Colorado Rockies
Although they have not thrown an MLB pitch in 2026, Juan Mejia threw 1,485 pitches that were tracked by the PITCHf/x system between 2023 and 2025, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2025, they relied primarily on their Fourseam Fastball (97mph) and Slider (83mph). He also rarely threw a Change (92mph).
In 2025, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, has much less armside movement than typical, has well above average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider sweeps across the zone, has exceptional depth and results in more flyballs compared to other pitchers' sliders. Their change (take this with a grain of salt because they've only thrown 7 of them in 2025) is thrown extremely hard, 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.
