Non-MLB
Although they have not thrown an MLB pitch in 2024, Spencer Patton threw 3,453 pitches that were tracked by the PITCHf/x system between 2014 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Fourseam Fastball (91mph) and Slider (81mph). He also rarely threw a Change (84mph) and Sinker (91mph).
In 2023, compared to other RHP:
Their fourseam fastball has heavy sinking action, generates a high number of swings & misses compared to other pitchers' fourseamers, results in somewhat more flyballs compared to other pitchers' fourseamers, has slightly below average velo and has slightly less natural movement than typical. Their slider sweeps across the zone, has exceptional depth, has below average velo and results in somewhat more flyballs compared to other pitchers' sliders. Their change results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their sinker (take this with a grain of salt because they've only thrown 9 of them in 2023) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has less armside run than typical and has some natural sinking action.
