Brooks Koepka feels he is finally back to full health following a serious knee injury that had crippled him over the past two years, claiming a share of the lead after Thursday's opening round at the Masters.

Koepka, a four-time major champion, shot four birdies on his front-nine and four more on his back-nine to go with a solitary bogey in an impressive seven-under 65.

There were warning signs that the 32-year-old may be in for a good week, coming off a victory at LIV Golf Orlando where Koepka became the new tour's first ever two-time winner.

His performance this time was in stark contrast to his efforts at the last two editions of the Masters, where Koepka missed the cut both times, but he told the media after his round that his health made those years complete write-offs.

He shared details of the darkest moments from his recovery, where he could barely get out of bed, and would be in tears while biting down on a towel as his physical therapist tried to bend his knee.

"I just wrote the last two years [at the Masters] off," he said. "I came here three weeks after surgery [in 2021], and last year I wasn't anywhere near it, but I'm healthy now, I've put that behind me, and I'm not too worried about the last two years.

"It's all injury-based. Any athlete, anybody that's going through something where you can't even bend your knee. 

"I'll spare everybody the details of what actually happened – it was pretty gruesome, right – and they told me I could have a surgery that would be pretty much a year and a half [recovery time].

"Then you create bad habits, and there's frustration, and you just feel like you're never going to be healthy.

"I wish I had celebrated the kind of little milestones along the way, instead of thinking I could just power through it… so yeah, it was definitely frustrating, but once you feel good, everything changes."

He said he realised early that he was in for a great day after making a sharp start on a course that was "quite gettable".

"Honestly I think it was just the start," he said. "I got off to a good start – any time you're two under through three it's a good start – so I felt good, and I just kind of piggybacked off that momentum.

"I'm very happy with the way I played. I drove the ball nicely, left it in some good spots, and even missed quite a few putts… it could've been really low, but I'll take it. Seven's pretty good."

Jon Rahm, Brooks Koepka and Viktor Hovland are tied for lead at seven under after Thursday's opening round at the Masters.

It was a shaky start for world number three Rahm as he stumbled to a double-bogey on the first hole, but he birdied the next two to quickly even out his card, before rattling off another five birdies and an eagle the rest of the way.

Koepka, a four-time major champion, is riding high after emerging victorious in last week's LIV Golf Orlando to become the breakaway tour's first ever two-time winner, and he looked terrific with eight birdies and one bogey.

Hovland was the only of the trio to go bogey-free, with the 25-year-old Norwegian now in a great position to make a run at his first major title.

They have a two-stroke lead on the chasing pack, with Australia's former world number one Jason Day shooting a bogey-free, five-under 67, and he is joined in a tie for fourth by Cameron Young.

Tiger Woods carded back-to-back birdies on the 15th and 16th holes to salvage a disappointing two-over 74, leaving him with work to do on Friday if he is to make the cut.

World number one Scottie Scheffler is part of a loaded logjam tied for sixth at four under, which also includes world number seven Xander Schauffele, former Masters champion Adam Scott, WGC Match Play winner Sam Burns, and surprising rookie Sam Bennett.

Three-time major champion Jordan Spieth is at three under with two-time major champion Collin Morikawa, reigning British Open champion Cameron Smith is at two under with reigning PGA Championship victor Justin Thomas, and Phil Mickelson is joined at one under by fellow Masters champions Hideki Matsuyama, Patrick Reed and Dustin Johnson.

Shot of the day

While Bennett's eagle chip-in, or Rahm's long iron setting up a five-foot eagle putt were worthy contenders, neither had the degree of difficulty of Hovland's par save on the 10th hole.

Landing in a horrible spot in the rough behind a bunker, with almost no green to work with, Hovland played a feathery flop into the fringe and allowed it to trickle next to the hole for an unlikely par.

A little birdie told me… 

It was a memorable day for Bennett, as the 23-year-old amateur began his first round at the Masters with a birdie on the first, an eagle on the second and another birdie on the sixth to tie the best front-nine score by an amateur at Augusta (32).

