Batting Average on Balls In Play (BABIP) measures how often a ball in play goes for a hit. A ball is “in play” when the plate appearance ends in something other than a strikeout, walk, hit batter, catcher’s interference, sacrifice bunt, or home run.
Formula for BABIP:
(Hits -Homers)/(At-Bats-Strikeouts-Homers+Sac Flies)
What Does BABIP Do?
Luck plays no part in this stat. Speedy players that can leg out hits will have higher BABIP’s. Line drive hitters will have more balls drop in hit for hitter and have a higher BABIP. Spacious ball parks (Coors Field)will give a better stat line in this area than smaller cozier (Petco Park)ball parks.
An average BABIP is around .300. It does change from year to year.
