Brooks Koepka was pleased with his first round at the U.S. Open, while in-form Phil Mickelson was in an optimistic frame of mind despite struggling in San Diego.

On an interrupted opening day due to fog and weather at Torrey Pines, two-time U.S. Open champion Koepka finished two strokes behind co-leaders Russell Henley and Louis Oosthuizen (through 16) as play was suspended because of darkness on Thursday.

American star Koepka – chasing his fifth major title – set the standard with four birdies in his first 11 holes taking him into a solo lead.

However, two bogeys meant he had to scramble to recover as Koepka ended the day alongside Xander Schauffele, Hayden Buckley, Masters champion Hideki Matsuyama, John Rahm (through 17) and Sebastian Munoz (through 14).

Koepka, who has gone on to win or finish second in six of the last 10 majors which he opened with a score in the 60s, said: "You can't win it today but you can definitely lose it. It was nice to get off to a good start, putted well, drove it well on the back nine, my front, but missed a couple fairways there.

"I missed them on the correct side, which is what you've got to do, depending on where the pin location is and get lucky enough where you've got a decent lie and get it there.

"Pretty pleased. Not the best, but I'll definitely take it."

US PGA Championship winner Mickelson is already facing an uphill task following his four-over-par 75.

Mickelson, who became the oldest major winner when he clinched the PGA Championship ahead of Koepka last month, finished with five bogeys, including back-to-back on the front nine.

"It was a great set up and I had some chances to get the round a little bit better," Mickelson said. "Fought hard, made a lot of short putts to kind of keep myself in it and then I ended up bogeying six and seven.

"Two over would have been a pretty good round and I ended up at four, so I'm a little disappointed about that. I feel like I'm close to putting together a good round."

South African veteran Oosthuizen – through 16 holes – moved into a tie at four under after birdieing the 14th.

Winner of the 2010 Open Championship, Oosthuizen is one of three players to finish in the top 10 at each of the last two U.S Opens.

"I just enjoy playing really tough golf courses. I think somehow I focus a little bit better when I play those courses, knowing that the margin for error is really small," said Oosthuizen.

"Especially around this place, you've got to drive it well, you've got to start it in the fairway, and you're going to have trouble if you're missing fairways around this golf course and I've really been driving it good lately."

Four-time major champion Rory McIlroy birdied his final hole to move within three shots of the lead heading into the second round.

"It was really nice. The birdie is awesome," McIlroy – who posted a 70 – said. "I mean, that putt was pretty, I was sort of like, I think it's straight, I'll hit it straight and we'll see. But it was nice to get in, get an extra hour of sleep tonight and it was a bonus to birdie in as well."

Louis Oosthuizen joined Russell Henley in a share of the lead as the opening round of the U.S. Open was interrupted, while Phil Mickelson's quest for back-to-back majors got off to an awful start at Torrey Pines.

A fog-enforced delay meant the start of the major tournament was pushed back by around an hour and a half on Thursday, and while Oosthuizen was unable to finish his round, the 2010 Open Championship winner still ended the day alongside Henley atop the leaderboard.

Oosthuizen – one of three players to finish in the top 10 at each of the last two U.S Opens, joining Rory McIlroy and Xander Schauffele – moved into a tie at four under after birdieing the 14th hole in San Diego.

Henley had set the early pace after claiming an early lead behind his impressive four-under-par 67, which was enough for him to initially head back to the clubhouse with a one-shot lead over Francesco Molinari and Rafa Cabrera Bello.

It was Henley's sixth career score of 67 or better in a major championship and first since the 2018 US PGA Championship (65 in round two).

Molinari and Cabrera Bello remain a stroke off the pace heading into Friday, with the first round scheduled to resume at 06:50 local time.

Two-time U.S. Open champion Brooks Koepka is not far behind following his two-under-par 69 to kick off his pursuit of a fifth major crown.

Koepka, who finished second behind Mickelson at the PGA Championship, set the standard with four birdies in his first 11 holes taking him into a solo lead.

However, two bogeys meant he had to scramble to recover as Koepka ended the day alongside Schauffele, Hayden Buckley, Masters champion Hideki Matsuyama, John Rahm (through 17) and Sebastian Munoz (through 14).

Koepka has gone on to win or finish second in six of the last 10 majors which he opened with a score in the 60s.

World number one Dustin Johnson and star Rory McIlroy were both through 17 holes when play was called for the day.

Johnson had mixed a birdie with a bogey, while four-time major champion and 2011 U.S. Open winner McIlroy had an eventful start with three bogeys and four birdies.

Defending champion Bryson DeChambeau and his bid for back-to-back trophies started with a two-over-par 73.

American star Mickelson ended the round two shots worse off than DeChambeau following his forgettable 75.

Mickelson, who became the oldest major winner when he clinched the US PGA Championship last month, finished with five bogeys, including back-to-back on the front nine.

The pursuit of major glory at the U.S. Open got underway after a fog-enforced delay on Thursday, with favourite Jon Rahm among a host of contenders primed for action at Torrey Pines.