Meanwhile, after his best major finish last season with a T4 at The Open, Hovland tied his best round at a major, and set a new personal best around Augusta with his seven-under 65.

Joining him at the top of the leaderboard, Rahm will be trying to make history as the first player to ever win the Masters after double-bogeying their opening hole.

Tiger Woods was in "constant" pain during a first round of the Masters that left him facing a battle to make the cut.

Woods has won a third of his 15 major titles at Augusta National, but the legendary American may not be in Georgia for the weekend after a disappointing start.

The 47-year-old signed for a two-over 74 after a fifth bogey of the day at the 18th in Georgia, where Viktor Hovland, Jon Rahm and Brooks Koepka capitalised on great conditions to lead at seven under.

Woods defied the odds to resume his career after suffering serious leg injuries in a car accident two years ago.

One of the all-time great revealed he felt "sore" and was troubled throughout his opening round of the first major of 2023 on Thursday.

Reflecting on his round, he said: "Most of the guys are going low today. This was the day to do it.

"Hopefully tomorrow I'll be a little bit better, a little bit sharper, and kind of inch my way through it.

"This is going to be an interesting finish to the tournament with the weather coming in. If I can just kind of hang in there, maybe kind of inch my way back, hopefully it will be positive towards the end."

Cameron Young and Jason Day were two shots behind the leading trio, while defending champion Scottie Scheffler was three under through 14 holes.

Shane Lowry, Xander Schauffele, Adam Scott and amateur Sam Bennett are among a host of players well poised on four under, while Rory McIlroy has work to do at one over through 14.

Jon Rahm birdied the last hole of his first round to join Viktor Hovland in a share of the Masters lead.

Hovland held a three-shot advantage at one stage as he started the first major of the year with a magnificent seven-under 65 on Thursday.

Rahm matched the Norwegian's round to become the co-leader at Augusta National after starting with a double bogey.

The 2021 U.S. Open champion eagled the par-five eighth to go three under and fire a warning to the rest of the field.

Rahm birdied the 13th, 15th and 16th before rolling in a short putt for another gain at 18 following a brilliant approach shot.

Hovland had earlier signed for his lowest Masters round and his joint-best in a major, ending his day without a solitary bogey in great conditions.

Cameron Young and Brooks Koepka are just two shots behind the leading duo, with fellow American Sam Burns also five under through only eight holes.

Jordan Spieth, Shane Lowry, Xander Schauffele, Adam Scott, Joaquin Niemann and Sam Bennett are well poised on four under.

Bennett matched the record for the best front nine by an amateur in the Masters, hitting the turn in 32.

Defending champion Scottie Scheffler was two under approaching the turn, while Rory McIlroy and Tiger Woods are one over and two over respectively in Georgia.

Will Zalatoris withdrew from the prestigious event due to injury.

Brooks Koepka became the first multiple winner in LIV Golf's short history after securing a one-stroke victory at LIV Golf Orlando on Sunday with a score of 15 under.

Koepka, a four-time major champion, won his first event on the new tour back in October at LIV Golf Jeddah, and he came into his third and final round in Orlando leading by three strokes after a pair of six-under 66s on Friday and Saturday.

He was bogey-free with four birdies through 14 holes as he tried to close it out, but Sebastian Munoz – who set the LIV Golf single-round scoring record with a nine-under 62 on Friday – was chasing him down.

Koepka's first bogey on the 15th cut his lead to one, but Munoz also bogeyed to briefly give back the two-stroke buffer, before birdieing the 16th to set up a tense finish.

Munoz appeared to throw his chances away when he sailed his bunker shot on 17 well past the green, but he got up-and-down for par to keep it at one shot going onto the last.

Both players found the middle of the green in regulation, and while Munoz gave himself a tap-in par, Koepka left himself a sweaty six-footer for the win, but made no mistake.

For the victory, Koepka took home a $4million winner's cheque, as well as his share of the second-placed team prize as his Smash GC finished one stroke behind Munoz's Torque GC.

