It is calculated as: Hits Allowed divided by (Batters Faced minus Walks minus Hit Batsmen minus Sacrifice Hits minus Sacrifice Flies minus Catcher's Interference).

It is calculated as: B A A = H B F − B B − H B P − S H − S F − C I N T

BF is the number of batters faced by the pitcher

BB is the number of base on balls

HBP is the number of hit batsmen
