The first two athletes to test positive for coronavirus in Tokyo's Olympic Village have been confirmed as members of South Africa's men's football team.

Games organisers announced in their daily update on Sunday that there had been 10 positive cases in the latest round of testing, taking the overall total this month to 55.

That includes three individuals based in the athletes' village, with an event official previously testing positive on Saturday.

The South African Football Association released a statement later on Sunday confirming Thabiso Monyane and Kamohelo Mahlatsi were the pair to return positive tests.

Orlando Pirates right-back Monyane and Moroka Swallows attacking midfielder Mahlatsi, plus video analyst Mario Masha, will now isolate in a hotel room for 14 days.

A fourth South African participant, rugby sevens coach Neil Powell, also produced a positive result. All four individuals tested negative before flying to Japan this week.

Team South Africa chief medical officer Dr Phatho Zondi said in a statement: "Every member of Team South Africa required full medical clearance as an eligibility criteria. 

"In addition, they were encouraged to isolate for two weeks pre-departure, monitor health daily, report any symptoms, and produce two negative nasopharyngeal PCR tests taken within 96 hours of departure, as per Tokyo 2020 requirements.

"The timing of the positive results suggests that the PCR test in these individuals was done during the incubation period of the infection, which is how they could be negative in South Africa and then positive in Japan. 

"They are now in isolation where they will continue to be monitored and will not be allowed to train or have any physical contact with the rest of the squad."

South Africa are scheduled to face tournament hosts Japan in their opening Group A game next Thursday, before taking on France and Mexico on July 25 and July 28 respectively.

Sunday's news of two athletes testing positive for COVID-19 inside the athletes' village will raise further concerns over the Olympics going ahead as planned.

The 2020 Games, already delayed by a year due to the global health pandemic, officially begins on Friday and will be held mostly without spectators due to a state of emergency being declared in Tokyo.

Infection rates in the Japanese capital have topped 1,000 for four days running.

Around 11,000 athletes from 205 national Olympic committees are expected to stay at the village over the next three weeks.

International Olympic Committee president Thomas Bach reiterated on Saturday that the first positive case posed no risk to the Japanese population.

"We are well aware of the scepticism a number of people have here in Japan," he added at a news conference. "My appeal to the Japanese people is to welcome the athletes for their competitions."

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."

Casper Ruud won his third ATP Tour title on Sunday thanks to a straightforward win over Federico Coria in the Nordea Open final.

The Norwegian needed just under 90 minutes to see off Coria, who was competing in his maiden tour-level final, getting the job done to win 6-3 6-3.

Ruud's electric start set the tone for the contest, as he raced into a 4-0 lead thanks to successive breaks – although Coria broke back to make it 4-1, his opponent's wobble was only brief.

Coria ensured the match was a little tighter initially in the second set, but Ruud's class showed as he rattled off three breaks on the trot and eventually converted his fifth match point in front of a joyous support.

"It was an incredible week, maybe the best week of my life," Ruud said after sealing the title without losing a single set.

"It's an incredible feeling playing here in Bastad with the Swedish, Norwegian and Danish support. There is nothing like that home crowd feeling.

"To win here means a lot. You get a little extra nervous as the No. 1 seed. Me and my father [former player Christian Ruud] have been joking about when I am going to beat him at this and this, and now I think I have beaten him in everything!

"The Ruud family can finally bring the trophy home to Norway. It is a special feeling having him here with me."

Tamara Zidansek recovered from a set and early break down to beat Clara Burel and win her first WTA singles title at the Ladies Open Lausanne.

The Slovenian had lost her previous two finals, including at the Copa Colsanitas in April, but she lived up to her top-seed billing on Sunday by beating Burel 4-6 7-6 (7-5) 6-1.

Burel had eliminated second and fifth seeds Fiona Ferro and Caroline Garcia en route to her first final and made a fast start by breaking Zidansek twice in the first three games.

Former junior world number one Burel was in control at 4-0 up and saw the job through in the first set, despite Zidansek pulling it back to 5-4 at one point, with a backhand winner.

