Standing in at 6-foot-3, 180 pounds, Haynes has an excellent pitcher’s frame. He pitches with a heavy 84-88 mph fastball from a high ¾ slot, and also showed a little more later in the tournament, running his fastball up to 89 mph. When he stays over the rubber he gets through his slight stab a little more consistently. His curveball flashes shape at 71-73 mph and also features a changeup at 72-74 mph. This is a good-bodied kid with some nice upside to an already maturing arsenal.
