Emma Raducanu is calling on the advice of England men's football captain Harry Kane as she seeks a deep run at the Australian Open.

Raducanu shot to stardom in 2021 when she became the youngest woman to win the US Open.

However, the 20-year-old heads to Melbourne ranked 77th in the world by the WTA, having only reached one semi-final – at the Korea Open in September – since her triumph at Flushing Meadows.

Raducanu has been nursing an ankle injury prior to the season's first grand slam, but that problem has now cleared up, and she revealed Tottenham star Kane has been offering his advice.

"Harry's obviously such a great role model and very professional and I think to be able to speak to him is really cool," Raducanu told the media. 

"We haven't spoken so much but he's obviously an outstanding player, and it's just pretty cool isn't it?

"For someone of his achievements, it's pretty remarkable how he’s so humble. I respect him a lot.

"It's obviously really cool to speak to some other athletes. I think it's good because we all kind of understand what each other are thinking and going through at times.

"And at the end of the day they're just really cool people as well."

Raducanu will face Tamara Korpatsch in her first match in Melbourne on Monday.

The Professional Tennis Players Association is committed to equal pay for men and women at grand slam level, according to the man who teamed up with Novak Djokovic to launch the organisation.

Vasek Pospisil, whose on-court doubles efforts helped Canada win the Davis Cup for the first time in November, said the PTPA would "fight for both sides" in its efforts to improve players' prospects throughout the sport.

The breakaway union has caused controversy, with the ATP and WTA, which run the men's and women's tours, adamant they already have significant player representation when it comes to making decisions in the best interests of tennis.

Djokovic quit as president of the ATP player council to become the figurehead of the PTPA, which was launched at the height of the pandemic during the 2020 US Open.

There was initial criticism of the PTPA when no women appeared to be involved.

However, Pospisil said at the time discussions were ongoing, and ahead of the upcoming Australian Open, its first executive committee was unveiled, consisting of four men and four women.

Joining Djokovic and Pospisil are Hubert Hurkacz and John Isner, plus WTA players Paula Badosa, Ons Jabeur, Bethanie Mattek-Sands and Zheng Saisai.

Pay has been equal at all the grand slams since 2007, when Wimbledon announced it would reward women the same amount it pays men.

Asked about equal pay at the four majors and the PTPA's position, Pospisil told Stats Perform: "From day one, we always knew that this would only be successful with the women, and that has always been our goal. And so we're really happy that we're gaining a lot of traction now on the women's side.

"Currently, there is equal pay at the grand slam level, I believe, so that's obviously amazing.

"It is a joint organisation, both men and women, and we'll do everything to fight for both sides.

"Obviously, they're separate tours. The WTA, ATP, and grand slams are joined, of course. So, the staff will have their hands full with trying to advocate for both sides.

"It's a unified player association for both men and women, and we're really proud of that and where we're going."

Those already involved, and those the PTPA will hope to attract, are being advised the union is aiming to bolster the rights – and at the bottom line, the earning potential – of all involved.

There is currently significantly more money on offer on the ATP tour than on the WTA circuit, which points to issues of inequality remaining in the sport.

It has been known in recent times for some high-profile tournaments, where tours converge, to pay its men's champion more than its title-winning woman. This is despite events on both tours being best-of-three-set matches, whereas in the slams women play best-of-three and men play best-of-five, a matter that has long been a trigger for equal-pay debate.

Pospisil believes the WTA has a "smart and passionate" group of eight on its ExCo and said the "energy was amazing" when the group met for dinner on Thursday in Melbourne.

"I just have such a good feeling after a few years of working on this," Pospisil said. "To finally be at the stage where we're ready to go, are launching, got everything we need, and we have amazing player board reps that honestly we couldn't be happier with."

Djokovic, a 21-time singles grand slam winner, is at the forefront, and Pospisil said the 35-year-old Serbian's role has been crucial.

