Jake Walsh was a relief pitcher for the St. Louis Cardinals. In 2022 he struck out 5 batters over 2.2 innings across 3 appearances, going 0-1. His ERA of 13.50 was 240.2% higher than the league average of 3.97. Stripping out defence, his 2.74 FIP suggests he pitched better than his ERA shows. He missed bats on 21.4% of swings (9.2% of every pitch he threw), walked 13.3% of the batters he faced and struck out 33.3%. 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.

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.
