Ash Barty defeated Elena Rybakina in straight sets to claim the Adelaide International title, while Simona Halep clinched silverware in Melbourne.

World number one and heavy favourite Barty prevailed 6-3 6-2 against Rybakina to claim the Adelaide title for a second time in three seasons.

The 25-year-old recovered from 40-15 down in the seventh game and went on to immediately earn the only break of the opening set.

Barty did not look back as she held throughout the second set, meaning she went 35 consecutive games without losing serve to conclude the tournament.

After securing a 14th WTA singles title in a little over an hour, Barty now turns focus to next week's Sydney Tennis Classic ahead of beginning her Australian Open campaign.

"I feel good leading up to an Australian Open like I have every year," Barty, who hit 17 winners to 13 unforced errors, said after seeing off Rybakina. 

"Each and every preparation is unique. We take it for what comes and what it is, move on, try and do the best that we can in every opportunity.

"It has absolutely no effect on the way that I prepare or the way I'm thinking leading forward just because it's a Grand Slam. It doesn't change for us."

Halep, one of Barty's likely rivals for the Australian Open crown, also made a bright start to the year by overcoming Veronika Kudermetova in the Melbourne Summer Set 1 final.

The number two seed, who is aiming to put last year's injury-ravaged and trophyless season behind her, came out on top 6-2 6-3.

She recovered from an early break down in the first set and again in the second to make it 23 career titles, and a first since the 2020 Italian Open.

It could easily have been a different story, however, as Kudermetova had three break points to move 3-0 ahead in the second set, but the Russian could not take full advantage.

Amanda Anisimova defeated Aliaksandra Sasnovich at the Melbourne Summer Set 2 final to claim the first WTA title of the season, and her second overall.

Belarusian qualifier Sasnovich hit back in style to take the second set 6-1 after losing the opener 7-5, but Anisimova recovered from a break down to edge the deciding set 6-4.

In doing so, Anisimova became the first American to win a title on Australian soil since Sofia Kenin's Australian Open triumph in 2020.

Ash Barty moved a step closer to a second Adelaide International title in three seasons as she crushed defending champion Iga Swiatek's hopes in the semi-finals.

Competing as a stepping stone towards her principal goal of challenging for the Australian Open title later in the month, home favourite Barty sped to a 6-2 6-4 win over the 2020 French Open winner.

She served fewer aces than Swiatek – five to the seven fired down by the 20-year-old Pole – but Barty's powerful forehand proved decisive as she made snappy work of ending the contest.

Barty will face Elena Rybakina in Sunday's final, after the Kazakh beat Japan's Misaki Doi 6-4 6-3. Queenslander Barty beat Dayana Yastremska in the 2020 final.

Having won the French Open and Wimbledon already in her career, Barty will be the favourite at the Australian Open, which begins on January 17 in Melbourne.

The world number one, by seeing off ninth-ranked Swiatek, boosted her win-loss record against top-10 WTA rivals to 8-1 since the beginning of last year.

Barty said, quoted on the WTA website: "It is exciting to be able to play well here in Australia. This is where I want to play my best tennis. I want to give myself an opportunity to play for titles in Australia.

"It's something really exciting to start the year off as an Aussie player in front of our home fans."

Reflecting on a positive performance, Barty, who has also reached the doubles final with Storm Sanders, said: "I felt like on Iga's service games I was able to get into most of them, which is important when you're playing someone who can dominate with that first ball and first strike.

"I felt like I was able to build pressure over time, making her play a lot of balls on her service games, not giving her too many cheapies."

Swiatek is entered into next week's Sydney Classic and learned on Saturday that she faces a testing opener there, having been drawn to face Great Britain's US Open champion Emma Raducanu in a standout first-round match.

At the Melbourne Summer Set 2 tournament, Russian third seed Daria Kasatkina suffered a shock 6-2 6-0 semi-final defeat at the hands of American world number 78 Amanda Anisimova.

Anisimova goes on to face fellow unseeded player Aliaksandra Sasnovich for the title, after the Belarusian beat American Ann Li 7-6 (7-4) 2-6 6-3.

Ash Barty set a new personal best for aces in a match as she rifled 17 past Sofia Kenin on the way through to the Adelaide International 1 semi-finals.

Reigning Wimbledon champion Barty won 31 of 32 points on first serve in a ruthless 6-3 6-4 victory over the 2020 Australian Open winner.

