Their fourseam fastball has heavy sinking action, is an extreme flyball pitch compared to other pitchers' fourseamers, has slightly below average velo and has slightly less natural movement than typical. Their splitter has dives down out of the zone, generates a high number of swings & misses compared to other pitchers' splitters, results in somewhat more flyballs compared to other pitchers' splitters and has slightly below average velo. Their slider (take this with a grain of salt because they've only thrown 19 of them in 2026) is an extreme flyball pitch compared to other pitchers' sliders, has short glove-side cut and has below average velo.
