Emma Raducanu raced into her first semi-final of 2022 by beating Magda Linette at the Korea Open, teeing up a meeting with top seed Jelena Ostapenko. 

Raducanu required just 77 minutes to see off the third seed for a 6-2 6-2 win, dominating from the outset to clinch her first final four spot in any tournament since last year's famous US Open triumph.

Having wrapped up the opener with a fierce backhand winner, Raducanu was forced to endure a brief revival from Linette in the second set, before the Pole was troubled by a thigh injury.

Linette lost 14 of the first 17 points on resumption after a medical time out, struggling with her movement as Raducanu saw out the match.

Raducanu has yet to drop a set during her run in Seoul, but will face a stern test in the semi-finals after Ostapenko overcame 17-year-old Victoria Jimenez Kasintseva 6-2 6-1, setting up a first career meeting between the duo.

On the other side of the draw, Ekaterina Alexandrova earned a hard-fought 7-5 7-6 (8-6) win over Lulu Radovcic, but fourth seed Zhu Lin crashed out to Tatjana Maria, losing 6-1 6-1.

In the Pan Pacific Open in Tokyo, meanwhile, Garbine Muguruza fell to a shock 6-4 6-2 quarter-final defeat to Liudmila Samsonova, handing the Russian her 16th win in her last 17 outings.

She will meet Zhang Shuai in the next round, after she became the first Chinese player to make the last four in Tokyo since 2009 by beating Petra Martic 7-5 6-2. 

In a battle between the competition's fourth and fifth seeds, meanwhile, Veronika Kudermetova rallied to beat Brazil's Beatriz Haddad Maia 6-7 (4-7) 7-6 (8-6) 6-1.

Naomi Osaka's title defence at her home Pan Pacific Open event came to a premature end as she withdrew from her second-round match against Beatriz Haddad Maia.

The former world number one, who won the Tokyo tournament when it was last held in 2019, was unable to compete in Thursday's match due to illness.

"I am really sorry that I am not able to compete today," Osaka said. "It's an honour to be able to play at the Pan Pacific Open in front of the amazing fans here in Japan.

"This has and always will be a special tournament for me and I wish I could have stepped on court today, but my body won't let me."

Haddad Maia advanced on a walkover and will next face fourth seed Veronika Kudermetova, who defeated Mexican qualifier Fernanda Contreras Gomez 6-0 6-1 to reach the quarter-finals.

Liudmila Samsonova also progressed to the last eight, with a 7-6 (7-5) 6-3 win over Wang Xinyu continuing her good form.

However, sixth seed Karolina Pliskova exited the competition on Thursday at the hands of Petra Martic, who prevailed 6-3 6-4 and will face Zhang Shuai next.

At the Korea Open, top seed Jelena Ostapenko recovered from two games down in the deciding set to overcome Anastasia Gasanova 6-3 5-7 7-5.

Ostapenko remains on a possible semi-final collision course with Emma Raducanu, who came through 6-4 7-5 against Yanina Wickmayer, while Magda Linette saved two match points to beat Kristina Mladenovic 4-6 7-6 (7-5) 6-2.

Naomi Osaka began the defence of her Pan Pacific Open crown with a quick win after opponent Daria Saville was forced to retire in just the second game.

Four-time grand slam champion Osaka won the opening game, before Saville was unable to continue due to a scary-looking injury to her left knee.

The former world number one will now face a second round match with world number 16 Beatriz Haddad Maia, who eased to a straight sets victory over Yuki Naito.

Karolina Pliskova secured her place in the next round in Tokyo with a 6-2 6-1 demolition of Isabella Shinikova, while Zhang Shuai will face second seed Caroline Garcia on Wednesday after overcoming Mai Hontama in two sets.

In Seoul, Jelena Ostapenko's hopes of repeating her 2017 heroics at the Korea Open are still alive after the number one seed narrowly beat 19-year-old Jeong Bo-young.

The world number 19 looked to be cruising after the opening set, but the unheralded South Korean hit back in the second and took it to a tie-break in the third, before Ostapenko's class showed as she won the crucial tie-break 7-2.

Elsewhere, 2021's beaten finalist Kristina Mladenovic saw off wildcard Park So-hyun 6-4 4-6 6-3, while second seed Ekaterina Alexandrova overcame a worrying second set to beat Asia Muhammad 6-1 3-6 6-1.

