Tommy Doyle is a relief pitcher for the Colorado Rockies. In 2023 he struck out 18 batters over 23.2 innings across 15 appearances, going 0-1. His ERA of 6.85 was 58.0% higher than the league average of 4.33 — 17th of 21 on his team, and 521st of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 6.13 FIP suggests he pitched better than his ERA shows. He missed bats on 29.7% of swings (14.8% of every pitch he threw), walked 12.6% of the batters he faced and struck out 17.5%. 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.
