Andy Murray claimed his first win over a top-five opponent since 2016 as he stunned Stefanos Tsitsipas to reach the Stuttgart Open semi-finals.

Murray started his preparations for the grass-court swing with a run to the semi-finals of the challenger at Surbiton.

He knocked off seventh seed Alexander Bublik to reach the last eight in Stuttgart but a meeting with the top seed and world number five represented a much more imposing challenge.

It was one the two-time Wimbledon champion rose to emphatically, winning a first-set tie-break and then claiming the second set in comfortable fashion to cement a 7-6 (7-4) 6-3 win, gaining revenge for his contentious five-set defeat to the Greek at last year's US Open.

Murray's previous win over a top-five opponent came in the ATP Finals six years ago, when he defeated Novak Djokovic in a year that also saw him win Wimbledon.

"I thought I did well. He served unbelievably in the first set," Murray said in his on-court interview.

"I felt like I had very few chances, but when he was creating chances on my serve, I stayed strong.

"I played a really solid tie-break and in the second set, once I was in the rallies, I felt like I was dictating a lot of the points. It was a good performance."

Murray is up to 53rd in the live ATP rankings and is bidding to get back into the top 50 for the first time since 2018. 

Standing between him and a place in the final is Nick Kyrgios, who was 7-6 (7-3) 3-0 up when Marton Fucsovics retired from their quarter-final clash.

Matteo Berrettini beat Lorenzo Sonego in three sets, while Oscar Otte won by walkover against Benjamin Bonzi.

At the Rosmalen Grass Court Championships in 's-Hertogenbosch, Daniil Medvedev saw off Ilya Ivashka 7-6 (10-8) 6-4.

Medvedev, who will soon return to world number one when the ranking points from the French Open come into effect, sees the grass-court season as a chance to cement his grip on that spot.

"I don't have many points to defend on grass and I have some to win, so hopefully I can play well, starting here," said Medvedev. "Every round is points and the higher you get, the more you need to step up."

He will face defending champion Adrian Mannarino in the semi-finals, while second seed Felix Auger-Aliassime is into a last-four clash with home hope Tim van Rijthoven after beating Karen Khachanov. 

Daniil Medvedev started his grass-court season with victory over Gilles Simon in the Rosmalen Grass Court Championships, while Hubert Hurkacz and Denis Shapovalov suffered shock defeats in Stuttgart.

Medvedev will replace Novak Djokovic at the top of the rankings next Monday and the Russian could celebrate by claiming a first title of the year in ‘s-Hertogenbosch.

The top seed, who will not compete at Wimbledon due to a ban on Russian and Belarusian players, beat Frenchman Simon 7-5 6-4 on Thursday after saving three set points and storming back from 5-2 down in the opener, setting up a quarter-final against lya Ivashka.

Felix Auger-Aliassime, the second seed, defeated Tallon Griekspoor 7-6 (7-2) 7-6 (7-5), but third seed Taylor Fritz was beaten by wildcard Tim van Rijthoven in straight sets.

Alex de Minaur and Jenson Brooksby also made early exits, losing to French duo Adrian Mannarino and Hugo Gaston respectively.

Marton Fucsovics claimed the scalp of third seed Hurkacz to reach the last 16 at the Stuttgart Open, winning 7-5 6-7 (7-) 6-3

Shapovalov also lost his opening of the grass-court season, Oscar Otte getting the better of the fourth seed 7-6 (8-6) 7-6 (7-4)

There was no such trouble for top seed Stefanos Tsitsipas, who beat Dominic Stricker 6-3 6-4, and Andy Murray accounted for seventh seed Alexander Bublik in straight sets.

Tereza Martincova got off to a winning start at the Nottingham Open, where there were three British winners on home soil on Monday.

World number 60 Martincova recorded a 7-6 (7-1) 7-5 triumph over France's Oceane Dodin to ease into the second round in Nottingham.

