6. Ryan Moore, 24, U.S.
The Stats: The Tacoma, Wash., native was one of the most decorated amateurs in history. In the 2004 season, he took the U.S. Amateur, the U.S. Public Links, the NCAAs, the Western Amateur and the Sahalee Players. He had no formal lessons growing up but was taught by his father, Mike, the general manager of a golf course. His streaky Tour career has included three seconds and 15 other top 25s, but also 25 missed cuts in 65 total starts.
The Skinny: Turned pro with huge expectations. After three solid-but-winless years of cashing checks, he's got to be wondering if goodness, rather than greatness, will define his career.
