Major league baseball final standings
- The asterisk denotes the club that won the wild card for its respective league.
- January 6 – Dennis Eckersley and Paul Molitor are elected to the National Baseball Hall of Fame by the BBWAA in their first year of eligibility. Eckersley, who spent a 24-year career with the Cleveland Indians, Boston Red Sox, Chicago Cubs, Oakland Athletics and St. Louis Cardinals, is one of only a few pitchers to excel as both a starter and a closer, becoming the only pitcher in Major League history to collect 100 complete games and 100 saves, while posting ten or more wins 10 times, including a 20-win season, a no-hitter in 1977, and winning the American League MVP and Cy Young Awards in 1992. A versatile player, able to cover positions across infield and outfield, Molitor is only the third player with at least 3,000 hits 600 doubles and 500 stolen bases, being the others Ty Cobb and Honus Wagner. Besides, Molitor collected seven consecutive hits with the Milwaukee Brewers in the 1982 World Series, including the first five-hit game ever in a Series. At the age of 37, after signing with the Toronto Blue Jays, Molitor collected 111 RBI, becoming the oldest player in Major League history to post his first 100-RBI season. Then when Toronto defeated the Philadelphia Phillies in six games in the 1993 World Series, he was named MVP after hitting a .500 average (12-for-24) with two home runs and eighth RBI, while tying a Series record with 10 runs scored.
- January 12 – Roger Clemens signs a contract with the Houston Astros, ending his retirement after the 2003 season.
- February 15 – Alex Rodriguez is traded by the Texas Rangers to the New York Yankees in exchange for Alfonso Soriano and a player to be named later.
- March 4 – Commissioner Bud Selig announces that Major League Baseball will celebrate Jackie Robinson Day in every ballpark on April 15, commemorating and honoring the anniversary of the debut of Jackie Robinson, who became the first black major league baseball player of the modern era in the 1947 season. Previously, Robinson's uniform number "42" was retired for all time in a ceremony at Shea Stadium in April 1997 to mark the 50th anniversary of his achievement. His debut with the Brooklyn Dodgers ended approximately 80 years of baseball segregation, also known as the baseball color line.
- March 21 – Veterans Stadium, home of the Philadelphia Phillies from 1971 to 2003, is demolished in a 62-second implosion. It hosted the Philadelphia Phillies of Major League Baseball from 1971 to 2003 and the Philadelphia Eagles of the National Football League from 1971 to January 2003. Likewise, the 1976 and 1996 Major League Baseball All-Star Games were held at the venue, and the Vet also hosted the annual Army-Navy football game seventeen times between 1980 and 2001.
- April 8 – In the first-ever regular-season game at San Diego's Petco Park, the San Diego Padres defeat the San Francisco Giants, 4-3, in ten innings.

- April 14 – At Yankee Stadium, Kevin Brown of the New York Yankees wins his 200th career game, the Yankees defeating the Tampa Bay Devil Rays 5-1. Brown's victory follows teammate Mike Mussina's 200th career victory in the team's most recent game three days earlier, the Yankees having defeated the Chicago White Sox 5-4. The Yankees become the first team to have two pitchers record their 200th career victories in the same season, and their duo reaches their milestones in consecutive games.
- April 18 – At Wrigley Field, Sammy Sosa sets the record for most home runs in a Chicago Cub uniform. In the first inning of the Cubs' 11-10, 10-inning loss to the Cincinnati Reds, Sosa, who entered the game tied with Ernie Banks with 512 home runs as a Cub, homers off Paul Wilson; he will hit another home run off Wilson in the third inning. At the end of the season, Sosa will be traded to the Baltimore Orioles, after hitting 545 home runs as a Cub.
- April 27 – Chad Moeller becomes the fifth Milwaukee Brewers player to hit for the cycle, the first to do it at home, and the first since Paul Molitor did it on May 15, 1991 against the Minnesota Twins.
- May 8 – At Fenway Park, Pokey Reese has the first two-homer game of his career in the Boston Red Sox' 9-1 victory over the Kansas City Royals. Curt Schilling pitches his first AL complete game, and the 80th of his career, while striking out eight. Reese hits an inside-the-park home run and one of the conventional type over the Green Monster, to snap a 172 at-bat homerless streak dating to April 4, 2003. The last Red Sox player to hit a conventional homer and an inside-the-park homer in the same game was Tony Armas on September 24, 1983, at Tiger Stadium.
- May 12 – In one of the most remarkable at-bats in major league history, Alex Cora fouls off 14 consecutive pitches and then hits the 18th pitch over the right field fence for a two-run home run off Chicago Cubs pitcher Matt Clement. The homer extends the Los Angeles Dodgers lead to 4-0. The Dodger Stadium crowd cheers each foul ball as the total starts to be displayed on the scoreboard.
