In 2024, they relied primarily on their Fourseam Fastball (93mph) and Slider (83mph), also mixing in a Sinker (93mph) and Change (85mph).
In 2024, compared to other RHP:
Their fourseam fastball has heavy sinking action, generates a high number of swings & misses compared to other pitchers' fourseamers and has essentially average velo. Their slider results in more flyballs compared to other pitchers' sliders and has short glove-side cut. Their sinker has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers and has less armside run than typical. Their change dives down out of the zone and generates fewer whiffs/swing compared to other pitchers' changeups.
