Patrick Cantlay fired a Saturday-best 60 to climb into a tie for the lead with Tom Kim after three rounds of the Shriners Children's Open in Las Vegas.
Kim carded a solid 62 himself at TPC Summerlin to join Cantlay at 19-under as the pair hold a three-stroke lead heading into Sunday's final round.
Second-round leader Mito Pereira and Matthew NeSmith are tied for third at 16 under. South Koreans Sungjae Im and Seonghyeon Kim are four shots off the lead.
Cantlay played a superb round, opening his round with four straight birdies enroute to 11 on the day and turning in a clean card.
"I was really happy with today. I played great," Cantlay said. "Had a bunch of looks and made most of them. I hit good putts all day today. You can't make every single one as much as you'd like to. I'm very happy with how I played, and I'm in a good spot going into tomorrow."
Kim played bogey-free golf as well, recording just two birdies fewer than Cantlay. Kim birdied five of his last six holes.
"I took care of what I really needed to take care of on this golf course and just needing a good round to give myself a chance on Sunday really because I'm really happy with myself just keeping it tight," said Kim, who added he wasn't leaderboard-watching to see what Cantlay was doing.
Ireland's Seamus Power missed the cut by a single shot on Friday.
