Robert Gasser is a starting pitcher for the Milwaukee Brewers. In 2026 he struck out 61 batters over 67.0 innings across 13 appearances, 13 of them starts, going 3-4. His ERA of 4.57 was 9.4% higher than the league average of 4.18 — 13th of 16 on his team, and 313th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.52 FIP suggests the ERA was no fluke. He missed bats on 22.0% of swings (11.1% of every pitch he threw), walked 6.3% of the batters he faced and struck out 21.3%. His 0.4 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.
