Adam Hadwin ended Thursday as the outright leader following the opening round of the U.S. Open in Brookline, Massachusetts.

The Canadian shot a four-under-par round of 66, one ahead of five players tied for second, including Rory McIlroy, who had been four under himself before bogeying his final hole on the ninth.

Callum Tarren, David Lingmerth, Joel Dahmen and M.J. Daffue sit alongside McIlroy, with seven more players on two under, including Justin Rose and Dustin Johnson.

It was otherwise not a great day for some of the LIV Golf International Series participants, with Phil Mickelson carding an opening round of 78 (seven over), while Louis Oosthuizen managed just one shot better and Sergio Garcia finished on four over.

LIV Golf's new additions Patrick Reed and Bryson DeChambeau ended even par and one over respectively. 

World number one Scottie Scheffler recovered from a wobbly start to finish on even par, while PGA Championship winner Justin Thomas ended the day one under, as did the man he beat in a playoff for that trophy, Will Zalatoris.

Defending champion Jon Rahm, Collin Morikawa and Adam Scott also shot one-under rounds of 69, while world number four Patrick Cantlay came away from Thursday two over.

Shot of the day

After ending up just off the green in the longer grass on the 12th, a precision chip from Matt Fitzpatrick still had a significant distance to travel, but slowly rolled its way straight into the hole to the delight of the Englishman and the Brookline crowd, sending him back to two-under straight after bogeying the 11th.

Player of the day - Adam Hadwin

Hadwin sat on one over after three holes, before birdieing five of the next six to catapult himself into the leading pack. The 34-year-old has never finished higher than T39th in this tournament, and also responded to a bogey at 12 with another immediate birdie at 13, and then ended with five tidy pars to head into day two as the outright leader.

Chipping in

Rory McIlroy: "I'm going into tomorrow with the mindset of 'let's keep it going', rather than 'where is the cut line' or whatever. If you don't get off to a great start, those thoughts start to creep in, 'okay, what do I need to just be here for the weekend?'"

Jon Rahm (asked about two children stealing his ball on the 18th hole): "Yes… I'm pretty sure I know who it was. I recognised the two kids that were running the opposite way with a smile on their face. (Laughing) I am 100 per cent sure I saw the two kids that stole it."

A little birdie told me...

- McIlroy's 67 was the 13th of his career at the U.S. Open, now level with Seve Ballesteros and Sergio Garcia for most by a European player at the tournament.

- Lingmerth, ranked 592nd in the world, has never finished worse than tied for 21st in three previous U.S. Open appearances, and the Swede started with a promising 67 here.

- The first round scoring average of the last 10 winners at the U.S. Open is 69.1, with 25 players hitting under that on Thursday.

Rory McIlroy said he is in a "good spot" mentally after making a strong start to his quest for U.S. Open glory.

The four-time major winner headed to Brookline on the back of a superb victory at the Canadian Open last weekend and opened up with a three-under-par 67, a score that was enough for the co-lead when he finished his round.

McIlroy made a bogey on his final hole to put a slight dampener on things, but the Northern Irishman feels in good spirits as he bids to end an eight-year wait for a major trophy.

"I think [winning the Canadian Open gave me] comfort, more than anything else," said McIlroy, whose triumph in Canada was his 21st on the PGA Tour.

"Knowing my game is in good shape, knowing that when I had to answer the call, make some birdies or do something, I was able to.

"I feel like playing 72 holes in a U.S. Open is playing under pressure the entire time, even though the tournament doesn't really start until the weekend.

"But yeah, [it gave me] comfort with my game, mentally I think I'm in a good spot, and I showed that out there today, just trying to keep myself going.

"Overall, my wedge play was pretty good, I gave myself plenty of chances. Really nice at 17. It was a little skip up the hill, I could see it pitch into the hill and zip back down the green. I hit the putt at seven a little firm, but it was nice after a couple of par saves to see another birdie go in."

Also among the early finishers was defending champion Jon Rahm, who sank a 21-yard putt for birdie on the 18th, ensuring he finished his first round with a one-under 69.

