Grant Holmes is a starting pitcher for the Atlanta Braves. In 2026 he struck out 94 batters over 114.0 innings across 23 appearances, 22 of them starts, going 7-4. His ERA of 3.47 was 16.8% lower than the league average of 4.18 — 8th of 13 on his team, and 164th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.83 FIP suggests that his ERA had some help behind him. He missed bats on 26.8% of swings (13.0% of every pitch he threw), walked 9.9% of the batters he faced and struck out 19.3%. 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.
