Kevin Na won the Justin Timberlake Shriners Hospitals for Children Open Sunday for his first PGA Tour title, hitting three birdies near the end of his round to pull away for a two-stroke victory over Nick Watney. The 28-year-old Na closed with a 6-under 65 for a tournament-record 23-under 261 total at TPC Summlerin in the Fall Series opener. Watney, a two-time winner this year, shot a 67. Tied for the lead with Watney entering the round, Na sealed the breakthrough victory with a 42-foot birdie putt on the par-3 17th. Na and Watney both parred the par-4 18th. “I'm just very excited about my first win,” said Na, who starting playing golf a year after his family moved to the United States from South Korea when he was 8. The winner had five birdies and a bogey on the front nine to reach 21-under. He parred the first four holes on the back nine, then dropped a stroke on the par-3 14th to fall into a tie with Watney. “I hit a terrible shot on 14,” Na said. “I should have backed off. I always back off, but I felt, ‘I'm going to hit this.' And I hit a terrible shot and made bogey. “To bounce back after that bogey, to hit that chip to 3 feet – I had a great chip from down there – I was able to relax a little bit. Then I had a great two-putt for birdie on the next hole. It gave me a one-shot lead. I told myself par, par, you're going to win this golf tournament.” Na pulled ahead with his birdie on the par-4 15th and both players birdied the par-5 16th. Tommy Gainey and Paul Goydos had 68s to tie for third at 18-under, and David Hearn (65), Carl Pettersson (68), Jhonattan Vegas (68), Tim Herron (69) and Spencer Levin (68) followed at 17 under. Na and Watney broke the record by two strokes in the event that switched from 90 to 72 holes in 2004.
