Belinda Bencic survived a scare as she advanced to the Charleston Open second round with a 4-6 7-6 (7-5) 6-3 win over Wang Xiyu.

The Olympic gold medallist was a semi-finalist in Miami last time out, while she has also reached the quarter-finals in Sydney and St Petersburg this year.

However, the 10th seed was in danger of falling at the first hurdle at 5-2 down in the second set against world number 149 Wang.

Bencic rallied to force a tie-break and, subsequently, a deciding set, which she controlled to set up a second-round clash with 16-year-old Linda Fruhvirtova.

Magda Linette also fought back from the brink of defeat; the world number 64 saving a match point before prevailing against Maria Voleynets 4-6 6-3 7-6 (7-4).

Although, there was no joy for former champion Sloane Stephens, who was beaten in three sets by Zheng Qinwen.

Stephens – winner here in 2016 – recovered from losing the opening set 6-3 to take the second 6-4. But there was no denying the Chinese teenager, who dropped just nine points as she raced through the decider 6-0 to claim the first top-50 win of her career.

The likes of Jessica Pegula and Madison Keys were due to feature in the evening session, which was postponed due to severe inclement weather including the possible threat of a tornado.

In Bogota, top seed and home favourite Camila Osorio advanced to the last 16, but only after opponent Ylena In-Albon was forced to retire at 2-2 in the deciding set.

Fourth seed Hanna Udvardy and eighth seed Harriet Dart were beaten in straight sets by Dayana Yastremska and Elina Avanesyan respectively.

Alize Cornet was the highest seed in action on the first day of the Charleston Open, and showed her class, beating Alycia Parks 6-0 7-5.

Cornet, the 12 seed, was nearly perfect in the first set, winning 86 per cent of her service points (12-14) and 80 per cent of her return points (12-15).

15 seed Amanda Anisimova also made it through, and with an identical scoreline, defeating American compatriot Sachia Vickery 6-0 7-5.

China's Shuai Zhang is the 16 seed, and she also only needed two sets to see off unseeded opponent Francesca Di Lorenzo 6-2 6-4.

Hungary's Anna Bondar earned a second-round matchup against world number three Paula Badosa after defeating the Netherlands' Arianne Hartono 6-1 6-4.

Italian Jasmine Paolini will meet six seed and world number 13 Jessica Pegula in the second round after beating Romania's Gabriela Lee 6-2 6-3.

Meanwhile, in Bogota at the Copa Colsanitas, Brazilian qualifier Laura Pigossi defeated five seed Harmony Tan 6-4 6-3.

Top seed and world number 33 Camila Osorio will kick off her tournament on Tuesday against Ylena In-Albon.

Iga Swiatek has revealed she was "crying for 40 minutes" when she discovered Ash Barty had retired and the Polish sensation has felt "a range of emotions" after becoming world number one.

Barty sensationally called time on her career at the age of 25 last month.

The Australian quit while she was at the top of the rankings and on the back of winning her home grand slam for the first time at Melbourne Park in January.

Swiatek on Monday became Poland's first world number one and the 20-year-old could be hard to dislodge, as she is on a 17-match winning run.

The 2020 French Open champion became the youngest woman to win the Sunshine Double on Saturday when she beat Naomi Osaka in the Miami Open final after being crowned champion at Indian Wells.

Swiatek was in tears after finding out that Barty had ended her playing days and it soon sunk in that she would officially become the best player in the world.

She told BBC Sport: "I was crying for 40 minutes. Mainly, it was because of Ash's retirement. I didn't know it was going to happen and it really surprised me.

"I always had this vision that we would all play until we are 35 or something, until our bodies are so tired that we can't anymore.

"I needed time to actually understand what she must have thought. Her decision was really brave and I felt a lot of emotions because of that."

She added: "I also felt emotional because of my own position.

"I realised after two hours of being really emotional that 'hey, you don't know what is going to happen yet and you still have to win some matches'.

"So I told myself 'let's wait with the emotions and with being excited because I have work to do'."

Swiatek won the Qatar Open before claiming another two prestigious titles in the United States and the Warsaw native says the manner in which she has dominated has taken her by surprise.

"Emotionally it has been really intense and I have felt a range of emotions – from being proud and having satisfaction, to confusion and surprise," she said.

"These last weeks showed me I can trust in myself a little bit more and trust my skills and my tennis. Before I didn't really know it was possible for me to have a streak like that. So it also kind of surprised me.

