Brooks Koepka would relish a Sunday showdown with rival Bryson DeChambeau at The Open as the pair's feud continued at Royal St George's.

The American duo have been exchanging barbs for a long while now, with Koepka invited to offer an explanation when he faced the media ahead of the 149th Open in Kent on Tuesday.

Koepka revealed the issue started at the 2019 Northern Trust at Liberty National after he called out his compatriot for slow play.

A disgruntled DeChambeau took it up with Koepka's caddie, Ricky Elliott, before the pair apparently decided to call it quits, only for DeChambeau to stoke the fire with some unflattering comments about his countryman during a public online video game session.

Four-time major winner Koepka explained: "It was at Liberty. He didn't like that I had mentioned his name in slow play, so we had a conversation in the locker room, and then I guess we said something else in the press conference but didn't mention his name in it, and he walked up to Ricky and said: 'You tell your man if he's got something to say, say it to me.'

"I thought that was ironic because he went straight to Ricky. Ricky told me when I came out, I hit a few putts, and then just walked right over to him, we had a conversation.

"We both agreed we'd leave each other out of it and wouldn't mention each other, just kind of let it die off, wouldn't mention each other's names, just go about it.

"So then he decided I guess he was going on that little, whatever, playing video games online or whatever and brought my name up and said a few things, so now it's fair game."

Asked about the prospect of being paired with DeChambeau for the final round at golf's oldest major this weekend, Koepka said he would be up for the battle.

"Yeah, I would enjoy it. I would enjoy it. I'll be close to the final group come Sunday," he said.

"I always feel like I play well in the big events, the majors. I think it would be a lot more people tuning in, with everything that's gone on over the last two years, something like that, three years. So yeah, I think there would be a lot of people tuning in."

With the Ryder Cup to come at Whistling Straits in September, the two are set to be team-mates, but Koepka can handle a week of being on the same side.

"It's only a week. I mean, look, I can put it aside for business," he said.

"If we're going to be on the same team, I can deal with anybody in the world for a week. I'm not playing with him.

"I'm pretty sure we're not going to be paired together; put it that way. I think it's kind of obvious. It doesn't matter.

"We're not going to be high-fiving and having late-night conversations. I do my thing, he does his thing."

Speaking later the same day, DeChambeau was a little more succinct, saying of Koepka: "He can say whatever he wants. I think he said something back at Liberty National not upholding something. I don't know what he's talking about in that regard."

Rory McIlroy believes missing the cut at the Scottish Open could prove beneficial as he bids for glory at The Open.

The four-time major winner, who claimed the Claret Jug in 2014, endured a testing couple of days at the Renaissance Club, where an intruder attempted to steal his club.

McIlroy failed to make the weekend but that gave the 32-year-old extra preparation time ahead of the 149th Open at Royal St George's.

He will try to atone for a poor showing at the 2019 edition of golf's oldest major, where he missed the cut as the home hope at Royal Portrush.

The omens bode well for McIlroy, who has bounced back to win the next tournament in three of the previous nine instances where he has seen his campaign ended after two rounds.

Asked if that fact was mere coincidence, McIlroy said: "No, I certainly don't think it's a chance statistic.

"Look, I think in golf you always learn more about your game when you've missed a cut or struggled or not played as well. I think anyone can play well, anyone can hit the ball great and give themselves chances to win, but you just learn more.

"I've always learnt more from disappointments and from not doing as well, but I've always tried to learn. I've always tried to figure out, okay, why did this week not go so well, and then you give yourself a couple of thoughts and they're fresh in your mind going into the next week.

"That's why I say in golf there's always next week, and that's a great thing, because you can right some wrongs pretty quickly. I've been able to do that in the past.

"I missed the cut at Memorial a couple years ago, went down and won the Canadian Open the next week. Yeah, missed the cut at the Masters and then went and my next start was Quail Hollow and I won.

"Golf always just gives you another opportunity to go out and play well and to see if you've learned from your mistakes, and I've always made it a priority in my career to really try to learn from my mistakes, all the way back to what happened at Augusta in 2011 and going and winning the U.S. Open the next major."

Indeed, after his disappointment in Northern Ireland in 2019, McIlroy closed that year by winning the FedExCup, which he said "gave me a few million reasons to feel better".

He will tee off at the Kent links in pursuit of a second Open title on Thursday at 15:21 local time alongside Patrick Reed and Cameron Smith.

Jon Rahm is eyeing a historic double at The Open Championship this week as he seeks to add to his U.S. Open triumph.

