Non-MLB
Although they have not thrown an MLB pitch in 2024, Jorge Rondon threw 382 pitches that were tracked by the PITCHf/x system between 2014 and 2016, all of them occuring in the MLB Regular Season. In 2016, they relied primarily on their Fourseam Fastball (97mph) and Slider (89mph), also mixing in a Sinker (96mph).
In 2016, compared to other RHP:
Their fourseam fastball is an extreme flyball pitch compared to other pitchers' fourseamers, is blazing fast, has some natural sinking action and has slight armside run. Their slider is thrown extremely hard, is an extreme flyball pitch compared to other pitchers' sliders and generates fewer whiffs/swing compared to other pitchers' sliders. Their sinker (take this with a grain of salt because they've only thrown 4 of them in 2016) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, is blazing fast, has slight armside run and has some natural sinking action.
