World number one Iga Swiatek cruised into the last 16 of the Madrid Open with a straight-sets victory over Bernarda Pera on Sunday.

The three-time grand slam winner conceded the first break of the match three games in, but she responded brilliantly to that setback to wrap up a 6-3 6-2 win within 76 minutes.

Swiatek did not face a second break point in the match as she rediscovered her composure, continuing her French Open preparations as a barrage of big winners proved too much for Pera.

Speaking on court after her win, Swiatek said: "I wouldn't say it was easy. Every match is tricky here. 

"I'm happy that I'm getting into my rhythm. Playing against a lefty is never easy, but I'm pretty happy with that. I was disciplined and focused."

It was a day of few shocks in the Spanish capital, as third seed Jessica Pegula saw off a spirited challenge from Marie Bouzkova to emerge with a 6-4 7-6 (7-2) win.

Pegula will face Italy's Martina Trevisan for a quarter-final spot after she claimed a straight-sets win over another American player in Alycia Parks.

Meanwhile, Russian duo Veronika Kudermetova and Daria Kasatkina will meet in the next round after victories against Anastasia Potapova and Lesia Tsurenko respectively. 

Elena Rybakina made a second-round exit from the Madrid Open as a difficult start to the clay campaign continued for the Australian Open runner-up and Indian Wells champion.

After abandoning a last-16 clash with Beatriz Haddad Maia last week in Stuttgart due to a back injury, this time Rybakina lasted the distance against Anna Kalinskaya but suffered a 7-5 4-6 6-2 defeat. She had benefitted from a first-round bye but was found wanting on Friday.

World number 60 Kalinskaya got the better of the seventh-ranked Rybakina in two hours and 13 minutes, avenging a defeat at the same stage in Miami last month to her fellow Moscow-born player.

Iga Swiatek made no such mistake in her opening match, after also receiving a first-round bye, with the world number one posting a 6-3 6-2 win over Austria's Julia Grabher.

Swiatek led by an early break in the second set but was broken back; however, she was soon back in the ascendancy and made sure of a place in the last-32 stage of a tournament she elected to miss last year due to a minor injury.

Third seed Jessica Pegula was tested by Poland's Magdalena Frech, but the American came through 7-6 (7-5) 6-3 in an hour and 41 minutes. Pegula was runner-up to Ons Jabeur in last year's final.

Pegula's fellow US player, Alycia Parks, continued to catch the eye as the 22-year-old ousted 15th seed Victoria Azarenka, defeating the former world number one 6-2 7-6 (7-5).

Parks, who has rocketed from 150th in the rankings last November to 40th place on that list, now holds a 4-1 career winning record against opponents ranked inside the WTA's top 20.

Former French Open champion Barbora Krejcikova, seeded 11th, was tested by Danka Kovinic before powering through a deciding set to win 6-3 4-6 6-0 against the Montenegrin.

Eugenie Bouchard, meanwhile, was no match for Martina Trevisan, with the Italian running out a 6-2 7-5 winner from a clash with Canada's former Wimbledon runner-up.

Anastasia Potapova, Ekaterina Alexandrova, Daria Kasatkina, Veronika Kudermetova and Bernarda Pera were among other seeded winners as the last-32 line-up took shape, but 25th seed Jil Teichmann was beaten, going down 3-6 6-2 6-4 to Lesia Tsurenko.

Iga Swiatek considers it a sad state of affairs to see women's tennis lagging so far behind the men's game when it comes to regular tour prize money.

The WTA Tour's top-ranked player earned $120,150 for winning the title at the Stuttgart Open last week, plus a Porsche sports car, when she beat Australian Open champion Aryna Sabalenka in the final.

Yet for taking the title at the Barcelona Open in the same week, a cheque of €477,795 ($527,000) went to Carlos Alcaraz.

Those tournaments are considered comparable in terms of status and the quality of their fields, yet the difference between the money on offer was striking.

It offered a reminder of the gap between the elite men and women at regular tournaments, despite grand slam events offering equal rewards.

Swiatek and Alcaraz both compete this week at the Madrid Open, where prize money for men and women is equal, the champion of each event collecting €1,105,265 ($1.2m).