As two groups went out after the fog had cleared at around 08:15 local time at the first and 10th holes, around an half and half later than planned, the big names were waiting in the wings, with Rahm hotly tipped for success.

Rahm, who suffered a coronavirus-enforced withdrawal when he led after three rounds at the Memorial Tournament this month, is scheduled to head out at 15:36.

The Spaniard has never won a major and has a best finish at the U.S. Open of third in 2019.

Reigning champion Bryson DeChambeau will begin his title defence at 15:14 in a group with Masters holder Hideki Matsuyama and Tyler Strafaci.

DeChambeau's rival Brooks Koepka, who won back-to-back U.S. Opens in 2017 and 2018, can attempt to apply some pressure when he goes out at 09:29 with Justin Thomas and last year's US PGA Championship winner Collin Morikawa.

The man who took that honour from Morikawa, Phil Mickelson, can complete the Grand Slam this week, and Lefty will tee off his bid to join that elite club at 09:51. He has been runner-up six times in this event.

Rory McIlroy, a winner in 2011, will seek to add a fifth major when he gets his tournament up and running at 15:36 alongside 2013 champion Justin Rose and world number one Dustin Johnson.

Tiger Woods began his U.S. Open bid with a double bogey in 2008 at Torrey Pines – "a terrible start", said the man who four days later took the title in a sudden-death play-off, after he and Rocco Mediate could not be separated in a two-man fifth round.

The 18-hole play-off scenario is now history, so there will no repeat of such a marathon effort as the major returns after 13 years to the San Diego course this week, and there will be no Woods either.

That 2008 triumph was a 14th major for the American, yet he had to wait another 11 years until the 15th arrived, the man who once seemed booked in to take the major titles record away from Jack Nicklaus having seen perceptions of his life switch from fairy tale to soap opera.

Woods in 2008 was privately fighting the pain of a double stress fracture of his left tibia that he kept under wraps. Yes, he won the U.S. Open with a broken leg.

Whoever lifts the trophy this Sunday is unlikely to have to overcome the tribulations that faced Woods across that long weekend, and the superstar's absence is sure to be felt ... until the first round begins to take shape and a new narrative plays out.

Back in 2008, tournament organisers upped the intrigue by grouping Woods, Phil Mickelson and Adam Scott – the world number one, two and three – together for the opening two rounds.

Local favourite Mickelson recalls the moment when Woods fluffed his opening hole.

"I thought that was pretty inspiring the way he didn't let that affect him," Mickelson said this week. "He stayed to his game plan, stayed focused, stayed patient, and ended up kind of picking his spots where he could get a shot back here or there, and he did, and he ended up winning. That's impressive."

After completing his opening round, Woods said his mindset after shooting six at the first was to "just be patient, long way to go", and he finished one over par.

By the end of day two, Woods stood tied for second place, with Mickelson and Scott in a group sharing 35th position.

"The atmosphere for the whole 36 holes that I played with Phil and Tiger was incredible," Scott recalled earlier this year. "But Thursday morning the energy around the first hole was like I can't compare it to anything else actually.

"It was not even like teeing off at the Masters or anything like that. The build-up ... Tiger obviously being Tiger and Phil, the local hero, one, two and three in the world, of course I was like the third wheel hanging off the back, but it was really fun to be a part of that."

Of course Woods is a once-a-generation talent, but should anyone make a similarly poor start this week, it would be wise to take the blow on the chin and move on.

This course, the long-time home of the annual Farmers Insurance Open, should reward a steady temperament.

Mickelson, fresh from his shock victory last month at the US PGA Championship, where he became the oldest winner of a major, described the Torrey Pines greens on Monday as "very challenging".

"There's a lot of pitch, a lot of contour, and as they get firmer, they're significantly firmer than just the last two days," he said.

"It's very difficult to get it to some of the pin positions, and it's going to be a difficult test. As long as it is at sea level it's going to be a difficult task, but it seems like the set-up is pristine, and it's going to be a fun, very difficult challenge."

WHO WILL WIN THIS TIME?

With Woods out of the picture, recovering from the car crash he was said to have been fortunate to survive in February, there will be no repeat of his famous success 13 years ago.

Woods has won the Farmers Insurance Open a record seven times too, so he would have been relishing this week. Brandt Snedeker and Jason Day are both two-time winners of that tournament, and Mickelson has been champion three times, but not since 2001.

Mickelson is seeking the trophy that would give him a career grand slam, but it seems fanciful to expect him to challenge, having rarely been a factor in the majors in recent years until his unexpected win at Kiawah Island.

Stats Perform has taken a combination of factors to build a list of potential contenders, assessing past performance at the Farmers Insurance Open but also weighting displays in majors and recent PGA Tour form.

These scores are built around performance at Torrey Pines from 2016 to this year.

In the calculations, top-10 finishers at the 2021 Farmers Insurance Open receive points on a scale from 15 for the champion down to six points for 10th place. This decreases on a year-by-year sliding scale to 10 points for the 2016 tournament winner and one point for 10th place in that event.

