Smylie Kaufman won the Shriners Hospitals for Children Open on Sunday in his fifth PGA Tour start, shooting a 10-under 61 and waiting more than two hours to see if anyone could catch him.
Kaufman played the final 11 holes in nine under with an eagle and seven birdies.
The 23-year-old former LSU player set up the eagle with a three-wood drive to 15 feet on the par-4 15th and closed with a 20-foot birdie putt on the par-4 18th to post 16-under 268 at TPC Summerlin.
Kevin Na, third-round leader Brett Stegmaier, Patton Kizzire, Cameron Tringale, Jason Bohn and Alex Cejka tied for second, a stroke back.
Na, coming off playoff loss last week to Emiliano Grillo in the season-opening event in Napa, California, made a 25-foot birdie putt on the par-5 16th to tie for the lead, but bogeyed the par-3 17th after mishitting a chip, and missed a 15-foot birdie try on 18.
