Justin Anderson is a relief pitcher for the Chicago White Sox. In 2024 he struck out 57 batters over 53.1 innings across 56 appearances, going 1-2. His ERA of 4.39 was 7.6% higher than the league average of 4.08 — 9th of 19 on his team, and 342nd of 541 among MLB pitchers with 20+ innings. Stripping out defence, his 4.22 FIP suggests the ERA was no fluke. He missed bats on 29.7% of swings (14.0% of every pitch he threw), walked 13.2% of the batters he faced and struck out 23.6%. 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.

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.
