Emma Raducanu has earned direct entry into the main draw at the Australian Open following a number of late withdrawals.

The 2021 US Open champion made a winning return to the court at the ASB Classic in Auckland on Tuesday after being sidelined since April following operations on both her wrists and one ankle.

It appeared that Raducanu was going to be required to go through qualifying for the Australian Open due to her protected ranking – given to players who have been sidelined long term – not being high enough.

However, the Australian Open announced in a post on X, formerly Twitter, on Wednesday that the 21-year-old would take the place of American Lauren Davis in the main draw after the American withdrew due to a shoulder injury.

Davis joins French Open finalist Karolina Muchova, Irina-Camelia Begu and Caty McNally on the withdrawal list.

Two-time Wimbledon champion Petra Kvitova has also withdrawn from the tournament after announcing she is pregnant with her first child.

Aryna Sabalenka is through to the round of 32 at the Madrid Open after beating Sorana Cirstea 6-4 6-3 on Thursday.

It was an ominous start for Cirstea, being broken to love in the opening game, but she stuck with second seed Sabalenka and broke back, before ultimately being pipped to the first set by the impressive Belarusian.

The key was on break points, with Sabalenka claiming all five that she won against the Cirstea serve, while saving six of eight on her own as she ultimately eased to victory.

Sabalenka now has 26 wins on clay in the WTA since 2021, with only Ons Jabeur (37), Iga Swiatek (34), Paula Badosa (31) and Coco Gauff (28) having more during this time.

Gauff also advanced after a routine 6-4 6-1 win over Irene Burillo Escorihuela, making the sixth seed in Madrid the first player to win 35 WTA-1000 main draw matches as a teenager since 2009.

Ninth seed Maria Sakkari defeated Arantxa Rus 6-4 6-4 and fifth seed Caroline Garcia also had few problems against Yulia Putintseva, winning 6-3 6-4.

However, it was not a good day for 10th seed Petra Kvitova, who was beaten 7-6 (11-9) 6-1 by Jule Niemeier, while 13th seed Beatriz Haddad Maia also lost, 7-6 (8-6) 6-3 to Mirra Andreeva and 20th seed Donna Vekic was eliminated in straight-sets by Rebeka Masarova.

Jelena Ostapenko took just 61 minutes to get past Linda Fruhvirtova 6-0 6-3, and will face 14th seed Liudmila Samsonova next, who did not take much longer to see off Maryna Zanevska 6-2 6-3.

There were also wins for Elise Mertens, Badosa, Camila Osorio, Shelby Rogers, Mayar Sherif, Magda Linette and Irina-Camelia Begu.

Elena Rybakina's superb run in the United States was ended by Petra Kvitova, who won 7-6 (16-14) 6-2 to clinch the Miami Open title.

Two-time grand slam champion Kvitova, 33, became the second-oldest Miami champion, denying young gun Rybakina a Sunshine Double in the process.

Rybakina, fresh from her triumph at the Indian Wells Open, has been in stunning form but could not find her groove on Saturday.

After clinching the first set following a marathon tie-break, Kvitova took momentum into the second, cruising into a 5-2 lead before sealing the win with a break – Rybakina sending a forehand long.

Kvitova equalled Simona Halep as the players with the third-most WTA 1000 titles (nine), with only Serena Williams (13) and Victoria Azarenka (10) having won more since 2009.

"It feels unbelievable. I'm 33, and it's my 30th title, so I'm very happy," Kvitova told Amazon Prime Sport.

"I didn't think, that was the key. Elena didn't lose a tie-break [this season]. I thought, well, she has to lose at some time. I had to be a bit more aggressive, it was a bit of a struggle. I was a bit nervous, yes.

"I would have laughed [if someone told me I was going to win] but it feels great for sure. Nobody expected this, not me, not my team. I'm happy I'm injury free and, oh my God, I made it."

Kvitova is the second woman to win the singles title in Miami after turning 33, following Serena Williams in 2015.

Indeed, only Serena Williams (68), Justine Henin (42), Venus Williams (40), Kim Clijsters (40) and Maria Sharapova (36) have more WTA singles title to their name in the 21st century than the Czech.

Rybakina, meanwhile, will lament the chance of a Sunshine Double going begging.

The 23-year-old is the fourth player to fail to win the Sunshine Double in Miami's final after Serena Williams (1999), Lindsay Davenport (2000) and Sharapova (2006 and 2013).

