Kevin Na birdied holes 15, 16, and 17 and parred the 18th to stay at 23 under and hold off Nick Watney and win the Justin Timberlake Shriners Hospitals for Children Open on Sunday at TPC Summerlin. Na, a Las Vegas-area resident, has been close many times before but never broken through with that first victory. Making his 132nd career start, Na put together rounds of 66-65 on the weekend to break out of ties following the second and third rounds. The victory moves Na to 33 on the PGA TOUR money list.
