Adam Pettyjohn was a relief pitcher for the Cincinnati Reds. In 2008 he struck out 1 batter over 4.0 innings across 3 appearances, going 0-1. His ERA of 20.25 was 368.3% higher than the league average of 4.32. Stripping out defence, his 11.38 FIP suggests he pitched better than his ERA shows. He missed bats on 16.7% of swings (6.5% of every pitch he threw), walked 7.7% of the batters he faced and struck out 3.8%. His -0.3 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.
