Coco Gauff lost the first set in 20 minutes but roared back to stun seventh seed Elise Mertens – as Iga Swiatek also staged a comeback at the Viking International in Eastbourne.

Playing late in the day, Gauff was picked apart by Mertens to begin with, and also trailed by a break in the second set, but the 17-year-old American rising star pulled off a 0-6 7-6 (7-4) 7-5 first-round win.

Seeds Elina Svitolina, Bianca Andreescu and Swiatek all came through three-set matches on a busy day, but Karolina Pliskova was not so fortunate in her opener.

Winner of the grass-court event in 2017 and 2019, Pliskova arrived as the defending champion after last year's edition was cancelled amid the coronavirus pandemic.

However, her hopes of a repeat triumph came to an early end, beaten in three sets by qualifier Camila Giorgi.

The fifth seed was in charge initially against an opponent she had prevailed against in five of their six previous meetings, yet Giorgi produced an impressive response having fallen behind – aided by a strong service performance – to win 2-6 6-2 6-2.

Svitolina, the second seed, had lost in her previous two appearances in the main draw, and it appeared history could be repeated when Paula Badosa claimed the opening set against her.

Yet the second seed recovered to level, then dominated the tie-break in the decider to triumph 4-6 6-1 7-6 (7-1) and set up a second-round meeting with Elena Rybakina, who edged out wildcard Harriet Dart in three sets.

Andreescu, meanwhile, recorded her maiden win on grass in the main draw of a WTA tournament. The Canadian was made to work for it by Christina McHale, eventually coming out on top by a 6-4 2-6 6-2 scoreline.

Swiatek eventually saw off the challenge of Heather Watson after two hours and 42 minutes on court, a 6-3 6-7 (4-7) 7-5 triumph making sure of a place in the last 16. Watson led 4-1 and 40-0 in the decider but could not finish off last year's French Open champion.

This year's Roland Garros runner-up, Anastasia Pavlyuchenkova, meanwhile, was beaten 6-1 6-3 by Jelena Ostapenko.

At the Bad Homburg Open, second seed Victoria Azarenka defeated fellow Belarusian Yuliya Hatouka 7-5 6-0 to reach the last 16.

Jessica Pegula bowed out, though, as the American – seeded third – went down in a three-set tussle against Katerina Siniakova.

Jessica Pegula got the better of Karolina Pliskova once again as she knocked the fourth seed out of the bett1open on Thursday.

The American beat the former world number one 7-5 6-2 in Berlin, setting up a quarter-final clash with Victoria Azarenka.

It is the fourth time this season Pegula has defeated Pliskova.

Azarenka was also a straight-sets winner, overcoming Angelique Kerber in a battling 6-3 7-5 victory.

The two-time Australian Open champion was 4-1 down in the second set but roared back to prevail over Kerber for the 10th time in 11 matches.

Garbine Muguruza enjoyed a 6-4 6-3 victory over Elena Rybakina and will take on Alize Cornet next, while Ludmilla Samsonova downed Veronika Kudermetova by the same scoreline and will now face Madison Keys.

Ashleigh Barty described her retirement from Thursday's second-round clash against Magda Linette at the French Open as "heartbreaking". 

Top seed Barty required medical attention during her first-round win over Bernarda Pera two days earlier, with a hip injury the cause for concern.

The 25-year-old – back at Roland Garros for the first time since winning her maiden grand slam title in Paris in 2019 – vowed to "play through the pain barrier", yet the injury prevented her from continuing when 1-6 2-2 down against her Polish opponent, who will face Ons Jabeur in the next round. 

The Australian's retirement throws the draw wide open, with both of the top seeds now out after Naomi Osaka decided to withdraw amid her disagreement with tournament organisers.

Barty's clay-court season ended with a title in Stuttgart, a runner-up finish in Madrid and an appearance in the quarter-finals in Rome, and she could scarcely hide her disappointment at the way things ended for her in the French capital. 

"It's heartbreaking," she told a media conference. "I mean, we have had such a brilliant clay-court season, and to get a little bit unlucky with timing and have something acute happen over the weekend and just kind of run out of time against the clock is disappointing. 

"It won't take away the brilliant three months that we have had, as much as it hurts right now.

"We did everything, absolutely everything we could to give myself a chance. It was a small miracle that we were able to get on court for that first round.

"I just tried to give myself a chance and see how it felt. Obviously practicing, we've had our restrictions and essentially tried to stay as fresh as possible and not aggravate it in any way, but in a match that's unavoidable at times.

"It got worse today and it was becoming at the stage where it was unsafe. As hard as it is, it had to be done. Right from the first game, I was battling the pain, and it just became too severe."

