Sean Newcomb is a relief pitcher for the Chicago White Sox. In 2026 he struck out 84 batters over 90.1 innings across 60 appearances, going 2-5. His ERA of 3.09 was 26.1% lower than the league average of 4.18 — the third best on his team, and 102nd of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.21 FIP suggests the ERA was no fluke. He missed bats on 23.9% of swings (10.9% of every pitch he threw), walked 9.1% of the batters he faced and struck out 22.6%. His 1.6 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.

Sean Newcomb's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
