Kalle Samooja carded a magnificent final round of 64 to claim his maiden DP World Tour title in the European Open at Green Eagle in Winsen.

The Finn saw off Dutchman Wil Besseling by two strokes after posting an astonishing eight under on Sunday to seize victory from behind.

The 34-year-old had looked to be comfortably out of the running at the end of the third day, after a score of 74 left him two over following par scores on Thursday and Friday.

But Samooja was able to take advantage of a frustrating day for previous leader Victor Perez, who came back down to earth after a sublime hole-in-one on Saturday.

Having made par across the first five holes, a run of five birdies in the next seven helped haul the Samooja into contention as his rivals faded.

Back-to-back birdies on the 16th and 17th helped seal the deal, and Samooja was left to celebrate his first tour triumph after an unlikely surge.

Sebert Walker Jr. dropped six shots by the end of the third day of the Jamaica Golf Association's National Senior Trials at the Half Moon Golf Course in St. James but still enjoys a sizeable buffer over the rest of the field.

After months of claim, counter-claim and controversy, the LIV Golf Invitational Series turns its focus to actual golf on Thursday.

The first event of a series previously known as the 'Super Golf League' gets under way at the Centurion Club, near London, next week.

A lucrative breakaway from the PGA Tour and DP World Tour, there will be plenty of interest in how LIV Golf fares – even if it is a largely unpopular venture.

Regardless of its wider reputation, though, the money of Saudi Arabia's Public Investment Fund (PIF) has still attracted some of the sport's best players.

So, what is the deal with LIV Golf? How does it work? Who will be playing? And why has it caused such uproar?

Stats Perform attempts to answer the myriad questions around this contentious competition.

What is LIV Golf?

A Saudi-backed rival to the PGA Tour has been rumoured for years, taking on various names before finally launching as the LIV Golf Invitational Series.

Greg Norman, a two-time Open champion and LIV Golf's CEO, has described this as the arrival of "free agency" in golf, with leading players skipping PGA Tour events to play in the new series.

That is exactly what the PGA Tour sought to avoid when it vowed to ban any players who joined a rival league, although that promise has not yet come to pass.

"Our mission is to modernise and supercharge the game of professional golf through expanded opportunities for both players and fans alike," reads LIV Golf's website, adding its aim to provide "a cutting-edge entertainment product".

That does not only mean a new series and new events, but also a new format...

How does it work?

Gone is the long-established structure of 72 holes across four days with the field cut after two rounds.

Regular season LIV Golf events will last only 54 holes and three days, with no cuts, meaning – organisers point out – there is no danger of eye-catching names being absent for the end of the tournament.

There are also shotgun starts, "ensuring a faster and more exciting pace of play", and smaller fields with only 48 players.

This may all be unfamiliar, but it is at least straightforward. The other changes are a little more complex.

Players will be pursuing individual glory, as at any other golf tournament, but there are also team prizes on offer, with each field broken up into 12 four-man teams.

At every event, there will be an individual winner – the traditional victor with the lowest 54-hole score – and a triumphant team, whose score will be calculated using their best two scores over the first two rounds and their best three from the third.

The first seven events of the season – four in the United States and one each in England, Thailand and Saudi Arabia – will provide a seasonal individual champion, while the year's most successful team are then identified at a further match-play knock-out tournament.

Who's playing?

With a number of big names publicly opposing the breakaway, Rory McIlroy referred to the then Super Golf League as the "not-so-Super League" back in February.

But LIV Golf claims to have received 170 applications and has been able to recruit some superstar talent – namely Dustin Johnson, whose agent said it was "in his and his family's best interest to pursue it".

"Dustin has never had an issue with the PGA Tour and is grateful for all it has given him," David Winkle added. "But in the end, [he] felt this was too compelling to pass up."

It remains to be seen how regularly Johnson will appear in the series, given the field is set to change for every event. He is on board for the London opener, though, alongside Sergio Garcia.

With the four-man teams – who will have their own logos, colours and names – to be tweaked at each tournament, captains will draft players to join them. Unlike at the Ryder Cup, these captains are also active players.

The opening London draft is set for Tuesday, but Phil Mickelson – the most notable and controversial potential LIV Golf star – will not be involved.

