Rory McIlroy produced a stunning third-round 62 - his lowest since 2019 - to shoot to second on the CJ Cup leaderboard ahead of Sunday's final round.
The Holywood golfer was in sensational form, and a blemish-free card that saw him manage eight birdies and an eagle on his final hole saw him move to 19 under par and briefly top of the leaderboard, before Rickie Fowler established a two-shot advantage at the Summit Club.
The American finished an impressive round with a 63, with five front nine birdies and four more coming home, to take a two-shot lead on 21 under ahead of McIlroy, who is a further stroke clear of the trio of Abraham Ancer, Adam Scott and Robert Streb.
Shane Lowry shot an under-par 69 to move on to four under, but he remains outside the top 70.
Consecutive double bogeys at the eighth and ninth hole had seen overnight leader Kevin Mitchell fall down the leaderboard in Las Vegas.
There were no such worries for McIlroy though, as he produced one of his best nine holes in some time, with birdies arriving in six of his seven holes between the third and ninth holes.
The back nine was quieter, comparatively speaking, but McIlroy picked up shots at the 12th and 14th before signing off in tremendous fashion as his approach on the 18th landed seven yards from the hole for an eagle.
The former world number one who has this year dropped to 14th in the rankings, later said he could not remember his last bogey-free round before this tournament, where he suddenly has two.
"I think on a course like this you're going to have stretches where you're going to play good golf and hit good shots and maybe just not hole the putts," he told reporters.
"I played an eight-hole stretch yesterday in even par - I made eight pars in a row. Then today, I played nine holes in six under and all of a sudden you feel a little better about yourself."