"After Doha and after Indian Wells I didn't have time to digest what I've achieved. Right now I am going to take some time to analyse what happened from a 'work' point of view."

Iga Swiatek scored a sensational win against Naomi Osaka in the Miami Open final and predicted it would mark "the start of a great rivalry".

A 6-4 6-0 victory for Swiatek means the new WTA number one has won three consecutive WTA 1000 titles, becoming the first player to do so at the beginning of a season.

Saturday's success sealed the 'sunshine double' as the 20-year-old captured the Indian Wells and Miami titles back to back, becoming the youngest player to achieve that feat, and only the fourth in history, after Steffi Graf, who did it twice, Kim Clijsters and Victoria Azarenka.

Addressing Osaka, Swiatek said: "I wanted to say I'm pretty glad we could play this match, and I think it's the start of a great rivalry.

"You're really an inspiration and this sport is better with you, so keep going."

Osaka is battling her way back into the sport after documenting her struggles with mental health and depression, and her ranking stood at 77 before this tournament.

She was reduced to tears in Indian Wells after being heckled by a spectator, and the Japanese star, a former WTA number one, referenced that incident in a post-match speech after losing to Swiatek.

Thanking her support team, Osaka said they were "the ones who keep pushing me forward after the things that happened two weeks ago – they're the rock that stays by my side".

Although Swiatek beat her resoundingly in the final, these two appear to be close allies, with a meal they enjoyed together in Australia in January 2020 having sparked a friendship.

"I want to congratulate Iga," said Osaka. "I was just thinking yesterday about when I had that dinner with you in Australia, and watching your journey is really incredible, and I hope you continue having fun. Apparently we're tied 1-1 now."

Osaka, who beat Swiatek in Toronto three years ago in their only past meeting, said her conqueror was "an incredible, amazing person", and assured her own supporters she had been having "a lot of fun".

"I hope I can keep working hard and get more opportunities to be in a situation like this again," Osaka added. "Just to be in the final means a lot to me."

That is both pertinent and refreshing given Osaka's future in tennis has appeared in doubt during the past year.

Swiatek, meanwhile, goes from strength to strength. From her French Open final triumph in October 2020 to this latest win, she has won each of the six finals she has contested. Across the last four, Swiatek has won four 6-0 'bagel' sets.

Doing the Indian Wells and Miami double, after previously taking the Doha title this year, shows Swiatek to be a worthy number one.

"I didn't think that was possible," she told Amazon Prime, assessing her back-to-back wins in America. "I'm trying to see what my limits are, and when I was coming from Indian Wells, I said to my coach, 'Did you ever have a situation like that where a player plays the final at Indian Wells and has to play the next match in three days?'. He said that I shouldn't worry and we can do it."

Swiatek's winning streak stands at 17 matches, her record for the season is 26-3, and she has won 20 consecutive sets. Her new number one status will be confirmed on Monday, when the newly retired Ash Barty is taken off the WTA list, and Swiatek hopes to stay there.

"We're going to see. The end of the season is still a long way," she said. "I hope I'm going to keep doing well with the pressure."

Iga Swiatek sealed the 'sunshine double' with a trouncing of Naomi Osaka as the new world number one added the Miami Open title to her Indian Wells triumph.

Twenty-year-old Swiatek will succeed the retired Ash Barty on top of the WTA rankings on Monday, and she has reached the top spot for the first time in staggering style.

A 6-4 6-0 victory against former number one Osaka in Saturday's final made Swiatek the first player to win the first three WTA 1000 events in a season.

Those are the highest value tournaments on the tour outside the grand slams, and Swiatek has chopped down the fields in Doha, Indian Wells and now Miami in staggering fashion.

Her winning streak stands at 17 matches, her record for the season is 26-3, and she has won 20 consecutive sets.

Swiatek set the tone for the match when she broke for a 3-2 lead in the opening set, whipping an exquisite backhand winner across court to seize the initiative.

She had a look-in next time around too, with Osaka doing well to fend off a break point and keep the Pole within touching distance.

The first set was secured when Osaka hoisted an aggressive forehand service return long, and that ramped up the pressure at the beginning of the second

In a flash, Swiatek earned herself three breakpoints, and although Osaka saved the first with a drive volley, the Japanese player sent a forehand into the net on the next point

Swiatek was displaying some startling shot-making, and a cross-court forehand winner in the third game was a thing of beauty, helping her establish a double break.

