In 2025, compared to other LHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their slider results in more flyballs compared to other pitchers' sliders and has some two-plane movement. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters and results in somewhat more flyballs compared to other pitchers' cutters. Their curve (take this with a grain of salt because they've only thrown 19 of them in 2025) is basically never swung at and missed compared to other pitchers' curves, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves. Their change (take this with a grain of salt because they've only thrown 14 of them in 2025) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, has slight cut action and is slightly firmer than usual. Their sinker (take this with a grain of salt because they've only thrown 8 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has slightly below average velo.
