For more than 10 years, Jimmy Walker had plugged away as a professional golfer before winning the 2013 Frys.com Open at age 34. It was his 188th start on the PGA Tour. Then it all fell into place.He won two more times in his next seven events. "He's definitely a late bloomer," says Butch Harmon, his teacher since 2011, "but he's also going to be around a long time."His performance so far this year suggests he will. Walker got into a playoff at the Hyundai Tournament of Champions, won the Sony Open in Hawaii and finished two back at the Farmers Insurance Open to take an early lead in the FedEx Cup standings. Last September, he was one of the U.S. team's few bright spots in his first Ryder Cup, winning 2½ points and defeating Lee Westwood in singles.The Baylor grad is also an amateur astronomer—he and his wife, Erin, even moved to a remote town near San Antonio for a better night sky. Walker is not your typical tour player. Harmon calls his swing "old school," which is just fine with them. "We didn't want to create a new swing, just take what he does naturally and make it better."