Zidansek was a break down in the second set when beginning her impressive comeback, which saw the French Open semi-finalist take four of the next five games.

But Burel continued to match her opponent as the second set went to a tie-break, with Zidansek recovering from 4-2 down to take it 7-5 and level up the contest.

World number 50 Zidansek took control from that point and eased to victory in the third set with three breaks, clinching her maiden title when Burel miscued a backhand.

Lewis Hamilton was accused of "dirty driving" by Red Bull boss Christian Horner after a first-lap collision put Max Verstappen out of the British Grand Prix.

A breathtaking start to the race culminated in title rivals Hamilton and Verstappen making contact at Copse Corner.

Verstappen was sent spinning off the track and into the barriers, with his car left in a crumpled heap.

The championship leader was able to walk away from the wreckage but was left "massively winded", according to team principal Horner.

It was the most sensational moment of the season, reflective of the intensity of the rivalry between reigning champion Hamilton and this year's leader in the standings.

Hamilton was looking to get ahead of his rival on the inside when wheels touched and Verstappen was sent spinning off the track, Horner denouncing what he considered "a desperate move".

Horner was furious with Hamilton, whose driving was scrutinised by the stewards as the race was red-flagged, with the cars returning to the pit lane while the barrier was repaired.

Verstappen was said to have come out largely unscathed, while Hamilton received a 10-second time penalty when the race eventually resumed.

"He's gone to the medical centre for a check-up. But that's a hell of a relief to see him get out because that corner's one of the fastest on the calendar," Horner told Channel 4.

"[It was] completely out of order [for Hamilton] to stick out a wheel on the inside there. It was way too far. Every driver that's driven this circuit knows you don't stick up the inside at Copse.

"He's done it and obviously his front left has made contact with Max's right rear, on one of the fastest corners in the championship and he's put him in the fence. Thank god he's not been hurt. As you can imagine, we're pretty annoyed about things.

"I think it was a desperate move. He failed to make the move in the first part of the lap which he was obviously geared to do.

"Then it was a desperate move sticking a wheel up the inside. Copse is one of the fastest corners in the world, you don't stick a wheel up the inside, that's just dirty driving.

"That's just not on and I'm just relieved to see our driver's walked away because that could have been a very, very nasty accident."

Pablo Carreno Busta beat Filip Krajinovic in the final of the Hamburg European Open to lift his first ATP 500 trophy.

Spanish second seed Carreno Busta wrapped up a convincing 6-2 6-4 win over Krajinovic of Serbia in one hour and 23 minutes.

Krajinovic, who beat Stefanos Tsitsipas in the quarter-finals, had no answer to Carreno Busta's serve as he won 81 per cent (21/26) of his first-service points.

Carreno Busta broke Krajinovic's serve twice in the first set before he served out. 

Krajinovic showed more fight in the second set, but he was unable to create a break chance, and when he offered one to Carreno Busta his opponent seized it.

The victory gave world number 13 Carreno Busta, who did not drop a set in the tournament, his 17th win on clay this season.

Facundo Pellistri got the decisive goal as Manchester United began their pre-season preparations with a 2-1 win over Wayne Rooney's Derby County.

United great Rooney took over from Phillip Cocu in November and was managing against his former club for the first time.

It was, understandably, an unfamiliar-looking United side, however. With numerous players yet to return after Euro 2020 and the Copa America, and several set to feature at the Olympics, Ole Gunnar Solskjaer was without 16 players.

As such, Tom Heaton started in goal following his return to the club, and he made an important save from point-blank range just before the end of a first half that was made to look like something of a struggle due to the heat.

Nevertheless, United held a 1-0 lead at the interval as Tahith Chong – who is set to go on loan to Derby's Championship rivals Birmingham City – seized on a defensive error and bundled in from close range after seeing his initial chip attempt blocked back on to him.