There is also two points awarded per top-10 finish on the PGA Tour in the 2021 season, and substantial points availability for recent major success (10 points per major title in 2020 and 2021, 8pts in 2019, 6pts in 2018, 4pts in 2017, 2pts in 2016).

Not all players in the U.S. Open field have played the Farmers Insurance Open each year, and some are rarely active, if at all, on the PGA Tour, but this may give an inkling of the players who could come into contention at the year's third major.

TONY FINAU, 52 points: Finau followed up three top-10 results at the Farmers (2017, 2018, 2020) by finishing a joint runner-up in 2021, pointing to a clear liking for the course. How he enjoys it later in the year than he usually encounters Torrey Pines remains to be seen. Finau also has seven top-10 finishes of tour in the 2021 season.

JON RAHM, 52 points: His first major title is arguably overdue, given his talent and week-by-week results. Rahm was Farmers champion in 2017 and runner-up in 2020, also finishing top 10 in 2019 and 2021. He has a tour-leading 10 top-10 finishes this season, and would surely have had a win at the Memorial Tournament earlier this month before a positive COVID-19 test ended his title charge after 54 holes.

PATRICK REED, 42pts: This year's champion at the Farmers Insurance Open, Reed was also top six there in 2020, has had six top-10 results on tour this season and landed a Masters title in his not-too-distant past.

RYAN PALMER, 33pts: Palmer tied for second earlier this year at Torrey Pines, just as he did in 2018. Those performances and his four top-10 finishes on tour this year make him perhaps the surprise name on this list.

BROOKS KOEPKA, 32pts: Koepka missed the cut this year at the Farmers and did the same in 2017, and he did not play the tournament in the intervening years. Although Koepka has little left to prove in a wider sense – his mountain of points here is accrued through past major wins and a healthy batch of top-10s this season – he has yet to master Torrey Pines. Koepka has also missed the cut at three of his most recent four tournaments this year.

RORY MCILROY, 31pts: Top-five finishes at the Farmers in 2019 and 2020 augur well for McIlroy, and his five top-10 finishes on tour this season is a tally he will aim to add to over the coming days. It may be asking a lot to expect him to carry off the title, but another high placing would seem realistic.

Next on the list: Justin Rose (30pts), Brandt Snedeker (29), Viktor Hovland (26), Xander Schauffele (26), Jason Day (25), Marc Leishman (25), Hideki Matsuyama (25) and Keegan Bradley (24).

Only five men have achieved golfing immortality by winning each of the four majors and completing the coveted Grand Slam.

Jack Nicklaus, Tiger Woods, Ben Hogan, Gary Player and Gene Sarazen stand alone among the pantheon of greats to have topped the leaderboard at The Open, the U.S. Open, the US PGA Championship and the Masters.

Arnold Palmer, Tom Watson and Walter Hagen are among the sport's legends to have accomplished three legs of the Slam – an impressive feat in itself.

Indeed, three active players are just one away and each is eyeing a different title. Rory McIlroy is missing a Masters, Jordan Spieth a PGA Championship and Phil Mickelson a U.S. Open.

For Mickelson, it is certainly not for want of trying – on six occasions he has finished second or tied second for a prize he so greatly craves.

It appeared as though his chances were waning as Father Time had seemingly caught up with a true great. But then, Mickelson upset all the odds to win a sixth career major and second PGA Championship at Kiawah Island last month at the age of 50, making him the oldest player to win a major tournament.

With renewed hope at finally claiming the missing piece of the puzzle, we assess the chances of Mickelson, Spieth and McIlroy in the race to complete the Grand Slam.

PHIL MICKELSON

In terms of a straight race, you could argue that 'Lefty' is in pole position merely because his opportunity is next up.

Moreover, Mickelson has history at Torrey Pines – hosting the U.S. Open for the second time having last done so in 2008 – a venue where he is a three-time winner, albeit the last of those was in 2001.

But that in itself is testament to Mickelson's astonishing longevity, and he made a mockery of suggestions his major-contending days were over at Kiawah Island.

Still, to mix it at that sort of level in the 50s (Mickelson turns 51 on Wednesday) on a regular basis is tough. Indeed, the unexpected triumph was his only top-10 finish on the PGA Tour this season, while he ranks down at 167th for scoring average.

While he does impressively still average over 300 yards off the tee (302.8), in terms of fairway accuracy Mickelson is down at 199th (51.16 per cent), and a putting average of 1.791 would need to be improved to contend.

All in all, you would be a fool to say Mickelson cannot complete the Slam but, speaking pragmatically, even accounting for his PGA Championship heroics, it will take a monumental effort to go back-to-back in the majors this weekend.

RORY MCILROY

A player of outrageous talent whose career in terms of majors has perhaps not quite hit the heights many tipped him to reach.

McIlroy has four to his name thus far, the last of which arrived at the 2014 US PGA Championship. At that stage, it appeared a question of how many he would win. 

It has been a decidedly mixed bag since at the majors, and there is no doubt winning a green jacket is a prize McIlroy would crave above all others in his career.

