Jason Anderson was a relief pitcher for the New York Yankees. In 2005 he struck out 2 batters over 5.2 innings across 3 appearances, going 1-0. His ERA of 7.94 was 85.1% higher than the league average of 4.29. Stripping out defence, his 6.02 FIP suggests he pitched better than his ERA shows. He missed bats on 13.5% of swings (5.2% of every pitch he threw), walked 25.9% of the batters he faced and struck out 7.4%. 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 2005 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.

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.
