BETA Feature:
Basic description of 2018 pitches compared to other RHP:
His fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers and is thrown at a speed that's borderline unfair. His slider is thrown extremely hard, generates a high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement. His curve is thrown extremely hard, has an exceptional bite and results in somewhat more flyballs compared to other pitchers' curves. His change generates an extremely high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in somewhat more flyballs compared to other pitchers' changeups and has slight armside fade. His sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers and has little sinking action compared to a true sinker.
