Kyle Muller is a relief pitcher for the Oakland Athletics. In 2024 he struck out 36 batters over 49.1 innings across 21 appearances, going 0-1. His ERA of 4.01 was 1.6% lower than the league average of 4.08 — 11th of 23 on his team, and 285th of 541 among MLB pitchers with 20+ innings. Stripping out defence, his 3.96 FIP suggests the ERA was no fluke. He missed bats on 22.7% of swings (11.7% of every pitch he threw), walked 5.0% of the batters he faced and struck out 17.8%. 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.