There have been plenty of close calls at Augusta, where he has six top-10 finishes, and that does not include the 2011 tournament where McIlroy led heading into the final round before enduring an excruciating Sunday that saw him finish way down in 15th.

Once upon a time it would have sounded unthinkable McIlroy would never win a Masters. It's not as clear cut now perhaps, but there are many opportunities left for a player still only 32 years of age.

McIlroy has endured inconsistent form this season, but was a recent winner at the Wells Fargo in a sign that things are slowly starting to click back into place.

His scoring average of 70.363 is the 31st best on the PGA Tour this season, while he ranks tied 14th for top-10 finishes (five).

Only Bryson DeChambeau averages longer off the tee than McIlroy's 318.6 yards but he is way down in 173rd for driving accuracy, while a putting average of 1.740 is something he will be keen to improve.

JORDAN SPIETH

One of the most pleasing aspects of recent months has been the resurgence of Spieth, who had slipped as low as 92nd in the world rankings having missed the cut at the Farmers Insurance Open earlier this year.

But eight top-10 finishes – including a win at the Valero Texas Open – has catapulted him back up to 23rd and many fancied him to complete the Slam at the PGA Championship.

Despite fleeting flashes of promise, Spieth could only finish down in 30th but crucially – much like McIlroy – time is on his side. Indeed, due to the early career success that has seen him become a three-time major victor, it is easy to forget he is only 27.

Prior to Mickelson's triumph last month, the smart money would have been on either McIlroy and Spieth to do the Slam first and perhaps it still is.

Indeed, Spieth probably remains a solid bet to deny Mickelson's own hopes this weekend. He is 21st for scoring average (70.178) and second only to Jon Rahm (10) for top-10 finishes with eight.

Not known as a particularly big hitter off the tee, Spieth is down at tied 83rd for driving distance (298.0) and 184th for driving accuracy but only nine players have a lower putting average than his 1.716.

VERDICT:

In terms of immediate chances then, yes, of course Mickelson has the edge. But logic suggests that it will need a monumental effort for him to repeat what he did at Kiawah Island at Torrey Pines. McIlroy and Spieth can, theoretically at least, continue to compete at the top for the best part of the next two decades. If they do, both have ample opportunity to secure the Grand Slam. As for who does it first…well given the Masters is closer than the PGA then let's go with McIlroy. Check again next April!

Rory McIlroy acknowledged there is still plenty of room for improvement in his game after finishing off his work at the US PGA Championship with a final round of 72.

The world number seven came into the tournament with many fancying him to challenge, victory at the Wells Fargo Championship earlier in May suggesting he was returning to form at just the right time.

However, an opening 75 left him with work to do and he was never able to get into contention at Kiawah Island. A bogey at the 18th hole on Sunday saw him end on five over par, meaning the wait for a fifth major goes on.

For McIlroy, the key focus moving forward is finding greater consistency with his driver, having felt it has not been right "for a long time".

Asked to sum up his play on Sunday, he replied: "More of the same, very average.

"I couldn't really get anything going and it was a day where you had to get off to a fast start. The first few holes were playing a lot easier than they have done and I didn't do that, just sort of got stuck in neutral.

"I still have a way to go with everything. I just need to figure out a driver, as well. I just haven't driven the ball as well as I know that I can for a long time, and that's really the foundation of my game."

McIlroy won the US PGA Championship at the same venue in 2012, leading plenty to tip him to produce a repeat result nine years later, particularly coming after his recent success at Quail Hollow.

The man himself, however, was baffled at his status as favourite prior to the tournament, with his game "exposed" by the tricky conditions at the Ocean Course.

"I didn't understand those high expectations," he said. "It was good to win at Quail Hollow, a course that I've always played well on and am comfortable on.

"I didn't feel like playing well here nine years ago was going to automatically make me play well again, and I felt like coming in here there was still parts of my game that I needed to sharpen up, and obviously those parts were exposed this week in the wind and on a tough course."

Phil Mickelson and Louis Oosthuizen topped a leaderboard filled with major winners at the US PGA Championship, setting up a fascinating weekend at the Ocean Course at Kiawah Island. 

Mickelson started early and roared to the finish, carding five birdies on the back nine on the way to a 69 that left him at five under par for the tournament before Oosthuizen shot 68 in the afternoon for a share of the overall lead. 

Two-time US PGA winner Brooks Koepka (71) was one stroke back after recording a pair of eagles on Friday, followed by 2021 Masters champion Hideki Matsuyama (68) at three under. 

Oosthuizen's fellow South Africans Branden Grace (71) and Christiaan Bezuidenhout (70) also were two back of the leaders. 

First-round leader Corey Conners (75) and 2019 U.S. Open winner Gary Woodland (72) were at two under, with reigning U.S. open champion Bryson DeChambeau (71) dropping back to one under after a bogey on 18. 

Players battled windy conditions throughout the day and had an especially difficult time with the last two holes.

Oosthuizen lost his chance to stand alone atop the leaderboard with a bogey on 18 that ensured no one would post a bogey-free round on the first two days of competition, while Grace dropped three strokes on 17 and 18 to mar an otherwise stellar round.

