Colin Selby is a relief pitcher for the Baltimore Orioles. In 2025 he struck out 14 batters over 14.0 innings across 11 appearances, going 0-2. His ERA of 3.21 was 22.7% lower than the league average of 4.16. Stripping out defence, his 3.42 FIP suggests the ERA was no fluke. He missed bats on 29.0% of swings (14.5% of every pitch he threw), walked 3.3% of the batters he faced and struck out 23.3%. His 0.2 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 Colin Selby 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.
