Their fourseam fastball has some natural sinking action, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their change generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone and has slightly below average velo. Their slider is basically never swung at and missed compared to other pitchers' sliders. Their cutter (take this with a grain of salt because they've only thrown 3 of them in 2025) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has some natural sink.