Wimbledon semi-finalist Tatjana Maria is also safely through to the second round after a tight 7-6 (7-5) 7-6 (7-5) triumph over Eugenie Bouchard.

Serena Williams highlighted the first day of the Canadian Open, defeating Nuria Parrizas-Diaz 6-3 6-4 for her first win since the 2021 French Open.

In doing so, Williams became the fourth player since 2000 to win a WTA-level main draw match after turning 40, joining sister Venus Williams, as well as Kimiko Date Krumm and Martina Navratilova.

She also claimed the all-time record for wins at the Canadian Open, with 35, now one more than Chris Evert.

"I guess there’s just a light at the end of the tunnel," Williams said after the match. "I don’t know, I’m getting closer to the light. Lately that's been it for me. I can’t wait to get to that light."

She added: "I love playing though, so it’s like amazing. But I can’t do this forever. Sometimes you just want to try your best to enjoy the moments and do the best that you can."

Williams' older sister Venus, 42, was beaten on Monday by Swiss Jil Teichmann 6-2 6-3 with the match finshing after midnight following a delayed start due to rain.

One of the three seeded players in action on Monday, 15th seed Simona Halep had no issues cruising through the challenge of Donna Vekic 6-0 6-2.

It was similarly smooth sailing for 14th seed Karolina Pliskova in her all-Czech showdown against Barbora Krejcikova, winning 6-3 6-4, while Latvian 16th seed Jelena Ostapenko handled the challenge of Ukraine's Anhelina Kalinina 6-4 6-2.

Kazakhstan's Elena Rybakina defeated in-form qualifier Marie Bouzkova 7-5 6-7 (3-7) 6-1, likely earning a shot at Coco Gauff if the American wins as a heavy favourite tomorrow, while Brazil's Beatriz Haddad Maia beat Italy's Martina Trevisan 6-2 2-6 6-2 in a meeting of two top-30 players.

In a pair of all-American battles, Sloane Stephens edged Sofia Kenin 6-2 7-6 (7-5) 7-5, and world number 187 Asia Muhammad upset world number 25 Madison Keys in straight sets 7-6 (7-5) 6-4.

Alize Cornet defeated her French compatriot Caroline Garcia 3-6 6-3 6-3, and Canada's Katherine Sebov was unable to get the job done in front of her home fans, going down 6-3 2-6 5-7 to Yulia Putintseva.

In better news for the Canadians, Leylah Fernandez won 6-4 6-7 (2-7) 6-3 over Storm Sanders, while veteran two-time Wimbledon winner Petra Kvitova was beaten by Alison Riske 6-2 4-6 6-3.

A tremendous performance from Petra Kvitova saw her ease past Jelena Ostapenko in straight sets 6-3 6-2 to win the Eastbourne International on Saturday.

Reigning champion Ostapenko had not dropped a set on the way to the final, but could not halt Kvitova, who was making her first appearance in a final in 2022.

The former world number two – and two-time Wimbledon champion – made a strong start, breaking Ostapenko early on and racing to a 3-0 lead in the first set.

Ostapenko, the Latvian number eight seed, faced eight break points in the opening set, saving seven, but she was unable to force any of her own as Kvitova comfortably served out to move ahead.

Kvitova was hitting the ball with immense power, particularly on returns, but Ostapenko showed initial improvement in the second set with her first serve accuracy, which had been down at 55.9 per cent in the first.

However, it was not enough to keep her opponent at bay as some more fierce returning from Kvitova saw her break in the third game of the second set.

Ostapenko finally threatened to break the Czech's serve, but was unable to take any of the five break points she earned in a game that lasted more than 12 minutes.

Her first serve dropped off again, which allowed the relentless Kvitova to take full advantage, breaking for a second time before serving for the championship and sealing her first-ever Eastbourne title.

It was Kvitova's 29th triumph on the WTA Tour, but her first since March 2021. Her last success on grass had come in Birmingham four years ago.

Reigning Eastbourne International champion Jelena Ostapenko will go up against Petra Kvitova in 2022 Saturday's final.

Ostapenko won as a wildcard in 2021, and the world number 14 confirmed her place in this year's showdown by overcoming Camila Giorgi on Friday.

