Baseball Wiki

In the sport of baseball, a Grand Slam is a home run hit with all the bases occupied, thereby scoring 4 runs - the most possible on a single play. Lou Gehrig hit 23 career grand slams, the most by any player in Major League Baseball. Don Mattingly set the single-season record with 6 grand slams in 1987 - remarkably, the only 6 of his entire career. 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.

On several occasions in major league history, the first being Connor's 1881 home run, a player has hit a walk-off grand slam for a 1-run victory; some baseball observers call this an "ultimate grand slam" [1] [2].

In the 2005 major league season, grand slams accounted for 132 of the 5017 total home runs hit (2.6 %). On June 13 and 14, 2006, the Minnesota Twins recorded the rare feat of two grand slams in consecutive games against the Boston Red Sox, including a walk off grand slam by Jason Kubel in the 12th inning on the 13th. Also in 2006, the Chicago White Sox hit grand slams in three consecutive games against the Houston Astros on June 23, June 24, and June 25. Two of the three grand slams were hit by second baseman Tadahito Iguchi. They became the first team to accomplish this feat since the Detroit Tigers did it in 1993.

In the 2006 major league season, Travis Hafner of the Cleveland Indians set a major league record by hitting five grand slams prior to the All-Star Break. Weeks later on July 16, Carlos Beltran and Cliff Floyd of the New York Mets hit grand slams during an 11-run 6th inning in a game against the Chicago Cubs, the 7th time two grand slams have been hit in a single inning (the 4th time in National League history).
