Trevor Cahill was a starting pitcher for the Pittsburgh Pirates. In 2021 he struck out 32 batters over 37.0 innings across 9 appearances, 8 of them starts, going 1-5. His ERA of 6.57 was 54.0% higher than the league average of 4.27 — 22nd of 24 on his team, and 522nd of 567 among MLB pitchers with 20+ innings. Stripping out defence, his 4.06 FIP suggests he pitched better than his ERA shows. He missed bats on 22.9% of swings (10.1% of every pitch he threw), walked 8.4% of the batters he faced and struck out 19.3%. 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.
