Nikoloz Basilashvili won a fifth ATP Tour title as he triumphed at the BMW Open on Sunday.

The Georgian completed an impressive week in Munich by beating Jan-Lennard Struff 6-4 7-6 (7-5) to clinch the trophy without dropping a set in his five matches.

The win continued what has been a solid 2021 for Basilashvili, who won the title in Doha in March after defeating Roger Federer in his second match following his return from injury.

After retiring from his opening match in Monte Carlo last month before losing to Jeremy Chardy in Barcelona, the world number 35 had looked in fine form in Munich before battling to victory against Struff in just under 86 minutes.

"It wasn't easy and I was super-tight at the end," said Basilashvili. "It was very difficult. It's never easy playing Jan, he's a very big fighter and serves really well.

"I am super happy. It seems like German conditions suit me. This is my fifth [ATP Tour] title and it will give me confidence for the upcoming tournaments."

At the Estoril Open, Albert Ramos-Vinolas emerged victorious from a marathon final against Cameron Norrie.

The 33-year-old was a set and a break down but rallied to win 4-6 6-3 7-6 (7-3) in two hours and 44 minutes in Portugal.

It was the Spaniard's third Tour title and took him to a 16-5 record on clay this season. He has at least seven more wins on the surface than any other ATP player this season.

Naomi Osaka suffered a shock second-round exit to Karolina Muchova at the Madrid Open, but there was no such trouble for Simona Halep as she held off Zheng Saisai.

Second seed Osaka was playing just her second match on clay since the 2019 French Open due to injury issues and became the latest big name to fall at the hands of Muchova.

The world number 20, who had already defeated two top-five players this season, prevailed 6-4 3-6 6-1 in a time of one hour and 49 minutes in the Spanish capital.

Osaka has now lost two of her last three matches, having been eliminated from the Miami Open quarter-finals by Maria Sakkari at the end of March.

"I think today for me it was quite different from the last time I lost in Miami, and I actually think I played much better here, so I'm very happy about that," Osaka said.

"I think what I can take away from this is that I tried my best throughout the entire match. I think tennis-wise, I felt I was too defensive in the first set.

"I wouldn't say I’m happy that I lost, but I think I learned a lot. So that's all I can hope for."

Two-time champion Halep has yet to drop a set in this year's tournament after seeing off unseeded opponent Zheng 6-0 6-4.

Halep took nine games in a row at the start of the match but, like in her opening-round win over Sara Sorribes Tormo, she had to hold off a late surge from her opponent to advance.

Next up for Halep is a last-16 showdown with Elise Mertens, who beat Elena Rybakina 7-6 (7-4) 7-5 in the last of Sunday's matches.

Fifth seed Aryna Sabalenka safely advanced earlier in the day thanks to a 6-3 6-3 win against Daria Kasatkina, while Sakkari beat Anett Kontaveit 6-3 6-1.

Sabalenka was on course to face Victoria Azarenka for a place in the quarter-finals, but the Belarussian withdrew from her match with Jessica Pegula because of a back injury.

Elsewhere, Jennifer Brady, who knocked out fellow American Venus Williams in the first round, eased past Jelena Ostapenko 6-2 6-1.

Brady faces a tricky test in the next round with Anastasia Pavlyuchenkova, who defeated sixth seed Karolina Pliskova 6-0 7-5, seeking another scalp.

Ash Barty overcame Tamara Zidansek and her own disjointed performance to reach the third round of the Madrid Open on Saturday.

The Australian triumphed 6-4 1-6 6-3 after nearly two hours on court to extend her winning streak on clay to 13 matches.

Barty will face reigning French Open champion Iga Swiatek in the next round, the 19-year-old having eased past Laura Siegemund 6-3 6-3 in a contest where she failed to take 10 match points before getting over the line.

Barty endured a more troubled contest with Zidansek, landing just 51 per cent of her first serves.

Zidansek lost the opener after a wayward forehand at 4-4 but was authoritative in the second as she won a set against a top-10 player for the first time.