Asked about last week's situation, Swiatek said: "Well, it's kind of obvious what my opinion is, because tennis is one of the sports where we speak about equality. I think it's better than most sports anyway.

"But still, there is a lot we can work on in terms of getting equal prize money on some WTA tournaments compared to ATP on the same level.

"Grand slams are already even, as we know. That's nice, but for sure it would be good if WTA would focus on that, but I don't really want to get into that, because it's a lot of business and sometimes politics.

"I don't think I have a lot of influence. I just can say that it would be nice for our sport if it was equal, especially because we kind of do the same work."

The 21-year-old Polish player defended the women's game as she said: "I also get people who are saying that men's tennis is nicer to watch and guys can do more because they are physically and biologically stronger.

"I think there were a lot of people, for example a couple of years ago, who were saying that WTA is not consistent and that's a shame and it should be better, but right now basically I think we are even more consistent than the guys with our game.

"Watching women's tennis gives the same emotions, and sometimes even more emotions, because we are women and we are a little bit more emotional. But, yeah, I think it would be nice if WTA could make it even."

Iga Swiatek is delighted by the consistency levels she is demonstrating after completing a successful defence of her Porsche Tennis Grand Prix title on Sunday.

The world number one overcame Australian Open champion Aryna Sabalenka 6-3 6-4 to become the first back-to-back winner of the Stuttgart crown since Angelique Kerber (2015 and 2016).

Swiatek, who was appearing in her first tournament after a rib injury, claimed her second silverware of the season, in which she also completed a successful title defence in Doha.

The Pole has plenty of ranking points to defend this term having won eight titles during a dominant 2022 campaign.

Swiatek was also a finalist in Dubai and, despite a fourth-round exit at the Australian Open, she is pleasantly surprised to have started 2023 in a similar vein of form.

"Honestly, the beginning of the season was so tough that I'm happy to be in that place now," Swiatek said during her post-match press conference.

"I just hope I'm going to continue having that good mindset without looking at all this stuff [defending points]. I was able to do that here. I really like playing on clay, so I just hope I'm going focus on just playing.

"I'm just pretty proud of my consistency, because when I was consistent on another level, it was nice, but this level, it's even over my expectations.

"Last year was really, really tough, and I felt like this season may be tough because of what people are saying and expectations from the outside. Also, I knew how it is to win these tournaments in a row. 

"Now, I feel like I just can use my experience a little bit more. I'm just happy that I'm world number one for more than a year, and it's an exciting time."

Iga Swiatek scooped her 13th career title with a statement victory against Aryna Sabalenka in Sunday's Stuttgart Open final.

The world number one has seen her dominance take a dip this season, with Sabalenka and Elena Rybakina emerging as serious candidates to displace her at the top of the women's game.

However, Swiatek is the queen on clay and illustrated her prowess with a 6-3 6-4 win at the tournament that rewards its champion not only with a cheque for $120,150 and trophy, but also a Porsche.

This success made Swiatek the first player to defend the Stuttgart title since Angelique Kerber's back-to-back 2015 and 2016 triumphs, and it came in her first tournament back after a rib injury.

The 21-year-old Polish player entered the title match having said she and Ons Jabeur are the tour's best players on clay, and that put her there to be shot at by Australian Open winner Sabalenka, who has climbed to second place in the rankings.

This was the first time a tour-level final has featured the top two women in the world rankings since the 2018 Australian Open final, when Simona Halep beat Caroline Wozniacki.

It was also a repeat of last year's Stuttgart final that Swiatek won comprehensively, dropping only four games, amid a 37-match winning run that would bring her a second French Open title.

The traffic was not quite so one-way this time, but Swiatek was terrific and did not drop serve once.

For Sabalenka, the outcome meant a third consecutive defeat in Stuttgart title matches, having also lost in the 2021 showpiece to Ash Barty.

After Swiatek surged through the opener, she forced a break point at the start of the second set and a Sabalenka double fault handed over the advantage.

