Non-MLB
Although they have not thrown an MLB pitch in 2024, Arquimedes Caminero threw 2,530 pitches that were tracked by the PITCHf/x system between 2013 and 2016, including pitches thrown in the MLB Regular Season and Spring Training. In 2016, they relied primarily on their Fourseam Fastball (99mph) and Cutter (92mph), also mixing in a Sinker (98mph) and Splitter (91mph). He also rarely threw a Slider (81mph).
In 2016, compared to other RHP:
Their fourseam fastball has heavy sinking action, is thrown at a speed that's borderline unfair and results in somewhat more groundballs compared to other pitchers' fourseamers. Their cutter is blazing fast, has some natural sink and has strong cutting action. Their sinker is thrown at a speed that's borderline unfair and has some natural sinking action. Their splitter is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' splitters, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' splitters, has some natural sink to it and has slight armside fade. Their slider (take this with a grain of salt because they've only thrown 5 of them in 2016) is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, has exceptional depth, is an extreme flyball pitch compared to other pitchers' sliders and has below average velo.
