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.

Spectators soaked up the sunshine on another glorious day at Royal St George's as The Open Championship's third round left us poised for a thrilling finale.

On the course it looks set to be a final-day shoot-out between three major champions, with Louis Oosthuizen, Collin Morikawa and Jordan Spieth setting the pace.

Meanwhile, there was plenty happening on the other side of the ropes as fans lapped up the entertainment on offer.

Our man on the ground brings you all the latest after being out and about on the Kent links on Saturday...

CELEBRITY SPOTTING

Big sporting events tend to attract stars from all manner of show business backgrounds, and it seems stand-up comedians are not immune to the allure of a golf major.

As this reporter was roaming alongside the 18th fairway he heard a familiar voice asking where the official Open shop was.

"It's the big building over there with 'the shop' written on it," I said.

"You're very helpful, thank you," replied British comedian Michael McIntyre.

PLAN OF ACTION 

As a spectator at a golf event, you have a multitude of options: pick a spot and make it your own for the day; follow a particular group; or maybe just wander around and see what you see.

One cluster of fans who had only just arrived were gathered around a course map, each apparently with very different ideas about what to do.

In such situations, it takes a leader to sort things out and, luckily for this group, the best man for the job stepped forward.

"Why don't you argue about this from somewhere you can actually see the golf?" he said, ushering the group away from the entrance.

WESTWOOD GRAFTING

Away from the gaze of the cameras and long after his round of 70 had come to a close with a birdie at the 18th, Lee Westwood was putting in the hard yards on the practice range.

The Englishman was one of a handful of players grafting away in the evening sun as, even at the age of 48, he showed every day presents an opportunity to learn and improve.

That's the commitment it takes to succeed!

Louis Oosthuizen will take a one-shot lead into the final round of The Open, where two fellow major winners are his closest rivals.

The 2010 champion will go out in the final group at Royal St George's on Sunday, when he will have 2020 US PGA Championship winner Collin Morikawa for company.

Oosthuizen, who sits at 12 under and is chasing a wire-to-wire triumph, has had two runner-up finishes in majors this year, taking his career tally to six.

Also in the mix is Jordan Spieth, who claimed the Claret Jug in 2017, but the American's third round finished with back-to-back bogeys to leave him three adrift.

Corey Conners and Scottie Scheffler, both in search of maiden majors, are poised at eight under.

Pre-tournament favourite and U.S. Open champion Jon Rahm cannot be discounted at seven under, a score matched by Oosthuizen's fellow South African Dylan Frittelli.

Rory McIlroy threatened to get involved at the top end of the leaderboard after making the turn in 31, but three back-nine bogeys ended his hopes, while reigning champion Shane Lowry closed on five under.

It was a day to forget for world number one Dustin Johnson, whose 73 left him eight strokes adrift.

SHOT OF THE DAY

Danny Willett may ultimately have given back the two shots he gained with his hole-out eagle on the par-four 10th, but it was still a glorious shot.

The 2016 Masters champion was six under overall at that point and could scarcely believe what he had done.

CHIPPING IN

Rory McIlroy: "Sort of a tale of two nines. I played great on the front nine, hit some really good iron shots and converted some putts and really got it going. Then the back nine played tough."

Shane Lowry: "I have mixed emotions, to be honest, because I played great. I left a lot of shots out there."

Danny Willett: "It's always a bonus when they go in when you haven't holed a shot for a hell of a long time."

A LITTLE BIRDIE TOLD ME...

- The 14th was the most generous hole as the par five played at an average of 4.53.

- McIlroy's five birdies was his best return from his first nine holes at an Open.

- Conners hit 92.86 per cent of fairways in his four-under 66.

Louis Oosthuizen and Jordan Spieth will each continue their bids for a second Open Championship title amid fierce pressure at Royal St George's on Saturday.

The Kent links was once again bathed in sunshine as the 149th edition of golf's oldest major returned for the third round in Sandwich.

Firmer greens and tougher pin positions made life a little harder but the course still seemed nicely set up for low scoring, with Oosthuizen's 129 the lowest overall tally at the halfway stage of an Open.

The South African slept on a two-shot lead over Collin Morikawa and the 2010 Open champion will tee off alongside the 2020 US PGA Championship winner at 15:55 local time. 

Oosthuizen has been remarkably consistent in majors since his Open triumph 11 years ago, finishing as runner-up an incredible six times.

Spieth, who claimed the Claret Jug in 2017 and is eight under, goes out with Oosthuizen's compatriot Dylan Frittelli in the penultimate group.

Rory McIlroy looked to be making a charge when he made the turn in 31, but three bogeys on the back nine meant he signed for a 69 and well out of the picture.

World number one Dustin Johnson will get a couple of holes in before the leader gets his third round up and running, with the American starting four shots back.