- May 18 – Arizona Diamondbacks pitcher Randy Johnson becomes only the 17th person in major league history to throw a perfect game, throwing 13 strikeouts on his way to a 2-0 defeat of the Atlanta Braves.
- May 26 – The Pittsburgh Pirates' Daryle Ward hits for the cycle in the Pirates' 11-8 victory over the St. Louis Cardinals. It is done 23 times in Pittsburgh history and 243 times in the majors since 1882. Ward joins his father, Gary Ward, to become the first father-son combination in major league history to hit for the cycle. The senior Ward accomplished the feat on September 18, 1980, for the Minnesota Twins.
- May 28 – Mariano Rivera notches his 300th career save in the New York Yankees' 7-5 victory over the Tampa Bay Devil Rays. He also becomes the first Yankee and 17th reliever in major league history to reach the milestone.
- May 28 – Matt Clement becomes the 21st big league pitcher and the first Chicago Cubs pitcher in over a century to hit three batters in one inning, to tie a major league record. The victims plunked in the fifth inning of the first game of a doubleheader against Pittsburgh are Bobby Hill, Jason Kendall and Craig Wilson.
- June 12 – San Francisco Giants outfielder Barry Bonds drills a solo home run (the 675th of his career) off the Baltimore Orioles' Rodrigo López, who becomes the 400th pitcher to be a victim. Bonds' performance upstages a milestone afternoon by Rafael Palmeiro, who hits his 536th and 537th homers to move past Mickey Mantle into 11th place on the career list. It is only the third time in baseball history that two players with 500 homers connect in the same game. Willie Mays and Ernie Banks did it in 1970, and Mays and Hank Aaron both homered on May 8, 1971.
- June 20 – On Father's Day afternoon at Busch Stadium, with his father, Ken Griffey, Sr., in attendance, Cincinnati Reds outfielder Ken Griffey, Jr. goes deep on a 2-2 fastball from the St. Louis Cardinals' Matt Morris, securing a spot in the record books as the 20th player with 500 career home runs. The home run also ties Griffey Jr. with his father in career hits (2,143).
- June 24 – Carlos Beltrán is traded from the Royals to the Astros.
- June 25 – Larry Walker hits 3 home runs helping the Colorado Rockies beat the Cleveland Indians 10-8.
- June 26 – With a 6-4 victory over the Florida Marlins, the Tampa Bay Devil Rays have a record of 36-35, becoming the first team in Major League history to have a winning record after being 18 games under .500. At one point in the season, they are 10-28, then go on a 26-7 run. Before falling under .500 for good in July, the Rays win or tie 13 out of 14 series, including three straight sweeps during a club-record 12-game winning streak.
- June 27 – College World Series: Cal State Fullerton wins the NCAA College World Series, defeating Texas 3-2 to win the best-of-three championship series 2-0. The Longhorns later stir up controversy by refusing to accept the runner-up trophy.
- June 28 – David Bell hits for the cycle as the Philadelphia Phillies slug their way to a 14-6 victory over the Montreal Expos. Bell goes 4-for-4, scores two runs, and gets a career-high six RBI. He becomes the third player to hit for the cycle this season, joining the Pirates' Daryle Ward and the Brewers' Chad Moeller. Coincidentally, Ward and his father Gary Ward accomplish the feat, and when Bell achieves the honor, he joins his grandfather Gus Bell, who turned the trick on June 4, 1951.
- June 29 – At home, the Yankees' Tony Clark hits a deep-center two-run homer off Derek Lowe, to help his team to an 11-3 win over the Boston Red Sox. Clark joins Bernie Williams and Danny Tartabull as the only players to reach the center-field bleachers more than once since the remodeled Yankee Stadium opened in 1976.
- July 1 – The Yankees defeat the Red Sox 5-4 in 13 innings in a game notable for Derek Jeter making a running catch and promptly flying into the stands to save a Red Sox run and John Flaherty's pinch-hit walk-off single that seals a three-game sweep for the Yankees.
- July 5 – Éric Gagné's consecutive saves streak ends at 84 in a 6-5 Los Angeles Dodgers victory against the Arizona Diamondbacks, the last team to keep him from converting a save. Gagné hasn't blown a save chance since David Dellucci hit a game-tying double on August 26, 2002. These are his only blown saves in 75 attempts at Dodger Stadium. During the streak, Gagné blew the lead in the 2003 Major League Baseball All-Star Game when he allowed a home run to the Texas Rangers' Hank Blalock, but that exhibition game did not count in the statistics.
