Devin Williams is a relief pitcher for the New York Mets. In 2026 he struck out 51 batters over 38.2 innings across 42 appearances, going 3-2. His ERA of 4.66 was 11.5% higher than the league average of 4.18 — 11th of 16 on his team, and 322nd of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.09 FIP suggests he pitched better than his ERA shows. He missed bats on 34.9% of swings (17.7% of every pitch he threw), walked 11.8% of the batters he faced and struck out 28.7%. His 0.7 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.
