Michael Rucker is a relief pitcher for the Seattle Mariners. In 2026 he struck out 28 batters over 24.0 innings across 23 appearances, going 0-3. His ERA of 3.75 was 10.2% lower than the league average of 4.18 — 10th of 15 on his team, and 213th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.50 FIP suggests the ERA was no fluke. He missed bats on 27.2% of swings (13.1% of every pitch he threw), walked 7.8% of the batters he faced and struck out 27.5%. His 0.3 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.
