Andrey Rublev finally got the better of compatriot Daniil Medvedev after a flashpoint involving a courtside camera in the Western and Southern Open semi-finals.

Rublev will now face Alexander Zverev in the decider, having ended Medvedev's bid for a Toronto-Cincinnati double.

Medvedev had never even dropped a set to his fellow Russian in four prior ATP Tour meetings and appeared to be on course for another dominant victory when he took the first set.

But the world number two clattered into a camera early in the second and all momentum was soon lost.

Medvedev complained about the positioning of the camera, claiming it had caused a hand injury and aiming a kick at the lens.

He swiftly called for treatment as his performance started to fall well below his lofty standards, with Rublev finally able to win a set after breaking in an epic 15-minute game.

A series of unforced Medvedev errors allowed Rublev to break again in the decider and seal a stunning 2-6 6-3 6-3 triumph.

Third seed Zverev fought back from a double break down in the final set to progress to the final with a 6-4 3-6 7-6 (7-4) win over second seed Stefanos Tsitsipas.

The epic match lasted two hours and 41 minutes, with Zverev responding strongly after appearing unwell to book his spot in the final against Rublev.

Rublev gets his Daniil degree

Asked to reflect on finally toppling Medvedev, Rublev told Amazon: "It's always tough to play against Daniil and to beat him.

"I think it gives me a bit more confidence that I can play against him, I can compete against him. There are still so many things to improve, but it's like I've passed university."

The victory came as a relief, with Rublev believing he was unfortunate even to be trailing in the first set.

"Inside I was thinking, when I was 6-2, the score shouldn't be like this," he said.

"The points were really tight, some little outs, little mistakes, some good shots from Daniil. The score was not real [in] the first set.

"Even the third set, I won 6-3 but the match was so intense. You saw so many rallies, so many long rallies, and it was so tough.

"It was a super mental match, a super physical match, exactly like a chess match."

Zverev's Novak mentality

Tokyo 2020 gold medalist Zverev had trailed 4-1 in the third set against Tsitsipas, but fought back with two breaks before winning in a tie-break.

"After I did the first break back I thought 'OK I have the chances'," Zverev said during his on-court interview. "I felt like he was not serving bombs. I felt like I was always in the rallies but I was losing the rallies because I was a bit low energy, so I started being a bit more aggressive, a bit of the Novak mentality that I had against him at the Olympics as well."

Zverev has a 4-0 record against final opponent Rublev but he was wary of his opponent.

"Favourite or not, I think if you're in the final, there's no easy opponent," he said. "Today he played incredible beating Medvedev."

Ronald Koeman had no complaints as Barcelona could only draw at Athletic Bilbao, hailing his battling side and Memphis Depay in particular.

Depay scored his first Blaugrana goal 15 minutes from time at San Mames to cancel out Inigo Martinez's opener and secure a point.

The Netherlands international became the first Barca player to have a goal involvement in each of his opening two LaLiga appearances (one goal, one assist) since both Cesc Fabregas and Alexis Sanchez in 2011-12.

Yet Depay could have added to his tally as he squandered the best of his three chances – valued at 0.24 expected goals – four minutes from time.

"I could have scored two goals," he told Barca TV. "In the end, I did it with the left.

"I am very pleased to have scored, for having scored my first goal, but disappointed not to have scored the second chance I had."

Koeman was pleased with Depay, however, adding: "He has scored a great goal and had a chance for another. We must highlight the attitude of the team after the 1-0 against.

"[Depay] has effectiveness, speed, strength. He's a great player, that's why we've signed him. You have to have personality, here the demand is better and he takes it well."

Indeed, despite Depay's late chance, Koeman suggested Barca would have been fortunate to win.

They had 67.3 per cent of the possession but just nine attempts to Athletic's 16.

"We initially lacked calm and the ability to find the free man," Koeman said. "We made mistakes and couldn't get out.

"Little by little we entered the game, we reacted well after the 1-0 and in the end we were better. We could even win, but maybe it would have been too much."