"I want to congratulate Petra for a great two weeks here in Miami, and good luck for the rest of the year," said Rybakina. "Thank you to my team, we'll keep going."

Petra Kvitova is through to her 41st WTA singles final after defeating Sorana Cirstea 7-5 6-4 in Friday's Miami Open semi-final.

Kvitova, 33, already has 29 singles titles under her belt, including eight at the WTA 1000 level. Despite showing she can still compete with the best – making the final at the 2019 Dubai Championships, the 2020 Qatar Open and the 2022 Cincinnati Open, her last WTA 1000 victory came at the 2018 Madrid Open.

Against Romania's Cirstea – who came into the contest with nine wins from her past 10 matches – Czech veteran Kvitova was put on the back foot early as her serve was broken to go 5-2 down.

But she saved two set points, and used that momentum to ignite a run of seven consecutive games, taking the first set and the early break in the second as a result.

Kvitova did not allow Cirstea to produce a single break point opportunity in the second set, winning 75 per cent (21-of-28) of her total service points to slam the door shut.

With the win, Kvitova joined Chris Evert and Serena Williams as the only women to ever reach the Miami Open final after turning 33 years old, booking her place against the hottest talent on the tour – Elena Rybakina – in the decider.

Rybakina has won her past 13 matches, and is looking to become the fifth woman to ever complete the Sunshine Double after eliminating both world number one Iga Swiatek and world number two Aryna Sabalenka to lift the Indian Wells Open title.

Elena Rybakina is now one win away from completing the Sunshine Double after defeating Jessica Pegula 7-6 (7-3) 6-4 in Thursday's Miami Open semi-final.

Only four women have ever claimed the Sunshine Double – which requires winning both the Indian Wells Open and Miami Open. Steffi Graf did it in both 1994 and 1996, Kim Clijsters did it in 2005, Victoria Azarenka accomplished the feat in 2016 and current world number one Iga Swiatek did it just 12 months ago.

Rybakina sent a message to the tennis world as she knocked out both world number one Iga Swiatek and world number two Aryna Sabalenka to take home the Indian Wells crown, and she has carried that form into Miami.

After prevailing in three-setters against Anna Kalinskaya and Paula Badosa, the Kazakhstan representative has now rattled off consecutive straight sets victories against Elise Mertens, Martina Trevisan and Pegula to extend her winning streak to 13 matches.

Against Pegula, Rybakina served 11 aces to the American's one, and in the process she became the first woman to serve at least 10 aces during five matches in the same tournament since Serena Williams back at Wimbledon in 2016.

By securing the first-set tiebreaker, Rybakina claimed her tour-leading seventh tiebreaker win of the season, with a perfect 7-0 record.

She will meet the winner between Petra Kvitova and Sorana Cirstea in the final after the Czech veteran emerged victorious 6-4 3-6 6-3 in her quarter-final against Russia's Ekaterina Alexandrova.

The neck-and-neck contest saw Kvitova only narrowly edge the total point count 96-91, but she created nine break points to Alexandrova's six.

Kvitova, 33, is now one win away from her 41st WTA singles final, where she would be seeking her 30th WTA title, and her ninth at the WTA 1000 level. It would be her first at this level since the 2018 Madrid Open, following defeats in the finals of the 2019 Dubai Championships, the 2020 Qatar Open and the 2022 Cincinnati Open.

World number 74 Sorana Cirstea produced a major shock in the Miami Open quarter-finals after toppling 2023 Australian Open champion Aryna Sabalenka in straight sets on Wednesday.

The 32-year-old Romanian triumphed 6-4 6-4 over the in-form Belarusian to progress to her first WTA-1000 semi-final for a decade, dating back to the 2013 Canadian Open in Toronto.

World number two Sabalenka came into the contest as the highest remaining seed after Iga Swiatek's withdrawal, having won a tour-leading 20 matches this season.

But Cirstea blew Sabalenka away in one hour and 27 minutes, maintaining her fine run in Miami where she has not dropped a set in five matches.

Sabalenka hit more winners than Cirstea (21-16) but the Romanian was more polished, committing only nine unforced errors compared to the Australian Open winner's 21.

Cirstea broke Sabalenka in the first game of each set and showed resolve when she served out victory from 15-40 down.

"I think I'm a bit speechless," Cirstea said after the match. "I came out knowing that it's going to be a really tough match. Aryna hits so hard, so I knew I had to hold my ground, and I'm very, very happy with my performance today."

