In 2025, compared to other LHP:
Their sinker has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, has well above average velo and has less armside run than typical. Their change is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone and is much firmer than usual. Their slider has exceptional depth and results in somewhat more flyballs compared to other pitchers' sliders. Their curve (take this with a grain of salt because they've only thrown 12 of them in 2025) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' curves, is an extreme flyball pitch compared to other pitchers' curves, has a sharp downward bite and has slight glove-side movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 7 of them in 2025) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has less armside movement than typical and has slightly above average velo.
