After a quarter-final run at the 2019 Australian Open, a lot has changed for Ashleigh Barty but it is business as usual for the world number one in Melbourne.

Australian star Barty arrives at Melbourne Park for her home grand slam as the WTA Tour's top-ranked player and the reigning French Open and WTA Finals champion.

Barty became the first Australian to win the Roland Garros singles title since Margaret Court in 1973 and the first Australian to claim a major singles title since Sam Stosur's 2011 US Open triumph.

Her memorable 2019 exploits have heightened expectations in Melbourne, where all eyes are on the top seed ahead of her opening match against Lesia Tsurenko.

However, Barty's coach Craig Tyzzer told Omnisport: "There's more expectations on her, but she knows she has to go out there and compete every day, do her best. The result takes care of itself. If she's able to do that and keep focused on that stuff, she'll do some damage."

"The pre-season was pretty strong," Tyzzer said. "Ash put a lot of effort it. She's particularly fussy and a bit of a perfectionist anyway, so it kept her on edge a bit more knowing 'okay well I've got a responsibility here as well'.

"It's been good. We know what's coming but we will treat everything pretty much the same with regard to how we approach her matches."

"Slams are so hard to win over the two weeks, being healthy and playing well all the time," he continued. "Her expectations are that every match is going to be tough. She's pretty ready for the battle, and hopefully she can go deep into the tournament."

Barty is fresh off a 57-13 season on the WTA Tour – a year which yielded four titles from six finals in Miami, Paris, Birmingham and Shenzhen.

The 23-year-old claimed the biggest winner's cheque in tennis history after collecting $4.42million thanks to her WTA Finals victory over Elina Svitolina in November.

"I think her consistent level of play," Tyzzer said when asked about anything specific that helped Barty make such an impact last year. "There weren't many ups or downs. There weren't really super highs or big drop offs. I felt like over the 12 months her level was very consistent.

"There were a few times where she was tired after long periods of time. We could see that kind of stuff coming, so we controlled that fairly well with breaks and then build up again to the next tournament block. Her ability to play at a good level throughout the whole year was probably the biggest factor, I know there were other areas."

Barty's success saw Tyzzer – who has worked with the Queenslander since she returned to the sport in 2016 after a cricket stint – recognised as the WTA Coach of the Year.

But Tyzzer and countrywoman Barty are refusing to stand still in pursuit of further glory.

"There's certainly areas where she can get better. We've been working through the summer on her transitioning, try to get into the net more and get in behind her good shots. She sees it well in doubles but probably doesn't see it as well in singles yet. So that's probably one of the areas I'd like her to spend time on," he added.

"You can never sit still in the sport. If you sort of stop and feel like you've done everything and you're not going to improve then someone else is going to run over the top of you pretty quickly."

"We're doing a lot more work on her strength and speed, movement around the court," Tyzzer said. "Putting in a lot of time on returning, trying to make that better as well. As a coach, you're always looking for improvements, but you also have to acknowledge the good stuff and continue to encourage what she's done well. She's put good results together, so you don't want to make drastic changes just for the sake of changing.  You have to be careful with that stuff too."

The 108th edition of the Australian Open begins on Monday as the world's best tennis players battle it out at the first grand slam of 2020.

Novak Djokovic and Naomi Osaka will return to defend the titles they won last year, adding to the event's storied history.

The pair will face stiff competition from stacked fields in the men's and women's draw as a host of players seek glory in Melbourne.

To whet your appetite for the forthcoming feast of tennis, here is a selection of the best Opta facts related to the Australian Open.

 

- The last three years have seen the 12 women's grand slam tournaments being won by 10 different players; only Simona Halep and Osaka have won twice in that span.

- Djokovic won his seventh Australian Open title in 2019, the most of any male player in the history of the tournament. He has won the event every time he has reached the semi-finals.

- Of the last 14 editions of the Australian Open, 12 have been won by either Djokovic (7) or Roger Federer (5) – Rafael Nadal (2009) and Stan Wawrinka (2014) are the only other winners in that period.

- Victoria Azarenka (2012, 2013), Serena Williams (2009, 2010) and Jennifer Capriati (2001, 2002) are the only women to have won successive titles at the Australian Open since 2000.

- Federer won his sixth Australian Open title in 2018, 14 years after his first win at the event; no player has won multiple Australian Open titles over a longer period in the Open Era. It is his last win in a grand slam tournament to date.

