Top seed Elise Mertens was knocked out as Daria Kasatkina won through to the Silicon Valley Classic final where she will meet Danielle Collins.

Fourth seed Kasatkina swept aside world number 17 Mertens in one hour and 21 minutes, winning 6-3 6-2 in San Jose.

The 24-year-old Russian progresses to her fourth final of the WTA season, claiming her third win from four meetings against the Belgian.

The win was former top 10 player Kasatkina's fourth triumph over a top 20 player this year.

Kasatkina broke Mertens three times throughout the match, never dropping her own serve, sending down 4-2 aces.

Mertens was not helped by seven double faults throughout the match, with Kasatkina saving the Belgian's only break point.

Kasatkina will face American seventh seed Danielle Collins who was too good for Ana Konjuh. Collins only needed 52 minutes to win 6-0 6-2 over the Croatian qualifier.

Konjuh struggled on serve throughout, with Collins breaking her six times, while she only won one from 17 points on her second serve.

American Mackenzie McDonald toppled former champion Kei Nishikori in three sets to claim a spot in the Citi Open final on Sunday against fifth seed Jannik Sinner.

McDonald triumphed over unseeded Japanese Nishikori 6-4 3-6 7-5 in two hours and 45 minutes in Washington DC.

The 26-year-old American's win qualifies him for his maiden ATP Tour final, sending down 4-1 aces while getting a slight edge with his return.

Nishikori, who triumphed in DC in 2015, fought back when trailing a set and a break in the second with four straight games to send it to a third.

The 31-year-old Japanese appeared to have the momentum but McDonald responded to outlast him.

McDonald will face 19-year-old Sinner who overcame another emerging talent, American 20-year-old Jenson Brooksby, 7-6 (7-2) 6-1.

Sinner becomes the first Italian to reach the final in DC and also progresses to his first ATP 500 decider.

The Italian continued his fine run in DC, having not yet dropped a set all tournament, marking a return to form after being on a four-match losing run.

Sinner saved three set points at 5-6 in the first to fight back to take the lead in a tiebreaker before a dominant second.

Eliud Kipchoge defended his Olympic marathon title in sensational fashion before telling those at home to "be inspired" and expressing his belief Tokyo 2020 has shown there is "hope" towards a return to normality.

The Kenyan legend became just the third person to successfully defend an Olympic marathon title and the first athlete to do so since 1980.

Kipchoge's time of 2:08:38 was 1.20 faster than Abdi Nageeye and was a sensational result considering the searing heat in Sapporo. It also marked the largest margin of victory since Frank Shorter's win in 1972.

Afterwards, Kipchoge – who now has four Olympic medals to his name – used his platform to deliver an inspirational message about how the Games have provided a sense of normality amid the ongoing coronavirus pandemic.

Speaking to BBC Sport, he said: "Firstly I want to say thank you to everyone for the support and to those that made the Olympics, Tokyo 2020 happen.

"I am happy to defend my title and to show the next generation, if you respect the sport and be disciplined you can accomplish your assignment.

"It was not easy, but it was really hard for everybody if you consider the weather. I am happy to cross the finishing line as the fastest.

"Tokyo 2020 has happened, it means a lot, it means there is hope. It means we are on the right track to a normal life. So we are on the track to our normal lives that is the meaning of the Olympics.

"Thank you to all fans, to all the people in the whole world who were watching, be inspired."

The men's marathon was the last athletics event of Tokyo 2020 ahead of Sunday's closing ceremony, which is due to start at 8pm local time.

Paris Saint-Germain head coach Mauricio Pochettino insisted his players were not distracted by Lionel Messi rumours ahead of Saturday's hard-fought 2-1 win over Troyes.

PSG commenced their Ligue 1 campaign with the come-from-behind victory after goals from new signing Achraf Hakimi and Mauro Icardi.

The Parisians have been heavily linked with Lionel Messi in recent days after Barcelona confirmed his departure but Pochettino insisted that had no impact on his team's display.

"No, I don't think so, the players and the team have been focused," Pochettino said at the post-game news conference. "They are professionals.