She is the first female player to reach back-to-back finals in Eastbourne since Caroline Wozniacki in 2017 and 2018.

The Latvian, who is also going to compete for the doubles title, prevailed 6-2 6-2 and will now go up against Kvitova. The pair have faced off eight times previously, with each player winning four matches.

It is Kvitova's first appearance in a final in 2022, with the former world number two – and two-time Wimbledon champion – having ended Beatriz Haddad Maia's winning streak.

Haddad Maia won in Birmingham last week and Nottingham the week before, but her run came to an end at 12 matches, with Kvitova triumphing 7-6 (7-5) 6-4.

"For me, a final after almost a year [without one] will be great, so I’m glad already," said Kvitova, who was a runner-up at Eastbourne in 2011 and last reached a final on grass in Birmingham four years ago.

"Jelena loves to play here, obviously, we saw it, she has a really great game for grass."

Meanwhile, at the Bad Homburg Open, 2019 US Open champion Bianca Andreescu reached her sixth career final courtesy of a walkover against Simona Halep.

The Romanian withdrew from the semi-final clash with a neck injury, which will worry the 2019 Wimbledon champion ahead of the season's third grand slam at the All England Club.

"I am sorry that I had to withdraw today before my semi-final match," Halep said in a statement.

"But unfortunately I woke up this morning with a blocked neck and this is not allowing me to perform to the best of my ability."

Andreescu will face Caroline Garcia, who saved a match point before going on to beat fellow Frenchwoman Alize Cornet 7-6 (11-9) 3-6 7-5 to reach an 11th tour-level showpiece.

Bianca Andreescu dismantled top seed Daria Kasatkina to reach the semi-finals of the Bad Homburg Open, while Beatriz Haddad Maia moved a step closer to a third straight title in Eastbourne. 

A resounding 6-4 6-1 win over Kasatkina saw Andreescu advance to the last four of a WTA Tour grass-court tournament for the first time. 

The last time she reached the semi-finals in any event was the 2021 Miami Open, where she finished as runner-up after retiring with an ankle injury in the second set of the final against Ash Barty. 

Andreescu limited Kasatkina to just 17.6 per cent of the points behind the Russian's second serve and saved four of the six break points she faced to book a meeting with Simona Halep. 

Former world number one Halep sent down 10 aces and converted all three of the break points that came her way in a 6-2 6-1 success over Amanda Anisimova. 

The other semi-final will be an all-French affair after Alize Cornet and Caroline Garcia downed home hopes Angelique Kerber and Sabine Lisicki respectively. 

After going all the way in Nottingham and Birmingham this month, Haddad Maia progressed to the semi-finals of the Eastbourne International courtesy of a walkover against Lesia Tsurenko. 

Next up for Haddad Maia is Petra Kvitova, who she beat in straight sets in the first round in Birmingham, after the Czech ended Harriet Dart's run to the quarter-finals with a 6-3 6-4 win. 

Jelena Ostapenko cruised to a 6-3 6-2 victory against Anhelina Kalinina and will take on Camila Giorgi for a place in the final. Giorgi comfortably overcame lucky loser Viktoriya Tomova 6-2 6-1 in 64 minutes. 

Garbine Muguruza saw her Wimbledon preparations take a hit as she fell to a last-16 defeat at the Eastbourne International on Wednesday. 

World number 26 Camila Giorgi battled from a break down in both sets to beat fifth seed Muguruza 7-5 6-3 in an hour and 53 minutes. 

That meant 12th seed Giorgi made her second straight quarter-final, following a last-eight appearance in Birmingham, and will next face Viktoriya Tomova, who defeated Kirsten Flipkens 3-6 6-3 6-4. 

Jil Teichmann, the 10th seed at the tournament, was a notable second-round elimination, falling to a 7-6 (9-7) 4-6 6-3 defeat to Briton Harriet Dart, who later triumphed 6-4 2-6 6-4 over Marta Kostyuk. 

Dart's fellow Briton Katie Boulter stunned last year's Wimbledon runner-up Karolina Pliskova in the second round but had no such luck against Petra Kvitova, losing 5-7 6-0 7-5. 

Beatriz Haddad Maia, the winner at the Birmingham Open last week, extended to a 12-match winning streak with a 6-1 6-2 victory over Jodie Burrage. 

