His sinker has an obvious tail and has slightly above average velo. His fourseam fastball has essentially average velo and has slight armside run. His slider is thrown extremely hard, has much less depth than expected, has primarily 12-6 movement and generates fewer whiffs/swing compared to other pitchers' sliders. His curve is slightly harder than usual and has primarily 12-6 movement. His change has a lot of backspin, is slightly firmer than usual and has slight armside fade.