"His name is associated with different clubs, there are plenty of rumours, but the players have remained committed, they will be until the end of the transfer window.

"We will see what happens in the next few days."

Pochettino admitted it was a "difficult" game for PSG, who are aiming to re-claim the Ligue 1 title after missing out to Lille last season.

“It was a very difficult meeting, we did not start well," the Argentine said. "We conceded an early goal, we have to do a lot better. We conceded too many chances for my liking.

"There were good and not-so-good periods in the game but overall I'm happy. It was very important to get the three points and start the season in this way.

"We have to give credit to Troyes who made the game difficult for us. I hoped for better, but the opponent showed energy.

"We are still at the beginning of the season, still in the process of breaking in. We still hope to win 5-0, but we take this victory as it is."

PSG return to action on Saturday against Strasbourg.

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

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

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

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

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

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

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

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

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

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

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

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

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

Warren Gatland says the British and Irish Lions gave it everything but came up just short in their agonising Test series defeat to South Africa.

The Lions suffered last-minute heartbreak in Cape Town as Morne Steyn's penalty secured a 19-16 win for the Springboks, who take the series by a 2-1 scoreline having lost the opening match.

Gatland's side had taken early control of the decider, Ken Owens' try helping them claim a 10-3 lead before half-time.

However, the Lions were made to rue missed opportunities as the reigning world champions fought back, with veteran fly-half Steyn coming off the bench to land the knockout blow – just as he had done in the 2009 series between the same teams.

Nevertheless, Gatland was unable to fault the efforts of his players.

"I'm disappointed, but really proud of the guys," Gatland told Sky Sports. "We spoke beforehand about winning these Test matches being about big moments.

"We had a two-on-one when maybe Josh Adams should have scored and a couple of times we were held up across the line. 

"I thought we were bold in terms of the tactics and what we wanted to do and tried to play rugby.

"We had a couple of calls which didn't go our way and bounces of the ball, particularly the try they scored, but I'm really proud of the effort. 

"I can't ask the guys more than the guys giving 100 per cent and they definitely did that."

Brendan Rodgers has announced Wesley Fofana will not play again until 2022 after sustaining a medial ligament injury in a pre-season friendly against Villarreal.

Fofana was carried off on a stretcher on Wednesday after a tackle from Fer Nino injured his left leg, with the centre-back later revealing on Instagram he had fractured his fibula.

The France Under-21 international is expected to undergo surgery on Monday, though the extent of the damage is worse than initially feared.

Following Leicester City's 1-0 Community Shield triumph against Manchester City at Wembley Stadium, Rodgers provided a further update on Fofana.

"He has his operation on Monday and he won't play until 2022," the Leicester boss said in his post-match news conference. "At what point that will be we'll have to assess over the next six months or so.

"He's an incredible talent. He's in really good spirits. He'll be back in the training ground on Thursday or Friday next week and will begin his rehab then.”

Fofana became an integral part of Rodgers' team following his arrival from Saint-Etienne.

Out of all Premier League defenders, Fofana was just one of two to attempt at least 50 tackles, complete 50 interceptions and produce 50 headed clearances – Aston Villa's Matt Targett being the other.

"It's such a shame for the Premier League not to have a talent like that and certainly for us as well," Rodgers continued after Kelechi Iheanacho's late penalty had defeated the reigning Premier League champions.

Asked for clarification as to whether the defender had broken his leg, Rodgers responded: "In and around his medial ligament there was a lot more damage than we had hoped, quite substantial damage unfortunately."

While Leicester will be without Fofana for the remainder of the year, they will be buoyed on by the return of Harvey Barnes.

Barnes, who scored nine goals and provided four assists in 25 top-flight fixtures last term, suffered a setback in April with a knee injury ruling him out of the remainder of the season and subsequently contention for England's Euro 2020 squad.

"Unfortunately, I had to watch the amazing scenes [in the FA Cup final]," the 23-year-old told ITV after Saturday's win. "This time, to be on the pitch and be a part of it was amazing.