However, a series of errors early in the decider allowed world number one Barty to open up a lead she did not relinquish. Barty was champion at Roland Garros in 2019 but skipped last year's Paris grand slam, so the clash with Swiatek will pit together the two most recent French Open winners.

"[It was] a really tough match," Barty said after edging out Zidansek. "I felt my margins were a little bit off. I made a lot of errors. I think I was missing in the right way, but still just a foot or two here or there makes a big difference. I felt like there were probably too many loose ones for me today.

"I don't think there was a lot in it by any means. We had a lot of close games in the first set, early in the second set. In the third, as well, there were a lot of close games. I think the response early in the third was good. I was a bit more aggressive, was able to bring the match back on my terms."

Petra Kvitova set up a meeting with Veronika Kudermetova – who knocked out defending champion Kiki Bertens – after overcoming long-time rival Angelique Kerber 6-4 7-5.

Kerber got the opening break in each set, only to drop serve in the next game, with Kvitova ultimately rewarded for powerful hitting as she ended the contest with 33 winners to her opponent's 14.

"I served very well, especially in the important points," said Kvitova, who leads the head-to-head record 8-6. "I think we really played very well. She even served very well, as well. It was tough to attack her serve."

Fifteenth seed Johanna Konta suffered a straight-sets loss to Anastasija Sevastova, while Ons Jabeur fought back to beat Sloane Stephens.

Jan-Lennard Struff is through to his first final on the ATP Tour after ending Ilya Ivashka's impressive run at the BMW Open in Munich.

Struff had lost in his previous seven semi-final appearances and it appeared the streak may continue when he quickly fell 3-0 behind against his opponent from Belarus.

However, qualifier Ivashka – who had knocked out top seed Alexander Zverev in the previous round – only managed to win two more games in the remainder of a contest that spanned 87 minutes.

A 6-4 6-1 win for Struff sets up a showdown with Nikoloz Basilashvili, who crushed Casper Ruud 6-1 6-2 to progress through from the other half of the draw.

"I am happy to have reached my first final on home soil in Germany and I will try my best tomorrow," seventh seed Struff said after Saturday's match.

Both Basilashvili and Ruud had completed their quarter-final ties earlier on Saturday, but it was the former who coped better with a quick return to action on the clay court, easing to victory in 71 minutes.

At the Estoril Open, Cameron Norrie moved a step closer to a first ATP title after withstanding a barrage of aces to overcome the big-serving Marin Cilic in two sets.

Norrie managed to save five of the six break-point opportunities on his own serve as he eventually prevailed 7-6 (7-5) 7-5. His only previous experience of a final on the ATP Tour came back in 2019, when he lost to Tennys Sandgren at the ASB Classic in Auckland.

"[Marin] was serving great and it was really tricky to get his first serve back. I am fortunate to get through and I am just happy to be in my second final," the Briton said in his on-court interview.

Albert Ramos-Vinolas is the last player standing in his way, the Spaniard battling back after losing his serve in both sets to beat compatriot Alejandro Davidovich Fokina 6-1 6-4.

Naomi Osaka quickly adapted to playing again on clay as she was among the seeds to triumph in Friday's action at the Madrid Open.

Osaka had not featured on the red dirt since a third-round exit at the 2019 French Open, missing out on competing on the surface last year due to injury.

This year's Australian Open champion stumbled out of the blocks against Misaki Doi, quickly falling 3-0 behind in the opener, but recovered from the early setback to prevail in straight sets.

The second seed hit 26 winners in a 7-5 6-2 triumph over her compatriot, who has now lost all three of their meetings on the WTA Tour.

"You obviously want to play well against a player that's from the same country," Osaka said.

"I never really know what to expect because I feel like she always plays better when I play against her, so it's a bit tough to manage controlling my emotions. But I think I was able to do it pretty well."

Simona Halep also won in her opener at the event, the third seed racing through the first set before holding off a fightback from Sara Sorribes Tormo in the second.

Halep – who needed 83 minutes to clinch a 6-0 7-5 victory – has been crowned champion twice in Madrid, the first time coming in 2016 before she returned a year later to successfully defend the title.

