Seranthony Domínguez is a relief pitcher for the Chicago White Sox. In 2026 he struck out 64 batters over 61.0 innings across 66 appearances, going 5-3. His ERA of 3.69 is 11.7% lower than the league average of 4.18 — 8th of 18 on his team, and 204th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 4.59 FIP suggests that his ERA had some help behind him. He missed bats on 28.0% of swings (13.1% of every pitch he threw), walked 12.1% of the batters he faced and struck out 24.9%. 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.

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.
