José Fermin is a relief pitcher for the Los Angeles Angels. In 2026 he struck out 45 batters over 38.1 innings across 35 appearances, going 3-2. His ERA of 3.29 was 21.3% lower than the league average of 4.18 — 5th of 18 on his team, and 128th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.23 FIP suggests that his ERA had some help behind him. He missed bats on 31.8% of swings (15.5% of every pitch he threw), walked 11.4% of the batters he faced and struck out 27.1%. 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.