Dean Burmester and Patrick Reed were tied for third at 12 under, while Dustin Johnson banked a top-10 with a solo seventh at 10 under.

After briefly climbing up into the top-five at 10 under, Cameron Smith went bogey, bogey, triple-bogey to fall back five shots.

Former Masters champions Bubba Watson and Patrick Reed do not expect any issues when LIV Golf International Series and PGA Tour players meet at the famous Augusta major.

Watson and Reed are among 17 LIV Golf stars set to feature at The Masters, with six of those rebel golfers automatically qualifying with a lifetime exemption after winning the tournament.

Cameron Smith, Brooks Koepka and Bryson DeChambeau are also part of the breakaway league but able to play due to winning a major in the last five years.

Major competitions are the only place the two sets of golfers can feature after the PGA banned those who joined the Saudi-backed rebel series for record purses and 54-hole events.

But Reed, speaking ahead of the LIV Golf League event at Orlando that starts on Friday, does not foresee any animosity when the two groups tee off at the Augusta National Golf Course on April 6.

"It's one of those things, the media and the storylines are going to be obviously LIV versus PGA Tour and all that kind of stuff," 2018 Masters champion Reed said.

"But really the majors, that's all the guys that come in, top players in the world are going and playing against each other, no matter where they come from.

"It doesn't matter what tour they're on or anything; it's the top guys going and trying to play for one of the most coveted events in the world.

"For us, at least for myself, it's going to be business as usual going out and playing. Would I like to have LIV be up at the top? Of course.

"But really at the end of the day, it's all of us going in there and just trying to play the best golf we can and be ready for the four biggest weeks of the year."

Watson, a two-time Masters victor, echoed Reed's sentiment as the American reiterated the only issues between players are coming from media speculation.

"It's only awkward in the media," Watson said. "I've talked to people that are going to be there. I'm going to sign up with Jason Day and Cam Young in the par-three and some guys have already asked me to play some practice rounds.

"The media is the only one that is pushing it. I have nothing against anybody. If you change jobs, I'm not mad at you."

Koepka was another big-name superstar LIV managed to secure from the PGA and the four-time major winner says it would be a "big statement" for whoever wins in Georgia, regardless of allegiances.

"Anytime you win the Masters, it's going to be a big boost off the golf course for you," Koepka said. "I don't care who you are. Look at anybody that's won it, I guarantee they would say the same thing.

"I can't speak for what would happen because I don't know the future, but I'm assuming that would be a massive, massive boost for any team, player, individual, whatever, it doesn't matter what it is, it's going to be a big boost.

"Anytime you win The Masters or The Open, that's usually a pretty big statement."

LIV Golf players will be able to play in the 2023 Masters provided they meet the tournament's existing entry criteria.

Phil Mickelson, Sergio Garcia, Bubba Watson, Patrick Reed and Charl Schwartzel joined the controversial Saudi Arabia-backed breakaway LIV Golf series this year, but will be eligible to compete at Augusta next April due to being former Masters champions.

Cameron Smith has been invited to play due to his Open triumph this year, while Bryson DeChambeau and Brooks Koepka can also tee off in Georgia as a result of their major successes.

Augusta National Golf Club Fred Ridley said in a statement: "From its inception in 1934, the purpose of the Masters Tournament has been to benefit the game of golf.

"Each April, the Masters assembles the world’s leading golfers to compete for the Green Jacket and a place in history.

"Regrettably, recent actions have divided men’s professional golf by diminishing the virtues of the game and the meaningful legacies of those who built it.

"Although we are disappointed in these developments, our focus is to honour the tradition of bringing together a pre-eminent field of golfers this coming April.

"Therefore, as invitations are sent this week, we will invite those eligible under our current criteria to compete in the 2023 Masters Tournament.

"We have reached a seminal point in the history of our sport. At Augusta National, we have faith that golf, which has overcome many challenges through the years, will endure again."

Mickelson did not play in the Masters this year as he took time out from the sport after coming in for huge criticism over comments he made about Saudi Arabia's human rights record before joining LIV Golf.

