Jon Switzer was a relief pitcher for the New York Mets. In 2009 he struck out 3 batters over 3.1 innings across 4 appearances, going 0-0. His ERA of 8.10 was 87.4% higher than the league average of 4.32. Stripping out defence, his 7.90 FIP suggests the ERA was no fluke. He missed bats on 25.9% of swings (10.4% of every pitch he threw), walked 11.8% of the batters he faced and struck out 17.6%. 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.

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.