Unforced errors were costing the Belarusian, who could not capitalise on a break point in the fourth game of the second set, going on to fling a desperate forehand wide to hand over a 3-1 lead.

Swiatek took evasive action to avoid a fierce Sabalenka smash in the next game, after initially charging towards the net, but she remained firmly in charge.

The title was secured with a ruthless love game on serve, an outmanoeuvred Sabalenka left to watch her opponent drill away a backhand into an empty court.

Reflecting on her injury lay-off, Swiatek said: "It's been such an intense time in the last couple of weeks and tough decisions sometimes, but I'm so happy we're making the right decisions."

Sabalenka, who during the week made no secret of her eagerness to win the Porsche, said: "I'll keep coming back until I get the car."

Defending champion Iga Swiatek will face Aryna Sabalenka in the Stuttgart Open final after Ons Jabeur was forced to retire from their semi-final with a left calf injury.

World number one Swiatek was 3-0 up against Jabeur when her tearful opponent called a medical timeout and ultimately ended the contest early.

It sets up a mouthwatering showdown between top seed Swiatek and second seed Sabalenka, who defeated Anastasia Potapova in straight sets earlier on Saturday.

Jabeur, who struggled to shake off the injury sustained in the first game, said: "The third point, I don't know what happened.

"I was really excited to play Iga today – it's always a fun match between us. I wish her the best luck for the final. I'm sorry guys, I really tried to run, but Iga never makes it easy."

Sabalenka, a beaten finalist in the past two years, held her serve in the opening set against Potapova and twice broke her unseeded opponent to take the lead.

The Belarusian raced 4-0 ahead in the second set and saw out a comfortable 6-1 6-2 victory in a little under an hour to reach her fourth final of the year.

"I think I was really focused, and I think from the very first point I was playing really aggressive," Sabalenka said in her on-court interview. "I didn't give [Potapova] much time. 

"I think that's why the match finished like that quick. But anyway, she's a great player, and I think in the future she's going to be a top player."

Swiatek defeated Sabalenka in last year's Stuttgart final 6-2 6-2 and is aiming to become the first player to defend the title since Angelique Kerber in 2016.

It was a day for comebacks at the Stuttgart Open, with number one seed Iga Swiatek recovering from a set down to beat Karolina Pliskova in the quarter-finals.

Swiatek made a disastrous start, going 4-0 down, and though she broke back once, was unable to find the second as Pliskova took the opening frame 6-4.

The determined Pole stepped up a level though to take the second 6-1, before breaking early in the third.

It was still an improvement for the Czech player, who lost 6-0 6-0 to Swiatek in their only previous meeting in Rome in 2021.

Pliskova kept her opponent honest on her own serve, but Swiatek had too much for the world number 17 as she clinched the decider 6-2.

Aryna Sabalenka also showcased her powers of recovery as she beat Paula Badosa despite going a set down.

The second seed won 4-6 6-4 6-4 in an even contest that saw nine breaks of serve, before the Belarusian eventually got over the line.

Sabalenka is now the player with the joint-most comeback wins over the last two seasons (13) level with Caroline Garcia, though the French star was actually the victim of a comeback herself on Friday.

Garcia won the first set against Anastasia Potapova, before the Russian came back to take it 4-6 6-3 6-3 to set up a semi against Sabalenka.

There was no need for such drama from Ons Jabeur, who eased to a 6-3 6-0 victory against Beatriz Haddad Maia in just 68 minutes to confirm a clash with Swiatek.

Iga Swiatek believes it is "pretty confusing" to see the International Olympic Committee backing sports stars from Russia and Belarus to return to top-level sport while the invasion of Ukraine continues.

Since Russia launched its assault in February 2022, supported by Belarus, many sports have banned athletes from the two countries outright, while tennis has been among those that has largely allowed them to compete but under a neutral flag.

Swiatek, the women's tennis world number one, hails from Poland and has been a vociferous critic of the war and a fervent supporter of Ukraine.

Interim recommendations were issued by the IOC last month to international federations and organisers of events regarding the involvement of Russians and Belarusians.

The Olympic body urged federations to exclude any athletes or support personnel "who actively support the war" and said teams from either country should not be allowed to compete in international sport for now.