- Since 2005 only Williams (2010, 2015) and Azarenka (2013) have won the title at the Australian Open as the number one ranked player in the world.

- Williams has not won any of the last 11 grand slams, with her last victory coming at the Australian Open in 2017 when she was pregnant – this is the American's longest span without a major title.

- Petra Kvitova lost in the final of the Australian Open last year, the only time she went further than the quarter-finals in her last 19 grand slam appearances, since winning Wimbledon in 2014.

- Either Nadal or Andy Murray has been the runner-up in nine of the last 10 Australian Open men's finals, Murray losing five times and Nadal four. Marin Cilic in 2018 is the only other player to lose an Australian Open final in that span.

- The last time an Australian made it to the men's final at the Australian Open was Lleyton Hewitt in 2005 and the last Australian to win the title was Mark Edmondson in 1976 (against fellow Australian John Newcombe).

Serena Williams' bid for a record-equalling 24th grand slam title begins at the Australian Open on Monday.

The American star will face teenager Anastasia Potapova in the opening round in Melbourne, where she is again among the favourites.

Williams is without a major title since the 2017 Australian Open, but appears well placed to end that wait.

We take a closer look at where Williams is at ahead of the first round.

 

Form and results

Williams did not need long to end another wait in 2020. The 38-year-old claimed the title at the Auckland Open for her first WTA Tour crown since 2017. And it was an impressive run in New Zealand, where she dropped just one set and also thrashed Amanda Anisimova 6-1 6-1 in a semi-final clash.

First up

Her first opponent, Potapova, is in vastly different form, having made a rather mixed start to 2020. The 18-year-old recorded wins in both Brisbane and Adelaide, but failed to qualify for the main draws. Potapova reached a career-high ranking of 64 last year and did beat Angelique Kerber at the French Open. Unsurprisingly, she has never met Williams, and would need a huge turnaround in form to cause a shock.

Draw

Williams should have some time to settle in. Tamara Zidansek or wildcard Han Na-lae potentially await in the second round, while Wang Qiang could be her opponent in the third.

What she said

"It's pretty satisfying just to get a win in the final [in Auckland]. That was really important for me – and I just want to build on it. It's just a step towards the next goal."

The Australian Open should be delayed or postponed if air quality deteriorates and smoke blankets Melbourne, according to Dr Matthew Conron. 

Australia has been ravaged by bushfires in recent months, triggering poor air conditions and concerns among players for their welfare ahead of the year's first grand slam.

Australian Open organisers have come under fire after allowing qualifiers to take place on Tuesday, despite a thick haze of smoke, forcing Slovenian Dalila Jakupovic to retire, while Eugenie Bouchard, Bernard Tomic and Maria Sharapova also struggled.

The main draw gets underway on Monday and all eyes are on the Victorian capital with conditions continuing to fluctuate.

Asked if the slam should go ahead, Conron - Associate Professor and Director of Respiratory and Sleep Medicine at St Vincent's Hospital in Melbourne - told Omnisport: "From a respiratory physician's point of view, if you had air quality of the type we have seen previously, I'd think the recommendation would be to delay or postpone the tournament until the weather cleared.

"I wouldn't think there'd be risk of long-term damage to your lungs. However, there's certainly a risk of precipitating an asthma attack. For those who have known asthma in particular, they'd be at a significant disadvantage to whose who haven't."

Conron, who helped prepare athletes for the 2008 Olympic Games in Beijing amid concerns over poor air quality in China, added: "Everyone would be at increased risk of developing respiratory symptoms.

"A lot would get sore throats, a bad and irritating cough and a smaller number would probably get asthma-type symptoms, particularly if they're not adequately controlled.

"If I was to provide advice to players and those wanting to do exercise in those conditions, if possible don't."

Tuesday's conditions were in the "very poor" range. For such weather, the Environment Protection Authority Victoria (EPA) recommends avoiding being outside and reducing prolonged or heavy physical activity. In some areas of Melbourne and Victoria, conditions were "hazardous". In those conditions, people are urged to close their windows and doors, while keeping physical activity levels as low as possible.

Conron added: "There's athletes who don't know they have asthma or might only have mild asthma and they're not on treatment. For that group of people, there's also the risk of increased symptoms associated with exposure to poor air quality. They might perform worse than they normally perform.

