==Events==

===January===
* 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 [[starting pitcher|starter]] and a [[closer (baseball)|closer]], becoming the only pitcher in Major League history to collect 100 [[complete game]]s and 100 [[save (baseball)|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.<ref>[https://baseballhall.org/hall-of-famers/eckersley-dennis Dennis Eckersley biography]. ''Baseball Hall of Fame official website''. Retrieved on February 26. 2018.</ref> 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.<ref>[https://baseballhall.org/hall-of-famers/molitor-paul Paul Molitor biography]. ''Baseball Hall of Fame official website''. Retrieved on February 26. 2018.</ref>
* January 12 – [[Roger Clemens]] signs a contract with the [[Houston Astros]], ending his retirement after the 2003 season.

===February===
* February 15 – [[Alex Rodriguez]] is traded by the [[Texas Rangers (baseball)|Texas Rangers]] to the [[New York Yankees]] in exchange for [[Alfonso Soriano]] and a player to be named later.

===March===
* 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 in baseball|1947 season]]. Previously, Robinson's uniform number "42" was retired for all time in a ceremony at [[Shea Stadium]] in [[1997 in baseball|April 1997]] to mark the 50th anniversary of his achievement. His debut with the [[History of the Brooklyn Dodgers|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 Major League Baseball All-Star Game|1976]] and [[1996 Major League Baseball All-Star Game|1996]] [[Major League Baseball All-Star Game]]s were held at the venue, and the Vet also hosted the annual [[Army–Navy Game|Army-Navy football game]] seventeen times between 1980 and 2001.

===April===
* 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 12 – [[Barry Bonds]] ties his godfather [[Willie Mays]] for third on the all-time career home run list with his 660th home run coming in the fifth inning off of [[Milwaukee Brewers]] starter [[Matt Kinney]].

* April 13 – Pitcher [[Dennis Eckersley]], catcher-manager [[Bill Carrigan]] and infielders [[Wade Boggs]], [[Billy Goodman]] and [[Pete Runnels]] are selected for induction into the [[Boston Red Sox Hall of Fame]].

* April 14 – At [[Yankee Stadium (1923)|Yankee Stadium]], [[Kevin Brown (right-handed pitcher)|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 Cubs|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 (baseball)|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 [[Hitting for the cycle|hit for the cycle]], the first to do it at home, and the first since [[Paul Molitor]] did it on May 15, {{Baseball year|1991}} against the [[Minnesota Twins]].

===May===
* 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, {{Baseball year|1983}}, at [[Tiger Stadium (Detroit)|Tiger Stadium]].
* May 12 – In one of the most remarkable [[at-bat]]s in major league history, [[Alex Cora]] [[foul ball|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 (baseball)|perfect game]], throwing 13 strikeouts on his way to a 2-0 defeat of the [[Atlanta Braves]].
* May 26 – The [[Pittsburgh Pirates]]' [[Daryle Ward]] [[Hitting for the cycle|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 (outfielder)|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, {{Baseball year|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 (baseball)|Bobby Hill]], [[Jason Kendall]] and [[Craig Wilson (first baseman)|Craig Wilson]].

===June===
* June 12 – [[San Francisco Giants]] outfielder [[Barry Bonds]] drills a solo home run (the 675th of his career) off the [[Baltimore Orioles]]' [[Rodrigo López (baseball)|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 {{Baseball year|1970}}, and Mays and [[Hank Aaron]] both homered on May 8, {{Baseball year|1971}}.
* June 20 – On [[Father's Day]] afternoon at [[Busch Stadium II|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 (baseball)|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 consecutive sweeps during a club-record 12-game winning streak.
* June 27 – [[2004 College World Series|College World Series]]: [[California State University, Fullerton|Cal State Fullerton]] wins the NCAA [[College World Series]], defeating [[University of Texas at Austin|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 (baseball)|David Bell]] [[Hitting for the cycle|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 (outfielder)|Gary Ward]] accomplish the feat, and when Bell achieves the honor, he joins his grandfather [[Gus Bell]], who turned the trick on June 4, {{Baseball year|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 (1923)|Yankee Stadium]] opened in {{Baseball year|1976}}.

===July===
* 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 (baseball)|Texas Rangers]]' [[Hank Blalock]], but that exhibition game did not count in the statistics.
* July 6 – [[Detroit Tigers]] pitcher [[Jason Johnson (baseball)|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.<ref>[https://www.nytimes.com/2004/07/06/sports/baseball-belt-pump-helps-pitcher-with-diabetes.html NYTimes.com – BASEBALL; Belt Pump Helps Pitcher With Diabetes]</ref>
* 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 [[2004 Major League Baseball All-Star Game|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 (baseball)|National League]] before 41,886 fans.

* 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.

Teixeira is the fifth player to hit for the cycle this season.

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 {{Baseball year|2001}}, 208 in {{Baseball year|2002}}, and 212 in {{Baseball year|2003}}.