However, in a statement, the IOC said it should be "the sole responsibility" of sporting bodies to decide whether individuals can compete, and this should be "based on their sporting merits and not on political grounds or because of their passports".

There is a clear possibility of Russian and Belarusian athletes being allowed to compete as neutrals at the Paris 2024 Olympics, although IOC president Thomas Bach stressed there has been no decision taken on that matter.

Swiatek was asked about the IOC stance after her opening match at the Stuttgart Open, and the 21-year-old said: "Human rights are important, but I always feel like there are values that you have to kind of treat respectfully, and war is not something that we want in the world. I was pretty open about that since the beginning.

"Right now the situation is pretty complicated, because at the beginning of the war there weren't many decisions one way. At first they were kind of banned in other sports, not in tennis.

"Then it changed a little bit, and they are starting to be allowed, the Russian and Belarusian players, which is pretty confusing, because I feel like nothing changed in Ukraine and the cities are still under attack and many Ukrainian athletes are fighting in the war and actually losing their lives.

"It's heartbreaking. I just hope, no matter what the decision is going to be, the sport will be able to kind of put people together and not separate them.

"But there are tensions, so it may be tricky and hard to do. As just one athlete, I don't have full influence on what's going on, so we kind of have to just compete our best no matter what the circumstances are."

Iga Swiatek is through to the quarter-finals of the Stuttgart Open after easing to a 6-1 6-4 win over Zheng Qinwen on her return from a rib injury.

Swiatek had not played since sustaining the issue in the semi-finals of Indian Wells over a month ago, but advanced on Thursday despite stating that she felt "rusty".

The world number one won 84 per cent of points after landing her first serve in as she made up for lost time.

Swiatek also forced eight break points, winning four of them as she took just and hour and 26 minutes to set up a quarter-final with Karolina Pliskova, who bested Donna Vekic in a thriller.

Pliskova looked to be on her way to a routine win as she claimed the first set 6-2, only for the Croatian to take the second via a tie-break.

The decider also went the distance, with Pliskova able to finally put Vekic away 6-2 6-7 (5-7) 7-6 (7-5) to book her clash with Swiatek.

Coco Gauff perhaps paid the price for taking almost three hours to beat Veronika Kudermetova on Wednesday, as the fifth seed fell to a straight-sets loss to Anastasia Potapova on Thursday, going down 6-2 6-3.

Fourth seed Caroline Garcia will go up against Potapova next after she defeated Tatjana Maria 7-6 (7-5) 6-4, while Paula Badosa had few problems seeing off fellow Spaniard Cristina Bucsa 6-1 6-2 and will face second seed Aryna Sabalenka in the last eight.

Iga Swiatek will open the defence of her Stuttgart Open title against Qinwen Zheng after the world number 25's 6-4 6-4 win over Alycia Parks on Monday.

Lucky loser Parks hit eight aces but also 11 double-faults and was undone once in each set as Zheng took a straight-sets victory to tee up a second-round clash with the world number one.

Cristina Bucsa came up with a third-set bagel to join Zheng in round two, having initially made hard work of fellow qualifier Tamara Korpatsch in her 3-6 6-4 6-0 win.

Bucsa will meet the winner of the clash between seventh seed Daria Kasatkina and last year's semi-finalist Paula Badosa.

Meanwhile, Donna Vekic will take on either Karolina Pliskova or Maria Sakkari after she battled to a 7-6 (9-7) 7-6 (7-5) triumph over Ekaterina Alexandrova.

The star-studded line-up sees grand slam winners including Emma Raducanu, Barbora Krejcikova and Jelena Ostapenko get their campaigns underway on Tuesday.

Ons Jabeur, who claimed victory at the Charleston Open earlier this month, kicks off her tournament on Wednesday.

World number one Iga Swiatek believes tennis authorities missed the opportunity to take a stand against the war in Ukraine by banning Russian and Belarusian players.

In response to Russia's invasion of Ukraine last year – which was aided by Belarus – players from both countries were barred from competing at Wimbledon.

