Penn Murfee is a relief pitcher for the Chicago White Sox. In 2025 he struck out 13 batters over 12.2 innings across 15 appearances, going 0-1. His ERA of 7.82 was 87.9% higher than the league average of 4.16. Stripping out defence, his 5.58 FIP suggests he pitched better than his ERA shows. He missed bats on 25.7% of swings (11.6% of every pitch he threw), walked 7.9% of the batters he faced and struck out 20.6%. His -0.1 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.

Head to head
Put Penn Murfee beside up to three others.
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.