The Spaniard is among the leading contenders at Royal St George's after claiming his maiden major at Torrey Pines last month.

Just six players have doubled up by winning both The Open and the U.S. Open in the same year, with Bobby Jones having done so twice before Gene Sarazen, Ben Hogan, Lee Trevino, Tom Watson and Tiger Woods repeated the feat.

Woods managed it in 2000 and Rahm has the chance to join that elite club 21 years on.

"It would be pretty incredible to win both Opens in one year. It would be amazing," said Rahm.

"I did have a sense of relief after winning the first major. I felt like for the better part of five years, all I heard is major, major, major just because I was playing good golf, as if it was easy to win a major championship.

"But the fact that you are expected to win one means nothing, but you're playing good golf, so a bit of relief in that sense, but it doesn't really change.

"There's still the next one to win, so I still come with the same level of excitement obviously and willingness to win.

"I'm focused on the fact it would be pretty incredible to be able to win The Open. Nobody after Seve has been able to do that [from Spain]."

Rahm, who will tee off alongside reigning champion Shane Lowry and 2010 winner Louis Oosthuizen on Thursday, also underlined why he was sticking to his plans to play at the Olympics despite many players having opted out of competing in Japan.

"I can't speak for other people, so I don't know why they're opting out of it, you'd have to ask them," he said.

"I'm not going to speak for them. In my case, I've been really fortunate enough to represent Spain at every level as an amateur since I was 13 years old.

"I've been able to win many team events representing Spain worldwide. Once you turn professional you don't really get that chance. You get a little bit of the Ryder Cup, but it's not the same thing as the Olympics or a World Cup maybe.

"To be able to have that chance as a pro, something that up until four or five years ago was not even a possibility, to me it was something I would never doubt.

"You get the chance to call yourself an Olympian, which is only a very select group of people in history that can call themselves that, and if you were to get a medal, especially a gold medal, you're even more of a select group, right?"

U.S. Open winner Jon Rahm will tee off alongside 2019 Champion Golfer of the Year Shane Lowry at the 2021 Open Championship on Thursday.

Spaniard Rahm won his maiden major at Torrey Pines, edging out Louis Oosthuizen by one stroke, and is among the favourites to prevail at Royal St George's this week. 

Lowry was a popular winner when golf's oldest major was held at Royal Portrush two years ago, with the 2020 event having been cancelled amid the coronavirus pandemic.

The Irishman, whose trio goes out at 09:58 local time and also includes 2010 victor Oosthuizen, will seek to become the first man to defend the Claret Jug at the Kent links since Harry Vardon in 1899.

Any superstitious players might have hoped to be drawn in Branden Grace's group, as he has played with the eventual winner in his first two rounds at each of the previous two Opens.

The South African featured with Francesco Molinari at Carnoustie in 2018 and Lowry in Northern Ireland the following year. 

Jordan Spieth, a winner in 2017, and 2020 U.S. Open champion Bryson DeChambeau are the lucky pair, with that group teeing off at 09:25.

Four-time major champion Rory McIlroy will head out in the afternoon with Patrick Reed and Cameron Smith, while world number one Dustin Johnson starts his bid for a first Open title at 10:20 with Will Zalatoris and Justin Rose for company.

Brooks Koepka is an 08:45 starter and the star attraction of a threesome that includes Jason Kokrak and Garrick Higgo.

Darren Clarke, who prevailed when last Royal St George's last hosted in 2011, is an 08:25 starter alongside Bernd Wiesberger and amateur Joe Long.

The action will begin at 06:35, with English trio Richard Bland, Andy Sullivan and Marcus Armitage having the honour.

Two-time former Masters champion Bubba Watson has withdrawn from the Open Championship.

Watson, who finished sixth last week at the Rocket Mortgage Classic, said he had come into contact with somebody who has been confirmed as having the COVID-19 virus.

The 42-year-old must therefore stay at home in the United States rather than travel to England for the major, which begins at Royal St George's in Kent on Thursday.

Watson posted a statement to his social media accounts that read: "I am disappointed to announce I will not compete at the Open Championship next week due to having direct exposure to someone who has tested positive for COVID-19.

"While I am vaccinated and have passed the required pre-travel COVID test, not enough time has passed for me to comfortably join the charter flight and risk exposure to the other players and personnel on board."

He added: "Like many of you, I look forward to watching the Open Championship on TV. Since I will be watching from the comfort of my couch I would not mind seeing the field have to deal with a little rain and strong winds!

