In 2018, he relied primarily on his Fourseam Fastball (96mph) and Curve (81mph), also mixing in a Slider (85mph) and Sinker (95mph). He also rarely threw a Change (88mph) and Cutter (90mph).
Basic description of 2018 pitches compared to other RHP:
His fourseam fastball has slight armside run and has slightly above average velo. His curve has an exceptional bite, has sweeping glove-side movement and results in somewhat more groundballs compared to other pitchers' curves. His slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, sweeps across the zone, has exceptional depth and generates more whiffs/swing compared to other pitchers' sliders. His sinker (take this with a grain of salt because he's only thrown 6 of them in 2018) generates an extremely high number of swings & misses compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers, has well above average velo, has little sinking action compared to a true sinker and has slight armside run. His change (take this with a grain of salt because he's only thrown 14 of them in 2018) is much firmer than usual and has slight armside fade.
