Their fourseam fastball has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers and has well above average velo. Their slider (take this with a grain of salt because they've only thrown 14 of them in 2026) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. Their sinker (take this with a grain of salt because they've only thrown 12 of them in 2026) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers, has well above average velo and has slight armside run. Their splitter (take this with a grain of salt because they've only thrown 3 of them in 2026) is thrown extremely hard, has dives down out of the zone, is basically never swung at and missed compared to other pitchers' splitters, has surprising cut action and is an extreme flyball pitch compared to other pitchers' splitters.