Aryna Sabalenka wasted little time in seeing off the challenge of Vera Zvonareva, the fifth seed producing 37 winners in a 6-1 6-2 win, her first ever in the event.

Maria Sakkari found the going much tougher before eventually ousting Amanda Anisimova, losing the first seven games in a row before rallying for a 0-6 6-1 6-4 triumph.

Daria Kasatkina was also pushed in her opener, with a 4-6 6-4 7-6 (7-1) win over Irina-Camelia Begu taking just over three hours.

Karolina Pliskova had to go the distance after falling a set behind against Coco Gauff, while two-time finalist Victoria Azarenka came out on top in a deciding set against Ekaterina Alexandrova.

In the final match on a busy day, Jennifer Brady won 6-2 6-4 in an all-American clash with Venus Williams.  

Jil Teichmann saved six match points in a stunning defeat of Elina Svitolina before Ash Barty breezed into the second round of the Madrid Open on Thursday.

Teichmann produced an astonishing fightback to beat fourth seed Svitolina 2-6 6-4 7-6 (7-5) at the Caja Magica.

Unseeded Swiss Teichmann came from a set and a break down to claim the scalp of the world number five, who squandered a commanding 5-1 lead in the final set.

Svitolina saw six match points come and go in an incredible deciding set, opportunities she was left to rue when the 40-ranked Teichmann won a tie-break to end a contest that took two hours and 33 minutes to settle.

World number one Barty extended her winning run on clay to 12 matches with a 6-2 6-1 success over Shelby Rogers.

Barty claimed her third title of the year in Stuttgart last weekend and the Australian needed just an hour to send Rogers packing, losing just two points on her first serve and not facing a single break point.

French Open champion Iga Swiatek was also an emphatic winner, easing past another American in the form of Alison Riske 6-1 6-1.

Swiatek, making her debut in this tournament, has won 16 consecutive matches on clay after blowing Riske away.

Defending champion Kiki Bertens beat 15-year-old Victoria Jimenez Kasintseva 6-4 6-0, while Petra Kvitova progressed when opponent Marie Bouzkova retired due to hand injury after the Czech won the first set.

Garbine Muguruza was forced to withdraw ahead of her meeting with Sloane Stephens due to a leg injury. Belinda Bencic, Angelique Kerber and Johanna Konta were among the other winners in the Spanish capital.

Jan-Lennard Struff and Filip Krajinovic had contrasting routes into the BMW Open quarter-finals on Thursday.

Home favourite Struff made it to the last eight of the clay-court tournament for the fourth time in his career with a 7-6 (7-3) 6-7 (0-7) 6-2 triumph over German countryman Dominik Koepfer, who had little to celebrate on his 27th birthday in Munich.

Struff recovered from 4-2 down to take the first set and racked up four straight games to seal the deciding set. He served 11 aces and staved off five break points in a match lasting two hours and 39 minutes.

"I am very, very happy that I turned around the first set," seventh seed Struff said in his on-court interview. 

"I played a not good second-set tie-break. Before [that] the set was okay, but I couldn't lock into his service games that much.

"I am very happy that I broke him I the third set and I am very happy to be through. Dominik is a good guy and a very good player."

Fourth seed Krajinovic stands in the way of Struff and a last-four berth, with the Serbian handed a walkover after last-16 opponent Yannick Hanfmann pulled out with a neck injury.

Nikoloz Basilashvili, seeded fifth, defeated Daniel Elahi Galan 6-4 6-2 to set up a last-eight clash with lucky loser Norbert Gombos, who overcame Federico Coria 6-4 6-1.

At the Estoril Open there was a battle between music collaborators as top seed Denis Shapovalov faced off against Corentin Moutet.

The duo were welcomed onto the court by the track 'Drip', which they released together last year.

On the court, it was Frenchman Moutet who managed to snare an upset victory in a 6-4 2-6 6-4 triumph against the Canadian, to score a second top-20 win of the year.

"It was a very close match," Moutet said. "I'm lucky that I won at the end. A few points decided the winner."

