Players Roger Connor is believed to have been the first major league player to hit a grand slam, on
September 10, 1881, for the
Troy Trojans of the National League (NL) at
Riverside Park in
Greenbush, New York (now
Rensselaer). Although
Charlie Gould hit one for the
Boston Red Stockings of the
National Association (NA) in 1871, the NA is not recognized by
Major League Baseball (MLB) as a major league.
Alex Rodriguez has 25 career grand slams, the most by any player in MLB history. In
1968,
Jim Northrup of the
Detroit Tigers set a major league record by hitting three grand slams in a week, including two in consecutive at-bats of a game. This feat (three grand slams in one week) would later be matched by
Larry Parrish of the
Texas Rangers in 1982. However, Northrup hit his three slams in only 14 plate appearances, setting a record that still stands Several grand slams, the first being Connor's in 1881, consisted of a player hitting a
walk-off grand slam for a one-run victory; some baseball observers call this an "ultimate grand slam".
Roberto Clemente is the only player to have hit a walk-off
inside-the-park grand slam in a one-run victory; when the
Pittsburgh Pirates defeated the
Chicago Cubs 9–8 on
July 25, 1956 at
Forbes Field, a park known for its spacious outfield. Four players hit a grand slam in their first Major League at-bat:
Bill Duggleby (1898),
Jeremy Hermida (2005),
Kevin Kouzmanoff (2006), and
Daniel Nava (2010). Kouzmanoff, Nava, and Duggleby hit theirs on the first pitch; Hermida's grand slam was in a
pinch-hit at bat.
Tony Cloninger is the only pitcher to hit two grand slams in one game, for the
Atlanta Braves in a 1966 contest against the
San Francisco Giants.
Félix Hernández of the
Seattle Mariners became the first American League pitcher since the
designated hitter rule went into effect in 1973 to hit a grand slam when he did so on June 23, 2008, against the
New York Mets in an interleague game. The only major league player to hit two grand slams in one inning is
Fernando Tatís of the
St. Louis Cardinals, in 1999, both grand slams coming off
Los Angeles Dodgers' pitcher
Chan Ho Park in the third inning. Tatis was only the second National League player to hit two grand slams in one game, joining Cloninger. Park was only the second pitcher in major league history to give up two grand slams in one inning, joining
Bill Phillips of the
Pittsburgh Pirates, who did it in 1890, one to
Tom Burns and one to
Malachi Kittridge. Therefore, Park was the first to give up both to the same batter. Tatis had never hit a grand slam before in his career.
Bill Mueller is the only player to hit grand slams from both sides of the plate in the same game, when he hit two in 2003 for the
Boston Red Sox against the
Texas Rangers.
Robin Ventura is the only player to hit a grand slam in both games of a doubleheader, when he did so in 1999 for the
New York Mets against the
Milwaukee Brewers. In
Japan's professional league, the feat of multiple grand slams in a single inning by a team has been accomplished three times; most recently on
April 1, 2007 by
José Fernández and
Takeshi Yamasaki of the
Tohoku Rakuten Golden Eagles. The
Fukuoka Daiei Hawks accomplished the feat in 1999.
Team In 2006, the
Chicago White Sox hit grand slams in three consecutive games against the
Houston Astros (June 23–25). Scott Podsednik hit the only grand slam of his career in the series opener. Joe Crede followed up with a slam of his own on in the second game, and Tadahito Iguchi hit a game tying grand slam in the bottom of the ninth with two outs in the series finale. The White Sox became the first team to accomplish this since the
Detroit Tigers in 1993. On the other hand, the 2007
Kansas City Royals surrendered grand slams in three straight games; two against the
Baltimore Orioles (April 13–14) and one against the Tigers (April 16). On August 25, 2011, the
New York Yankees became the first team in MLB history to hit three grand slams in one game.
Robinson Canó,
Russell Martin and
Curtis Granderson took
Oakland Athletics pitchers
Rich Harden,
Fautino de los Santos, and
Bruce Billings deep, with each grand slam being hit in a different inning. The Yankees would win the game 22–9. On June 3, 2017, a record-breaking seven grand slams were hit on one day: One each for the
Los Angeles Dodgers,
Milwaukee Brewers,
Atlanta Braves,
Colorado Rockies,
Chicago Cubs,
Seattle Mariners, and the
Los Angeles Angels of Anaheim whose
Albert Pujols hit his 600th career home run. On August 20, 2020, the
San Diego Padres became the first team to hit a grand slam in four consecutive games when
Fernando Tatis Jr,
Wil Myers,
Manny Machado, and
Eric Hosmer each hit a grand slam in a series against the
Texas Rangers. On October 16, 2021, in Game 2 of the
2021 ALCS against the
Houston Astros, the
Boston Red Sox became the first team to hit two grand slams in one postseason game when
J. D. Martinez hit one in the first inning and
Rafael Devers hit one in the second. Two days later, in Game 3 of the series,
Kyle Schwarber hit another slam for Boston to make the Red Sox the first team to hit three grand slams in one postseason series. ==Notable calls==
