Definition – What is Fielding Independent Pitching?

FIP evaluates a pitcher’s performance independent of the fielding team (except for the catcher).

It is part of a group of Defense-Independent Pitching Statistics (DIPS).

Fielding Independent Pitching (FIP) is critiqued for not evaluating pitchers on what truly matters in the game (runs allowed). Proponents of the system prefer it for its ability to give a more objective evaluation of a pitcher.

Formula – How to calculate FIP

FIP = ((13 x Home Runs) + (3 x Walks) – (2 x Strikeouts)) ÷ (Innings Pitched + (Outs Pitched ÷ 3))

Example

If a pitcher has: 43 Walks | 207 Strikeouts | 35 Home Runs | 202 Innings Pitched | 1 Out (Partial Inning) Pitched, then:
FIP = ((13 x 35) + (3 x 43) – (2 x 207)) / (202 + (1 / 3))
FIP = (455 + 129 – 414) / 202.333
FIP = 170 / 202.333
FIP = 0.8402
Therefore, the pitcher’s FIP is 0.840