It sets up a tantalising last-four clash with Poland's defending champion Iga Swiatek, who is a frequent practice partner for Australian home favourite Barty.

Explaining her stunning serving performance, Barty said: "I think towards the end Sofia was kind of leaning one way or the other, and I was able to kind of get up and hit my spots."

Facing former French Open winner Swiatek will be a major early-season test for the world number one, with the Warsaw-born 20-year-old fending off former grand slam winner Victoria Azarenka 6-3 2-6 6-1 in Friday's quarter-final.

The other semi-final in Adelaide will see Misaki Doi take on Elena Rybakina after both won in three sets to get there, seeing off Kaja Juvan and Shelby Rogers respectively.

Melbourne Park is staging two tournaments this week, and there is the prospect of a starry final in Melbourne Summer Set 1, with Naomi Osaka and Simona Halep both through to the last four.

Top seed Osaka beat experienced German Andrea Petkovic 6-1 7-5, while second seed Halep had to scrap for a 6-2 5-7 6-4 win against Viktorija Golubic of Switzerland.

Osaka took inspiration from Petkovic's fight in the second set of their contest. Quoted on the tournament website, she said: "It was really cool how she didn't give up for any point, so I just felt like I should do the same thing and see what happens."

Halep said her encounter with Golubic had been "really difficult", adding: "I didn't really trust that I can win this match, but I fought to the end, and I'm very proud of this."

Saturday's semi-finals of Melbourne Summer Set 2 will seed Daria Kasatkina take on Amanda Anisimova, while Ann Li plays Aliaksandra Sasnovich.

Ash Barty produced an impressive comeback to defeat Coco Gauff in her first singles match since the US Open.

World number one Barty moved into the quarter-finals of the Adelaide International with a battling 4-6 7-5 6-1 triumph.

The home hope, who is favourite to win the Australian Open when it starts later this month, was a set and a break down against the American wonderkid before ultimately progressing in two hours and 12 minutes.

Exhausted after a six-month road trip that included Wimbledon glory last year, Barty took a break from the WTA Tour after her third-round exit at Flushing Meadows on September 5.

Her return came in a marquee matchup at the WTA 500 event which did not disappoint, as Barty battled to win 11 of the last 13 games and prevail.

The victor stemmed the early errors she was making on the forehand side, with Gauff paying the price for only converting three of her 15 break-point opportunities. 

It was only the second meeting between Barty and Gauff, with the Australian having to retire with an arm injury while leading their first encounter in Rome last year.

"I felt like I played a pretty good quality match considering it was my first match in a few months," said Barty.

"In the first set I was able to create opportunities but just was a little bit slack on the execution, rusty in the sense of stringing quality points together.

"Midway through the second set I was able to find my rhythm a little bit better on serve and just continued to be aggressive on my forehand. I just found execution a little bit more.

"Coco played great and forced me to hit a lot of balls. I felt I got better and better as the match went on. It was nice to get some court time."

An intriguing last-eight tie lies in wait for Barty. She will either play former Australian Open champion Sofia Kenin or compatriot Ajla Tomljanovic.

And there was more good news for Barty as two of her main rivals for glory were eliminated.

Second seed Aryna Sabalenka was surprisingly beaten as Kaja Juvan, the world number 100, prevailed 7-6 (8-6) 6-1.

Maria Sakkari, the third seed, also crashed out, beaten in three sets by Shelby Rogers, the player who knocked Barty out of the US Open the last time the Australian was on court.

There are two other tournaments taking place this week, both at WTA 250 level.

At Melbourne Summer Set 1, second seed Simona Halep joined Naomi Osaka in round two with a routine 6-4 6-2 win over Destanee Aiava.

The field is not as strong at Melbourne Summer Set 2, where the highest seed remaining, Daria Kasatkina, progressed after opponent Anna Kalinskaya, having already lost the first set, withdrew through injury.

World number one Ash Barty will start her 2022 season at the Adelaide International along with eight of the other current 10 top players in the world.

Barty has held top spot in the women's rankings since September 2019 and collected five titles – including Wimbledon – in the 2021 season but missed the French Open with a hip injury.

She also opted to not play in the season-ending WTA Finals in Mexico due to coronavirus-enforced quarantine concerns that could disrupt her preparation for the following campaign.

