A year after withdrawing before the start of the US PGA Championship following hand surgery, Bryson DeChambeau set the clubhouse target on a weather-delayed opening day at Oak Hill.

DeChambeau carded six birdies and two bogeys in an opening four-under-par 66 on a course that lived up to comparisons with Winged Foot, the venue for his dominant US Open victory in 2020.

Much has happened to the 29-year-old since then, including a feud with Brooks Koepka, being labelled an eight-year-old by his equipment manufacturer after complaining his driver “sucks” during the Open Championship and abandoning his unhealthy bulking regime.

DeChambeau also joined LIV Golf last year, five months after pledging his loyalty to the PGA Tour, while Thursday’s round included accidentally hitting fellow competitor Kenny Pigman – who was on the 18th tee – with a wild approach to the 17th.

“It’s a fantastic round of golf at Oak Hill,” DeChambeau said. “It’s a prestigious place. Very difficult golf course.

“As I was looking at it throughout the week, I’m like, man, I don’t know how shooting under par is even possible out here on some of the golf holes.

“But, luckily, I was able to play some really good golf, hit a lot of fairways, did my job and made some putts.

“It’s a different test (to Winged Foot) and a test that I’m willing take on. If you’re driving it well and hitting your irons well, you can play out here, but it can get pretty nasty pretty quick if you’re not hitting it straight.”

A combination of injuries, loss of form and joining LIV Golf – which cannot award world ranking points for its events – means DeChambeau has fallen from a career-high of fourth in the standings to 214th.

And he admitted there were times when he doubted whether he would ever be able to get back to the top of the game.

“How serious were they? There were times I doubted myself, severe doubts, but never got to a point where I was done. Maybe for like a day I was done, I’m just going to take a day off, whatever, and the next day I came back.

“The emotions have definitely fluctuated pretty high and pretty low, thinking I have something and it fails and going back and forth.

“It’s humbling. Golf, and life, always has a good way of kicking you on your you-know-what when you are on your high horse. It’s nice to feel this today.”

Daniil Medvedev and Stefanos Tsitsipas will clash in the semi-finals of the Italian Open in Rome.

Both eased through their quarter-finals on Thursday, with third seed Medvedev, who had never won a match at the Foro Italico prior to the start of the tournament, ending the run of qualifier Yannick Hanfmann with a 6-2 6-2 victory.

“I remember sitting here before the tournament and saying how good I felt in practice,” the Russian told reporters in the Italian capital.

“It’s always tricky because then you can lose first round against a great opponent and you’re going to be like, ‘Yeah, well, why did I say this? Better shut up.’ That’s how I felt. I’m happy I managed to transfer this onto the tennis court.”

Tsitsipas had to wait until the night session to take on Borna Coric, and the Greek produced a fine display to see off the 15th seed 6-3 6-4.

It will be a 12th meeting between regular rivals Tsitsipas and Medvedev. Medvedev leads 7-4 but Tsitsipas has won the last two and also beat the Russian at the French Open two years ago.

A vote to approve the record sale agreement of the Washington Commanders will not take place next week at the NFL's owners meetings.

NFL executive vice president Jeff Miller told reporters in a conference call the league will provide an update on the proposed ownership change at next week's meetings in Minneapolis, though a formal vote for approval will take place at a later time.

Earlier this month, embattled owner Dan Snyder agreed to sell the Commanders to a group led by Philadelphia 76ers and New Jersey Devils owner Josh Harris for $6.05 billion, the largest purchase price for a professional sports franchise in North America.

"The league staff and finance committee will continue to review the details of the transaction," Miller said on Thursday. "We will provide membership with an update in Minnesota."

The Harris group, which includes NBA Hall of Famer Magic Johnson, contains multiple limited partners which must be vetted by the NFL before a vote can proceed. The sale will require the approval of 24 of the league's 32 owners to become official.

"Any transaction like this deserves due process, and we will do it as expeditiously as we can. [We have] plenty of people working on it, and doing so is a priority," Miller added.

