Definition of BABIP
: batting average on balls in play ◆BABIP is a measure of how often a base hit results when a batter puts a ball in play in fair territory other than by hitting a home run. For a pitcher it is the cumulative average on balls in play achieved by all the batters the pitcher faces. If you're looking for a pitcher to turn around your favorite team, consider three stats: Batting average allowed on balls in play (BABIP), strikeout-to-walk ratio and homers allowed. An average BABIP is around .300, and pitchers who are far above or below this number typically converge on it as the year progresses. — Joe Sheehan, Sports Illustrated, 19 May 2008 Part of the reason his BABIP has been so low is because he's allowed fewer line drives this year than he did a year ago … — Brian MacPherson, Providence Journal-Bulletin, 4 June 2010 Every at-bat—disregarding walks—can, really, result in one of three different outcomes: a strikeout, a home run or a ball hit into the field. Of the thousands and thousands of baseballs hit into play each season, almost exactly 30 percent of them land for hits, essentially without fail, on a large enough scale. That is a .300 BABIP. Entering play Saturday, the Angels have had almost 33 percent of their balls hit into the field land for hits for a .328 BABIP, the third-highest mark in the majors. — Pedro Moura, Orange County Register (California), 28 Apr. 2013
