Chicago White Sox
Penn Murfee has thrown 2,051 pitches that have been tracked by the PITCHf/x system between 2022 and 2025, including pitches thrown in the MLB Regular Season and Spring Training. In 2025, they have relied primarily on their Slider (79mph) and Fourseam Fastball (88mph), also mixing in a Sinker (88mph). He also rarely throws a Change (83mph).
In 2025, compared to other RHP:
Their slider comes in below hitting speed, sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball comes in below hitting speed, has heavy sinking action, has much less armside movement than typical and results in somewhat more groundballs compared to other pitchers' fourseamers. Their sinker has heavy sinking action, has surprisingly little armside run, has below average velo and generates fewer whiffs/swing compared to other pitchers' sinkers. Their change (take this with a grain of salt because they've only thrown 7 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slight cut action.