Snyder and his wife, Tanya, announced in November they would be putting the historic franchise up for sale following a congressional investigation into allegations of workplace misconduct and financial misdeeds.

The NFL launched an additional probe headed by former U.S. Attorney Mary Jo White, which is still ongoing.

The Snyder family purchased the Commanders, then known as the Redskins, from the estate of Jack Kent Cooke in 1999. After years of opposing changing the team's controversial nickname, Snyder finally relented in 2020 amid heavy pressure from activist groups and corporate sponsors.

Rory McIlroy battled illness and a poor start to remain in contention for a third US PGA title as Bryson DeChambeau set the clubhouse target at Oak Hill.

On a course which has drawn comparisons to Winged Foot, the venue for his US Open triumph in 2020, a slimmed-down DeChambeau still possessed enough power to post six birdies and two bogeys in an opening 66.

That gave DeChambeau a one-shot lead over world number two Scottie Scheffler and Corey Conners, with Viktor Hovland, Ryan Fox and Keegan Bradley on two under par.

McIlroy fought back from three over par after nine holes to return a 71, while Masters champion and world number one Jon Rahm surprisingly slumped to a six-over-par 76.

Following a delay of almost two hours due to overnight frost, Oak Hill member McIlroy had started from the 10th hole with five straight pars before badly mishitting his tee shot on the 15th to find a bunker 30 yards short of the pin.

McIlroy hit a good bunker shot to nine feet but was unable to convert the par putt and also failed to get up and down from sand on the 17th, before taking a swipe at the tee marker on the 18th following an errant drive.

The four-time major winner looked certain to drop another shot after firing his third to the second over the green, but holed from 35 feet up a steep slope for an unlikely par and then hit a brilliant tee shot to two feet on the next.

“It was massive,” McIlroy said. “I was sort of just hoping to get down in two and make bogey and go to the third hole at four over par.

“When you walk off the green three over and then you hit a tee shot like that, all of a sudden the pendulum swings or momentum goes the other way and you feel like you’re right back in the tournament.

“Depending on what happens over the next three days and what I go on to do, I may look back at that shot as being the sort of turning point of the week.”

McIlroy reduced the 617-yard fourth hole to a drive and long iron to set up his second birdie of the day and although he three-putted the next, a birdie on the eighth helped complete a battling round despite being under the weather.

“I’m fighting something,” McIlroy confirmed.

“I thought I got a great night’s sleep last night and I looked at my Whoop (personal fitness monitor) and I was 22 per cent recovery, and my skin temperature was 3.5 degrees higher than what it’s been.

“But I actually feel better today than I felt yesterday, so plenty of water and a bit of rest, I’ll be fine.”

Rahm had started his day with a birdie on the 10th, his opening hole, but dropped five shots in six holes around the turn and also made a double bogey on the seventh.

“Obviously the first six holes of the day I played really good,” Rahm said.

“Put myself in a good spot and after that I found myself battling. Couldn’t find the fairway and the fairways that I missed cost me bogeys.”

Play had been scheduled to get under way at 7am local time (1200 BST), but predictions of cold conditions overnight proved accurate and led to tee times being delayed by an hour and 50 minutes.

The possibility of weather delays had been on the cards since the US PGA was moved from August to May in 2019, with Oak Hill having already been selected as this year’s venue.

Callum Wilson and Bruno Guimaraes served up a grandstand finish to take Newcastle to the brink of Champions League football with a resounding victory over Brighton.

Having seen Deniz Undav drag the Seagulls back into the game after his own goal and Dan Burn’s towering header had given the Magpies a 2-0 half-time lead, Wilson scored his 18th of the season and then set up Guimaraes to wrap up a 4-1 win at the death in front of a delirious crowd of 52,122 at St James’ Park.

Eddie Howe’s men will be assured of a top-four finish if Liverpool lose to Aston Villa on Saturday – even a draw might ultimately prove enough as a result of their superior goal difference – but can complete the job themselves in any case if they beat struggling Leicester on Tyneside on Monday evening.

