08/24/2013 - Under Armour All-America Game, powered by Baseball Factory On Thursday, in the gym during the instructional clinic the players did for local youth teams, Dylan was effortlessly dunking a baseball during breaks while the groups rotated. It was in impressive display of pure athletic ability. This goes a long way to explain how he generates mid to upper 90s velocity. His delivery is athletic and fluid, and his arm works with looseness back and through. The ball gets out of his hand with great life, allowing for electric stuff at times. He topped at 97 witt the fastball, and spun a low to mid 70s breaking ball. I also saw a change at 80. He started the game for the American team, and notched a scoreless first inning in which he allowed no hits, no walks and struck out one. While his fastball was as impressive as I've seen, he didn't show the knockout breaking ball today - just didn't get out in front with it enough.