"The other thing is, tennis players are under the WADA [World Anti-Doping Agency] code. So you can't just treat them with steroids or high doses of inhalers without an adequate diagnosis, because they run the risk of being tested and face a ban.

"At the Australian Open, they would've had to notify WADA they are on medication. For example, if there's someone who doesn't know they have asthma and have an attack - you're allowed to take 16 puffs of Ventolin a day, which doesn't get you over the threshold. Not all inhalers are approved."

Dr Karl Kruszelnicki - who has degrees in physics and maths, biomedical engineering, medicine and surgery - also provided an insight into the conditions that have left tennis players concerned.

"I'd tell them not to do it [play]. The right thing to do would be to cancel the tournament," Kruszelnicki told Omnisport. 

"Sitting at rest, we breathe in maybe five litres of air every minute. But if we're exercising hard, we can get up to 50-70L. So you have these athletes on the court and they're shifting huge amounts of air in their lungs and they're getting acute affects from it. The air is not safe to breathe.

"Our immune system is made stronger by the moderate amount of exercise we do. But when you get to the top-grade athletes, their immune systems go to lunch and they're really fragile.

"These athletes at the tennis and Olympic Games, they're scared of people coming in with influenza. They are pushing their bodies way beyond what's actually healthy, but they want to win a tournament. In terms of the effect of the air pollution on them, they're more at risk than a less highly trained person, because their immune system has been knocked out of whack. 

"They have pushed themselves so hard but they have compromised their immune systems. So they're taking more pollutants in, but their bodies are more fragile. You think they have big muscles and can run around. In that regard they can, but almost certainly, they'd be more fragile. The technical term is an insult - an infection or pollution."

Ash Barty claimed her first title in her native Australia as she defeated Dayana Yastremska in the final of the Adelaide International.

The world number one will start her campaign to add her home grand slam to the French Open title she won in 2019 next week, and will do so in fine form after seeing off one of the most promising players on the WTA Tour.

Nineteen-year-old Yastremska was playing in her first WTA Premier final and it was Barty's experience that won the day in one hour and 26 minutes.

Having twice been a runner-up in the Sydney International, Barty laid those demons to rest with a 6-2 7-5 success that should give her plenty of confidence as she heads to Melbourne Park.

The first set was one dictated by Barty, as she used her nous to work the angles against Yastremska, playing a reigning world number one for the first time in her fledgling career.

Yastremska's unfamiliarity with such a situation was reflected by the 12 unforced errors she made in the first set.

By contrast Barty committed just one unforced error in the opener and was a constant threat to the Yastremska serve.

The Ukrainian's fifth service game saw her fend off three break points before Barty snatched a fourth to take a 1-0 lead in the second set, only to surrender her advantage with a series of errors.

Emboldened by the break back, Yastremska pressured the Barty serve again in the eighth game of the set, but the opportunity to earn a crucial second break was spurned.

Barty was ruthless in punishing Yastremska's profligacy, and won the final 10 points of the match to seal an eighth WTA singles title.

She will face another Ukrainian, Lesia Tsurenko, in the first round of the Australian Open, while Yastremska will be expected to have little trouble against fellow teenager Kaja Juvan.

Elena Rybakina continued her strong start to 2020 by winning the Hobart International title on Saturday.

The Kazakh, 20, proved too good for Zhang Shuai 7-6 (9-7) 6-3 to claim her second WTA Tour crown.

Rybakina is in impressive form to begin the year, having also reached the final in Shenzhen this month.

She delivered in the decider this time, converting all three break points she created on her way to victory in one hour, 33 minutes.

Rybakina will hope to carry her good form into the Australian Open, facing Bernarda Pera in the opening round.

Petra Kvitova admitted she was worried about the air quality in Melbourne ahead of the Australian Open, particularly as an asthma sufferer.

The year's first grand slam has been impacted by poor air quality in Victoria's capital after bushfires ravaged Australia in recent months.

Organisers have faced criticism during the qualifying rounds, although air quality has been rated as 'good' in Melbourne since Thursday.

Kvitova, who suffers from asthma, said the air was a concern heading into the grand slam.

"I've been a bit worried about it. Now I'm very happy that, as I mentioned, the sky, it's there again clearly," last year's runner-up told a news conference on Saturday.

"Of course everybody knows that I do have asthma problems, which I wasn't really happy about that if the air is still bad.