Solskjaer made as many as nine changes at the break, with Axel Tuanzebe and Teden Mengi the only players to remain in the team. Jesse Lingard, Andreas Pereira, Nemanja Matic, Lee Grant and Alex Telles were among those to come into the side, with several youngsters also involved.

Two of the young hopefuls combined to put United 2-0 up.

Shola Shoretire – who became United's youngest ever player in European competition back in February – sliced through the defence with a clever throughball and Pellistri coolly rounded the goalkeeper before tucking home.

Colin Kazim-Richards pulled one back for Derby from distance, but Pellistri's well-taken goal was enough to give United a winning start to their pre-season

Max Verstappen crashed out of the British Grand Prix on the first lap after a stunning collision with title rival Lewis Hamilton.

It had been a dazzling start to the race with the front-row pair going neck-and-neck in the opening corners.

They came close to making contact earlier on the lap before they finally did so at Copse Corner, Hamilton looking to overtake championship leader Verstappen on the inside but clipping the Red Bull driver's right rear wheel.

The tyre came flying off and Verstappen's car went crashing across the gravel and into the barriers at high speed.

Verstappen was able to walk away from the incident without any serious injury, but was said by team boss Christian Horner to be "massively winded".

Hamilton reported damage to his Mercedes car over the radio to his team, and told them: "I was ahead going in there, man. He turned in on me, man."

The result was that the race was red-flagged to allow for repairs to be carried out to the barriers, meaning it would have to re-start.

Barbora Krejcikova won the Prague Open on Sunday with a comfortable win in straight sets against Tereza Martincova.

World number 13 and tournament second seed Krejcikova eased to a 6-2 6-0 win over her Czech compatriot Martincova in one hour and five minutes.

The win was the French Open champion Krejcikova's first on hard courts and came courtesy of 26 winners across the 14 games.

At 2-2 in the first set Krejcikova secured a break against the world number 78 and from that point never looked back.

Krejcikova has now chalked up an impressive 20 wins from her last 21 matches.

The 25-year-old's solitary loss in that time was in the fourth round of Wimbledon at the hands of eventual champion, and world number one, Ashleigh Barty.

Ronald Koeman believes Spain should have given Barcelona teenager Pedri a rest rather than call him up for the Olympic Games.

The midfielder was a key part of the Spain squad that reached the semi-finals of Euro 2020, becoming the first ever player to start six games in a single European Championship or World Cup aged 18 or below.

Instead of being given time off before the start of Barcelona's LaLiga campaign, Pedri is in Japan for the Olympic football tournament.

Spain play their first game in Group C against Egypt on July 22 before fixtures with Argentina and Australia.

Koeman told a media conference: "Pedri has played a lot. We will have to give him a break, everyone needs it during the [European] summer. 

"As Pep Guardiola said, playing two important tournaments in the summer is too much, but we can't do anything. 

"Pedri's European Championship was phenomenal. At the age of 18 he has played almost all the complete matches, with an impressive maturity. 

"His football continues to improve and he is a very honest and calm boy. He lives for football. He is an example of how to be a young man at Barca.

"It is important for our grassroots football, that young people see that they are in a club that gives them opportunities."

Also in Spain's squad for the tournament is defender Eric Garcia, who re-joined Barca from Manchester City on a free transfer.

Koeman tipped the 20-year-old former Barca academy player to have a big impact on the first team when he is able to link up with the club following the Olympics.

"He has had a great European Championship," Koeman said. 

"He comes from here and, despite his youth, he already has a lot of experience. He plays in the same position I did. 

"With the ball he is very good and we can improve from behind with him. He also has projection and a great future ahead."

Meanwhile, Koeman hopes Ousmane Dembele can make a swift return from injury.

The France forward, whose contract at Camp Nou expires at the end of the 2021-22 season, is recovering from surgery on a knee injury sustained at Euro 2020 that is expected to keep him out for four months.

Dembele's career since his move to Barca from Borussia Dortmund for €105million four years ago has been blighted by injury setbacks.