Jelena Ostapenko also progressed after Madison Keys retired when 6-3 down and will next face Anhelina Kalinina, who battled to a 6-3 2-6 6-3 win over 16th seed Yulia Putintseva. 

While seeds fell at Eastbourne, there were not as many shocks at the Bad Homburg Open, where Angelique Kerber defeated Lucia Bronzetti 6-2 6-3 to reach the quarter-finals. 

Fourth seed Simona Halep also made the last eight with 6-0 6-3 victory over Tamara Zidansek and will meet Amanda Anisimova after she won an All-American match against Ann Li 6-0 6-2. 

Alize Cornet downed Tatjana Maria 7-6 (7-4) 6-4 to tee up a clash with Kerber, while Bianca Andreescu will meet top seed Daria Kasatkina after defeating Katie Swan 6-4 6-4. 

Katie Boulter stunned last year's Wimbledon runner-up Karolina Pliskova at the Eastbourne International as the Briton secured the first top-10 scalp of her career.

Despite making a strong start, fourth seed Pliskova faltered and lost 1-6 6-4 6-4 to the world number 127 in the pair's last-32 match.

Boulter said: "I'm super-proud of myself today. I went out there and didn't feel great on court, and I worked so hard to battle and fight, and against a player like that it means so much to me, coming through that."

There was another major shock win for a British player later in the day as Jodie Burrage knocked out top seed Paula Badosa, the world number 169 triumphing 6-4 6-3 against a player who will be seeded fourth at Wimbledon.

Defending champion Jelena Ostapenko beat Ajla Tomljanovic 6-4 6-4 and two-time Wimbledon winner Petra Kvitova saw off Donna Vekic 6-1 7-6 (7-1), while Beatriz Haddad Maia's strong form on grass continued with a 6-4 3-6 6-3 victory over Estonian veteran Kaia Kanepi.

Brazilian left-hander Haddad Maia is coming off the back of title wins in Nottingham and Birmingham and stretched her winning run on grass to 11 matches.

There were also wins in Eastbourne for Camila Giorgi, Madison Keys and Barbora Krejcikova, but Greek third seed Maria Sakkari bowed out, losing 3-6 7-5 6-4 to Ukrainian Anhelina Kalinina.

At the Bad Homburg Open in Germany, the 2019 Wimbledon champion Simona Halep scrambled for a 4-6 6-3 6-4 win against Katerina Siniakova, and sixth seed Amanda Anisimova came from a set down to see off Alison van Uytvanck in a third-set tie-break.

Bianca Andreescu saw off Martina Trevisan 6-3 6-1 and Angelique Kerber also won in straight sets, while top seed and recent French Open semi-finalist Daria Kasatkina reached the quarter-finals with a 6-1 3-6 6-1 win over Germany's Jule Niemeier.

Kasatkina will be absent from Wimbledon due to the ban on Russian players.

Ons Jabeur held off qualifier Alycia Parks to reach the quarter-finals of the Berlin Open, saving set point before winning a competitive second-set tie-break to set up a last-eight clash with Aliaksandra Sasnovich.

Jabeur took one hour and 31 minutes to overcome her stubborn opponent in the German capital, with the world number four triumphing 6-2 7-6 (10-8) to reach her eighth quarter-final of 2022 – each of which have been at WTA 500 level or higher.

The Tunisian will face Sasnovich for a semi-final spot next time out, with the Belarusian having won 26 matches so far this year (including qualifying draws). Only Iga Swiatek (42) and Beatriz Haddad Maia (29) have more victories so far this season on the WTA Tour.

The other seeds in action in Berlin on Thursday also progressed, with Coco Gauff overcoming Wang Xinyu 6-0 6-4 to tee up a clash with Karolina Pliskova, and Belinda Bencic downing Anna Kalinskaya 6-4 1-6 6-1.

Defending champion Ludmilla Samsonova, however, suffered a 6-3 6-7 (5-7) 6-1 defeat to Veronika Kudermetova.

Meanwhile, the Birmingham Classic's top seed Jelena Ostapenko fell to a surprise 3-6 7-5 7-5 last-16 reverse against Ukraine's Dayana Yastremska, who reached her first ever grass-court quarter-final on the WTA tour.