Having endured a frustrating back nine, Rahm spoke of his relief at seeing one drop.

"I played a really good first eight holes besides the bogey on three," he said. "I played really, really solid, and then the wind picked up and it was a bit of a struggle, so to finish with that birdie makes me really confident and it's a really good way to start.

"I didn't see anything go in all day, and to see that one curl in after a wayward tee shot, I got a little lucky, got a great drop and I was able to make that birdie, it's a good feeling to finish like that.

"It got a little difficult out there, I hit a lot of bad iron shots [on] the last 10 holes, so to make that putt felt really good."

The season's third major begins on Thursday in Brookline, Massachusetts as the U.S. Open gets under way at The Country Club.

There will be a strange feeling at the tournament with it being the first major since the controversial LIV Golf International Series began.

The USGA has confirmed that players involved in the Saudi-backed breakaway who qualified for the U.S. Open will still be allowed to compete, despite the PGA Tour taking a harder stance and suspending those who played in last week's inaugural LIV Golf event in London.

That means the likes of Phil Mickelson, Dustin Johnson and Sergio Garcia will be present in Brookline.

Tiger Woods will not participate due to fitness concerns, but there are plenty of other potential candidates to go for victory at The Country Club, such as world number one Scottie Scheffler and defending champion Jon Rahm.

Stats Perform's experts have taken a look at who they believe could succeed.

RORY'S THE STORY AND HE'S PRIMED FOR MORE GLORY – Russell Greaves

Rory McIlroy has set the standards on and off the course in recent weeks, his win at the Canadian Open coming after he had pledged his allegiance to the PGA Tour in the midst of the inaugural LIV Golf event. That was the Northern Irishman's 21st PGA Tour title, fittingly edging him ahead of LIV Golf CEO Greg Norman, a fact McIlroy himself was quick to point out. In Massachusetts, McIlroy can distinguish himself even further from the likes of two-time major winner Norman as he seeks a fifth such title and second at this event. With accuracy off the tee likely to yield a premium on this course, McIlroy has the game to match his momentum and will doubtless be well backed by punters and fans alike. Sunday also marks 11 years to the day since McIlroy won the U.S. Open, collecting his first major success in the process.

DJ READY TO PLAY THE VILLAIN – Ben Spratt

Sure, Rory's return to the winners' circle at a major would be great, but that story surely pales next to the possibility of one of the LIV Golf rebels swooping in and taking the title. Johnson likely remains the breakaway league's best bet. Of course, he would not be a popular winner in front of a presumably vociferous Boston crowd, and the form book is not in his favour either, but Johnson has the talent to spoil the party; a U.S. Open victory in 2016 was the third of three straight top-five finishes – and it was only 18 months ago he was dominating the Masters. The 37-year-old has not won any event this year, in what stands as a career first, but this would be some time to end that drought.

RAHM READY TO MAKE HISTORY AFTER PLEDGING PGA LOYALTY – Patric Ridge

"I've never really played the game of golf for monetary reasons. I play for the love of the game, and I want to play against the best in the world. I've always been interested in history and legacy, and right now the PGA Tour has that." Those were the words of world number two Rahm, who is out to defend his title this week. Rahm finished T23 on his first appearance at the U.S. Open as a low amateur back in 2016, before he failed to make the cut in the next two years. However, he was tied for third in 2019 and T23 in 2020 prior to clinching his first major crown last year, finishing with two birdies on the final two holes to become the first Spanish golfer to win the major. The 27-year-old ranks first on the PGA Tour for shots gained off-the-tee, and although he struggled at the US PGA Championship, he has the opportunity to make history and create the legacy he dreams of in Massachusetts.

ROSE CAN BE A THORN IN RIVALS' SIDE – Peter Hanson

On the face of it, tipping a player ranked 48th in the world without a win to his name since January 2019 (Farmers Insurance Open) looks a little right field. At the time of that triumph, Justin Rose was world number one, but it has been a pretty mixed bag since then. Momentum is king in golf, though, and the Englishman scored a tie for fourth at the Canadian Open last weekend after shooting a sensational 10-under-par 60 in round four. Moreover, to win a U.S. Open you have to fight and scramble for a good score – qualities Rose, the 2013 champion, certainly possesses.