Given his previous interest, Mickelson is surely likely to appear at some stage, but he has not played for several months since his comments in relation to the tournament and its funding prompted an apology.

Why's it so controversial?

Any rebel league that threatened the PGA Tour was unlikely to be globally popular, but Saudi Arabia's influence has contributed significantly to the backlash.

The country's human rights record is of major concern, along with its role in the war in Yemen, so ventures such as these – and the acquisition of Premier League club Newcastle United – by its PIF are widely cited as examples of sportswashing.

Norman has suggested Saudi Arabia is "making a cultural change".

While he described the murder of journalist Jamal Khashoggi at the Saudi consulate in Istanbul in 2018 as "reprehensible", the LIV Golf chief added: "Look, we've all made mistakes, and you just want to learn from those mistakes and how you can correct them going forward."

Norman was speaking last month, by which point Mickelson's own discussion of Khashoggi's death had done a great deal of harm to the league's reputation.

The six-time major champion acknowledged Saudi Arabia's "horrible record on human rights" but added he was willing to commit to LIV Golf as it was "a once-in-a-lifetime opportunity to reshape how the PGA Tour operates".

Mickelson made those comments in November last year, although they were reported earlier this year just as the series sought to launch.

Norman said the saga "definitely created negative momentum against us" and revealed "everybody got the jitters", causing some players to back out.

Billy Horschel shot a blistering seven-under 65 on Saturday to secure a five-stroke lead heading into the final round of the Memorial Tournament.

Horschel shot another bogey-free round on Saturday to extend his streak to 44 consecutive holes, with his last coming on the 10th hole in the first round.

One year after Jon Rahm built a six-stroke lead coming into the Sunday at the Memorial, before having to withdraw due to a positive Covid-19 test, Horschel will have a chance to see off the field with a healthy buffer.

After chipping in for birdie on the opening hole, Horschel played incisively from there as the course firmed, zeroing in on the pin and not leaving himself with much work on the greens at Muirfield Village.

The 35-year-old will be going for his seventh tournament win on the PGA Tour, with his last victory coming at the 2021 WGC Match Play, defeating Scottie Scheffler in the final.

World number three Cameron Smith commenced with a one-stroke lead on Saturday but started slowly with bogeys from the bunker on the opening two holes.

He recovered from another bogey to open the back nine to finish on even par for the round, remaining on eight-under for the tournament.

The Australian is tied for second with Aaron Wise, who steadied after a fast start on the front nine to score a three-under 68 on Saturday.

A three-way tie for third between Daniel Berger, Francesco Molinari and Jhonattan Vegas sits a further stroke back.

Meanwhile, defending champion Patrick Cantlay sits on six-under along with another four players.

Minjee Lee is threatening to run away with the U.S. Women's Open, taking a three-stroke lead heading into the final round on Saturday.

Lee fired a four-under 67 to move to 13-under after 54 holes, breaking the U.S. Women's Open 54-hole record of 201 set in 1999 by Juli Inkster by a single stroke.

The world number four started the third round slowly, scoring a bogey on the fifth hole to fall two shots behind Mina Harigae.

Lee responded quickly with a birdie on the sixth, before breaking the round open with four consecutive birdies between nine and 12.

Playing alongside Lee in the final group, Harigae faltered meanwhile, firing consecutive bogeys on the 11th and 12th hole respectively.

The past three third-round U.S. Women's Open leaders at Pine Needle have all gone on to win the tournament, including Lee's fellow Australian Karrie Webb in 2001.

Kevin Na has announced his resignation from the PGA Tour ahead of his participation in the LIV Golf Invitational Series.

Na, who is a five-time winner on the PGA Tour, posted on social media on Saturday his reasons for resigning, suggesting it was due to the Tour's attitude towards players competing in rival events.

A Saudi-backed rival to the PGA Tour had been rumoured for years before the launching of LIV Golf was recently confirmed.

Greg Norman, a two-time Open champion and LIV Golf's CEO, described it as the arrival of "free agency" in golf, with leading players skipping PGA Tour events to play in the new series.

However, the Tour has previously suggested it would ban players who joined the breakaway.

Na, who is the world number 33, was among 13 players from the PGA Tour listed as part of the field for the first LIV Golf event in London next week, along with the likes of Dustin Johnson, Lee Westwood and Sergio Garcia.