SVITOLINA CRUISES THROUGH, PLISKOVA DUMPED OUT

Fifth seed Elina Svitolina booked a third-round meeting with Barbora Krejcikova after seeing off Ann Li 6-0 6-4. 

Svitolina landed 74 per cent of her first serves and struck 10 winners to cruise past the American in the opening set. 

Li bounced back in the second, roaring into a 4-1 lead, but Svitolina clawed her way back to ensure she reached at least the third round in seven of her nine appearances at Roland Garros. 

Svitolina, who overturned a 2-5 deficit in the second set to beat Oceane Babel in the first round, said: "In the end, what I'm really happy with is the way that I was down in both matches in the second set and found a way. 

"I found a good level and didn't give up on the second set. That was a really good point for me, and I was really playing composed in both matches. It was two different players, but I was really happy that I could win in two sets in both matches."

Up next is Krejcikova, who overcame Ekaterina Alexandrova 6-2 6-3.

There is no place in the third round for ninth seed Karolina Pliskova, who was soundly beaten 7-5 6-1 by Sloane Stephens, while number 13 seed Jennifer Brady battled past Fiona Ferro 6-1 1-6 6-4. 

KENIN WINS BATTLE OF THE AMERICANS

Fourth seed Sofia Kenin defeated fellow American Hailey Baptiste, a qualifier who won four matches in Paris on her French Open debut, 7-5 6-3. 

Kenin will now face another compatriot in 28th seed Jessica Pegula, who beat Tereza Martincova 6-3 6-3.

Elsewhere, defending champion Iga Swiatek thumped Rebecca Peterson 6-1 6-1, Coco Gauff got the better of Wang Qiang 6-3 7-6 (7-1), and Elise Mertens edged out Zarina Diyas 6-4 2-6 6-4.

Ashleigh Barty acknowledged it will be a "tough" week for her at the French Open as she plans to play through the pain at Roland Garros.

Barty – champion in Paris back in 2019 – had to take a medical time out during her first-round tie with Bernarda Pera on Tuesday.

The Australian world number one struggled with a hip issue, yet still progressed with a 6-4 3-6 6-2 win.

"It's going to be a little bit tough this week. I think over the weekend we had a bit of a flare-up through my left hip, which obviously just needed a bit of help today, needed some assistance to try and release it off as best I could," the 25-year-old said in her post-match news conference.

"I'm not going to hide behind the fact I'm not quite 100 per cent but I can guarantee that I will go out there with the right attitude every day and be really accepting of that and give it a crack no matter what.

"We're confident in that we can get my body to a point where I'm able to compete. We're here, we're fighting, we're in with a chance, and that's all we can do."

Magda Linette is next up for Barty on Thursday, the Polish player defeating Chloe Paquet in straight sets.

COCO CARRIES ON HER FORM AS SEEDS REACH ROUND TWO

Fresh from her triumph in both the singles and doubles in Parma, and a run to the Internazionali BNL d'Italia semi-finals, Coco Gauff started her campaign with a tough win over qualifier Aleksandra Krunic.

Gauff, the 24th seed, certainly had to do it the hard way, with the 17-year-old clawing back four set points in the opener, but some brilliant first serves – she landed 71 per cent of them – got her through in straight sets.

It brought up Gauff's first win at a grand slam as a seed. She is ranked at 25th in the world, making her the youngest American woman to make it into the top 25 since Serena Williams in 1998. 

Wang Qiang will face Gauff in round two in what is a repeat of the Parma final.

Meanwhile, three other big names also made it through. Former world number one and 2017 French Open semi-finalist Karolina Pliskova overcame her close friend Donna Vekic 7-5 6-4, while fellow Czech Karolina Muchova came from behind to beat Andrea Petkovic 1-6 6-3 6-4.

With Petkovic's exit, there are no female players from Germany in the second round at Roland Garros for the first time since 1958.

Fifth seed Elina Svitolina is also through to round two after coming back from a break down in the second set to beat teenager Oceane Babel 6-2 7-5.

"It's a first time for her to play here in the main draw of the grand slam and to face the sixth player in the world it's extremely tough," Svitolina said of her young opponent.

"I think she dealt very well with it and she went for her shots in the second set and made life very difficult for me."

SUAREZ NAVARRO MAKES COMEBACK

Carla Suarez Navarro overcame Hodgkin lymphoma earlier this year, after revealing last September that she had been diagnosed with the rare cancer.

Suarez Navarro won that battle and is now cancer free, but in what she said will be her last appearance at Roland Garros, she slipped to a defeat to 2018 finalist Sloane Stephens.