"I feel like you need somebody that is at the top of the sport," Pospisil said. "So, I just think all the players and our organisation, we're very lucky that he's so supportive and that he's stuck his neck out and is fighting for what he believes in and what he believes is right."

Iga Swiatek had a reminder of the stellar rivalry that never was when she practised alongside Ash Barty on Saturday ahead of the Australian Open.

Australian Barty is the reigning women's singles champion at Melbourne Park, but she retired just weeks after lifting the trophy last year.

That shock decision from the then 25-year-old saw a figurehead of the WTA Tour make way, and Swiatek has taken her place as the undisputed world number one, saying Barty has inspired her to hit those heights.

The prospect of Barty and an ever-improving Swiatek fighting for the tour's biggest titles was dashed, and they only ever played twice, with Barty winning both times.

Barty announced on January 6 she is pregnant, and she appears to have no inclination to perform a retirement U-turn.

"For sure, when she retired, I felt like she still had the best tennis out there," Swiatek said after their light-hearted court session.

"So, I was pretty sad that I'm not going to be able to compete against her and maybe win.

"But on the other hand, she gave me a lot in terms of my motivation and my kind of willingness to practise even more and to have more variety on court.

"When I played against her, I felt like she just has all these different game styles and slice. Even in her book, she says she has five types of slice. I don't know how that's possible. I still haven't figured out only one type.

"I have huge respect for Ash. She really gave me huge motivation at the beginning of last season to get even better. I'm kind of grateful for that."

Swiatek will play the first night session match on Rod Laver Arena at this year's championships, taking on a familiar foe in Germany's Jule Niemeier.

At the US Open last September, the heavy-hitting Niemeier led by a set and a break against Swiatek in the fourth round, only to let the Pole back in and eventually surrender the third set 6-0. Swiatek went on to win the title, her third grand slam trophy success.

Niemeier also reached the Wimbledon quarter-finals, and Swiatek is wary of the opening test that awaits.

"We played at the US Open, and you saw how intense that match was, how tough," Swiatek said. "It's not going to be easy.

"But on the other hand, any match in a grand slam is always more intense and more stressful than other tournaments. I'll be ready for it.

"It's nice also that we played not so long ago, so I can take a lot from that match. Now I know how her ball feels on the racket. So, we'll see. But she has the same."

Emma Raducanu is "in a good place" ahead of the Australian Open after an ankle injury threatened her participation.

Raducanu was left in tears after retiring against Viktoria Kuzmova in their round-of-16 match at the ASB Classic.

The 20-year-old won the first set 6-0, but after losing the second set 7-5, Raducanu was unable to continue, sparking fears over her ability to play in the Australian Open in just 11 days.

But with her tournament opener against Tamara Korpatsch now just two days away, the 2021 US Open champion eased fears over her fitness, saying she "fully trusts" her ankle.

"I've been able to do preparation, albeit more limited than usual," Raducanu told reporters on Saturday. "But I'm feeling in a good place to go out there and give it my best shot.

"We were thrown a bit of a curveball but we remained optimistic. It's been a team effort to get me to this place. We've been building it up pretty gradually.

"For the ankle, I feel really good. It's going to be more introducing certain things, and the rate at which we've had to do it has been really quick.

"But I've not really played much tennis ever in my career, so I'm kind of used to it. And I'm not stressed about lack of tennis that much."

In Melbourne, Raducanu will be aiming to go beyond the second round of a grand slam for the first time since her incredible US Open heroics in 2021.

Iga Swiatek starts the Australian Open as almost as strong a favourite to win the women's singles as Novak Djokovic is for the men's event.

Considering Djokovic is a nine-time champion in Melbourne, and Swiatek has never reached the final, that is some going and indicative of the Polish player's dominance on the WTA Tour over the last 11 months.

Swiatek ended last year with eight titles to her name, winning the French Open and US Open among them, and the 21-year-old has accrued more than twice as many ranking points as the next player on the WTA list, Ons Jabeur.

