The 6’5 right-hander is committed to Miami, with Baseball America noting that “Marinan's slider flashes the sharp spin to project as at least an average offering, and he shows the ability to backdoor it to lefties or use it as a chase pitch away from righties.”
He touched 94-96 mph on his fastball at times as a senior. More from MLB.com:
He currently throws a hybrid breaking ball that gets stuck in between a slider and curveball, but looks more like the latter with some bite when it's on. Marinan will mix in an occasional changeup, but it's far behind the other two pitches. He stays around the strike zone and should have average control and command in the future.