The Spaniard took the first set 6-3 and forced a tiebreaker in the second, but it was Stephens who edged it before taking that momentum into the decider to claim a 3-6 7-6 (7-4) 6-4 win.

Iga Swiatek sealed a place in the world's top 10 in style on Sunday, thrashing Karolina Pliskova without dropping a game in a stunning Internazionali BNL d'Italia final.

The reigning French Open champion was in ruthless form in the showpiece match, dismantling the ninth seed 6-0 6-0 in just 46 minutes on the Rome clay.

Pliskova simply had no answer as she suffered the first double-bagel loss in a WTA final since 2016, back when Anastasija Sevastova was on the receiving end against Simona Halep in Bucharest.

Swiatek showed no mercy to her opponent, losing just 13 points during a lopsided contest. She did face two break points in the third game of the second set, but quickly recovered to hold serve.

The victory secures a third career title for the teenager from Poland, who also triumphed in Adelaide earlier this year.

"I'm really really happy. I'm kind of overwhelmed because at the beginning of this tournament I wouldn't even dream of winning," Swiatek said in her on-court interview.

"It was super tough. We had to fight a lot of stuff.

"Obviously Karolina had a great run here and in previous years she's showing she's a really consistent player."

The new champion had needed to play twice on Saturday due to rain delays during the tournament, overcoming both Elina Svitolina and Coco Gauff in straight sets to progress to the final.

Those results came after a last-16 scare against Barbora Krejcikova, Swiatek twice having to save match points before eventually prevailing in a deciding set.

"I'm really happy we've been able to play with fans because you gave me a lot," Swiatek, who is certain to be inside the top 10 when the updated rankings are released on Monday, said.

"Everything happened during this week. I've been playing two matches in a day, saving set points, saving match points, and you [the crowd] helped me a lot because it's tough.

"I want to thank people that are not here, my family and my cat, I am always thinking about her."

French Open champion Iga Swiatek beat Elina Svitolina and Coco Gauff on a hectic Saturday to set up a clash with Karolina Pliskova in the Internazionali d'Italia final.

The Polish teenager began her day with a 6-2 7-5 morning victory over fifth seed Svitolina, twice a winner of this tournament in Rome.

It was a match that was carried over from Friday's schedule after rain interrupted play, and Swiatek delivered a convincing performance.

That set up the semi-final clash with Gauff, the 17-year-old American who was competing at this stage of a WTA 1000 event for the first time, having been gifted her last-four place when Ash Barty abandoned their quarter-final match due to injury on Friday.

There was no sign of fatigue from Swiatek as the 19-year-old powered to a 7-6 (7-3) 6-3 victory in a battle of the leading teenage stars of the women's game, who faced each for the first time in what could be a long rivalry.

Swiatek said: "I felt really good today. It's a big difference between my previous matches and today. I was able to beat Elina, so that shows that my game is here, I'm ready for anyone. It gave me a real confidence boost."

Quoted on the WTA website, the 15th seed added: "It's always hard to play against a young superstar, especially when I'm not used to that because I was always the youngest one.

"I just tried to have a high level of energy, even though it was my second match."

Between her two matches, Swiatek would have learned it was Pliskova waiting in the final, as the Czech ninth seed defeated Croatian Petra Martic 6-1 3-6 6-2 to keep up her remarkable record in the Italian capital.

Pliskova won the Rome title in 2019 and was runner-up to Simona Halep last year, but the 29-year-old former world number one has not been to a final since this event unusually took place in September of last year, having been delayed due to the pandemic.

Swiatek won as a major outsider at Roland Garros in October, defying her world ranking which at the time was a lowly 54th, and will face, in Pliskova, a player who has yet to win a grand slam title, a glaring absence amid an otherwise stellar career.

Against Gauff, Swiatek made 25 winners and just 16 unforced errors, a healthy ratio, and took three of her four break-point opportunities.

She sealed victory on a third match point, a big backhand forcing a stretching Gauff to chip beyond the baseline.

Gauff hit seven aces but also five double faults and had 33 winners and 32 unforced errors in the contest.

Ash Barty dramatically abandoned her Internazionali d'Italia quarter-final against Coco Gauff on Friday due to a right arm injury.

The world number one was leading 6-4 2-1 in Rome when, with her left thigh also heavily strapped, she pulled out of the match following talks with a trainer.

Barty's decision was precautionary as she will begin her French Open campaign in a little over two weeks' time, bidding to regain the title she won two years ago.

The scare came just hours after world number three Simona Halep announced she tore a calf muscle this week, putting the Romanian's Roland Garros prospects in some doubt.

