In 2018, compared to other LHP:
Their fourseam fastball has much less armside movement than typical, has some natural sinking action, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, has less armside run than typical and has some natural sinking action. Their slider sweeps across the zone, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their change generates a very high amount of groundballs compared to other pitchers' changeups, is much firmer than usual and has some natural sink to it. Their curve has an exceptional bite, has below average velo and has slight glove-side movement.
