Jonathan Bermúdez is a relief pitcher for the Miami Marlins. In 2024 he struck out 4 batters over 6.2 innings across 3 appearances, going 0-1. His ERA of 8.10 was 98.6% higher than the league average of 4.08. Stripping out defence, his 7.67 FIP suggests he pitched better than his ERA shows. He missed bats on 17.3% of swings (7.4% of every pitch he threw), walked 6.1% of the batters he faced and struck out 12.1%. 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.
