J.C. Mejía was a relief pitcher for the Milwaukee Brewers. In 2023 he struck out 13 batters over 11.1 innings across 9 appearances, going 1-0. His ERA of 5.56 was 28.3% higher than the league average of 4.33. Stripping out defence, his 4.31 FIP suggests he pitched better than his ERA shows. He missed bats on 26.8% of swings (12.1% of every pitch he threw), walked 6.0% of the batters he faced and struck out 26.0%. His 0.1 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.

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.
