In 2019, they relied primarily on their Fourseam Fastball (93mph) and Slider (86mph), also mixing in a Splitter (84mph).
In 2019, compared to other RHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has essentially average velo. Their slider generates a high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has primarily 12-6 movement. Their splitter (take this with a grain of salt because they've only thrown 6 of them in 2019) has dives down out of the zone, is basically never swung at and missed compared to other pitchers' splitters, has surprising cut action and is an extreme flyball pitch compared to other pitchers' splitters.