Cirstea's list of scalps includes fifth seed Caroline Garcia, former top 20 player Karolina Muchova and now Sabalenka.

The Romanian also reached the quarter-finals at the Indian Wells Open a fortnight ago, losing to Swiatek in the last eight.

Cirstea will need to wait to learn her semi-final opponent with the quarter-final between 15th seed Petra Kvitova and 18th Ekaterina Alexandrova re-scheduled to Thursday after the evening session was cancelled due to persistent rain.

Reigning Wimbledon and Indian Wells Open champion Elena Rybakina extended her winning streak to 11 matches with Monday's 6-4 6-3 victory over Elise Mertens in the Miami Open fourth round.

Rybakina, 23, has been one of the most in-form talents in the sport this year, with her only two losses since the start of the Australian Open coming in three-setters against Aryna Sabalenka and Beatriz Haddad Maia.

The Kazakhstan representative produced 10 aces against Mertens on her way into the quarter-finals, becoming the first player this WTA season to finish with at least 10 aces in three consecutive matches.

She will look to keep her sparkling form alive when she meets Martina Trevisan for a spot in the semi-finals, after the Italian got the better of Latvia's Jelena Ostapenko 6-3 6-3.

Sabalenka showed why she is the top remaining seed after Iga Swiatek's withdrawal, beating 16th seed Barbora Krejcikova 6-3 6-2. Krejcikova was one of two players this season to beat Sabalenka – with Rybakina the other – and by avenging that defeat the Belarusian improved her record in 2023 to 20-2.

America's top hope Jessica Pegula needed only 79 minutes to eliminate Magda Linette 6-1 7-5, winning the first five games of the match to set the tone early, and she will now meet Russia's Anastasia Potapova in the quarters.

Potapova finished with just one ace compared to Qinwen Zheng's nine, but she showed enough guile to overcome the Chinese international's power advantage.

Romania's Sorana Cirstea kept her great run going with a 7-6 (7-3) 6-4 triumph over Marketa Vondrousova, making it eight wins from her past nine matches, and Bianca Andreescu was forced to retire through injury while down a set 7-6 (7-0) 0-2 against Ekaterina Alexandrova.

Aryna Sabalenka needed just 68 minutes to dispatch Marie Bouzkova 6-1 6-2 in Sunday's third round of the Miami Open.

Sabalenka hit 26 winners in the victory and now has 250 at WTA 1000 level for the season, representing one of only two female players with more than 200 in 2023.

The world number two, who is the top seed in the tournament after Iga Swiatek's withdrawal, has now won 19 of her past 21 matches, with her only losses in that span to Elena Rybakina and Barbora Krejcikova.

She will get the chance to avenge that loss to Krejcikova next after the Czech Republic representative knocked out hometown star Madison Keys 7-6 (7-4) 6-3.

Former French Open winner Krejcikova registered her 10th WTA 1000 level win against Keys, becoming only the second player to achieve that this season.

Former Australian Open champion Sofia Kenin fell 6-4 6-4 to Canada's Bianca Andreescu, who continued her strong run after previously knocking out seventh seed Maria Sakkari and 2021 US Open champion Emma Raducanu.

In a serve-dominated match, 2019 US Open champion Andreescu sent down seven aces, maintaining 70 per cent first serve percentage.

Ninth seed and former Olympic gold medallist Belinda Bencic was eliminated 7-6 (10-8) 6-3 by 18th seed Ekaterina Alexandrova, who will take on Andreescu in the next round.

Marketa Vondrousova won her all-Czech matchup against 17th seed Karolina Pliskova, and their compatriot Petra Kvitova enjoyed a 6-4 7-6 (7-3) triumph over recent Monterrey Open champion Donna Vekic.

Romania's Sorana Cirstea made it seven wins from her past eight matches with a 7-5 6-1 result over Karolina Muchova, having knocked off fifth seed Caroline Garcia in the second round.

Varvara Gracheva ensured a strong day for the Russians with a 6-1 6-2 demolition of Magdalena Frech in a battle of two unseeded players.

Top 10 seeds Ons Jabeur, Caroline Garcia and Maria Sakkari were all eliminated in a day of upsets in the Miami Open second round on Friday.

Qualifier Varvara Gracheva earned her first career top-five win by beating 2022 Wimbledon and US Open finalist Jabeur 6-2 6-2 in only 67 minutes.