Rory McIlroy (72) saw a move for contention disintegrate with bogeys on the final three holes that left him eight back of the leaders entering Saturday, and Jordan Spieth (75) was in the same spot after bogeys at 17 and 18.

The four-time major champion Koepka had perhaps the most erratic day of any contender, carding just one birdie to go with his eagles at the seventh and 11th and four bogeys. 

Among the notables missing the five-over cut line by one stroke were Dustin Johnson (74), Sergio Garcia (73), Adam Scott (72) and Justin Thomas.

Former major winners also missing out on the weekend include Zach Johnson (78), Jason Dufner (81), Martin Kaymer (77), Rich Beem (77), Charl Schwartzel (79) and John Daly (86). 

The 2009 US PGA Championship winner, Y.E. Yang, was disqualified after signing an incorrect scorecard but would have missed the cut anyway. 

Corey Conners withstood hammering winds to claim a two-stroke lead following the opening round at the US PGA Championship as Brooks Koepka impressed but Rory McIlroy and Dustin Johnson struggled.

Prior to Thursday's first round in South Carolina, Conners' best position after any round of a major was equal sixth through 54 holes at this year's Masters at Augusta.

Conners bettered that at Kiawah Island Golf Resort, where the Canadian defied the wind to set the early pace with a five-under-par 67.

Without a victory since his solitary PGA Tour triumph at the 2019 Texas Open, Conners was almost flawless in gusty conditions, holing six birdies with just one bogey.

Conners' lead marks his third career 18-hole lead/co-lead on the PGA Tour (0-for-two to date) and first at a major. Earlier this season, the 29-year-old was tied for the first-round lead at the Arnold Palmer Invitational and finished third – his best result of the season.

Koepka ended day one in a share of second position alongside Keegan Bradley, Viktor Hovland, Aaron Wise, Sam Horsfield and Cam Davis.

Koepka has been plagued by injuries since winning back-to-back PGA Championships in 2019 and a fourth major title in three years – the American star underwent knee surgery in March before missing the cut at last month's Masters.

But Koepka impressed on Thursday, overcoming a slow start to shoot a three-under-par 69.

Koepka double-bogeyed his opening hole on the back nine, however, the four-time major champion only dropped one shot after that as he tallied six birdies.

He has opened the PGA Championship with a score in the 60s in each of the last six years, the longest such streak at any major in the modern era (since 1934), eclipsing Jack Nicklaus (five – 1972-1976 Masters).

Defending champion Collin Morikawa is a stroke further back alongside the likes of five-time major winner Phil Mickelson.

Big-hitting American and reigning U.S. Open champion Bryson DeChambeau signed for an even-par 72 at the close of the first round, level with Jon Rahm and Justin Rose, while Masters holder Hideki Matsuyama, former world number one Jordan Spieth – eyeing a career Grand Slam – and Xander Schauffele shot 73s.

Jason Day and Patrick Reed were also further down the leaderboard as two-time PGA Championship winner McIlroy and world number one Johnson were powerless in the wind.

McIlroy – seeking a first major trophy since 2014 – recorded a three-over-par 75, which included six bogeys and just three birdies.

Justin Thomas also went three over for the day, while Johnson finished with two double-bogeys and a bogey in a forgettable four-over-par 76 display.

Rory McIlroy struggled on his return to Kiawah Island with a three-over-par 75 in the opening round at the US PGA Championship as playing partner Brooks Koepka impressed.

McIlroy won by eight shots the last time the PGA Championship was staged at Ocean Course in South Carolina in 2012 and was installed as the favourite of many after ending a winless streak of almost two years at the Wells Fargo Championship two weeks ago.

However, the four-time major champion – seeking a first major title since 2014 – landed his very first shot into the water on a windswept morning before recovering somewhat with back-to-back birdies on Thursday.

McIlroy – a two-time PGA Championship winner – was level par at the turn after dropping another shot on the par-five 16th, but he managed just one more birdie compared to five bogeys as he closed for 75, eight shots behind Corey Conners.

Koepka played down expectations heading into the tournament due to a knee injury and he started slowly with a double-bogey on his first hole, though the two-time PGA Championship winner recovered well with two birdies in the next three holes.

After turning in 36, Koepka picked up three shots in four holes on the front nine to complete an impressive turnaround that saw him earn a share of the lead before Conners soared to the summit as he aims to add to his successes in this event in 2018 and 2019.

"I felt like an idiot," he told Sky Sports Golf when reflecting on his cagey start. "It was probably a poor club choice off 10. I thought three-wood would have carried, but it didn't. I also didn't find the face, it barely hit the face!

"The first rule is, if you're in trouble, get the hell out. I couldn't reach the green and it was a bad lie, so I didn't know where I was going. I just tried to hit a sand-wedge up by the green instead of just chopping it out.

"So it was a mental mistake there, and I deserved every bit of that double-bogey. But it kind of helped me refocus. I can't play with any mistakes, maybe one a day, and that was my one, and I got it out of the way on the first hole."

Koepka is joined on three-under par by former champion Keegan Bradley, Viktor Hovland. Aaron Wise and Sam Horsfield.

