Peter Uihlein leads in Las Vegas; Jordan Spieth 3 shots back

LAS VEGAS -- Peter Uihlein topped the leaderboard at 8-under 63 on Thursday in the Shriners Hospitals For Children Open, with Jordan Spieth 3 strokes back in his season debut.

Uihlein birdied six of his final nine holes in the morning round at TPC Summerlin.

Seth Reeves shot 64, electing to finish the par-5 ninth after the horn sounded suspending play because of darkness. Harold Varner III and Robert Streb were 2 strokes back at 65.

Spieth followed at 66 in his first career start in a domestic fall event. Fellow U.S. Ryder Cup player Bryson DeChambeau also was at 66 with Si Woo Kim, Whee Kim, Sebastian Munoz, Sam Ryder and Abraham Ancer.
