wins a 2–1 two-hitter, but it is the third no-hitter that he has lost in the ninth inning in the past 11 months.
• August 10:
  • A little over 10 months removed from surgery to remove a cancerous tumor from his pitching arm, Dave Dravecky of the San Francisco Giants starts and beats the Cincinnati Reds 4–3, pitching eight innings.
  • For the fifth time in his career, five-time no-hit pitcher Nolan Ryan has a no-hitter broken up in the ninth. His Texas Rangers leading the Detroit Tigers 4–0 at Arlington Stadium, Ryan has the bid broken up by a Dave Bergman single with one out. After Matt Nokes doubles home Bergman, Ryan is relieved by Jeff Russell, who retires the two batters he faces, striking out Doug Strange for the final out. Ryan had four other no-hit bids broken up in the ninth in 1974, 1979, 1988, as well as April 23 of this season; coincidentally, all four had also been broken up with one out in the ninth. Ryan will go on to pitch two more no-hitters, in 1990 and 1991.
• August 15 – After his miraculous comeback game against the Reds, Dave Dravecky starts against the Montreal Expos and, in the sixth inning, the humerus bone in his pitching arm snaps, ending his season. While celebrating the Giants' clinching the NL West division title, Dravecky would break the arm once again. Doctors would later discover that the cancer in his arm had returned. Eighteen days later, Dravecky would retire from baseball.
• August 17 – Bruce Hurst of the San Diego Padres becomes the first pitcher in Major League history to defeat both reigning Cy Young Award winners in the same season. In the Padres' 6–2 victory over the New York Mets at Shea Stadium, he bests Frank Viola, who had been traded from the Minnesota Twins after winning the American League Cy Young Award. On July 28, Hurst had defeated the Los Angeles Dodgers and National League Cy Young winner Orel Hershiser 2–1 at Jack Murphy Stadium.
• August 21 – Cal Ripken hits his 200th career home run, helping the Baltimore Orioles beat the Milwaukee Brewers 5–0.
• August 22 – Nolan Ryan records his 5000th strikeout of Rickey Henderson in the 3rd inning of a complete game effort for Ryan. The visiting Oakland Athletics would shut out the Texas Rangers by a score of 2-0.
• August 23 – The Los Angeles Dodgers edge the Montreal Expos 1–0 in 22 innings, the longest game in Expos franchise history. During the game, Expos mascot Youppi! is ejected by umpire Bob Davidson after manager Tommy Lasorda complains that the furry creature is pounding on the top of the dugout. Rick Dempsey hit a solo home run off of Dennis Martínez for the game's winning and only run.
• August 24 – Commissioner A. Bartlett Giamatti announces in a press conference that Pete Rose is banned from baseball for life, in the wake of evidence that has come to light regarding Rose's alleged gambling history.

• September 1 – Commissioner A. Bartlett Giamatti unexpectedly dies of a heart attack.
• September 13 – Fay Vincent is officially named the new Commissioner of Baseball following the death of A. Bartlett Giamatti.
• September 14 – Jeff Reardon of the Minnesota Twins earns his 30th save of the season in a 2–0 win over the Toronto Blue Jays. He becomes the first pitcher to save 30 games in five consecutive seasons.
• September 26 - At Olympic Stadium in Montreal, the Boys of Zimmer reached its peak as the Chicago Cubs beat the Montreal Expos 3-2 to win their second National League East title in the 1980s.
• September 30 – NBC broadcasts its final Major League Baseball Game of the Week (before the program is transferred to CBS). NBC had broadcast the Game of the Week since 1957 and exclusively since 1966. Bob Costas and Tony Kubek called the action from Toronto's SkyDome, as the Toronto Blue Jays defeated the Baltimore Orioles to clinch the American League Eastern Division title.

• October 3 – Kirby Puckett wins an unlikely, at the time, batting title taking advantage of an off year by Wade Boggs due to marital issues. Puckett would clinch the title in Seattle on a double in the final game of the season.
• October 9 – After 43 years on the air, NBC concludes its run (coinciding with the San Francisco Giants defeating the Chicago Cubs in Game 5 of the National League Championship Series to insure their first trip to the World Series since 1962) as the number one over-the-air network television broadcaster for Major League Baseball games.
• October 17 – Game 3 of the World Series is postponed due to the Loma Prieta earthquake, which struck immediately before the game was set to begin. It would be rescheduled for ten days later, October 27.
• October 28 – The Oakland Athletics complete a four-game sweep of the San Francisco Giants in the 1989 World Series. It's the first WS sweep since 1976. Oakland pitcher Dave Stewart, who won two games, is named MVP. It is also the latest in the calendar year that a World Series game has ever been played up to this point. This was also ABC's final Major League Baseball telecast until July 1994, when The Baseball Network was launched. ABC, who had broadcast Major League Baseball games since 1976 was like NBC was about to lose the television rights to CBS.

• November 1 – Frank Robinson who led the Baltimore Orioles to a near American League East Title was named American League Manager of the Year by the Baseball Writers Association of America. He received 23 of 28 first place votes.
• November 20 – Milwaukee Brewers outfielder Robin Yount wins his second American League MVP Award. With his 1982 Award coming in a year he played shortstop, he is the second player (Hank Greenberg) to win two such awards while playing different positions.
• November 21 – Kevin Mitchell who batted .291 and scored 100 runs and led the San Francisco Giants to their first World Series appearance since 1962 was named the National League MVP. Mitchell received 20 of the 24 first-place votes.
