Garbine Muguruza and Alize Cornet both fell at the first hurdle at the Lyon Open on Monday, going down to Linda Noskova and Camila Osorio respectively.

Having gone out in the first round at the Australian Open earlier this month, former world number one Muguruza did the same in France, suffering a resounding 6-1 6-4 defeat to 18-year-old Czech qualifier Noskova.

Third seed Cornet did not fare much better on home soil, capitulating after drawing level with Osorio as the Colombian triumphed 6-4 4-6 6-1.

The other seeds in action on day one at the WTA 250 event avoided the same fate, with fifth seed Anastasia Potapova beating Marina Bassols Ribera 4-6 6-1 6-2 and fourth seed Petra Martic fighting back to edge her two-hour battle with Kristina Mladenovic 3-6 6-3 7-5.

At the Thailand Open in Hua Hin, third seed Wang Xiyu was beaten in an all-Chinese meeting with Zhu Lin, while Wang Xinyu triumphed in straight sets against Joanne Zuger and Ukraine's Lesia Tsurenko eliminated Ysaline Bonaventure.

Petra Kvitova defeated Elena Rybakina in the pick of the first-round matches at the Adelaide International 2 on Monday.

Two-time Wimbledon winner Kvitova hit 21 winners to 12 unforced errors on her way to a 6-3 7-5 win against reigning SW19 champion Rybakina in a match lasting 87 minutes.

Belinda Bencic, a defeated finalist in this tournament in 2021, also advanced with a 6-3 6-4 win against former world number one Garbine Muguruza to maintain her positive form.

Fellow seeded players Beatriz Haddad Maia and Danielle Collins beat Sorana Cirstea and Karolina Pliskova respectively to book their places in the last 16.

At the Hobart International, favourite Marie Bouzkova saw off Jacqueline Cristian 7-6 (7-2) 6-3, while Lauren Davis defeated Sloane Stephens 6-2 6-2 in an all-American clash.

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.

The top two seeds were eliminated in the second round of the Pan Pacific Open in Tokyo as Paula Badosa and Caroline Garcia both crashed out on Wednesday.

Badosa was defeated in just 78 minutes by Zheng Qinwen, with the number one seed going down 6-3 6-2.

It was 19-year-old Zheng's first completed win against a top 10 opponent in her career, and she said afterwards: "Even though the score was like this, there were a lot of emotions for me in this match and I'm very proud of myself. It's not a surprise. I always knew I had the level, I just had to make it."

Second seed Garcia hit 27 aces in her match against Zhang Shuai, the most in a single WTA-level contest since Kristyna Pliskova against Monica Puig in Luxembourg 2019 (28), but it was not enough as she lost two tie-breaks to lose 4-6 7-6 (7-5) 7-6 (7-5).

Number three seed Garbine Muguruza had more success as she beat Greek opponent Despina Papamichail 6-4 6-2, while Claire Liu also eased to a win against Elise Mertens 6-4 6-1, and will play Zheng in the quarter-finals.

Eighth seed Elena Rybakina suffered a first-round exit as she lost to Liudmila Samsonova 6-2 6-4, who will play Xinyu next.

The seeds fared better over at the Korea Open, with Emma Raducanu sealing a first-round win against Moyuka Uchijima 6-2 6-4, while Magda Linette also eased past Arianne Hartono, 6-2 7-5, though fifth-seed Varvara Gracheva was knocked out by Anna Blinkova 6-4 7-6 (7-1).

In the second round, third seed Ekaterina Alexandrova is through after beating Han Na-lae 6-1 6-3, as is Lin Zhu of China following her straightforward 6-1 6-3 victory against India's Ankita Raina.

There were also wins for Tatjana Maria against Kimberly Birrell, and 17-year-old Andorran Victoria Jimenez Kasintseva against eighth seed Rebecca Marino.

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. 

Garbine Muguruza recorded a much-needed win to reach the last 16 at the Eastbourne International.

World number 10 Muguruza, who had only won two tour-level matches since the start of March, was tested in a gripping second-set tie-break by Magdalena Frech, eventually triumphing 6-1 7-6 (9-7).

After the victory, Muguruza said she was pleased to have overcome challenging weather conditions to reach the next stage, saying: "I feel like I fought hard against the wind, and I haven't played many matches on grass either.

"I could see today that if I didn't fight as hard as I can, I wasn't going to win."

A minor upset saw 17th seed Alison Riske slip to a 6-7 (3-7) 6-3 7-6 (7-4) loss to Magda Linette, while Yulia Putintseva surged to a 7-5 6-1 win over Sara Sorribes Tormo and seventh seed Barbora Krejcikova saw her contest with Marta Kostyuk halted by darkness at one set apiece.