Osaka is battling her way back into the sport after documenting her struggles with mental health and depression, and her ranking stood at 77 before this tournament.

By reaching the final she proved her talent remains formidable, but Swiatek at present is on another level to her tour rivals, and a clinical sweep of the second set was complete when Osaka hooked a forehand wide.

Only three players had previously secured this back-to-back double in Miami and Indian Wells: Steffi Graf in 1994 and 1996, Kim Clijsters in 2005 and Victoria Azarenka in 2016. Swiatek is the youngest to achieve the feat.

Naomi Osaka is through to her first tournament final since her 2021 Australian Open win, getting past Belinda Bencic 6-4 3-6 6-4 at the Miami Open on Thursday.

The reigning Olympic champion looked strong early, breaking twice to go up 4-1 as she took advantage of Osaka's second serve, winning nine of the 11 second serves she saw in the opening set.

As Osaka's success on second serve cleaned up in the second set, Bencic's avenue to victory vanished, unable to save either of the two break points she faced in the second set.

Osaka's first serve percentage shot up to 70 in the deciding set, winning 87 per cent of points on first serve (20-23) to shut the door. Despite Bencic breaking back once after going down a double-break, she was unable to stop her Japanese opponent from serving it out.

Speaking on court after her win, the Florida native was emotional, shedding some tears as she thanked the fans in attendance.

"I just wanted to say thank you everyone, the atmosphere was really good," she said.

"Damn, I'm always crying. I just wanted to say thank you, this tournament really means a lot to me and it's my first time in the finals here."

World number-one-in-waiting Iga Swiatek twice came back from a break down in the second set to overcome the challenge of American Jessica Pegula 6-2 7-5.

The straight sets win for the 20-year-old Polish star means she has now not dropped a set in eight straight matches dating back to the fourth round at the Indian Wells Open where she beat Angelique Kerber two sets to one. 

Against Pegula, Swiatek was simply too strong in the opening set, breaking twice in four tries when Pegula's second serve was vulnerable, with the American only winning 27 per cent of her second serve points (4-15) in the opening frame.

The second set was far more competitive, but Swiatek remained just slightly better both on serve and in the return game in a set where four consecutive games resulted in breaks in a seesawing contest.

Pegula refused to let the top seed serve it out comfortably, saving two match points to extend the second set at 5-5. It was just delaying the inevitable as Swiatek broke back instantly and held her nerve, and serve, to avoid a tie-break.

 

Elina Svitolina is taking a much-needed break from tennis due to physical and mental stress brought on by injuries and Russia's invasion of her native Ukraine. 

The world number 20 revealed she had been struggling with a back injury that affected her preparations for tournaments, falling at the first hurdle in each of her past two events.

Svitolina, the 2018 WTA Finals champion, reached the last eight at the Monterrey Open, where she refused to play Anastasia Potapova unless the Russian was classed as a neutral athlete at the start of the month, but she lost in her first match at both Indian Wells and the Miami Open.

Svitolina's sabbatical means she will be absent from Ukraine's Fed Cup clash with the United States next month, and it remains to be seen if she will return in time for the French Open at the end of May.

The 27-year-old posted on Twitter: "It's been an extremely difficult couple of months for me not only mentally, but physically. 

"For quite a long time, I've been struggling with my back; the pain didn't let me prepare for the tournaments at my best.

"Meanwhile, observing with unbearable pain in my heart what is happening in my homeland of Ukraine and with how much bravery and courage our Ukrainian people are defending our country, this gave me a huge push to continue and fight on court.

"Now, my body can't handle it anymore and I need to rest, therefore I'm sad to announce that I will be missing the Fed Cup and a few of my favourite tournaments in Europe. But, I'm sure I will see you around soon, thank you for all your support in this challenging period."

Will Smith has apologised to Serena and Venus Williams and their family, as well as Chris Rock, after his on-stage slap aimed at the comedian marred an Academy Award win.

The Williams sisters were at the Oscars in Los Angeles on Sunday to see Smith win Best Actor for his portrayal of their father Richard in the biopic King Richard.

However, before Smith took to the stage to collect his award, he was involved in the major flashpoint of the night and one of the most remarkable incidents in Academy Awards history.

Smith stormed the stage when Rock, while presenting Best Documentary Feature, made a joke about his wife Jada Pinkett Smith.

Rock appeared to make a comment on Pinkett Smith's hair, which prompted Smith – after originally smiling at the joke – to take to the stage and strike the comedian before telling him to "keep my wife's name out your f***ing mouth".