Next up is Albert Ramos-Vinolas, who defeated Pierre-Hugues Herbert 6-2 7-6 (7-3).

Cameron Norrie outlasted wildcard Pedro Martinez 4-6 7-6 (7-1) 7-5 to book a quarter-final against second seed Cristian Garin, who never took to the court as opponent Richard Gasquet withdrew with a left adductor problem.

Two-time BMW Open champion Alexander Zverev is hoping to enjoy further success in Munich after shaking off the rust in his opener on Wednesday.

Zverev has been managing an elbow injury and had only played three times since mid-March, swiftly departing Masters 1000 events in Miami and Monte-Carlo.

But the German is back in familiar territory on home soil and made light work of lucky loser Ricardas Berankis.

Zverev, who won the tournament in 2017 and 2018, needed just 87 minutes to claim a 6-2 6-4 victory.

"I haven't played much tennis the past few weeks, so I know I'll need to improve for the next match," he said.

"I've had success in the past and I feel good here. I've played well in the practice and hopefully I can do better on the match court."

Fellow seeds Casper Ruud and John Millman each also advanced, albeit the latter only when Guido Pella retired after the Argentine won the first set 6-4 and was 2-0 down in the second.

At the Estoril Open, Marin Cilic and Kevin Anderson will face off in an enticing quarter-final.

One-time US Open champion Cilic has a 6-1 career lead over Anderson, who has fallen to 105th in the world.

Cilic came from behind to beat Nuno Borges 6-7 (5-7) 6-4 6-4, while Anderson defeated Roberto Carballes Baena in straight sets.

Defending champion Novak Djokovic has revealed he will not play in the Madrid Open next week.

The world number one on Wednesday announced he will not take his place in the draw at the Caja Magica, where he won the title for a third time two years ago by beating Stefanos Tsitsipas in the final.

Djokovic suffered a shock defeat to Aslan Karatsev in the semi-finals of the Serbia Open on home soil last week and the 18-time grand slam champion will not be adding to his list of honours in Madrid.

He stated: "Sorry that I won’t be able to travel to Madrid this year and meet all my fans.

"It's been two years already, quite a long time. Hope to see you all next year!"

Djokovic has won 12 times and been beaten twice this season, claiming a ninth Australian Open crown in February.

The Madrid Open was not staged last year due to the coronavirus pandemic.

Alexander Bublik's status as the Estoril Open's fifth seed meant little to Pedro Martinez as the Spaniard romped to victory.

Qualifier Martinez needed just 53 minutes to see off a player ranked 57 spots above him, triumphing 6-3 6-0 to reach the second round.

He will now face Cameron Norrie, a 6-1 6-3 winner over home hope Joao Sousa in Portugal.

Marin Cilic, himself seeded sixth, might have feared going the same way as Bublik after a chastening second set against 17-year-old Carlos Alcaraz.

But the Croatian held his nerve and got the job done in a 6-3 1-6 6-4 success.

Finally, fellow seed Albert Ramos-Vinolas was relatively untroubled in overcoming compatriot Fernando Verdasco 6-3 6-3 in an all-Spanish clash.

At the BMW Open, Jan-Lennard Struff secured safe passage to the second round on home soil in Munich.

The German saw off lucky loser Andrej Martin 6-4 6-3 and the seventh seed now face Dominik Koepfer, who downed three-time champion Philipp Kohlschreiber 4-6 6-4 6-3.

Elsewhere in the draw, Nikoloz Basilashvili, seeded fifth, defeated Thiago Monteiro, while the sixth-seeded Dusan Lajovic suffered a straight-sets loss to world number 127 Mackenzie McDonald.

Wimbledon chiefs are to scrap the 'Middle Sunday' day off at the championships – and prize money for this year's tournament looks certain to be slashed.

The announcements came on the day the All England Club revealed it received £180million in insurance pay-outs after last year's tournament was cancelled due to the COVID-19 pandemic, of which around £36million went to the Lawn Tennis Association.

