Non-MLB
Although they have not thrown an MLB pitch in 2024, Rhiner Cruz threw 1,473 pitches that were tracked by the PITCHf/x system between 2012 and 2023, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2023, they relied primarily on their Fourseam Fastball (92mph), also mixing in a Change (84mph). He also rarely threw a Slider (81mph).
In 2023, compared to other RHP:
Their fourseam fastball has some natural sinking action, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their change (take this with a grain of salt because they've only thrown 3 of them in 2023) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it. Their slider (take this with a grain of salt because they've only thrown 1 of them in 2023) is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, has short glove-side cut, has below average velo and has some two-plane movement.