Barca had some issues at the back, with Eric Garcia sent off late on after Gerard Pique had departed with injury.

In a worrying trend, this is the sixth time in Pique's past 13 LaLiga starts he has failed to see out the full match, as many substitutions as in his previous 111 outings.

But Koeman said Pique's problem was "not serious and I hope he will be available for next week".

World number one Ash Barty reached yet another final on Saturday at the Western and Southern Open, where she will face wildcard Jil Teichmann.

Barty is through to her sixth title match of the season – and first in Cincinnati – after beating Angelique Kerber in straight sets.

In action on the WTA Tour for the first time since winning at Wimbledon, having gone to the Tokyo Olympics in the intervening period, the Australian came through a sloppy spell in the second set to advance 6-2 7-5.

Teichmann is next, taking on Barty for the first time after a stunning run continued with victory over Karolina Pliskova.

The world number 76 had already eliminated Naomi Osaka and Belinda Bencic and was a deserving 6-2 6-4 winner against Pliskova.

Barty finds the balance

Barty had been racing towards victory when she took the opener on Kerber's serve, her second break, and then went 2-0 up in the second.

But Kerber gave the favourite a scare by winning each of the next three games, belatedly finding joy against the Barty serve.

The All England Club champion has won more matches than any other player on tour this year, though, and regained her composure to break twice more for a 39th triumph of 2021.

"It's never, ever a walk in the park against Angie," Barty said. "She's an exceptional competitor and I think early on in that second set she went to another gear and it took me a few games to go with her.

"That was the change – she was able to lift her game and, even though there were some close games, she won the big points early on in the second set.

"I'm glad that I was able to find a way through there in the end.

"I had to find the balance of being aggressive and not getting too passive and letting Angie dictate.

"She moves exceptionally well, puts the balls in difficult positions, and I felt like when I was able to control the court I did a better job.

"In the games I got broken, she just saw too many second serves and was able to be assertive.

"I'm really happy to get through in the end, and to be playing for a title here in Cincinnati is awesome."

'Random' run wears on

Despite facing three seeds in succession, Teichmann has not dropped a set since losing the first against Osaka in the last 16.

Continuing that sequence against Barty will be a tough ask, but few would have anticipated Pliskova being brushed aside quite so easily.

Teichmann herself has no explanation for a sensational run of form.

"It's tough to explain," she said. "When I ask my coaches what they think of me, they always say, 'You're just an unexpected person, you do random things', so I guess that's one of them.

"I'm feeling really, really good here, the conditions, serving good, moving well, when I can I attack, I defend... What I'm feeling here, I cannot even describe it.

"It's a dream. I'm playing centre court, a final against the world number one. I cannot ask for anything else."

Memphis Depay's first goal for Barcelona secured a 1-1 draw for Ronald Koeman's side against Athletic Bilbao at San Mames on Saturday.

Barca started life without Lionel Messi – who joined Paris Saint-Germain earlier this month – with a 4-2 win over Real Sociedad last weekend, but they were well off the pace for much of the clash with Marcelino's side.

The hosts had seven shots to Barca's three in a lively first half and they deservedly went ahead five minutes after the restart when Inigo Martinez steered a header past Neto.

Former Lyon forward Depay ensured a share of the spoils 15 minutes from full-time, though, lashing home from an acute angle moments after Frenkie De Jong had hit the crossbar.

Eric Garcia was then sent off in the final moments of the match as Barca dropped their first points of the new season.

Martin Braithwaite squandered a glorious opportunity to put Barca ahead after six minutes, the Denmark international inexplicably blazing over from 10 yards after Depay's cross was deflected into his path.

That miss should have been punished five minutes later, but Oihan Sancet's instinctive effort crashed back off Neto's crossbar.

Inaki Williams headed over from inside the six-yard box shortly after the half-hour mark, while Ronald Araujo – who had earlier replaced the injured Gerard Pique – saw an overhead kick ruled out for a foul by Braithwaite in the build-up.

