 Batting average on balls in play

In baseball statistics, Batting average on balls in play (abbreviated BABIP) measures how many of a batter’s balls in play go for hits, or how many balls in play against a pitcher go for hits, excluding home runs.BABIP is commonly used as a red flag in sabermetric analysis, as a consistently high or low BABIP is hard to maintain—much more so for pitchers than hitters.
