Sean White was a relief pitcher for the Seattle Mariners. In 2010 he struck out 15 batters over 34.1 innings across 38 appearances, going 0-1. His ERA of 5.24 was 28.5% higher than the league average of 4.08 — 12th of 15 on his team, and 378th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.68 FIP suggests he pitched better than his ERA shows. He missed bats on 17.3% of swings (8.3% of every pitch he threw), walked 7.3% of the batters he faced and struck out 10.0%. His -0.1 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.

Sean White'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.