Araujo was in the thick of the action at the start of the second period, acrobatically clearing Alex Berenguer's strike off the line, but he was powerless to stop Martinez storming in to head home Iker Muniain's corner in the 50th minute. 

Neto pawed away Sancet's powerful strike soon after as Athletic continued to press, before Frenkie De Jong crashed a sumptuous half-volley against the crossbar.

His Netherlands team-mate was not to be denied, though, Depay thundering an effort past Julen Agirrezabala from a tight angle to secure a point for Koeman’s below-par side, who had Garcia dismissed deep into stoppage time for bringing down Nico Williams as he bore down on goal.

Mikel Arteta reckons Arsenal must be "perfect" to beat Chelsea on Sunday as he looks to get the north London club back among the Premier League challengers.

The Gunners started the new top-flight campaign in lacklustre fashion, going down to promoted Brentford 2-0 in the opening game.

A derby with Thomas Tuchel's side is next up and, after defeating Chelsea 3-1 in the same fixture last term, Arteta knows what it will take to be successful again at Emirates Stadium.

"What we have to do is perform, perform at the highest level," he replied when asked in a pre-match media conference if a draw would be a positive result.

"We know that to beat Chelsea we need to be perfect.

"Individually and collectively, we have to have an extraordinary game. The focus is going to be that."

Arsenal also triumphed 1-0 at Stamford Bridge towards the end of the previous season, too. They have not won three in a row against Chelsea in the league since a successful run between January 2003 and February 2004.

While Chelsea could be buoyed on by their record signing Romelu Lukaku making his return, Arteta has added Martin Odegaard and Aaron Ramsdale to his squad.

Asked whether spending money came with added pressure, Arteta made clear it is all part of the long-term planning at the club to get them back contending again.

"We are a football club that tries to make the right decisions and move forward," the Spaniard said.

"It’s never been down to me. When we have success, titles, or when we have difficulties, it's down to us with me here, and it will be like this in the future.

"What we want to do is bring this club back to where it was. We are going to do that, the timing of it is a little more complicated than people think, but the aim is to do that.

"The only aim going into all matches is to win, nothing else. Achieving that as quickly as possible is the only objective we have."

Inter boss Simone Inzaghi believes Hakan Calhanoglu "doesn't realise how good he is" after a stunning debut performance against Genoa on Saturday.

After joining from city rivals Milan in the close season, Calhanoglu marked his first appearance for the Nerazzurri with a superb goal and an assist for Milan Skriniar in his side's 4-0 win.  

Those two goal involvements came inside the first 14 minutes – it took him nine games to achieve that at the start of his Milan career.

Arturo Vidal added a third in the second half before former Roma man Edin Dzeko marked his Inter bow with a header in the 87th minute.

Champions Inter have now scored three or more goals in four successive Serie A home matches for the first time since 2011, when did they did it in six games.

Inzaghi was not surprised by his side's dominant display, and the former Lazio boss was particularly pleased with Calhanoglu's contribution.

"I was pretty confident the team would do well, as I've seen them working with enthusiasm and hunger since July 8, eager to learn new concepts," he told DAZN.

"We couldn't have asked for a better start, especially in front of our fans back in the stadium.

"Calhanoglu is a great player, able to unite quality and quantity. He ran so hard for the team as well. Every time I played against him, he caused me problems.

"We were fortunate enough to pick him up and I think he can get stronger, because he doesn't realise how good he is."

Inter lost last season's top scorer Romelu Lukaku to Premier League side Chelsea this month and Inzaghi confirmed that the club intend to dip into the transfer market to replace him, despite the arrival of Dzeko.

"Naturally we need to complete the squad, as Romelu Lukaku's departure was unexpected," he added.

"Dzeko has already shown what kind of player he is. Hopefully we'll bring in someone else who can score big goals."

Saturday's win at San Siro means Inter have won each of their last seven Serie A meetings with Genoa by an aggregate score of 25-0, while they are the first side to have scored four or more goals in their first game of the season in three successive campaigns since they did so between 1959 and 1961.