"I don’t think we approached it as a friendly. It’s a chance to win some more silverware – and something we’ve not won before. We knew it was a great opportunity to win something before the season started, so we’re over the moon with it.

"It’s obviously been a tough few months for me. It’s amazing to be back out there now. This is the first competitive game I’ve played in and for the fans to be back in at Wembley was special. I’m feeling really good and looking forward to the season now."

Paris Saint-Germain kicked off their Ligue 1 campaign with a 2-1 victory despite suffering an early scare against Troyes.

Oualid El Hajjam's ninth-minute header had the hosts on top but their delight was cut short 10 minutes later when Achraf Hakimi smashed in a first goal for his new club.

Mauro Icardi doubled the blow two minutes later with what proved to be the winner, poking past goalkeeper Gauthier Gallon after good work by Kylian Mbappe.

Amid speculation over the possible arrival of Lionel Messi in Paris, Mauricio Pochettino's side started positively on the field as they look to recapture a Ligue 1 crown which they have claimed in seven of the past nine seasons.

Thilo Kehrer's last-ditch intervention made amends for centre-back partner Presnel Kimpembe's early mistake as Troyes threatened, though PSG did not escape so lightly from the resulting corner. El Hajjam greeted Dylan Chambost's inswinging delivery as the centre-back nodded past Keylor Navas.

Ander Herrera sent a rising effort into the side netting but shortly after Hakimi restored parity, powering onto Herrera's pass before blasting a right-footed volley into the roof of the net.

Things rapidly worsened for the hosts when Icardi added a second, the forward prodding home after Mbappe's cutback found his team-mate inside the area.

Mbappe thought he had scored himself when he rounded Gallon and curled towards goal, only to be denied by Jimmy Giraudon's goal-line clearance.

Renaud Ripart induced a smart reflex save from Navas to keep out a drilled strike that seemed destined for the net, while Mama Balde's audacious acrobatics had the PSG goalkeeper scrambling after the break.

Back-to-back opportunities followed for the away side to finish the game off but neither went in, Icardi flicking a header wide and Mbappe bending a shot narrowly over the crossbar.

What does this mean? PSG off on the right track

A good start to make amends for last season's underwhelming campaign was vital for Pochettino and they began in positive fashion despite an initial blip.

While PSG had lost just one of their previous nine opening games in Ligue 1 (W5 D3), they were beaten by Lens to open the 2020-21 season. However, Saturday's win sets the visitors off in the right direction to reclaim their crown.

Hakimi's happy debut

Hakimi's equaliser rapidly removed any nerves for the away side, smashing in to become the first player since Metehan Guclu in 2019 to score on his top-flight debut for PSG.

Since the start of the 2019-20 campaign, only Robin Gosens (34) has more goal involvements for a defender across Europe's top five leagues than Hakimi (31), while his goal here saw him become just the second Moroccan to score in Ligue 1 for the club.

Tough outing for Touzghar

Yoann Touzghar almost profited from Kimpembe's early error to square across Navas' goal, though his performance declined from there on in.

The forward cut an isolated figure up top, winning just 33.3 per cent of his duels as he touched the ball just 20 times – the lowest figure for any player who started the game.

What's next?

PSG host Strasbourg next Saturday - could Messi be part of the squad by then? As for Troyes, they travel to Clermont Foot the day after.

Jack Grealish's Wembley cameo impressed Pep Guardiola and the Manchester City manager is in bullish mood for the new season despite a 1-0 Community Shield defeat to Leicester City.

British record signing Grealish appeared as a second-half substitute in the traditional English curtain raiser, but Kelechi Iheanacho came off the bench to win and convert a late penalty against his former club.

Back at the stadium where he was the focus of adoration during England's Euro 2020 campaign, £100million man Grealish was rapturously received by the Manchester contingent, but the Leicester fans jeered his every involvement.

That amounted to a tidy 15 of 16 passes completed, including one chance created for fellow substitute Ben Knight, with 25 touches overall and seven duels contested in 25 minutes on the field.

"I saw many incredibly good things today. I don’t feel we played badly. I said to all the guys how proud I am," Guardiola told a post-match news conference.

