Brad Halsey was a relief pitcher for the Oakland Athletics. In 2006 he struck out 53 batters over 94.1 innings across 52 appearances, going 5-4. His ERA of 4.67 was 3.3% higher than the league average of 4.53 — 10th of 14 on his team, and 266th of 466 among MLB pitchers with 20+ innings. Stripping out defence, his 5.16 FIP suggests that his ERA had some help behind him. He missed bats on 15.9% of swings (7.2% of every pitch he threw), walked 10.7% of the batters he faced and struck out 12.3%. 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.

Not in the 2006 data: pitch types, recorded in every park from 2008. The play-by-play goes back to 2005, but the measurements on each pitch and batted ball arrived later, so the panels built from them are left off this season.

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.