"Best of luck to all the players. I look forward to returning to the Open Championship next year."

Watson won the Masters in 2012 and 2014 but has often struggled at The Open, which is the only one of the four majors at which he has failed to register a top-five finish. Indeed, his best performance has been a tie for 23rd place at the 2012 tournament.

John Deere Classic leader Luke List was delighted to be back out on the course and enjoying his golf after a tough time of things in his personal life.

List's newborn son Harrison was in intensive care after contracting a respiratory virus but is thankfully now home and recovering.

However, it was a difficult few weeks for List, who shot a 63 on Friday tomove a shot clear of joint overnight leader Sebastian Munoz.

"It was tough, but it's been amazing to come back," he said.

"Everyone has been asking and praying and thinking about us, so it's kind of cool.

"It's a big family out here, and it's nice to know that you've got everyone's support when it's not going great."

List's card showed eight birdies as he moved to 13 under for the tournament, one clear of Munoz after the Colombian's 67.

A group of seven players sit on 11 under in a tightly congested leaderboard. 

Graeme McDowell and Martin Kaymer have been appointed as vice-captains by Team Europe skipper Padraig Harrington for the Ryder Cup.

Both players bring a wealth experience to Harrington's backroom team for the rescheduled clash against the United States, which will take place at Whistling Straits in September – 12 months on from the original date that was scuppered by the coronavirus pandemic.

McDowell was also part of the set-up at Le Golf National in 2018, where Europe – led by Thomas Bjorn – hammered their American counterparts 17.5-10.5.

The Northern Irishman has featured four times as a player (2008, 2010, 2012, 2014), accumulating nine points from 15 matches – including claiming the winning point at Celtic Manor in 2010.

"I decided on Graeme as a vice-captain a long time ago. He was vice-captain in 2018 with me and I liked what he brought to the team room," Harrington said of the 2010 U.S. Open champion.

"He's quite an authority, confident in what he's doing and saying and knows the scene. The only reason he would not have been a vice-captain was if he was going to be a player.

"Graeme is a strong influence and the players look up to him. When he speaks, people listen, but he doesn't speak unless he's got something to say. I definitely saw that when he was vice-captain previously – players pay attention and follow him."

Kaymer too brings plenty of Ryder Cup experience to the table. The German has won 6.5 points from four appearances at the biennial tournament (2010, 2012, 2014 and 2016).

Undoubtedly his most famous contribution came when he sank the winning putt in 2012 to complete the "Miracle of Medinah", where Europe overturned a 10-6 deficit on the final day to retain the trophy.

Whistling Straits is also the scene of Kaymer's 2010 US PGA Championship triumph, which led to his debut in the Ryder Cup. 

"Martin is somebody I wanted as a vice-captain because he has a great personality and brings a calmness, a European element, and a lot of confidence with him," Harrington said of Kaymer, who also won the 2014 U.S. Open. 

"The fact that he won around Whistling Straits also brings that level of authority and assurance that you need.

"Martin will also bring a nice emotion to the team, which is very important. He's somebody who will help with the atmosphere, put an arm around a player or two and bring that level of authority and belief that we may need during the week."

Jon Rahm birdied his final two holes to outlast Louis Oosthuizen by one stroke for U.S. Open victory and his first major title.

Oosthuizen was in a three-way share of the lead heading into the deciding round and opened up a one-shot lead on a gripping final day at Torrey Pines.

But Rahm rallied in San Diego, where the emotional Spanish star dramatically birdied the 17th and 18th holes to claim a lead he never relinquished on Sunday.

Rahm signed for a four-under-par 67 to finish six under through 72 holes as 2010 Open Championship winner Oosthuizen (71) settled for a runners-up cheque.

At the scene of his maiden PGA Tour win – the 2017 Farmers Insurance Open – Rahm became the fourth player from Spain to win a major and first at the U.S. Open.

Rahm, who was forced to withdraw from the Memorial Tournament when leading by six shots after testing positive for coronavirus earlier this month, said post-round: "I'm a big believer in karma. After what happened a couple of weeks ago, I stayed really positive, knowing big things were coming.

"I didn't know what it was going to be, but I knew we were coming to a special place, I know I got my breakthrough win here, and it's a very special place for my family. The fact my parents were able to come, I got out of COVID protocol early, I just felt like the stars were aligning.

"I can't even believe I made the first two putts! This was definitely for Seve [Ballesteros]. I know he tried a lot, and wanted to win this one most of all. I just don't know how to explain it! I don't know why, but every time we land here, we are happy. We’re in our spot!"