Chairman Ian Hewitt said that from 2022 the Sunday at the end of the first week would become "a permanent part of our tournament schedule and we will become a 14-day tournament", with the move signalling the imminent end of 'Manic Monday', when every fourth-round match was squeezed into a packed schedule.

That is regarded by many as the most exhilarating day of the tennis year, although others consider it too busy, given the number of standout matches taking place.

From next year, those matches are now set to be split across the previously fallow Sunday and the second Monday or the championships.

Hewitt said: "Yes, that second Monday of course was popular with many, but it did create significant challenges. I'm not sure it really did full justice to that day's tennis.

"To be able to spread over two days does more justice to the play at that event."

He said the tournament should "be more accessible" on that weekend, with the Sunday having previously been given over to allowing groundstaff to have time to tend the courts, which can be in need of repair after the first six days of play.

"We are now confident we will be able to look after the courts, most particularly Centre Court, without a full day of rest," Hewitt said.

He said this year's tournament "will be different from Wimbledon as we know it", and organisers are currently planning for a 25 per cent capacity attendance, albeit still hoping to get the go-ahead to admit more spectators.

When play has happened on the middle Sunday in the past, typically due to a backlog caused by several days of rain meaning the tournament has fallen behind schedule, tickets have been made available to the general public and that has led to a vibrant, often more raucous, atmosphere.

Hewitt though signalled that would not be the ticket policy going forward, saying: "It's unlikely it's going to be like Middle Sundays in the past."

The 2021 prize money for players, who must remain in a bubble during the tournament and will not be allowed to rent private houses in London, is set to hinge on how many spectators Wimbledon is allowed to accommodate. A significantly reduced attendance would hit the event hard in the pocket, meaning prize money at the level of previous years would be impractical.

It paid out £38million to players in 2019, with the men's and women's singles champions, Novak Djokovic and Simona Halep, each picking up £2.35million

The players may only learn the 2021 prize fund a matter of days before the tournament begins, with no decision expected until June. Wimbledon begins on June 28.

"It is premature to make a judgement," Hewitt said, when asked about the prize money.

Chief executive Sally Bolton said Wimbledon was "absolutely determined to be back in style" and "to bring back sport and sporting events in the way that we know them", but pandemic considerations are limiting what it can achieve.

It has not yet been decided whether spectators will need to wear face coverings while watching matches, even though restrictions on normal life in the UK are due to be lifted on June 21.

Bolton said players may feel some "frustration" given their freedom of movement will be restrained, pointing to the "single environment" for competitors being a decision reached on the basis of dialogue with the UK government and Public Health England.

John Millman outlasted Alexei Popyrin in a near three-hour marathon to progress to the second round of the BMW Open.

Eighth seed Millman was made to work exceedingly hard to avoid an early exit, eventually coming through a contest in which the two Australians faced a combined 31 break points by a 7-6 (7-3) 3-6 7-5 scoreline.

Ricardas Berankis won a 22-point tie-break in the first set to defeat Maximilian Marterer, while there were also wins for Millman's next opponent Guido Pella, Federico Coria and Ilya Ivashka.

At the Estoril Open, Kevin Anderson saved a match point at 6-5 down in the second set tie-break and turned around a 4-1 deficit in the third set to beat Frances Tiafoe 4-6 7-6 (8-6) 7-6 (7-4).

"It was obviously a very, very close match," Anderson said. "I think there were a lot of positives, a lot of really high-quality tennis, especially from midway through the second until the end of the match, I was really happy with the way I played.

"I think even if I had lost that match, obviously it's always tough losing, but I definitely felt I took a step in the right direction.

"Getting the win is a big added bonus, it gives me another opportunity to come out in a couple days' time."

Eighth seed Alejandro Davidovich Fokina beat Pablo Andujar in three sets, with Jeremy Chardy and qualifier Nuno Borges also victorious in Portugal.

Matteo Berrettini outlasted Aslan Karatsev in an entertaining Serbia Open final on Sunday to win his fourth ATP Tour title.

Karatsev stunned world number one Novak Djokovic on Saturday to reach the final, though the Russian fell just short of claiming another scalp as he slipped to a 6-1 3-6 7-6 (7-0) defeat to Berrettini.