"It's same for everybody, so it will be really difficult to breathe for sure. I do have my medicines here, as well.

"Yeah, I'm going to use it if it's important."

However, Kvitova – who faces fellow Czech Katerina Siniakova in the first round – backed officials.

"Well, I'm very comfortable with everything they've taken," she said.

Naomi Osaka believes she is not as fearless as last year as she prepares for her Australian Open title defence.

The Japanese star claimed her second grand slam title in Melbourne in 2019, backing up her US Open success from just months prior.

But the 22-year-old, seemingly more aware of what was at stake, said she felt more fearless last year.

"I feel like last year I was young. Last year I feel like I was young. I was just this young kid that was going out. My goal was to win, and I wasn't going to let anything stop me," Osaka told a news conference on Saturday.

"I feel like now I appreciate more every single win because I know what it took to get it.

"Of course, I want to win every match and I want to go out there and do that. That's what I'm here for.

"I think maybe last year I was a little bit more fearless."

Osaka, the world number three, is again among the favourites and faces Marie Bouzkova in her first-round match.

Ashleigh Barty, the world's top-ranked player, is also expected to challenge and Osaka praised the Australian while talking down suggestions of a rivalry with a player she has met three times since the start of 2018.

"It's super weird. People keep asking me questions like we're rivals or something. She's in the finals of Adelaide right now," she said.

"I think obviously she's a great player. She's the number one ranked player in the world. I don't know, we've played really close matches."

Caroline Wozniacki insisted she was calm and just enjoying herself ahead of her final professional tournament at the Australian Open.

Wozniacki will retire after the Australian Open, which begins on Monday, ending a career that saw her win the title in Melbourne in 2018 and hold the top ranking.

The Dane, 29, said she was staying calm so far, but expects there to be emotion once her career is officially over.

"It's not a situation that I've ever been in. It's hard to tell," Wozniacki told a news conference on Saturday when asked if she would stay calm.

"So far I'm calm and just enjoying myself. I have my family here, which is great. I'm sure once the last ball is hit, it's going to be a bit emotional."

Wozniacki will face Kristie Ahn in the opening round in Melbourne, but said her approach had remained unchanged despite the circumstances.

"So far I've just approached it like any other tournament, but obviously it's different since it's my last one," she said.

"I'm just enjoying being out there. I've had some great practice sessions. I've done everything I could to prepare as well as I can for this tournament, then hope for the best."

Ash Barty produced a superb comeback to reach the final of the Adelaide International, where she will face Dayana Yastremska in an enticing clash before she bids to win the Australian Open.

The world number one was forced to come through a testing last-four encounter with American Danielle Collins but got a victory that ensures she will remain top of the rankings after the first major of 2020.

Her power posed Barty plenty of problems and another shock appeared on the cards when Collins, who defeated Sofia Kenin and Belinda Bencic en route to the semis, claimed the first set.

Collins struggled on serve in the second set, however, and Barty was ruthless in capitalising as she raced into a 5-0 lead.

Powerless to prevent Barty forcing a decider, Collins demonstrated admirable resilience in the third set.

Barty broke for a 4-3 lead with a return winner, but Collins' vicious backhand saw her hit straight back.

The same shot proved her downfall in the decisive tie-break, though, a backhand error securing the match for Barty, who will turn her attention to one of the WTA Tour's rising stars in Yastremska.

Ranked 24th in the world, the 19-year-old overcame world number 12 Aryna Sabalenka, adding the Belarusian to a list of scalps that has this week also included Angelique Kerber.

Sabalenka saw off Simona Halep in the quarter-finals but Yastremska had too much for her as the Ukrainian completed a 6-4 7-6 (7-4) success.

"Especially in the beginning of the year, I think it brings me some confidence before the grand slam, so it's nice to be in the finals," Yastremska said after reaching her first WTA Premier final.

"Here I started really to feel, with each game, that I'm playing better and better."

Meanwhile, at the Hobart International, Zhang Shuai overcame Veronika Kudermetova to set up a final with Elena Rybakina, who beat 2015 champion Heather Watson.

Angelique Kerber is hopeful over her fitness for the Australian Open as she deals with a hamstring injury.

Kerber retired during her second-round match against Dayana Yastremska at the Adelaide International on Wednesday.

The 2016 Australian Open champion, who will face a qualifier in the first round, said she was hopeful ahead of the tournament starting on Monday.