Her ascent to become the dominant woman in tennis has been remarkable, and Swiatek has also earned admiration for her efforts to raise funds for children in war-hit Ukraine.

But is she such an outstanding favourite for the Melbourne Park title as the odds-makers have it?

Since the US Open, she has been a champion at just one – modest by her standards – of the four tournaments she has contested, including the United Cup team event.

Here, Stats Perform looks at five others who might have a say in the destination of the year's first major.

Jessica Pegula

Swiatek was reduced to tears after a 6-2 6-2 drubbing by Pegula on January 6 at the United Cup, her first loss of the year.

She later described Pegula's performance as "the perfect match", and will hope the American cannot always rise to that level.

"It's always hard when you lose, especially when you're playing for the team and your country," Swiatek said at the time, explaining her post-match tears.

Swiatek had won all four of the matches they contested in 2022, dropping only one set, with quarter-final wins on the way to her two grand slam triumphs included in that set.

The result in Sydney, therefore, might have been just a blip, but Pegula is number three in the world for a reason, and Swiatek will surely want to avoid her over the coming fortnight.

Coco Gauff

Is now Gauff's time? There's a question that has been buzzing around the tennis circuit for at least a couple of seasons, despite the American being just 18 years old.

Time, it should be clear, is firmly on her side. She soared to fourth in the rankings in October but has slipped a little since, while remaining firmly established in the top 10.

Given her great talent, Gauff should be resident in the top 10 for many years to come, so we can afford to wait before watching her fly. The sometimes-erratic forehand remains in need of fine-tuning, and Gauff began this year with just two career singles titles to her name after missing out on a trophy in the 2022 season.

However, she reached a first grand slam final last June, losing to Swiatek in Paris, and began 2023 by capturing a title in Auckland where, as top seed, she made light work of the field.

The victory made her the sixth American player to secure three or more WTA-level titles before turning 19 in the last 40 years, after slam winners Monica Seles, Jennifer Capriati, Lindsay Davenport, Venus and Serena Williams.

That is some company for Gauff, who will face Katerina Siniakova in the first rout in Melbourne, to be keeping, and her time will come. It might even come in Melbourne.

Ons Jabeur

After finishing runner-up to Elena Rybakina at Wimbledon and Swiatek at the US Open, Jabeur is targeting a third successive slam final.

The Tunisian would win most popularity contests on the Tour, but she wants one of the big trophies now, and has to be seen as a strong contender in Australia.

Her preparations took a knock with a loss to 18-year-old Czech Linda Noskova at Adelaide International 1, but that will only have made Jabeur work harder in the build-up to the major.

She was gutted to have to pull out of the Australian Open with a back injury last year, and a first-round loss at the French Open followed, but Jabeur came good at the next two majors, albeit falling at the final hurdle.

Aryna Sabalenka

At this time last year, Sabalenka was in crisis, her serve a massive weakness as she struggled to deliver the ball safely.

She recovered from going a set down in three consecutive matches at the Australian Open before losing a rollicking tussle in round four with Estonian veteran and upset specialist Kaia Kanepi.

Sabalenka served a wretched 15 double faults in that match, which was sadly more or less par for her in the early stages of the 2022 season, but the Belarusian got her act together, overcome those yips, and finished the year strongly.

A semi-final run at the US Open was followed by an appearance in the WTA Finals title match, where she lost a close encounter with Caroline Garcia.

Sabalenka began this year not with the serving jitters, but with the Adelaide International 1 title, not dropping a set all week.

She has a big game and with it growing confidence. At the age of 24, she should be entering her prime years, and 2023 could be a special 12 months for the woman with the tiger tattoo.

Zheng Qinwen

The WTA's 2022 Newcomer of the Year winner, Zheng is a 20-year-old Chinese player who could soon follow in the footsteps of compatriot Li Na and begin scooping the biggest prizes in tennis.

How soon? Well, probably not quite yet, but then again very few picked out the then 54th-ranked Swiatek to win the 2020 French Open, the moment that launched her to stardom.

