FIP (Fielding Independent Pitching)

A pitching metric that isolates what a pitcher directly controls — strikeouts, walks, and home runs — eliminating fielding noise.

FIP (Fielding Independent Pitching) recalculates ERA using only the three outcomes a pitcher directly controls: strikeouts, walks (including hit-by-pitches), and home runs. Balls put in play — which depend heavily on fielding quality and luck — are removed entirely from the calculation.

A pitcher with a 3.80 ERA but a 3.20 FIP was likely unlucky: his fielders gave up extra hits on balls in play. A pitcher with a 3.20 ERA but a 3.80 FIP may have benefited from excellent defense. FIP predicts future ERA better than ERA itself.

FIP is scaled to match ERA, so the benchmarks are identical. Elite starters post FIPs below 3.00. xFIP normalizes home run rates as well, removing park effects on fly ball HR rates.

For Hall of Fame analysis, FIP is increasingly referenced by sabermetric-minded voters. AllFame's Career Value and Peak Performance dimensions incorporate FIP for pitchers alongside ERA+.