Fifth seed Caroline Garcia also crashed out, losing 6-2 6-3 to 74th-ranked Sorana Cirstea, having also recently beaten the Frenchwoman at Indian Wells.

Bianca Andreescu came from a set down to beat seventh seed Maria Sakkari 5-7 6-3 6-4 in a match that lasted over three hours.

Andreescu displayed some of the form that saw her lift the 2019 US Open title, fighting back from a set down and proving composed in the big moments.

The Canadian, who is ranked 31st, will take on 2020 Australian Open champion Sofia Kenin in the third round.

Second seed Aryna Sabalenka had few problems against Shelby Rogers, winning 6-4 6-3 in one hour and 17 minutes. Sabalenka will next face 31st seed Marie Bouzkova.

The 2023 Australian Open champion has won 65 main draw matches in WTA-1000 events, which equals Marion Bartoli and Ashleigh Barty at the 30th place since 2009 for the most wins at this level.

Indian Wells winner Elena Rybakina beat Anna Kalinskaya 7-5 4-6 6-3, and Petra Kvitova eased past compatriot Linda Noskova 6-3 6-0.

Ninth seed Belinda Bencic dropped just two games as she cruised past Leylah Fernandez 6-1 6-1, and will face Ekaterina Alexandrova next as the 18th seed needed three to get past Taylor Townsend.

Veronika Kudermetova was eliminated by Marketa Vondrousova 6-4 6-2, who goes up against Karolina Pliskova in round three after she eased past Wang Xinyu in straight sets.

Maria Sakkari prioritised a pedicure after earning a shot at Australian Open champion Aryna Sabalenka in the Indian Wells Open semi-finals.

Thursday was to be a recovery and re-setting day for Greek Sakkari, one of the stars of the Netflix 'Break Point' series, who is through to her third semi-final of the year.

She booked a last-four spot thanks to a stunning fightback from a set and a break down to Petra Kvitova, but Sakkari's efforts this week in California have left her with bleeding toes.

It is hardly surprising, considering she has taken a long route through to the semi-finals, reeling off four consecutive three-set wins.

Sakkari has lost the first set in three of those four matches but found a way to battle back, but she will want to start strongly against a dialled-in Sabalenka.

After coming through 4-6 7-5 6-1 against Kvitova, Sakkari said in an on-court interview: "I need a pedicure because my feet are bleeding so badly."

Asked about that comment later, she said in a press conference: "It's just my nails. It's not ideal, but nothing bad, like I can properly play and run and everything, but it's not nice."

It sounds far from pleasant, yet Sakkari fights on, aware that despite not playing her top-level tennis so far this fortnight, resilience has pulled her through.

"It is strange, but at the same time, I'm just telling myself, look, you're not playing your best tennis and you're still winning and beating amazing players," Sakkari said.

"By just surviving and just finding ways, eventually I'm sure that my game is going to get better. I really want to see how it's gonna be when I will start feeling good with my game.

"But of course I don't want to say that like I was playing s*** and I won. That's not the case. That's also very bad for the opponent."

Considering Kvitova is a two-time Wimbledon champion and a 29-time singles title winner on tour, Sakkari ranked Wednesday's win as one to log alongside her finest victories.

"For me coming back against her, now that she's playing good, now that she has beaten so many good players, it's a bloody good win," Sakkari said. "The fact I found a way was one of the best comebacks of my life."

Sakkari trails 4-3 in the career head-to-head against Sabalenka despite winning their last two encounters, both at the WTA Finals in each of the past two seasons.

They have not faced each other since Sabalenka became a first-time grand slam champion in Melbourne at the start of the year.

Sakkari was runner-up at Indian Wells 12 months ago, losing to Iga Swiatek in the final, and she has designs on beating Sabalenka to earn another crack at the title match.

Asked about the Belarusian, Sakkari said: "She's an amazing player. I knew that she was gonna win a grand slam. It actually came, and I was very happy for her.

"She's very fun to be around. It's going to be very, very tough, because she's feeling the ball really well."

Australian champion Aryna Sabalenka made light work of sixth seed Coco Gauff in a dominant straight-sets win to clinch her spot in the Indian Wells Open semi-finals on Wednesday.

Sabalenka improved her 2023 season record to 16-1 with a 6-4 6-0 win over the 19-year-old American in only 65 minutes.