Oosthuizen was initially circumspect on day four, going one over through eight holes to leave the South African one shot behind defending champion Bryson DeChambeau – who came agonisingly close to a sensational hole-in-one at the par-three eighth.

But DeChambeau was unable to maintain his hot start, finishing with a forgettable six-over-par 77 to end the event eight shots off the pace.

Oosthuizen also failed to keep Rahm at bay – dropped shots at the 11th and 17th holes, paving the way for the red-hot Spanish golfer to emerge triumphant for the first time at a major.

Harris English (68) finished solo third, a stroke better off than Guido Migliozzi (68), two-time U.S. Open winner Brooks Koepka (69) and Collin Morikawa (70) as former world number one Rory McIlroy's final-round 73 resulted in a share of seventh spot at one under.

World number one Dustin Johnson (74) and fellow stars Jordan Spieth (72) Justin Thomas (73), Patrick Reed (67) and Sergio Garcia (68) closed out the event tied for 19th.

Louis Oosthuizen opened up a one-shot lead in a gripping final round at the U.S. Open.

Oosthuizen was in a three-way share of the lead heading into Sunday at Torrey Pines but was initially circumspect, going one over through eight.

That put the 2010 Open winner a shot behind defending champion Bryson DeChambeau, who came agonisingly close to a sensational hole-in-one at the par-three eighth.

That birdie result was enough for the outright lead on five under at the turn, although the American's first bogey of the weekend on 11 came as Oosthuizen's putter heated up, picking up shots on nine and 10. Oosthuizen dropped one at 11 though.

DeChambeau erred again, meaning Jon Rahm – who flew out of the blocks with back-to-back birdies – was the nearest challenger to Oosthuizen alongside another overnight leader Mackenzie Hughes on four under.

Rory McIlroy drained a 35-footer on the fourth, leaving him well-placed early on minus four.

However, the Northern Irishman passed up three further birdie opportunities by the midway point of his round and his hopes were fading when he bogeyed the 11th.

That left McIlroy level on three under with Brooks Koepka, although the American four-time major winner was through 16 holes and appeared to have missed his moment to make a decisive move.

The 2020 US PGA champion Collin Morikawa was one of the pack on four under until he went through the green on 13 and left with a double bogey.

Louis Henley was alongside Oosthuizen and Hughes in the clubhouse on Saturday but also dropped back to minus two, albeit in less spectacular fashion than Morikawa.

Bryson DeChambeau is fully embracing the atmosphere created by the so-called 'Brooksy bros' at the U.S. Open.

There is little love lost between defending champion DeChambeau and two-time winner Brooks Koepka, with their simmering rivalry one of the more intriguing sub-plots in golf during 2021.

At last month's US PGA Championship, a video of Koepka visibly frustrated at an interruption from DeChambeau went viral, which led to the pair trading back-and-forth jibes on social media.

Prior to the tournament, DeChambeau admitted the two just "don't like each other". On Sunday, as he contemplated going for the par-five 18th in two while in a sand trap, fans of Koepka yelled "go get 'em Brooksy" and "Brooks would go for it".

DeChambeau resisted the temptation to bite but when questioned about it after his round, the world number five insists he is relishing the rivalry.

"Hey, I love it. I think it's so much fun," said DeChambeau, who recorded his first ever bogey-free round in major golf to sit two back of leaders Mackenzie Hughes, Louis Oosthuizen and Russell Henley at three under at Torrey Pines.

"People think that it annoys me. If anything, it just creates a great atmosphere for golf. At first, I didn't really know how to handle it. You're kind of thrown into a situation. 

"But now I enjoy it. I think it's great. You've got to embrace it. There's going to be team Bryson, team Brooks out there, and hey, keep it up, I'm happy about it. 

"I'm excited that one day we can eventually get paired up and play together. It would be fun."

DeChambeau, who scored a three-under 68 in round three, is using driver at almost every opportunity in tactics similar to those he employed when winning at Winged Foot last year.

He says he has learned the nuances of coping with major golf.

"You've got to be really patient out here at these majors. It's something that is not easy to do," he added.

"My first few goes at majors, I was not successful or anywhere near successful, and I feel like I'm starting to understand major championship golf and how to play it and how to go about managing my game, my attitude and just my patience level. 

"If I can continue to do that [on Sunday], I think I'll have a good chance."

Jon Rahm is three off the lead after signing for a one-over 72 on Saturday. The Spaniard thinks being part of the chasing pack may actually play to his strengths.