Smith returned to his seat and was allowed to remain in attendance for the rest of the ceremony, giving a lengthy and emotional acceptance speech in which he apologised to The Academy.

Almost 24 hours past before Smith took to his Instagram page to address the issue again, explaining he took offence to a remark apparently related to his wife's alopecia but also again apologising – including to the Williams family.

"Violence in all of its forms is poisonous and destructive," he wrote. "My behaviour at last night's Academy Awards was unacceptable and inexcusable.

"Jokes at my expense are a part of the job, but a joke about Jada's medical condition was too much for me to bear and I reacted emotionally.

"I would like to publicly apologise to you, Chris. I was out of line and I was wrong. I am embarrassed and my actions were not indicative of the man I want to be. There is no place for violence in a world of love and kindness.  

"I would also like to apologise to The Academy, the producers of the show, all the attendees and everyone watching around the world.

"I would like to apologise to the Williams family and my King Richard family. I deeply regret that my behaviour has stained what has been an otherwise gorgeous journey for all of us.

"I am a work in progress."

In her own post on Sunday, Serena Williams had seemingly sought only to address Smith's success at the Oscars.

"This night has been surreal," she wrote. "To spend it sitting next to my sisters meant more than anything.

"I am so grateful to The Academy for making this an unforgettable night, and to Will Smith for bringing this story to the big screen and honouring my family. This will always be a night to remember."

World number two Iga Swiatek showed why she is next in line to occupy the top ranking as she comfortably handled the challenge of 14 seed Cori Gauff 6-3 6-1 to earn a spot in the quarter-finals at the Miami Open.

Swiatek, 20, will become the first Polish-born man or woman to earn the number one singles ranking when it is next updated on April 4, after Ash Barty's retirement, and she never gave Gauff a chance.

She won all eight of her service games in the match, and broke Gauff's serve four times in eight chances to rattle off five consecutive games to close the match.

After a walkover in her last fixture, Naomi Osaka was strong on her way to a 6-3 6-4 win against Alison Riske.

Both women produced break points throughout the match, but while Osaka saved seven out of eight, coming back to double-break after her slip-up in the second set, Riske could only save nine of 12.

In a clash between top-10 seeds, Danielle Collins was terrific in her 6-2 6-4 win against Ons Jabeur.

The match was decided by each woman's success on their second serve, as Jabeur had the better first serve, but could only win 31 per cent of her second serves (8-26), while Collins was an even 73 per cent on both her first and second attempts.

Daria Saville continued her march back up the rankings with a 5-7 6-4 7-5 win against Lucia Bronzetti, making it nine wins from her past 10 matches for the Australian ranked 249 in the world after recently returning from a long-term achilles injury.

Saville will play Switzerland's Belinda Bencic after she breezed past Belarus' Aliaksandra Sasnovich 6-2 6-3, while Petra Kvitova got the better of higher-ranked Veronika Kudermetova 7-6 (7-5) 6-4.

American Jessica Pegula was nearly flawless on her way to a 6-0 first set before Ukrainian Anhelina Kalinina retired due to injury, while world number six Paula Badosa beat wildcard Linda Fruhvirtova 6-2 6-3.

 

Iga Swiatek was in a ruthless mood as she coasted into the last 16 of the Miami Open, setting up an intriguing clash with Coco Gauff.

Swiatek was in action for the first time since ensuring she will be top of the pile after the next WTA rankings update, and she certainly showed world-number-one form against Madison Brengle in a 6-0 6-3 victory.

The 20-year-old Pole needed just 25 minutes to win the opening set, during which she hit 12 winners to Brengle's one.

Brengle gave a better account of herself in the second set but Swiatek still had far too much for her, with the latter remaining on course to become only the fourth woman to win the so-called 'Sunshine Double' of Indian Wells and the Miami Open.

But certain expectations – particularly those relating to her ranking – are not what Swiatek wants to think about at the moment, especially while she is so content out on the court.

She said: "I know the ranking can be pressure, but on the other hand when I was climbing up and I entered top 10 and top five, I felt the same feeling, and right now I don't want to repeat that. So I just focus on my game.

"I don't know what's going to happen after the tournament and the adrenaline will go down and I have more time to stress about that a little bit more, but for now I feel great. It's not like it's bothering me, it's more motivating me. So it's great."

Gauff, competing in her local tournament, awaits after showing admirable spirit to beat Zhang Shuai 7-6 (7-1) 7-5.

