Matt Bush was a relief pitcher for the Milwaukee Brewers. In 2023 he struck out 10 batters over 10.1 innings across 12 appearances, going 0-2. His ERA of 9.58 was 121.2% higher than the league average of 4.33. Stripping out defence, his 9.35 FIP suggests the ERA was no fluke. He missed bats on 30.2% of swings (13.4% of every pitch he threw), walked 12.5% of the batters he faced and struck out 20.8%. His -0.5 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.
