Bryson DeChambeau endured a wild third round, but the FedEx Cup play-off hopeful still ended the day tied for the lead alongside Patrick Cantlay at the BMW Championship.

DeChambeau carded a five-under-par 67 to earn a share of the three-stroke lead through 54 holes at the second FedEx Cup play-off tournament on Saturday.

The 2020 U.S. Open champion's round had a little bit of everything, from back-to-back eagles to back-to-back shots in the water at Caves Valley Golf Club in Maryland.

DeChambeau was flawless on the front nine, mixing two eagles and as many birdies as he turned a one-shot deficit into a three-stroke lead within two holes.

The 27-year-old is the fourth player to make back-to-back eagles this PGA Tour season, while he is only second to Cam Davis (20) for most eagles (19).

Just as DeChambeau threatened to run away from the field, the big-hitting American stumbled, settling for a share of top spot after finding the water at the par-five 12th hole (bogey) and par-three 13th (double bogey).

"It was definitely colourful," DeChambeau – projected to be second in the FedEx Cup points race – told PGA Tour radio. "Thought I played pretty well the front nine, did mis-hit a drive on seven.

"Felt weird. From then on out I wasn't driving it very well, so that's what I'm going to do, work on that for tomorrow. If I can get that straightened out like I did the first few days, off the tee the first couple holes today, I mean, I'll give myself a great chance again."

Cantlay – the current FedEx Cup leader – is also 21 under heading into Sunday's final round following his six-under-par 66.

He was almost bogey-free on day three, holing an eagle and five birdies before bogeying the last.

Im Sung-jae is the nearest challenger after his third-round 66, while Rory McIlroy (65), Abraham Ancer (66), Sam Burns (65) and Sergio Garcia (67) are tied for fourth at 17 under.

World number one and defending champion Jon Rahm lost ground, dropping to outright eighth – five shots back – after a two-under-par 67.

FedEx Cup champion Dustin Johnson posted a seven-under-par 65 to be 14 under, while Brooks Koepka (69) ended the day a further four shots behind – two strokes better off than Justin Thomas (69).

Russell Henley carded his first bogey of the tournament but still managed to double his lead at the Wyndham Championship on Friday. 

Seeking his first PGA Tour win in four years, Henley shot 64 in the second round and sits at 14 under par for the tournament. 

That left him four strokes up on Rory Sabbatini (64), Webb Simpson (65) and Scott Piercy (66) heading into the weekend in Greensboro, North Carolina. 

Starting on the back nine at the Sedgefield Country Club, Henley bogeyed number 12, his third hole of the day, before reeling off four consecutive birdies from 14 through 17.

Three more birdies coming home after the turn solidified his edge as he eyes his first win since the 2017 Houston Open. 

Henley's 126 matches the lowest 36-hole score posted on tour this season along with Stewart Cink at the RBC Heritage. 

Tokyo Olympics silver medallist Sabbatini had a bogey-free day to match Henley's round, while Simpson remained near the top of the leaderboard thanks in part to an eagle at the fifth. 

Simpson's success is no surprise, as he has finished in the top three at the Wyndham the last four years after winning it in 2011. 

Tyler Duncan had the best round of the day with a 62 that left him five shots back at nine under along with Justin Rose (65) and Brian Stuard (66). 

Among other notables, Bubba Watson (69) and Adam Scott are 10 strokes back at four under, one shot better than the cut line. 

Masters champion Hideki Matsuyama (69) missed the cut by a stroke, while former world number one Luke Donald (67) finished at one under and two-time major winner Zach Johnson fell short at even par along with defending tournament champion Jim Herman. 

Also finished for the week-end are Padraig Harrington (76) at two over, Rickie Fowler (72) at three over and Charl Schwartzel (73) at seven over. 

Fowler's missed cut means his season is over, as he will not make the FedEx Cup playoffs for the first time in his career. 

Two players who were tied for second after Thursday's opening round, Michael Thompson and Ted Potter Jr., also missed the cut after slumping to 74 and 77, respectively. 

Abraham Ancer thought he had blown his shot at his first PGA Tour win the first time he played the 18th hole on Sunday. Turns out he just needed two more chances on the hole to make it happen. 

Ancer birdied the second playoff hole from six feet and watched as Sam Burns missed almost the same putt to give him the WGC FedEx St. Jude Invitational title as the third man in the playoff, Hideki Matsuyama, also made par. 