Na posted on Twitter: "For 19 years I have played on the PGA Tour and loved every minute of it. I appreciate the platform the Tour has provided me to play the game I love and for the opportunities that come with it.

"Recent developments in the professional golf world have given me a chance to reconsider my options. I would like the freedom to play wherever I want and exercising my right as a free agent gives me that opportunity.

"However, to remain a PGA Tour player, I must give up my right to make these choices about my career. If I exercise my right to choose where and when I play golf, then I cannot remain a PGA Tour player without facing disciplinary proceedings and legal action from the PGA Tour.

"I am sad to share that I have chosen to resign from the PGA Tour. This has not been an easy decision and not one taken lightly. I hope the current policies change and I'll be able to play on the PGA Tour again.

"I am thrilled to begin the next chapter in my career, starting next week at the inaugural LIV Invitational Series event in London. I hope you'll continue to support me."

The 38-year-old's last Tour win came in January 2021 at the Sony Open in Hawaii.

Australian Minjee Lee and American Mina Harigae are tied for the lead at nine under after two rounds of the U.S. Women's Open played at Pine Needles.

Harigae was tied for the lead after Thursday's first round, and followed it up her 64 with a solid 69, while Lee posted a 67 on Thursday and then followed it with Friday's second-best round of the day, shooting a 66.

The actual round of the day went to South Korea's Choi Hye-jin, who shot a seven-under 64 after entering the day at even par to sit in a tie for third heading into the weekend.

She is tied two shots back from the lead at seven under with Sweden's Anna Nordqvist, one shot ahead of fellow Swede, amateur Ingrid Lindblad, who posted a one under score on Friday after setting the U.S. Women's Open record for lowest score by an amateur with her opening round 65.

Lindblad is tied with world number one Ko Jin-young at six under, with South Korea's Kim Sei-young and Thailand's Moriya Jatanugarn one stroke back at five under.

Rounding out the top-10 are the American trio of Ryann O'Toole, Megan Khang and Andrea Lee, along with England's Bronte Law and South Korea's Park Sung-hyun, tied for ninth at four under.

Cameron Smith continued his strong start to the Memorial Tournament on Friday, sitting alone atop the leaderboard on eight under after being one of three players to shoot under 70 on back-to-back days.

The Australian was in a six-way tie for the lead after round one, and pushed on well his second time around, finishing with just one bogey – on the sixth hole – which was sandwiched by birdies on the fifth and seventh.

Smith then birdied the par-five 11th, and the par-three 12th, showing his impressive touch over long and short distances, but where he really made his money was around the greens.

According to Data Golf, Smith had negative strokes-gained off the tee and with his approach shots in round two, but was second overall in strokes-gained around the greens (plus 3.55), trailing only Beau Hossler (plus 4.25). They gapped the field, with nobody else gaining more than plus 2.83 in that shot category.

Sitting one stroke off the lead is American Denny McCarthy and South Korea's Lee Kyoung-hoon, while one stroke further back at six under are round one's joint-leaders Davis Riley, Cameron Young and Luke List, along with Jhonattan Vegas and Billy Horschel.

McCarthy and Vegas joined Smith as the only players to shoot sub-70 in the opening two rounds.

Rory McIlroy headlines the group at five under in a tie for ninth, along with Francesco Molinari, still well within striking distance heading into the weekend.

A strong international group is at four under, including Canada's Mackenzie Hughes, Chile's Joaquin Niemann and South Korea's Im Sung-jae, and they are one stroke ahead of Ireland's Shane Lowry, Mexico's Abraham Ancer and American Will Zalatoris.

Jon Rahm and Corey Conners will still feel like they have a chance at two under, Max Homa and Xander Schauffele finished well inside the cut-line at one under, and Jordan Spieth shot a disappointing 74 on Friday to take an even par score into the weekend.

England's Aaron Rai – who was number one in strokes-gained off the tee on Friday – along with Australian Adam Scott finished right on the cut-line, making it through at two over, but Matt Fitzpatrick (three over) and Collin Morikawa (four over) were not so lucky.

American Mina Harigae is the outright leader after the first round of the U.S. Women's Open with a seven-under 64, but she was arguably outshone by Swedish amateur Ingrid Lindblad.

