His fourseam fastball has well above average velo, results in somewhat more flyballs compared to other pitchers' fourseamers, has slightly less natural movement than typical and has some added backspin.

His change results in more flyballs compared to other pitchers' changeups and is slightly firmer than usual. His sinker has surprisingly little armside run, has well above average velo, has little sinking action compared to a true sinker and results in somewhat more flyballs compared to other pitchers' sinkers. His curve has an exceptional bite, is an extreme flyball pitch compared to other pitchers' curves, generates more whiffs/swing compared to other pitchers' curves and has slight glove-side movement.