"I feel like it's easy when you're in the lead to get a little tentative and start trying to be a little bit more safe in certain parts," he said. 

"I feel like when you're a couple shots back, you have nothing to lose early on. So, I feel like you can be a little bit more aggressive and try to get some birdies.

"There will be somebody who gets a fast start, and hopefully that's me tomorrow, and I get a fast start, and I get it going fast."

Since winning The Open in 2010, Oosthuizen has been a perennial nearly man in the majors, recording five runners-up finishes including play-off defeats at the 2012 Masters and 2015 Open, while he was tied second to Phil Mickelson at the PGA Championship last month.

The South African is aiming to take the positives from those experiences, though, saying: "The two that really hurt was the playoffs. That's so close to winning.

"You know, the other ones, just good weeks and good results. Could have been better but taking more positive out of it than anything else."

Oosthuizen drained an eagle at the par-five 18th, which drew a huge reaction from the galleries.

"A year ago, that would have been a very boring eagle with a few people going nuts. But that was nice to see everyone back," he said, alluding to the return of fans who were unable to attend in 2020 due to the coronavirus pandemic.

Ten years to the day after he wrapped up his first major championship win at Congressional, Rory McIlroy put himself in position for another U.S. Open title by shooting 67 Saturday at Torrey Pines. 

McIlroy is three under par for the tournament, two strokes back of the leading trio of Louis Oosthuizen, Mackenzie Hughes and Russell Henley entering Sunday's final round. 

The Northern Irishman will feel good about his chances after a round that featured five birdies and just one bogey a day after he shot a wobbly 73. 

The lone bogey may have been the key to his round, a difficult save that kept him from losing momentum after what had been a positive day. 

"This is the only tournament in the world where you fist pump a bogey," McIlroy told reporters.

"Only losing one there was a big deal, and getting it up-and-down out of the bunker on 16 and making that birdie on 18 just to get that shot back that I lost, really big."

By the end of the day, McIlroy considered it "one of the best rounds of golf I've played in a while." 

The 32-year-old broke an 18-month title drought with his win at the Wells Fargo Championship in May.

He also won that tournament in Charlotte, North Carolina for his first PGA Tour victory six weeks before securing his first major championship a decade ago.

There will be no repeat of that astonishing eight-stroke victory over Jason Day this weekend, but McIlroy is satisfied to be in the hunt for his first major title since the 2014 US PGA Championship. 

"I mean, I'm trying to think of the last time where I really felt like I had a chance [at a major]," he said.

"Carnoustie in '18 felt like I maybe had half a chance, going into the final day at Pebble in 2019.

"But apart from that, there's been some good finishes but never felt like I was in the thick of things.

"I'm just excited for the opportunity to have a chance and be in one of the final groups."

Louis Oosthuizen and Mackenzie Hughes used eagles on the back nine to surge into a share of the lead heading into the final round of the U.S. Open. 

They join Russell Henley atop a crowded leaderboard at Torrey Pines after the second-round co-leader saved par on 18 to complete an up-and-down round and sit at five under par for the tournament. 

Oosthuizen finished with a flourish, draining a downhill putt for eagle on 18 to cap his one-under 70 as he continues the quest for his second major title 11 years after winning the Open Championship. 

The unheralded Hughes, meanwhile, eagled the 13th and birdied the last for a 68 on the day. He is the first Canadian to hold at least a share of the lead after 54 holes of a major since Mike Weir at the 1999 US PGA Championship. 

The 30-year-old missed the cut in his last five PGA Tour starts and has only one career victory, in the 2016 RSM Classic at Sea Island. 

Impressive as Hughes was, the round of the day belonged to Rory McIlroy (67), who also birdied the 18th to reach three under for the tournament exactly 11 years after he closed out his runaway U.S. Open win at Congressional. 

Bryson DeChambeau (68) also lurks two back of the leaders after a bogey-free third round. 

Jon Rahm (72) is among the group at two under as he seeks his first major title, along with 2020 U.S. Open runner-up Matthew Wolff (73) and Scottie Scheffler (70).

The 2016 U.S. Open champion Dustin Johnson (68) is four back of the lead at one under along with 2020 US PGA champion Collin Morikawa (70), Christiaan Bezuidenhout (70), Xander Schauffele (72) and Kevin Streelman (72). 

Among other notables, Brooks Koepka and Justin Thomas are at even par after shooting 71 Saturday, while Jordan Spieth (68), Martin Kaymer (69), Lee Westwood (71) sit one over. 