Inter expect Lautaro Martinez to stay at San Siro after he turned down "lucrative offers" from rival clubs, according to club CEO Beppe Marotta.

The Nerazzurri began their Serie A title defence on Saturday with a 4-0 win over Genoa, but there were significant changes to the side that won the Scudetto last season.

New signings Hakan Calhanoglu and Edin Dzeko were among the scorers, with Simone Inzaghi in the dugout for the first time.

Antonio Conte, Romelu Lukaku and Achraf Hakimi all left Inter, and Martinez was also linked with a move away, Tottenham considered potential suitors.

However, the Argentina international – absent against Genoa, having won the Copa America in the off-season – appears certain to remain at Inter.

Marotta, speaking before Saturday's game, revealed Martinez had options elsewhere but preferred to continue with the champions.

"Lautaro is a player who explicitly asked to stay at Inter, despite receiving other lucrative offers," Marotta told DAZN.

"We are proud of that. He wants to prove himself a champion here, and we are very happy that he can continue his growth process at this club."

Martinez scored 17 Serie A goals last season as well as supplying six assists, with a goal involvement every 112 minutes.

That was his most prolific campaign in Serie A, with 20 goals across the 2018-19 and 2019-20 seasons combined.

The forward will now link up with Dzeko, who marked his Inter bow and 200th Serie A outing with both a goal and an assist.

He and Calhanoglu, who also scored one and made one, became the first Nerazzurri debutants to achieve that feat since Zlatan Ibrahimovic in 2006.

Hakan Calhanoglu hit a stunning goal on his Inter debut and Edin Dzeko followed suit as new coach Simone Inzaghi was treated by his team to a 4-0 win over Genoa.

After defecting from Milan to join the Rossoneri's city rivals in the close season, Calhanoglu also managed an assist at San Siro, setting up the opener for Milan Skriniar.

This was about as ideal an opening-day outcome as former Lazio boss Inzaghi could have imagined, with his team two goals to the good inside quarter of an hour, making light of the changes that have followed their Scudetto success last season. Arturo Vidal got the third in the second half before Dzeko marked his Inter bow with a classic header in the 87th minute.

Inzaghi's predecessor Antonio Conte quit in May, Romelu Lukaku and Achraf Hakimi have departed in big-money deals, and as recently as Friday evening the influential technical chief Gabriele Oriali was "relieved" of his duties, but this did not look like a team in crisis.

Veteran striker Dzeko has arrived from Roma, and both he and Calhanoglu starred here, clicking immediately.

Stefano Sensi slotted in just behind targetman Dzeko in a 3-5-1-1 formation, but it was a defender who made the sixth-minute breakthrough. Calhanoglu notched nine assists for Milan in Serie A last season, and his first for the Nerazzurri arrived when his whipped corner from the right was headed powerfully into the left corner of the Genoa goal by Skriniar.

Genoa's marking left a lot to be desired, but there was little they could do to prevent Inter stretching their lead in the 14th minute with a delicious goal from Calhanoglu, who collected a short pass from Dzeko and thrashed a 25-yard shot into the bottom right corner.

Dzeko hit the crossbar with a deflected shot on the turn from Matteo Darmian's cross, and Ivan Perisic was denied a goal by a VAR offside verdict after sprinting through and beating Salvatore Sirigu, who had earlier saved well from Marcelo Brozovic.

Perisic was again marginally offside before he teed up Calhanoglu to rifle into the top left corner after the interval, and that meant another Inter goal did not stand.

They found a third goal in the 74th minute though, substitute Vidal drilling in from close range after Dzeko's shot was parried out. Nicolo Barella teased the ball into Vidal and he converted, with Dzeko later meeting Vidal's delicious delivery and making no mistake. Just like Inter all afternoon.

What does it mean?

This was about as smooth a start as the new regime could have hoped for, the early goals putting paid to any tension after the close-season upheaval. Beating a distinctly limited Genoa side can only tell us so much, with the real tests still to come, but Inter looked slick and the new recruits acquitted themselves admirably.