The 18-year-old had to save two set points in the opener before rallying back and producing a devastating display in the tiebreaker.

She then came back from 4-2 down in the second, winning five of the final six games to seal a hard-fought victory.

Another teenager hoping to leave a lasting impression is 16-year-old Linda Fruhvirtova, who became the youngest player to reach the fourth round in Miami since Maria Sharapova and Tatiana Golovin in 2004 – both were also 16.

Fruhvirtova was 6-2 3-0 up over Victoria Azarenka before the three-time Miami Open winner retired, giving the youngster her first top-20 scalp.

Jessica Pegula, Petra Kvitova and Paula Badosa were among the others to secure their progression on Sunday.

Nick Kyrgios has defended Emma Raducanu amid a wave of recent criticism following the US Open champion's early exit from the Miami Open.

Raducanu was beaten by Katerina Siniakova in her first match in Miami this week after being given a bye into the second round.

She has won only four WTA Tour matches since sensationally becoming the first qualifier – male or female – to win a major in the Open Era at Flushing Meadows in September.

The 19-year-old has been in demand off the court, having last week announced she will be a brand ambassador for Porsche, but her business activities have attracted criticism.
 
Speaking after Raducanu's defeat to Siniakova, former world number five Daniela Hantuchova claimed the Briton has lost the locker room respect she had previously built up.

Kim Clijsters took aim at those who act as though they have "made it", meanwhile, though the four-time major winner did not mention Raducanu by name when making those comments.

Raducanu defended herself from the "unfair" accusations and Kyrgios has now questioned why former players have felt the need to take aim at the youngster.

"What’s with old retired players giving their opinion on our stars now?" he posted on Twitter, referencing a video uploaded by Andy Roddick on how players can curtail their anger.

"I love A-rod and I agree we all need to chill with the rackets and all that, but geezus.

"I read an article about a past female player talking about Radacanu, no offence, but she is a far, far bigger name already."

Robert Lewandowski joined skiing greats Lindsey Vonn and Mikaela Shiffrin in saluting Iga Swiatek for earning the number one ranking in women's tennis for the first time.

At the age of 20, Swiatek guaranteed she will top the WTA list after the Miami Open by beating Viktorija Golubic 6-2 6-0 in her opening match at the event.

Swiatek will replace Ash Barty, whose shock retirement will see the Australian drop off the ranking ladder entirely when it is next published on April 4.

Since a shock French Open victory in October 2020, when the unseeded Swiatek stormed through the draw without dropping a set, the Polish youngster has continued to make a major impact.

She reached at least the fourth round of all the grand slams last year and was a semi-finalist at the 2022 Australian Open, before victory at WTA 1000 events in Doha and Indian Wells propelled her to number two in the rankings.

Now she will climb a step higher, and that news has proven popular with Swiatek's supporters, who include a number of illustrious names.

Fellow Polish sporting star Lewandowski, who is rewriting goalscoring records in Germany with Bayern Munich, sent his compatriot a message on Instagram that read simply: "Congratulations Iga. Well done."

Swiatek is a huge admirer of Americans Vonn and Shiffrin, who have both landed World Championship and Olympic gold medals on the slopes, and the respect is mutual.

Vonn told Swiatek her achievement was "So deserved!!", and Shiffrin posted: "Congrats Iga!!"

Former WTA number one Kim Clijsters, who was also 20 when she first hit the top spot in 2003, felt it was a natural next step for Swiatek to move up a rung and become the 28th top-ranked player in the tour's history. Swiatek will also be the first Pole to sit at the summit.

Clijsters said: "To see Iga grow as a tennis player, it has been so beautiful for me. There's a certain type of focus that is on tennis, and tennis only. There's a drive there that I admire very much – a drive that I recognise."

Belgian Clijsters, quoted on the WTA website, added: "She's had great results in the past, but she still wants to improve. We've seen others that kind of take a step back and say, 'Oh, I've won a slam now, I've made it. There's sponsors coming in and I get treated like a princess wherever I go'.

"Just because you’re the number one player and have won slams, doesn't mean you should treat other people differently. I feel like Ash Barty did that amazingly, and I think Iga has that focus, too."

Emma Raducanu has hit back "unfair" criticism over her mounting sponsorship deals following her early exit from the Miami Open.

The US Open champion was beaten by Katerina Siniakova in her first match in Miami this week after being given a bye into the second round.

