In 2024, compared to other LHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has much less armside movement than typical, has some natural sinking action and has essentially average velo. Their slider has some two-plane movement. Their curve has a sharp downward bite and has slightly below average velo. Their change is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
