LAS VEGAS — Two weeks into the new season, rookies are ruling the PGA Tour.

Smylie Kaufman became the second straight rookie to win Sunday when he closed with a 10-under 61 and then waited more than two hours to see if anyone could catch him in the Shriners Hospital for Children Open.

That felt tougher than any of the seven birdies and one eagle he made over the final 11 holes at the TPC Summerlin.

“I dodged a lot of bullets coming down the stretch with guys coming,” Kaufman said after his one-shot victory.

Kaufman, a 23-year-old from LSU, played the last four holes in 4 under. That included his 3-wood to 15 feet for eagle on the par-4 15th, and a 20-foot birdie putt on the final hole.
