February

• February 17 – Baltimore Orioles pitcher Steve Bechler dies at the age of 23 of a heat stroke during spring training in Fort Lauderdale, Florida. A medical examiner found that Bechler's use of ephedra as a weight-loss supplement contributed to his death. Following this revelation, the Food and Drug Administration opened an inquiry, which resulted in the banning of ephedra products in the United States.

March

• March 31 – In the first-ever game at the Great American Ball Park the visiting Pittsburgh Pirates defeat the Cincinnati Reds 10-1. Ken Griffey Jr. collects the first hit in the stadium's history.

April

• April 3 – At 27 years, 249 days of age, Alex Rodriguez becomes the youngest player in major league history to hit 300 home runs. The Texas Rangers shortstop's fifth inning, three-run blast surpasses Hall of Famer Jimmie Foxx's mark, who accomplished the feat at 27 years, 328 days of age.
• April 4 – Sammy Sosa hits his 500th career home run, off Cincinnati Reds pitcher Scott Sullivan in the seventh inning at Great American Ball Park, becoming only the 18th player in major league history to hit 500 or more home runs, as well as the first Hispanic to do so.
• April 11 – The Montreal Expos defeat the New York Mets‚ 10–0‚ in their first of 22 home games they play in Puerto Rico this season.
• April 27 – Kevin Millwood of the Philadelphia Phillies pitches a no-hitter against the San Francisco Giants, striking out ten while walking three. Ricky Ledée's first-inning solo home run provides the game's only scoring.

May

• May 5 – Matt Stairs' home run off Houston Astros pitcher Wade Miller is estimated at 461 feet, making it the longest home run in the history of Minute Maid Park.
• May 10 – Jeff Torborg is fired as manager of the Florida Marlins after a 16-22 start. Jack McKeon is hired as his replacement.
• May 11 – Rafael Palmeiro hits his 500th career home run, off Cleveland Indians pitcher Dave Elder, becoming only the 19th player in major league history to reach the 500 mark.
• May 18 The Texas Rangers defeat the New York Yankees 5-1 to complete their first-ever three-game sweep of the Yankees at Yankee Stadium. John Thomson goes the distance for the victory, giving up only three hits and striking out nine.
• May 23 – Geremi González earns his first major league victory in nearly five years as the Tampa Bay Devil Rays beat the Anaheim Angels 3-1. González wins for the first time since June 28, 1998, while with the Chicago Cubs. He had elbow surgery in 1998 and 1999 before the Cubs released him in 2001.
• May 25 – The Toronto Blue Jays completed their first four-game sweep ever against the New York Yankees, winning 5–3 at Yankee Stadium and sending New York to its seventh consecutive home loss. The Yankees also dropped their season-high fourth in a row overall, a skid that thus dropped them out of the American League East lead, while their slump at Yankee Stadium was their worst since they lost 10 straight in the 1986 season. Now New York has lost 11 of the last 12 at home.^[1]
• May 26 – The Gary SouthShore RailCats play their inaugural home opener at the U.S. Steel Yard versus the Schaumburg Flyers.
• May 28 – Rafael Furcal, Mark DeRosa and Gary Sheffield hit home runs off Cincinnati Reds pitcher Jeff Austin in the bottom of the first inning, as the Atlanta Braves become only the second team in big league history to begin a game with three consecutive home runs. On April 13, 1987, the San Diego Padres' Marvell Wynne, Tony Gwynn and John Kruk did the same in the bottom of the first inning off San Francisco Giants starter Roger Mason.

June

• June 3 – Sammy Sosa is ejected from a game against the Tampa Bay Devil Rays for using a corked bat.
• June 11 – The Houston Astros set a major league record for combined pitchers in a no-hitter with six, against the New York Yankees. The pitchers are Roy Oswalt, Pete Munro, Kirk Saarloos, Brad Lidge, Octavio Dotel and Billy Wagner.

