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.

Scottie Scheffler is now the proud owner of a green jacket after winning the Masters with a terrific performance in the last round – even if he wobbled on the 18th green.

Scheffler, 25, finished 10 under overall and shot 71 on Sunday after a double bogey at the last, winning his fourth career PGA Tour title after landing his first just 57 days ago.

A terrific chip-in on the third hole helped him find his footing after a couple of wayward drives early on, but his ability to recover from less-than-ideal situations was on full display on the first nine.

He would birdie the seventh hole on the way to a bogey-free front half, before his first slip-up came with a bogey on the 10th as he missed a makeable par putt. He lost his putting poise on the final green, but had enough shots in hand that it hardly mattered a jot.

The final day shaped up as a two-horse race between Scheffler and Cameron Smith, but any chance Smith had at mounting a comeback went up in smoke as his tee shot on the par-three 12th found the water.

Smith went on to triple-bogey the hole, and fell apart from that point, pulling drives into the trees as his fight turned from a chance to win to a battle to hang on in the top five.

The surge of the day came from Rory McIlroy, who shot one off the course record with an eight-under 64 to finish outright second at seven under.

McIlroy went bogey-free, with birdies on one, three, seven, eight, 10 and 18, and an eagle on 13.

He capped off his round with a remarkable chip-in from the bunker on 18 – only for his playing partner, Colin Morikawa, to do likewise to put the finishing touches on a 67 to earn outright fifth place at four under.

Also finishing inside the top five was Shane Lowry, who finished with a three-under 69 to tie with Smith for third on a five-under aggregate, despite a triple bogey on the par-three fourth.

There is nothing in golf quite like The Masters.

Arguably the most prestigious of the majors, Augusta National becomes the centre of the sporting world once more over the weekend, as the famous green jacket goes up for grabs again.

In 1997, Tiger Woods won his first major when he triumphed in Georgia, and 25 years on he is set to make a sensational comeback from injury.

But Woods is not the only name to look out for.

The favourites

Let's start from the top. Scottie Scheffler is the world's new number one and he heads into the weekend on the back of three victories in his last five events, having not finished worse than T-19th in his six major appearances since 2020.

Scheffler said he has been resting up at home ahead of travelling to Augusta, where he joked he has already been brought down a peg or two.

He told Sky Sports: "I've been humbled a couple of times already, showing up here. The guy who picked me up in the cart this morning called me Xander, so that brought me down to earth real quick! It's been great, really looking forward to this week."

The Xander in question is Xander Schauffele. He finished T3 last year, three shots back from the champion Hideki Matsuyama, and was looking good on his final round until he sent a ball into the water on the 16th, but he won gold at the Tokyo Olympics and comes into the tournament in strong form.

Reigning champion Matsuyama cast doubt over his participation when he withdrew from the Texas Open with a neck problem, meanwhile, which may hinder his title defence.

Brooks Koepka has won four majors, but did not make the cut last year and will be out to put that right this time around, having defeated Jon Rahm in the WGC-Match Play last 16. 

Rahm has finished in the top 10 in each of his last four Masters appearances. However, the Spaniard has not won a tournament since triumphing in the US Open last year, but did secure a place in the top 10 in all four of last year's majors.

Dustin Johnson failed to make the cut in 2021 in a torrid title defence. He had dropped out of the top 10 up until an impressive performance at the WGC-Match Play moved him up to number eight, and he'll be determined to rekindle the form that saw him clinch the green jacket in 2020.

Viktor Hovland is ranked fourth in the world, though his weak chipping game may prove costly to his chances at Augusta, while Collin Morikawa cannot be discounted for a third major title and Justin Thomas will be out to win a second major having won the US PGA Championship in 2017.

The outsiders

Augusta is where golfers can shoot to stardom over the course of four spectacular days, and there will be plenty of the field who fancy their chances despite not being among the bookmakers' favourites.

One such player capable of a challenge is Cameron Smith. The Australian is ranked at a career-high six, won the Players' Championship last month and has finished inside the top 10 in three of the last four Masters.

Will Zalatoris, meanwhile, comes into the weekend with the best SG (strokes gained, which compares a player's score to the field average) tee-to-green* statistics on the PGA Tour this season, with his 1.767 average just edging out Thomas, and he came second on his Masters debut in 2021.

Zalatoris only has one pro win to his name so far but the 25-year-old has largely impressed at the majors. He finished T2 in 2021 at Augusta and T8 in last year's PGA Championship, while recording a T6 finish in the 2020 US Open.

Rory McIlroy's Masters record is frustrating. It is the only major the former world number one has not yet won. He finished in the top 10 six times between 2014 and 2020 before missing the cut last year, and now he'll have another stab at sealing a career Grand Slam, though his best finish this season has been third in the Dubai Desert Classic.

Only five players have previously completed a clean sweep of the majors, and McIlroy has not won one of the big four events since 2014.

Russell Henley will feature for the first time since 2018 after 12 top 10 finishes in the past year, and he has finished in the top 25 at Augusta three times, while Bryson DeChambeau is going to compete despite missing a chunk of the season with a hip problem. He finished T46 on three-over-par in 2021.

