LAS VEGAS — Tom Kim closed with a 5-under 67 and completed a bogey-free week in Las Vegas to win the Shriners Children's Open when Patrick Cantlay fell apart on the final hole Sunday.

Kim became the first player since Tiger Woods in 1996 to win twice on the PGA Tour before turning 21. The 20-year-old South Korean won the Wyndham Championship in August to earn a tour card and he's been soaring ever since.

“I'm having fun playing on the PGA Tour. It's awesome,” Kim said.

But he needed some help from Cantlay, who could have gone to No. 2 in the world with a win at the TPC Summerlin.

They traded birdies along the back nine and came to the par-4 18th hole tied for the lead when it all fell apart for Cantlay. He was first to play and hooked a 3-wood left of the fairway into a desert bush in a ravine.

Kim belted driver into the fairway and by the time he finally played his second shot to the green, Cantlay was lying four in the bottom of the pond.

Cantlay tried blasting out of the bush to no avail. He took a penalty drop. He then hit out of the desert sand and into the pond. Cantlay finished with a 35-foot putt for triple bogey for a 69 that gave him a share of second place with Matthew NeSmith (66).

“I figured the only chance I had was to get it in the fairway,” Cantlay said about his decision to try to play from out of the bush. "I played well — one bad swing at the end. Obviously, I would have liked to have closed the deal out today, but sometimes that's golf.

Kim became the first player since J.T. Poston at the 2019 Wyndham Championship to win a PGA Tour event without making bogey. The way the back nine was going, no one could afford to drop any shots.

Cantlay birdied the 11th and 12th to tie Kim for the lead. Kim responded with birdies on the next two holes to restore a two-shot lead. Cantlay had 30-foot eagle chances on the next two holes, driving the par-4 14th green with a 3-wood and reaching the par-5 15th in two, while Kim had to settle for pars.

Cantlay's 35-foot putt for triple bogey was worth $160,000, but that was small consolation. It was his third disappointment in Las Vegas, the site of his first PGA Tour win. He lost in a playoff to Kevin Na in 2019 and had a share of the 54-hole lead the following year until a poor final round to tie for eighth.

“I hit a lot of good shots,” Cantlay said. “Obviously, the last hole makes the whole week kind of sour.”

That left Kim a somewhat muted celebration.

“I played solid this week — no bogey for 72 holes,” Kim said. “I got very lucky on the 18th, I'm not going to lie. Patrick played awesome, and to come out with a win I feel fortunate.”

Adam Hadwin of Abbotsford, B.C., finished tied for 10th, seven shots back of the winner. Taylor Pendrith of Richmond Hill, Ont., finished tied for 44th at 11 under. Adam Svensson of Surrey, B.C., tied for 69th at 7 under.

Woods was 20 when he won in Las Vegas and then at Disney in just seven tournaments since turning pro. Kim now is the second-youngest player to win two PGA Tour events before turning 21, a month behind Ralph Guldahl when he won the 1932 Arizona Open for his second win.

It's been quite the year for Kim, who honed his golf in Australia and the Philippines before turning pro. He started this year by winning the Singapore International and finishing runner-up in the Singapore Open on the Asian Tour.

After winning the Wyndham Championship, he made his debut in the Presidents Cup by going 2-3-0 for the International team and delivering one of the biggest moments with a 10-foot birdie putt in fourballs in a 1-up win over Cantlay and Xander Schauffele.

Next up is the Zozo Championship in Japan for Kim, who goes to No. 15 in the world and becomes the highest-ranked Asian player, moving ahead of Hideki Matsuyama of Japan.
