Brooks Koepka edged a battle of two heavyweights at the WGC-Dell Technologies Match Play, needing a 19th hole to beat world number one Jon Rahm.

The two were paired in the pick of a round of 16 that delivered its fair share of thrills and spills early on Saturday.

Koepka was 2 up twice on the back nine, only to be reeled in by Rahm at the 16th and 17th, meaning an additional hole was required.

A birdie from Koepka was enough as they replayed the 10th, setting up another intriguing quarter-final clash with Dustin Johnson.

For a time, it appeared Johnson would be joining Rahm in making an early exit, as 49-year-old opponent Richard Bland was 2 up through five holes.

However, Bland double-bogeyed the sixth as he lost four of the next five holes, allowing Johnson to canter home 3 and 2.

The other standout match-up saw a replay of last year's final. Billy Horschel won the 2021 title, but he was beaten this time by Scottie Scheffler, who finished 1 up.

Scheffler's next task is against Seamus Power, who this time last year was finishing in a tie for 54th at the Corales Puntacana Resort and Club Championship, leaving him ranked 463rd in the world.

On Saturday, Power routed Tyrrell Hatton 4 and 3 – albeit not the biggest win, as Abraham Ancer dominated Collin Morikawa 7 and 6 and will face Corey Conners, a 5 and 3 winner.

In the final section of the draw, Will Zalatoris required 22 holes to get the better of Kevin Na, with Kevin Kisner up next.

Jon Rahm and Brooks Koepka will face off in the last-16 at the WGC-Dell Technologies Match Play, after they secured progression from the group stage on Friday.

Top-seed Rahm was defeated 3 and 2 by Patrick Reed, who was already eliminated, while Koepka needed a birdie on the last hole to beat Shane Lowry and go 3-0 in group play.

Scottie Scheffler and Billy Horschel set up a replay of last year's Match Play final, after they won their respective groups.

Following a loss to Ian Poulter in the second round of play, Scheffler recovered strongly to defeat Matt Fitzpatrick 5 and 4, before then taking the playoff out with both at 2-1. Horschel tied with Thomas Pieters after 18 holes to guarantee his place.

Dustin Johnson went 3-0 in the group, after he was able to see off a closing two birdies from Max Homa and win 1-up.

He will face 49-year-old Richard Bland, who went 2 and 1 over countryman Lee Westwood to finish Group 9 with two wins and a tie.

Seamus Power lost his final game to Keith Mitchell in Group 4, but still managed to top the group and secure a last-16 tie against Tyrell Hatton. In the process, the 35-year-old Irishman has also secured his first Masters appearance.

Collin Morikawa secured passage to the knockout phase, defeating Jason Kokrak 1-up, while Adam Scott, Abraham Ancer, Kevin Kisner also managed to make the last-16.

Meanwhile at the Corales Puntacana Championship, Ben Martin leads Alex Smalley by two strokes after 36 holes, shooting another six-under 66 for the day.

Several of the biggest names on the PGA Tour continued strong starts at the WGC-Dell Technologies Match Play on Thursday, but Bryson DeChambeau was not among them.

Jon Rahm, Dustin Johnson and Brooks Koepka have all enjoyed 2-0-0 starts in Austin as they aim to top their four-man groups and reach the weekend.

Yet DeChambeau had only been able to tie with 49-year-old Richard Bland – bidding to become the oldest professional to qualify for the Masters – on Wednesday, with even that result requiring a little luck.

Up against Lee Westwood on Thursday, DeChambeau knew he must improve but did not. Westwood finished 1 up to leave DeChambeau bottom of Group 9 with just half a point.

DeChambeau at least has the excuse he is struggling with a wrist injury; world number four Patrick Cantlay will do well to explain away his below-par performances.

Cantlay lost his narrow lead over Keith Mitchell late on Wednesday and was well off the pace when play resumed in round two, beaten 5 and 4 by Seamus Power.

That result tied the biggest of Thursday, with Rahm and Justin Thomas also 5 and 4 winners against Cameron Young and Marc Leishman respectively.

Nothing quite compared to Maverick McNealy's sensational 8 and 6 defeat of Joaquin Niemann from the previous day – and McNealy could only tie with Kevin Na on Thursday, despite twice being 3 up.

Elsewhere, at the Corales Puntacana Resort and Club Championship, the tournament got under way with Ben Martin moving to the top of the leaderboard with a six-under 66, enough for a one-stroke lead.

