Tyrrell Hatton was three shots off the pace in second place at the halfway mark of the CJ Cup PGA tournament in Last Vegas on Friday.
Hatton could not quite match his first round of seven-under 65, but still managed to card a four-under 68 to be 11-under par behind American Xander Schauffele, who made six birdies in a row amid a 64 to be 14-under.
Meanwhile Rory McIlroy had a rollercoaster of a second day at Shadow Creek - seven birdies were offset by four bogeys as he posted a three under par round of 69.
Further down the leaderboard, Shane Lowry is in a share of 52nd place on two over par following a second round of 74.
The 29-year-old Hatton had an eventful day, with seven birdies offset by three bogeys.
He carried on from his two-shot overnight lead with birdies on the fourth, seventh and eighth, to turn in three-under 33 and a formidable 10-under for the tournament.
In unusual scenes, Hatton had to re-situate his ball in a greenside bunker on the 11th after playing partner Jon Rahm’s divot landed on it. He chipped out to eight feet but took two putts for bogey.
He recovered with birdie threes on the 12th and 14th holes, before ending with a run of bogey-bogey-birdie-birdie.
Schauffele enjoyed the tournament’s lowest round so far with his remarkable 64. After birdying his second hole he then unleashed his incredible streak of birdies from his fourth to his ninth, to turn with a seven-under 29.
Yet he was then able to add just one more birdie on his way home, against eight pars.
Lying third, a shot behind Hatton, was American Russell Henley, while England’s Matthew Fitzpatrick was seven shots off the lead on seven-under.
Ian Poulter shot a two-under 70 to be in a tie for 13th at five-under and Justin Rose was on two-over after rounds of 74 and 72.