Dream start for Calhanoglu

The only disappointment for Inter's new playmaker came when his celebrations were short-lived the second time he found the net, due to Perisic straying offside. He came off after 76 outstanding minutes, receiving a big hug from Inzaghi. By half-time, Calhanoglu had chalked up a goal and an assist, among three chances created, an instant Inter hero. He created two further chances before being awarded a rest, and a deserved ovation.

Kallon catches the eye

Sierra Leonean striker Yayah Kallon looks a real prospect for Genoa, and on just his second Serie A appearance he gave Inter's defence cause for concern. Kallon should have buried a chance just before half-time but swept his left-footed shot wide of the right post. He drew a solid save from Samir Handanovic at the start of the second half before being substituted soon after. His talent is raw and he played just six passes in 54 minutes, while having only 20 touches, but the 20-year-old is one to watch.

What's next?

Inter will be back in Serie A action on Friday, when they travel to face Hellas Verona. Genoa have to wait an additional two days for their next game, a home encounter with Napoli.

A superb third-round 65 saw Anna Nordqvist storm joint top of the leaderboard heading into the final round of the Women's Open.

The Swede shot the best score of the week on Saturday thanks to seven birdies, including at three of the last five holes, to move to nine under par for the championship alongside Norway's Nanna Koerstz Madsen.

Nordqvist, seeking her third major triumph, is even beginning to enjoy the inclement weather at Carnoustie as rain made for a sodden third round.

"I felt like I hit the ball really, really well last week in the hard wind at Dumbarnie in The Scottish Open," she said. "So, it's started to feel like it's come together.

"I feel like the last few weeks have been solid. I just haven't made as many putts or scored as well as I played.

"My caddie just told me to keep patient. In links golf you test your patience and I feel like I've had a great attitude this week.

"I love Carnoustie. I think it's a great venue and I'm just enjoying being back in Scotland."

Madsen is also at nine under after a third round of 68, with Lizette Salas a stroke further back.

There are four women at seven under par including Scottish amateur Louise Duncan, who carded a fine 68 to the delight of the home crowd.

World number one Nelly Korda and Georgia Hall, who held a share of the overnight lead, are at six under par.

Mina Harigae, who was level with Hall after Friday's play, shot a disappointing 76 on Saturday to fall six shots off the lead.

Pep Guardiola hailed Gabriel Jesus' display in Manchester City's 5-0 win against Norwich City and said he feels fortunate to be able to work with a player as selfless as the Brazilian.

Jesus was brought into City's starting line-up as one of five changes from last weekend's defeat to Tottenham as City produced a five-star showing against Norwich.

The Brazil international was fielded to the right of a front three that also contained Ferran Torres and Jack Grealish in Saturday's Premier League clash at the Etihad Stadium.

While Jesus did not find the net, he played a game-high three key passes, which included assists for Jack Grealish and Raheem Sterling.

He also sent in the ball that led to Grant Hanley and Tim Krul inadvertently combining for City's opener and was heavily praised by Guardiola after the impressive display.

"If one person deserves respect and man of the match prizes then it's him. His mum and dad have to be so proud to have someone like him," Guardiola told BBC Sport.

Speaking at his post-match news conference, the Catalan coach added: "He's a player who likes to be wider than central position.

"One of the reasons I'm a manager is when you can work with people and humans like Gabriel. He never complains, he plays five minutes, he plays the best five minutes he can.

"He's happy on left, right or centre and today the connection with Kyle [Walker] was exceptional. I'm pleased with his performance – he was involved in three of our goals and is an incredibly important player for us.

"He made an exceptional performance today, and I repeat, if he plays three minutes he plays the best three minutes for the club and everyone. The more you have in this position the better we are. When someone plays like this they deserve to play.

"He's so young, big congratulations because he deserves in life the best. He's so generous and as I say, I'm incredibly satisfied for him."

