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.