The 24-year-old has managed just 54 LaLiga starts in four seasons at Camp Nou, while last season he completed 90 minutes in the league on just five occasions.

"I am very disappointed with his injury," Koeman added.

"Also, the situation with his contract is complicated. It is a pity for himself and for us. 

"He brought us a lot last year, different from what we have. I hope he can come back soon."

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.

Ronald Koeman has warned Barcelona's rivals a rejuvenated and focused Lionel Messi will have a massive impact in the forthcoming season.

Messi is technically still a free agent after his contract with the Blaugrana expired at midnight on June 30, but it has been widely reported the 34-year-old is poised to sign a new five-year deal at Camp Nou.

Messi was again hugely influential for Barcelona last season, finishing as LaLiga's top scorer and managing 38 goals and 12 assists across all competitions.

He also created 117 chances for others and netted a goal every 110.32 minutes over the course of 2020-21. 

The Argentina international is expected to take a substantial pay cut to stay at Barca but Koeman does not expect his influence to diminish.

"Messi is very important, he is the captain of the team and an example," head coach Koeman told a media conference on Sunday.

"After a difficult start due to his own situation, his effectiveness was enormous [in 2020-21].

"He really wanted to win the Copa America and, as he is the best player in the world, he is used to winning things. For me, he is the big favourite to win the Ballon d'Or."

Koeman claimed the presence of Messi and other experienced players will bring balance to Barca in the new campaign.

"The veteran players have a place in the squad," Koeman explained.

"They already showed it last year and it is important that they be with us. In a club like Barca, the balance between the oldest and the youngest must exist."

Koeman has taken some of the attacking burden of Messi shoulders with the signings of Memphis Depay and Sergio Aguero on free transfers.

Depay enjoyed a fine final season in Ligue 1, scoring 20 times, trailing only Paris Saint-Germain star Kylian Mbappe (27), while his 12 assists and 94 chances created were the most in France's top flight.

Aguero scored a club-record 260 goals in 389 appearances in all competitions during a glittering decade with Manchester City.

"I know Memphis very well and he knows how to work," Koeman added.

"He has a lot of character, physicality, speed, he can play in different positions in attack. He's the perfect age to show it.

"With Sergio, we had to improve our performance at the top and he is a very experienced and dangerous player in the penalty area. 

"The important thing is that he is physically well and our goal is to keep him in top form."

South Africa have confirmed Bongi Mbonambi, Scarra Ntubeni and Dan du Preez have been cleared to link up with the squad after completing their mandatory self-isolation period following positive COVID-19 tests results.

The trio were forced to sit out South Africa A's victory over the British and Irish Lions on Wednesday, as well as the shock 17-14 defeat to the Bulls at Cape Town Stadium.

With six days to go until the series opener against the Lions in Cape Town, all three players have been cleared to resume training with their team-mates.

South Africa had not played a Test match in 20 months prior to beating Georgia two weeks ago, and Kwagga Smith accepts there is a lot of work ahead for the reigning world champions.

"We haven't played Test matches in almost two years, so we got together and started working on it in the last three games and we can now analyse that," he told SA Rugby's official website.

"We need to use our opportunities because in Test matches there aren't many of them, so we have to convert them into points, and we have to sharpen up and get into our system and enforce it onto them."

The majority of the Boks' fringe players failed to impress in the defeat to Bulls, whereas the Lions flexed their muscles with a 49-3 win over the Stormers in their final warm-up match.

Cobus Reinach, one of the rare shining lights for South Africa on Saturday, agrees with Smith that a big improvement is needed if his side are to stop Warren Gatland's men.

"We left a lot of opportunities on the park, but that is something for us to look at, and each one of us has to look at our performance," he said.

"We can improve, and we have to ensure that we do better when we find ourselves in a similar situation. We are aligned as a squad and we know what we have to do.

"We need to execute what we want to do at a platinum standard, and everyone just needs to do their job and make sure they do it well.

"Collectively we didn’t put our stamp down, but we can fix that, and we are feeling confident going forward."
