5. Andres Romero
World rank: 24
Wins: 1 (6 others worldwide)
The young Argentine won in New Orleans this year, and he's the guy who should've won last year's British Open at Carnoustie. He turned a 10-birdie final round into a third-place finish thanks to a freak-bounce double bogey at the 17th and a failed up-and-down at the 18th. His career may well exceed that of Angel Cabrera, a fellow Argentine who won last year's U.S. Open.
