Gavin Hollowell is a relief pitcher for the Chicago Cubs. In 2026 he struck out 13 batters over 14.1 innings across 14 appearances, going 0-0. His ERA of 2.51 was 39.9% lower than the league average of 4.18. Stripping out defence, his 4.97 FIP suggests that his ERA had some help behind him. He missed bats on 27.8% of swings (11.9% of every pitch he threw), walked 12.9% of the batters he faced and struck out 21.0%. His -0.1 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.
