Im Sung-jae enjoyed a red-hot finish to claim the Shriners Children's Open title by four strokes on Sunday.

South Korean golfer Im rode a wave of nine birdies in a flawless final-round 62 to clinch his second PGA Tour crown.

Im – who eclipsed his personal record of birdies in a round – did not drop a shot at TPC Summerlin on the final day as the 23-year-old blitzed the field in Las Vegas.

With the win, Im has now triumphed in his 50th PGA Tour career start (2020 Honda Classic) and 100th (2021 Shriners Children's Open).

"I didn't have to worry about the wind, and I stayed relaxed the whole day," he said. "My driver, irons and putter came through when I needed them the most."

Im finished 24 under overall through 72 holes, ahead of American Matthew Wolff (68).

Marc Leishman (63), Rory Sabbatini (64) and overnight leader Adam Schenk (70) ended the tournament in a tie for third at 19 under.

Defending champion Martin Laird finished tied for 11th and eight strokes off the pace following his five-under-par 66.

As for four-time major winner Brooks Koepka, his final-round 73 saw him fall 20 shots behind and level alongside Masters champion Hideki Matsuyama (72) in a tie for 67th position.

Adam Schenk had a day to remember as he moved top of the Shriners Children's Open leaderboard by one stroke following a red-hot finish to his third round.

American golfer Schenk carded a five-under-par 66 to hit the front at the PGA Tour tournament in Las Vegas on Saturday.

Searching for his first PGA Tour title, the 29-year-old birdied three of the last four holes to seize control, with a birdie on the final hole ensuring Schenk finished the day 18 under and ahead of Matthew Wolff.

Schenk holds the outright 54-hole lead – the first of his career in a stroke-play event on Tour – thanks to seven total birdies and just two bogeys at TPC Summerlin.

"It was nice to finish off with a birdie," Schenk said. "Great day. I couldn't have shot many shots lower."

Wolff posted a six-under-par 65, his 11th score in the 60s in 11 career rounds at the Shriners Children's Open.

Andrew Putnam (66), Sam Burns (68) and Chad Ramey (69) are two strokes off the pace heading into Sunday's final round, while Im Sung-jae slipped to 15 under following his third-round 70.

Defending champion Martin Laird recorded a four-under-par 67 to catapult himself 15 positions into a tie for 15th, seven shots behind Schenk.

Brooks Koepka – the four-time major champion – is 12 strokes off the pace following his 72, alongside Viktor Hovland (73), while Masters winner Hideki Matsuyama (71) is five under overall.

Im Sung-jae and Chad Ramey hit rounds of six-under 65 to move into the lead by one shot from last week's Sanderson Farms Championship winner Sam Burns at the halfway point at the Shriners Children's Open.

Day one leader Kang Sung-hoon had a forgettable second round, carding a two-over 73 to slip six shots off the pace at the TPC at Summerlin in Nevada on Friday.

Countryman Im, currently ranked 29th in the world, carded six birdies across his round, including finishing off a birdie on the par-five ninth. Im's bogey-free first two rounds mark the best opening 36-hole score in his PGA Tour career.

American Ramey, who is making only his fifth start in his PGA Tour career, had seven birdies along with a bogey on the first, with the pair level on 14 under after two days.

Burns looms one stroke behind the joint leaders on 13 under, with the 18th-ranked American backing up his opening round of 66, with an eight-under 63.

“What we tried to do is just last week is last week,” Burns told reporters following last week's triumph in Mississippi.

"This week is Shriners and preparing for this week, trying to make sure Monday, Tuesday, Wednesday that we are giving ourselves the best opportunity to play well this week. Obviously, incredible honoured that I won last week and such a fun time, but just trying to kind of leave that there.”

The 25-year-old carded five birdies on his back nine, including a 132-yard wedge which landed within three feet for birdie on the sixth hole.

Burns is joined by Adam Schenk after he carded a six-under 65, with Aaron Wise a stroke behind the duo at 12 under at the halfway mark.

Four-time major winner Brooks Koepka remains in contention after a four-under 67, leaving him seven under.

Ryder Cup debutant Scottie Scheffler and Patrick Reed were among those to miss the cut, while Rickie Fowler along with last week's Sanderson Farms Championship contenders Cameron Burns and Sahith Theegala all missed the cut by a stroke.