THOMAS HAS THE ENGINE NOT TO TANK – David Segar

Having won the PGA Championship at Southern Hills Country Club in May, Justin Thomas comes into this full of confidence and with good reason. He showed incredible fight to edge victory against Will Zalatoris in a play-off in Tulsa, having trailed by eight shots with 10 holes to play in the final round. Ranked fifth in the world, Thomas has always had the talent but, like many, it was always a question of putting it all together when the majors came around. With the experience of doing so fresh in his mind, and showing good form with third place at the Canadian Open, Thomas could pull off the rare feat of back-to-back major wins.

Jon Rahm says he is unsurprised by the amount of big-name golfers participating in the LIV Golf series given the financial rewards on offer, but sees more "meaning" in competing for historic prizes on the PGA Tour.

The Saudi-backed LIV Golf series, which held its first event in London last weekend with victor Charl Schwartzel pocketing $4.75million as the inaugural winner, has attracted several the game's biggest names by offering eye-watering prize sums.

The likes of Bryson DeChambeau, Phil Mickelson, Dustin Johnson and Sergio Garcia are among those to have signed up to the new circuit, with players participating in the first LIV event having been suspended by the PGA Tour last week.

Other stars, including Rory McIlroy, have made their opposition to the new tour clear, with the four-time major winner claiming on Tuesday it will "fracture" the sport.

And while world number two Rahm respects other players' decisions to feature in the breakaway competition, he simply does not see the appeal.

Speaking ahead of the U.S. Open, defending champion Rahm explained that he sees more "meaning" in competing with the world's best players in historic competitions on the PGA Tour.

"I mean, hundreds of millions of dollars are a pretty good damn reason for people to decide and go, and I see a lot of comments that's regarding it, but the high majority of the population, if they offered you 100 million or more for the next four years, a lot of people would go, right?" he said. 

"I'm not surprised at the number of players that went. I do see the appeal that other people see towards LIV Golf.

"[But] to be honest, part of the format is not really appealing to me. I want to play against the best in the world in a format that's been going on for hundreds of years. 

"There's meaning when you win the Memorial Championship. There's meaning when you win Arnold Palmer's event at Bay Hill. There's a meaning when you win, [at] LA, Torrey, some of the historic venues. That to me matters a lot.

"My heart is with the PGA Tour. That's all I can say. It's not my business or my character to judge anybody who thinks otherwise."

Rahm also added that the financial rewards on offer on the new tour – headed up by chief executive Greg Norman – would not change his mind.

"Truth be told, I could retire right now with what I've made and live a very happy life and not play golf again," the 27-year-old said. 

"I've never really played the game of golf for monetary reasons. I play for the love of the game, and I want to play against the best in the world. I've always been interested in history and legacy, and right now the PGA Tour has that."

Rahm's compatriot Garcia, meanwhile, joined Johnson in resigning his membership of the PGA Tour last month.

While Rahm says Garcia's decision is none of his concern, he hopes the split will not impact players' chances of competing at the Ryder Cup.

"[It's] not my business," he added. "He has given golf, [the] European Tour and the PGA Tour 20, 25 years of his life. It's his decision. It's not my job to judge. 

"That's all I can say. I don't know what's going to happen. I think the one thing that keeps coming to me out of all this and what can happen… I hope the Ryder Cup doesn't suffer.

"Are they going to be able to play Ryder Cup or not, the players that went? In my mind, Sergio, even if he is not breaking 90, he's a no-brainer pick, right? So what's going to happen? 

"You have quite a few young Americans. Bryson went, somebody that's probably going to be on the team in the future. 

"I think a week like that is a true essence of the game. That's where we all love to play."

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.

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.

Justin Thomas ultimately prevailed in a thrilling US PGA Championship, lifting the Wanamaker Trophy after Mito Pereira's collapse on the 18th hole forced a playoff.