"But in this business, you must win. And when you don't, congratulate the opponent.

"Jack was really good – aggressive, going against full-backs. Every time he had the ball he had three players [drawn towards him].

"We will find the tempo, he will know his mates, we will know him and, step by step, we will find our best.

"I know he is a lovely guy so he will adapt quickly.

"He didn't come to play 25 minutes, he came to play five or six years, that's why we will be incredibly patient like we will be for all new players every time they come."

Guardiola reserved praise for teenagers Cole Palmer and Sam Edozie, who were rewarded with starts after impressive pre-season showings in the absence of a host of international stars including Kevin De Bruyne, Raheem Sterling, Phil Foden and Gabriel Jesus.

Winger Edozie scored three goals in three friendlies, only to shank a clear first-half opening against Leicester. However, Guardiola felt the 18-year-old's response spoke volumes.

"What I like from them is they lost one or two balls and then the next one, try again and try again," he said.

"Cole was exceptional all game. In the first half [Ricardo] Pereira won the duels with Sam but second half he was incredibly aggressive.

"Since minute one in the second half, Sam took the ball and was aggressive

"Unfortunately, we missed some chances and did not create much up front, but the game was there."

Guardiola again bemoaned a schedule that has denied him much time on the training ground with key stars, but he is confident City can deliver as they pursue a fourth Premier League in five seasons.

"Mentally, yeah, of course I'm ready. But how can we be ready when some of the players have three or four training sessions?" he added.

"We have to adapt, adapt and adapt. We did last season when we started a little bit flat. After a while we were there and started to win.

"After what I saw today, I am incredibly confident that many good things are going to happen this season."

South Africa captain Siya Kolisi hailed team-mate Morne Steyn after his late penalty sealed a series victory for the Springboks over the British and Irish Lions.

Steyn came off the bench and proved the difference in Cape Town – his last-gasp kick securing a 19-16 win.

It was a first Test appearance in five years for the 37-year-old fly-half, who also landed the crucial blow in the 2009 series against the Lions.

The Lions were unbeaten in the final Test in each of their last three tours, but in a tightly contested tussle the Springboks produced a turnaround from 10-3 down to snatch a dramatic victory.

"As soon as he went for the kick, I thought 'no way!' It was beautiful to see him stay strong," Kolisi told Sky Sports.

"We didn't think he would come back and play. In his wildest dreams, he didn't think he'd get this opportunity again, so I'm very happy for him and the team.

"It was really challenging for both teams because there was a lot happening. But we focused as much as we could on what we had to do on the field, and that was most important.

"This is huge, 12 years – I will never get this opportunity again. I'm really honoured and proud of the team that we were able to achieve this. We can't compare it to anything else."

It was a heart-breaking end for the Lions and Alun Wyn Jones, who joined Mike Gibson and Graham Price as the fourth most-capped player in their history with 12.

Nevertheless, the skipper – who initially seemed set to miss the tour due to injury – revealed his sense of pride in the efforts of Warren Gatland's side.

"We are hugely disappointed – we were in it until the death. We had an opportunity at the end," he said.

"I am very proud of the boys and very conscious of who we represent but as I said, hugely disappointed at the same time.

"We wanted to come out for the second half with more of the same, we did that probably after the early exchanges, then the to-ing and fro-ing with the penalties broke up the game.

"It was probably similar to what we have seen in patches in previous games, we wanted to kick on but we could not do that."

Dani Alves says winning Olympic gold is his greatest achievement in football after Brazil overcame Spain to reign at the Games once again.

Brazil secured back-to-back golds on Saturday, following on from their Rio 2016 triumph with a 2-1 victory after extra time.

Mikel Oyarzabal levelled to bring Spain back into the game after Matheus Cunha's opener but Malcolm came off the bench to capture Olympic glory.

Alves, a three-time Champions League winner who also has six LaLiga titles on his resume, proclaimed Tokyo to be his greatest success in football.

"To be sincere, yes," the 38-year-old responded when asked if this was his greatest prize. "Because the others are every year, and I have competed time and time again, but with this medal, this is my last chance. I won’t make it to Paris.