Scottie Scheffler backed up last month's Phoenix Open triumph by taking out the Arnold Palmer Invitational by one stroke after a final round of 72 at Bay Hill on Sunday.

Scheffler carded an even-par round with three birdies and three bogeys to finish five under and one shot ahead of Viktor Hovland, Billy Horschel and Tyrrell Hatton – who stormed 10 places up the leaderboard with a final-day 69 to earn a tie of second.

The 25-year-old Scheffler made his move on the third day, with a five-under 68 launching him into contention. American Scheffler will now move up to fifth on the official world rankings.

Joint overnight leaders Horschel and Talor Gooch lost their grip on top spot, with the former making three bogeys and a double bogey on his final-day front nine before finishing with a three-over 75.

Gooch ended up two further strokes back with a five-over 77 after four bogeys and two double bogeys on his front nine.

Norwegian world number four Hovland loomed as the likely player to capitalise on their misfortune, as he assumed the lead.

But five bogeys in Hovland's closing 11 holes left the door open for Scheffler, who held his nerve, notably making an excellent long putt to save par on the 15th hole.

"It feels great, especially to win on such a difficult golf course and the way it finished," Scheffler told Sky Sports.

"I didn't play my best stuff, I just kept grinding and made some key putts down the stretch, and it was really just a fight all day."

First-round leader Rory McIlroy never threatened on Sunday, with a four-over-76 meaning he finished back at one over after 72 holes.

World number one Jon Rahm was one stroke behind the Northern Irishman after a final-round 74.

Norwegian world number four Viktor Hovland surrendered his lead at the Arnold Palmer Invitational with two bogeys to finish the third day at Bay Hill on Saturday.

Hovland, who was the leader at halfway, carded a three-over 75 with six bogeys, saving face with a hole-out eagle from the bunker on the sixth and birdie on the eighth.

The Norwegian had retained his lead until bogeys on 17 and 18 allowed American pair Billy Horschel and Talor Gooch to claim a share of the lead.

Horschel and Gooch are seven-under after 54 holes, with Hovland one stroke back, followed by Scottie Scheffler at five-under after he carded a joint round-high four-under-68.

"I was really in a good rhythm until some bad shots on the back nine," Hovland told reporters.

On his hole-out eagle, he added: "That was awesome. Obviously, not the greatest start to the day. Even the pars that I made on the next few holes was really scrappy. Hit some really bad shots.

"Then obviously walking up to the greenside bunker on that hole was hard on the downslope and no green to work it. I thought I was in no man's land, just try to chunk it out there and give myself a putt at it. It came out really soft and landed in the first cut and just died and went in."

Horschel carded a one-under-71 to claim the joint lead, with three bogeys and four birdies, including closing out with an important birdie putt.

Gooch had an even round for 72, bogeying the 18th to settle for a share of the lead after he had birdied both the 15th – with a 33-foot putt - and 16th.

Scheffler surged up 16 spots and into contention with a round that included three birdies and an eagle on his back nine. The American rolled in a 21-footer for eagle on the 16th.

Max Homa, playing alongside Scheffler, landed a rare ace on the 14th hole although he is off the pace with an even card overall in a group featuring top-ranked Jon Rahm.

Gary Woodland is behind Scheffler at four-under, with Rory McIlroy among a group of three at three-under ahead of the final day.

Viktor Hovland holds a two-shot lead at the half-way point of the Arnold Palmer Invitational after Rory McIlroy endured a disappointing finish.

Overnight leader McIlroy was not as sharp as he was on the opening day at Bay Hill but still looked in with a chance of retaining his status as pacesetter for much of the round.

That was until the 15th, when he needed three putts from 30 feet. He then missed a birdie opportunity on 16 and failed to save par from eight feet on 17.

The Northern Irishman ultimately finished at level par for the day with 72 – Hovland, who started on the 10th, carded 66, giving him the round of the day and the lead.

His score would have been even better had he not bogeyed the 13th, however he responded admirably to that set-back with three birdies in his next four holes.

Hovland added two more on the fourth and sixth to ultimately set the clubhouse lead as he moved to nine under for the tournament – McIlroy failed to rise to his challenge.

Joining McIlroy two shots back on seven under in a tie for second are Talor Gooch and Tyrrell Hatton, the latter of whom felt his four-under 68 was "pretty flattering".