Zheng has rocketed to 30th in the rankings, having begun last year at 126th on the WTA list, and should be considered capable of halving her ranking over this season.

She first came to major prominence at the French Open, when she defeated Simona Halep and for a while also had Swiatek's number in their fourth-round match, winning the first set before menstrual cramps and a leg problem caused her to lose momentum.

The WTA Tour is a learning curve and slam-level success might not come immediately for Zheng, but that newcomer award came her way because she is a player shaping up to have a big say in the sport's future. Along with the likes of Gauff and Swiatek, she could still be a big factor in a decade's time.

Belinda Bencic eased to a 6-0 6-2 final victory over Daria Kasatkina to claim the Adelaide International 2 crown on Saturday.

Both Bencic and Kasatkina did not have to play a semi-final after their respective opponents, Veronika Kudermetova and Paula Badosa, both pulled out with injuries.

Bencic romped to victory in the final though, dropping just two games against her Russian opponent to lift her first title in Australia.

The match lasted just 67 minutes, as the 2021 runner-up converted five of her seven break point opportunities while not facing a single break point herself.

Bencic rattled off eight games in a row to start the final, and though Kasatkina did save some face with a couple of holds late on, the world number 13 finished the job to win in straight sets ahead of the start of the Australian Open next week.

"I'm happy I could show my work here on the court," Bencic told reporters at a post-match news conference. "I thought I played some great matches from the start of the tournament and also against different kind of opponents so I really could test myself out there in every way and just go confidently into the Australian Open."

At the Hobart International, Lauren Davis ended a six-year title drought with a 7-6 (7-0) 6-2 triumph over Elisabetta Cocciaretto in an all-unseeded final.

In the opening set, every game went to serve until the tie-break, when Davis found three crucial breaks to take the advantage heading into the second stanza.

But the second set was not the same tight affair as Cocciaretto, playing in her first Tour-level singles final, collapsed to a 5-0 deficit to leave her staring down the barrel of defeat.

Davis, who herself was playing in a first Tour-level final since winning the trophy in Auckland in 2017, overcame losing the next two games to take the title having not lost a set at the tournament.

Davis was delighted after the match, saying: "I have a lot of emotions going through my body right now. I'm just really happy, really excited. I really had to play my best in order to win today."

Iga Swiatek has no interest in what people expect from her and the world number one will not be "living in the past" as she targets more success this season.

Swiatek was in a class of her own last year, winning a staggering eight titles to firmly establish herself as the best player in the world.

A second French Open title and a maiden US Open triumph were the highlights for the 21-year-old in a stellar 2022.

The Pole will start her quest to win the Australian Open with a first-round match against Germany's Jule Niemeier at Rod Laver Arena on Monday.

Swiatek is the favourite to be crowned champion at Melbourne Park, but will not be putting too much pressure on herself.

"When I don't care about what people think and what their expectations of me are, it's easier for me to succeed," Swiatek told BBC Sport.

"That was what I tried my best to do in 2022.

"Although I'm proud of them, I'm not going to try to match my previous achievements because it would not be constructive.

"A season like that is something amazing and rare. Sure, I would love to do it again, but it's not advantageous to live in the past."

Swiatek was beaten by Danielle Collins at the semi-final stage of the Australian Open 12 months ago.

Belinda Bencic will play Daria Kasatkina in the final of the Adelaide International 2, though neither of them had to play a semi-final.

Bencic was due to go up against Veronika Kudermetova in the second scheduled semi-final on Friday, only for the Russian to withdraw due to a hip injury.

It was a similar story for Kasatkina, who received a walkover after Paula Badosa pulled out of their match, citing a thigh problem.

While Bencic and Kasatkina will now get the chance to claim a trophy early in the season, the focus for Badosa and Kudermetova will be on regaining fitness in time for the Australian Open, which starts next week.

Badosa was confident she can recover for the upcoming major, where she has been drawn against American Caty McNally in the first round.

