His fourseam fastball has less armside movement than typical and has slightly above average velo. His curve has an exceptional bite and has slight glove-side movement. His change is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. His slider sweeps across the zone, has exceptional depth and results in more flyballs compared to other pitchers' sliders.
