Kopercinski provided the highest fastball velocity amongst any left-handed at the event, pitching at 81-83 and touching 84. The athletic, 5-foot-9, 160 pounder is another young one in this class, and his arm speed stands as his best attribute. It is a violent operation with a bit of quirk to it, but the fastball really jumps out and the higher frontside should create a deceptive look.