Richard Bland, who shared the lead with Henley after the second round, plummeted down the leaderboard to one over with a brutal round of 77 punctuated by the 48-year-old putting his approach shot in the water on 18. 

Rory McIlroy and Dustin Johnson kept themselves well within a shout of second respective US Open successes with excellent third rounds on Saturday.

Johnson put in his best performance of this year's event at Torrey Pines, carding a 68 which moved the world number one to one under par, and he would surely have been even closer to the leaders if not for a dismal loss of form on the back nine on Friday.

"I feel like I'm swinging really well. I didn't drive it on the fairway enough but I felt like I managed the game pretty well. I rolled the putter really nicely today and made a lot of clutch par putts, which is what you've got to do in the US Open," Johnson told Sky Sports.

"When I was on the fairway I felt like I played pretty well, my irons were good and I'm controlling my distance – I'm just not getting enough shots from the fairway.

"I felt like they did a really good job of setting the course up - if you drive it on the fairway, you can attack the golf course and it's been like that all week. There's a few holes obviously where you will take a four and run but for the most part the way they set it up today, you can attack it."

McIlroy, meanwhile, went one better, finishing on 67 for the round to keep his chances firmly alive. The 2011 champion's birdie on the 18th ensured he was the clubhouse leader at three under.

Russell Henley, meanwhile, reached the turn with a two-shot lead over Richard Bland.

The overnight leader reached the front of the ninth in two shots, yet missed his eagle attempt and subsequently had to settle for a three-out par, whereas Henley snatched a birdie.

However, Henley then dropped a shot on the 10th, immediately cancelling out his own advantage.

Bryson DeChambeau is also in the hunt, with the defending champion T3 with McIlroy, Jon Rahm and Matthew Wolff.

Paul Casey had looked sharp earlier in the day, yet bogeys on the 16th and 17th meant he had to settle for 67, and heads into round four on par.

Bryson DeChambeau said his swing fix "came to him" in a dream after the U.S. Open champion kept his title defence alive.

DeChambeau opened his bid for back-to-back U.S. Open trophies with a 73 but the big-hitting American responded by posting a two-under-par 69 on Friday.

An eagle, four birdies and four bogeys saw DeChambeau surge 47 positions on day two, moving within five shots of co-leaders Richard Bland and Russell Henley at Torrey Pines.

Reflecting on his bounce-back display heading into the weekend, DeChambeau credited a late-night tweak.

"I was sleeping and it came to me in the middle of the night," DeChambeau told reporters.

"Woke up and I was like, hmm, I'm going to try this, and my intuition is pretty good, so I went out and tried it and it worked, just keeping the right wrist bent for a lot longer through impact."

"It's more just my intuition telling me there's something weird here, what's going on, and I couldn't figure it out for an hour and a half last night, an hour last night," said DeChambeau said. "Going back and just sitting down, eating dinner and just thinking about it, thinking about it, I literally won't talk to anybody for like an hour, just thinking, thinking, thinking, and sure enough, I went to bed and I found a little something that worked for my driver."

DeChambeau added: "I feel like if I can clean up my iron play and get a little more comfortable with the irons and the drivers, I'll have a good chance for this weekend."

He is tied for 13th alongside the likes of rival Brooks Koepka (73), Justin Thomas (69) and Collin Morikawa (67).

Amid their ongoing feud, DeChambeau and two-time U.S. Open champion Koepka narrowly avoided being paired together for Saturday's penultimate round.

Koepka – eyeing a fifth major crown – lost ground on the leaders after mixing five bogeys and just three birdies but he told reporters: "I feel right there. I feel like I'm in it. Just need to put two solid good rounds and put the ball in the fairway, and that's it. I love the way I'm putting. I love the way I'm striking it. Just need to keep doing it."

Four-time major winner and former world number one Rory McIlroy is a stroke further back following his second-round 73.

"A bit of a rollercoaster, got off to a good start," McIlroy said. "Made a couple of birdies early on and was under par for the round. Then I made a couple of mental errors and missed it in the wrong spots, and when you do that around this golf course, it's just really hard to see a par.

"I made a few bogeys, but birdieing two of the last four holes definitely makes me feel better about the round and gives me a nice bit of momentum going into tomorrow…So, yeah, in for the weekend and still feel like I've got a really good chance."

US PGA Championship winner Phil Mickelson also feels he can "make a run at it" after avoiding the cut on Friday.