Harigae had nine birdies with two bogeys – becoming the sixth player to shoot 64 in tournament history – but leads by just one stroke from Lindblad, who shot the best score by an amateur in U.S. Women's Open history with her 65.

Lindblad was spectacular, particularly on the front-nine, where she birdied the first three holes, as well as the eigthth and ninth, before finally registering her only bogey of the round on the 10th. She responded to that adversity in fine fashion, collecting birdies on 12 and 13.

The chasing pack sits two back from Lindblad, with Swedish compatriot Anna Nordqvist tied at four under with Australia's Minjee Lee and America's Ryann O'Toole.

Keeping with the Swedish theme, Lindblad was partnered with legendary three-time U.S. Women's Open champion Annika Sorenstam, who gave the 22-year-old some glowing praise after their round.

"She's authentic," she said. "She's got a special look, but she's a fearless player.

"She's confident in her own game. I know she doesn't shy away from the limelight that maybe I did as a young girl."

American duo Lexi Thompson and Ally Ewing are tied for sixth at three under, and there is an 11-woman logjam sitting inside the top-10, tied for eighth at two under.

World number three Cameron Smith headlines a six-way tie atop the Memorial Tournament leaderboard after Thursday's first round at Muirfield Village.

Smith is joined by American trio Luke List, Cameron Young and Davis Riley, as well as Canada's Mackenzie Hughes and South Korea's Lee Kyoung-hoon.

It is the largest leading group after the first round in tournament history, but they all got to their five-under 67 in different ways. 

Young finished the day second in average driving distance (316.8 yards), behind only Jon Rahm, while Lee, Hughes and Smith finished top-six in putts-per-green-in-regulation.

List was the only member of the leading group to finish with less than two bogeys, and Riley played an all-round game; top-15 in driving distance while being dialled in with his putter down the back-nine, going five-under from the 11th hole to the 17th.

US PGA Championship runner-up Will Zalatoris is part of the three-man group one stroke off the lead, while Max Homa and Canada's Corey Conners are in the logjam at three under.

A star-studded group finished with a two-under 70, including Rory McIlroy, Jordan Spieth, Xander Schauffele and Im Sung-jae, while Chile's Joaquin Neimann is with Collin Morikawa and Jason Day at one under.

Patrick Cantlay and Rahm were even-par, Mito Pereira will need a solid second round to make the cut after a one-over finish, and Hideki Matsuyama was handed his first career disqualification for using a wood with paint on its face – deemed illegal. He was three over at the time of the incident.

Hideki Matsuyama was disqualified from the Memorial Tournament midway through his first round on Thursday after breaching PGA Tour equipment regulations – the first disqualification of his career.

The 2021 Masters champion had just finished the ninth hole of a thus-far disappointing outing in Ohio, and would have made the turn at three-over after making three early bogeys. 

But Matsuyama, who won his first PGA Tour title at the 2014 edition of the tournament, was informed on the 10th tee that markings on the face of his three-wood breached equipment regulations.

Images showed what appeared to be white paint on the club face, which he used throughout his short outing on the course, leading chief referee Steve Rintoul to describe the club as "non-conforming".

Rintoul grouped with other officials to deem the three-wood in breach of equipment rule 4.1a, which states "a substance or any treatment can't be applied to the face of a club which could influence the flight of the ball, the spin, the loft or anything on the ball, how the ball performs".

The 30-year-old, who had never previously been disqualified in his nine-year professional career, refused to comment after being barred from completing his round.

Matsuyama tied for 14th in his unsuccessful defence of hi Masters title, having recovered from a neck injury to feature in Augusta, and will look to bounce back at the Canadian Open, which starts next Tuesday.

English golfer Eddie Pepperell claims stars who sign up for the LIV Golf Invitational Series are making it obvious "what money means to you".

Former world top-50 star Pepperell says many players are taking "a big risk" by aligning themselves with the series that is being funded by Saudi Arabia's Public Investment Fund.

Former U.S. Open and Masters champion Dustin Johnson, 37, is among the 42 confirmed entrants for the first event, which will be held at Centurion Club near London from June 9-11.

Sergio Garcia, Kevin Na, Louis Oosthuizen, Ian Poulter, Charl Schwartzel, Graeme McDowell and Lee Westwood are also set to feature in a tournament that will have 12 teams and 48 players.

