- January 5 - Don Sutton, a 324-game winner, is elected to the Baseball Hall of Fame on his fifth try. Sutton, who missed election by nine votes in 1990, is named on 81.6% of the ballots.
- February 2 - New York Yankees general manager Bob Watson announces his resignation. He is replaced by 30–year–old Brian Cashman.
- March 3 - Larry Doby, Lee MacPhail, George Davis and Bullet Joe Rogan are elected to the Hall of Fame by the Veterans Committee.
- March 31 - The Tampa Bay Devil Rays lose to the Detroit Tigers 11–6, in their first game ever. Pitcher Wilson Alvarez takes the loss for Tampa while third baseman Wade Boggs hit the first home run in team history and drives in three runs.
- March 31 - The Arizona Diamondbacks drop a 9–2 decision to the Colorado Rockies in their first game ever. Andy Benes is tagged with the loss, and rookies Travis Lee, who gets three hits, and Karim García hit home runs. Vinny Castilla drives in five runs for Colorado.
- April 1 - The expansion Tampa Bay Devil Rays win their first game in franchise history, beating the Tigers 11–8. Fred McGriff has four RBI on three hits.
- April 2 - By hitting a home run in Colorado's 6–4 win over Arizona at Bank One Ballpark, Rockies outfielder Ellis Burks sets a major league record by having homered in 33 different stadiums.
- April 5 - The Arizona Diamondbacks win their first game in franchise history 3–2, over the San Francisco Giants. Andy Benes gets the win for the 1–5 D'backs.
- April 10 - The Los Angeles Dodgers' Mike Piazza becomes the fifth NL player in history to hit grand slams in consecutive games by homering in a 7–2 win over the Houston Astros. Piazza also homered with the bags full, while driving in six runs, in last night's 7–2 win over Arizona. He'll hit another on April 24 to tie the major-league record for slams in a month.
- April 13 - The Seattle Mariners' Ken Griffey, Jr. slugs two home runs in a 6–5 loss to the Cleveland Indians. In doing so, he becomes the second–youngest player in big league history to reach 300 homers for his career, at 28 years and 143 days. Jimmie Foxx, at 27 years 328 days, was younger.
- May 3 - The Seattle Mariners' Dan Wilson becomes just the seventh catcher in major league history to hit an inside-the-park grand slam, as Seattle defeats Detroit 10–6. It's a first for the Mariners and the first in the AL since Mike Greenwell did it on September 1, 1990.
- May 6 - In one of the finest pitching efforts ever, Chicago Cubs rookie righthander Kerry Wood fans 20 Houston Astros in a 2–0, one-hit victory to tie the major league mark for strikeouts in a 9-inning game. The 20-year-old ties the record held by Roger Clemens, who performed the feat twice. Wood does not walk a batter in his masterpiece, allowing only an infield single to Ricky Gutiérrez in the 3rd inning, that likely would have been ruled an error had it occurred late in the game. He hit one batter with a pitch, for only two Astros baserunners allowed. Wood also becomes the second pitcher in baseball history whose strikeout total matches his age (Bob Feller struck out 17 at the same age). Wood strikes out the first five batters of the game, and seven in a row between the 7th and 9th innings, a streak that ties Jamie Moyer's Cubs record. He'll strike out 13 Diamondbacks in just seven innings of a 4–2 win over Arizona in May 11. By doing so, Wood sets a major league record with 33 strikeouts over two consecutive games.
- May 13 - The Atlanta Braves set an NL record by homering in their 25th straight game, a 10–2 win over the St. Louis Cardinals. This ties the major league mark held by the 1941 Yankees and the 1994 Tigers. The streak will be stopped by the Cardinals tomorrow.
- May 15 - In one of the biggest trades in recent years, the Dodgers send All-Star catcher Mike Piazza and third baseman Todd Zeile to the Florida Marlins in exchange for outfielders Gary Sheffield and Jim Eisenreich, catcher Charles Johnson, third baseman Bobby Bonilla, and pitcher Manuel Barrios. On May 22, the Mets will acquire Piazza from the Marlins in exchange for outfielder Preston Wilson, pitcher Ed Yarnall and a minor league player.
- May 17 - Yankees pitcher David Wells hurls the 13th perfect game in modern major league history with a 4–0 win over the Minnesota Twins. Wells fans 11 batters in his masterpiece. Bernie Williams strokes three hits for New York, including a home run.
- May 18 - The Oakland Athletics' Mike Blowers hits for the cycle and drives home four runs in the A's 14–0 win over the White Sox. Blowers become only the 2nd player in franchise history to accomplish the feat.
- May 19 - The Cardinals' Mark McGwire hits three home runs in a game for the 2nd time this season, leading St. Louis to a 10–8 victory over the Philadelphia Phillies. He is only the 12th player in history to have a pair of 3–HR games in the same season. McGwire drives in six of the Cardinal runs as he reaches the 20 home run mark faster than other player in history.
- May 20 - The Triple-A Indianapolis Indians perform a feat possibly never before duplicated in professional baseball. In the 5th inning of a game against the Pawtucket Red Sox, Indianapolis players hit for a "Homer Cycle". Pete Rose, Jr. opens the inning with a solo home run, Jason Williams connects for a 3–run shot, Glenn Murray slugs a grand slam, and Guillermo Garcia finishes the scoring with a 2–run blast. The Indians win the game 11–4.
- May 25 - Cleveland's David Bell becomes the third player in major league history to play against a team managed by his father. Bell's 2–run double brings home the go–ahead run in the Indians 7–4 win over Buddy Bell's Detroit Tigers. Bump Wills and Moisés Alou are the only other players to appear in games against their fathers (Maury Wills and Felipe Alou).
- May 28 - With Arizona leading the Giants, 8–6, in the bottom of the 9th with the bases loaded, manager Buck Showalter orders reliever Gregg Olson to intentionally walk Barry Bonds to bring home the Giants' 7th run. It is only the 4th bases–loaded intentional walk in major league history, and the first since Bill "Swish" Nicholson on July 23, 1944.
- June 6 - Hall of Fame second baseman Joe Morgan has his uniform number 8 retired by the Cincinnati Reds in a ceremony at Cinergy Field.

- August 13 - Harold Baines of the Baltimore Orioles becomes the all–time leader in RBI by a designated hitter when he drives in his 824th in a 7–4 win over the Indians. Hal McRae was the previous record–holder.

- August 31 - Oakland's Rickey Henderson scores the 2,000th run of his career in the Athletics' 15–6 loss to Cleveland. He joins Ty Cobb, Hank Aaron, Babe Ruth, Pete Rose and Willie Mays as the only players to reach the milestone.

- September 8 - Mark McGwire breaks Roger Maris' 37-year-old home run record, lining historic No. 62 just over the wall in left field with two outs in the fourth inning. McGwire's shot off the Chicago Cubs' Steve Trachsel sets off a wild celebration at Busch Stadium.

He becomes the 4th–youngest player in history to reach the milestone, after Mel Ott, Jimmie Foxx and Lou Gehrig. A day later, Griffey will collect his 20th stolen base of the season to become just the third player in major league history to record at least 50 homers and 20 steals in the same season; Willie Mays and Brady Anderson are the others.
- September 17 - Denny Neagle puts the Atlanta Braves pitching staff into the baseball record books as he limits the Arizona Diamondbacks to four hits in six innings for a 1-0 win.

Neagle joins Tom Glavine, Greg Maddux, John Smoltz and Kevin Millwood.
- September 20 - Cal Ripken, Jr. of the Baltimore Orioles takes himself out of the lineup prior to the game with the New York Yankees to end his major league record consecutive game streak at 2,632.