Heather Watson, ranked 102nd in the world, had no problems as she eased past Katie Volynets 6-4 6-2, and fellow Briton Hannah Dart followed suit by defeating Donna Vekic 6-4 6-3.

Jodie Burrage completed the first-round sweep for British women, downing Lin Zhu 7-6 (7-5) 6-4.

At the Rosmalen Grass Court Championship, top seed Aryna Sabalenka was due to face Kateryna Baindl but bad weather curtailed the day's play early.

Earlier on, Anna Kalinskaya edged out Suzan Lamens 7-6 (7-5) 6-3 in the first round, while Catherine McNally, Storm Sanders, Olivia Gadecki and Jamie Loeb were all triumphant in qualifying.

Lorenzo Sonego eased into the second round of the Stuttgart Open on Monday, while Hugo Gaston enjoyed first-round success at the Rosmalen Grass Court Championships.

Sixth seed Sonego was the headline act on Monday in Stuttgart and made light work of Benoit Paire to win 7-5 6-2.

The Italian will next face Jan-Lennard Struff after the German edged out world number 53 Marcos Giron 7-5 5-7 7-6 (10-8).

"It's my first time here, it's my first tournament on grass and I'm really happy [with] this match," Sonego said after defeating Paire.

"It's never easy to pass from clay to grass, but I enjoy it because if I serve good it is easier for me."

Struff's compatriot Oscar Otte was another first-round winner with straight-sets victory over Daniel Altmaier, while Frenchman Benjamin Bonzi breezed past Feliciano Lopez.

In Rosmalen, poor weather wreaked havoc with the schedule but France's Gaston had little trouble against South Korean Kwon Soon-woo, winning 6-2 6-1 to reach the last 16, and Andreas Seppi battled past Gijs Brouwer in the second round of qualifying.

Seppi will be hoping to make it to the main draw, where world number two Daniil Medvedev is the top seed, with Felix Auger-Aliassime and Taylor Fritz also competing.

World number one Iga Swiatek will not play the Madrid Open after suffering a shoulder injury.

The Pole is in stunning form, having won four titles in a row after prevailing in the Stuttgart Open last time out.

Before that, the 20-year-old – whose winning streak stands at 23 matches – had lifted the trophy at the Qatar Ladies Open, Indian Wells and Miami Open.

"After intense last weeks and winning four titles in a row, it's time to take care of my arm that has been fatigued since the Miami Open and I haven't had a chance to handle it properly," Swiatek, the 2020 French Open champion, wrote in a statement posted to Twitter.

"I need a break from playing so intensively in order to treat my arm well and that's why, unfortunately, I have to withdraw from the Mutua Madrid Open. 

"My body needs rest. I'm going to take some time to prepare for Rome and Paris. See you soon there.

"Hopefully, I will play in Madrid many times in the future – I'm looking forward to it."

Swiatek was due to be top seed in the Spanish capital.

World number one Iga Swiatek maintained her impressive form by seeing off Aryna Sabalenka in straight sets in Sunday's Stuttgart Open final to win a fourth straight WTA title.

Swiatek was made to work hard in Saturday's semi-final against Liudmila Samsonova as she dropped a rare set, but she was back to her imperious best against Sabalenka.

The 20-year-old prevailed 6-2 6-2 in 84 minutes to make it 23 victories in a row – only five other different players have enjoyed longer winning runs since 2000.

With her latest triumph in Germany, Swiatek has now won 30 WTA matches in 2022, compared to 36 in the whole of 2021.

She has won the Qatar Ladies Open, Indian Wells and Miami Open in straight succession, having also reached the semi-finals of the Australian Open in January.

Sabalenka, who eliminated Paula Badosa, Anett Kontaveit and Bianca Andreescu en route to the final, was the latest player to fall short in trying to stop the sublime Swiatek.

After saving a break point in the opening game, Swiatek held serve and broke her opponent in the next game before comfortably seeing out the first set.