Similarly, Hovland is not getting carried away with his position in the standings, particularly considering he was only two shots off the lead heading in the weekend last year and went on to finish 15 off the pace.

"I kind of try to forget the weekend here last year," Hovland told the PGA Tour. "I played really well the first few days, very similar to how I played so far this year.

"The course just gets harder and harder every single day, and it started blowing. A few too many bad swings and I ended up in bad spots and just didn't really take my medicine."

As for McIlroy, the four-time major champion was taken aback by how quickly conditions on the course changed from Thursday, adamant he will be better prepared on day three.

"Those are the sort of greens you expect to see late on a Sunday, not late on a Friday," McIlroy added. "It's going to be interesting to see where they go from here, but it's going to be a good test over the weekend.

"I'm glad I got 18 holes in those conditions because the course definitely changed a lot from when I played it yesterday morning to this afternoon. I'll be a little more prepared for it [on Saturday]."

Billy Horschel is one shot further back on six under, and then there's a three-shot gap to a group of seven – world number one Jon Rahm is at two under.

Patrick Reed, Henrik Stenson and Justin Rose were among those to miss the cut, which was set at three over par.

Four-time major winner Rory McIlroy leads by two strokes after a first-round 65 that included an eagle at the Arnold Palmer Invitational at Bay Hill in Florida on Thursday.

McIlroy made six birdies and an eagle on the 16th hole to card a seven-under-65 with a bogey on the 11th the only blemish on his scorecard.

The Northern Irishman, who made 11 of 14 fairways, leads by two strokes from American trio Beau Hossler, JJ Spaun and Billy Horschel, with a group of six players one further shot back including Sungjae Im and Will Zalatoris.

“This is my fourth start of the calendar year. I’ve had one really good chance to win and probably one other half chance," McIlroy told reporters after day one.

"I feel like I’m playing well enough to have chances to win golf tournaments, but all you can ask of yourself is to keep putting yourself in those positions on Sundays and then you see where your game really is.

“Hopefully, this is another week where I put myself in a position where I can really see where my game is when the pressure is on.”

McIlroy's day was highlighted by his 41-foot putt for eagle on the par-five 16th hole.

"I played the par-fives particularly well, and that was the bulk of the score," said McIlroy who won at Bay Hill in 2018.

"I've said this all along: You can play within yourself here and still shoot a good score, I feel, if you're just disciplined and pick off the birdies where you're supposed to."

McIlroy is one of four players from the PGA Tour's top six, with world number one Jon Rahm struggling with an even round on the opening day - including falling short on a gimme putt - to be seven shots off the pace.

Viktor Hovland carded a three-under-round of 69, while Scottie Scheffler is two under after the first day.

Rory McIlroy believes the identity of those rejecting the Super Golf League "has to tell you something", as both he and Jon Rahm remain committed to the PGA Tour.

A number of high-profile players are said to have been targeted by organisers of the lucrative Saudi-backed breakaway, including Dustin Johnson, Bryson DeChambeau and Phil Mickelson.

But the most prominent names to have discussed the league publicly – including McIlroy, Rahm and Collin Morikawa – have instead pledged their allegiance to the PGA Tour.

McIlroy referred to the rival series as the "not-so-Super League" on Wednesday, declaring himself "so sick" of the subject.

He added: "You look at the people who have already said no. You've got the top players in the world who are saying no, so that has to tell you something."

World number one Rahm also appears fed up with fielding questions on the Super Golf League but clarified his stance – speaking, like McIlroy, ahead of the Genesis Invitational.

"This is my official one and only time I'll talk about this, where I am officially declaring my fealty to the PGA Tour," Rahm said.

"I'm a PAC [Player Advisory Council] member, and I have a lot of belief in [PGA Tour commissioner] Jay Monahan and the product that they're going to give us in the future.

"There has been a lot of talk and speculation about the Saudi league. It's just not something I believe is the best for me and my future in golf, and I think the best legacy I can accomplish will be with the PGA Tour."

Jon Rahm has won the Seve Ballesteros award for the second time in three years after being voted player of the year by his fellow DP World Tour members.

Rahm won the U.S. Open by one shot at Torrey Pines in June, his first major victory, and also finished in the top 10 in the other three majors in 2021.

He tied for fifth at The Masters and eighth at the US PGA Championship, before finishing level with Louis Oosthuizen in third at The Open at Royal St George's in July.