After finishing as runner-up four times in his previous 120 Tour starts, Ancer finally prevailed in Memphis to become the ninth first-time winner this season and the fourth player from Mexico to win on Tour. 

"This is surreal," he told CBS. "I thought I left so many shots out there on the back nine, but you never know. Golf is crazy.

"There's been some times that I felt like I made enough birdies to win and I didn't win. This is kind of how it goes and I'm happy that I got lucky."

A significant portion of that luck came on the first playoff hole, when Matsuyama had a chance to win it but saw his long putt for birdie on 18 lip out, sending the trio back to the 18th tee for another go.

The 2021 Masters champion turned in the round of the day just to make the playoff, firing a bogey-free seven-under 63 to fly up the leaderboard on the final day. 

Burns was close behind with a 64, a double bogey on 13 his only blemish. 

Harris English, who held a two-stroke lead after each of the first three rounds, watched those three fly by him as he slumped to a three-over 73 and finished fourth after opening the tournament with rounds of 62, 65 and 65. 

English bogeyed the opening hole before regaining his stride with three birdies, but he did not make another after the eighth hole, posting double bogeys at 11 and 14 and a bogey at the par-five 16th. 

The American said afterward that a warning for slow play on the front nine knocked him out of rhythm and he felt like he was rushing the rest of the day.

His playing partner Bryson DeChambeau had an even more difficult time after working himself into contention with a 63 on Saturday. 

DeChambeau carded a triple-bogey six on the 11th and also did not manage a birdie on the back nine on the way to a 74 that left him tied for eighth at 12 under for the tournament. 

Rough as that triple was for DeChambeau, honours for worst hole of the day went to Kim Si-woo.

The South Korean hit five successive shots in the water at the 11th on the way to a 13 – the worst score on a par-three hole on the PGA Tour since 1983, not including majors.

Among other notables, Dustin Johnson (70) tied for 10th at 11 under, one stroke better than Rory McIlroy (66) and Jordan Spieth (67).

Phil Mickelson (68) finished at seven under along with Louis Oosthuizen, who floundered to a 74 in the final round. 

Sergio Garcia (72), Collin Morikawa (69) and defending champion Justin Thomas (72) were at five under, with Patrick Reed (70) and Lee Westwood (71) one back of them. 

Olympic champion Xander Schauffele (68) was at even par and Brooks Koepka (76) at two over. 

Harris English maintained his two-shot cushion at the WGC-FedEx St. Jude Invitational leaderboard as Bryson DeChambeau climbed up the leaderboard.

Aided by three birdies during his final six holes, English carded a second successive score of 65 at TPC Southwind to sit at 18 under par.

The four-time winner on the PGA Tour endured a bogey-free round on Saturday, pulling clear in the closing stages having at one stage seen both Abraham Ancer and DeChambeau join him in top spot.

After a four at the par-five 16th, English produced an outstanding approach into the green at the next hole before rolling in a birdie putt, boosting his hopes of a wire-to-wire triumph in the tournament.

However, he is well aware that there is still plenty of work to do yet.

"There's a lot of good players behind me and my goal is just stick to my strategy and execute and whatever happens, happens," English said.

DeChambeau is not too far behind after a stunning 63 that saw him come home in just 30 shots. His seven-under score leaves him tied for second with Australian Cameron Smith, who signed for a 65.

"It was awesome being able to strike it that close to the hole all day," DeChambeau, who missed out on playing at the Tokyo Olympics due to contracting coronavirus, said.

"I didn't feel as comfortable as I would have liked with the swing, but the results were there so I was very pleased with the results. And honestly, if I can do that again tomorrow, I give myself a great chance to win."

Ancer is a further two strokes back following a three-under 67, the same score Scottie Scheffler and Ian Poulter both managed to sit just behind the Mexican on 13 under.

Dustin Johnson may still hold out hope of triumphing, with a round of 65 enough to be one of four players on 11 under par.  He is joined by Paul Casey, Will Zalatoris and Louis Oosthuizen.

Defending champion Justin Thomas already faced a battle to retain his crown, and the American was only able to shoot 69 on day three.

At seven under for the event, a repeat of his 2020 triumph appears almost impossible, considering he is so far back and the number of players ahead of him.

Harris English heads into the weekend at the WGC-FedEx St. Jude Invitational with a two-stroke lead after maintaining his spot atop the leaderboard Friday.

