A grand slam is a home run hit with all three bases occupied by baserunners ("bases loaded"), thereby scoring four runs—the most possible in one play. A walk-off home run with the bases loaded is therefore known as a walk-off grand slam. Since 1916 there have been more than 250 walk-off grand slams hit during Major League Baseball's regular season. From 1903 onwards, only one walk-off grand slam has been hit in the postseason, by Nelson Cruz of the Texas Rangers in Game 2 of the 2011 ALCS.