Holding the lead coming into the final round, Pereira only needed a par on the 18th hole to secure his first PGA Tour victory, but put his drive in the water and could not even salvage a bogey to earn his spot in the playoff.

With a double-bogey capping off a final round 75, he went from six under to four under, tying for third with Cameron Young.

The playoff was contested between Thomas and Will Zalatoris after both players produced clutch shots late in their rounds to finish at five under.

Thomas – who tied for the round of the day with his 67 – had a birdie putt on 18 to move to six under, but could not convert from 10 feet, finishing with a par to head into the clubhouse in outright second place, trailing Pereira by one shot.

Zalatoris, on the other hand, bogeyed the 16th to drop to four under, but came right back with a birdie on 17. He had a tricky par putt on 18 to remain tied with Thomas, and he remained cool under pressure.

In the playoff – which was contested over the aggregate score of three holes, the first being a par-five – Zalatoris appeared to strike first as he found the fairway with his drive, while Thomas hit the rough. Thomas was forced to lay-up, while Zalatoris made the green in two.

Zalatoris two-putted for his birdie, while Thomas put his wedge to within six feet, converting his birdie putt to tie the first playoff hole.

The second playoff hole was the 17th – a drivable par-four – and Thomas found the green with his drive. Zalatoris did not, and after chipping into birdie range, he missed his putt, tapping in for par. Thomas, on the other hand, safely two-putted for birdie to take a one stroke lead into the final playoff hole.

Both players drove well and made the green in regulation on the last, and after Zalatoris failed to sink a long birdie putt, Thomas only needed to two-putt for par to secure his second career major, making no mistakes. It is his second PGA Championship, five years after winning at Quail Hollow.

Also making the top-five was the English duo of Matt Fitzpatrick and Tommy Fleetwood – with the latter matching Sunday's best score – and American Chris Kirk, tied for fifth at three under.

It was a strong final round from Rory McIlroy, who rebounded from a disappointing 74 on Saturday to shoot 68 – one stroke off the round of the day – to finish outright eighth at two under.

McIlroy looked like he may be trending for a legendary final round after four consecutive birdies starting on the second hole, but he would claim no more from the fifth.

A four-man group of Mexico's Abraham Ancer, Ireland's Seamus Power and the American pairing of Tom Hoge and Brendan Steele rounded out the top-10, and the last players to finish under par.

Cameron Smith and Xander Schauffele highlighted the group at even par, while the big names struggled, as Jordan Spieth finished at four over, Jon Rahm wrapped up at six over, and Collin Morikawa at eight over.

Shot of the day

The shot of the day went to Englishman Laurie Canter, who birdied the difficult par-four 18th hole from the fairway.

After his drive found the rough, he was forced to lay-up 97 yards from the pin, but was able to convert it thanks to some sharp backspin.

A little birdie told me…

Before his horror drive on 18, Pereira earned his 71-hole lead with great success on the difficult par-fives and par-threes. He joined Webb Simpson as the only players to shoot a combined six under on the par-fives (fifth and 13th holes) over their four rounds

Only four players finished under par for the week on the par-threes (sixth, eighth, 11th and 14th holes) – Fitzpatrick and Rose were two under, while Pereira and Steele shot one under.

On average, nobody drove the ball further than Rory McIlroy this week, posting 347.6 yards per drive. However, the longest drive of the week went to Jon Rahm, with a 418-yard bomb.

Jon Rahm said "everything was difficult" on day two at the US PGA Championship, but matters could hardly have been more different for Justin Thomas.

Rahm, one of the pre-tournament favourites, endured a difficult opening round at Southern Hills Country Club but the Spaniard responded with a respectable, one under par 69 on Friday.

That leaves the world number two on two over par, which should just see him sneak over the cut line. Former world number one Dustin Johnson, meanwhile, is unlikely to be so fortunate, having carded a second successive 73.

Rahm conceded that he has found it tough going so far, though he was nevertheless happy with his second round.

"I can't say I played bad. I gave myself a lot of chances," said Rahm, who balanced out two bogeys with three birdies.

