Basic description of 2019 pitches compared to other LHP:
His sinker generates a high number of swings & misses compared to other pitchers' sinkers, has well above average velo and results in somewhat more flyballs compared to other pitchers' sinkers. His change dives down out of the zone, is slightly firmer than usual and has slight armside fade. His curve has sweeping glove-side movement and is slightly harder than usual. His slider is thrown extremely hard, is basically never swung at and missed compared to other pitchers' sliders, has primarily 12-6 movement, results in many more groundballs compared to other pitchers' sliders and has less than expected depth.
