By Bill Cooney, PGATOUR.COM Vijay Singh thinks he has the solution to the problematic putting that has plagued him on Sundays. After carding a 5-under 66 in the third round of the Frys.com Open on Saturday at CordeValle in San Martin, Calif., Singh said that he recently changed his putting grip and feels more confident with it. Singh, looking for his first win on the PGA TOUR since 2008, has contended multiple times this season until fading on Sunday. "The problem was my putting on the weekend," said Singh, who ranks 175th in strokes gained-putting this season but is 12th in that category this week. "I felt really weird with my putting stroke. It worked good for two days and (did not) under the gun. But this week has been looking good. I've changed my grip a little bit and it's flowing really freely. So that's a big plus." Singh ranks 18th on the PGA TOUR with a 70.20 scoring average in the first two rounds. But his final-round scoring average of 72.14 ranks 151st. Singh put himself in position for another run at a title with an incredible drive on the reachable par-4 17th. His drive ended 5 feet from the hole and he made the eagle putt. He made par on the 18th and finished at 11 under for the tournament -- within striking distance of the lead. "I think I can still play," said Singh, who turns 50 in February. "That’s the key. If I thought that I didn’t have it I’d hang up the visor. ... Going out there and knowing that I can win every week -- that’s what keeps me going." Afterward during an interview with Golf Channel, Singh was asked if he thought he had lived up to his expectations on the TOUR, given that he is making his 500th start this week. Singh has 34 career PGA TOUR wins -- including three major championships -- and won the 2008 FedExCup. "If you look at the starts I’ve had and the wins I’ve had, no I have not," Singh told Golf Channel. "I wish my percentage was a little better. Yes and no. I think I can do a lot better, could have done a lot better and I still can. ... I’m just enjoying it. My body feels good. I feel strong and I’m looking forward to the rest of the year." And Sundays, too.