• June 23 – At AT&T Park, Barry Bonds of the San Francisco Giants becomes the first Major Leaguer with 500 career home runs and 500 career steals. After drawing a base on balls leading off the 11th inning, Bonds steals second, then eventually scores on Benito Santiago's single for the winning run in a 3-2 victory over the Los Angeles Dodgers.^[2]
• June 27 – The Boston Red Sox score a record-setting 10 runs in the first inning against the Florida Marlins before recording an out. Two Marlins pitchers, starter Carl Pavano and reliever Michael Tejera, pitch to a combined 11 batters and would not record an out. The Red Sox score 14 runs in the first inning, which ties the American League record. Johnny Damon ties the modern-day record for hits in an inning with three.

July

• July 15 – At U.S. Cellular Field, the American League wins the All-Star Game, beating the National League 7-6. Hank Blalock connects for a two-run, pinch-hit home run off Éric Gagné in the eighth inning to lead the rally. Garret Anderson is named the MVP, coming just one triple shy of hitting for the cycle in going 3-for-4 with a home run and two RBI. Brendan Donnelly is the winning pitcher, while Keith Foulke gets the save.
• July 27 – Gary Carter and Eddie Murray are inducted into the National Baseball Hall of Fame.
• July 29 – Against the Texas Rangers at The Ballpark in Arlington, Bill Mueller of the Boston Red Sox, in hitting three home runs, becomes the first player to hit a grand slam from each side of the plate in the same game. After hitting a solo home run off starter R. A. Dickey in the third, Mueller homers in the seventh with the bases loaded against left-hander Aaron Fultz. One inning later he hits his second grand slam, this time against right-hander Jay Powell. With the three home runs, Mueller drives in nine runs; the Red Sox defeat the Rangers 14-7.^[3]

August

• August 10 – Atlanta Braves shortstop Rafael Furcal becomes the twelfth player to turn an unassisted triple play in the fifth inning of a 3-2 loss to the St. Louis Cardinals.
• August 14 – The Northeast blackout of 2003 forces the cancellation of the game between the San Francisco Giants and New York Mets scheduled to be played that night at Shea Stadium. The game was ultimately not made up. Earlier that day, Giants left fielder Barry Bonds left the team to spend time with his ailing father Bobby Bonds and was placed on baseball's bereavement list which was created earlier that year.
• August 23 – Ron Guidry has his number 49 retired by the New York Yankees.
• August 30 – Barry Bonds of the San Francisco Giants homers against Randy Johnson of the Arizona Diamondbacks in his first game back since the death of his father Bobby Bonds one week prior. Bonds would later leave the game with an accelerated heart rate as the Giants would go on to win the game 2-1.