The American followed Thursday's 62 with a five-under-par 65 at TPC Southwind, where he won his first PGA Tour title eight years ago. 

Australia's Cameron Smith and Abraham Ancer of Mexico surged into a tie for second place after carding 62s of their own in Memphis to sit at 11 under for the tournament.

Ian Poulter (66), Scottie Scheffler (65) and Sam Burns (64) are three back of the lead at 10 under, while Louis Oosthuizen (64) and Bryson DeChambeau (66) are well within striking distance at nine under. 

English started on the back nine and made three birdies going out before carding his first and only bogey of the day at the par-four second hole. But he managed to follow that disappointment with an eagle on the third before adding one more birdie later in his round.

Smith also eagled the third on the way to tying a PGA Tour record, as he needed just 18 putts to complete his bogey-free round. 

That included a two-put at the last, not long after Smith figured out he was on the verge of history. 

"I was walking down 17 and was counting my putts up and I thought, 'No, that can't be right,'" Smith said. 

Further down the leaderboard, defending champion Justin Thomas (67) is seven strokes back of the lead at six under along with two-time major winner Dustin Johnson (65).

Phil Mickelson (66) is at five under, whie Hideki Matsuyama (69) and Patrick Reed (69) are well back at three under. 

Rory McIlroy (66), Sergio Garcia (68), and Collin Morikawa (71) are at two under, one stroke better than Brooks Koepka (69). 

Jordan Spieth (69) enters the weekend at even par and Olympic champion Xander Schauffele (73) is at two over. 

Harris English won his first PGA Tour title at TPC Southwind eight years ago, and he has another triumph in his sights after opening with a 62 at the WGC-FedEx St. Jude Invitational. 

The American has a two-stroke lead over four pursuers, as Ian Poulter, Carlos Ortiz, Jim Herman and Matthew Wolff carded six-under-par 64s Thursday in Memphis, Tennessee. 

Bryson DeChambeau, Scottie Scheffler and Marc Leishman were three shots back after shooting 65, with DeChambeau making his first start since missing the Tokyo Olympics following a positive COVID-19 test. 

Among the group two shots behind them at five under were defending champion Justin Thomas, Open Championship winner Collin Morikawa and the red-hot Louis Oosthuizen, who has top-three finishes in four of his last five starts.

Among other notables, Patrick Reed and Hideki Matsuyama are at two under, with Phil Mickelson, Dustin Johnson and Olympic champion Xander Schauffele at one under, and Brooks Kopeka and Sergio Garcia at even par.

Jordan Spieth is at one over and Rory McIlroy at two over, leaving him 62nd in the 66-player field. 

But they will all start Friday chasing English. The 32-year-old carded seven birdies on a blistering front nine, then faltered a bit with bogeys at 10 and 12 before closing his round with birdies at three of the last four holes. 

"It was one of those rounds where I was hitting it really good off the tee and making a lot of good putts," English told reporters. 

English won at Memphis in its previous incarnation as the Tour's St. Jude Classic in June 2013, then added another title that fall. 

That was his last PGA Tour win before this year, which has seen him take the Tournament of Champions in Maui in January and the Travelers Championship in June. 

Sepp Straka was the surprise leader of the golf competition after round one at Tokyo 2020 thanks to a dazzling and record-equalling eight-under 63 at Kasumigaseki Country Club.

The 161st-ranked Austrian sat one stroke clear of Jazz Janewattananond, with Thomas Pieters and Carlos Ortiz only two strokes back.

Play was delayed for around two hours on Thursday due to dangerous weather conditions and a host of star names were off the pace after the first 18 holes.

STRAKA SURPRISES TO EARN SHARE OF HISTORY

The unheralded Straka, whose twin brother is on his bag this weekend, tied the record for the lowest single-round score at an Olympics with his 63.

"It was just a steady round. I really hit the ball well and I didn't put myself into trouble. I took advantage with the putter," Straka said.

"I got hot with my irons, especially my short irons, my wedges. I was really knocking down the flagstick and really tried to stay aggressive."

He made four gains on the way out and as many on the way home in a fine bogey-free round, and this round came despite him missing six of his past seven cuts.

HIDEKI, MCILROY AND CO HAVE WORK TO DO

Masters champion Hideki Matsuyama is carrying the home hopes in Tokyo this week and was six shots back.

