7. Jamie Lovemark, 19, U.S.
The Stats: The 6-foot-4 Californian, who plays at USC, had a breakout June, winning the NCAA title as a freshman and then losing the Nationwide Tour's Rochester Area Charities Showdown in a playoff as an amateur. He's three for three in making cuts on Tour, with his best finish a 39th at this year's Buick Invitational, where he had a first-round 66.
The Skinny: Could've easily turned pro after his hot run this summer, but he'll stay in school until at least next summer.
