Kostyshock

3/15/19:�Slender built with a super quick arm at 6-foot-5, 195 pounds, Kostyshock entered Friday's game as the setup man in the eighth inning for the Razorbacks. The ball jumped out of his hand as he threw 95-96 mph bolts to the plate from a three-quarter slot. His 84-86 mph sweeping slider didn't have the same abrupt action as it did last summer in the Northwoods, but it was still effective as a second pitch to his electric heater. He is a late developing arm with velocity that is likely to continue to grow. (Seifert)
