Their fourseam fastball comes in below hitting speed, results in somewhat more flyballs compared to other pitchers' fourseamers and has slight armside run. Their curve has an exceptional bite, comes in below hitting speed, has sweeping glove-side movement and results in somewhat more flyballs compared to other pitchers' curves. Their change has below average velo and results in somewhat more flyballs compared to other pitchers' changeups. Their cutter comes in below hitting speed, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has little cutting action. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2017) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders.