The Pole never looked under serious threat in the second set as she took the last four games to down world number four Sabalenka, who lost to Ash Barty in this final last year.

At the Istanbul Cup, meanwhile, Anastasia Potapova beat Veronika Kudermetova 6-3 6-1 to clinch her maiden career title.

Qualifier Potapova recovered from a set down to beat Yulia Putintseva in Saturday's semi-final and was too strong for Kudermetova in what was her third career final.

Kudermetova broke Potapova early on and led 3-1 in the opening set, but the latter soon found her range and took advantage of some sloppy mistakes from her opponent.

After battling to victory in the first set, Potapova looked far more comfortable in the second as she produced a number of impressive shots en route to a breakthrough triumph.

Iga Swiatek had to come from a set down to book her place in the Stuttgart Open final with a hard-earned victory over Liudmila Samsonova.

The world number one produced a 22nd consecutive victory as she scraped a 6-7 (4-7) 6-4 7-5 win in a contest that lasted more than three hours.

The Pole will face third seed Aryna Sabalenka in Sunday's final on the German clay.

Swiatek broke early to race out to a 3-0 lead, but was pegged back by her Russian opponent, who fought hard to claim the first set on a tie-break.

The 20-year-old was looking to break the record of Serena Williams, equalling a feat of winning 28 sets in a row, but Samsonova prevented her from doing so.

It was the first time Swiatek had dropped a set since her Indian Wells Open last 16 match against Angelique Kerber in March, but she soon got back into her rhythm and clinched the second set 6-4.

She broke early again in the decider, but was once more broken back by a determined Samsonova, and Swiatek showed frustration with herself as she struggled to put away her opponent.

However, an unusually sloppy service game from Samsonova gave Swiatek another break in the 11th game of the set, which she closed out to seal her place in the final.

The other semi-final in Stuttgart saw Sabalenka overcome second seed Paula Badosa 7-6 (7-5) 6-4.

There were 14 double faults (seven each) in the match, but it was Sabalenka's big serve that ultimately led her to victory, hitting nine aces and winning 76.9 per cent of points on her first serve.

The Belarusian also saved six of eight break points faced as she ultimately eased past her Spanish opponent.

At the Istanbul Cup, third seed Veronika Kudermetova will play Anastasia Potapova in the final after seeing off second seed Sorana Cirstea in straight sets, 6-3 6-3.

Potapova had earlier come from a set down to beat Yulia Putintseva 2-6 6-2 6-2 in the other semi-final.

Iga Swiatek believes a hard-won victory over Emma Raducanu on Friday will steel her for challenges ahead after reaching the Stuttgart Open semi-finals.

World number one Swiatek landed a 21st consecutive victory as she edged out US Open winner Raducanu 6-4 6-4 in an hour and 45 minutes on the German clay.

There was plenty to admire from both players, but in the end it was another straight-sets success for Swiatek, who dropped only two games in her previous round against German Eva Lys.

It makes the 20-year-old Pole the first woman to win 28 consecutive sets on tour since Serena Williams, who did so from the 2012 US Open to the 2013 Australian Open.

Swiatek broke early in the first set to take charge, and with 19-year-old Raducanu battling a back problem the rankings leader soon got ahead in the second too.

This was Raducanu's first-ever match against a player ranked inside the WTA top 10, a peculiar statistic given she is already a grand slam champion.

Swiatek, like her opponent, knows how it feels to win a grand slam as a teenage surprise package, having triumphed as a 19-year-old at the 2020 French Open when ranked only 54th in the world.

At 4-3 in the second set of this contest, Swiatek saved two break points with clinical forehand winners out of the reach of Raducanu, shouting out in satisfaction moments later as she held serve to move a game away.

Raducanu had two more break chances in Swiatek's next service game but again could not convert as her opponent sealed victory.