The Belarusian will face seventh seed Maria Sakkari in the semi-finals after the Greek edged out 15th seed Petra Kvitova in three sets in the evening quarter-final.

Sabalenka will be tough to beat, however, maintaining her strong season form against Gauff who had little answers despite boasting a 3-1 head-to-head record coming into the clash.

The second seed crushed 18 winners compared to Gauff's 12, while she committed 14 fewer unforced errors across the match.

Sabalenka opened up a 2-0 lead in the first set and maintained that buffer to take the opening frame, before a 25-minute second-set bagel underlined her dominance.

"I feel a little bit different on the court this year," Sabalenka said after the match. "I feel like I'm a little bit different player. I wasn't really focusing on the last matches against her. I was focused on myself."

Sakkari came from behind to defeat two-time Wimbledon champion Kvitova 4-6 7-5 6-1 in two hours and 17 minutes.

The Greek, who finished as last year's Indian Wells Open runner-up, was broken twice in the first set and dropped serve again in the opening game of the second frame, before finding a way to flip the match on its head.

Sakkari broke back for 3-3 in the second set, winning 12 of the final 15 games for victory in an impressive turnaround. All four of Sakkari's matches in Indian Wells this fortnight have gone to three sets.

Top seed Iga Swiatek will be hard top stop in her title defence at the Indian Wells Open after a straight-sets thrashing over Emma Raducanu in Tuesday's last 16.

The Polish world number one eased to victory 6-3 6-1 in one hour and 25 minutes over the 2021 US Open champion, who has enjoyed an improved run this week in California.

Swiatek offered few weaknesses in a strong disciplined display, converting four of 10 break points, including three in a one-way second set.

The three-time major winner won 88 per cent on her first serve while she was impressive on return and able to win the longer rallies. Swiatek hit 22-9 winners while Raducanu made 22-14 unforced errors.

Swiatek will take on Romania's Sorana Cirstea in the quarter-finals, after she upset fifth seed Caroline Garcia 6-4 4-6 7-5 in two hours and 24 minutes.

Reigning Wimbledon champion Elena Rybakina also progressed in that part of the draw, setting up a last-eight clash with unseeded Czech Karolina Muchova.

Rybakina won 6-3 6-0 over qualifier Varvara Gracheva in a similarly strong performance, needing only one hour and 21 minutes.  Muchova beat compatriot Marketa Vondrousova 6-4 6-7 (2-7) 6-4 in two hours and 37 minutes.

Third seed Jessica Pegula was the major casualty of the day's play, going down 6-2 3-6 7-6 (13-11) to 16th seed Petra Kvitova in a dramatic two-hour-and-16-minutes clash.

Pegula had opened up a 5-3 third-set lead and squandered a match point on serve, before two-time Wimbledon winner Kvitova squared it up at 5-5. Kvitova, however, was broken immediately to offer Pegula another chance to serve out the match again, which she was unable to take.

The American generated another three match points in the tie-break but could not convert before the Czech eventually prevailed on her own fourth match point, with the deciding set lasting one hour and 12 minutes.

Kvitova will face seventh seed Maria Sakkari in the quarters after she triumphed in a lengthy clash 6-4 5-7 6-3 over Karolina Pliskova, lasting two hours and 43 minutes.

Second seed Aryna Sabalenka also needed three sets to beat Barbora Krejcikova 6-3 2-6 6-4 in two hours and four minutes. Krejcikova had been responsible for Sabalenka's lone loss this season, in a 15-1 year.

Sabalenka, who won this year's Australian Open, will face sixth seed Coco Gauff who defeated Rebecca Peterson 6-3 1-6 6-4. Gauff won the last four games for victory, having trailed 4-2 in the deciding set.

Third seed Jessica Pegula rallied back from a set down for the second straight match to advance into the final 16 with a 3-6 6-4 7-5 victory over 26th seed Anastasia Potapova.

Potapova won the first set in 39 minutes, claiming the only break of the frame in the sixth game, but Pegula responded by breaking immediately in the second.

Despite squaring the match up, the American trailed 3-1 in the third set, only to fight back again and triumph in two hours and 17 minutes.

Pegula will face 15th seed Petra Kvitova after she won a seesawing three-set contest over 24th seed Jelena Ostapenko, 0-6 6-0 6-4.