There have been claims of the event being an attempt at sportswashing, and while Pepperell did not level that accusation, he suggested a lust for money had to be the prime motivation for players who have gone against the wishes of the PGA Tour and European Tour by agreeing to take part.

"From a ROI [return on investment] perspective, the field for the first LIV event is awful," Pepperell wrote on Twitter. "Obviously they're banking on that changing over time. You have to wonder how long they'll keep pouring that amount of money into this if that change doesn't come quickly.

"Plus, deteriorating financial conditions across the world may have an impact. Nobody will be impervious to what we're seeing and what we'll continue to see economically into the next 18 months.

"The players who have signed up should be upfront and honest about their reasons to do so. And it has to be the money. There's nothing wrong with chasing money or higher salaries, people do it across all industries.

"It's somewhat understandable from the older guys… But to those under 35/40 who have signed up, you have taken a big risk. And it shows to the rest of us (peers included) how little commitment you have to your respective Tours (who have done a lot for you), and ultimately what money means to you."

The inaugural tournament clashes with the Canadian Open on the PGA Tour, an event at which Johnson is a previous winner.

Rory McIlroy described the Canada event and this week's Memorial Tournament as "proper golf tournaments" on Wednesday, as he reflected on the LIV Series line-up.

"I certainly don't think the field is anything to jump up and down about," McIlroy said of the Centurion Club tournament.

Northern Irishman McIlroy has tempered his comments on the LIV Series in recent months, having previously been robust in his opposition.

He understands its appeal to some, but has been quite clear he will not be taking part.

"Some guys are in a position where they are not guaranteed a job next year. It's hard to stay in the top 125, especially when you're in your 40s and maybe don't hit the ball as far as you've used to. As we've seen, it's a young man's game nowadays," McIlroy said.

"So if another entity comes along and says, 'we'll guarantee you this amount for three years', plus you're playing for a ton more prize money, you're playing fewer events and you can spend more time with your family it's very appealing to some of those guys that are in that position."

Phil Mickelson had long been linked with the LIV Series, but the 51-year-old has not played since apologising for comments made about the Saudi Arabia regime and has not been included on next week's start list. The American said in February he was taking a break from golf and did not defend his US PGA Championship last month.

Dustin Johnson is among the 42 confirmed entrants for the first event of the controversial LIV Golf Invitational Series but Phil Mickelson's name was not among the participants for the Saudi-funded competition.

Two-time major winner Johnson is the highest-profile name in three-day event, which will be held at Centurion Club near London from June 9-11.

Sergio Garcia, Kevin Na, Louis Oosthuizen, Ian Poulter, Charl Schwartzel, Graeme McDowell and Lee Westwood are also set to feature in a tournament that will have 12 teams and 48 players.

Johnson's name is perhaps the most surprising, with the former world number one having gone back-and-forth over his participation and issued a statement back in February pledging his future to the PGA Tour.

On Tuesday, his agent David Winkle released a statement quoted by ESPN that read: "Dustin has been contemplating the opportunity off-and-on for the past couple of years.

"Ultimately, he decided it was in his and his family's best interest to pursue it. Dustin has never had an issue with the PGA Tour and is grateful for all it has given him, but in the end, felt this was too compelling to pass up."

Mickelson had long been linked with the event, but the 51-year-old has not played since apologising for comments made about the Saudi Arabia regime. The American said in February he was taking a break from golf and did not defend his US PGA Championship last month.

The series has courted plenty of controversy due to the fact it is being funded by Saudi Arabia's Public Investment Fund, leading to claims of sportswashing.

The inaugural tournament clashes with the Canadian Open on the PGA Tour, an event of which Johnson is a previous winner.

Sam Burns drained a putt from off the green to win the Charles Schwab Challenge in a playoff against world number one Scottie Scheffler.

Despite making no birdies on Sunday, Scheffler was in contention all day after entering the day in the outright lead, but had to battle with the difficult conditions later in the day to post a 72.

Burns was in much better touch, and had the benefit of getting his 18 holes out of the way earlier before the wind picked up, notching a 65 for the round of the day. 

He was one shot back from a four-way tie at 10 under when he finished his tournament at nine under, and he had to wait two hours to find out – first if the field would come back to him – and then if Scheffler could hold on for the playoff.