For much of the game, this was not the Brighton which effectively ended Arsenal’s title challenge on Sunday, partly because of the absence of Levi Colwill, Alexis Mac Allister, Julio Enciso and Evan Ferguson from the starting line-up, but largely as a result of the relentless pressure exerted by their opponents.

Joe Willock saw an early cross hacked away to Miguel Almiron, whose shot was blocked at source as the Magpies found their rhythm, and Fabian Schar drilled a ninth-minute free-kick straight at the grateful Jason Steele.

Willock fired just wide from Almiron’s pull-back seconds later, and the Paraguay international cleared the target by some distance from a tight angle after the former Arsenal midfielder had returned the favour.

Such was the Magpies’ early intensity that the Seagulls were struggling to play their way out of their own half, much to manager Roberto De Zerbi’s agitation, although keeper Nick Pope was tested for the first time by Danny Welbeck’s 16th-minute attempt after Kaoru Mitoma had picked him out.

But the pressure finally told with 23 minutes gone when Trippier drilled the latest of a series of corners to the near post and in his attempt to clear it, Undav could only glance the ball into his own net.

Burn saw a sharply-executed 34th-minute shot on the turn deflected wide after the visitors failed to deal with another Trippier corner and although Mitoma chanced his arm with an ambitious 37th-minute strike which failed to engage Pope, Newcastle extended their lead deep into added time.

With Joelinton still seething at a Moises Caicedo challenge which went unpunished by referee Robert Jones, Tripper took full advantage of a decision which did go his side’s way seconds later, curling a free-kick on to the head of Burn, who powered it past the helpless Steele.

Almiron passed up a chance to put the game beyond the visitors within five minutes of the restart when he shot straight at Steele from Willock’s knock-down, and the miss proved costly within seconds when Undav ran on to Billy Gilmour’s through-ball and beat Pope to make amends for his earlier contribution.

Mac Allister, Enciso and Ferguson were swiftly thrown into the mix and just as quickly, Willock departed clutching his hamstring and Elliot Anderson joined the fray.

But there was no let-up as the home side saw penalty appeals waved away after Burn appeared to have his shirt tugged and Steele made a superb save to keep out Alexander Isak’s header.

Enciso glanced Caicedo’s cross wide of Pope’s far post as the game became increasingly open, but the Magpies launched a devastating late assault to wrap up the win.

Wilson added a third when he rounded off an 89th-minute counter-attack sparked by Almiron before setting up Guimaraes to make it 4-1 in injury-time.

New Zealand’s Ryan Fox admitted his impressive opening round came as a surprise after detailing his extraordinary build up to the 105th US PGA Championship.

Fox fell ill during his Masters debut last month and withdrew after just nine holes of the following week’s RBC Heritage before flying home to Auckland.

The 36-year-old was diagnosed with pneumonia and took two weeks to recover, just in time to welcome the arrival of his second daughter Margot.

After enjoying a few days at home with his family, Fox then flew back to the United States and only arrived in Rochester on Monday morning, before also having to deal with an overnight frost which delayed Thursday’s early starters.

“It’s been an interesting last month,” Fox, who won twice on the DP World Tour last season, said with considerable understatement after carding a two-under-par 68.

“At the Masters I was pretty sick on the weekend. Tried to play Hilton Head, withdrew from there after nine holes, just feeling awful. Got home and got told I caught pneumonia, which pretty much explained why I felt so bad.

“Basically as soon as I got over that, our daughter was born, which was just over two weeks ago now. So I had a few sleepless nights and not a lot of practice.

“One of the days I was supposed to go to practice, Auckland flooded for the third time this year. So I think I drove around Auckland (covering) 27 kilometres in four hours in chaos.

“It wasn’t quite the ideal preparation for a major, but I was kind of hoping the fact I needed a break after a busy start to the year and being mentally fresh would have been important this week.