- July 6 – Detroit Tigers pitcher Jason Johnson becomes the first player in Major League Baseball history to get permission to wear an insulin pump on the field. A diabetic, Johnson wears the pump on his belt on the left side of his lower back, in order to minimize the chance of it being hit by a bat or thrown ball.
- July 10 – Barry Bonds breaks his own record for intentional walks received in a season; amazingly, he breaks the former full-season record of 68, set in 2002, before the All-Star break. After three intentional walks in a 3-1 San Francisco Giants win over the Arizona Diamondbacks, his total stands at 71; he finishes with 120.
- July 13 – In the 75th All-Star Game, played at Minute Maid Park, the American League rocks Roger Clemens for six runs in the first inning, including home runs by Manny Ramírez and Alfonso Soriano, and coasts to a 9-4 victory over the National League before 41,886 fans. Mark Mulder is the winning pitcher, Clemens gets the loss, and Soriano is selected the MVP.
- July 16 – Cleveland Indians catcher Víctor Martínez hits three home runs, singles twice, draws a walk, and drives in a career-high seven runs in a perfect 5-for-5 game, recording his first career multi-homer game, as the Indians belt eight homers and 21 hits in an 18-6 rout of the Seattle Mariners. Matt Lawton, Casey Blake, Ben Broussard, Travis Hafner and Jody Gerut add shots; Lawton, Martínez and Blake homer in consecutive at-bats in the third inning. It is the first time Cleveland hits three consecutive homers since Jim Thome, Albert Belle, and Julio Franco accomplish the feat on September 12, 1996. Broussard, Martínez, Hafner and Gerut all homer in the ninth inning as the Indians match their team record for home runs in one game, previously accomplished at Milwaukee on April 25, 1997. Cleveland also sets a new Safeco Field HR record, surpassing the six homers hit by the Kansas City Royals in 2003. The major league record for home runs in a game is 10, set by the Toronto Blue Jays in 1987.
- July 16 – With his solo home run in the eighth inning of the Philadelphia Phillies' 5-1 victory over the New York Mets, Bobby Abreu joins Willie Mays, Bobby Bonds and Barry Bonds by reaching the elite 20-homers/20-steal plateau for a sixth straight season. This quartet is the only group of players to have six straight 20-20 seasons in major league history. Abreu also becomes the only member of the quartet with no family connection to Barry, his late father Bobby, or his godfather Willie.
- July 23 – At Fenway Park, Kevin Millar becomes the third player to hit three home runs in a Boston Red Sox-New York Yankees game, joining Lou Gehrig (1927) and Mo Vaughn (1997). Despite Millar's effort, the Yankees edge the Sox 8-7.
- July 24 – In a Red Sox 11-10 win over the Yankees, also at Fenway Park, Alex Rodriguez and Jason Varitek begin a bench-clearing brawl after Rodriguez was hit by a Bronson Arroyo pitch. Gabe Kapler and Tanyon Sturtze break into the fight, giving Sturtze a bloody ear.
- July 29 – New York Mets outfielder Eric Valent becomes the eighth player in Mets history to hit for the cycle to lead his team to a 10-1 victory over the Montreal Expos at Olympic Stadium. Valent goes 4 for 4 with a walk, drives in three runs and scores three times in becoming the fourth player in the majors this season to hit a single, double, triple, and home run in a game – joining Milwaukee's Chad Moeller, Pittsburgh's Daryle Ward, and Philadelphia's David Bell.
- July 30 – The Pittsburgh Pirates obtain OF/IF José Bautista from the New York Mets. Bautista becomes the 10th major leaguer to play for four teams in a season. He begins the year with Baltimore and also plays with Tampa Bay and Kansas City, in addition to Pittsburgh. The last to do so was Dan Miceli (2003). Before him, the four-in-one players were Frank Huelsman (1904), Willis Hudlin (1940), Paul Lehner (1951), Ted Gray (1955), Wes Covington (1961), Mike Kilkenny (1972), Dave Kingman (1977) and Dave Martinez (2000). Bautista is technically on five teams, because he is acquired by New York from Kansas City but is sent to Pittsburgh the same day.
- July 31 – The Boston Red Sox send five-time All-Star shortstop Nomar Garciaparra to the Chicago Cubs in a four-team deal that highlights clubs beating baseball's trade deadline. Montreal Expos shortstop Orlando Cabrera, Cubs shortstop Alex S. Gonzalez and Minnesota Twins first baseman Doug Mientkiewicz also move in the four-way trade. The Red Sox wind up with Cabrera and Mientkiewicz, both Gold Glovers; the Cubs get Garciaparra and minor league outfielder Matt Murton; Montreal acquires Gonzalez, pitcher Francis Beltrán and infielder Brendan Harris, and the Twins get minor league pitcher Justin Jones.
