Non-MLB
JC Ramírez has thrown 4,842 pitches that have been tracked by the PITCHf/x system between 2013 and 2025, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2025, they have relied primarily on their Fourseam Fastball (89mph), Curve (80mph) and Sinker (89mph). He also rarely throws a Splitter (89mph).
In 2025, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 9 of them in 2025) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has much less armside movement than typical and has below average velo. Their curve (take this with a grain of salt because they've only thrown 9 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' curves and is slightly harder than usual. Their sinker (take this with a grain of salt because they've only thrown 7 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has below average velo and has less armside run than typical. Their splitter (take this with a grain of salt because they've only thrown 1 of them in 2025) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' splitters, has an obvious armside fade, is an extreme flyball pitch compared to other pitchers' splitters and has movement that suggests a lot of backspin.