“It’s pretty surprising to have four weeks off and shoot 68, especially when the course is pretty brutal if you are out of position.”

As one of the early starters Fox left his hotel at 5.30am, meaning he only received notification of the delayed start when he arrived at the course.

“I was due to see my physio at 6am and I was going to have breakfast beforehand. Just as I got to the golf course, I got the text,” Fox added.

“I certainly would have liked another hour and a bit in bed, but I can go and have a pretty nice nap this afternoon, I think.”

Jurgen Klopp’s poor disciplinary record and his failure to heed previous conduct warnings were aggravating factors which led to the Liverpool manager receiving a two-match touchline ban for implying bias by referee Paul Tierney.

Klopp was fined £75,000 and will not be in the technical area for their final Premier League home game of the campaign against Aston Villa on Saturday but the second match of his punishment has been suspended until the end of next season.

The German admitted a charge of improper conduct in that his comments about Tierney implied bias, questioned the integrity of the referee and brought the game into disrepute.

Klopp, who was booked for celebrating in the face of fourth official John Brooks after Diogo Jota’s added-time goal in the 4-3 win over Tottenham last month, suggested in post-match interviews what Tierney had said to him in issuing the caution was “not OK” and went on to add “we have our story, history, with Mr Tierney. I really don’t know what this man has with us”.

The independent disciplinary commission, in its written reasons, said the Professional Game Match Officials Limited viewed Klopp’s comments as an “unwarranted attack on Mr Tierney’s integrity” and so immediately issued a statement in defence of the official.

Klopp later apologised, clarifying his words and denying he had questioned Tierney’s integrity and while that, and his letter to the commission, were deemed “considerable mitigation” it was his history which counted against him.

“Mr Klopp has a poor record for disciplinary offences, having appeared before commissions on three occasions in the past five years,” said the commission in its written reasons.

“In November 2022 in an appeal in which two members of the present commission sat, Mr Klopp received a touchline ban, a fine and a warning.

“Those sanctions plainly failed to deter Mr Klopp from committing nine similar breaches of the rules. Mr Klopp is a high-profile individual in the football world. He must have known that what he said would attract widespread publicity.

“He should have realised that it was incumbent on him to restrain himself and to behave properly.

“The statements that Mr Klopp made/adopted were not limited to comments on the immediate match, but extended to allegations of persistent bias against a blameless referee.

“The intense media interest that followed Mr Klopp’s remarks was highly damaging.”

Klopp created a problem for himself when he charged down the touchline following Jota’s goal after Tottenham’s 90th-minute equaliser had cancelled out Liverpool’s earlier 3-0 lead.

From evidence obtained from the officials’ audio, Brooks told Tierney “Jurgen Klopp has just run and celebrated in my face. I think it’s a yellow card mate, minimum”.

VAR backed up Brooks’ opinion and in booking Klopp, Tierney said: “I have to show you yellow… it could be red, but I am going to show you yellow. We will give you the benefit of the doubt, don’t do anything more.”

Those were the comments Klopp deemed “not OK” but it was not his behaviour on the pitch which produced the disciplinary charge but the aspersions he cast at Tierney, which he subsequently withdrew in a press conference a couple of days later and in a letter of apology to the commission.

Liverpool, in their own letter, stressed Klopp may have misunderstood Tierney and “they do not believe that Mr Tierney purposely gives decisions against LFC and that any suggestion that Mr Tierney was biased or not wholly impartial was totally unintended.

“Mr Klopp did not wish to suggest that Mr Tierney was dishonest, just that there were a long list of key decisions which he felt aggrieved by that have involved Mr Tierney.

“Both LFC and Jurgen Klopp regret that his comments have become a story in themselves and that there has been any question mark cast over Mr Tierney’s impartiality – that was not intended.”

Klopp spelled out his regret in his own letter, saying: “Although it was not my intention I accept now it appears that I was questioning Mr Tierney’s integrity. I take ownership of this. On reflection, the words I used were inappropriate.