Marc Leishman finished fifth a year ago, improving on T13 from 2020, and Sergio Garcia will at least hope to make the cut for the first time since he won in 2017. Perhaps if the Spaniard can just make the weekend, he can go all the way again?

The return of the king

As far as comeback stories go in sport, Woods has already provided one of the very best.

In 2019, against all odds following years of back issues and surgery to fix the problems, Woods won The Masters for a fifth time in his illustrious career, taking his total of major victories to 15. He trails only Jack Nicklaus in that regard.

But this comeback might just top the lot.

The 46-year-old admitted he cheated death in a major single-car crash in February 2021, which left him with serious leg and foot injuries. Woods was unable to walk unaided for several months and has not played serious golf since, but he is all set for a remarkable return on the biggest stage of them all.

It will be his first appearance in any tournament since he played at Augusta in November 2020. Since winning his maiden major a quarter of a century ago, Woods has claimed nine more major titles than any other player, while he is one of only three players to win successive Masters titles (2001 and 2002).

Woods has never failed to make the cut in 21 appearances, and even if he does not challenge at the top of the leaderboard this time around (though you would not put it past him) his comeback is already the story of the weekend.

Ryan Palmer holds a two-stroke lead over the field after the second round of the Valero Texas Open.

Palmer, who shot four under in round one, finished with a six-under 66 to move to 10 under.

The American finished the round bogey-free, and three times carded back-to-back birdies on the second and third, eighth and ninth, and 14th and 15th.

Speaking to the media after his round, Palmer said the key to his success is to limit the severity of his mistakes.

"It's a golf course – if you get it off-line, you're going to struggle," he said. 

"I was able to keep the ball in front of me. When I've missed fairways, I've gotten fortunate breaks, I think. 

"[This] weekend, it's a matter of just avoiding those big misses."

Kevin Chappell worked his way into a three-way tie for second after he shot 65 for the best round of the day, and he is joined at eight under by South Africa's Dylan Frittelli and American Matt Kuchar.

Chappell – who is ranked as the world number 547 – played the course beautifully, nabbing an eagle on the par five second hole before going bogey-free and birdieing the eighth, ninth, 12th, 15th and 17th.

The leader after round one, Russell Knox, had a poor day, bogeying four of his first six holes on the way to shooting 76, dropping down to three under and a tie for 27th.

With the cut-line at even par, Jordan Spieth followed up his even par first round with a 70 on Friday to sneak into the frame.

Plenty of notable names who will hope to contest the US Masters crown next week failed to make the cut, including Jason Day, Rory McIlroy, Rickie Fowler and Bryson DeChambeau.

Hideki Matsuyama's defence of his Masters title has been left in doubt after a neck injury forced the 30-year-old to withdraw from the Valero Texas Open.

Matsuyama became the first male Japanese golfer to win a major championship with last year's success at Augusta National, edging out American trio Will Zalatoris, Xander Schauffele, and Jordan Spieth in the final round for a one-stroke victory.

However, with less than a week remaining until the 2022 edition of the Masters begins on April 7, Matsuyama withdrew nine holes into his second round in San Antonio, citing a neck injury. 

Reports have suggested that the 30-year-old has suffered a recurrence of the same injury which kept him out of The Players Championship last month, eventually won by Australia's Cameron Smith.

Matsuyama's most recent result saw him tie for 20th position at the Arnold Palmer Invitational, and he has won two PGA titles since last year's Augusta triumph, winning the Zozo Championship on home soil last October before lifting Hawaii's Sony Open in a play-off in January.

Matsuyama sits 12th in the world rankings, and has made the top 10 in four of the 10 PGA events at which he has featured in the 2022 season.

Russell Knox's bogey-free 65 earned him top spot on the Valero Texas Open leaderboard after the first round of action at TPC San Antonio.

The Scotsman was excellent all day, highlighted by his four consecutive birdies starting on the 12th hole to finish seven under.

He is one stroke ahead of Denmark's Rasmus Hojgaard, who eagled the par-five 18th to finish at six under and make up for his double-bogey on nine.

Speaking to the media after his round, Knox spoke about getting control of his driver, and the potential to play in next week's US Masters.

"I would love to win and get to play next week," he said. 

"I know my game is good, so I've got to keep playing well and see if I can have a great finish.

"I've been a little more consistent tee to green. I'm back to kind of feeling like the way I should be playing, which has been nice.

"Off the tee's been kind of important for me. Over the last couple years I just kind of got off track slightly, hitting a few wayward tee shots.

"I've worked hard with my coach, Mark McCann, and we've really gone back to fundamentals, got my set-up correct and it just gives me the freedom to kind of swing away.

"I know it's never going to be perfect, but the last couple months it's really been a strength of mine again."

Matt Kuchar and Englishman Aaron Rai are in a four-player tie for third at five under, with India's Anirban Lahiri and Australian Matthew Jones part of the large contingent at four under.

In-form Canadian Corey Conners finished tied with Richard Bland and Tony Finau with a big group at two under, with Ian Poulter and Keegan Bradley one shot further back.