The Women's Tennis Association (WTA) confirmed on Friday that Barty would begin her 2022 season in Adelaide on January 2, along with defending champion Iga Swiatek, WTA Finals victor Garbine Muguruza and Roland Garros winner Barbora Krejcikova, as the world's elite players prepare for the Australian Open.

The entry list for the WTA 500 tournaments also includes Tokyo Olympics gold medallist Barbara Bencic, who finished runner-up to Swiatek in 2021, former world number one Karolina Pliskova and US Open runner-up Leylah Fernandez.

The field boasts 12 major trophies between them, but three grand slam winners will kick-start their seasons in Melbourne the day after.

Naomi Osaka, who is aiming to defend her title at the Australian Open, gets her preparations underway in the Melbourne Summer Set.

Two-time major winner Simona Halep and reigning US Open champion Emma Raducanu will play in the Melbourne Summer Set.

The trio are among 20 of the top 50 ranked players in the world for the two WTA 250 tournaments starting on January 3, with the entry list split between the competitions the week before matches start.

Raducanu will feature in just her eighth Tour-level event, and her fourth tournament since winning her first major, while Osaka will be appearing for the first time since an early defeat in the third round of the US Open to Fernandez.

Novak Djokovic has been included in the official entry list for the 2022 Australian Open, with Tennis Australia adamant that no loopholes are being explored.

The world number one, who has won nine of his 20 grand slam titles in Melbourne, has not yet disclosed his COVID-19 vaccination status, meaning there is doubt over whether he will be able to participate.

Every person competing or attending the grand slam next month will need to have been fully vaccinated against coronavirus.

However, despite the uncertainty, the 34-year-old was named in the official list of players for the tournament draw.

Djokovic had already been named in Serbia's team for the ATP Cup, which is to be held in Sydney, leading to speculation that he could enter Australia by travelling directly to New South Wales, which has different COVID-19 restrictions to the state of Victoria, and may then seek a medical exemption to get around the rules applying to unvaccinated travellers.

James Merlino, Victoria's deputy premier, responded to these reports, which also suggested Djokovic had the backing of Tennis Australia.

"My view on this is really clear and really simple," Merlino said on Wednesday. "Everyone's looking forward to the Australian Open and everyone who will attend – spectators, players, officials, staff – everyone is expected to be fully vaccinated.

"They're the rules. Medical exemptions are just that – it's not a loophole for privileged tennis players. It is a medical exemption in exceptional circumstances if you have an acute medical condition."

Tennis Australia responded to Merlino's comments with a statement of their own.

"Any suggestion that Tennis Australia is seeking 'loopholes' within this process is simply untrue. Adjudicating on medical exemptions is the domain of independent medical experts. We are not in a position to influence this process and nor would we," the statement read.

"Any application for a medical exemption must follow strict government guidelines based on ATAGI (Australian Technical Advisory Group on Immunisation) clinical advice. This is the same process that applies to any person wanting to enter Australia."

While Djokovic's participation is unclear, Serena Williams is a big-name absentee. The 40-year-old, who is one shy of matching Margaret Court's record tally of 23 grand slams, had been expected to play in Melbourne.

Roger Federer had already confirmed his absence, but Rafael Nadal is set to compete for the first time since August.

World number two and US Open champion Daniil Medvedev takes his place in the draw, as does 2020 Australian Open finalist Dominic Thiem.

Australian world number one Ash Barty headlines the women's field, with Naomi Osaka, US Open winner Emma Raducanu and WTA Finals champion Garbine Muguruza also in the draw.

Bianca Andreescu, the 2019 US Open champion, has decided to skip the event to focus on her mental wellbeing.

Ash Barty has won the WTA's Player of the Year award for a second time, while Emma Raducanu's sensational 2021 season was capped with the Newcomer of the Year prize on Tuesday.

Barty collected the tour's top individual year-end award in 2019, having won the French Open and finished that season as the world number one.

And after Sofia Kenin succeeded her in 2020, Barty is back on top this year.

This was the third straight season the Australian superstar claimed the year-end number one ranking, and it saw her land a second major title at Wimbledon. Barty's five WTA titles in 2021 were unsurpassed.

But she has had to share the limelight in recent months with Raducanu, and that was the case again as the 19-year-old Briton was unsurprisingly hailed as the tour's star newcomer.

Raducanu became the first qualifier to win a grand slam when she swept to glory at the US Open, having also impressed in a run to the last 16 at Wimbledon.

