| Summary: Before Tommy John surgery halted his ascent, Perales had emerged as one of Boston’s most electric young arms. The Venezuelan right-hander features a deep four-pitch mix built around a 95–98 mph fastball that can touch triple digits with explosive carry up in the zone. His upper-80s splitter shows plus tumble and consistent bat-missing action, giving him a legitimate out pitch against both sides. A low-90s cutter and mid-80s slider each flash above-average, the former inducing weak contact and the latter showing sharper spin and shape prior to the injury. Compact and athletic, he creates big velocity from a smaller frame through fast arm speed and late whip. Perales showed real command gains before the injury—cutting his walk rate nearly in half—and reached Double-A as a 21-year-old. The injury paused what looked like a breakout, and he has struggled with command again in limited innings since returning, but his combination of stuff, athleticism, and feel for four distinct weapons still gives him mid-rotation potential. Should durability concerns persist, the power arsenal and mound presence would translate easily to a late-inning relief role, where the fastball/splitter combo could dominate in shorter bursts. | |||||||||||