- August 3 – The St. Louis Cardinals' Albert Pujols, at age 24, becomes the first player ever to hit at least 30 home runs in each of his first four seasons. In 1936, Joe DiMaggio belted 29 home runs in his rookie season with the New York Yankees, and 30 or more in the following five seasons. Mark McGwire hit three homers in his 1986 first year with the Oakland Athletics, and 30 or more in the next four seasons. Pujols also becomes the first Cardinal in the franchise's 112-year history to hit 30 or more home runs in four consecutive years.
- August 6 – The Colorado Rockies send Larry Walker and a minor leaguer to the St. Louis Cardinals in exchange for Luis Martinez and Chris Narveson.
- August 7 – Greg Maddux of the Chicago Cubs defeats the San Francisco Giants 8-4, to earn his 300th career victory.
- August 8 – At Comerica Park, the Boston Red Sox outslug the Detroit Tigers 11-9, despite knuckleballer Tim Wakefield giving up a record-tying six home runs. Wakefield becomes the sixth pitcher since 1900 to yield six homers in a game, but the first since George Caster of the Philadelphia Athletics against the Red Sox on September 24, 1940. The others are Larry Benton (New York Giants, 1930), Sloppy Thurston (Brooklyn Dodgers, 1932), Bill Kerksieck (Philadelphia Phillies, 1939) and Al Thomas (St. Louis Browns, 1936). Both teams combine for 10 homers. For Boston, Kevin Youkilis homers twice and David Ortiz belts one. For Detroit, Iván Rodríguez and Eric Munson each connect twice, and one each to Carlos Peña, Dmitri Young and Craig Monroe. In 1886, Charlie Sweeney of the St. Louis Maroons in the National League gave up seven homers in a game, according to the Elias Sports Bureau.
- August 10 – At Great American Ball Park, Adam Dunn of the Cincinnati Reds hits the first home run ever to land in another state. Against José Lima of the Los Angeles Dodgers, Dunn hits a ball that exits the ballpark in center field and bounces onto Mehring Way, which runs between GABP and the Ohio River. The ball then bounces onto a piece of driftwood in the river, which is considered Kentucky territory. Despite Dunn's blast, which is measured at 535 feet (to date, the longest in the stadium's history), the Dodgers defeat the Reds 4-2.
- August 11 – Randy Wolf homers twice and throws seven solid innings to lead the Philadelphia Phillies to a 15-4 victory over Colorado. Wolf, who has four career homers, goes 3-for-3 and scored three runs.
- August 16 – Chipper Jones of the Atlanta Braves hits the 300th home run of his career in a 5-4 victory over the San Diego Padres.
- August 17 – Mark Teixeira becomes the second player in Texas Rangers history – and the first in more than 19 years – to hit for the cycle, leading Texas to a 16-4 rout of the visiting Cleveland Indians. He goes 4-for-5 and drives in a career-high seven runs for the club's first cycle since Oddibe McDowell accomplished the feat on July 23, 1985, against the Indians at Arlington Stadium. Teixeira is the fifth player to hit for the cycle this season.
- August 25 – The Cuban team defeats the Australia team, 6–2, in the final of the 2004 Summer Olympics Baseball tournament.
- August 26 – At Safeco Field, the Seattle Mariners' Ichiro Suzuki belts a leadoff home run in the ninth inning for his 200th hit in 2004, reaching the mark in fewer games than any player since 1930. In that season, Bill Terry of the New York Giants reached 200 in the Giants' 119th game, while Chuck Klein of the Philadelphia Phillies collected No. 200 in game No. 125. With the hit, which snaps an 0-for-11 slide, Ichiro becomes the first player in major league history to record at least 200 hits in each of his first four seasons. He hit 242 in 2001, 208 in 2002, and 212 in 2003.
- August 29 – Pabao of Willemstad, Curaçao wins the 2004 Little League World Series.
- August 31 – Omar Vizquel goes 6-for-7 to tie the AL record for most hits in a nine-inning game as the Cleveland Indians roll to a 22-0 rout of the New York Yankees, who endure the worst shutout loss in league history. The only other players with seven hits in a nine-inning game are Rennie Stennett (Pittsburgh in 1975) and Wilbert Robinson (Orioles in 1892). Cleveland matches the largest shutout in the majors since 1900, set by the Pittsburgh Pirates against the Chicago Cubs on September 16, 1975. Prior to this, the Yankees had never lost by more than 18 runs, falling 24-6 at Cleveland on July 29, 1928, and 19-1 at home against the Detroit Tigers on June 17, 1925. Previously, the Yankees' biggest shutout loss was 15-0 at home against the Chicago White Sox on May 4, 1950. Cleveland sets a team record for largest shutout win, topping its 19-0 rout of the Boston Red Sox on May 18, 1955.