The world number 79 will face Zhang Shuai for a spot in the final four after she fought her way to a 6-2 2-6 7-5 win over Elena-Gabriela Ruse.

Third seed Camila Giorgi will join them in the last eight after recovering from losing her first set against American Lauren Davis to secure a 3-6 7-5 6-2 win.

Berlin Open top seeds Ons Jabeur and Maria Sakkari progressed with relative ease from their first-round matches, but Aryna Sabalenka and Garbine Muguruza were not so fortunate.

World number four Jabeur, who will team up with Serena Williams at the Eastbourne International, suffered a shock first-round exit at the French Open, but the Tunisian showed no signs of that defeat having affected her in her first grass-court appearance of the season.

Top seed Jabeur required just 73 minutes to overcome Karolina Muchova 6-3 6-3 on Tuesday, with American qualifier Alycia Parks next up after she defeated Qinwen Zheng in straight sets.

Second seed Sakkari, meanwhile, had a similarly comfortable start to her campaign, beating Leolia Jeanjean 6-3 6-2.

Meanwhile, reigning champion Liudmila Samsonova took her place in round two with a 7-5 6-1 victory over Tamara Zidansek.

Samsonova beat Belinda Bencic to claim the title in 2021, and the pair will meet again the quarter-finals should they win respective second-round ties against Veronika Kudermetova and Anna Kalinskaya.

But Kudermetova goes into her clash with Samsonova on a high, having eliminated third seed Sabalenka in a 2-6 7-5 6-4 comeback victory.

WTA Finals champion Muguruza will not be in round two after the Spaniard fell foul of Germany's Andrea Petkovic, who prevailed 7-6 (10-8) 6-4.

"I really do believe that in these really close matches, the simple and little shift of energy can make the difference," Petkovic said.

"If you have the crowd on your side, and they are willing you to the win somehow, I think that can really make a difference."

At the Birmingham Classic, top seed Jelena Ostapenko booked a second-round meeting with Dayana Yastremska.

While Yastremska beat Magda Linette in straight sets, Ostapenko was made to work, with the Latvian requiring two hours to overcome Canada's Rebecca Marino 6-2 5-7 6-3.

Fourth seed Elise Mertens was ditched out by Caty McNally, while former world number two and two-time major champion Petra Kvitova lost to Beatriz Haddad Maia.

Camila Giorgi, the third seed, leads Tereza Martincova after claiming a close first set 9-7 in the tie-break before the match was suspended.

Denis Shapovalov has attacked Wimbledon and the ATP for the decisions that have led to fears of players skipping the grass-court grand slam.

Canadian left-hander Shapovalov enjoyed a run to the semi-finals at the All England Club last year, eventually losing to Novak Djokovic, but he will lose all his points and be unable to defend them at the 2022 tournament.

The season's third major will not have any ranking points after the ATP and WTA, which run the men's and women's tours, respectively, effectively decided to punish the grand slam's organisers for banning Russian and Belarusian players.

Naomi Osaka has said she is unsure about playing in London on that basis, as she wants to play events where there are points available following a slide on the WTA list, and there are concerns others may also give it a miss. A number of players have voiced concern that prize money could be slashed too.

Shapovalov, who addressed the matter after a shock first-round loss to Denmark's Holger Rune at the French Open on Tuesday, said he did not agree with the banning of players or the subsequent points decision.

"I completely understand the politics and the situation they're in. But if you have a tennis tournament that's supposed to have the best athletes in the world, it shouldn't matter where you're from," Shapovalov said.

"I also don't agree with the ATP to take out all the points. The most guys it's affecting are the guys in the top rankings."

Referring to last year's semi-finalists in the men's singles, Shapovalov, who beat Andy Murray on the way to the last four, said: "Obviously Novak [Djokovic], me, Hubi [Hubert Hurkacz], [Matteo] Berrettini, who is not playing here, we're going to drop a lot.

"I think they could have gone with it a different way, maybe keep 50 per cent like they have in the past or some kind of fairness."

Karolina Pliskova lost to Ash Barty in the women's final at Wimbledon last year, and the Czech described the WTA's move to strip points from Wimbledon as a "super tough and unfair and bad decision".

She will play Wimbledon, which starts on June 27, because she feels it is a tournament she can win, and at the age of 30 she is determined to take every opportunity going to land a maiden grand slam. She could become champion this year but, because last year's Wimbledon ranking points will fall off, plunge down the rankings at the same time.