September

• September 5 – The Detroit Tigers' Mike Maroth becomes the first major league pitcher in 23 years to lose 20 games in a season when Detroit loses to the Toronto Blue Jays 8-6. Maroth (6-20) allows eight runs and nine hits in three-plus innings. The Oakland Athletics' Brian Kingman goes 8-20 in 1980.
• September 10 – The St. Louis Cardinals' Tony La Russa becomes the eighth manager in major league history to reach 2,000 wins as the Cardinals beat the Colorado Rockies 10–2. The 58-year-old La Russa posts a 2,000-1,782 record in 25 seasons with the Chicago White Sox, Oakland Athletics and St. Louis.
• September 14 – At Comerica Park, the Detroit Tigers set a franchise record for losses as they drop their 110th defeat, to the Kansas City Royals, 7-2.
• September 17 – In the Boston Red Sox' 7-0 loss to the Tampa Bay Devil Rays, Todd Walker's ninth-inning double is the Red Sox's 608th extra base hit of the season, breaking the major league record set by the 1996 Seattle Mariners.
• September 20 – Unlike this season, when the Montreal Expos play 25% of their home games in San Juan, Puerto Rico, the players vote to play their entire 2004 home schedule in Montreal. MLB owners, who collectively own the franchise, are still considering moving the Expos permanently to Washington, D.C., Portland, Oregon or Monterrey, Mexico, or continuing the present format by having the team split home games between different locations (Puerto Rico or Mexico and Montreal).
• September 21 – Second baseman Marcus Giles hits a home run off Brad Penny's 3-2 pitch, as the Atlanta Braves tie the NL record by having six players hit at least 20 home runs in a season. Along with Giles, Javy López, Gary Sheffield, Andruw Jones, Chipper Jones and Vinny Castilla equal the mark established by Eddie Mathews (32), Hank Aaron (32), Joe Torre (27), Felipe Alou (23), Mack Jones (31) and Gene Oliver (21) of the 1965 Milwaukee Braves.
• September 22:
  • The Detroit Tigers set an AL record with their 118th loss, falling 12-6 to the Kansas City Royals. The Philadelphia Athletics (36-117) had held the record. The Tigers finish the season with a 43-119 record. The 1962 Mets are the only team in history with a record worse than the 2003 Tigers.
  • Second baseman Alfonso Soriano breaks a major league season record by hitting his 13th leadoff home run of the year in the New York Yankees' 10-inning loss to the Chicago White Sox.
• September 25 – First baseman Carlos Delgado of the Toronto Blue Jays becomes the fifteenth player in Major League history to hit four home runs, including his 300th career home run, in one game helping Toronto beat the Tampa Bay Devil Rays, 10-8.
• September 28
  • The Atlanta Braves defeat the Philadelphia Phillies, 5-2, in the last game played at Philadelphia's Veterans Stadium.
  • The Colorado Rockies defeat the San Diego Padres, 10-8, in the final Padres game played at Qualcomm Stadium.

October

• October 14 – In Game 6 of the NLCS, with the Chicago Cubs just five outs away from eliminating the Florida Marlins, Cubs fan Steve Bartman deflects a foul fly ball away from Cubs left fielder Moisés Alou, allowing Florida's Luis Castillo to continue batting. The Cubs then proceed to fall apart, allowing eight runs in the inning to lose Game 6; they go on to lose Game 7, to continue the "Curse of the Billy Goat". The Marlins go on to win the World Series, and Bartman becomes a pariah in Chicago.
• October 16 – In Game 7 of the ALCS, Aaron Boone's walk-off home run off Tim Wakefield in the 11th inning ends a thrilling series between the New York Yankees and Boston Red Sox. Boston blows a three-run, eighth inning lead when Grady Little keeps ace Pedro Martínez in the game arguably too long instead of going to relief help from Alan Embree or Mike Timlin. The loss, which turns out to be the last manifestation of the "Curse of the Bambino", costs Little his job.
• October 22 – Roger Clemens of the New York Yankees starts Game 4 of the World Series and pitches seven strong innings before exiting the game to a standing ovation from both the crowd in attendance and the Florida Marlins (who left their dugout to join in), presumably because it was to be his final career start, having announced his retirement at the start of the season. The ovation would prove premature as Clemens came out of the retirement to sign with the Houston Astros before the 2004 season. The Marlins would eventually win the game, 4–3, on a 12th inning walk-off home run by Álex González to even the series at two games apiece.
• October 25 – In Game 6 of the World Series at Yankee Stadium, Josh Beckett, on three days' rest, pitches a 2–0, five-hit shutout over the favored New York Yankees, to give the Florida Marlins their second championship in 11 seasons. Beckett receives Series MVP honors.

November

• November 22 – 46–year old relief pitcher Jesse Orosco agrees to a minor league contract with the Arizona Diamondbacks and earns an $800,000 salary if he is added to the big league roster. He retires before the start of the 2004 season.
• November 26 – Hoping to add punch to their lineup, the Oakland Athletics trade catcher Ramón Hernández and disgruntled outfielder Terrence Long to the San Diego Padres in exchange for outfielder Mark Kotsay.
• November 28 – The Boston Red Sox send pitchers Casey Fossum, Brandon Lyon, Jorge de la Rosa, and a minor leaguer (Michel Goss) to the Arizona Diamondbacks in exchange for starter Curt Schilling.