Swiatek said: "I'm pretty happy that today's match was longer. Not for now, but for the future it's going to give me a lot of experience.

"Right now I want to play really aggressively, and I think this game style is going to fit the surface, and it fit the hardcourts as well."

She will face unseeded Liudmila Samsonova next after the Russian, playing as a neutral, beat Laura Siegemund 7-5 6-3.

The other semi-final in Stuttgart will see second seed Paula Badosa take on third seed Aryna Sabalenka.

Badosa was a 7-6 (11-9) 1-6 6-3 winner against Ons Jabeur, while Sabalenka fended off Anett Kontaveit 6-4 3-6 6-1.

At the Istanbul Cup, Friday saw quarter-final wins for Veronika Kudermetova and Anastasia Potapova, along with Sorana Cirstea and Yulia Putintseva.

Those results set up a semi-final on Saturday between second seed Cirstea and third seed Kudermetova, with Putintseva and Potapova also facing off.

Iga Swiatek continued her impressive form as she crushed qualifier Eva Lys at the Stuttgart Open to clinch a 20th successive win and sail into the quarter-finals.

The world number one was far too good for her opponent, as she claimed her 6-1 6-1 victory in slightly over an hour.

Swiatek, 20, last lost a match in February and has not dropped a set since Indian Wells in March, winning each of the last 26 – that is the best such run on the WTA Tour since Serena Williams won 28 successive sets between the 2012 US Open and 2013 Australian Open.

Having won each of the past three events she has entered, Swiatek is the hot favourite to make it four on the bounce in Stuttgart, where she could meet reigning US Open champion Emma Raducanu next in the last eight.

Raducanu, seeded eighth, began her campaign with an emphatic 6-1 6-2 win over Australia's Storm Sanders on Wednesday to set up a second-round clash with Tamara Korpatsch – the winner faces Swiatek.

Sixth seed Karolina Pliskova overcame compatriot Petra Kvitova 6-4 4-6 7-6 (7-5) to progress, while Anett Kontaveit – the fifth favourite – saw off Angelique Kerber 3-6 6-4 6-4.

It was a bad day for some of the higher seeds in the Istanbul Cup, as three of the top five were eliminated.

Favourite Elise Mertens retired from her tournament opener with Rebecca Peterson due to a leg injury, though the Belgian was already 7-5 4-1 down.

Anhelina Kalinina and Jil Teichmann – seeded fourth and fifth, respectively – suffered surprise defeats as well.

Defending champion and second seed Sorana Cirstea appeared in danger of following them out as well, but rallied to defeat Arantxa Rus 3-6 6-1 7-5.

Ajla Tomljanovic also progressed, the Australian enjoying an impressive start against her countrywoman Jaimee Fourlis, winning 6-1 6-3.

Second seed Sorana Cirstea breezed through the first round of the Istanbul Cup on Tuesday as US Open champion Emma Raducanu prepares for her bow in the Porsche Tennis Grand Prix.

The Romanian made short work of lucky loser Kamilla Rakhimova in a 6-4 6-1 straight sets victory in Turkey to launch her defence of the title she won against Elise Mertens last year.

The Belgian – top seed once again in Istanbul – gets her campaign underway against Sweden's Rebecca Peterson on Wednesday.

Elsewhere, there were wins for seeds Veronika Kudermetova and Jil Teichmann, though Tereza Martincova is out after a surprise 6-4 7-5 loss to qualifier Anna Bondar.

World number 12 Raducanu meanwhile is also poised to get her latest tilt for silverware underway in Stuttgart in midweek, with the eighth seed facing qualifier Storm Sanders.

The title is up for grabs on the WTA Tour following Ash Barty's retirement, with her world number one successor Iga Swiatek a potential quarter-finalist for the Briton if she gets that far.

There will be no Coco Gauff in the mix however after the American made a first round exit in straight sets, losing to Daria Kasatkina 6-4 6-2.

