Jerome Williams was a relief pitcher for the St. Louis Cardinals. In 2016 he struck out 8 batters over 17.1 innings across 11 appearances, going 0-0. His ERA of 5.71 was 36.3% higher than the league average of 4.19. Stripping out defence, his 6.61 FIP suggests that his ERA had some help behind him. He missed bats on 21.4% of swings (10.3% of every pitch he threw), walked 7.4% of the batters he faced and struck out 9.9%. His -0.4 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.
