Bill Simmons Fun Sabermetric Statistics #6

The sixth sabermetric stat he mentions is BABIP (Batting Average on Balls In Play)

Formula: (hits-homeruns) / (at-bats – K’s – HR + sac-flies).

Goal: Measure BABIP to determine whether a pitcher or hitter had good luck or bad luck. In 2009, the major league BABIP average was .299. If a pitcher’s BABIP dipped well below that number, he might have had good luck. If it rose well above that number, he likely had terrible luck. The reverse goes for hitters.

Flaw: Too many variables can determine a hitter’s BABIP. Good for pitchers.
