Inputs

3.40

Fielding Independent Pitching. League average ≈ 3.90.

180
3.90

Role

Relievers get a leverage multiplier. Default 1.00 / 1.20.

(10.0 + 19.8) × 1.00 / 9.0 = 3.3 WAR

Methodology

This is a transparent, simplified fWAR pitching model. It starts from FIP versus league FIP, scales by innings, adds replacement value, applies a role leverage factor, and divides by runs per win.

RAA = ((lgFIP − FIP) / 9) × IP
Replacement = IP × (0.11 starter | 0.08 reliever)
pWAR = (RAA + Replacement) × leverage / RPW
RPW = 9 + (lgFIP − 3.90)

Limits No park factor, no infield-fly adjustment, no team defense, no exact FanGraphs G/F split. Use it to build intuition and check a claim — not to replace the published leaderboard.
