Jake McGee is a relief pitcher for the San Francisco Giants. In 2022 he struck out 25 batters over 37.0 innings across 42 appearances, going 1-3. His ERA of 6.81 was 71.6% higher than the league average of 3.97 — the worst on his team, and 531st of 546 among MLB pitchers with 20+ innings. Stripping out defence, his 4.84 FIP suggests he pitched better than his ERA shows. He missed bats on 19.3% of swings (10.2% of every pitch he threw), walked 7.4% of the batters he faced and struck out 15.3%. His -0.2 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.
