Non-MLB
Although they have not thrown an MLB pitch in 2024, Carlos Rosa threw 615 pitches that were tracked by the PITCHf/x system between 2008 and 2011, including pitches thrown in the MLB Regular Season and Spring Training. In 2011, they relied primarily on their Fourseam Fastball (95mph) and Slider (88mph), also mixing in a Change (87mph).
In 2011, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 10 of them in 2011) is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has slightly above average velo. Their slider (take this with a grain of salt because they've only thrown 7 of them in 2011) is thrown extremely hard and is an extreme flyball pitch compared to other pitchers' sliders. Their change (take this with a grain of salt because they've only thrown 1 of them in 2011) is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, is slightly firmer than usual and has some natural sink to it.