The teenager, who has risen from 343rd to 19th in the rankings in the past year, won 10 straight matches without dropping a set from the first qualifying round to the final at Flushing Meadows.

Elsewhere, Roland Garros champion Barbora Krejcikova collected a pair of awards, scooping Most Improved Player and, alongside Olympic, WTA Finals and French Open-winning partner Katerina Siniakova, the Doubles Team of the Year.

Carla Suarez Navarro, who retired in 2020 and was then diagnosed with Hodgkin's Lymphoma, returned to the tour cancer free in 2021 for a farewell season and carried off the Comeback Player of the Year award.

Ash Barty has announced her engagement to Liverpool fan and golfer Garry Kissick, capping a memorable year in style.

Barty added another sparkler to her collection when she revealed an engagement ring on Tuesday, having already landed the glistening Wimbledon trophy and an Olympic medal in the 2021 season.

She posted a picture of herself and Kissick on Instagram, showing off her ring and captioning the shot "Future Husband".

Kissick is a trainee professional at Brookwater Golf Club, a venue close to Brisbane, and is often seen in a Liverpool Football Club shirt, as was the case with the engagement picture.

He and Barty have visited Liverpool's home ground of Anfield together.

Speaking about having the likes of Kissick and coach Craig Tyzzer with her on the road, Barty said during her run to the Wimbledon title in July: "It's nice to be able to share some of these awesome moments with those that put so much time and energy into my career and allow me, encourage me, help me kind of work and figure out a plan and a way that they try and achieve our dreams. I think being able to share that with them is really special."

Barty won a bronze in mixed doubles at Tokyo 2020 alongside long-time friend John Peers, describing that achievement as "a dream come true".

She also won the Yarra Valley Classic, the Stuttgart Open, and WTA 1000 titles at Miami and Cincinnati before calling time on her season after a third-round exit from the US Open, where she lost to Shelby Rogers.

Barty finished the season as world number one for a third successive year, despite her recent inactivity.

She said a major triumph in her homeland was a priority for 2022, saying: "My focus is now on the Australian summer and doing everything I can to win the Australian Open. I can't wait to play at home again."

World number one Ash Barty will skip the WTA Finals to focus on her preparations for the Australian Open and the 2022 season.

Barty won five titles in 2021, including a victory at Wimbledon that marked the second grand slam title of her career.

She reached the semi-finals of her home major in 2019 and her determination to go one better in 2022 has led Barty to call an early end to her 2021 campaign.

"I wanted to let everyone know that I won't be competing in any further tournaments in 2021, including the WTA Finals in Mexico," said Barty.

"It was a difficult decision but I need to prioritise my body and my recovery from our 2021 season and focus on having the strongest preseason for the Australian summer.

"With the ongoing challenges of travelling back to Queensland and quarantine requirements, I am not willing to compromise my preparation for January.

"I wish the WTA team and the players all the best for a successful WTA Finals and rest of the year.

"My focus is now on the Australian summer and doing everything I can to win the Australian Open.

"I can't wait to play at home again."

Wimbledon champion and world number one Ash Barty has withdrawn from this month's Indian Wells Open. 

The Australian has not played since her surprise third-round defeat to Shelby Rogers at the US Open last month. 

Barty follows four-time grand slam champion Naomi Osaka in pulling out of the California event, the final WTA 1000 tournament of the year. 

The 25-year-old had indicated after her defeat at Flushing Meadows that she planned to play at Indian Wells. 

Defending champion Bianca Andreescu heads a strong field, with world number two Aryna Sabalenka, Wimbledon finalist Karolina Pliskova, French Open champion Barbora Krejcikova, Olympic bronze medalist Elina Svitolina and last year's Australian Open champion Sofia Kenin all taking part. 

Three other previous winners – Simona Halep, Elena Vesnina and Victoria Azarenka – will also be present, along with teenager Leylah Fernandez, who reached the US Open final. 

Emma Raducanu came within one point of a sensational double bagel against Sara Sorribes Tormo and could face Ash Barty next at the US Open.

The 18-year-old Briton came through qualifying to make her Flushing Meadows bow this week.

And now Raducanu is remarkably into week two without dropping a set.

She saved her best performance yet for round three, winning 6-0 6-1 after passing up a match point on Sorribes Tormo's serve that would have sealed a flawless result.

