Joe Kelly is a relief pitcher for the Los Angeles Dodgers. In 2024 he struck out 35 batters over 32.0 innings across 35 appearances, going 1-1. His ERA of 4.78 was 17.2% higher than the league average of 4.08 — 16th of 21 on his team, and 393rd of 541 among MLB pitchers with 20+ innings. Stripping out defence, his 4.57 FIP suggests the ERA was no fluke. He missed bats on 22.0% of swings (10.1% of every pitch he threw), walked 11.2% of the batters he faced and struck out 24.5%. 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.

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.