"I'm trusting my team and I mean of course it was not the way I would like to play in Adelaide and finish the tournament before Melbourne," Kerber told a news conference on Friday.

"But I know right now what it is, I'm also in touch with my medical team in Germany and here with my team so I'm hopeful and I'm thinking that it will be fine when I start the tournament."

Kerber revealed she dealt with a similar left-hamstring injury late last year and knows how to cope with the issue.

"I had it before at the end of last year so I know a little bit what it is and we know what we have to do and how to treat that," she said.

"That's actually a good sign that everybody knows how to take care of it."

Venus Williams' clash with Coco Gauff headlines the Australian Open first round, but former champion Stan Wawrinka also faces an early test in Melbourne.

Williams and Gauff will meet for the second time in what is a blockbuster opening-round encounter.

But there are several intriguing clashes in the first round at the year's first grand slam and we take a look at six of the best.

 

Damir Dzumhur v Stan Wawrinka [15]

Wawrinka would have preferred a friendlier draw than a man he has lost to in two of their three meetings. The Swiss 2014 champion was resurgent last year, while Dzumhur has been unable to replicate the form of his breakout season in 2017. Still, the Bosnian beat Wawrinka in three sets on clay in Geneva last year so the three-time grand slam champion will have to be near his best.

Daniil Medvedev [4] v Frances Tiafoe

Tiafoe thrilled during a run to the quarter-finals in Melbourne last year, but that would prove to be the high point of his 2019. The American has made a slow start to 2020 with first-round losses in Doha and Auckland, but was competitive against Medvedev in a 6-2 7-5 loss in Washington last year. After a spectacular 2019 that included reaching the US Open final, Medvedev shapes as the most likely to stop the 'Big Three', although he will need to get through a somewhat tricky opener first.

Sam Querrey v Borna Coric [25]

While he has dropped off since 2017, Querrey will fancy his chances against Coric after the Croatian's difficult finish to last year. Coric finished 2019 with six straight losses and suffered two more at the ATP Cup, to go with a win over Dominic Thiem. After four consecutive first-round exits in Melbourne, Coric reached the fourth round last year, while Querrey has never been beyond the third round in Melbourne. Coric won their only previous meeting at the French Open in 2015.

Venus Williams v Coco Gauff

Arguably the pick of any first-round match, the 39-year-old Williams meets the 15-year-old Gauff once more. Gauff stunned Williams 6-4 6-4 at Wimbledon last year and her ranking then (313) compared to now (66) tells the story of how she finished 2019 as the teenager followed it up with a title win in Linz. Williams withdrew from Brisbane due to injury, making this a hugely tough task for the seven-time grand slam singles champion.

Kristina Mladenovic v Karolina Pliskova [2]

Pliskova has enjoyed Melbourne in recent years, reaching at least the quarter-finals in each of the past three, but was handed a tough start in 2020. The Czech is coming off a title win in Brisbane and that will give her much-needed confidence ahead of facing former world number 10 Mladenovic. The pair have split their previous four meetings, with Mladenovic winning the last of those in 2017.

Donna Vekic [19] v Maria Sharapova

A wildcard, Sharapova was always going to be the danger in the draw – and she landed alongside 19th seed Vekic. Vekic enjoyed a fine 2019 to rise into the world's top 20, while Sharapova battled injuries and has fallen to 145th in the rankings. Vekic should be the favourite to advance, but if five-time major winner Sharapova can find some form, the Russian is always a threat and last bowed out in the opening round in Melbourne in 2010.

Garbine Muguruza hopes to be fit for the Australian Open after withdrawing from the Hobart International due to a viral illness.

Former world number one Muguruza withdrew from her quarter-final against Veronika Kudermetova on Thursday.

The two-time grand slam winner is scheduled to face a qualifier in the first round of the Australian Open on Tuesday. She is in the same quarter of the draw as Karolina Pliskova, Elina Svitolina and Angelique Kerber.

Muguruza tweeted: "I'm sorry I could not play today. I've had a fever for several days and this morning my body said 'enough'.

"I'll rest today and hope to travel to Melbourne tomorrow. I hope to be able to play [the Australian Open].

"I want to thank all the fans in Hobart for their support and love. I hope to return soon."