The world number one also top scored for the defeated European team at the Ryder Cup, winning 3.5 points in his five matches including remaining undefeated alongside fellow Spaniard Sergio Garcia despite the United States winning 19.5-9.5 at Whistling Straits in September.

Rahm was pleased to win the award for a second time, especially given its famous title.

"Winning anything with Seve's name on it is a huge honour for me, as is the fact that this is voted for by the players of the DP World Tour," the 27-year-old Spaniard told the DP World Tour's website.

"It is very unique to be recognised by your peers like this. It is a true honour to be able to win this award for a second time and hopefully I can continue to make the DP World Tour proud."

DP World Tour CEO Keith Pelley added: "In the first year of this being the Tour's combined Player of the Year award named in honour of one Spanish great, it is fitting the winner is another incredible Spaniard who is creating his own remarkable legacy on the global stage.

"Jon's form throughout 2021 was simply outstanding and his victory at the U.S. Open, in front of his family, was undoubtedly a highlight that will live long in the memory.

"That cemented his place among the pantheon of Europe's all-time leading players and his contribution in the colours of Europe at the Ryder Cup also demonstrated what an extraordinary competitor he is."

Brooks Koepka made a strong start to the Phoenix Open as he heads into day two in a tie for third at five under par, with the four-time major winner looking to put an "embarrassing" fall from grace behind him.

Koepka has not won a tournament since succeeding in Phoenix a little under a year ago – while he impressed at the PGA Championship in May, finishing joint-second, Koepka is not happy with how the past 12 months or so have gone.

He teed off in Arizona ranked 20th in the world, something of a far cry from spending 47 weeks at number one across 2018 and 2019 – three of his four major wins came in those years.

Koepka, rarely one to mince his words, feels ashamed of his slide, even if he puts it partly down to injury.

"That's embarrassing to be 20th, I feel like," he said after his first round on Thursday.

"A lot of it has to do with injury, man. I've been hurt, on the sidelines. Not playing, playing through injury, you can't compete with guys out here.

"It's nice to be somewhat healthy and get out here, and I mean, I'm not too worried about it [the ranking], it will bounce back up."

Indeed, there was nothing embarrassing about his performance at TPC Scottsdale on day one, his six birdies – offset by a single bogey – putting him right near the top of the leaderboard.

Nevertheless, he still has a plenty of work to do.

Lee Kyoung-hoon is one shot better off thanks to a glorious showing after the turn, playing the front nine five under par after starting on the ninth hole.

But leading the way is a surprise contender: 24-year-old Sahith Theegala, who is competing as a sponsor's exemption.

Theegala has a one-shot lead over Lee, though he had to finish his round while putting on his 17th hole of the day as play was suspended due to bad light.

Additionally, his next shot when he resumes in the morning will be a 16-foot putt for par, so his lead may not last for long.

A host of familiar names are not too far behind those leading the way, with Xander Schauffele, Louis Oosthuizen, Patrick Cantlay, Jon Rahm and Bubba Watson among a large group on four under.

Jordan Spieth is three shots further back.

Luke List has had a long wait for his first PGA Tour win and that was extended after a two-hour wait before triumphing in a playoff over Will Zalatoris at the Farmers Insurance Open on Saturday.

The 37-year-old American, enjoyed an excellent final round six-under-66, highlighted by four consecutive birdies from the third to the sixth holes, to storm up the leaderboard at Torrey Pines.

But List, in his 206th career start, waited almost two hours after entering the clubhouse as the overnight leaders completed their rounds before facing Zalatoris, who also finished 15-under overall, in an 18th hole playoff.

In fading light, the pair both landed their tee shots within inches of each other in a bunker, with List's third shot placed close to the hole, enabling him to tap in to card a birdie.

Zalatoris pushed his longer birdie putt, which was near-identical to his 18th hole putt for victory that he missed, wide left again to settle the playoff in List's favour.

California-born 25-year-old Zalatoris may have clinched victory on the 18th as List patiently waited and practiced elsewhere, but was agonizingly short and slightly wide after a late fade on his putt.

He carded a final round one-under-71, grouped alongside Jason Day and Aaron Rai, with world number one Jon Rahm also making a late charge.

Day shot into a share of the lead after landing an eagle on the 14th hole but had to settle for joint third alongside Rahm and Cameron Tringale at 14-under-par overall.