"I think the main thing yesterday was a couple of mistakes, just mental mistakes. There was three; one on eight, skulling that chip. Should have made something better than a six on 13 with a five-iron in my hands. And putting it on dry land on 17.

"Those are three shots that I could have done better and I could be at one under right now, and that was just strictly mental.

"Today I can't ask much more of myself. It was a good day, it was good golf. Just tough. And I played really good to show one under."

One player thriving in the tough conditions in Oklahoma is Thomas, who took the lead off Rory McIlroy with another round of 67, replicating his score from Thursday.

Thomas' sole major triumph so far came at the US PGA Championship in 2017, and the American looks well-placed to push on after heading into the clubhouse on six under through his two rounds, putting the pressure right back on overnight leader McIlroy, who bogeyed his second hole on Friday to drop two shots off the new leader.

"Very pleased. I felt I played, although I played solid yesterday, I played really, really well today," said Thomas.

"The conditions were obviously very difficult. I stayed very patient, tried to get in my own little world and get in a zone and just tried to execute each shot the best I could.

"I felt we did a great job of that and am glad to have a good round to show for it."

Thomas only slipped up once, on the 14th, but made four birdies, but the 29-year-old is wary not to get ahead of himself.

"I like this golf course. I feel like I'm playing well," he continued. "We're halfway through so it's still a long way from home, but I'm very, very pleased with where everything is at and the frame of mind and state of mind that I'm in.

"Just need to try to maintain that the best that I can and keep trying to play good golf."

Phil Mickelson's legacy has not been ruined by his contentious comments regarding the LIV Golf Invitational, according to Jon Rahm.

Mickelson has not played since February after he was criticised for comments about the Saudi Arabian-backed breakaway competition, which holds its first event in London next month.

The 51-year-old apologised for those comments and decided to take a break from golf, though he was one of a number of high-profile players to then request a release from the PGA Tour for the inaugural LIV event at the Centurion Club from June 9 to 11.

Mickelson's representatives confirmed at the time that he had not definitively decided on playing in the tournament, or indeed the US PGA Championship, which tees off on Thursday in Tulsa.

The American is the reigning champion, having become the oldest player to win a major when he triumphed at Kiawah Island in 2021, but last week the tournament organisers confirmed he had withdrawn.

While Mickelson's withdrawal may well boost the chances of Rahm winning at Southern Hills Country Club, the world number two is sad not to see one of golf's biggest stars at the event.

However, he believes six-time major winner Mickelson should be able to return to the PGA Tour when he sees fit.

Rahm told Sky Sports: "He's given his life to the sport. Nobody has been better to the fans over a 30-year span and nobody has done more for the Tour than he has, right.

"Obviously Tiger [Woods] took his game to many places, but Phil won over 40 events and six majors.

"That characteristic smile and thumbs up are synonymous with Phil Mickelson. It's a name that is known worldwide.

"I don't think that a couple comments at the wrong time should dictate the legacy of a man.

"If anything, we're in America, the land of opportunity, right? If there's a place where things can be forgiven, and you can get back to where you need to be, it's here. I think given time and the proper course of action, that can happen."

That being said, Rahm understands that Mickelson ultimately brought the criticism on himself.

"He said what he said, he brought it on himself, so it needs to come from him to take it back to where it should be," Rahm added.

Golf's world number two, Jon Rahm, believes teenage compatriot Carlos Alcaraz can benefit from having Rafael Nadal around as his burgeoning tennis career progresses.

Nineteen-year-old Spaniard Alcaraz became the first tennis player to beat both Nadal and Novak Djokovic in the same tournament on clay, on his way to becoming the youngest ever winner at the Madrid Open earlier in May.

Alcaraz has won three of the past four tournaments he has entered, including the Miami Open, moving to number six in the ATP world rankings and emerging as a serious challenger for the French Open, which starts on Sunday.

When asked about Alcaraz's rapid ascent, Rahm said Alcaraz can still learn a lot from 21-time grand slam winner Nadal.

"I thought you were talking about a golfer. I was just confused," Rahm joked, speaking ahead of this week's US PGA Championship. "I've heard about what he's done, and I've seen the results. Pretty impressive, especially in the world of tennis.

