Mac Sceroler is a relief pitcher for the Baltimore Orioles. In 2021 he struck out 11 batters over 7.2 innings across 5 appearances, going 0-0. His ERA of 14.09 was 230.2% higher than the league average of 4.27. Stripping out defence, his 13.60 FIP suggests he pitched better than his ERA shows. He missed bats on 31.9% of swings (14.6% of every pitch he threw), walked 14.6% of the batters he faced and struck out 22.9%. His -0.8 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.