Heather Watson beat top seed Elise Mertens 6-7 (5-7) 6-4 7-5 to reach the semi-finals, while Kudermetova will take on Zhang Shuai.

At the Adelaide international Simona Halep suffered a 6-3 6-2 quarter-final loss to Aryna Sabalenka.

Second seed Halep lasted just one hour and nine minutes against Sabalenka, who reeled off seven straight games to take the first set and move 5-0 up in the second.

The Wimbledon champion won the next two games but was unable to hold serve to stay in the match.

Sabalenka will take on Dayana Yastremska, who beat Donna Vekic 6-4 6-3, in the semi-finals.

Top seed Ash Barty repeated her French Open final victory over Marketa Vondrousova to reach the final four in Adelaide.

Barty hit 20 winners and saved six of seven break points to secure a 6-3 6-3 triumph and advance to a meeting with Danielle Collins after the American overcame Belinda Bencic 6-3 6-1.

Liam Broady hit out at the ATP and Australian Open for sending an email which he described as a "slap in the face" regarding conditions in Melbourne.

Qualifying has been impacted at the year's first grand slam due to poor air quality, with organisers facing criticism for letting play go ahead despite the conditions.

Slovenian Dalila Jakupovic retired during her match due to breathing difficulties, with the air quality in Melbourne in the 'very poor' range on Tuesday as smoke from bushfires in Australia cause havoc.

Broady, who was beaten in qualifying on the same day, hit out at organisers amid concerns over player welfare.

"The more I think about the conditions we played in a few days ago the more it boils my blood. We can't let this slide," the Brit wrote in a message posted on Twitter.

"The email we received yesterday from the ATP and AO was a slap in the face, conditions were 'playable'. Were they 'healthy'? Citizens of Melbourne were warned to keep their animals indoors the day I played qualifying, and yet we were expected to go outside for high intensity physical competition?

"What do we have to do to create a players union? Where is the protection for players, both male and female? When multiple players need asthma spray on court and they don't even have asthma? When a player collapses and has to retire due to respiratory issues?

"On tour we let so many things go that aren't right but at some point we have to make a stand. ALL players need protection not just a select few."

Conditions in Melbourne improved on Wednesday, although 'moderate to poor' air quality was forecast for Thursday.

Three-time grand slam winner Angelique Kerber suffered a back injury that forced her to withdraw from the Adelaide International on Wednesday with the Australian Open just around the corner.

Kerber, who won the Australian Open in 2016, had lost the first set to Dayana Yastremska 6-3 and was a break down in the second when she required on-court medical assistance.

After being put through a series of stretches, the former world number one decided she was unable to carry on and retired, allowing Yastremska to reach the last eight of the competition, where she will meet Donna Vekic after her 2-6 7-5 6-1 win over Maria Sakkari.

The most impressive win of the day belonged to Marketa Vondrousova, however, as last year's French Open runner-up claimed a stunning 6-0 6-0 victory over home hope Arina Rodionova, setting up a meeting with another Aussie in the quarters – world number one Ash Barty.

Vondrousova, 20, is taking part in her first tournament since Wimbledon after undergoing wrist surgery in September and will be out for revenge against Barty, who beat her at Roland Garros in June.

Fourth seed Belinda Bencic came through a tight tussle with Julia Goerges to emerge a 7-6 (8-6) 7-6 (7-4) victor, with her last-eight opponent Danielle Collins having significantly less difficulty against fellow American Sofia Kenin – the unseeded 26-year-old winning 6-3 6-1.

The fourth quarter-final will see Aryna Sabalenka go head-to-head with Simona Halep, after the Belarussian sixth seed eliminated Bernarda Pera 7-6 (7-4) 6-2.

Elise Mertens remains on course for a third Hobart International title after the top seed dropped single game in her 6-1 6-0 defeat of Viktoria Kuzmova, setting up a quarter-final with Great Britain's Heather Watson, a 7-6 (7-5) 6-3 winner against Fiona Ferro.

Aussie wildcard Lizette Cabrera claimed a 4-6 6-4 6-4 upset over Kristyna Pliskova, while second seed Garbine Muguruza edged past Ons Jabeur 3-6 6-3 7-6 (7-4) and will face Veronika Kudermetova.

Shuai Zhang, Lauren Davis and Elena Rybakina are also into the quarter-finals following respective triumphs over Kateryna Kozlova, Magda Linette and Alize Cornet on Wednesday.