Wimbledon was the only grand slam to implement a ban, however, and affected players will be able to return to SW19 this year as neutral athletes after the All England Club reversed the move.

While Swiatek acknowledges a ban may be harsh on Russian and Belarusian players, she feels the sport missed a chance to send a strong message to Vladimir Putin's regime by enacting such a measure. 

"I heard that after World War II, German players were not allowed as well as Japanese and Italian, and I feel like this kind of thing would show the Russian government that maybe it's not worth it," she told the BBC.

"I know it's a small thing because we are just athletes, a little piece in the world, but I feel like sport is pretty important and sport has always been used in propaganda.

"This is something that was considered at the beginning, tennis didn't really go that way, but now it would be pretty unfair for Russian and Belarusian players to do that, because this decision was supposed to be made a year ago.

"I feel like tennis, from the beginning, could do a bit better in showing everybody that tennis players are against the war."

On her Russian and Belarusian colleagues, Swiatek added: "It's not their fault they have a passport like that, but on the other hand, we all have some kind of impact.

"I feel like anything that would help stop the Russian aggression, we should go that way in terms of the decisions the federations are making."

Iga Swiatek has withdrawn from the Miami Open with a rib injury.

The world number was due to defend her title, having won the tournament last year without dropping a set.

However, she will be unable to feature in Florida due to an ongoing rib issue that has plagued her since the Qatar Open in February.

Swiatek reached the semi-finals of the Indian Wells Open last week, losing to eventual champion Elena Rybakina, and hinted at concerns over her condition.

The Pole confirmed on Wednesday that after consulting with her medical team, she will not play her second-round match against Claire Liu on Thursday and will also miss the Billie Jean King Cup, which takes place in April.

"You know that in and after Doha I was struggling with a strong infection," Swiatek said. 

"I was allowed to play, but a strong episode of tough cough led to a rib injury. We were trying to handle it and continue to play as long as it was safe for me. We were analysing the data in the last [few] days and my doctor prepared my diagnosis.

"Unfortunately, I'm still feeling a lot of discomfort and pain and I can't compete.

"I will keep you updated about where I play next, because it depends on my process of recovering and the recommendation of my medical team. 

"I have the best team behind me, we only need some time to deal with the injury. It's a truly difficult call to not play in Miami and the Billie Jean King Cup, but health is the most important [thing].

"I'm grateful this is the first health issue in a long time and I was able to compete in perfect shape for so long, but that's sports, it happens sometimes, without our control. 

"Time to accept it and get well as soon as possible."

Swiatek will be replaced in the women's draw by lucky loser Julia Grabher.

The 21-year-old will now hope to be fully fit in time for the clay-court season, including the French Open, where she is the reigning champion.

Aryna Sabalenka received "hate" in the dressing room after Russia's invasion of Ukraine.

Sabalenka finished as runner-up at Indian Wells last week, losing to Elena Rybakina, who she defeated in the Australian Open final in January.

Born in Belarus, an ally of Russia, the 24-year-old revealed ahead of her Miami Open campaign that "weird conversations" had come from members of other players' teams, rather than her fellow pros.

"It was really tough for me because I've never faced that much hate in the locker room," she said. "There are a lot of haters on Instagram when you're losing matches, but in the locker room I've never faced that.

"I had some, not like fights, but I had some weird conversations with, not the girls, but with members of their team. It was tough. It was a tough period. But now it's getting better.

"It was really tough to understand that there's so many people who hate me for no reason. I did nothing."

Players from Russia and Belarus have been classed as neutral since the invasion, and were banned from last year's Wimbledon.

Ukraine's Lesia Tsurenko pulled out of her match against Sabalenka at Indian Wells after suffering a panic attack following a conversation she had with WTA chief executive Steve Simon about tennis's response to the invasion.

World number one Iga Swiatek had called for greater support for Ukrainian players as a result of the conflict but another Belarusian, Victoria Azarenka, disagreed.

"There are certain players that have different feelings and behaviours. Overall, I don't necessarily share the same opinion as Iga does," Azarenka said.

"I'd encourage her to look at the things that have been done before she makes comments. As a player council member I'm happy to provide the facts. That would be a more appropriate way to have that conversation."

