His fourseam fastball is straight as an arrow, generates a very high amount of groundballs compared to other pitchers' fourseamers, has some natural sinking action and has slightly above average velo. His slider has exceptional depth, has short glove-side cut and results in somewhat more groundballs compared to other pitchers' sliders. His sinker has surprisingly little armside run, results in many more groundballs compared to other pitchers' sinkers and has slightly above average velo. His change is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action and results in somewhat more flyballs compared to other pitchers' changeups.
