A statistic in baseball that records the amount of times a batter has grounded into a double play for every at-bat he has taken. This is measured by dividing the player's total number of at-bats by the number of ground balls he has hit resulting in the defensive team turning a double play.
Strategically, a team can use this statistic when deciding how to go about pitching to a batter at the plate with a man on first base. Typically, the league leaders in this statistic will be faster runners, as they can "beat out" the throw to first base and avoid a double play, even when they do hit ground balls. Players who tend to hit a lot of line drives or fly balls rather than grounders will also have a high AB/GIDP stat.