"I'm really disappointed that I had to withdraw because I was really looking forward to the match," Badosa told reporters.

"When I was playing [against Beatriz Haddad Maia], it was a very tough match, especially physical, so I felt a little bit in my abductor. I felt like I pulled it a little bit.

"I feel a little bit worse, so I have the Australian Open ahead, and I hope I can recover for that."

Badosa needed two hours and 35 minutes to get past the Brazilian on Thursday, having knocked off Anett Kontaveit and Kaia Kanepi in the earlier rounds.

"I played three really good matches," the Spaniard said. "I think that helps me, as well, on my confidence for the tournaments ahead. Now it's something that I cannot control, so it is what it is."

At the Hobart International, Elisabetta Cocciaretto set up a showdown with Lauren Davis.

Sofia Kenin, the 2019 champion, fell 7-5 4-6 6-1 to world number 67 Cocciaretto, who has reached her first Tour-level singles final.

"It’s unbelievable for me to be here in the final of such a great tournament, and I’m really happy about my performance," Cocciaretto said.

"[Kenin is] a very good player, I was a junior when she won the grand slam [2020 Australian Open], so for me it's an honour to play against her."

Davis, meanwhile, saw off Anna Blinkova in straight sets. She has not featured in a Tour-level final since clinching the trophy in Auckland in 2016.

Veronika Kudermetova saved five match points as she beat Danielle Collins to reach the Adelaide International 2 semi-finals before Belinda Bencic knocked Caroline Garcia out.

Sixth seed Kudermetova showed great defiance to defeat American Collins 4-6 7-6 (7-5) 6-1 on Thursday.

Kudermetova fended off five match points when serving to stay in the tournament at 6-5 down in the second set and duly forced a tie-break.

Collins, runner-up to Ash Barty in the Australian Open final last year, took a 3-0 lead in the breaker, but back came her Russian opponent to level the match.

The world number nine dominated the deciding set to seal a meeting with Bencic in the last four.

Eighth seed Bencic got the better of WTA Finals champion Garcia 6-2 3-6 6-4.

Garcia broke straight back after going 3-1 down in the final set, but Bencic broke for the fourth time in the match to go through.

Paula Badosa and Daria Kasatkina will contest the other semi-final after beating Beatriz Haddad Maia and Petra Kvitova respectively. 

Elisabetta Cocciaretto saved two match points as she came from a set down to beat Bernarda Pera 5-7 7-6 (10-8) 6-4 in the quarter-finals of the Hobart International. 

The 21-year-old Italian will now face 2020 Australian Open champion Sofia Kenin, who also stormed back to defeat Anhelina Kalinina 4-6 6-3 6-1.

Lauren Davis and Anna Blinkova will do battle in the other semi-final following wins over Wang Xinyu and Yulia Putintseva respectively. 

Nine-time champion Novak Djokovic will make his return to the Australian Open against Spain's world number 75 Roberto Carballes Baena.

After being deported from Australia last year amid a row over his refusal of a COVID-19 vaccination, Djokovic is firmly back in favour and chasing history in Melbourne, with a record-equalling 22nd men's singles grand slam in his sights.

He begins against an opponent who in four previous main draw appearances has only ever won one singles match at Melbourne Park.

Defending champion Rafael Nadal, whose 22 slam titles Djokovic is seeking to match, has a tricky opener against rising British star Jack Draper, the world number 40.

Second seed Casper Ruud will tackle Czech Tomas Machac first up, with the 115th-ranked player unlikely to prove too daunting an obstacle for last season's French Open and US Open runner-up.

Fifth seed Andrey Rublev could face an awkward assignment against wildcard and former US Open winner Dominic Thiem, while Australia's Nick Kyrgios begins against Russian Roman Safiullin.

Neither 13th seed Matteo Berrettini nor five-time runner-up Andy Murray would have been delighted to be paired together, but that is what happened in Thursday's draw.

