Non-MLB
Although they have not thrown an MLB pitch in 2024, Alex Colomé threw 9,678 pitches that were tracked by the PITCHf/x system between 2013 and 2023, including pitches thrown in the MLB Regular Season, Spring Training and Fall/Winter Ball. In 2023, they relied primarily on their Cutter (91mph) and Fourseam Fastball (94mph). He also rarely threw a Change (90mph) and Curve (85mph).
In 2023, compared to other RHP:
Their cutter is a real worm killer that generates an extreme number of groundballs compared to other pitchers' cutters, generates a high number of swings & misses compared to other pitchers' cutters, has well above average velo and has some natural sink. Their fourseam fastball has less armside movement than typical, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. Their change is thrown extremely hard, has surprising cut action, has a lot of backspin and results in somewhat more flyballs compared to other pitchers' changeups. Their curve (take this with a grain of salt because they've only thrown 4 of them in 2023) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth and has slight glove-side movement.