With pre-tournament favourite Jon Rahm moving to five under overall through three holes, the Spaniard is still in the mix, but reigning champion Shane Lowry's bogey at the fourth left him adrift.

Louis Oosthuizen did not realise he had broken an Open Championship record until he got off the course at Royal St George's on Friday.

The South African carded a 65 to move to 11 under, with his overall score of 129 the lowest after 36 holes at golf's oldest major.

It left the 2010 Champion Golfer of the Year two strokes clear of Collin Morikawa, with Jordan Spieth one stroke further back.

But Oosthuizen, who has finished second in two majors already this year, had no idea he had just made history when he sunk a par putt at the last.

"I only heard that when I walked in, so I wasn't aware of what it even was before," he conceded after fine conditions made the Kent links ripe for low scoring, with playing partners Jon Rahm and Shane Lowry shooting 64 and 65 respectively.

"To have any record at the Open or part of any record at the Open is always very special.

"I think I've played really good the last two days. It was as good a weather as you can get playing this golf course. All of us took advantage of that.

"I think in our three-ball we had a 64 and two 65s, which you don't really see around a links golf course."

The 38-year-old has had a succession of close calls since he claimed the Claret Jug at St Andrews 11 years ago, with a remarkable six runner-up spots in majors.

Asked if there was an issue with getting it over the line, he replied: "I don't know. I think in a few of them I needed to play just that little bit better coming down the stretch.

"It's just I don't think I would have done a lot different in a lot of them.

"Right now I think where my game is at, I just need to put myself in position, and this year is the best I've been putting, and I just need to hit greens and give myself opportunities for birdies."

It was moving day at The Open Championship on Friday but the sunshine refused to budge.

While Louis Oosthuizen recovered the overnight lead that he had lost to Collin Morikawa earlier in the day, a few fans' favourites ensured they will be around at the weekend.

Rory McIlroy and Shane Lowry both did enough to make the cut and world number one Dustin Johnson surged up the leaderboard.

But our man on the ground also had an eye on events on the fringes of the action...

BUTTER FINGERS!

When the players walk off the 18th green they pass under the grandstand that surrounds the putting surface.

Above them will often be a gaggle of fans trying to get their attention so they might throw a golf ball their way.

But when that chance comes you have to be ready to take it, and one young fan's hopes were dashed when Tommy Fleetwood tossed a ball within his grasp but he let it slip.

When a marshal picked it up to throw it back to the waiting fans, it was a different young hopeful who managed to seize the opportunity.

MERRY CHRISTMAS?

Lucas Herbert's caddie had fans in a festive mood, despite it being the middle of July.

Nick Pugh sports a bushy white beard and, as he made his way from the 15th green to the 16th tee, one cheeky fan asked if the jovial Scot had received his Christmas list.

Pugh saw the funny side and retorted: "Ho ho ho!"

BEERY ME...

They are not compulsory, but some spectators are choosing to wear face masks in these coronavirus times.

That is all well and good, but it's important to remove your mask before attempting to drink your beer.

One fan probably won't need to learn that lesson again after inducing much mirth following a botched attempt to take a swig from his pint with his face mouth covered.

Louis Oosthuizen holds a two-shot lead at the halfway stage of the 149th Open Championship after posting a record 36-hole score at golf's oldest major.

The South African, who claimed the Claret Jug in 2010, continued his stunning form at majors in 2021 with a 65 on Friday, with 129 the lowest total after two rounds at this event.

Tournament debutant Collin Morikawa, who had earlier carded a 64 at a sun-drenched Royal St George's, is Oosthuizen's closest rival on nine under, with 2017 winner Jordan Spieth one stroke further back.

Oosthuizen finished in a tie for second at the US PGA Championship in May and was outright runner-up at the U.S. Open the following month. 

He faces stiff competition from a chasing pack that also includes world number one Dustin Johnson following his 65 to move seven under, while Brooks Koepka is on five under.

Favourable weather on the Kent coast meant the course was set fair for low scoring and 2020 US PGA Championship winner Morikawa took full advantage.

His round included a run of five birdies in seven holes before a bogey at the 15th – the tricky par four playing at an average of 4.4 – halted his progress.

Oosthuizen did not go out until the afternoon but quickly made his intentions clear with a birdie at the first, though the highlight of his round was an eagle three at the 14th.

Reigning champion Shane Lowry also enjoyed a fine day as he shot 65, while pre-tournament favourite Jon Rahm went one better to keep his slim hopes alive.

Rory McIlroy birdied the last to ease any lingering fears of missing the cut, while 2018 champion Francesco Molinari did not make the weekend after a 74 that included a quadruple-bogey seven at the sixth, where he took three shots to get out of a bunker.

SHOT OF THE DAY

There was joy for Englishman Jonathan Thomson as he hit the first ace at the 16th en route to a 67.

