Non-MLB
Although they have not thrown an MLB pitch in 2025, Tyler Viza threw 513 pitches that were tracked by the PITCHf/x system between 2023 and 2024, including pitches thrown in The World Baseball Classic and Fall/Winter Ball. In 2024, they relied primarily on their Fourseam Fastball (89mph), also mixing in a Slider (81mph) and Change (83mph).
In 2024, compared to other RHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has below average velo, generates fewer whiffs/swing compared to other pitchers' fourseamers and has some natural sinking action. Their slider (take this with a grain of salt because they've only thrown 18 of them in 2024) is basically never swung at and missed compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their change (take this with a grain of salt because they've only thrown 15 of them in 2024) 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.