He was four under through eight but gave one back before the turn and dropped another shot at 11.

Rory McIlroy and Open victor Collin Morikawa are also at two under, with Patrick Reed five back and Justin Thomas at evens after making 18 pars.

Jon Rahm has been ruled out of competing at the Tokyo Olympics after testing positive for COVID-19.

The Spanish Olympic Committee announced the world number one had returned a positive result on his third PCR test after competing at The Open at Royal St George's, having previously recorded two negative outcomes ahead of his appearance at the Games.

American Bryson DeChambeau was also ruled out of competing for the same reason on Sunday, having not yet travelled to play in Japan.

For Rahm, it is the second time he has tested positive in as many months. He had to withdraw from the Memorial Tournament on the PGA Tour when leading by six shots after 54 holes.

The 26-year-old won the U.S. Open upon his return to action, securing the first major of his career by one shot thanks to a birdie-birdie finish on a dramatic Sunday at Torrey Pines.

With a shortage of time and considering the health protocols in place for the Olympics, a replacement will not be selected. Spain still has one competitor left in the field in Adri Arnaus, the world number 166.

As for DeChambeau, he admitted to being "deeply disappointed" at missing out on Tokyo.

"Representing my country means the world to me and it is was a tremendous honour to make this team," he said in a statement released by the PGA Tour.

"I wish Team USA the best of luck next week in Tokyo. I will now focus on getting healthy, and I look forward to returning to competition once I am cleared to do so."

Patrick Reed will replace him, provided he clears coronavirus tests scheduled on Sunday and Monday before departing for Japan.

Cam Tringale moved into the lead ahead of the final day at the 3M Open in Minnesota after carding a five-under round including an eagle on Saturday.

The American raced up the leaderboard as overnight joint leaders Ryan Armour and Adam Hadwin and slid, with an even round and two-over respectively at TPC Twin Cities.

Tringale's surge was set up after becoming only the third player to reach the par-five 12th in two, sitting at 12 under after 54 holes.

He enjoyed a bogey-free third round, birdieing his first two holes, with only Beau Hossler, who is joint for 12th, bettering his round on Saturday with a six-under-65.

Gary Woodland and Maverick McNealy are joint in second on 11 under after strong third day rounds.

Pat Perez, Cameron Champ, Jimmy Walker and Charl Schwartzel are all 10 under. Champ looms large having carded 10 under from his past 27 holes.

Rickie Fowler appeared set to contend again but carded an eight on the 18th hole to finish six off the lead having found the water.

He was not alone in struggling on the 18th which saw five bogeys, three double bogeys and seven triple bogeys or worse.

The 149th Open Championship concluded in thrilling fashion on Sunday as Collin Morikawa claimed the Claret Jug.

It was a fitting finale to a memorable tournament, which marked the return of fans en masse to watch golf's oldest major.

Royal St George's was bathed in sunshine for all four days and it was a joyous event for everyone in attendance.

Stats Perform's man on the ground said a fond farewell to the Kent links, but not before one last wander around the course.

SHELTER FROM THE WARM

The soaring temperatures made walking the course a test of endurance, and not everyone was keen to partake.

What few spots of shade there were soon became occupied by weary bodies, sheltering from the warmth of the sun.

The queues at the water refill points were longer than for the grandstands.

CELEB SPOTTING (TAKE TWO)

It may have been premature to share the story of a chance encounter with British comedian Michael McIntyre on Saturday, as Sunday heralded the arrival of an even bigger celebrity.

Milling around outside the entrance to the media centre, and somehow not surrounded by a large crowd of autograph hunters, was One Direction's Niall Horan.

He's a keen golf fan and can often be seen at the majors rubbing shoulders with the biggest names in the sport.

FLAGGING...

At the end of a long tournament, some members of the media pack wanted a morale-boosting moment, so waited patiently for Champion Golfer of the Year Morikawa to exit from the interview room in hope of an autograph or photo.

Two had souvenir flags with Open Championship branding, in the expectation Morikawa might take the time to sign them.

He bolted through the doors carrying the Claret Jug, saw his waiting fans, but had no time to stop, telling them: "Sorry guys. Maybe I'll see you later."

Oh, the disappointment. 

Open champion Collin Morikawa revealed the unexpected and tasty secret to his success after winning the Claret Jug at the first attempt on Sunday.