Dustin Johnson capped off a huge year by pipping Cameron Smith to clinch victory for the all-American 4 Aces GF at the LIV Golf Miami Team Championship on Sunday.

Johnson nailed a routine final putt of the season to cue the celebrations for his team, featuring Patrick Reed, Lalor Gooch and Pat Perez whom all had solid rounds in Sunday's Championship.

The Aces were crowned the inaugural LIV Golf team champions at Trump National Doral by one shot ahead of Cameron Smith's Punch GC, with Brooks Koepka's Smash GC and Louis Oosthuizen's Stinger GC well back.

The triumph capped a money-spinning season for two-time major winner Johnson, finishing with more than $35 million in earnings.

"It's been amazing," Johnson said. "This week's been incredible. This whole season has gotten better and better and obviously this finale has been unbelievable."

Among the four Aces players, they scored a combined seven-under 281 in the singles stroke-play on Sunday, with Johnson, Reed and Perez all finishing two-under-par, while Gooch was one under, having started the round with three birdies in his first for holes.

Johnson's team edged out Punch for whom Smith carded a round-best seven-under-par 65 with eight birdies. That was offset by Marc Leishman's 74, Wade Ormsby's 73 and Matt Jones' 70 as Punch combined for a six-under 282.

Smith, who won this year's Players' Championship before joining the LIV Tour, went head-to-head with Johnson.

Smash finished 11 strokes behind with a combined four-over 292, with Jason Kokrak their best with a four-under-par 68.

Stinger were a further six shots behind Smash with a combined 10-over 298, despite one-under rounds from Oosthuizen and Charl Schwartzel, with Branden Grace shooting an 80.

Louis Oosthuizen beat Bryson DeChambeau 1up in 23 holes to secure a spot for Stinger GC in the LIV Golf Championship in Miami on Sunday after a 2-1 team semi-finals win on Saturday.

Saturday's semi-finals were match play, with Sunday's Championship to be stroke play, but Oosthuizen and DeChambeau offered plenty of drama in their singles match at Trump National Doral.

With Stinger and the Crushers tied at 1-1, the pair could not be split until the fifth extra hole, with Oosthuizen having a long-range putt for victory fall short on the 18th hole.

But the South African swooped when DeChambeau's tee shot on the fifth extra hole found the water, with Oosthuizen finishing the job.

"At the end I think the adrenaline took over in the last few holes," the South African said. "It was a great match.

"I don’t know how many birdies we made, but very relieved now. I thought the boys had it covered so when I saw Branden [Grace] lost and I'm like 'oh boy I've got to do something here', so very chuffed."

Grace was beaten by Paul Casey in their singles match, but Charl Schwartzel and Hennie du Plessis had won 2up in the alternate shot against Charles Howell III and Anirban Lahiri.

Dustin Johnson and his 4Aces GC also advanced to Sunday's decider with a 2-1 win over Cleeks GC.

Pat Perez and Talor Gooch held off Graeme McDowell and Richard Bland in extra holes to clinch the winning point.

Cameron Smith's Punch GC knocked off Sergio Garcia's Firebirds GC 2-1, while Brooks Koepka's Smash GC were too good for Majesticks GC 3-0.

In the headline matchup from the first day of the LIV Golf Team Championship, Cameron Smith finished 1up against Phil Mickelson to help Punch GC advance past Hy Flyers GC in Friday's quarter-finals.

The format for the Team Championship has the top-four teams automatically advancing to Saturday's semi-finals, while teams five-through-12 battled it out on the opening day.

With teams of four, it meant there would be two one-on-one match play rounds, as well as a two-on-two foursomes played with alternate shot rules, with the team who wins two-out-of-three getting to advance.

For Punch GC, Smith was matched up with Mickelson, and they went onto the 18th hole tied, before Mickelson left the door open with a bogey to finish his round, allowing Smith to secure one win for his team with a par.

Smith's Australian teammate Marc Leishman enjoyed a much more dominant victory, working his way to a 4up lead through seven holes on his way to a 4 and 2 win against J.J. Wolf. Hy Flyers did salvage one point despite getting eliminated, with the duo of Bernd Wiesberger and Cameron Tringale beating Wade Ormsby and Matt Jones 3 and 2.