Providing an update after the match with Gauff, which was interrupted by a rain delay, Australian Barty said: "The pain was becoming too severe so it was important to listen to my body and do the right thing knowing we have a slam."

Gauff, who had hit 12 winners to 15 unforced errors prior to her opponent's withdrawal, will now compete in her first career WTA 1000 semi-final.

Karolina Pliskova remained on course for a second Rome triumph in three years, after saving three match points to edge out Jelena Ostapenko.

The 2019 champion, who also finished runner-up last year, was 5-4 down in the final set when digging deep to hold off her 49th-ranked opponent.

The thrilling match went to a tie-break and Pliskova reeled off seven straight points after losing the opener to advance 4-6 7-5 7-6 (7-1).

"I'm just proud of how I fought," Pliskova said at her post-match news conference. "I'm happy that I stayed in there and fought until the end.

"We played last month, so I knew what was going to be happening. You can never get ready for some of the balls which she's playing."

Petra Martic stands between Pliskova and a place in the final for the third year running after the Croatian defeated Jessica Pegula 7-5 6-4.

Pegula eliminated Naomi Osaka earlier in the week but was second best against Martic, who progressed in one hour and 40 minutes.

Martic trailed 2-0 in the opening set before twice breaking Pegula to move 3-2 in front, but her opponent hit back to make it 5-5 in a tight contest.

However, Martic managed to break in the 11th game and served out the set, before showing her steeliness in the second to remain on course for a maiden WTA 1000 crown.  

Naomi Osaka quickly adapted to playing again on clay as she was among the seeds to triumph in Friday's action at the Madrid Open.

Osaka had not featured on the red dirt since a third-round exit at the 2019 French Open, missing out on competing on the surface last year due to injury.

This year's Australian Open champion stumbled out of the blocks against Misaki Doi, quickly falling 3-0 behind in the opener, but recovered from the early setback to prevail in straight sets.

The second seed hit 26 winners in a 7-5 6-2 triumph over her compatriot, who has now lost all three of their meetings on the WTA Tour.

"You obviously want to play well against a player that's from the same country," Osaka said.

"I never really know what to expect because I feel like she always plays better when I play against her, so it's a bit tough to manage controlling my emotions. But I think I was able to do it pretty well."

Simona Halep also won in her opener at the event, the third seed racing through the first set before holding off a fightback from Sara Sorribes Tormo in the second.

Halep – who needed 83 minutes to clinch a 6-0 7-5 victory – has been crowned champion twice in Madrid, the first time coming in 2016 before she returned a year later to successfully defend the title.

Aryna Sabalenka wasted little time in seeing off the challenge of Vera Zvonareva, the fifth seed producing 37 winners in a 6-1 6-2 win, her first ever in the event.

Maria Sakkari found the going much tougher before eventually ousting Amanda Anisimova, losing the first seven games in a row before rallying for a 0-6 6-1 6-4 triumph.

Daria Kasatkina was also pushed in her opener, with a 4-6 6-4 7-6 (7-1) win over Irina-Camelia Begu taking just over three hours.

Karolina Pliskova had to go the distance after falling a set behind against Coco Gauff, while two-time finalist Victoria Azarenka came out on top in a deciding set against Ekaterina Alexandrova.

In the final match on a busy day, Jennifer Brady won 6-2 6-4 in an all-American clash with Venus Williams.  

World number one Ash Barty survived a scare to reach the semi-finals of the Stuttgart Open with a 2-6 6-1 7-5 win over Karolina Pliskova.

The Australian started slowly in the quarter-final of the WTA 500 tournament on Friday as Pliskova broke her serve twice in taking the first set, before Barty hit back with three breaks of her own to force a decider.

Barty was two points away from losing on five occasions as world number nine Pliskova served for the match at 5-4 in the final set.

But she broke the Czech's resolve eventually, sealing victory when Pliskova hit the ball long after a baseline rally.

The win was Barty's eighth consecutive victory over a top-10 opponent and she said in a media conference afterwards that facing top players in the world brings the best out of her.

"When you come up against top-10 opponents, you have to go to that level above to be able to compete. They force you to bring your best," Barty said.

"With a lot of the girls in the top 10, we've had plenty of matches that have gone either way, different experiences, so each time I love that challenge of testing myself against the best."

Barty will face Elina Svitolina in the semi-finals after she saved two match points to claim a 6-7 (4-7) 7-5 6-2 victory over Petra Kvitova.

In the other half of the draw, Simona Halep breezed through to the semi-finals with a 6-1 6-4 win over Ekaterina Alexandrova.

Halep clinically closed out the first set, and although Alexandrova showed more fight in the second, the world number three did not allow her a route back into the match.

