In 2026, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 8 of them in 2026) results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slightly less natural movement than typical. Their change (take this with a grain of salt because they've only thrown 5 of them in 2026) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone and results in more flyballs compared to other pitchers' changeups. Their slider (take this with a grain of salt because they've only thrown 5 of them in 2026) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has less than expected depth and has primarily 12-6 movement. Their sinker (take this with a grain of salt because they've only thrown 1 of them in 2026) 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.