It was a three-to-zero clean sweep for Majesticks GC, with Ian Poulter beating Kevin Na 4 and 2, Lee Westwood defeating Sihwan Kim 4 and 3, and the team of Sam Horsfield with Henrik Stenson collecting a 4 and 2 victory over Sadom Kaewkanjana and Phachara Khongwatmai.

For Smash GC it was Chase pulling through for the Koepka clan as Brooks Koepka fell convincingly in a 4 and 3 loss to Niblicks GC's Harold Varner III.

But Smash GC will move on to the semi-finals after Chase Koepka and Jason Kokrak beat Turk Petit and Hudson Swafford 2 and 1, while Peter Uihlein hammered James Piot 5 and 3.

In the last quarter-final, Cleeks GC booked their semi-final matchup against Dustin Johnson and the top-seeded 4 Aces GC after winning two-out-of-three against Torque GC.

Joaquinn Niemann did all he could for Torque GC, cruising past Shergo Al Kurdi 5 and 3 after Al Kurdi stepped in for Cleeks GC captain Martin Kaymer, who was a late withdrawal.

But Laurie Canter kept his team in it with a narrow 1up win over Jediah Morgan, before Graeme McDowell and Richard Bland put Torque GC through to the next round with a 2up victory against Scott Vincent and Adrian Otaegui.

The eight remaining teams will compete in the same format in the semi-finals, with Cameron Smith against Fireballs GC captain Sergio Garcia shaping up as the main event.

Brooks Koepka edged out Peter Uihlein in a play-off to clinch the final individual prize of the inaugural LIV Golf Invitational Series on Sunday.

Two birdies on Koepka's front nine in Jeddah set him up well to push on for glory, but the American slipped up after the turn at Royal Greens Golf and Country Club.

A birdie on the 10th was followed by three successive bogeys, and though Koepka recovered to birdie on the 15th and the last to finish at 12 under par, he had provided his rivals with an opportunity to catch up.

Overnight leader Uihlein was one of those to take advantage, with a clean back nine seeing the 33-year-old bounce back from carding two double bogeys earlier on in his round, with his final score of 70 enough to force a play-off with Smash GC team-mate Koepka.

While it was good news for Smash GC, who secured a six-shot win to boost their form ahead of the Team Championship in Miami later this month, there had to be a loser, and after three holes with no give, Uihlein found a bunker.

Having rescued himself from a similar situation on the previous play-off hole, this time Uihlein could only clip a shot into the water, handing four-time major winner Koepka the chance to putt for victory.

"The last two years – they haven't been fun," an emotional Koepka said.

"So it's been a long road, I'm super excited. My whole team, we got the band back together a couple of months ago, this is for them.

"I didn't know if my career was over, for a half-second. I wasn't sure when I was going to play. It's nice to come back and win."

Joaquin Niemann went round in 65 to finish one shot behind the leading pair, tied with Sergio Garcia.

Inaugural LIV Golf champion Dustin Johnson came in at 10 under, alongside Matthew Wolff, while Bernd Wiesberger joined Niemann in recording 65.

Peter Uihlein seized a one-stroke lead to carry into the final round of LIV Golf Jeddah after a seven-under-par 63 in Saudi Arabia on Saturday.

The American leapfrogged compatriot Brooks Koepka at the top of the leaderboard after an eagle and birdie on his final two holes took him to 12 under.

The only blot on his copybook at the Royal Greens Golf Club was a double bogey at the par-four 13th.

Koepka, who led after the first day of competition on Friday, carded a three-under round of 67 to stay in touch.

Two shots further back are South Africa's Charl Schwartzel and Sergio Garcia, with the Spaniard posting a bogey-free 64.

The inaugural individual LIV Golf champion Dustin Johnson stood five shots off the lead after a round of 65.

It was a disappointing day for Henrik Stenson, meanwhile, with the Swede sitting in last place after going round in 75, five over and for the tournament.