The 24-year-old produced a blemish-free 66 in a stunning final round at Royal St George's to thwart the charge of Jordan Spieth and eclipse overnight leader Louis Oosthuizen.

Morikawa, who also won the 2020 US PGA Championship on debut, secured his second major win in eight entries after starting the day a shot behind Oosthuizen.

In the end his greatest beef was with 2017 Champion Golfer of the Year Spieth, who recovered from being two over through six holes to sign for a 66 himself, finishing two back.

But Morikawa, who saw playing partner Oosthuizen limp to a closing 71, clearly relished the challenge as he went bogey-free to make mincemeat of the field in sizzling sunshine on the Kent coast.

But, when grilled by the media as to what the key to his triumph was, Morikawa had an answer nobody saw coming.

"The secret? Well, I never do this, but I had a burger for four straight days, so my body is probably feeling it. I know my body's feeling it," he said.

"I think I just enjoy these moments, and I talk about it so much that we love what we do. And you have to embrace it.

"You have to be excited about these opportunities, and that's how I looked at it today, especially coming down the stretch, was I'm excited. To have the Claret Jug right here in my possession for a year, I believe, I'm excited to have it."

Runner-up Spieth lamented his putting as he came up short, but Morikawa was delighted with that side of his own game.

He made a succession of potentially tricky putts, including one for birdie from around 15 feet on the 14th just after Spieth had cut the gap to one.

"Definitely one of the best [putting displays], especially inside 10 feet," he said.

"I felt like it was as solid as it's going to get. I don't think I really missed many from that distance. Especially in a major.

"I think in a major on a Sunday in contention, I wasn't thinking about anything other than making a putt.

"I'm going to tell myself probably tomorrow: 'Why can't I keep doing that all the time?'.

"But you know, I'm going to try to figure out what worked and use that for the future because I know I can putt well. I know I can putt well in these pressure situations. I've just got to keep doing that."

Jordan Spieth was left to lament a slack finish to his third round after he came up just short at The Open on Sunday.

The 2017 Champion Golfer of the Year recovered from two over through six to sign for a final-round 66, which left him two shots shy of winner Collin Morikawa.

But it was Saturday's round at Royal St George's that bothered the three-time major winner, who dropped shots at each of the last two holes.

Reflecting on a close call with what would have been a first major triumph since that success at Royal Birkdale four years ago, Spieth was quick to point out where it went wrong.

"It's hard to be upset when I was a couple over through six," he said. "I couldn't have really done much more after that point.

"But the finish yesterday was about as upset as I've taken a finish of a round to the house. I walked in and I said: 'Is there something that I can break?'.

"I knew that was so important because I would have been in the final group."

Spieth is usually a safe bet with the putter in his hand, but the 27-year-old felt that side of his game was lacking in Kent.

He took 1.58 putts per greens in regulation, which was better than the field average of 1.68, but Spieth felt he was well short of his own high standard.

"My putting is not where I want to be at all," conceded. "I say at all; It's progressing the right direction, but it's not where it has been.

"I know what needs to do to get there, and it's just very difficult to do. But it's rounds like today or this week, major championship rounds, where you have to obviously test not only your touch out here, but also a lot of knobs and breaking putts and trust lines. It's a good test for it.

"I just wasn't extremely sharp with the putter this week. I was sharper than I was at Augusta, and it's been a little bit kind of here and there this year.

"My bad weeks have been okay and my good weeks are really good, but I needed to put in a little bit of work."

Paying tribute to champion Morikawa, who has two major wins from eight starts, Spieth added: "He swings the club beautifully, gets it in positions that make it very, very difficult to not start the ball online, so therefore, he's going to be very consistent tee to green.

"At 24, obviously there's a bright future ahead."

Collin Morikawa produced a stunning final round to win The Open by two strokes from Jordan Spieth at Royal St George's.

The 2020 US PGA Championship winner added a second major to his list of honours in only his eighth appearance in such tournaments, with this his debut at the oldest of golf's four headline events.

His blemish-free 66 on Sunday ensured he overturned the one-stroke overnight lead that Louis Oosthuizen had held, while Spieth closed with the same score as he came up just short.

Morikawa nailed a lengthy birdie putt on the 14th, just after Spieth's run of four gains in four holes around the turn had cut the gap to one, and the 24-year-old never looked back as he sealed the prize on 15 under.