- September 6 – Keith Ramsey of the Kinston Indians in the Carolina League tosses a perfect game against the Myrtle Beach Pelicans.
- September 9 – Joe Randa becomes the first player in AL history to have six hits and six runs in the same nine-inning game in the Kansas City Royals' 26-5 victory over the Detroit Tigers in the first game of a doubleheader.
- September 17 – The San Francisco Giants' Barry Bonds becomes just the third player in major league history to hit 700 career home runs. Bonds joins the select company of Hall of Famers Hank Aaron (755) and Babe Ruth (714) when he connects on an 0-1 slider from San Diego Padres hurler Jake Peavy in the third inning.
- September 17 – At Safeco Field, the Seattle Mariners defeat the Oakland Athletics 6-3. Rookie Greg Dobbs' three-run pinch-hit double starts Seattle's five-run seventh inning. Meanwhile, Edgar Martínez gets his 1,000th career RBI as a designated hitter – a record for RBI at the position – and Ichiro Suzuki breaks the major league record with his 199th single of the season in the seventh. He betters the mark of 198 set by Lloyd Waner of the Pittsburgh Pirates in 1927.
- September 18 – The St. Louis Cardinals become the first major league team to clinch a playoff spot this season, winning the NL Central Division for the third time in five seasons. A few hours after the Cardinals beat the Arizona Diamondbacks 7-0, the playoff berth is clinched when the San Francisco Giants lose to the San Diego Padres 5-1. When the Chicago Cubs lose 6-5 at the Cincinnati Reds, the division title is assured.
- September 18 to September 19 – The players from Nippon Professional Baseball launch the first strike in NPB history after an unsuccessful negotiation centering on the proposed merger of the Osaka Kintetsu Buffaloes and the Orix BlueWave, which is considered a steppingstone to merging the Pacific League and Central League. The strike lasts for two days, during which all professional and minor teams' games are suspended.
- September 20 – The Minnesota Twins clinch the AL Central Division with an 8-2 victory over the Chicago White Sox. The Twins do what no other Twins team does. They win three consecutive division titles and have four winning seasons in a row.

- September 23 – The NPB player dispute officially ends when the owners make an agreement with players to allow a new team to join the Pacific League and fill the void caused by the merger of the Buffaloes and Blue Wave in the 2005 season to form the Orix Buffaloes. The Tohoku Rakuten Golden Eagles later become the team to fill the place.

- September 30
- Bernie Williams hits a two-run homer in the ninth inning as the New York Yankees clinch their seventh straight AL East Division title, beating the Minnesota Twins 6-4 for their 100th victory of the season. The Yankees become just the fourth team in baseball history to post three straight 100-win seasons, joining the Atlanta Braves (1997-99), Baltimore Orioles (1969-71) and Philadelphia Athletics (1929-31).
- David Ortiz and Manny Ramírez of the Boston Red Sox become the first pair of American League teammates since New York Yankees' Babe Ruth and Lou Gehrig in 1931 to both bat .300 with 40 home runs and 100 runs batted in. The feat is accomplished only 11 other times.
- October 1 – Ichiro Suzuki surpasses George Sisler's 84-year-old record of 257 hits in a single season. After this game, Ichiro collects 259 hits in the season with two games left; he finishes the season with 262 hits.

The Angels also earn their first playoff berth since 2002, when they win the World Series as the wild card. The Angels, who trail Oakland by one game four days before, are tied for first place when the three-game series starts, and many expect the race to come down to the last day of the season; but Anaheim ends the suspense with two consecutive victories.
- October 2 – Steve Finley's walk-off grand slam caps a seven-run rally in the bottom of the ninth inning, and the Los Angeles Dodgers win the NL West Division title by beating the San Francisco Giants 7-3.

- October 3
- The Houston Astros clinch a berth in the playoffs with their 18th consecutive home victory by beating the Colorado Rockies 5-3 to win the NL wild card. Houston wins the final seven games of the regular season and nine of the last 10 to complete an amazing late-season push for the playoffs under manager Phil Garner, who replaces Jimy Williams at the All-Star break. The Astros are a season-worst 56-60 on August 14. Since then, the team compiles a major league-best 36-10.
- The Montreal Expos conclude their 36-year history by losing to the New York Mets 8-1 at Shea Stadium, the franchise's final game before its move to Washington, D.C.
