In 2025, compared to other RHP:
Their slider has exceptional depth and results in many more groundballs compared to other pitchers' sliders. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, results in somewhat more groundballs compared to other pitchers' fourseamers, has slightly above average velo and has slightly less natural movement than typical. Their curve (take this with a grain of salt because they've only thrown 16 of them in 2025) has an exceptional bite, generates an extremely high number of swings & misses compared to other pitchers' curves and results in more flyballs compared to other pitchers' curves. Their sinker (take this with a grain of salt because they've only thrown 13 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 above average velo. Their change (take this with a grain of salt because they've only thrown 4 of them in 2025) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2025) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has surprisingly little cutting action.