CHIPPING IN

Rory McIlroy: "I felt a little nervous going to that 18th tee. I knew I needed a par at least, but birdie to at least be comfortable."

Jonathan Thomson: "The hole-in-one was obviously awesome. It was a real confidence booster after what had been up until that point a real grind."

A LITTLE BIRDIE TOLD ME...

- Jordan Spieth's halfway score of 132 is the American's second lowest at a major.

- Emiliano Grillo shot a 64, which was six strokes better than his opening round.

- Phil Mickelson improved on his opening effort by eight strokes, but still missed the cut at 12 over.

Collin Morikawa feels has the right mindset to cope with the pressure of majors after he took the lead at the Open on Friday with a fine 64.

The debutant surged up the leaderboard with a tremendous second round, moving to nine under for the tournament.

A stunning card from the 2020 US PGA Championship winner showed just one bogey and he could have even moved further clear had a putt on 18 not skirted the cup.

Morikawa made seven birdies as he took advantage of fine early conditions at Royal St George's.

As well as his US PGA win, Morikawa, 24, also has a 2021 top-10 finish to his name at that tournament, as well as coming fourth at the U.S. Open last month.

"Yeah, I look at them as obviously they're starred," he said of his success at majors so early in his career.

"We have four of them a year, and you're trying to definitely win these four because they're that big. 

"Talking about last year's PGA, I had seen every single guy before, I had played with every single guy, and that doesn't make anything different. 

"It's just the stage that we're on, more media, more spectators, more people around. 

"But that's everything outside that I could control. For me, it's just let's go figure out this golf course Monday through Wednesday like I have been the past couple years and figure it out on what I need to do to play well. 

"This style of golf is very different, but playing last week at the Scottish Open helped tremendously."

Morikawa posted a 67 in round one but believes his play was similar across the first two days.

"Just sticking to what I've been doing," he said of his Friday success.

"On Thursday I thought I played really well, just wasn't hitting as many fairways. Was able to hit a few more fairways early on in the round this time."

Morikawa ended his round three clear of overnight leader Louis Oosthuizen, who was joined at six under by fellow South African Daniel van Tonder as well as Emiliano Grillo, Marcel Siem and Jordan Spieth.

A flying start from former champion Spieth, who birdied his first two holes on Friday, meant he was promptly up to seven under and within two of his American compatriot, though he then dropped a shot at the third.

Birdies on 17 and 18 meant Grillo matched Morikawa with a 64, while Siem also gained two shots in the final two holes to sign for an impressive 67.

Rory McIlroy, meanwhile, all but ensured he will finish above the cut line with a crucial birdie on 18.

The Northern Irishman is level par for the week after a second straight 70. 

In an up-and-down round two, he recovered nicely from consecutive bogeys to start his day but then bogeyed 16 and 17 before improving his position once more at the last.

Tournament debutant Collin Morikawa surged into the lead at The Open with a second-round 64 to move to nine under on Friday.

The 2020 US PGA Championship winner's stunning card showed just one bogey as the American ended his round three clear of overnight leader Louis Oosthuizen.

Morikawa made seven birdies as he took advantage of fine conditions at Royal St George's, but he squandered the chance to get to 10 under with a putt on 18 that skirted the cup.

Daniel van Tonder moved level with South African compatriot Oosthuizen following a 66, while Tony Finau signed for the same score to get to four under.

Rory McIlroy, who matched Finau's 70 on Thursday, remained at even par through 11, while 2018 Champion Golfer of the Year Francesco Molinari is unlikely to make the weekend after a 74 left him two over.

Oosthuizen goes out at 14:59 local time alongside reigning champion Shane Lowry and pre-tournament favourite Jon Rahm, both of whom will be looking to improve on rounds of 71.

The 149th Open Championship got under way at Royal St George's on Thursday, with Jon Rahm the hot favourite to prevail.

Englishman Richard Bland, who won his first European Tour title on his 478th start at the British Open in May, had the honour of teeing off proceedings at 06:35 local time at the Kent links, which is hosting for the 15th time.

Rahm claimed his maiden major with victory at this year's U.S. Open and will attempt to wrestle the Claret Jug from the grasp of playing partner Shane Lowry, with 2010 Champion Golfer of the Year Louis Oosthuizen completing a trio that tees off at 09:58.

Lowry, who is aiming to become the first player to successfully defend the prize at this course since Harry Vardon in 1899, proved a popular winner at Royal Portrush two years ago, with the 2020 event having been cancelled amid the coronavirus pandemic.

Spaniard Rahm is eyeing a rare double, with only six players having won the U.S. Open and Open Championship in the same year.

The omens bode well for the in-form Jordan Spieth after he was drawn alongside Bryson DeChambeau and good-luck charm Branden Grace.

Grace 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. 

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, goes out at 08:25 alongside Bernd Wiesberger and amateur Joe Long.

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."

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.

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.

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.