Ajla Tomljanovic beat Aleksandra Krunic 6-0 4-6 6-3 and Heather Watson went down 7-6 (7-1) 6-4 to Canada's Rebecca Marino, as the Sussex crowds prepared for Serena Williams' eagerly anticipated doubles outing alongside Ons Jabeur on Tuesday.

There was frustration for Muguruza's fellow former Wimbledon champion Angelique Kerber at the Bad Homburg Open.

Kerber's match against Anastasia Gasanova got under way, but play was stopped due to fading light and a damp court after a rain-hit day. Third seed Kerber led 4-2 in the first set of a contest that will conclude on Tuesday.

The only other seed in action in Germany made routine progress, as France's Alize Cornet raced to a 6-2 6-4 win over Anna Kalinskaya.

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.

Kaia Kanepi kept up her strong record against grand slam seeds as she overcame Garbine Muguruza at the French Open.

Muguruza won at Roland Garros in 2016 and also triumphed at last year's WTA Finals.

However, the world number 10 fell to the unseeded Kanepi in her first-round match on Sunday.

Muguruza, seeded 10th, lost 2-6 6-3 6-4 to the Estonian world number 46, who recorded her 10th career win at a major over a player ranked inside the top 10.

Kanepi, who is the oldest player in the women's main draw, also extended her brilliant record against seeds in grand slam tournaments, having now won 19 such matches.

Among active players, only Serena Williams (29), her sister Venus (22) and French Open 10th seed Victoria Azarenka (21) have more such wins.

She will now play Brazilian Beatriz Haddad Maia in the second round.

Karolina Pliskova reached her maiden quarter-final of the season after battling past Bernarda Para in Strasbourg 6-3 1-6 6-1.

Runner-up to Ash Barty at Wimbledon last July, Pliskova has endured a stop-start 2022 campaign.

The Czech missed the first two months with a hand injury, while suffering first-round exits in Indian Wells, Miami and Madrid.

But despite being taken to a decider by her French opponent, the top seed hit 16 aces on the way to reaching the last eight.

Second seed Angelique Kerber also required a deciding set to progress to her first quarter-final of the campaign; the three-time Grand Slam winner overcoming Aliaksandra Sasnovich 6-2 3-6 6-4.

Fourth and ninth seeds Elise Mertens and Viktorija Golubic also advanced to the last eight following straight-set wins over Anna-Lena Friedsam and Fiona Ferro respectively.

However, there was no joy for top seed Garbine Muguruza over in Rabat; the two-time Grand Slam champion was beaten 2-6 6-4 6-1 by world number 85 Martina Trevisan.

The Italian's reward is a quarter-final showdown with seventh seed Arantxa Rus, who saw off Dalma Galfi 6-4 6-2.

Mayar Sherif was another seed to tumble; the Karlsruhe champion lost 4-6 7-6(5) 6-1 to Claire Liu, who triumphed in the Trophee Lagardere last week.

Third seed Nuria Parrizas Diaz recovered from losing the opening set to defeat Kristina Mladenovic 4-6 6-3 6-0, while Anna Bondar hit seven aces as she overcame Kristina Kucova 6-3 6-3. 

Top seeds Karolina Pliskova and Angelique Kerber strolled to straight-sets wins in the first round of the Internationaux de Strasbourg, keeping the two former world number ones on course for a final meeting.

Having endured an injury-hit season to date, world number eight Pliskova made the perfect start to her campaign in France with a routine 6-4 6-2 win over Ukrainian 19-year-old Marta Kostyuk. 

Kerber, who is only missing a victory at the French Open – which begins later this month – to complete a Career Grand Slam, overcame teenager Diane Parry 6-3 6-4 in her opener, setting up a round-of-16 clash with world number 45 Aliaksandra Sasnovich.

Some of the other big names participating in Strasbourg, however, were not so lucky, with 5th and 6th seeds Shuai Zhang and Sloane Stephens crashing to first-round exits.

Shuai went down 6-2 6-3 to Belgium's Maryna Zanevska and Stephens capitulated to a 2-6 6-4 6-1 loss to Nefisa Berberovic, while Heather Watson set up a last-16 meeting with eighth seed Magda Linette by beating Katharina Hobgarski 6-4 6-1.

Meanwhile, Garbine Muguruza made a winning start to her campaign at the Grand Prix Sar La Princesse Lalla Meryem in Morocco, as the world number 10 builds towards a tilt at French Open glory having triumphed at Roland Garros back in 2016.

Muguruza had few difficulties in beating Anna Danilina 6-3 6-2, and will face Martina Trevisan in the round-of-16 after the Italian beat China's You Xiadoi 6-0 6-4.

Third seed Nuria Parrizas-Diaz had to come through a more difficult challenge in Rabat, overcoming Carol Zhao 7-6 (7-4) 1-6 6-2, while eighth seed Anna Kalinskaya was the highest-ranked player to fall at the first hurdle, going down 6-3 6-7 (5-7) 6-3 to Lucia Bronzetti.

