LAS VEGAS (AP) Canada's David Hearn birdied his final three holes in perfect morning conditions for a 7-under 64 and a share of the lead Thursday in the Shriners Hospitals for Children Open.
Michael Thompson, Mark Hubbard and Tyler Aldridge also topped the leaderboard at TPC Summerlin. Aldridge had two holes left when first-round play was suspended because of darkness.
Patrick Rodgers, Patton Kizzire, Chad Campbell, Ryan Palmer, Ricky Barnes, D.H. Lee, Ryo Ishikawa, Greg Owen, Shane Bertsch and Brendon Todd shot 65, and Henrik Norlander also was 6 under with two holes left.
Kizzire is making his first start as a PGA Tour member after winning twice last year on the Web.com Tour and topping the regular-season and finals-combined money lists. He was married Saturday.
Jimmy Walker opened with a 66, and U.S. Presidents Cup teammate Rickie Fowler had a 72.
