Sepp Straka birdied three of the final five holes to clinch his maiden PGA Tour triumph after overnight leader Daniel Berger crumbled at the Honda Classic on Sunday.

Straka became the first-ever Austrian to win a PGA Tour title while he was the sixth first-time winner on the tour this season.

The 28-year-old Austrian started the final day tied for second in a group of four alongside Shane Lowry, Kurt Kitayama and Chris Kirk who were five strokes behind Berger.

But Straka carded a final-round four-under-66 highlighted by his late flurry in wet conditions at Palm Beach Gardens to win outright at 10-under overall.

"They were pretty tough [conditions]," Straka said after the win. "For a little while the wind let down before the rain started which was nice but on the last hole, that second shot into the green it started pouring rain. I was glad I could hit that one on the green two-putt."

Straka and Lowry went into the 18th hole tied at nine-under, but the Irishman could only make par, while the Austrian's two putt earned him the decisive birdie.

Lowry had led by as much as two strokes down the back nine but Straka surged with a fine approach on the 14th setting up birdie, while he sunk a birdie putt from off the green on the 16th to draw level.

Kitayama finished third at eight-under, with Berger's final-round four-over-74 seeing him slide from a five-stroke lead to three shots off the pace.

The American, who resides nearby to Palm Beach Gardens in Florida, saw him lead evaporate quickly, with a double bogey on the third hole, along with bogeys on the fifth and sixth.

Berger, ranked 20th on the PGA Tour, holed a clutch bunker shot on the seventh hole along with a chip for birdie on the 14th but could not do enough to retrieve his lead.

Florida native Daniel Berger moved five strokes clear ahead of the final day at the Honda Classic, matching the largest 54-hole lead in tournament history on Saturday.

The world number 20 had held a three-shot lead at the halfway mark but extended that with a one-under-69 following back-to-back 65s at Palm Beach Gardens in Florida.

Berger led by as many as six strokes after sticking a brilliant tee shot for birdie on the par-three 15th hole before a bogey on the 18th hole.

The American leads from a group of four players tied on six-under, including Irishman Shane Lowry who carded a round of six-under-67 to move up the leaderboard.

Lowry is tied with Sepp Straka, Chris Kirk and day one leader Kurt Kitayama, with the latter two carding rounds of one-over-71 having been tied for second after the first two days.

“Obviously you want to go out and catch him tomorrow, but I don’t think you can go and catch anyone on this golf course," said Lowry, whose round was the best of the day with only 13 players above even.

“You just need to do your thing and shoot the best score you can and hopefully it will be somewhere near good enough."

Lowry's round included four birdies and a bogey, while he drained a 20-foot putt on the sixth hole to save par.

Canadian Adam Svensson is one stroke back from the quartet at five-under, before a three-shot gap to the next in the field.

Pre-tournament favourites Brooks Koepka and Louis Oosthuizen are both well back, at one-over and two-over overall respectively.

Hometown hero Daniel Berger opened up a three-stroke lead at the halfway mark of the Honda Classic in Florida after carding six birdies on Friday.

Berger, who is ranked 20th in the world, backed up his opening day five-under 65 with a repeat score, highlighted by a 38-foot birdie putt on the par-three seventh hole, to be 10-under at Palm Beach Gardens.

The Florida native leads by three shots from Chris Kirk and first day leader Kurt Kitayama, the latter carding a one-under-69 to slip from the summit.

“Just one of those days when I kept the momentum going,” Berger told reporters. “I hit a lot of quality shots, even though they don't look like they're five feet from the hole, or 10 feet from the hole.

“I know that they're so difficult, that to hit it to 20 feet is a good shot. And that's the challenge for this golf course is the pins are tucked, the greens are firm, wind's up, so you have to be really on point with where you're going to miss.”

Mark Hubbard surged up the leaderboard into a tie for fourth alongside Canadian Adam Svensson with the pair carding rounds of 64 and 65 respectively to be six-under overall.

Pre-tournament favourite Louis Ousthuizen produced a strong round to avoid the cut, after his opening day five-over-75.

