Barry Bonds of the Giants has another outstanding year. He sets the all-time record for highest on-base percentage at .609, breaking his previous record of .582, set in 2002. He also posts a slugging average of .812, the fourth-highest ever, and also breaks his previous OPS record of 1.381, set in 2002, with a 2004 OPS of 1.422. Bonds also set a record for most walks in a season, with 232. Finally, with 120 intentional walks, he almost doubles his previous record of 68.
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.
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 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.

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.
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 does not blow a save chance since David Dellucci hits a 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 All-Star game when he allows a home run to the Texas Rangers' Hank Blalock, but that exhibition game will not be counted 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.

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.
August 3 - The St. Louis CardinalsAlbert 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 10 - At Great American Ballpark, 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 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.

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.
October 2 - The Anaheim Angels clinch their first AL West Division title in 18 years with a 5-4 victory over the Oakland Athletics. 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.
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.
October 9 - At Minnesota, the New York Yankees rally for four runs to tie the game in the eighth, then push across the winning run in the 11th on a wild pitch.

October 11 - The Houston Astros post a 12-3 triumph over the Atlanta Braves in the decisive fifth game of the NLDS. Winning a postseason series for the first time in the 43-year history of the franchise, the Astros earn a spot in the best-of-seven NLCS against the St. Louis Cardinals.
