# Fielding Independent Pitching (FIP)

### Definition

FIP is similar to ERA, but it focuses solely on the events a pitcher has the most control over -- strikeouts, unintentional walks, hit-by-pitches and home runs. It entirely removes results on balls hit into the field of play.

For example: If a pitcher has surrendered a high average on balls in play, his FIP will likely be lower than his ERA. Balls in play are not part of the FIP equation because a pitcher is believed to have limited control over their outcome.

### The formula

Where the "FIP constant" puts FIP onto the same scale as the entire league's ERA: ((HR x 13) + (3 x (BB + HBP)) - (2 x K)) / IP + FIP constant.