Intriguingly, Pliskova said leading WTA stars could not agree what action tour chiefs should take about points.

"We had a group of WhatsApp chat [between] top 10 players and these 10 girls could not agree on the same thing," Pliskova said. "Some girls were for no points, some were for 50 per cent, to keep just 50 per cent from last year, some were for like all the points. So it is what it is."

Latvian Jelena Ostapenko, who won the French Open in 2017 and reached the Wimbledon semi-finals a year later, suspects there could yet be a twist in the saga to come.

Ostapenko said: "There are of course a lot of rumours and talks, but I think maybe they are going to change their mind. I'm not sure about points. But I think a lot of things may happen within the next week or two weeks.

"That's my personal opinion. Maybe I'm wrong. If there are no points, I'm not really sure what I'm going to do.

"I feel like it's a little bit unfair to play the tournament when there are no points and you can win the tournament and then you don't move one spot up in the ranking."

Emma Raducanu retired from her first-round match with Bianca Andreescu at the Internazionali d'Italia because of a lower back injury.

The world number 12 was trailing 6-2 2-1 when calling time on the match against Andreescu in a highly anticipated showdown between two of the past three US Open winners.

Raducanu initially left the court for treatment ahead of the seventh game of the opening set for a medical timeout and completed just four more games.

Speaking after her withdrawal, coming two weeks before the French Open, Raducanu explained she did not want to aggravate an injury sustained at last week's Madrid Open.

"I thought maybe taking one, two days off, it would go away because a lot of the other small niggles I've had, they've kind of gone away after taking, like, two days off," she said.

"Then I got here and I was training, but it just didn't seem to get better. I was training with some limitations. I wasn't moving really.

"I was just playing where I knew where the ball was coming, just staying in one corner. I think I must have underestimated the unpredictability of competition in a match.

"The last few weeks have been really positive. I've learned a lot about myself and my game has definitely improved on this surface but I need to make sure my back is fully right.

"I need to just keep on it. I don't want to play my next match with a feeling of limitation because I think that I learned my lesson from this week, when to push, when not to push." 

Ons Jabeur joined Andreescu in the last 32 with a 6-0 7-6 (7-1) victory over Sorana Cirstea to keep her impressive run of form going.

The Tunisian won her first WTA 1000 title in Madrid last week and has now won seven successive main draw matches for the first time in her career

Elsewhere in Tuesday's action, American qualifier Lauren Davis pulled off a shock 6-2 6-3 win against number 11 seed Jelena Ostapenko.

Fellow Americans Jessica Pegula, Madison Brengle and Amanda Anisimova also advanced, beating Liudmila Samsonova, Marta Kostyuk and Tereza Martincova respectively.

Anisimova, who is now the player with the most wins in three sets so far in 2022 with nine, will face Belinda Bencic for a place in the last 16.

Amanda Anisimova celebrated her fifth career top-10 win by beating Aryna Sabalenka again at the Madrid Open.

The 20-year-old American would have headed into Thursday's match-up full of confidence having also defeated the world number four in Charleston earlier this month.

And again Anisimova came out on top, this time at a tournament where Sabalenka was the defending champion.

Sabalenka is now 0-4 against Anisimova, losing three times on clay, with this the underdog's first ever victory in Madrid.

A 6-2 3-6 6-4 triumph was sealed in an hour and 55 minutes, with Anisimova relishing the opportunity to take on one of the sport's foremost stars once more.

"It's always enjoyable to accept the challenge, even when it's a tough match, and push yourself and see how far you can go," Anisimova said.

"I enjoy these matches, even though they're very tough – especially when you get to win them."

While Anisimova can look forward to facing Petra Martic in round two, hers was not the only upset win, with Karolina Pliskova and Jelena Ostapenko also ousted.

Pliskova lost in straight sets to fellow Czech Marie Bouzkova, as Ostapenko went down in three to Ekaterina Alexandrova.

Simona Halep and next opponent Paula Badosa both came through unscathed, though, as did Belinda Bencic, Coco Gauff and Ons Jabeur.

Jabeur's 11-9 first-set tie-break success against Jasmine Paolini was the closest any of that quintet came to dropping a set on day one.