In the women's singles, top seed Iga Swiatek starts her bid for a first Australian Open title against Germany's Jule Niemeier, who caught the eye last year on a run to the Wimbledon quarter-finals.

American seventh seed Coco Gauff starts against Czech Katerina Siniakova, while Jessica Pegula, Gauff's third-seeded compatriot who recently beat Swiatek in the United Cup, will face Belgian Jaqueline Cristian.

Gauff could face former US Open winner Emma Raducanu in the second round. Unseeded Briton Raducanu starts against Germany's Tamara Korpatsch.

Former champions Sofia Kenin and Victoria Azarenka go head to head in the first round, with American Kenin unseeded this year and Belarusian Azarenka the 24th seed.

Azarenka's compatriot Aryna Sabalenka is fancied to do well, having banished last year's serving yips, and the fifth seed starts against Czech Tereza Martincova.

Tunisian second seed Ons Jabeur, runner-up at Wimbledon and the US Open, begins her latest quest for an elusive grand slam title against Slovenian world number 88 Tamara Zidansek.

Former US Open winner Bianca Andreescu is unseeded in Australia and Czech 25th seed Marie Bouzkova drew a possible short straw by getting the Canadian in round one.

Four-time grand slam champion Naomi Osaka has announced she is pregnant and is not expecting to play tennis again until next year.

The 25-year-old has not been in action since September and withdrew from the upcoming Australian Open on Sunday, but no reason was given for her prolonged absence.

However, Osaka revealed on her personal social media accounts on Wednesday that she is expecting her first child and will take a year out.

"Can't wait to get back on the court, but here's a little life update for 2023," she wrote alongside an image of an ultrasound. 

"The past few years have been interesting to say the least, but I find that it's the most challenging times in life that may be the most fun. 

"These few months away from the sport have really given me a new love and appreciation for the game I've dedicated my life to.

"I realise that life is so short and I don't take any moments for granted, every day is a new blessing and adventure. 

"I know that I have so much to look forward to in the future, one thing I'm looking forward to is for my kid to watch one of my matches and tell someone, 'that's my mom,' haha.

"2023 will be a year that'll be full of lessons for me, and I hope I'll see you guys at the start of the next one 'cause I'll be at Aus 2024. Love you all infinitely."

The Japanese former world number one won the Australian Open in 2019 and 2021, while also winning the US Open in 2018 and 2020.

Osaka is currently ranked 42nd in the world and has been replaced by Dayana Yastremska in the main draw for the opening grand slam of the year.

"I don't think there's a perfectly correct path to take in life," Osaka added in her post. "But I always felt if you move forward with good intentions you'll find your way eventually."

Danielle Collins needed seven match points to defeat Jil Teichmann at the Adelaide International 2 but ultimately progressed to the quarters.

Collins, seeded 10th, had victory in her grasp after reeling off four straight games in the second set.

Yet she was unable to get over the line at the first six times of asking, initially failing to serve out the win before Teichmann saved five match points.

Collins, though, regained momentum in the tie-break to win 6-3 7-6 (7-2).

World number nine Veronika Kudermetova is next up for Collins, having received a walkover to the last eight.

Caroline Garcia, the highest-ranked player left in the tournament, overcame Katerina Siniakova 6-3 3-6 7-5, but was made to work for her win.

Having been pegged back in the second set, Garcia seemed well set to push for victory when she went 3-1 up in the decider, but Siniakova broke and then held her serve to restore parity.

A tie-break looked likely until Garcia converted the third break point of a thrilling 12th game to claim victory.

Barbora Krejcikova, the 2021 French Open champion, was ousted by fifth seed Daria Kasatkina, who cruised through 6-2 7-5.

World number eight Kasatkina will take on two-time Wimbledon champion Petra Kvitova for a place in the last four.

Belinda Bencic also progressed, as did Paula Badosa and Beatriz Haddad Maia.

Anna Blinkova caused an upset at the Hobart International, dispatching top seed Marie Bouzkova 7-5 6-4.