The South African is even after two rounds, behind Berger by 10 strokes, but managed six birdies on his back nine to stay in contention after a double bogey on the 11th hole seemed to condemn him.

Four-time major winner Brooks Koepka is among a large group alongside Oosthuizen that are even after two rounds with the American carding a two-over-72.

Padraig Harrington, Brian Harman, Charl Schwartzel and last week's Genesis Invitational winner Joaquin Niemann were among those to miss the cut.

Kurt Kitayama managed four straight birdies on his back nine to claim the lead ahead of Daniel Berger in a group of three after the opening day of the Honda Classic in Florida on Thursday.

The little-known American carded a six-under-round of 64, starting the day with three straight birdies, before his hot run on his back nine at Palm Beach Gardens.

Kitayama has enjoyed a good recent period, making the cut at his past five starts before Thursday's impressive feat as solo leader.

"I think when you're struggling, I think just that self-motivation to find keep getting better and finding a way to figure it out, it's kind of how you've got to keep going," Kitayama told reporters.

The 29-year-old leads by one stroke from Rory Sabbatini, Chris Kirk and hometown hero Berger who are five-under.

World number 20 Berger started his round brilliantly, with three birdies on his first four holes, while he also sunk a 28-foot birdie putt on the ninth hole with no ill-effects from a back problem that has been plaguing him lately.

Slovakian veteran Sabbatini made birdie on the 18th to jump into a share of second, with Kirk having eight birdies and three bogeys in an entertaining round.

Danny Willett, Matthias Schwab, Andrew Kozan, Aaron Rai and Peter Uihlein are all next tied for fifth at three under.

Four-time major winner and current world number 15 Brooks Koepka managed three birdies in his round of two-under-68 to be four shots off the pace.

Last week's Genesis Invitational winner Joaquin Niemann had an even round of 70, despite leading early after four birdies on his front nine, with a double bogey holding him up on the fourth hole.

Pre-tournament favourite Louis Oosthuizen will battle to make the cut after five bogeys on the front nine before a double bogey on the 17th hole left him with a five-over-75.

Billy Horschel leads the way after the opening day of the Farmers Insurance Open in San Diego with world number one Jon Rahm the best of the big names in the field.

Horschel leads by one stroke from Michael Thompson after the 35-year-old American carded a bogey-free nine-under-par 63 on the North Course at Torrey Pines.

World number 23 Thompson also went bogey free on Thursday, birdieing four of his first five holes to jump out of the blocks, before birdies on the 17th and 18th holes rounded out a strong day.

Stephan Jaeger and Kevin Tway are seven-under-par, with Rahm on six-under-par alongside three others players; Rickie Fowler, Doug Ghim and Francesco Molinari.

Rahm's round on the South Course included two bogeys and six birdies but he jumped up the leaderboard with an eagle on the 18th.

Sam Burns, Daniel Berger and Tony Finau are among a group of players tied at five-under while Justin Thomas started with a four-under-par 64 but had five birdies on his front nine before two bogeys in his final five holes.

Tokyo Olympics gold medallist Xander Schauffele and 2020 Masters champion Dustin Johnson are also four under.

A bleach-blonde Brooks Koepka had two bogeys and four birdies to be two under, alongside three-time major winner Jordan Spieth and 2020 US Open champion Bryson DeChambeau.

World number one Jon Rahm made his move on the third day of the Tournament of Champions with a course-record round to join Cameron Smith with a share of the lead in Hawaii.

The Spaniard carded a 12-under-round 61 to move level with Smith, who led by three shots at the halfway mark, on 26 under after three rounds at the Plantation Course at Kapalua Resort.

Rahm's round was an equal course record, with 2017 PGA Championship winner Justin Thomas also carding a 12-under-61 on Saturday to surge up the leaderboard to 17 under.

Last year's US Open champion Rahm shot 11 birdies with one eagle and one bogey in his round, drawing level with the Australian when he sunk a 29-foot putt on the 17th hole.