Jesus has experience of playing in a wide role with the Brazil national team, whom he helped reach the final of the Copa America last month.

The 24-year-old was given an extended break following his Copa exploits but took little time to find his groove on his first start of the season, having been introduced as a second-half substitute against Tottenham last week.

"I play more on the right for the national team," Jesus told BBC Sport. "We have a lot of good wingers here and a very good team overall.

"I feel good and I'm getting my confidence and energy back. I like to play all the time, wherever the manager tries to play me, I try to do my best always.

"I was the last one to come back after the holidays. I didn't lose too much power. I'm a little bit lucky that I can come back, train two days or one week and get back my fitness."

Grealish, Aymeric Laporte, Sterling and Riyad Mahrez were all on target for City in their routine victory after Krul had opened the scoring win an early own goal.

Since Guardiola arrived in the Premier League at the start of the 2016-17 season, City have now been responsible for 23 of the 49 games won by a five-goal margin (47 per cent).

It was a timely win for City, ending a run of three defeats in a row in competitive games without scoring stretching back into last season.

"This result was the consequence of how many good things we have done," Guardiola said.

"We are still not at the top – there are still many things to do. We trained, we were refreshed and I'm happy for these first points.... hopefully they will not be the last!"

Grealish's goal was his first for City since arriving in a British record £100million deal from Aston Villa this month on what was his home debut and third appearance overall.

The England international knew little about the goal, with Jesus' powerful cross hitting his thigh before he could react and flying past Krul.

Citing the example of "machine" Sterling, who has built a reputation for being in the right place to finish off moves, Guardiola expects Grealish to become a regular goalscorer.

"If he gets the mentality to score goals like Raheem, yeah [he can score more]," Guardiola said. "When Raheem was here when I first arrived he didn't have goals in his mind and we immediately changed his arrival.

"Today Raheem scored because he arrives in the centre, he's a machine there. He changed his mind and decided he was going to score. Jack has this mentality to score goals and win games. If he has the Raheem mentality then he can do it, too."

South Africa are now unbeaten for five consecutive Rugby Championship matches for the first time since 2009 following Saturday's 29-10 defeat of Argentina.

The Springboks made 11 changes to the starting line-up from last week's 32-12 win and it heralded a more one-sided contest at Nelson Mandela Bay Stadium.

A first half dictated by the boot of Handre Pollard and too many cheap Pumas penalties allowed South Africa a more carefree second 40 minutes, with Makazole Mapimpi and Malcolm Marx scoring their two tries in a straightforward victory.

Pollard's penalty opened the scoring after some good early Pumas possession, before Trevor Nyakane was forced off with injury inside a quarter of an hour.

Argentina gave up eight penalties inside 25 minutes, with Pollard stretching the lead to 9-0 before Domingo Miotti kicked his side onto the scoresheet.

Pollard made it four from four as the Springboks continued to draw ill-discipline from their opponents. Referee Karl Dickson had soon had enough, sending Rodrigo Buni to the sin bin for offside, with Pollard again making no mistake with his fifth penalty before half-time.

Miotti missed his mark either side of the interval before South Africa got the first try of the contest, Mapimpi racing in down the left after a good Willie Le Roux pass at the end of a quick move.

The power of the Springbok pack was simply too much and Marx went over after another maul, Pollard adding the extras to keep up his spotless record.

With South Africa chasing a bonus point and Argentina desperate to reduce the deficit, the contest went beyond 84 minutes before Pablo Matera battled his way over the line and Nicolas Sanchez converted.

De Jager dominates on 50th cap

Lood De Jager marked his half-century for the Boks with another imperious performance as the pack once again proved too strong.

The Sale Sharks lock made seven carries and won all 14 of his tackles, having not missed any of his 16 attempts a week ago.

Pumas pay penalty

Argentina simply made life too easy for South Africa through their own lack of discipline, giving up 21 penalties to the Boks' 11.

It proved the undoing of a decent defensive effort that saw Tomas Lavanini and Julian Montoya reach double figures for tackles.