“To be absolutely clear, I know that Mr Tierney, along with all other officials, do their work without any pre-conceived bias or prejudice.

“Although not an excuse, I believe we have made up a high percentage of Mr Tierney’s matches this season? Something in the region of 20 per cent of the matches he has officiated have involved my team.

“I do not offer this as a defence, rather it is an observation and could be a reason for both the build-up of frustration governed by an inadvertent accumulation of incidents over an extended period.”

Tom Curry believes rugby should act to prevent the type of injury that has ended the World Cup aspirations of his twin brother Ben.

Ben has been ruled out of Sale’s first Gallagher Premiership final since 2006 after sustaining a serious hamstring injury in Sunday’s semi-final victory over Leicester.

The 24-year-old needs surgery that entails four to six months of recovery, all but ruling him out of the World Cup with England’s opener taking place against Argentina on September 9.

It is a savage blow given his breakthrough international season produced four appearances in the Six Nations.

A post shared by Ben Curry (@bencurry98)

He was contesting the ball on the ground when he was twisted away by Leicester in a manoeuvre known as a ‘crocodile roll’, a controversial breakdown technique which has the capacity to cause significant injuries.

England flanker Jack Willis was sidelined for a year after being rolled out of a ruck against Italy in the 2021 Six Nations and there have been calls for this occupational hazard for back rows to be outlawed.

“If there was something to prevent that (crocodile roll), it would be nice. I think we’ve got to that point now,” Tom said.

“This doesn’t have to be a big thing. It’s just a conversation. But we’re seeing injuries at the breakdown from that and you’ve got to start listening to what’s happening.

“For me, ultimately we’re out there to play the game and if there’s something that’s going to make it safer for people going for the ball then brilliant. But for me rugby is brilliant the way it is and I’ll leave it at that.”

Ben’s rehabilitation has already begun and Tom believes the absence of one of Sale’s most effective performers will drive the Sharks on against Saracens at Twickenham on Saturday week.

“Ben’s a bit less sore now. Because of the type of person he is, he hasn’t really left the training ground. He’s been in a hyperbaric chamber for about five hours for treatment,” Tom said.

“It’s tough because if there’s someone who deserves to play in a final I think it’s him. It’s going to give us an edge. It has to.

“I’m sure he’ll return as the fittest, best person to have back from a hamstring that’s ever happened.”

Aston Villa boss Unai Emery is “optimistic” his side’s charge for European football next season will prove successful.

Villa’s 2-1 win against Tottenham last week lifted them level with the Londoners, who sit seventh in the Europa Conference League play-off place, and to within a point of Brighton, who occupy the last Europa League spot.

Emery, whose side play at Liverpool on Saturday, told a press conference: “After the match against Tottenham, I am optimistic. It’s not in our hands, but we are going to play and try to win.”

Villa responded to recent back-to-back league defeats with victory against struggling Tottenham, their 14th top-flight win in 23 games since Emery took charge last October.

That run has seen the former Arsenal boss nominated for Premier League manager of the season.

Two games remain for Emery’s side – they are at home to Brighton on the final day – and their transformation under the Spaniard has brought a possible top-seven finish into sharp focus.

“I love Europe,” Emery said: “I really want to play Europe because after 15 years, spending a lot of time playing amazing matches, amazing performances and amazing matches, I am here to try and do the same with Aston Villa.”

The 51-year-old is the Europa League’s most successful manager, winning the competition three times with Sevilla and once with Villarreal, while he was a runner-up with Arsenal when they lost to Chelsea in the 2019 final.

“My focus, my passion, is to play here feeling strong emotions together, firstly in the Premier League, secondly trying to be close to trophies and then playing in Europe,” Emery said.

“That is my motivation every day. It’s the reason we have to be focused and, involving the people around us, thinking about football and the possibilities in our life.”

