Non-MLB

In 2023, they relied primarily on their Fourseam Fastball (92mph), also mixing in a Slider (81mph).
In 2023, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 16 of them in 2023) generates a high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo, has slightly less natural movement than typical and has some added backspin. Their slider (take this with a grain of salt because they've only thrown 4 of them in 2023) is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth, is an extreme flyball pitch compared to other pitchers' sliders, has short glove-side cut and has below average velo.