Spieth, the 2017 champion at Royal Birkdale, and Oosthuizen, who triumphed at St Andrews in 2010, had each been chasing a second Claret Jug.

But Morikawa showed nerves of steel as he refused to wilt in the sunshine on the Kent coast, the American averaging 1.5 putts per greens in regulation.

He needed to hit such a high level to keep Spieth at bay, his compatriot rallying from two over for the day after six holes to close at 13 under.

Oosthuizen endured the frustration of finishing as runner-up at the US PGA Championship and the U.S. Open this year and he suffered more disappointment following a closing 71.

Pre-tournament favourite Jon Rahm wrapped things up in style with a 66 and he will return to the world number one spot next week, displacing Dustin Johnson. 

Reigning champion Shane Lowry finished at six under, while Rory McIlroy closed with a 71 to wrap up a low-key outing at even par.

SHOT OF THE DAY

Morikawa's approach shot on the 14th was short and left him with a long uphill putt for birdie on a par five that was playing at a generous average of 4.6.

Spieth was on the charge and momentum looked to shift in the three-time major winner's favour, but Morikawa turned a potential negative into an overwhelming positive with one decisive swipe of the putting blade.

It was the point at which the engravers may as well have started putting his name on the silverware.

CHIPPING IN

Shane Lowry: "I really enjoyed the whole week. It was an amazing experience. Walking down the last hole today was one of the coolest things you'll ever get to do, and I got to do it."

Rory McIlroy: "For me at the minute it's just the process of trying to work my way back to the sort of form and the sort of the level that I know I can play at."

Brooks Koepka: "I like coming over here and playing links golf. It's always a bunch of fun, and I've always said that it's the one tournament a year where the fans actually know what a good shot is."

A LITTLE BIRDIE TOLD ME

- Louis Oosthuizen's last three major results are now tied second (US PGA Championship), second (U.S. Open), and tied third (The Open).

- Shane Lowry's failure to retain the Claret Jug means no player has successfully defended the honour at Royal St George's since Harry Vardon in 1899.

- Germany's Matthias Schmid won the silver medal for low amateur after finishing two over par.

Collin Morikawa held the lead after nine holes of the final round at The Open as Louis Oosthuizen slipped back on Sunday.

Morikawa, the 2020 US PGA Championship winner, reached the turn 14 under overall as the American moved four strokes clear of overnight leader Oosthuizen, with Jordan Spieth now his closest rival.

South African Oosthuizen is eyeing a wire-to-wire triumph at Royal St George's, where he and Spieth are each looking to lift the Claret Jug for a second time.

Oosthuizen won it in 2010 at St Andrews, while Spieth – who was 11 under through 10 – triumphed at Royal Birkdale in 2017.

It would be a bitter pill to swallow for Oosthuizen should he miss out in Kent, as he has already endured two runner-up finishes in majors this year and six in his career.

Jon Rahm got himself into the mix at eight under through six before giving a stroke back, with Corey Conners, and Dylan Frittelli on the fringes.

Four-time major winner Brooks Koepka carded a final-round 65 to close on eight under, leaving him to lament Saturday's 72.

"It's definitely a missed opportunity," he said. "I didn't play good enough on Saturday. Doesn't really matter what I finished today. I didn't have a chance to win. That's disappointing."

Louis Oosthuizen will tee off his final round at The Open on Sunday with a one-shot lead over playing partner Collin Morikawa.

The 2010 winner, who has finished as runner-up six times in majors, is eyeing a wire-to-wire victory at Royal St George's, where he starts his fourth round at 14:35 local time at 12 under.

American Morikawa also has a second major in his sights, having claimed the 2020 US PGA Championship.

Jordan Spieth is firmly in the mix, the three-time major winner and 2017 Champion Golfer of the Year at nine under, while pre-tournament favourite Jon Rahm is two strokes further back.

Corey Conners and Scottie Scheffler are each on eight under and hoping to earn maiden major triumphs.

Glorious weather means the course is set fair for low scoring for anyone who can summon the courage and accuracy to take on some tough pin positions at the Kent links.

There was promise in the early scores coming in, with American trio Rickie Fowler, Xander Schauffele and Bryson DeChambeau all shooting 65.

If any of the leading trio should go that low, it will rule out the chasing pack and reduce the contenders down to the final couple of groups on course.

That would mean Brooks Koepka's surge up the leaderboard would still leave him short, the four-time major winner having made the turn in 31.
