Kevin Na cruised to a four-stroke victory at the Charles Schwab Challenge on Sunday.

Na entered the final round in the lead and the 35-year-old never looked back following a four-under-par 66 in Fort Worth, Texas.

He had six birdies – four of which were on the front nine – and a pair of bogeys en route to his third PGA Tour title.

Na finished 13 under overall at Colonial Golf Course, ahead of fellow American Tony Finau.

"It feels great," Na said after his round. "Standing on the first tee, I looked at that wall [of winners at Colonial] and I imagined my name on it, and sure enough it's going to be there.

"Every year I come here I know I have a chance to win, and I knew before my career was over I was definitely going to win out here, if not multiple times. It's nice to get one, and who knows, maybe I'll win a couple more times before my career is over here."

Finau, who was the 18-hole leader, remained in contention and ultimately finished runner-up following his final-round 68.

He used a birdie on the par-four 18th hole to break out of a tie for second place.

It was his fifth second-place finish since the start of the 2017-18 season — the most of any player on Tour.

Andrew Putnam (66) and C.T. Pan (69) were a shot further back and tied for third, while Jonas Blixt (68) rounded out the top five at seven under.

Rory Sabbatini (67) and Ryan Palmer (69) were locked into a tie for sixth place at six under and Jordan Spieth joined Tyrrell Hatton and Mackenzie Hughes, among others, in a tie for eighth.

Former world number one Spieth had three bogeys and a birdie for a two-over-par 72 as he finished eight strokes off the pace.

Kevin Na built on an impressive second round to take the lead at the Charles Schwab Challenge on Saturday.

The two-time winner on the PGA Tour carded a one-under 69 in the third round to hold a two-stroke lead over the rest of the field.

Na, who carded the best round (62) of the tournament on Friday, played steady golf at Colonial Country Club in Fort Worth, Texas.

Na finished the day with three birdies, including two to open the round on the first and second holes. His only mistake came on the par-five 11th, where he had his first double bogey of the week.

He is nine under for the tournament.

"Over the years I've had some good rounds [at Colonial] and it's a golf course you don't have to overpower. You have to keep it in play," Na said, via Golfweek.com.

"From fairway in I'm a pretty good player, so I think it plays right into my game."

Right behind him is a star-studded tie for second place at seven under, including Jordan Spieth, Tony Finau and Jim Furyk. C.T. Pan and Mackenzie Hughes join them.

Spieth's game, including his putting, has been superb this weekend as he is chasing his first win since the 2017 Open Championship.

It is a good sign for Spieth, who had failed to finish inside the top 20 this year until ending up tied for third at last week's US PGA Championship.

Spieth also opened his round with birdies after a 29-foot putt on the par-five first hole and another 20-foot putt on the par-four second.

Charley Hoffman and Austin Cook are locked in a tie for seventh place at six under while Ryan Palmer, Nick Watney and Jonas Blixt – who was leading the field after 36 holes – are tied for ninth at five under heading into Sunday's final round.

Jonas Blixt took control of the Charles Schwab Challenge after claiming a one-stroke lead at the halfway stage on Friday.

Swedish golfer Blitx carded a six-under-par 64 to sit atop the leaderboard after round two at Colonial Country Club in Fort Worth, Texas. 

Blixt – who is chasing his fourth PGA Tour win and first since claiming the 2017 Zurich Classic of New Orleans – enjoyed a bogey-free round with four birdies and a hole-out for eagle on the par-four 17th.

The impressive hole-out put Blixt one stroke ahead of Kevin Na and Tony Finau, who are tied for second position, at nine under.

Finau had the 18-hole lead but still remains in contention despite a bogey staining his scorecard early in the round. He played steady golf the rest of the way to finish two-under 68.

Na, who has had success at the Colonial Golf Course in Fort Worth, Texas, shot a 62 for the best round of the day.

Rory Sabbatini has sole possession of fourth place at six under, a stroke ahead of former world number one Jordan Spieth.

Spieth – who was tied for third at the US PGA Championship – posted a 70 to be level alongside Nick Watney (68), Jim Furyk (66), C.T. Pan (67) and Jason Dufner (68).

The three-time major champion had another good day putting. Spieth had a career first when he made three putts from outside 40 feet in a single tournament.

Defending champion Justin Rose was able to make the cut after his three-under-par 67 left him one over after 36 holes.

While Rose qualified for the weekend, the likes of Rickie Fowler, Jon Rahm, Bryson DeChambeau, Xander Schauffele and Zach Johnson missed the cut.