Camila Giorgi progressed into the Miami Open second round despite blowing a 5-0 third-set lead as she edged past veteran Kaia Kanepi in the equal-longest main draw match of the year on Tuesday.

The Italian world number 44, who won February's Merida Open, outlasted the Estonian 7-6 (7-4) 6-7 (4-7) 7-6 (7-4) in three hours and 32 minutes.

The length was equal to the Erika Andreeva-Harriet Dart first-round match at the ATX Open last month for the longest this WTA season.

But Giorgi could have had an earlier finish, leading 5-0 in the decider before Kanepi hit back by winning the next five games, only for the Italian to rally in the tie-break, converting her fourth match point.

Giorgi, who blew match points at 5-3 and 5-4, will take on three-time Miami Open winner and 2023 Australian Open semi-finalist Victoria Azarenka in the second round.

Russian 34-year-old Evgeniya Rodina produced the upset of the day's play, beating 37th-ranked Bernarda Pera 6-3 6-4 in 73 minutes and will take on 20th seed Magda Linette in the second round.

Rodina is currently ranked 369th in the world having returned to the WTA Tour midway through last season after a two-year absence, having reached a career-high 67th in May 2019.

World number 39 Elise Mertens eased into the second round with a 6-1 6-4 win over USA's Alycia Parks, setting up a second-round clash with eighth seed Daria Kasatkina.

World number 43 Yulia Putintseva bowed out prematurely, going down 7-6 (7-4) 6-2 to Canada's Rebecca Marino, who advanced to face sixth seed Coco Gauff.

Teenager Linda Fruhvirtova, ranked 50th in the world, also suffered a shock loss, beaten 6-2 4-6 6-4 by 172nd-ranked Canadian qualifier Katherine Sebov, while Laura Siegemund won 6-3 6-4 over 52nd-ranked Mayar Sherif

Katerina Siniakova withdrew due to injury despite winning the first set against USA's Claire Liu, with scores at 6-3 3-3. Liu's prize is a second-round meeting with top seed and reigning champion Iga Swiatek.

Iga Swiatek is unsure whether she will be fit to defend her Miami Open title after a rib injury hampered the world number one during a semi-final defeat at the Indian Wells Open.

A savage 6-2 6-2 thrashing at the hands of Wimbledon champion Elena Rybakina came while Swiatek was suffering physically.

She was emphatically outplayed, and how much of a factor the injury was is unclear, with tests in the coming days set to dictate what happens next for the 21-year-old Pole.

Swiatek was asked about what Rybakina did well and said: "I feel like it's still more me and my mistakes. I'm also not feeling 100 per cent physically. I have a little discomfort in my rib, and we're going to consult with the medical team."

She said she would use the days leading up to next week's event in Miami as a chance to recover.

"In terms of the rib, we'll see, because I still have to run some tests and see what's going on. I don't know yet," she said after Friday's defeat.

"Honestly, I haven't played with a lot of injuries. It's a new situation for me. The last time I played with an injury, the only tournament I can remember, is Roland Garros in 2019, so I was pretty young.

"Now it's a totally different level. I have been playing, so there has been some fatigue all the time. I would say it's kind of constant, but I'm pretty sure that tomorrow or the day after will help in recovery."

Asked whether it was a problem that could prevent her playing in Miami, Swiatek said: "No, for now I'm preparing to play, but we'll see what the next days are going to tell us. I don't know yet."

Swiatek last year won both Indian Wells and Miami to complete the 'Sunshine Double' in the early stages of a 37-match winning run that ended with a third-round Wimbledon defeat to Alize Cornet.

While Swiatek seeks medical expertise, Rybakina goes on to face Aryna Sabalenka in Sunday's Indian Wells trophy match, a repeat of the Australian Open final that Sabalenka won to earn a first grand slam singles title.

It is the third time this century that the WTA Indian Wells showpiece match has featured the same line-up as the Melbourne Park final after 2000 (Lindsay Davenport and Martina Hingis) and 2012 (Maria Sharapova and Victoria Azarenka).