It was an up-and-down round for Rickie Fowler, with his bogey on 18 forcing him to accept even-par for the day, which he shared with stars Rory McIlroy and Jordan Spieth.

Bryson DeChambeau and Lee Westwood highlighted the group at plus one, while Jason Day and Hideki Matsuyama will be fighting to make the cut after carding plus two.

Hideki Matsuyama produced a stunning second shot on the first playoff hole to claim victory at the Sony Open in Hawaii as he triumphed over Russell Henley.

The reigning Masters champion had trailed by five strokes on the back nine but produced a surge capped with a birdie at the last to force a playoff with Henley after both finished 23 under par.

Henley's putt on the 18th to win the tournament skimmed the outside edge of the hole and he was left to rue that miss in quite astonishing fashion.

They returned to the same hole for the playoff and Matsuyama, having gone for the 3-wood off the tee, elected to use the same club for his second shot from 277 yards away and could not have hit it any better, sending it to three feet for an eagle putt to secure his eighth PGA Tour title and his third in less than a year as Henley made bogey.

Waialae Country Club holds a special place in Japanese golf history, with it being the course where Isao Aoki became the first player from the country to win on the PGA Tour.

And Matsuyama was thrilled to replicate his achievement.

"I got on a roll, I'm glad it came out this way," said Matsuyama. "To follow him [Aoki] up, I'm over the moon."

Kevin Kisner and Seamus Power were Matsuyama and Henley's closest challengers, finishing in a tie for third, four strokes off the pace.

Russell Henley remains in the lead ahead of the final day of the Sony Open in Hawaii but 2021 Masters Championship winner Hideki Matsuyama surged into contention on Saturday.

Henley carded a three-under-round of 67 to maintain his lead after being three strokes ahead at the halfway mark at the Waialae Country Club.

Japanese 29-year-old Matsuyama, though, moved up the leaderboard into second spot, two shots behind Henley, with a seven-under-63 to be 16 under overall.

Henley leads at 18 under, with Matsuyama 16 under, before four players are tied at 14 under in third in Adam Svensson, Seamus Power, Matt Kuchar and Haotong Li.

The American, who won the Sony Open in 2013, had two bogeys and five birdies in his round, including a 16-foot birdie putt on the 17th hole to buffer his lead after Matsuyama made his move earlier in the day.

Matsuyama, who carded rounds of 66 and 65 on the first two days, improved with a day-three 63 headlined by four birdies in his final seven holes.

Svensson and Power both hit five-under-rounds of 65 to remain in contention, while Kuchar and Li are close but carded rounds of three-under and two-under to fail to close on Henley.

American Russell Henley holds a three-stroke lead at the halfway mark of the Sony Open in Hawaii after a seven-under-63 on Friday.

Henley, who won the Sony Open in 2013, carded an eight-under-62 on the opening day and backed that up to be 15-under and three shots ahead of second-placed Haotong Li.

Li along with third-placed Matt Kuchar and equal fourth Chris Kirk all carded rounds of five-under-65.

Kirk is one of 10 players tied for fourth alongside Seamus Power, Stewart Cink, Corey Conners, Adam Svensson, Keita Nakajima, Davis Riley, Dylan Wu, Brandt Snedeker, Payton Kizzire and 2021 Masters winner Hideki Matsuyama.

Henley's seven-under-63 was a round-best alongside Cink and Charles Howell III who both surged up the leaderboard.

The 32-year-old American had an even card on the second round before holing a bunker shot for eagle on the 18th hole, his ninth hole of the day.

Henley came home strong with four birdies and an eagle in his final six holes, including a 29-foot eagle putt. He has three PGA Tour titles across his career, the last being in 2017.

Veteran Jim Furyk dropped well off the pace after his fast start, with a two-over-round of 72 leaving him six under at halfway, while day one leader Kevin Na slipped to eight under after a round of one-over-71.

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.

Australian Cameron Smith holds a one-stroke lead after the opening day of the PGA Tour's calendar year-opening Tournament of Champions in Hawaii on Thursday.

Smith carded an eight-under-par 65 which included two eagles along with five birdies and one bogey to claim the lead ahead of three players including world number one Jon Rahm on seven under.

Rahm is tied with American pair Daniel Berger and Patrick Cantlay following rounds of 66 in good conditions.

More than half of the 38-player field broke 70 in the conditions, although Grand Slam winners Phil Mickelson, Jordan Spieth (both 71) and Justin Thomas (74) were not among that group.

Top-ranked Rahm and PGA Tour Player of the Year Cantlay were both returning to competitive golf after several months off and made fine transitions.

The Spaniard had seven birdies and no bogeys in his round, while Cantlay started with a bogey but finished in style, with four birdies and an eagle in his final five holes.

Berger might have shared the lead with Smith if not for a bogey on the penultimate hole, having made five birdies on his front nine.

Erik van Rooyen, Kevin Na and Sungjae Jim are six under, while world number two Collin Morikawa and four-time major winner Brooks Koepka are among five players at five under.

Top 20 trio Bryson DeChambeau, Xander Schauffele and Hideki Matsuyama are also not far off the pace after opening rounds of four-under for 69.
