Non-MLB
Although they have not thrown an MLB pitch in 2025, Jenrry Mejia threw 3,142 pitches that were tracked by the PITCHf/x system between 2010 and 2024, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2024, they relied primarily on their Cutter (88mph) and Slider (81mph), also mixing in a Change (84mph).
In 2024, compared to other RHP:
Their cutter (take this with a grain of salt because they've only thrown 17 of them in 2024) generates a very high amount of groundballs compared to other pitchers' cutters, generates more whiffs/swing compared to other pitchers' cutters and has little cutting action. Their slider (take this with a grain of salt because they've only thrown 8 of them in 2024) is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth, results in more flyballs compared to other pitchers' sliders and has below average velo. Their change (take this with a grain of salt because they've only thrown 5 of them in 2024) results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
