His sinker has heavy sinking action, has slight armside run and has slightly above average velo. His cutter has well above average velo and has some natural sink. His fourseam fastball has heavy sinking action and has essentially average velo. His change dives down out of the zone, is much firmer than usual and has slight armside fade. His slider is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, has exceptional depth and results in somewhat more groundballs compared to other pitchers' sliders.