Seventh seed Ons Jabeur, meanwhile, fought back to beat Marketa Vondrousova 4-6 6-2 6-3, while qualifier Eva Lys overcame Viktorija Golubic 5-7 7-5 7-5 to set up a second round clash with Swiatek.

Emma Raducanu has revealed the responsibility for her new-found affinity for Tottenham lies predominantly with her Spurs-obsessed support team.

Social media has been abuzz on Monday with photos and videos of the 19-year-old US Open champion training in a Tottenham jersey ahead of the Stuttgart Open.

The shirt even had her name and the number 10 emblazoned across the back, suggesting a particularly strong connection with the north London club. But it is not quite as it seems.

Raducanu, who was born in Toronto but raised in south-east London, said she has been heavily influenced by those close to her – although the presence of star duo Harry Kane and Son Heung-min was also a consideration.

"My whole team basically are big Spurs fans and I feel like they're egging me on," Raducanu told reporters.

"They're desperately trying to get me behind them! I don't necessarily follow football much, but I feel like now, because of them, I'm feeling some sort of connection.

"I loved following the Euros last year and watching Harry Kane, who's obviously the England captain, and Son, I'm a big fan of him as well. So yeah, I like to dabble."

Raducanu is seeded eighth for her first-ever tournament on clay this week and will begin her campaign against Storm Sanders on Wednesday.

While Raducanu's immediate aim is undoubtedly building momentum, she sees this tournament as a chance to make a statement on a surface she believes will be her strongest in the long term.

"It's going to be an exciting clay season," she added. "I'm not sure how it is going to go. I keep telling everyone around me that one day clay is going to be my surface and I still believe that.

"I think game-wise on clay, especially when you're playing outside, you definitely need to be a lot more patient and build the point.

"You can't just hit a big shot, whereas on a hard court, you might be able to get a weak shot straight away. You really need to build the point a lot more, which takes a lot more energy and physical demand.

"You just have to be more crafty, I think, and I think it's a good lesson, especially for someone younger like me, to develop more skills. 

"I'm looking forward to spending more time on the clay as the years go by because I do like sliding and moving on it, and it's just about again being able to repeat over and over."

There were two first-round matches played in Stuttgart on Monday, with Liudmila Samsonova claiming a double bagel when beating Chloe Paquet 6-0 6-0, while Ekaterina Alexandrova defeated Shuai Zhang 7-6 (7-5) 7-6 (8-6).

There were no shocks at the Stuttgart Open on Tuesday as Marin Cilic and both seeds advanced.

The grass-court swing got under way with four main-draw matches but little drama in Germany.

One-time Wimbledon finalist Cilic staved off the only two break points he faced against wildcard Rudolf Molleker and seized all five opportunities of his own.

A 7-5 6-3 win was enough to set up a second-round meeting with fifth seed Nikoloz Basilashvili, who beat Dustin Brown in the top half of the draw.

The defeated pair were the only home hopefuls in action, while number six seed Ugo Humbert and Lloyd Harris each also progressed.

Ash Barty came from a set down for the third time this week as the world number one continued a superb 2021 with victory at the Stuttgart Open.

Barty overcame Aryna Sabalenka 3-6 6-0 6-3 to lift an 11th career title and her third of the season after successes at the Miami Open and the Yarra Valley Classic in Melbourne.

It proved to be another comeback triumph against a top-10 opponent for Barty, who saw off Karolina Pliskova and Elina Svitolina in the quarter and semi-finals respectively.

Sabalenka was ready to seize upon another sluggish Barty start and forced three break points at 3-2 in the opener.

The Australian was able to hang on that time, but Sabalenka fashioned two more and a botched Barty drop shot meant it was fifth time lucky.

The rapid progress of set two suggested Barty had merely been warming up, snaffling her third break point at 1-0 and dispatching a magnificent forehand cross-court winner to surge 4-0 ahead.