"He's got some big shoes to fill, because historically Spain has had great tennis players, and obviously with Rafa out there it can be probably daunting yet really exciting too for somebody like him.

"You have a great reference who's done it right in front of you, so I'm sure he can pick his brain and learn. He's got a great start. Hopefully he can keep it going and be a great champion like many others have been."

Following a tie for 27th at the Masters, Rahm returned to action earlier in May, winning the Mexico Open.

The lingering dynamic this weekend at Southern Hills will be the fact Phil Mickelson will not be there to defend his title, following his controversial remarks about the Saudi-backed breakaway golf tour.

Rahm and Mickelson share the same alma mater and agency, and the former continued to defend the six-time major winner.

"Phil has got to do what Phil has got to do," Rahm said. "He's a good friend of mine. I can't remember the last time a major champion didn't defend a title.

"But he's got to do what's best for him. That's all I can say. I can't say it makes me unhappy. As long as he's doing what is best for him, I can't truly say I'm unhappy.

"I would have liked to see him defend. I know he's played good here in the past. But again, he's got to do what he's got to do."

The season's second major gets under way on Thursday, as the US PGA Championship starts at Southern Hills Country Club.

Despite being included in the field for the tournament in Tulsa, Oklahoma, reigning champion Phil Mickelson will not be on hand to defend his title.

Mickelson, who became the oldest player to win a major when he triumphed at the US PGA in South Carolina last year, is continuing his break from golf, which came after criticism over his comments regarding the Saudi Arabia-backed breakaway Golf Super League.

While the GSL cloud hangs over the heads of certain players who have requested releases from the PGA Tour, the focus this week will be on claiming the huge prize of a major title.

Tiger Woods is back, after his remarkable Masters return, while world number one Scottie Scheffler is on the hunt for another major title following his success at Augusta.

Stats Perform's experts have taken a look at some of the likely candidates.

No stopping Scottie – Ben Spratt

Only three men have won both the Masters and the US PGA in the same year, with Jack Nicklaus the last to do so in 1975. That is the esteemed company Augusta champion Scheffler hopes to be keeping – and you would be bold to back against him this season. Scheffler ended 2021 ranked 12th in the world and still waiting on his first PGA Tour victory. He has since won four times, including at the Masters, to become world number one and the clear man to beat. The 25-year-old has two top-10 finishes in both entries at this tournament and played a practice round at Southern Hills earlier this month to prepare himself for another tilt.

Rahm makes timely return to form – Patric Ridge

World number two Jon Rahm will tee off in Oklahoma on Thursday on the back of winning the Mexico Open last time out. Rahm has finished in the top 15 in six of the 11 competitions he has featured in this season. Prior to his win in Mexico, the Spaniard's putting had been letting him down, but the rest of his game has been top-notch. Rahm's strokes gained off the tee is a PGA Tour-leading 1.311, while his strokes gained tee to green also ranks first (1.808). The 27-year-old finished T8 in this major last year and his best result was T4 back in 2018 – he could be celebrating back-to-back wins on Sunday.

First major to get Burns treatment – John Skilbeck

Sam Burns missed the cut at the AT&T Byron Nelson, but we should forget that; one bad round cost him and there have been very few of those this season from the 25-year-old. Besides, he followed that 73 with a gutsy 67. Admittedly, Burns also missed the cut at the Masters, but he has titles at the Sanderson Farms Championship and the Valspar Championship in the current campaign, successfully defending his title at the latter after a breakthrough win last year. He has achieved six top-10 finishes in the 2021-22 season, has banked almost $4.5million, and sits second in the FedEx Cup standings. The PGA Championship can throw up funky winners and Burns might just be ready to join the list. He has yet to challenge in a major but that surely must change soon.

Rory can end major drought – David Segar

It is eight years since Rory McIlroy won the last of his four majors at the PGA Championship, but the Northern Irishman can end that drought this week. He produced a late surge to finish second in The Masters, with a stunning Sunday 64. McIlroy is third on the PGA Tour for shots gained off the tee. His two scores of 68 over the weekend earned fifth place at the recent Wells Fargo Championship, setting him up nicely for another major challenge.

