Non-MLB
Although they have not thrown an MLB pitch in 2026, Roman Mendez threw 1,463 pitches that were tracked by the PITCHf/x system between 2012 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 (90mph), Slider (83mph) and Splitter (83mph). He also rarely threw a Sinker (91mph).
In 2025, compared to other RHP:
Their fourseam fastball has heavy sinking action, has below average velo, results in somewhat more groundballs compared to other pitchers' fourseamers and has slight armside run. Their slider results in more flyballs compared to other pitchers' sliders and has less than expected depth. Their splitter generates an extremely high number of swings & misses compared to other pitchers' splitters, results in more flyballs compared to other pitchers' splitters and has slightly below average velo. Their sinker (take this with a grain of salt because they've only thrown 4 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers and is an extreme flyball pitch compared to other pitchers' sinkers.