Iga Swiatek and Paula Badosa progressed to the third round of the Internazionali d'Italia with ease as the former continued her impressive winning run on Wednesday.

Top seed Switaek, seeking a fifth consecutive title, breezed past Elena-Gabriela Ruse 6-3 6-0 as she became the first female player to win 24 consecutive matches since Serena Williams in 2015.

Badosa followed suit by dispatching Aliaksandra Sasnovich 6-2 6-1 in just an hour and 17 minutes, teeing up a third-round clash with Daria Kasatkina, who beat Leylah Fernandez 4-6 6-3 7-6 (7-2).

Aryna Sabalenka, the third favourite in Italy, also made light work of Zhang Shuai to triumph 6-2 6-0, while fourth seed Maria Sakkari cruised past Madrid Open semi-finalist Ekaterina Alexandrova 6-3 6-2.

Sakkari will next face a Rome rematch with Coco Gauff, who defeated compatriot Madison Brengle 6-2 6-4. Teenager Gauff's sole win against Sakkari came at this tournament in the second round last year.

Yulia Putintseva came from behind to beat Garbine Muguruza 3-7 7-6 (7-4) 6-1, and will next meet Ons Jabeur, who made it eight successive main-draw wins by defeating Ajla Tomljanovic 7-5 6-2.

Seventh seed Danielle Collins also battled past former world number one Simona Halep 7-6 (7-1) 6-3.

There was no such joy for fifth seed Anett Kontaveit as she crashed out to Petra Martic in straight sets, while Jil Teichmann upset former Rome champion Karolina Pliskova in a three-set thriller.

Belinda Bencic, who was ranked as 12th seed, was another early casualty as she fell to a 7-6 (7-4) 6-1 defeat against American Amanda Anisimova.

Meanwhile, Jessica Pegula secured her third-round spot after Anhelina Kalinina withdrew due to injury, with Victoria Azarenka earning a straightforward 6-2 6-4 victory over Camila Osorio to get a shot at favourite Swiatek in the next round.

Naomi Osaka joined several other big names in falling to a second-round exit at the Madrid Open, although Emma Raducanu cruised to a routine straight-sets win over Marta Kostyuk.

Four-time grand slam winner Osaka crashed to a resounding 6-3 6-1 loss to Spain's Sara Sorribes Tormo, exiting her first tournament on clay since the 2021 French Open, where she withdrew citing mental health issues.

Osaka, who had posted an underwhelming 20-15 record on the surface prior to this week, looked uncomfortable throughout and appeared to struggle with a leg injury during a disappointing second set display.

The 24-year-old was not the only high profile player to be on the receiving end of a shock during a day of drama in the Spanish capital, as several of the competition's seeds failed to secure places in the last 16.

Another home favourite, Garbine Muguruza, fell to a resounding loss of her own as Anhelina Kalinina raced to a 6-3 6-0 victory over the seventh seed, while sixth seed Danielle Collins was thrashed 6-1 6-1 by Canadian Bianca Andreescu.

Fourth seed Maria Sakkari was the highest-ranked player in action, and although the world number five won the first set of her clash with Daria Kasatkina, the Greek eventually fell to a 3-6 6-3 6-1 loss, while 2021 US Open runner-up Leylah Fernandez went down 6-4 6-4 to Jil Teichmann.

One big name who did make comfortable progress, however, was Fernandez's US Open conqueror Raducanu, who eased to a 6-2 6-1 win over Kostyuk to set up a last-16 encounter with another Ukrainian in Kalinina. 

The 19-year-old, who has been quoted as saying she believes clay could prove to be her best surface in the future, was delighted with her victory and enjoying the tournament after dropping just one game in the second set.

"I'm definitely happy with my performance," Raducanu said on court. "Marta's a great opponent - I knew it was going to be a really tough battle. I went out there trying to be really aggressive and it paid off.

"It's my first clay court season and I'm really enjoying it. Madrid is such a cool city and it's got such a great vibe about it. I definitely want to try and stay here for as long as possible."

Alison Riske produced a breathtaking comeback to beat Garbine Muguruza at the Indian Wells Open, turning around an apparent lost cause after losing the first nine games of the match.

Muguruza, who won the WTA Finals title at the end of last season, was cruising at 6-0 3-0, but 31-year-old American Riske, despite tossing her racket in frustration, refused to give up. Incredibly, she won 12 of the next 13 games to reach the third round at the expense of the world number nine.

"After the first set, it literally could not get any worse," Riske said in her on-court interview following a 0-6 6-3 6-1 success.

"So if I could try to get two balls in the court we might get somewhere. I was just trying to hang in there. I've played Garbine many times before and it's always been a battle."