Brooks Koepka holds a two-stroke lead of LIV Golf Jeddah after finishing the opening round eight under par in Saudi Arabia.

The four-time major champion made eight birdies in his round of 62 and did not go over par on any hole to head into the weekend ahead of second-placed Charl Schwartzel, while Patrick Reed is tied for third with Hideto Tanihara and Peter Uihlein at three shots off the lead.

The inaugural individual LIV Golf champion Dustin Johnson is T16 on two under par, alongside Open champion and world number two Cameron Smith.

Johnson, who has collected 121 points across the season, struck five birdies, but a double-bogey on the par-three eighth set him back.

Phil Mickelson and Lee Westwood fared slightly better at three under, the latter not carding any bogies in his round.

LIV Golf Bangkok winner Eugenio Lopez-Chacarra struggled to back up his performance in Thailand and is T28 at one under par, seven shots back from Koepka. Bryson DeChambeau, meanwhile, only managed a par 70.

After withdrawing from LIV Golf Bangkok with injury, Branden Grace carded a one-over-par round on his return to action.

Eugenio Lopez-Chacarra claimed the LIV Golf Bangkok title after carding a final-round 69 to win by three strokes on a weather-affected final day.

The 22-year-old took a five-shot lead into the final round and did enough to hold off late charges from the likes of Patrick Reed and Paul Casey, the latter of whom will be left to rue an opening round of 71 after shooting 65 on both the second and third days.

Nobody bettered Lopez-Chacarra's first and second rounds of 65 and 63 respectively, and he overcame two bogies on the front nine to finish three under on the final day and seal victory, maintaining his focus despite play being suspended for an hour and a half because of a storm in the area.

The Spaniard was a high-ranked amateur before joining the controversial Saudi-backed tour in June and now earns his first professional championship, as well as a $4million purse.

Richard Bland and Branden Grace formed part of a leading trio with Lopez-Chacarra on seven under after the opening round, but Grace withdrew with injury on Saturday while Bland could not follow up his first-day success, losing pace on the eventual winner to finish joint-third – alongside Casey and Sihwan Kim and a stroke behind second-placed Reed.

Four-time major champion Brooks Koepka was joint-eighth at 13 under, while Bryson DeChambeau ended 14th at 10 under.

Other big names were way off the pace, with Phil Mickelson 10 shots behind Lopez-Chacarra and 2022 Open Championship winner Cameron Smith finishing a disappointing tournament tied for 41st at four under.

Eugenio Lopez-Chacarra will take a five-stroke lead into the final round at LIV Golf Bangkok after ending a brilliant second day in Thailand at 16 under par.

Lopez-Chacarra was one of a leading trio on seven under after the first round, but Richard Bland was unable to keep up with the Spaniard and Branden Grace withdrew after just three holes on Saturday due to an acute muscle strain.

Bland is one of four five shots off the lead with Sihwan Kim, Patrick Reed and Harold Varner III – while they may not be completely out of the running yet, the chasing pack need Lopez-Chacarra to lose momentum.

If his form from the first two rounds is anything to go by, there is little hope of such a collapse, with no one in the field bettering his respective scores of 65 and 63.

Saturday's 63 was nine under par as the 22-year-old – who was a high-ranked amateur before joining LIV Golf in June – carded seven birdies and an eagle, which was holed from the sand on six, and avoided a single bogey.

Those trailing Lopez-Chacarra will be hoping the Madrid native's inexperience leads to a blip on Sunday.

Four-time major winner Brooks Koepka is one of those who will aim to propel himself into contention as he sits on 10 under for the tournament, though victory will require something special.

Few other big names retain much of a chance of glory, however, with Bryson DeChambeau at seven under and Phil Mickelson another shot back.

Sergio Garcia and Dustin Johnson are among a group on four under, while 2022 Open Championship winner Cameron Smith is way down near the bottom of the standings at two under.

If Lopez-Chacarra can hold his nerve on Sunday, he will have gone from amateur golfer to winner of a $4million purse within four months.
