In 2019, they relied primarily on their Sinker (93mph), also mixing in a Slider (87mph). He also rarely threw a Change (88mph).
In 2019, compared to other RHP:
Their sinker generates a high number of swings & misses compared to other pitchers' sinkers, results in somewhat more groundballs compared to other pitchers' sinkers and has slightly above average velo. Their slider is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has primarily 12-6 movement. Their change (take this with a grain of salt because they've only thrown 4 of them in 2019) generates an extremely high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has slight armside fade.
