Non-MLB
Although they have not thrown an MLB pitch in 2024, Lester Oliveros threw 539 pitches that were tracked by the PITCHf/x system between 2011 and 2014, all of them occuring in the MLB Regular Season. In 2014, they relied primarily on their Fourseam Fastball (95mph), also mixing in a Slider (84mph). He also rarely threw a Change (81mph).
In 2014, compared to other RHP:
Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has slightly above average velo and has slightly less natural movement than typical. Their slider is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement. Their change (take this with a grain of salt because they've only thrown 4 of them in 2014) is basically never swung at and missed compared to other pitchers' changeups, has below average velo, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it.
