Tom Cosgrove is a relief pitcher for the Washington Nationals. In 2026 he struck out 7 batters over 10.0 innings across 10 appearances, going 0-1. His ERA of 2.70 was 35.3% lower than the league average of 4.18. Stripping out defence, his 4.19 FIP suggests that his ERA had some help behind him. He missed bats on 13.4% of swings (6.3% of every pitch he threw), walked 7.5% of the batters he faced and struck out 17.5%. 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.

Head to head
Put Tom Cosgrove beside up to three others.
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.
