Non-MLB
Although they have not thrown an MLB pitch in 2024, Gabriel Ynoa threw 2,841 pitches that were tracked by the PITCHf/x system between 2016 and 2023, including pitches thrown in the MLB Regular Season and Fall/Winter Ball. In 2023, they relied primarily on their Fourseam Fastball (91mph) and Slider (82mph), also mixing in a Change (84mph). He also rarely threw a Sinker (92mph).
In 2023, compared to other RHP:
Their fourseam fastball has heavy sinking action, has an obvious tail, generates fewer whiffs/swing compared to other pitchers' fourseamers and has slightly below average velo. Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, is basically never swung at and missed compared to other pitchers' sliders, has below average velo, has primarily 12-6 movement and has some two-plane movement. Their change is basically never swung at and missed compared to other pitchers' changeups and has an obvious armside fade. Their sinker (take this with a grain of salt because they've only thrown 2 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' sinkers, has an obvious tail, is an extreme flyball pitch compared to other pitchers' sinkers and has some natural sinking action.