Halep will face Aryna Sabalenka following the Belarusian's 7-5 4-6 6-1 win over Anett Kontaveit.

In the Istanbul Cup, top seed Elise Mertens secured her place in the semi-finals with a 6-4 6-4 win over Katerina Siniakova.

Mertens will face Veronika Kudermetova who fought back from a set down to clinch a 2-6 6-3 6-3 win over Ana Bogdan.

The other semi-final will see Sorana Cirstea play Marta Kostyuk. Cirstea progressed after Fiona Ferro, trailing 6-4, retired through injury while Kostyuk beat Ana Konjuh 7-5 4-6 6-3.

Naomi Osaka did not raise a sweat en route to the Miami Open last 16 as Garbine Muguruza moved through but Sofia Kenin and Karolina Pliskova bowed out.

Australian Open champion and second seed Osaka benefited from a walkover after qualifier Nina Stojanovic withdrew ahead of Sunday's clash due to a right thigh injury.

Elise Mertens will face Osaka following the 16th seed's 6-2 0-6 6-2 win against Anett Kontaveit.

Two-time grand slam winner Muguruza rallied past Russian wildcard Anna Kalinskaya at the WTA Premier event.

However, fourth seed Kenin was sent packing as sixth seed Pliskova was tamed by nemesis Jessica Pegula in Miami.

MUGURUZA STAYS HOT

Spanish star Muguruza dug deep to earn her tour-leading 20th win of the season.

Former world number one Muguruza – the 12th seed – prevailed 4-6 6-3 6-4 against Kalinskaya, having trailed 3-0 in the final set.

"I brought my fighting spirit and I could match the level of fighting against Anna, and very happy to go through these tough matches," Muguruza said following two hours, 41 minutes on court.

"Doesn't matter if you play pretty or you play ugly, but you stay strong and you go through these rounds. That gives me an opportunity to feel better and to have another chance."

Muguruza – who has the most final appearances this season with three, having won the Dubai Tennis Championships and finished runner-up at the Qatar Open and Yarra Valley Classic – will next face eighth seed Bianca Andreescu.

Former US Open champion Andreescu overcame fellow seed Amanda Anisimova 7-6 (7-4) 6-7 (2-7) 6-4.

KENIN'S WOES CONTINUE

It has been a rough 2021 for American star Kenin.

Stunned in the second round of the Australian Open – in her title defence – Kenin then crashed out of the Phillip Island Trophy at the first hurdle.

Kenin rallied to beat Andrea Petkovic first-up in Miami, but the 22-year-old was beaten 6-4 4-6 6-4 by 27th seed Ons Jabeur.

Jabeur and Sara Sorribes Tormo – who shocked 21st seed Elena Rybakina 6-1 3-6 6-2 – will meet for a spot in the quarter-finals.

PLISKOVA FALLS TO PEGULA… AGAIN

For the third time this past month, 2019 Miami Open runner-up Pliskova went down 6-1 4-6 6-4 to 29th seed Pegula.

Australian Open quarter-finalist Pegula conquered Pliskova in Doha and Dubai before repeating the feat in Miami on Sunday.

"I played her a lot the last three weeks, three tournaments," Pegula said. "I kind of expected her to play well there. Even when I was up I still felt like she could easily come back just because she plays so aggressive and she serves well."

After reeling off the final four games, Pegula set up a last-16 showdown with 23rd seed Maria Sakkari, who dismantled qualifier Liudmila Samsonova 6-0 6-1.

Petra Kvitova moved a step closer to a second successive appearance in the Qatar Open final after overcoming Anett Kontaveit on Thursday. 

Two-time Wimbledon champion Kvitova lost to Aryna Sabalenka in the 2020 final but has looked on top form throughout the week in Doha. 

Kontaveit proved a tough opponent for the fourth seed, however, and Kvitova – the 2018 champion – needed three sets to progress 6-3 3-6 6-2. 

"I'm really glad that after losing the second set, which I probably didn't play the best, I started very well in the third," said Kvitova. 

"I learned that the return was pretty good from my side. I was going for it – first point, first shot – and I think that made a big difference. In the rally, it was 50-50 and anybody could win it, but when I put the pressure from my return, it was really very nice."

Her reward is a semi-final tie with qualifier Jessica Pegula, who caused an upset by defeating second seed Karolina Pliskova 6-3 6-1. 

Pegula reached the Australian Open quarter-finals last month and played with supreme confidence to oust the 2017 champion and reach her maiden semi-final at a WTA 500 event. 

The other half of the draw will see Victoria Azarenka taking on Garbine Muguruza. 