Smith, who also had a one-shot lead after the opening day, held firm with six birdies on his back nine.

The lead pair are five strokes clear of the next best, with American Daniel Berger slipping off the pace after a third straight round of 66 to be 21 under.

Berger finished his round with five consecutive birdies to keep his faint hopes alive.

Matt Jones, Sungjae Im and Patrick Cantlay are tied at 20 under, ahead of Marc Leishman at 18 under with Thomas and 2021 Masters winner Hideki Matsuyama at 17 under.

Top 10 duo Bryson DeChambeau and Xander Schauffele were unable to make any major inroads on the third day and are further back at 15 under.

The 12 singles pairings for the final round of the Ryder Cup have been announced, with the United States looking to dethrone Europe on Sunday.

Team USA hold a commanding 11-5 lead following Saturday's foursomes and four-ball at Whistling Straits, where the hosts boast the biggest two-day advantage since 1975.

Steve Stricker's USA require just 3.5 points to reclaim the cup from Europe, who will need to produce the biggest ever comeback if they are to claim the required nine points to defend their crown.

"That was an important one," Stricker said after USA split the four afternoon matches. "If they blank us, they're right back in the game. I think getting two points and splitting the session is a good outcome for us."

Xander Schauffele will lead the Americans out to start Sunday's play in Wisconsin, facing struggling European star Rory McIlroy.

McIlroy was dropped for Saturday's foursomes having struggled on Friday – the first time in the four-time major champion's Ryder Cup career that he has missed a session. He returned for the four-ball but fell to another defeat alongside Ian Poulter against Dustin Johnson and Collin Morikawa 4 and 3.

The second matchup pits USA's Patrick Cantlay against Shane Lowry, while Europe captain Padraig Harrington put world number one Jon Rahm down to face Scottie Scheffler.

Bryson DeChambeau and European star Sergio Garcia meet in match four, American Collin Morikawa tackles Viktor Hovland and unbeaten USA veteran Johnson plays Paul Casey.

Elsewhere, Brooks Koepka is set to tee off against Bernd Wiesberger, Poulter and Tony Finau go head-to-head, Justin Thomas will clash with Tyrrell Hatton, Lee Westwood goes up against Harris English, Jordan Spieth faces Tommy Fleetwood and the final matchup is a showdown between Daniel Berger and Matt Fitzpatrick.

United States captain Steve Stricker has selected Jordan Spieth and Xander Schauffele among his wildcard picks for the Ryder Cup, but there is no place for Patrick Reed on the 12-player roster.

Spieth will appear at the biennial competition for a fourth time in a row, while Schauffele is set to make his debut against Europe in next month's tournament at Whistling Straits after recently winning Olympic gold.

Schauffele was one of three rookies chosen by Stricker on Wednesday along with Daniel Berger, Harris English and Scottie Scheffler, with Tony Finau – part of the USA side that lost in Paris three years ago – completing the captain's picks.

Speaking at a news conference to announce his final selection, Stricker said: "All six of these guys have been playing some really good golf for a long period of time. 

"It's more about a body of work. They have all played great throughout this year and very well deserving of these picks."

The top-six qualifiers – Collin Morikawa, Dustin Johnson, Bryson DeChambeau, Brooks Koepka, Justin Thomas and Patrick Cantlay – had already locked in spots for the USA, who are seeking to regain the trophy after that 17.5-10.5 loss in 2018.

Reed is the most notable name overlooked by Stricker, the 31-year-old having featured in every American team since 2014. 

He made his return from a month-long absence at last week's Tour Championship after being hospitalised with pneumonia in both lungs.

Asked to explain his decision to overlook Reed, who top-scored for USA in their 2016 victory at Hazeltine, Stricker said: "That was a very, very difficult call. I lost sleep over that one. 

"He's a tremendous competitor, he brings a lot of match play golf and his record at the Ryder Cup is pretty darn good.

"I think it was the uncertainty of his health and the lack of play that led to our decision down the stretch."

Team Europe captain Padraig Harrington will announce his final three picks on Sunday.