A bagel felt inevitable from that point and, after a 20-minute second set, Sabalenka was sinking without a trace when she slipped 3-0 behind in the decider.

The fifth seed broke back before being undermined by an untimely double fault at 3-2 – one of 39 unforced errors – and Barty faced down three break points in the following game.

A superb display, featuring 26 winners and five break points converted from 12 opportunities, concluded when Barty wrapped things up on her second match point.

Ash Barty will meet Aryna Sabalenka in the Stuttgart Open final after Simona Halep's quest to win the tournament for the first time fell short.

World number three Halep had claimed straight-set wins over Ekaterina Alexandrova and Marketa Vondrousova en route to the semi-finals, but met her match in the form of Belarusian Sabalenka, who triumphed 6-3 6-2.

A nine-time singles champion, Sabalenka made it into a 14th career final without conceding a single break, as she managed to keep Romanian Halep at arm's length.

Standing between Sabalenka and a 10th singles title is world number one Barty who, on her 25th birthday, came from behind to defeat Elina Svitolina 4-6 7-6 (7-5) 6-2.

Making her tournament debut in Stuttgart, Barty had overcome Laura Siegemund and Karolina Pliskova, but found herself at 5-4 down in the second set, with Svitolina serving for the match.

The fourth seed failed to take her chance, with Barty breaking and subsequently biting back in the tie-break, before carrying the momentum into the decider to claim a third straight win over Svitolina.

Top seed Elise Mertens made it to her second Istanbul Open as she saw off her doubles partner and birthday girl Veronika Kudermetova 6-1 6-4.

It means Mertens will be playing in two finals on Sunday, as she pairs up with Kudermetova again in the doubles showdown against Nao Hibino and Makoto Ninomiya.

Mertens' win ended Charleston champion Kudermetova's nine-match winning streak, and set up a final against the unseeded Sorana Cirstea, who defeated Marta Kostyuk 6-4 6-4.

World number one Ash Barty survived a scare to reach the semi-finals of the Stuttgart Open with a 2-6 6-1 7-5 win over Karolina Pliskova.

The Australian started slowly in the quarter-final of the WTA 500 tournament on Friday as Pliskova broke her serve twice in taking the first set, before Barty hit back with three breaks of her own to force a decider.

Barty was two points away from losing on five occasions as world number nine Pliskova served for the match at 5-4 in the final set.

But she broke the Czech's resolve eventually, sealing victory when Pliskova hit the ball long after a baseline rally.

The win was Barty's eighth consecutive victory over a top-10 opponent and she said in a media conference afterwards that facing top players in the world brings the best out of her.

"When you come up against top-10 opponents, you have to go to that level above to be able to compete. They force you to bring your best," Barty said.

"With a lot of the girls in the top 10, we've had plenty of matches that have gone either way, different experiences, so each time I love that challenge of testing myself against the best."

Barty will face Elina Svitolina in the semi-finals after she saved two match points to claim a 6-7 (4-7) 7-5 6-2 victory over Petra Kvitova.

In the other half of the draw, Simona Halep breezed through to the semi-finals with a 6-1 6-4 win over Ekaterina Alexandrova.

Halep clinically closed out the first set, and although Alexandrova showed more fight in the second, the world number three did not allow her a route back into the match.

Halep will face Aryna Sabalenka following the Belarusian's 7-5 4-6 6-1 win over Anett Kontaveit.

In the Istanbul Cup, top seed Elise Mertens secured her place in the semi-finals with a 6-4 6-4 win over Katerina Siniakova.

Mertens will face Veronika Kudermetova who fought back from a set down to clinch a 2-6 6-3 6-3 win over Ana Bogdan.

The other semi-final will see Sorana Cirstea play Marta Kostyuk. Cirstea progressed after Fiona Ferro, trailing 6-4, retired through injury while Kostyuk beat Ana Konjuh 7-5 4-6 6-3.