Bradley's opening round included four birdies and just one dropped shot, coming on the par-four 13th, while Hovland bounced back from an opening bogey with four birdies.

Collin Morikawa is one shot further back after bogeying his final hole, the defending champion joined on a first-round 70 by Martin Laird, who was also let down by a couple of dropped shots on his final two holes.

Justin Thomas finds himself way down the standings, meanwhile, after carding a three over that included a double-bogey on the 18th, while US Open champion Bryson DeChambeau had a mixed first day as he posted a level-par 72.

World number one Dustin is among the late starters, along with Jordan Spieth, Tommy Fleetwood and Justin Rose.

Major glory awaits for one man at Kiawah Island on Sunday, when the winner of the US PGA Championship will be confirmed.

With such a stacked field it is hard to pick out the most likely victor, but that has not stopped Stats Peform's team of expert writers from having a go.

Last year it was Collin Morikawa who prevailed, snapping American compatriot Brooks Koepka's run of consecutive wins.

Who will it be this time?

IT'S OFFICIAL, RORY IS BACK! – Peter Hanson

Okay, I'm officially calling it – Rory McIlroy is back! At the back end of 2019 and the start of 2020, the Northern Irishman was flying. Then the coronavirus pandemic hit. Then there were some questionable decisions to start trying to match the bombs Bryson DeChambeau can nail off the tee. Then there were some ugly results – including missed cuts at the Players Championship and the Masters. But forget all that, McIlroy – just six weeks on from starting work with renowned coach Pete Cowen – was back in the winners' circle at Quail Hollow last weekend, his first title since November 2019. A McIlroy in full swagger is a joy for any golf fan, and crucially he knows how to get it done at Kiawah Island having won the first of his two PGA Championship titles at the South Carolina course back in 2012 – doing so by eight strokes, a record for the tournament. It's time for Rory to finally get that fifth major.

SCHAUFFELE HAS GOT THIS ONE – Russell Greaves

If you have this notion that Xander Schauffele always seems to be in contention at the majors, it's because he is. His tie for third at the Masters this year represented an eighth top-10 finish at a major for Schauffele, with two of those coming at the US PGA. His record is one of remarkable consistency, with only one missed cut across 14 entries in the sport's four headline events. Schauffele is one of the most adaptable players out there, as evidenced by his PGA Tour-leading sand save percentage of 69.35. At just 27, it seems inevitable he will eventually clinch a title at one of those quartet of tournaments.

HIDEKI WILL DOUBLE UP – Ben Spratt

Hideki Matsuyama had been waiting a long time for his breakthrough triumph at Augusta last month, with seven top-10 finishes at majors without reaching the winner's circle before that Masters victory. "It was a relief, really," he said last week. But having got that monkey off his back and shown he is good enough in his approach play that a poor putting game need not be a hindrance, Matsuyama can no longer be written off so easily. The Japanese will be heading to Kiawah Island full of confidence and ready to win. A second straight success would really lay down a marker.

IT'S RAHM TIME – John Skilbeck 

Sooner or later, or so goes the theory, Jon Rahm will win a major. Let's tilt towards sooner then, because Rahm is top of the PGA Tour's ball-striking chart this season, fourth in terms of finding greens in regulation and top 20 in average driving distance and scoring average. On a course set to measure over 7,800 yards, those ingredients in his game look more than useful, but Rahm will need to putt well too and that is not a given. He is down in a share of 192nd for putts per round this season, so needs to get something going with the short stick. He is developing a reputation as a Masters specialist, with four successive top-10 finishes at Augusta, and the Kiawah Island conditions will be a world away from those in Georgia. But this breakthrough at a major is going to happen sooner or later, isn't it?

RAHM'S THE ONE FOR ME – Chris Myson 

Aside from a tie for fourth at the 2018 US PGA Championship, Rahm has not made a huge impact at this event. But he is rightly among the favourites for victory this week on the back of his tie for fifth place at the Masters and his continued consistency on the PGA Tour. With six top-10 finishes to his name at major championships, Rahm has proven he can get himself into contention at the biggest events. And he comes into the latest major in form. While the world number three is yet to win this year, he has missed the cut just once in 10 events. Rahm says the recent birth of his son Kepa has helped to take the pressure off his pursuit of a first major, an occasion which is surely not far away.

Energised by the return of spectators, Rory McIlroy is confident he can end his major drought at this week's US PGA Championship.

McIlroy arrives in South Carolina buoyed by his drought-snapping victory at the Wells Fargo Championship earlier this month.

Not since November 2019 had McIlroy reigned supreme on the PGA or European Tour but the former world number one ended his wait at Quail Hollow.

McIlroy has not won a major since 2014, however the 2012 and 2014 PGA Championship winner feels good heading into Thursday's opening round.

"I'm happy with where my game is, so I guess if I go out and play my game and do what I know that I can do, then I can see myself shooting good scores on this golf course," four-time major champion McIlroy told reporters.

"So that's sort of where I'm at. Whether that means I win or not, that's partly up to me, but that's partly on how the other 155 guys in the field play, as well.

