Houston Astros
Nick Hernandez has thrown 2,800 pitches that have been tracked by the PITCHf/x system between 2020 and 2024, including pitches thrown in the MLB Regular Season and Spring Training. In 2024, they have relied primarily on their Slider (83mph) and Fourseam Fastball (92mph). He also rarely throws a Change (83mph) and Curve (74mph).
In 2024, compared to other RHP:
Their slider generates more whiffs/swing compared to other pitchers' sliders and results in somewhat more flyballs compared to other pitchers' sliders. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has less armside movement than typical, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their change is basically never swung at and missed compared to other pitchers' changeups and has some natural sink to it. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2024) is basically never swung at and missed compared to other pitchers' curves, has below average velo, results in more flyballs compared to other pitchers' curves and has little depth.
