Cameron Tringale and Andrew Landry earned a share of the one-stroke lead after the third round at the John Deere Classic.

Tringale carded a six-under-par 65 and fellow American Landry posted a penultimate-round 67 to rise to the top of the leaderboard on Saturday.

Seeking his maiden PGA Tour title, Tringale had seven birdies and a bogey as he climbed three positions at TPC Deere Run.

Landry – winner of last year's Texas Open – is also 16 under through 54 holes following a round which included six birdies and a pair of bogeys on the back nine.

Bill Haas, who has not won an event on Tour since January 2015, is one shot back following his seven-under-par 64, alongside Adam Schenk (66).

Four golfers are tied for fifth at 14 under, including Nick Watney (64) – who continues to have an under-the-radar solid season.

Meanwhile, Matthew Wolff continues to impress after his third-round 67 to be tied for 33rd.

Wolff won the 3M Open in just his third professional start last week, having won the NCAA individual title with Oklahoma State six weeks earlier.

"I would not be surprised if he was on that Presidents Cup team that went to Australia," Charles Howell III said on Wolff. "He would be a guy to look at if I was Tiger [Woods]."

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

"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.