Her place in the fourth round was a fine consolation for Raducanu, who reached the same stage at Wimbledon in July, then appearing in a grand slam main draw for the first time.

A match against Ajla Tomljanovic proved a step too far at the All England Club, but Raducanu may now get an opportunity to advance against another Australian.

If Barty beats Shelby Rogers later on Saturday, the world number one will face Raducanu next week – presumably far away from the Court 17 the teenager was consigned to on this occasion.

Given Sorribes Tormo beat Barty in straight sets in the first round of this year's Olympic Games, Raducanu should have nothing to fear.

"It's been two weeks in New York now," she told Prime Video. "And into the third week – I never thought I'd be here, but I'm just so, so excited."

Raducanu said of her latest triumph: "I was playing very well. I know Sara is an extremely tough opponent – she doesn't make a mistake, so you have to be on your game every single point.

"I had to work so hard, and there were some really, really long deuce games that could have gone either way, so I'm just really happy that I managed to maintain and stay on it and win in the end."

It was a far more comprehensive success than Raducanu was willing to admit, though, with the world number 150 having 11 break point opportunities to her opponent's zero.

Raducanu's blistering forehand averaged 92 miles per hour on serve, while she played 23 winners.

"Honestly, for this one, the plan was I had to hit through her, I had to hit the corners," she added. "If you trade against her, you're probably going to come out second best.

"I just took the game to her and hit more winners than errors today."

World number one Ash Barty said her serving struggles are "not a concern" after advancing to the US Open third round.

Barty continued her quest for a third grand slam title and first US Open crown with a 6-1 7-5 win over teenage prodigy Clara Tauson on Thursday.

Reigning Wimbledon champion Barty hit 33 winners and fired down 11 aces to see off the 18-year-old on Arthur Ashe Stadium in New York.

Barty, though, had to stave off a late challenge just like the top seed did against Vera Zvonareva in the opening round.

After she faltered to serve out the match at 5-4 in the second set of her victory over Tauson, Barty said: "It's happened a few times, but I have won 40-odd matches [this year] and it hasn’t happened a lot.

"It's just a few of those games I haven't been able to get up and hit my spots on first serves.

"When you give good players looks at second serves, you're going to get hurt. It's simple as that. It’s not a concern."

Barty leads the WTA Tour this season for titles won (five), match victories (42), finals reached (six), aces (319) and top-10 wins (seven).

"There's room for improvement, without a doubt, but there's room for improvement every single day," said Barty, who has never reached the quarter-finals at Flushing Meadows.

"Credit to her, she was a little bit more aggressive in that second set. I got a little bit passive and just let my energy drop and allowed her back in.

"We'll go back and have a chat about the matches and, once we get back on the practice court, try and fix a few things up, trust myself and trying to continue to play how I want to play."

Next up for Australian star Barty is either 2020 US Open quarter-finalist Shelby Rogers or Sorana Cirstea.

World number one Ash Barty was relieved but happy with her response after surviving a first-round scare against Vera Zvonareva at the US Open.

Barty – the top seed back at Flushing Meadows after skipping the 2020 event due to the coronavirus pandemic – booked her spot in the second round with a 6-1 7-6 (9-7) victory but the Wimbledon champion endured a challenging opener in New York on Tuesday.

Despite firing down 11 aces to improve her WTA Tour-leading tally to 300 in 2021, and hitting 31 winners, veteran Zvonareva was a tricky first-up opponent for Australian star Barty.

A US Open and Wimbledon runner-up in 2010, Zvonareva made life difficult for Barty in the second set, earning a chance to force a decider but the 36-year-old was unable to capitalise at 7-6 in the tie-break.

Afterwards, Barty – who ranks first this season for titles (five), match victories (41), finals reached (six) and top-10 victories (seven) – told reporters: "Obviously a tough one against Vera straight up.

"She's an experienced campaigner. She knows how to get herself into matches. I think all in all, adapting to conditions was a little bit slower than I probably would have liked [but] we're through. We have another chance to improve on that in the next round.

"I think when my back was against the wall late in that buster, I came up with some really good stuff. That's all we can ask is when your back is against the wall, you trust yourself, you go out there and pick your spots and hit them."

Two-time grand slam champion Barty – fresh off winning in Cincinnati as Clara Tauson awaits in round two – added: "It obviously got really tense in that second set - tight - and in the bigger moments I was able to be aggressive and trust myself and that was a massive thing today.