This was Riske's fifth match against Spanish star Muguruza, and despite losing the first two of those, she had since beaten the two-time grand slam winner twice, albeit most recently at the 2019 US Open.

"I felt if I could get in there a little bit, I was going to have my chances," Riske said. "I know I've beaten her before, and if I could just bring out some of my game, good things were going to happen."

It was world number 53 Riske's 10th career victory against a player ranked in the top 10.

British player Harriet Dart pulled off a shock win over Ukrainian Elina Svitolina, as the world number 122 snatched a 2-6 6-3 6-3 victory over the 12th seed.

Three of the biggest names in the draw took the long route through to the last-32 stage, with Emma Raducanu, Simona Halep and Iga Swiatek taken to a deciding set in their opening matches, having benefited from first-round byes 

Raducanu fended off Caroline Garcia 6-1 3-6 6-1, while Halep was a 6-2 4-6 6-2 winner against Ekaterina Alexandrova, the Russian who is playing under a neutral flag.

Polish third seed Swiatek put a slow start behind her to beat Ukrainian Anhelina Kalinina 5-7 6-0 6-1 and is looking to build on her recent Qatar Open triumph. She said: "I'm pretty happy I could turn my head on to fight mode and stay focused, because that was the key I guess."

Last year's Wimbledon runner-up Karolina Pliskova bowed out, the Czech seventh seed losing 2-6 7-5 6-4 to Danka Kovinic of Montenegro.

Two of the top three seeds crashed out of the WTA Qatar Open in the round of 16 as Barbora Krejcikova and Paula Badosa both lost, though top seed Aryna Sabalenka is through to the quarter-finals, along with Coco Gauff.

Sabalenka eased past Jil Teichmann 6-2 6-1 in Doha, winning an impressive 70 per cent of her second serves as she rarely gave her Swiss opponent any hope in a match that lasted just over an hour.

The Belarusian will now play Iga Swiatek in the last eight after the seventh seed beat Daria Kasatkina 6-3 6-0.

Number two seed Krejcikova was eliminated by the winner in Dubai last week, Jelena Ostapenko, 6-3 6-2. The Czech struggled to get going and ended the match with seven double faults to her name.

World number four Badosa fared no better as she also lost in straight sets to Gauff 6-2 6-3, with the 17-year-old winning a dominant 77.1 per cent of points on her first serve.

Badosa is the joint-highest ranked player that Gauff has defeated, along with Naomi Osaka, who was also ranked fourth in the world when she lost to the teenager at the 2020 Australian Open.

Gauff will now face Maria Sakkari after the Greek defeated another American, Jessica Pegula.

Ostapenko will go up against reigning WTA Finals champion Garbine Muguruza who convincingly defeated Madison Brengle 6-0 6-2.

Number four seed and St Petersburg champion Anett Kontaveit is through after a topsy-turvy clash with Elise Mertens 6-3 0-6 6-2 and will come up against Tunisia's Ons Jabeur.

Elina Svitolina and Simona Halep both fell in the first round of the Qatar Ladies Open, while Garbine Muguruza and Anett Kontaveit eased through on Monday.

Former world number one Halep, champion in Qatar back in 2014, was off the pace as Caroline Garcia claimed just her second win in nine meetings against the Romanian with a 6-4 6-3 triumph.

Number 10 seed Svitolina also suffered an early exit after ending up on the wrong side of an almost three-hour slog, with Tereza Martincova eventually succeeding 6-7 (2-7) 7-5 7-6 (7-5).

But fifth favourite Muguruza – a two-time finalist, including in 2021 – did not have much as trouble as she outfought Sorana Cirstea 7-6 (7-4) 6-1 in a second-round contest, with Kontaveit coasting through to round three in similar fashion with a 6-2 6-3 win over Ana Konjuh. 

Jelena Ostapenko, who is a former finalist in Doha and champion in Dubai last week, managed a sixth consecutive victory in the Middle East as she downed Oceane Dodin 6-4 6-2 to reach the second round, while 11th seed Elena Rybakina fell at the first hurdle to Jacques Cristian in a 6-4 6-3 loss.

Angelique Kerber, the 13th ranked player at the tournament, was another surprise first-round loser as she fell 4-6 6-3 6-2 to Jil Teichmann.

Cori Gauff secured her spot in the second round with a straightforward 6-2 6-3 victory over American compatriot Shelby Rogers, while 16th seed Elise Mertens battled to a 6-3 2-6 7-5 win over Jasmine Paolini.

Meanwhile, defending champion Petra Kvitova had no trouble easing past Irina-Camelia Begu 6-3 6-1, and Daria Kasatkina edged out Ajla Tomljanovic 6-4 6-7 (4-7) 6-2.
