Non-MLB
Roman Mendez has thrown 1,396 pitches that have been 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 have relied primarily on their Fourseam Fastball (90mph), Splitter (83mph) and Slider (83mph).
In 2025, compared to other RHP:
Their fourseam fastball has heavy sinking action, has below average velo and has slight armside run. 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 slider (take this with a grain of salt because they've only thrown 15 of them in 2025) is an extreme flyball pitch compared to other pitchers' sliders and has less than expected depth.
