Sean Gallagher was a relief pitcher for the Pittsburgh Pirates. In 2010 he struck out 43 batters over 57.2 innings across 46 appearances, going 2-1. His ERA of 5.77 was 41.6% higher than the league average of 4.08 — 14th of 17 on his team, and 414th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 5.45 FIP suggests he pitched better than his ERA shows. He missed bats on 21.4% of swings (8.3% of every pitch he threw), walked 15.0% of the batters he faced and struck out 15.8%. His -0.6 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.

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.
