Brett Martin is a relief pitcher for the Texas Rangers. In 2022 he struck out 40 batters over 50.0 innings across 55 appearances, going 1-7. His ERA of 4.14 was 4.3% higher than the league average of 3.97 — 11th of 21 on his team, and 317th of 546 among MLB pitchers with 20+ innings. Stripping out defence, his 3.63 FIP suggests he pitched better than his ERA shows. He missed bats on 24.8% of swings (12.5% of every pitch he threw), walked 8.5% of the batters he faced and struck out 18.9%. 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.
