Grant Holman is a relief pitcher for the Athletics. In 2025 he struck out 17 batters over 23.0 innings across 22 appearances, going 4-2. His ERA of 5.09 was 22.3% higher than the league average of 4.16 — 15th of 19 on his team, and 419th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 4.66 FIP suggests he pitched better than his ERA shows. He missed bats on 27.7% of swings (13.0% of every pitch he threw), walked 8.7% of the batters he faced and struck out 16.5%. His -0.0 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.