Emery revealed midfielder Philippe Coutinho will play no part in Villa’s last two games after sustaining an unspecified injury in training before the Tottenham match.

Emery added: “I talked with him this week. He’s a little bit unlucky with his month because I didn’t see him play matches like I want.

“But, of course, with the injuries coming, we have to be patient as well, now we are going to wait for his recovery.

“This year, he’s not going to play again until the end of this season because we are finishing in two weeks.”

Defender Calum Chambers missed training on Thursday due to illness, but is expected to be included in the squad for the trip to Anfield.

Lucas Moura will leave Tottenham at the end of the season.

The Brazilian forward has struggled for fitness and form this campaign with no goals in his 17 appearances.

Moura missed a large chunk of the first half of the campaign with a tendon injury and since his return after the World Cup has been involved in several difficult moments for Spurs, being sent off in a 1-1 draw at Everton before his error resulted in Liverpool scoring a stoppage-time winner last month.

Arguably his best moment in a Spurs shirt was when he netted a hat-trick in 2019 at Ajax that sent Tottenham through to a first Champions League final in the most dramatic fashion.

Spurs have now confirmed this term will be Moura’s last and he will get the chance to bid farewell to the Tottenham Hotspur Stadium faithful in Saturday’s home match with Brentford.

“Wherever I am, my heart will always be here. You are my club,” Moura said on Tottenham’s official Twitter feed.

“It has been the greatest honour to defend this badge. Every flick, every tackle, every leap, every goal.

“From the highest of highs to the lowest lows, from the beginning to the end, you sung my name. This has been my dream.

“This will always be my home. Some nights we will never forget, writing history together. I will always love you no matter where I go. We will meet again.”

Moura has scored 38 goals in 219 appearances since he moved to Tottenham in the winter transfer window of 2018.

“We would like to thank Lucas for his tremendous service to our club and wish him the very best for the future,” an official club statement read.

“We shall provide a further update on our wider released and retained player list following the conclusion of the 2022/23 campaign.”

Cuban Thunder looks another Royal Ascot-bound juvenile for Amo Racing having won the Frank Whittle Partnership EBFstallions.com Maiden Stakes at York.

The Profitable colt was second on his debut at the Craven meeting to James Tate’s Blue Storm and the third, Hugo Palmer’s Hackman, came out and won well at Chester.

Sent off a heavily backed 5-4 favourite, Dominic Ffrench Davis’ youngster had to battle hard to gain the upper hand but eventually saw off a pair of newcomers in Charlie Appleby’s Impressive Act and Kevin Ryan’s We Never Stop by two lengths and a head.

The winner earned a 25-1 quote for the Coventry Stakes with Paddy Power, a race for which Kevin Stott looks likely to have the choice of a few.

Ffrench Davis said: “He ran a blinder at Newmarket and he’s such a laid back individual he was half-asleep that day.

“Today he was very different and I did think York might do that to him as they have to walk over the track and can get a little bit on their toes. I knew he’d cope with it, but he got a little bit warm.

“He was very professional in the race. Halfway through he switched off and Kevin wondered how well he was going, but he asked him to quicken and he was straight back on the bridle.

“He’ll get seven furlongs and he’s a lovely horse going forward. The team will have to decide about Royal Ascot, but he’d have to be in mind for the Coventry if there was bit of juice in the ground.”

Croupier (7-1) will head for the Hunt Cup at Royal Ascot after putting a disappointing effort in the Lincoln well behind him when clinging on to win the Sky Bet Hambleton Handicap.

Simon and Ed Crisford’s four-year-old had got bogged down at Doncaster but was much more at home on ground which was quickening up all the time.

William Buick arrived on the inside travelling well at the two-furlong marker but was all out in the end to hold off Point Lynas and Thirsk Hunt Cup winner Northern Express by a head and a nose.

The Sir Michael Stoute-trained favourite Assessment burst through the stalls and had to be withdrawn.

