Houston Astros
Although they have not thrown an MLB pitch in 2024, Penn Murfee threw 1,431 pitches that were tracked by the PITCHf/x system between 2022 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Slider (79mph) and Fourseam Fastball (88mph). He also rarely threw a Sinker (89mph).
In 2023, compared to other RHP:
Their slider comes in below hitting speed, sweeps across the zone, has exceptional depth, is an extreme flyball pitch compared to other pitchers' sliders and generates more whiffs/swing compared to other pitchers' sliders. Their fourseam fastball comes in below hitting speed, has heavy sinking action, has much less armside movement than typical and results in somewhat more flyballs compared to other pitchers' fourseamers. Their sinker (take this with a grain of salt because they've only thrown 8 of them in 2023) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has below average velo.
