|Purke rivals Tyler Matzek as the best lefthanded pitching prospect in this draft. He already throws a 92-95 mph fastball and could throw harder as he adds strength to his 6-foot-3, 180-pound frame. He backs up his heater with a hard slider that ranks among the best in the prep draft class. He doesn't have much experience throwing a changeup because he hasn't needed one. Last summer, Purke needed just nine pitches to work a perfect inning at the Aflac All-American Game and started the gold-medal game for Team USA at the World Junior Championship in Canada (albeit taking a 7-0 loss against Korea). Matzek has moved ahead of Purke for most clubs because he works with less effort. Purke throws from a low three-quarters angle that adds life and deception, but he has slinging action in his delivery. It's not violent, but it's not smooth either. Purke's stuff, track record and strong makeup combine to make him an upper-first-round talent, though teams still were trying to gauge his signability. If he follows through on his commitment to Texas Christian, he'd be eligible again as a sophomore in 2011.
