American golfer Webb Simpson maintained a four-stroke lead on Saturday in the Shriners Hospitals Open, with birdies on four of the last seven holes at TPC Summerlin in Las Vegas.

Making his first start since helping the United States to win the Presidents Cup, the 2012 US Open champion shot a four-under-par 67 to reach 19-under after three rounds. He opened with rounds of 64 and 63.

Chesson Hadley was second after a 67, reaching 15-under with an eagle on the par-5 16th, with Jeff Overton third – one shot further back – after a 68.

Jason Bohn had a 69 to reach 13-under and Sean O’Hair shot a 63 to join first-round leader JJ Henry, defending champion Ryan Moore, William McGirt, Ryo Ishikawa and Russell Knox at 12-under.

John Senden was the best of the Australians – eight strokes adrift of Simpson – on 202 after a third-round 71.

Senden was one clear of Stuart Appleby, who climbed up the leaderboard after a 65, followed by Greg Chalmers on 204 and a disappointing Geoff Ogilvy on 213.
