Joel Zumaya was a relief pitcher for the Detroit Tigers. In 2010 he struck out 34 batters over 38.1 innings across 31 appearances, going 2-1. His ERA of 2.58 was 36.7% lower than the league average of 4.08 — the best on his team, and 52nd of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 2.50 FIP suggests the ERA was no fluke. He missed bats on 20.3% of swings (10.2% of every pitch he threw), walked 7.1% of the batters he faced and struck out 21.8%. His 0.9 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.

Joel Zumaya's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

How these are computed

wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