Spieth slam? Oh, it's on… – Pete Hanson

Is this the week Jordan Spieth completes the Grand Slam? A tie for 71st and 30th in his last couple of attempts don't make for particularly good omens but Spieth is a player reborn. Having slipped as low as 92nd in the Official World Golf Rankings after last year's Farmers Insurance Open, Spieth has gone about climbing back into the world's top 10 and was back among the winners' circle at the RBC Heritage last month. A missed cut at the Masters was not the start he envisaged to major season but Spieth is at his best with his back against the wall and can firmly be in contention to lift the Wanamaker Trophy come Sunday.

Jon Rahm said his Sunday round with Tiger Woods at the Masters hammered home the lessons he needed to win the Mexico Open.

World number two Rahm shot all four rounds in the 60s, holding on down the stretch at 17 under to win by one stroke ahead of the fast-finishing duo of Tony Finau and Brandon Wu, who both shot 63 on Sunday.

The win was the Spaniard's first since the 2021 U.S. Open, with second place in January's Sentry Tournament of Champions and a tie for third in the Farmers Insurance Open his best results this season.

Speaking to the media after his triumph, Rahm highlighted lessons he took from playing his final round at Augusta National last month with Woods, who made a remarkable turn to elite-level golf at the major.

"I think that Sunday with Tiger at Augusta gave me quite a bit of confidence," Rahm told a news conference. "I was a little bit technical in my approach – a little too technical. 

"I'm a feel player, and that Sunday I told myself 'just go out there and hit the golf ball'. Make shots, make the swings you want to make, see the ball flight and execute. 

"I shot a three under, not having my best stuff, on a tough day, so I applied the same thing this week."

Rahm also touched on his desire to have a win at Vidanta, after a number of close calls at Chapultepec for the WGC-Mexico Championship, and how the game has grown in the country.

"I was close to winning at Chapultapec a couple times – I had a chance – but I didn't quite get it done," he said. "I knew I could get it done. I came this week wanting to [get a win in Mexico]. 

"I've spoken at length about the importance of Seve [Ballesteros] and his impact on the game of golf and how I play because of him. 

"Nowadays we have a much bigger reach, the PGA Tour has become a bigger tour, and with social media, we're worldwide stars, bigger than they were in the past. 

"I feel like I can make some impact in Mexico as well, and Mexico deserves a good event. You can even see golf growing in Mexico as well.  It's a true honour to be able to come here in this first edition of the event to be the champion."

World number two Jon Rahm scored a two-under 69 on Sunday to hold on for a one-shot victory at the Mexico Open.

Rahm's last win came at the US Open in 2021 at Torrey Pines, and it showed as the 27-year-old pumped his fist after holing his par putt on the 18th at the Vidanta course.

There was a sense of relief for the Spaniard, with only one tournament win out of seven times on the PGA Tour where he came into the final day with at least a share of the lead.

With scores of 64, 66, 68 and 69 over the four days, Rahm kept it steady after setting the initial marker after 18 holes, but he still had to deliver when it counted.

After bogeying the par-four 10th for the third consecutive day, there was a four-way tie for the lead as Rahm came to the 14th hole.

He eventually birdied for the third consecutive day on the 14th, despite leaving himself with a tricky left-to-right putt for the up-and-down.

Not dropping a shot for the rest of round, Rahm finished a stroke clear on 17-under for the tournament, ahead of Kurt Kitayama, as well as the fast-finishing Tony Finau and Brandon Wu.

Finau and Wu both posted scores of 63 on the final day in Vidanta, both scoring eagles on respective par fives on the 14th and sixth holes.

Finau's last win came in a playoff against Cameron Smith at The Northern Trust in 2021, and after going five-under from the final six holes, it seemed like another playoff could be on the cards.

Rahm kept his nerve however, and held on for his seventh tournament win on the PGA Tour.

In doing so, he overtook Jose Maria Olazabal (six) for the third-most Tour wins by a Spaniard.
