In 2023, compared to other RHP:
Their sinker has surprisingly little armside run, generates more whiffs/swing compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers, has slightly below average velo and has some natural sinking action. Their slider is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has less than expected depth. Their change generates more whiffs/swing compared to other pitchers' changeups and results in more flyballs compared to other pitchers' changeups. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, is an extreme flyball pitch compared to other pitchers' fourseamers, has much less armside movement than typical and has below average velo. Their curve (take this with a grain of salt because they've only thrown 12 of them in 2023) is basically never swung at and missed compared to other pitchers' curves, has primarily 12-6 movement, is much harder than usual and results in more flyballs compared to other pitchers' curves.