Azarenka triumphed 6-2 6-4 over top seed Elina Svitolina, with the two-time Doha champion maintaining her unbeaten record against the Ukrainian to reach the 60th WTA semi-final of her career. 

Muguruza, meanwhile, battled past Maria Sakkari 6-3 6-1 to complete the last four. 

At the Lyon Open, French duo Kristina Mladenovic and Clara Burel booked their places in the last eight, beating Margarita Gasparyan and Aliaksandra Sasnovich respectively. 

Spaniard Paula Badosa awaits Mladenovic, while teenage wildcard Burel takes on compatriot and second seed Fiona Ferro in what is her first WTA quarter-final. 

There were also victories for Greet Minnen and Viktorija Golubic.

Garbine Muguruza made clear she is "fighting for trophies" on the WTA Tour after knocking out defending champion Aryna Sabalenka at the Qatar Open. 

Muguruza prevailed in a high-quality contest that required a third set to decide the outcome, the world number 16 and two-time grand slam champion eventually triumphing 6-2 6-7 (7-5) 6-3 after two hours, 18 minutes on court. 

Sabalenka had won their only previous meeting but the third seed saw her hopes of retaining the trophy dashed, not helped by only managing to convert four of the 13 break-point opportunities she created in the match. 

Muguruza – who matched 41 winners with the same number of unforced errors – finished in fine style, claiming the final four games in a row to set up a meeting with Maria Sakkari, who defeated Madison Keys in straight sets. 

"I'm very motivated to play top players," Muguruza said in her post-match press conference, according to the WTA Tour's website. "Like everybody, I worked hard. I'm fighting for trophies, to play well in big tournaments, in good tournaments. 

"Today I was facing a top player, and I knew I have to go out there with a big, fighting spirit, and be strong to be able to win against these tough opponents." 

While the 2020 winner is no longer involved, former champions Victoria Azarenka and Petra Kvitova both made it beyond the second round with straight-sets wins in Wednesday's action. 

Azarenka, who claimed the title in 2012 and then returned to successfully retain it a year later, saw off qualifier Laura Siegemund 6-4 6-2. 

Kvitova, meanwhile, eased past Anastasia Pavlyuchenkova. The fourth seed went all the way in 2018 and is now into the last eight this year – a 6-1 6-3 result paving the way for a clash with Anett Kontaveit.

Top seed Elina Svitolina is also through – and will face Azarenka next – after needing little over an hour to defeat Misaki Doi 6-1 6-2.

Karolina Pliskova, the second seed, found life far tougher against Ons Jabeur however, eventually coming out on top 6-4 4-6 7-5 in a thriller.

Meanwhile, at the Lyon Open, second seed Fiona Ferro progressed to the last eight on home soil after opponent Tereza Martincova was forced to retire when 4-1 down in the second set, having already lost the opener too.

Alize Cornet is another French favourite hoping to make home advantage tell in the tournament; the fifth seed rallied from a set down to beat compatriot Clara Burel 1-6 6-1 6-3. 

Ash Barty may have her focus on winning the Australian Open right now but suggested a career change could be on the cards in the future.  

The world number one made sure she will still be competing during the second week of the tournament in Melbourne by beating Ekaterina Alexandrova in straight sets.  

But, having played international cricket for Australia before switching to tennis, could the multi-talented Barty be considering trying another sport?  

Elsewhere in Saturday's action, Karolina Pliskova lost her cool – and also a couple of rackets – as she slipped to defeat against the impressive Karolina Muchova in an empty Rod Laver Arena, with fans not able to be present due to a five-day lockdown in the state of Victoria.

Elina Svitolina had no such problems in her third-round match, while Elise Mertens was victorious in just over an hour against Belinda Bencic. Jennifer Brady ended Slovenian qualifier Kaja Juvan's run in the first grand slam of the year.

AUSSIE RULES, OK? 

After winning 6-2 6-4 without ever needing to be at her peak, Barty was cheekily asked by former doubles partner Casey Dellacqua – now working in the media – whether she may be set to switch paths again, once her tennis career has come to an end.  

Australian rules football was the answer – but Dellacqua maybe got more than she bargained for from her former playing partner during the on-court interview. 

"I thought it was our deal, we're going to AFLW. It's ABCD [the nickname for the pairing from their doubles career]. We come as a package, and I know we will be going to the [Richmond] Tigers that is for sure," Barty said. "You can't go to Carlton. You have to come to the 'Tiges' with me."

Dellacqua replied: "I need to get out there and start practicing some kicking, but you are good. I would love to do that one day." 

For Barty, though, the next challenge facing her is Shelby Rogers, who knocked out 21st seed Anett Kontaveit during the evening session.  