Second seed Berrettini could not take a first championship point in a third set that went the distance, but he held his nerve to add to his previous title triumphs at the Swiss Open, Hungarian Open and Stuttgart Open.

Berrettini held serve throughout the first set and broke his opponent in the fourth and sixth games to grab an early foothold in the contest.

But Karatsev, 18 places below world number 10 Berrettini in the ATP rankings, hit back in the second set to pave the way for a tense decider in Belgrade.

The big-hitting pair, competing against each other for the first time on the tour, managed a break of serve each before Italian Berrettini had match point in a gruelling 12th game.

While Berrettini was denied by Karatsev on that occasion, the 25-year-old powered through the tie-break to complete his impressive return to form.

"This title is for my family. This is the first time that they are actually here to see me win the trophy even though it's my fourth one," Berrettini said in his on-court interview.

"This is a special one. We came a long way since I was a kid and they were bringing me everywhere, so I think they deserve to see this kind of tennis and this kind of level. I really love them.

"It's been a pleasure being here. I came here not with the best feelings. I came back from an injury and it's never easy to come back and play this kind of level, this kind of tennis."

Rafael Nadal won the Barcelona Open for the 12th time after saving a championship point in a to end Stefanos Tsitsipas' perfect record on clay this year in a thrilling final.

World number three Nadal, playing just his third tournament of the year, is gearing up for a tilt at a record-extending 14th French Open title.

By defeating the man who landed the Monte Carlo Masters title last week, Nadal showed he is moving through the gears on his favourite surface before heading to Paris.

He won 6-4 6-7 (6-8) 7-5 to maintain his 100 per cent record in finals at this tournament on home soil, but Tsitsipas was left to reflect on a missed opportunity after the 20-time grand slam champion fended off a championship point at 5-4 in the final set.

Nadal trailed 4-2 in the opening set as Tsitsipas signalled he was up for the challenge and brimming with confidence, but back came the 34-year-old to sweep up the next four games.

Tsitsipas broke first in the second set too, inching 2-1 in front, and the Greek looked every bit a warrior capable of living with the best for much of the contest.

It was a rout when these two met in the Barcelona final three years ago, Nadal dropping only three games, but here he needed to work far harder, in what was the 69th clay-court final of his stellar career.

Tsitsipas beat Nadal from two sets down in the Australian Open quarter-finals in February, so dropping the opener here was not cause for panic, but nor was gaining the early break in the second any reason to be confident he would be taking the match to a decider.

Nadal duly broke back but then let two championship points slip by in the 10th game, with Tsitsipas serving. A smash followed by a superb drop volley from Tsitsipas meant the match remained alive.

Tsitsipas could not convert 0-40 on Nadal's serve in the next game, but he won a thrilling tie-break to take the contest all the way.

There was not a solitary break point in the decider until Tsitsipas was a point away from claiming the title in the 10th game, but the King of Clay dug in to hold.

He rubbed salt in the wounds by securing the elusive break in the next game and dropped to the clay in delight after serving it out, ending a pulsating showdown that was finally settled in three hours and 38 minutes.

Sorana Cirstea claimed the Istanbul Open title without dropping a set after overcoming top seed Elise Mertens 6-1 7-6 (7-3) in the final.

Cirstea secured just her second tournament triumph on the WTA Tour – and first since Tashkent in 2008 – in a contest of two contrasting sets on Sunday.

The Romanian dominated in the opener, breaking three times as her opponent committed 16 unforced errors while failing to hold serve.

However, Mertens responded impressively to seize control of the second set, some superb groundstrokes allowing her to open up a commanding 5-2 lead.

Cirstea hit back to take the next four games in a row and while unable to serve out for the match when 6-5 up, she would not be denied a long overdue success in the tie-break.

Victory was secured with a crunching backhand winner on the first of three match-point opportunities, ending a see-saw set that had spanned 67 minutes.

Mertens had reached the final by ending a nine-match winning run for Veronika Kudermetova, who just so happened to be her doubles partner at the event in Turkey.