"I've just got to go out there, play my game, and if I play my game somewhat close to the best of my ability, I'm sure I'll have a good chance."

Fans returned for the Wells Fargo Championship amid the coronavirus pandemic as McIlroy thrived en route to glory and there will be fans at Kiawah Island this week.

"It's funny, ever since I was 16 years old I've had thousands of people watch me play golf pretty much every time I teed it up. Even going back to amateur golf and. So then not having that, playing in that environment for 14, 15 years and then sort of going the complete opposite, it's just different," he said.

"I said at the time it was like playing practice rounds. It's easy to lose concentration. Everyone is used to a certain environment, whether you work or whatever you do, and it's a bit. I watched the Champions League semi-finals a couple weeks ago and those guys play in that for the first time in their careers and they're playing in an empty stadium. That just must be terrible. That's not at all how you dream of being in a squad like that and playing in a massive game.

"You want to play in front of people and you want to feel that atmosphere. It's unfortunate that in these times a lot of people don't have that experience, but I am glad that we're getting back to some sort of normalcy, and when you hit good shots and hole putts there is claps and rewards and encouragement.

"I feel like that's all a part of tournament golf and competitive sports at the highest level, and just happy that I'm starting to come back."

Another former world number one, Jordan Spieth, is eyeing a milestone at the PGA Championship.

Spieth, who ended his fourth-year title drought in Texas last week, can become the sixth player in history to complete the career Grand Slam and the first to do so by winning a PGA Championship.

The three-time major winner, though, played down his career Grand Slam quest.

"I think as we get into the weekend, if I'm able to work my way into contention, I think it's something that'll obviously be asked and come up, and it's something that I certainly want," Spieth said.

"You go to a major, and for me at this point, I want to win the Masters as badly as I ever have this year. Didn't happen.

"I want to win this one as badly as I ever have. Once you move on to the U.S. Open, the same. Majors, that's what we're trying to peak for those.

"I feel like I'll have a lot of chances at this tournament, and if I just focus on trying to take advantage of this golf course, play it the best I can and kind of stay in the same form tree to green I've been in, all I can ask for is a chance."

Rory McIlroy branded plans for a Super Golf League "a money grab" as he underlined his opposition towards any breakaway competition.

A report in the Daily Telegraph this week outlined proposals for the Saudi Arabia-backed event, referred to as the Premier Golf League, with high-profile players said to have been offered hugely lucrative incentives to join.

PGA Tour commissioner Jay Monahan addressed players ahead of the Wells Fargo Championship this week, where McIlroy is playing, with a Sky Sports report indicating professionals have been warned they will face immediate expulsion from the Tour should they sign up for closed-shop competition.

European Tour chief executive Keith Pelley announced opposition towards the alternative league "in the strongest possible terms", adding: "Since the launch of our strategic alliance last November, our two organisations have been working together to make global golf less fractured and not create further division, with the interests of all players and fans at the forefront of our thinking."

McIlroy, who said he was first approached about a breakaway format seven years ago, compared the proposals to football's European Super League, plans for which were largely abandoned 48 hours after it was announced due to an outrcry from fans and key figures in the sport.

"Maybe the source of the money has changed or the people that are in charge have changed, but nothing has happened [since 2014]," McIlroy, a four-time major winner, said on Wednesday.

"If you go back to what happened last week in Europe with the European Super League in football, people can see it for what it is, which is a money grab, which is fine if that's what you're playing golf for is to make as much money as possible. Totally fine, then go and do that if that's what makes you happy.

"But I'm playing this game to try to cement my place in history and my legacy and to win major championships and to win the biggest tournaments in the world. I honestly don't think there's a better structure in place in golf, and I don't think there will be.

"You have the strategic partnership as well between Europe and the PGA Tour and that's only going to strengthen the structure of golf going forward as well in terms of scheduling and all sorts of other stuff and working together a little bit more.

"I don't think it was a coincidence that the news came out yesterday just as the PGA Tour was having their annual player meeting and Jay addressing the membership. Yeah, I think you all know my feelings on it and I'm very much against it. I don't see why anyone would be for it."

"You saw what happened last week with the European Super League. The top 12 clubs got together and said 'let's keep more of the money for ourselves', and people didn't like that. It affects competition, it affects the integrity of competition. I just can't see how it works.

"It's a complicated issue, but I just don't see at this point how it can get going. And the possibility that people, if they do go in that direction, can't play in the biggest tournaments in the game?

"The game of golf, whether it's a right thing or a wrong thing, is so about history. We still talk about Gene Sarazen and Walter Hagen and Ben Hogan and all those guys because that's what this game is. It's steeped in history and the legacies that those guys have."

Defending champion Dustin Johnson, Brooks Koepka, Sergio Garcia and Rory McIlroy all missed the cut at the Masters on Friday, while Justin Rose remains in the lead.

Johnson, who won the Masters for the first time in November, shot a three-over 75 on the second day to be five over overall and miss the cut by two strokes.

