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 Sinker (89mph) and Curve (80mph), also mixing in a Fourseam Fastball (89mph).
In 2025, compared to other RHP:
Their sinker (take this with a grain of salt because they've only thrown 12 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 surprisingly little armside run 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 fourseam fastball (take this with a grain of salt because they've only thrown 5 of them in 2025) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is straight as an arrow and is an extreme flyball pitch compared to other pitchers' fourseamers.