Fifth seed Anhelina Kalinina is the favourite after Bouzkova's exit and a tie with 2019 champion Sofia Kenin is her reward for a win over Tatjana Maria. 

Paula Badosa savoured a strong serving day as she overcame Anett Kontaveit in a tricky Adelaide International 2 opener ahead of the Australian Open.

Badosa and Kontaveit both got as high as number two in the world rankings last year, but neither currently sits in the top 10, with Badosa down at number 11 and Kontaveit 17th.

Tuesday's tussle in South Australia went the way of the Spaniard, with Badosa scoring a 6-4 6-3 win against her Estonian opponent.

She had five aces and only one double fault, winning 77 per cent of points when landing a first serve in.

Another Estonian awaits her at the last-16 stage in veteran campaigner Kaia Kanepi and Badosa is happy with how she had begun the tournament.

"I think I started really good," Badosa said in an on-court interview. "I was serving very well. I was going for the first shots."

Asked about signs of improvement with her serve, Badosa said: "It depends on the day, to be honest. I worked a lot this past 10 days and was really focused on that, so I'm happy about that."

Czech Barbora Krejcikova, another player with a career-high ranking of number two, earned a second-round shot at Russian Daria Kasatkina after winning 6-2 7-6 (7-3) against last year's runner-up Alison Riske-Amritraj.

Other winners in Adelaide on Tuesday were Amanda Anisimova, Zheng Qinwen, Veronika Kudermetova, Anna Kalinskaya and Katerina Siniakova.

At the Hobart International, second seed Elise Mertens fell 6-4 6-4 to fellow Belgian Maryna Zanevska, while French third seed Alize Cornet was also knocked out, losing 6-4 6-2 to Italy's Elisabetta Cocciaretto.

Former Australian Open champion Sofia Kenin had no such trouble, seeing off China's Zhu Lin 6-2 6-2

Petra Kvitova defeated Elena Rybakina in the pick of the first-round matches at the Adelaide International 2 on Monday.

Two-time Wimbledon winner Kvitova hit 21 winners to 12 unforced errors on her way to a 6-3 7-5 win against reigning SW19 champion Rybakina in a match lasting 87 minutes.

Belinda Bencic, a defeated finalist in this tournament in 2021, also advanced with a 6-3 6-4 win against former world number one Garbine Muguruza to maintain her positive form.

Fellow seeded players Beatriz Haddad Maia and Danielle Collins beat Sorana Cirstea and Karolina Pliskova respectively to book their places in the last 16.

At the Hobart International, favourite Marie Bouzkova saw off Jacqueline Cristian 7-6 (7-2) 6-3, while Lauren Davis defeated Sloane Stephens 6-2 6-2 in an all-American clash.

Taylor Fritz claimed the deciding victory as the United States stormed into an unassailable 3-0 lead over Italy in the United Cup final.

Jessica Pegula and Frances Tiafoe paved the way for Fritz to be the hero with their victories over Martina Trevisan and Lorenzo Musetti earlier in Sunday's final in Sydney.

While Musetti retired hurt while trailing 6-2, WTA world number three Pegula dispatched Trevisan in straight sets, carrying on the form that saw her defeat Iga Swiatek in the USA's semi-final win over Poland.

And Fritz ensured that the inaugural United Cup went his nation's way with a 7-6 (7-4) 7-6 (7-6) win over Matteo Berrettini, who clawed back the first championship point but was unable to prevent his opponent taking the second.

"It's great. It’s amazing for the team to win this event. We came in with really high hopes, or at least I did, for the event," said Fritz, who is ranked ninth in the world by the ATP after winning three titles in 2022.

"I was really happy to be in that position to clinch the match."

There were jubilant scenes as the USA team rushed to celebrate with Fritz, though Tiafoe was perhaps slightly overzealous.

"Just the emotions when you win and everyone comes running at you, it’s amazing," Fritz said. "I don’t know if you saw the replay but Frances basically headbutted me!"
