In 2023, compared to other RHP:
Their sinker (take this with a grain of salt because they've only thrown 4 of them in 2023) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has slight armside run. Their slider (take this with a grain of salt because they've only thrown 4 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement. Their cutter (take this with a grain of salt because they've only thrown 4 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has surprisingly little cutting action. Their fourseam fastball (take this with a grain of salt because they've only thrown 3 of them in 2023) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo and has slight armside run. Their change (take this with a grain of salt because they've only thrown 2 of them in 2023) is basically never swung at and missed compared to other pitchers' changeups, has an obvious armside fade, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