"This means a lot for me. Everybody trusted in me, and I knew this would be a once-only opportunity, to be able to enjoy this dream. It’s not every day that you become an Olympic athlete, and even less at the age of 38.

"And so I came here like everybody else, as a virgin, to this competition. I came with the boys to live the dream with them. And we have managed it, after a lot of effort and sacrifice, and we are taking the biggest prize back home, back to our people."

Captain Alves and his team-mates were reduced to tears at the full-time whistle as Brazil came out on top in a record-breaking fifth final appearance.

The last trophy missing from his illustrious collection of honours is the World Cup, so could he keep on going for his country?

"I’m a dreamer, a small dreamer, and more than a dreamer, somebody who executes their dreams," he said in response to questions about Qatar 2022.

"The most important thing is to fight, and that’s what I know what to do. I have the drive of a 23-year-old.

"I still want to do big things in football, and have respect for the profession, because when you have respect for your profession, it brings you great things, and which is what I'm living."

Morne Steyn was the hero for South Africa as, just like in 2009, his penalty proved decisive in a 19-16 series-clinching win over the British and Irish Lions.

Steyn had last made a Test appearance for the Springboks back in 2016 but the 37-year-old came on from the bench to prove the difference in Cape Town.

Having replaced Handre Pollard, whose kicking was off in the second half, Steyn converted two penalties to secure a hard-fought victory from a tense tussle.

After Steyn's first effort, Finn Russell's penalty seemed to have sent the series to a draw, only for Steyn’s boot to once again prove the Lions' downfall with a 79th-minute three-pointer.

The Lions seemed to have been handed an early blow when Dan Biggar was forced off injured after attempting to tackle Lukhanyo Am, wth Pollard converting South Africa's resulting penalty.

However, Biggar's replacement Russell kicked a penalty five minutes after his introduction to restore parity as he asserted himself on proceedings.

Russell was kicking again soon after, this time adding the extras after Ken Owens marked his maiden Lions Test start by bundling over at the back of the maul for the first try.

A second Pollard penalty reduced the deficit, while Russell had a fortunate escape when he made direct contact with Cheslin Kolbe's head, a slip from the South Africa winger helping the Lions remain at full strength.

Pollard's penalty dropped just short, yet the Springboks finally found the breakthrough moments later, Kolbe holding off Luke Cowan-Dickie's challenge to race over in the corner after a loose ball had broken in South Africa's favour – the try standing after a long TMO review for a possible knock-on from Jasper Wiese.

An Ali Price error handed South Africa a chance to extend their lead, though the Lions held firm and Russell kept his cool at the other end to arrow a three-pointer through the posts after Eben Etzebeth's mistake.

Steyn, South Africa's hero in the 2009 series, entered the fray with 16 minutes remaining, and his first act was to nose the hosts back ahead.

Am's foul on Conor Murray handed Russell the chance to level the scores, an opportunity which the Scot took coolly, but it was Steyn who had the final say.

Herschel Jantjies tried to run the ball after the Boks were awarded a penalty 40 metres out, though fortunately the referee called it back, with Steyn holding his nerve to down the Lions.

OLD NEMESIS STEYN BACK TO HAUNT THE LIONS

Steyn kicked the penalty which settled the 2009 Lions tour in South Africa's favour, and history repeated itself on Saturday.

His 67th Test cap will last long in the memory for South Africa – two penalty opportunities, two successful attempts and a series win. He made four kicks in total in his 18 minutes on the field, including the final one out of play to signal full time and the end of the series. 

South Africa's triumph also means all three matches in this year's Test series were won by the side trailing at half-time.

RUSSELL'S EFFORTS NOT ENOUGH

Like his fellow substitute Steyn, Russell ended the match with a perfect record from the boot – all three of his penalties and his conversion finding the target as he collected 11 points.

It was all in vain, however, and Warren Gatland will be left to lament the indiscipline his team showed in the second half after getting themselves into a strong position. Six Lions tours have gone to a deciding game since they became three-Test series in 1989, with the tourists losing on three occasions, winning twice and drawing once.