World number one Johnson made three bogeys on his final four holes to miss out, having previously impressed at Augusta, with top-10 finishes in his past five appearances.

He made four birdies on the front nine but also had two bogeys and a double bogey on the fifth.

Johnson becomes the third Masters champion in the past 15 years to miss the cut.

"Six three-putts in two rounds, you just can't do that," Johnson said. "Obviously didn't drive it great but drove it good enough.

"I never was really too bad out of position, just the three-putts killed me. You take all the three-putts away, I'm one under. That was kind of the difference."

The 36-year-old was joined by four-time major winner Koepka with a similar round to miss the cut, along with 2017 Masters winner Garcia, who shot an even round of 72 to finish at four over.

Four-time major winner McIlroy (74) and two-time Masters runner-up Lee Westwood (71) also failed to make the cut, with both unable to recover after poor first days at Augusta.

At the other end of the leaderboard, Rose sits one shot clear of Will Zalatoris and Brian Harman after a second-round 72, having led by four shots on the opening day.

Rose bogeyed four of his first seven holes on Friday, before steadying with three birdies on the back nine to salvage his lead.

"I think it was just a classic day at Augusta National when you're just slightly off," Rose said.

"You can be a foot or two out on certain occasions and you end up struggling. I think maybe off the back of yesterday, it starts to feel pretty different pretty quickly. But I told myself going up the eighth hole, you're leading the Masters, your frame of reference is a little bit different to yesterday. Four ahead is something, but you're still leading so like just enjoy it and keep going."

On his Masters debut, 24-year-old Zalatoris moved up the leaderboard swiftly, aided by five birdies on his back nine, including three straight to finish his round as he carded a four-under 68.

Harman also moved into contention after three birdies on his final six holes to finish with a three-under 69.

Australian Marc Leishman and last week's Texas Open winner Jordan Spieth are tied for fourth after both enjoyed strong rounds on Friday.

Bernd Wiesberger and Tony Finau both shot 66s on Friday to storm up the leaderboard into joint sixth alongside four other players, including world number two Justin Thomas.

Justin Rose mounted a back-nine recovery to finish his second round with a two-shot lead over Jordan Spieth and Marc Leishman.

Rose shot a sublime opening round of 65 at Augusta, but relinquished his four-shot advantage on Friday before returning to the top of the leaderboard with three birdies in his space of four holes.

The Englishman was the man to catch on seven under when he signed for a level-par 72, rallying after bogeying four of the first seven holes in his second round.

Gains at the 13th, 14th and 16th holes gave Rose momentum heading into the weekend as he bids to don the green jacket for the first time.

The in-form Spieth surged into a share of second place with Australian Leishman by carding a four-under 68, with birdies proving easier to come by for the field than on the opening day.

Three-time major champion Spieth, on a high after ending a title drought stretching back to 2017 at the Texas Open last weekend, made four of his five birdies after the turn and only dropped one shot at the 12th.

Leishman also made a significant move, setting the tone by starting with three birdies in row and going on to shoot a five-under 67.

Scintillating six-under rounds of 66 from Bernd Wiesberger and Tony Finau put them just three shots adrift of Rose along with Justin Thomas, who shot a 67.

Will Zalatoris, Brian Harman and Si Woo Kim were also well poised on four under, with their rounds still in progress. Defending champion Dustin Johnson had work to do back on three over through 10.

Bryson DeChambeau responded to a poor opening round with a 67 of his own to sit at one over, while Brooks Koepka (+5) and Rory McIlroy (+6) were facing a battle to make the cut 10 and eight holes into their rounds respectively.

Lee Westwood was a couple of shots below the projected cut mark on five over midway through his round.

Rory McIlroy's quest for a career Grand Slam may have to wait another year after an underwhelming opening day at the Masters, but he says he was encouraged by the way he finished his round.

The 31-year-old Northern Irishman made six bogeys on the first day at Augusta, finishing with a four-over 76, leaving him well off the pace set by Justin Rose with a seven-under 65.

McIlroy's best ever finish at the Masters was fourth in 2015, having won the 2012 and 2014 US PGA Championship, 2011 U.S. Open and 2014 Open Championship.

"My goal is to play well and at least give myself a chance," McIlroy told a news conference after his opening round.

"Honestly I'm quite encouraged with how I hit it on the way in. I hit some loose shots out there, but after hitting the  six iron in the water on 13, I hit some really good shots coming in, so I'm encouraged by that.

"It was just one of those days where I wasn't very efficient with my scoring.

"You're sort of fighting against momentum, but if you make a birdie then you can sort of get going, and [it was] just one of those days.

"But I hung in there, hit some good shots coming in, could have made a couple more birdies, but it's not as if anyone is going really low out there.

"Hopefully feel a little more comfortable tomorrow, go out there and shoot a good one."

There was a bizarre moment for McIlroy when his approach on the seventh hit an onlooker, which was later revealed to be his father, Gerry.

"It was a perfect shot; it was dead straight but I think he was okay," McIlroy said.

"He didn't limp away. He walked away pretty swiftly, so that was all right."

He added: "I knew it was my dad when I was aiming at him."