Scheffler needed to save a number of tough pars down the back nine, including out of the bunker on the 18th hole to force the playoff, which he did by sinking a clutch five-footer.

In the playoff, after a pair of solid drives, Scheffler found the green a long way from the hole, while Burns put his approach just off the back of the putting surface. Approaching three hours since his last putt, Burns drained an incredible tournament-winner, with Scheffler not able to match him from distance.

Speaking to the media after securing the win, Burns said it was a hard-fought result.

"I think, just with the conditions today, and how tough it was playing, I'm just so proud of the way we hung in there," he said.

"I just played such a good round of golf today, and [caddie] Travis [Perkins] did a good job of keeping us in it, especially after hitting a foul ball at 12 which killed our momentum. Hitting that putt – that's just icing on the cake."

It is 11 years since Burns attended Colonial Country Club in person to witness David Toms win the Crowne Plaza Invitational, and he said it is hard to believe he is a champion at the same course.

"I don't know if I would've believed you – I remember that week like it was yesterday," he said.

"To finish it off here, and have [Toms'] family here… to add my name on that list now is really cool."

Scheffler's playing partner Brendon Todd finished one stroke outside the playoff, alone in third at eight under, while American trio Tony Finau, Davis Riley and Scott Stallings collected top-five finishes, tied for fourth at seven under. Finau and Burns were the only two players to shoot 67 or better in the final two rounds as the conditions worsened throughout the weekend.

A strong group rounded out the top-10, with pre-tournament favourite Jordan Spieth and US PGA Championship main character Mito Pereira headlining the five-man bunching in a tie for seventh at five under,

Spieth, Riley and Im Sung-jae – who was part of the logjam at three under – were the only three players to shoot 70 or better in all four rounds.

Norway's Victor Hovland was one of two players to finish at two under, while New Zealand's Danny Lee tied Burns for the round of the day, with his Sunday 65 bringing him to one under for the tournament.

Harold Varner III was part of the four-way tie for the lead at 10 under through 11 holes, but went triple-bogey, double-bogey, triple-bogey over his next three holes to plunge down the leaderboard and finish at even par.

Talor Gooch and Webb Simpson joined him at even par, Tommy Fleetwood finished at one over, and Collin Morikawa never shot worse than 71, but never shot better than 70 to finish two over.

Victor Perez secured his second DP World Tour title and first since 2019 after defeating Ryan Fox in a dramatic play-off at the Dutch Open.

Perez and Matt Wallace, searching for a first tour-level victory since 2018, sat one shot clear of a four-man chasing pack heading into the final day at Bernardus Golf.

Wallace subsequently fell away from the lead as he carded a level-par 72 to finish on 10-under, as Fox and Perez jostled for top spot.

Australian Fox, who started the day one off the lead, birdied four holes and eagled the par-five 12th but recorded a double-bogey on the 18th hole, opening the door for Perez to send the competition to a play-off.

Perez duly obliged by producing a wonderful long-range putt to birdie the par-three 17th, but was only able to par the final hole to conclude on 13-under, leaving a one-hole shoot-out to decide the winner.

The pair could not be separated on their first three returns to the 18th tee, the designated play-off hole, both producing birdies either side of a par before being sent to the 17th to settle the tie.

Perez then delivered another magnificent birdie putt and Fox could only make a three, leaving the Frenchman ecstatic after finally claiming victory.

"There was a fair amount of fortune, I've got to be honest with myself, holing out those long putts in the play-off," said Perez, who moved to 24th in the DP World Tour Rankings with the win.

"I just tried to focus on me all day, that's all I can do, is try to keep a champion mindset and hit good shot after good shot.

"The chips were going to fall where they were going to fall, it's almost impossible to predict what is going to happen in golf: guys come out of nowhere and win tournaments and guys take huge leads.

"You just have to focus on you and not look at the board and I was just fortunate to fall on the right side today."

Meanwhile, Poland's Adrian Meronk ended in third after managing 68 in the fourth round to finish 12-under, with Germany's Marchel Schneider one shot behind in fourth.

Sebastian Soderberg was part of the initial chasing pack but, on a low-scoring day, his one-under 71 only proved enough to share fifth place with Wallace.
