Dominic Leone is a relief pitcher for the Chicago White Sox. In 2024 he struck out 17 batters over 19.0 innings across 23 appearances, going 0-2. His ERA of 6.63 was 62.6% higher than the league average of 4.08. Stripping out defence, his 6.32 FIP suggests he pitched better than his ERA shows. He missed bats on 38.0% of swings (17.5% of every pitch he threw), walked 15.7% of the batters he faced and struck out 19.1%. His -0.4 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.