Ostapenko won the first six games, before Kvitova won the next 10, only for the Latvian to hit back and claim the next four, squaring up the deciding set at 4-4. But two-time Wimbledon champion Kvitova held her nerve and won the final two games for victory.

World number two Aryna Sabalenka progressed to the final 16 via walkover after her third-round opponent Lesia Tsurenko withdrew.

The 2023 Australian Open champion will take on 2021 French Open winner Barbora Krejcikova after she toppled Wang Xin 6-2 6-7 (1-7) 6-2.

Seventh seed Maria Sakkari secured victory in a two-and-a-half-hour third-round clash with Anhelina Kalinina, winning 3-6 6-2 6-4.

Two-time major runner-up Karolina Pliskova won 6-1 7-5 over Veronika Kudermetova, progressing into the last eight to face Sakkari.

Sixth seed Coco Gauff, who turns 19 on Monday, eased past 54th-ranked fellow teenager Linda Noskova 6-4 6-3 in one hour and 19 minutes.

Sweden's Rebecca Peterson continued her resurgent form with a 3-6 6-3 6-1 win over Jil Teichman, setting up a clash with Gauff.

Aryna Sabalenka showed exactly why she is ranked second in the world as she dominated her opening match of the Indian Wells Open on Friday against Evgeniya Rodina.

Belarus' Sabalenka needed just 66 minutes to defeat the Russian 6-2 6-0, taking advantage of her first-round bye to book her spot in the third round against Ukraine's Lesia Tsurenko.

Tsurenko had to come from behind against the in-form Donna Vekic, fresh off her Monterrey Open title last week, but that big effort may have had the Croatian with heavy legs as she ran out of steam 2-6 6-2 6-2.

It was a strong day for the Ukranians as 27th seed Anhelina Kalinina beat the Czech Republic's Linda Fruhvirtova 4-6 6-4 7-5, and she will next face Greece's Maria Sakkari.

Sakkari, the seventh seed, had to deal with adversity after a poor first set against Shelby Rogers, coming back to win 2-6 6-4 6-0.

Olympic gold medallist Belinda Bencic lost her Swiss showdown against Jil Teichmann 3-6 6-3 6-3, while Veronika Kudermetova got the better of her Russian compatriot Anna Blinkova 6-3 6-4.

The second-highest ranked American in the field, Coco Gauff, had no issues dispatching Spain's Cristina Bucsa 6-2 6-4. But it was tougher work for America's top hope Jessica Pegula as she was pushed all the way by recent Merida Open champion Camila Giorgi, before prevailing 3-6 6-1 6-2.

Liudmila Samsonova progressed after a marathon battle at the Dubai Tennis Championships, while Petra Kvitova breezed through as the seeds escaped unscathed on Sunday.

Two-time Wimbledon champion Kvitova, the 12th favourite in the United Arab Emirates, eased past Italy's Martina Trevisan 6-2 6-1 to make a dominant start.

World number 15 Samsonova was made to work to beat Paula Badosa, winning 6-7 (3-7) 7-6 (7-5) 6-4 to tee up a clash with Qinwen Zheng, who overcame compatriot Zhang Shuai in straight sets.

Samsonova's triumph took three hours and 22 minutes, the longest match of the WTA Tour season thus far, in a thrilling first-round encounter between two top-20 players.

"Playing against Paula is always tough," 14th seed Samsonova said in her on-court interview. "She's doing unbelievable, so I'm really proud that I stayed on the court until the end.

"I think I'm growing match after match, day by day. I know it's a long journey, and I hope to continue like that."

Barbora Krejcikova, the 2021 French Open champion, cruised into the last 32 with a comfortable 6-4 6-2 victory over Irina-Camelia Begu as she aims to go one better than her runners-up finish two years ago in Dubai.

Another routine victory saw American Madison Keys ease past Jasmine Paolini 6-1 6-1, but there was no such luck for 2020 Australian Open champion Sofia Kenin.

She was dispatched 6-1 6-1 by world number 26 Marie Bouzkova, while Amanda Anisimova claimed a 6-3 6-2 win over veteran two-time grand slam finalist Vera Zvonareva.

Viktoriya Tomova had too much for Kaia Kanepi in a 6-3 6-1 success, with her reward a second-round clash against third seed Jessica Pegula.

World number four Pegula lost to the in-form Iga Swiatek in the Qatar Ladies Open final on Saturday, and Leylah Fernandez will face the Pole next after beating Julia Grabher 6-4 6-2.
