Non-MLB
Although they have not thrown an MLB pitch in 2026, Ricardo Rincon threw 50 pitches that were tracked by the PITCHf/x system in 2008, all of them occuring in the MLB Regular Season. In 2008, they relied primarily on their Slider (82mph) and Change (85mph), also mixing in a Sinker (88mph). He also rarely threw a Fourseam Fastball (89mph).
In 2008, compared to other LHP:
Their slider generates a high number of swings & misses compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has less than expected depth. Their change (take this with a grain of salt because they've only thrown 15 of them in 2008) is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, is an extreme flyball pitch compared to other pitchers' changeups and is slightly firmer than usual. Their sinker (take this with a grain of salt because they've only thrown 8 of them in 2008) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slightly below average velo and has some natural sinking action. Their fourseam fastball (take this with a grain of salt because they've only thrown 1 of them in 2008) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has below average velo and has some natural sinking action.