Raducanu has only won four WTA Tour matches since she was sensationally crowned champion at Flushing Meadows as a qualifier in New York last September.

The 19-year-old has been in demand off the court and last week revealed she will be a brand ambassador for Porsche.

Briton Raducanu insists she is still driving high standards in training as she strives to build on her maiden grand slam triumph.

"Maybe you just see, on the news or on social media, me signing this or that deal and I feel like it’s quite misleading because I’m doing five, six hours a day [in training], I’m at the club for 12 hours a day," the 19-year-old told reporters.

"But I throw out one post in the car on the way to practice and all of a sudden it’s 'I don't focus on tennis'. I think that it is unfair, but it's something I have learned to deal with and become a bit more insensitive to the outside noise.

"At the end of the day, I feel like my days [with sponsors] are pretty limited. I'm not doing crazy days. I'm doing three, four days every quarter, so it's really not that much."

New world number one Iga Swiatek says taking the top rank is a "dream come true" and something she never strongly believed could happen.

Swiatek made history as the first Polish tennis player to reach the top ranking, taking over the mantle following Ashleigh Barty's shock decision to retire from the sport in midweek. She will officially become number one when the WTA rankings are updated on April 4.

The 20-year-old Pole, who won the 2020 French Open and made this year's Australian Open semi-finals, made the ascent to the summit after beating Viktorija Golubic 6-2 6-0 at the Miami Open on Friday.

"It's a dream come true, for sure," Swiatek told reporters. "It's that kind of thing that I wanted to happen someday, but I didn't really know that it's going to be possible for me.

"I never really imagined that moment, because truth to be told, I was working day by day and I was playing tennis well, but I never had that like that strong belief that it can actually happen, so it's even more surreal for me."

Swiatek has claimed WTA 1000 titles at Indian Wells and Doha this year, with her victory over Golubic extending her winning run to 12 matches.

She is the 28th woman to reach the summit in the WTA rankings, becoming the youngest player at the top since Caroline Wozniacki in 2010.

"I think it's going to be a bit different and maybe the hype is going to be a bit bigger, but I'm ready for that," she said.

"Honestly, it's like part of the job, so I always knew if I'm going to succeed, it's going to be there. I really appreciate people being really enthusiastic and really pumped up because I think sometimes I'm even playing for them."

Barty was quick to congratulate Swiatek on claiming the number one ranking, saying there is "no better person" than the Pole.

"There is no better person," Barty said in a message. "The way that she's brought this fresh, fearless energy onto the court has been incredible.

"I hope she can take it and still be her, do it her own way, and really chase what she's after in her career and her dreams."

Former French Open champion Iga Swiatek has risen to world number one in the wake of Ashleigh Barty's retirement with a 6-2 6-0 win over Viktorija Golubic at the WTA Miami Open on Friday, sealing her ascent.

Swiatek, who won recent WTA 1000 events this year at Indian Wells and Doha, cruised to victory in one hour and 14 minutes over the Swiss.

The 20-year-old Pole, who won the French Open in 2020 and reached this year's Australian Open semi-finals, will officially become the top-ranked player when the rankings are updated on Monday April 4.

Barty's name will be removed from the rankings at her request having announced her shock retirement earlier this week at the age of 25, despite winning this year's Australian Open and last year's Wimbledon titles.

Swiatek is the 28th woman to reach the summit in the WTA rankings, becoming the youngest player at the top since Caroline Wozniacki in 2010. She will become Poland's first-ever number one in tennis history.

The Pole extended her winning streak to 12 matches against Golubic, taking her to a tour-high 21 wins this year, in a match where she saved eight of nine break points and took six of the nine she generated.

Swiatek's main immediate competition for the top rank was fifth seed Paula Badosa who got past Marie Bouzkova 7-5 7-5 in two hours and three minutes.

Badosa, who got the edge by grinding out games under pressure, will face Yulia Putintseva in the third round after she won 6-3 4-6 7-5 over Lesia Tsurenko.

Fourth seed Maria Sakkari was bundled out of contention following a shock 4-6 6-1 6-2 loss to Brazilian Beatriz Haddad Maia.

Two-time major winner Petra Kvitova needed three sets to get past Clara Burel, winning 6-1 3-6 6-3 in one hour and 45 minutes.

Jessica Pegula beat Sloane Stephens 6-1 6-4, Cori Gauff got past Qiang Wang 7-5 6-4 and 20th seed Elise Mertens went down 7-5 2-6 6-1 to Linda Fruhvirtova.