MAKING A RACKET 

A disgruntled Pliskova was not impressed when punished for smashing up a racket during her match with compatriot Muchova. 

Having received a warning when throwing a racket to the floor during the course of the final game in the opening set, the sixth seed then vented her frustration again on another while in the players' tunnel.  

An official witnessed the incident and reported it to chair umpire Alison Hughes, who punished the Czech with a point penalty before she began serving to open the second set.  

"It's off court, I'm allowed to do what I want," Pliskova insisted when querying the decision to the official. She would go on to hold before recording two successive breaks, yet somehow failed to force a decider.  

Muchova rallied from 5-0 down in sensational fashion, winning seven games on the spin to triumph 7-5 7-5 to make it through to the last 16.

CONTRASTING PROGRESS FOR SEEDS

Svitolina has still yet to drop a set in the tournament after overcoming 26th seed Yulia Putintseva by a 6-4 6-0 scoreline.  

The fifth seed was twice down a break in the first set but, after eventually coming out on top to take a 1-0 lead, breezed through the second in a hurry.  

"She has a very different game style from what I played my last two rounds, so it wasn't easy at the beginning to adjust," Svitolina said. "As soon as I was feeling better, I just stepped my game, and it was quite a comfortable win after." 

Next up will be Jessica Pegula, who is through to the fourth round at a slam for the first time in her career after thrashing Kristina Mladenovic 6-2 6-1.  

There was also success for another American in the main draw, Brady defeating Juvan in straight sets. Her reward is a clash with Donna Vekic, the 28th seed having to save a match point before eventually seeing off Kaia Kanepi 5-7 7-6 (7-2) 6-4 after two hours and 38 minutes on court. 

Sofia Kenin's title defence came to a shock end in the second round of the Australian Open, where world number one Ash Barty advanced amid injury concerns.

Kenin was looking to become the first woman to defend her crown at Melbourne Park since Victoria Azarenka in 2013, instead, she was a high-profile casualty in warm conditions on Thursday.

Barty, who lost to Kenin in last year's semi-finals in Melbourne, stayed alive with a straight-sets win over fellow Australian Daria Gavrilova.

Former world number one Karolina Pliskova also progressed beyond the second round as fifth seed Elina Svitolina blitzed American sensation Coco Gauff.

KENIN OUSTED IN BOILOVER

The American star arrived at the year's first grand slam with high expectations and looking to become the first woman to go back-to-back at a major since Serena Williams in 2016.

But fourth seed Kenin fell to experienced Estonian Kaia Kanepi 6-3 6-2, having tallied 10 winners and 22 unforced errors in windy conditions in Melbourne - the scene of her breakthrough slam more than 12 months ago.

It was Kenin's first defeat to a player ranked outside the top 50 since going down to then-number 54 Iga Swiatek in the 2020 French Open final.

Asked why she was nervous pre-match, Kenin told reporters: "It's like the outside pressure. I felt really nervous. I haven't felt my game for, I don't know how long, but I haven't really felt my game so well, even in my first round. 

"I played well, but still haven't felt 100 per cent game-wise. It's obviously tough."

STRAPPED THIGH? NO WORRIES FOR BARTY​

Barty's left thigh was heavily strapped amid concerns but the 2019 French Open champion still booked her spot in the third round with a 6-1 7-6 (9-7) win over countrywoman Gavrilova.

The first Australian woman to reach the semi-finals in Melbourne since 1984, following last year's run, Barty gave up a 5-2 lead in the second set before saving two set points in the tie-break.

Reflecting on Kenin's surprise exit, Barty talked up the standard of the WTA Tour.

"There are no easy matches," said Barty, who next meets 29th seed Ekaterina Alexandrova for a spot in the round of 16. "There are no easy matches in any tour event, any slam, anything. I think every time you walk on the court, you have to try and be able to bring your best tennis to be able to compete with everyone. 

"That's just the level that there is now on the women's side. That's something really exciting about women's tennis now, is that every single match, it's a fair match. You go out there, you play hard, you try to do the best that you can."

PLISKOVA AVENGES LOSS, SVITOLINA TOO GOOD FOR GAUFF

Beaten by Danielle Collins in the third round of the Yarra Valley Classic just eight days ago, sixth seed Pliskova got the better of the 2019 Australian Open semi-finalist this time around.

Pliskova - also a semi-finalist at Melbourne Park two years ago - defeated Collins 7-5 6-2 and next plays 25th seed Karolina Muchova.

"I just played better in some moments, which I didn't last week. Then she was not playing that well as she did last week," Czech star Pliskova said. "I knew if I at least maintain little bit, just play at least similar as I was playing last week, I knew it's going to be difficult for her to repeat what she played last week. I think she really played great."

