In 2026, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slightly less natural movement than typical. Their slider results in more flyballs compared to other pitchers' sliders. Their curve (take this with a grain of salt because they've only thrown 14 of them in 2026) results in more flyballs compared to other pitchers' curves and has a sharp downward bite. Their sinker (take this with a grain of salt because they've only thrown 10 of them in 2026) is basically never swung at and missed compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 7 of them in 2026) is basically never swung at and missed compared to other pitchers' changeups, is much firmer than usual and results in more flyballs compared to other pitchers' changeups.
