Penn Murfee was 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.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.

Penn Murfee's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