Owning a 6-1 record in the second round at Melbourne Park - falling only at this stage in 2016 - Svitolina produced a mature performance to conquer 16-year-old star Gauff 6-4 6-3 on centre court as 26th seed Yulia Putintseva awaits. 

Elsewhere, seeds Belinda Bencic, Elise Mertens, Anett Kontaveit, Jennifer Brady and Donna Vekic moved through.

A "calmer" Garbine Muguruza made a fine start at the Australian Open, while defending champion Sofia Kenin was left annoyed despite her victory.

A finalist at the Yarra Valley Classic last week, Muguruza's good form in Melbourne continued with a rampant 6-4 6-0 victory over Margarita Gasparyan in the first round on Tuesday.

Muguruza was runner-up at Melbourne Park last year, with the two-time grand slam winner looking for her first major success since 2017.

The Spanish star, who will face Ludmilla Samsonova in the second round, said she was reaping the benefits of a changed approach.

"I was for sure working very hard, and frustrated that the results weren't there for quite a few months. Sometimes you work hard, you want it so much, that doesn't help you," Muguruza said.

"It's hard to explain, but I felt like for a moment I was working hard, I was putting all the effort out there. The time that I had to go and compete, I wanted it too much. I was getting frustrated too early. At the end I couldn't let the racquet talk.

"I feel like now, after that experience, I managed to stay a little bit calmer and to just go and compete, probably have less expectations. I'm always, like, there and always so pumped. I'm just knowing myself a little bit better now, finding ways to compete and not let that energy and that desire, too much desire, get in the way probably."

It was a relatively good day for the top women's seeds, with Kenin – who conquered Muguruza in last year's final – winning through.

Ash Barty, Elina Svitolina, Karolina Pliskova and Belinda Bencic also advanced, while Victoria Azarenka's poor recent record in Melbourne continued.

KENIN ANNOYED DESPITE WIN

Kenin started her title defence with a 7-5 6-4 victory over Australian Maddison Inglis.

But while the American fourth seed mixed 23 winners with 27 unforced errors, Kenin said she felt her nerves as she defends a major crown for the first time.

"I was obviously quite annoyed the whole match. I felt like the first two points I started off well, then wasn't able to close out the first game. Obviously nerves happen," she said.

"She obviously played really well. She's a tricky opponent, tricky player. Yeah, it was quite hard on myself today, quite annoyed, as you said."

Kenin's next clash is a tough encounter against Kaia Kanepi, who brushed past Anastasija Sevastova 6-3 6-1.

BARTY, SVITOLINA AND PLISKOVA AMONG WINNERS

Barty made a spectacular start with a 6-0 6-0 thrashing of Danka Kovinic.

The world number one won the first 16 points and ended up losing just 10 for the match in an impressive start.

A two-time quarter-finalist at the Australian Open, Svitolina was tested but overcame Marie Bouzkova 6-3 7-6 (7-5) on Rod Laver Arena.

A huge challenge awaits Svitolina, who will next face Coco Gauff after the 16-year-old American beat Jil Teichmann 6-3 6-2.

Czech sixth seed Pliskova made quick work of Jasmine Paolini, wrapping up a 6-0 6-2 victory in just 47 minutes.

Bencic and Anett Kontaveit were among the other seeded winners.

NO EXCUSES FOR AZARENKA

A two-time Australian Open champion, Azarenka suffered a surprise 7-5 6-4 loss to Jessica Pegula in the first round.

The Belarusian's last win at the event came in 2016, having made first-round exits in 2019 and 2021 and missed the tournament in 2017, 2018 and 2020.

Azarenka was among the players forced to quarantine ahead of the major and while she said it played a part in her exit, she offered no excuses.

"Of course, it has impacted. Somebody who's coming out of hard quarantine and maybe has been able to adjust well, they'll go, 'Oh, maybe it hasn't impacted'. Somebody who lost early will say, 'Yeah, of course, it's impacted'. It would be hard to say," she said.

"Was that the best preparation for me? No. But try to sit here and find an excuse because of quarantine and this is just something that, as I said, it is what it is.

"I am disappointed that I wasn't able to perform that I knew I could. That's a bit hard to accept today because I knew I can play better, a lot better. At the same time I feel that I've tried everything I can to be able to be prepared, but unfortunately that hasn't worked out for me."

Greek 20th seed Maria Sakkari also bowed out after a loss to Kristina Mladenovic, while British 13th seed Johanna Konta retired injured while leading Kaja Juvan 6-4 0-2.