Ed Crisford said: “It’s nice to see him bounce back as we ran him in the Lincoln on terrible ground. We probably shouldn’t have done that, but he’s bounced back today in good style.

“He’s a lovely horse. They went quite hard up front and William sat just off the pace and I thought he rode a very nice race.

“He travelled into it so well. I thought they were coming after him, but he kept finding more.

“We can head to the Hunt Cup now – that’s the plan. It should be a good race for him as a strong pace and a big field should suit.”

The Crisfords doubled up when 3-1 favourite Chesspiece won the Collective Green Energy Handicap under Ryan Moore.

“He did it very well. It was just the third race of his life and we always felt he wanted a step up in trip,” said Ed Crisford.

“We were a little worried about the ground but he went on a fine and he’s got a big future. I’d say the Queen’s Vase would be the plan as an extra two furlongs would suit him well.”

Regional continued trainer Ed Bethell’s excellent run of form with victory in the Lindum York Handicap.

The Middleham-based trainer had enjoyed winners at Nottingham, Haydock and Leicester in the past seven days and Regional was a 5-1 shot to add to his tally on his seasonal reappearance.

Ridden by Callum Rodriguez, the five-year-old was in front racing inside the final furlong and had enough up his sleeve to repel the slow starting but fast finishing Korker by half a length.

Bethell said: “It wasn’t the plan to make the running, but he’s a decent horse and always has been ever since we’ve had him.

“He came third in the Stewards’ Cup and has been unlucky in other handicaps. I’m just delighted for the guys that own him and he’s a fun horse for the summer.

“He ran off 100 in the Stewards’ Cup, I think that’s his mark in handicaps and I would think he will go to 104 or 105 after today. That makes life difficult, but there is the City Walls back here (a Listed race in August) and he’s shown me he’s electric today, which is something I didn’t think he was.

“I thought he would miss the break and finish, but he’s not missed the break, he’s made the running and shown me that he’s quick enough and talented enough to do it.”

Rory McIlroy was unable to hide his frustration after making a slow start to the 105th US PGA Championship.

Following a delay of almost two hours due to overnight frost, Oak Hill member McIlroy failed to register a birdie as he covered his opening nine holes in three over par.

Starting from the 10th, McIlroy began his bid for a first major title since the 2014 US PGA with five straight pars before badly mishitting his tee shot on the par-three 15th to find a bunker 30 yards short of the pin.

McIlroy hit a good bunker shot to nine feet but was unable to convert the par putt and also failed to get up and down from sand on the 17th, before taking a swipe at the tee marker on the 18th following another errant drive.

A third bogey of the day dropped McIlroy six shots off the early lead shared by 2011 US PGA champion Keegan Bradley, Sahith Theegala and Japan’s Kazuki Higa, who had earlier carded four birdies in a row from the 11th.

Play had been scheduled to get under way at 7am local time (1200 BST), but predictions of cold conditions overnight were accurate.

Tournament organisers released a statement early on Thursday morning which read: “Due to frost, all Oak Hill Country Club practice facilities and the golf course are currently closed.

“To protect playing surfaces, everyone on-site must stay off any grass and gates will not open until the frost clears.”

With the temperature slowly rising, officials announced the first group would tee off at 0850 from the first and five minutes later from the 10th, a total delay of one hour and 50 minutes.

The possibility of weather delays had been on the cards since the US PGA was moved from August to May in 2019, with Oak Hill having already been selected as this year’s venue.

Speaking on Tuesday, the PGA of America’s chief championships officer Kerry Haigh said: “Wherever the championship is (in May) appears as though it will bring some more variety to the weather than we’re used to having when we played in August.

“There is the possibility of a frost again on Thursday morning. We had a frost Tuesday morning. We had a couple of frosts last week. That may delay the start. Hopefully it won’t. But if it does, we’ll adapt.

“We’ve got the chance of rain on Saturday and hopefully clear on Sunday. That’s sort of the fun of golf. It’s an outdoor game and we can’t wait to see what Mother Nature brings as well.”
