Conner Greene is a relief pitcher for the Baltimore Orioles. In 2021 he struck out 26 batters over 25.1 innings across 24 appearances, going 1-3. His ERA of 7.11 was 66.6% higher than the league average of 4.27 — 19th of 23 on his team, and 540th of 567 among MLB pitchers with 20+ innings. Stripping out defence, his 3.41 FIP suggests he pitched better than his ERA shows. He missed bats on 29.8% of swings (15.0% of every pitch he threw), walked 9.9% of the batters he faced and struck out 21.5%. His 0.4 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.
