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 does 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 is 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 accomplishes 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 plucked 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 do it in 1970, and Mays and Hank Aaron both homer 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 Colorado Rockies beat 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 turns 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 opens in 1976.
- 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 blows the lead in the 2003 Major League Baseball All-Star Game when he allows 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 is Dan Miceli (2003). Before him, the four-in-one players are 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 belts 29 home runs in his rookie season with the New York Yankees, and 30 or more in the following five seasons. Mark McGwire hits 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 sent 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 gives 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 homered twice and threw seven solid innings to lead the Philadelphia Phillies to a 15-4 victory over Colorado. Wolf, who has four career homers, went 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 accomplishes 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 reaches 200 in the Giants' 119th game, while Chuck Klein of the Philadelphia Phillies collects 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 hits 242 in 2001, 208 in 2002, and 212 in 2003.

The only 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. The Yankees never lose 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 is 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.