"There were a couple of games where I had lapses in concentration but I was able to come through in straight sets and now we go back to the drawing board, work on a few things and we'll be as happy as Larry.

"I'm certainly happy to be through and playing again here in New York."

Novak Djokovic is a strong favourite to become only the third man to complete a calendar Grand Slam and make history at the US Open.

Djokovic has won all three majors this year and can complete a 2021 clean sweep at Flushing Meadows.

The irrepressible world number one would also go beyond Roger Federer and Rafael Nadal – both absent due to injury – with 21 grand slam singles titles if he triumphs in New York.

There will be no elusive record-equalling 24th major singles crown for Serena Williams, who has not recovered from the hamstring injury she suffered at Wimbledon.

With Ash Barty and Naomi Osaka the leading contenders to take the women's singles title, Stats Perform use Opta data to preview the final grand slam of the year.

WHAT A DIFFERENCE A YEAR MAKES FOR DOMINANT DJOKOVIC

Djokovic was thrown out of the US Open last year after accidentally hitting a line judge in the throat with a tennis ball.

The 34-year-old arrived in New York in far better spirits than when he left last September, having taken on all comers this year.

Djokovic missed out on a Golden Slam when he failed to win Olympic gold in Tokyo, but he could join Don Budge (1938) and Rod Laver (1962 and 1969) as the only men to win all four majors in the same year.

Maureen Connolly (1953), Margaret Court (970) and Steffi Graf (1988) are the only women to achieve the incredible feat.

BARTY TO GO BACK-TO-BACK?

Barty became the first Australian woman to win a Wimbledon singles title for 41 years in July.

Not since Williams in 2012 has a player claimed back-to-back women's singles major crowns in the same year, but Barty could take some stopping.

She could become the ninth woman in the Open Era to win Wimbledon and the US Open in the same season. 

Margaret Court, Billie Jean King, Chris Evert, Martina Navratilova, Steffi Graf, Martina Hingis, Venus Williams and Serena Williams can boast that achievement.

OSAKA BACK TO DEFEND TITLE

Japanese sensation Osaka won her third grand slam title at Flushing Meadows last September and went on to add a fourth at the Australian Open this year.

Osaka returns to grand slam action for the first time since withdrawing from the French Open, citing struggles with her mental health.

The world number three could be the first woman to win consecutive titles at Flushing Meadows since Serena Williams claimed three in a row from 2012 to 2014.

Osaka is the only woman to win at least one major title over the past four seasons, winning the Australian Open in 2019 and 2021, as well as the US Open in 2018 and last year.

ZVEREV BIDS TO BANISH PAINFUL MEMORIES

Alexander Zverev was beaten by Dominic Thiem in his maiden grand slam final in New York last year after the German had been two sets up.

He will not have to face Thiem this time around as the defending champion is sidelined due to injury.

Zverev was the only player to serve 100 or more aces during the tournament last year, firing down 131 but also racking up more double faults (64) than anyone else.

The world number four won his fourth title of the year in Cincinnati last week but Djokovic is undoubtedly the man to beat at Flushing Meadows.

Stefanos Tsitsipas faces Andy Murray and Ash Barty will take on 2010 finalist Vera Zvonareva in the first round of the US Open.

French Open runner-up Tsitsipas and 2012 champion Murray is one of the standout matches in the opening round at Flushing Meadows.

Top seed Novak Djokovic will start his quest for a calendar Grand Slam against a qualifier in New York and could face a repeat of the Wimbledon final versus Matteo Berrettini in the last eight.

World number one Djokovic, a strong favourite for a record 21st major title with Rafael Nadal and Roger Federer absent due to injury, could do battle with Alexander Zverev at the semi-final stage.

Daniil Medvedev, the second seed, is in the bottom half with Tsitsipas, who he could come up against in the semi-final. Medvedev's first test will come against Frenchman Richard Gasquet.

Barty could come up against Iga Swiatek in the last eight and Karolina Pliskova if she makes it through to the semi-finals.

Simona Halep's encounter with Camila Giorgi is a mouthwatering first-round match, while defending champion Naomi Osaka returns to grand slam action against former US Open junior champion Marie Bouzkova.

Angelique Kerber could be a tough fourth round opponent for Osaka. Close friends Madison Keys and Sloane Stephens meet in another eye-catching first-round match.

There will be no Serena or Venus Williams at the final major of the year due to injuries.