The Australian, who had not won a PGA Tour title in 1,364 days, finished with back-to-back bogeys to slip from contention.

Rahm rolled in a clutch 26-foot putt to birdie the 17th to be one shot off the pace but only managed par on the last hole.

Joaquin Niemann, Justin Rose, Pat Perez, Sungjae Im and Rai were next, finishing 13-under overall.

Adam Schenk carded a 10-under-par to surge into a share of the lead alongside top-ranked Jon Rahm and Justin Thomas at the halfway mark of the Farmers Insurance Open on Thursday.

Schenk, who is ranked 54th and has never won a PGA Tour title, carded a career-best PGA Tour round of 62, which included making 10 birdies and hitting four of 14 fairways.

The American, who turned 30 on Wednesday, made eight consecutive birdies was within one shot of equaling the course record, with his 15-feet putt on the 18th hole lipping out.

Reigning US Open winner Rahm, who opened the tournament with a six-under-par 66, backed up with a seven-under-round on the second day on the North Course at Torrey Pines.

World number six Thomas is locked with Schenk and Rahm at 13-under overall after his nine-under round.

The trio lead from Cameron Tringale at 12-under, with Peter Malnati next with 11-under.

Opening day leader Billy Horschel slipped down the leaderboard after a one-over round to be eight-under overall.

Will Zalatoris, who started and finished the second day with eagles, is among a group of six at seven-under including Dustin Johnson.

Phil Mickelson, Bryson DeChambeau, Jordan Spieth, Rickie Fowler, Tony Finau and Brooks Koepka were among the notable players to miss the cut.

Spieth's four-over card ended his run holding the longest active made-cut streak (20) on the PGA Tour.

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.

First day joint leader Lee Hodges returned to the summit alongside Paul Barjon after carding an eight-under 64 while world number four Patrick Cantlay slipped down the leaderboard on the third day at the American Express.

Event debutant Hodges responded after his second day 72 with a fine round that included six birdies on the front nine on the stadium course at La Quinta in California on Saturday.

Hodges is 18-under overall, sharing the lead with France's Barjon who carded a seven-under 65 on the stadium course to also soar up the leaderboard.

Cantlay, who had shared the lead with Hodges after the first day and was the outright leader after the second, carded four bogeys in his even-round 72 which saw him slide to 14-under overall.

Tom Hoge remains poised one shot off the leaders at 17-under overall, with five birdies and one bogey in his round of 68.

Ireland's Seamus Power is one stroke behind Hoge, with Harry Higgs, Hudson Swafford, Lanto Griffin, Cameron Young, Harold Varner III and Francesco Molinari all next best 15 under.

World number one Jon Rahm is not far behind, having carded a five-under 67 to be 13-under overall, while veteran Phil Mickelson missed the cut.

Patrick Cantlay secured a one-shot lead on 14-under par ahead of Tom Hoge on the second day of the American Express in California on Friday.

The world number four followed up his impressive round of 62 on the opening day with a four-under 68 to hold the outright lead at the end of day two, with Hoge following up a first day 65 with another respectable round of 66 to sit on 13-under.

The best round of the day came from Will Zalatoris, who shot an 11-under 61 to move up 93 places to joint-third after having hit just 10 greens in his opening round 71.

The 25-year-old American managed 12 birdies, including each of his last seven holes to climb up the leaderboard, and now sits level on 12-under with fellow countrymen Lanto Griffin, Greyson Sigg, Cameron Young and Joseph Bramlett.

His drive on the final hole actually ended in the rough on the adjacent first hole, but he was still able to make birdie.

“I think today I just gave myself chances," Zalatoris said after his round. "I hit a lot close and made a couple 20, 30 footers to keep the round going and obviously... making birdie on nine from the wrong fairway is kind of the icing on the cake."

Sam Ryder, Roger Sloan, Zach Johnson and Paul Barjon ended their second rounds tied for eighth on 11-under. 

Meanwhile, Lee Hodges, who held the lead with Cantlay at the start of day two, could only muster an even-round of 72 and now finds himself tied for twelfth with 11 other competitors.

Among them is Sahith Theegala, who shot an eagle and eight birdies as part of a round of 62 to climb 98 places to inexplicably sit alongside the previous day's overnight joint-leader.

World number one Jon Rahm was unable to build on his steady first round of 66 as he hit five birdies and three bogeys during his 70 to sit tied for 32nd on eight-under.
