Their sinker (take this with a grain of salt because they've only thrown 5 of them in 2023) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers and is an extreme flyball pitch compared to other pitchers' sinkers. Their change (take this with a grain of salt because they've only thrown 2 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone, results in more flyballs compared to other pitchers' changeups, is slightly firmer than usual and has slight armside fade. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2023) is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth, is an extreme flyball pitch compared to other pitchers' sliders and has below average velo. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2023) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has strong cutting action.
