Coco Gauff is excited about the prospect of players from the United States winning both singles titles at the same grand slam again following a bright start to the Australian Open for the men.

The last American to win the men's singles crown at any grand slam was Andy Roddick at the 2003 US Open.

The USA is still way out in front for all-time grand slam men's singles titles with 147, though 19 years and counting is comfortably their worst barren spell during the Open Era.

This comes after 2003 was the 15th year in a row that the USA had at least one champion in the men's majors, with the likes of Pete Sampras and Andre Agassi both prolific winners.

Of course, the drought did not extend to the women, with Serena Williams, Venus Williams, Sloane Stephens and Sofia Kenin all winning at least once since Roddick's success at Flushing Meadows.

But with eight of the last 32 in the men's draw representing the USA, there is a renewed sense of optimism – and that is even accounting for their highest seed, number eight Taylor Fritz, falling in the second round.

Gauff – who beat compatriot Bernarda Pera on Friday – is the USA's next great female hope, and she is looking forward to the day Americans claim a men's and women's double at the same slam.

Asked if there was a refreshing sense of excitement around the men, Gauff said: "Yeah, definitely. I definitely think on the men's side they're thriving.

"It's like eight people in the round of 32 I saw. I think it's incredible. It's just people that you've been rooting for for a long time, and some new faces, too, that people probably haven't been rooting for a long time but fell in love with.

"I'm just excited. On the women's side, we're always like, 'the guys need to catch up, you guys need to put in your work'. I think they're here. I'm hoping that eventually, hopefully soon, we'll have our slam champion on the men's side.

"That would be pretty cool if an American woman and guy could win the same slam. I don't know when the last time that's happened or if it's ever happened. I'll be pretty excited."

Coincidentally, it last happened at Melbourne Park. In 2003, Andre Agassi and Serena Williams were victorious at the Australian Open.

Gauff is not getting carried away, but her perception is there is genuine belief among the men now, which is being fed by unity.

"I definitely think the guys are feeling it," she said. "You can see it. I think it really comes from, not the women, but the same dynamic, where everybody is doing well, so it makes you want to do well.

"We're all not competing with each other but pushing each other. I think that's what the men are having.

"They're competing against each other but also pushing each other to be better. I'm pretty sure all the American guys get along, at least that's what I think."

There were setbacks to American men's title hopes on Friday as Frances Tiafoe and Mackenzie McDonald both lost at the last-32 stage, but there was a hugely notable win too, with Sebastian Korda beating seventh seed, two-time Australian Open runner-up and former US Open champion Daniil Medvedev in straight sets.

Venus Williams has withdrawn from the Australian Open due to injury and Iga Swiatek's participation could be in doubt.

The American was given a wildcard for the first grand slam of the year, but suffered an injury setback at the ASB Classic this week.

Williams was beaten by Zhu Lin of China in the second round of the tournament in Auckland on Thursday and it was revealed on Saturday she will not play at Melbourne Park.

The 42-year-old, who has shown incredible longevity in her illustrious career, is a seven-time grand slams singles champion and winner of 14 major doubles titles.

Williams won four of her grand slam doubles crowns at the Australian Open and lost her two singles finals in 2003 and 2017.

Australian Kim Birrell has been awarded Williams' wildcard place nine days before the tournament gets under way.

Meanwhile, world number one Swiatek has withdrawn from the Adelaide International 2 next week due to a shoulder injury.

Swiatek was in tears after she was beaten by Jessica Pegula while representing Poland against the United States in the United Cup on Friday.

Linda Noskova produced the biggest win of her career as she defeated Daria Kasatkina 6-3 6-7 (2-7) 6-3 at the Adelaide International on Monday.

The 18-year-old Czech was impressive against the third seed as she recorded her first win against anyone in the top 30 of the world rankings.

Fourth seed Veronika Kudermetova eased past Amanda Anisimova in just an hour and 15 minutes, winning 6-3 6-0, while Liudmila Samsonova will face second seed Aryna Sabalenka in the next round after coming from a set down to beat Zhang Shuai 5-7 6-3 6-0.

Irina-Camelia Begu and Elena Rybakina also both came from behind to secure wins, with the latter beating fifth seed Danielle Collins to set up a last-16 clash against Ukrainian Marta Kostyuk, who beat Jaimee Fourlis 6-1 3-6 6-4.

At the ASB Classic in Auckland, 42-year-old Venus Williams comfortably overcame her 21-year-old opponent Katie Volynets 7-6 (7-4) 6-2, and will play China's Zhu Lin next after she eliminated sixth seed Madison Brengle 4-6 7-6 (8-6) 6-4.

Third seed Leylah Fernandez beat Brenda Fruhvirtova 6-1 6-1 to set up a last-16 tie with Julia Grabher after she defeated Tereza Martincova in three sets.

Eighth seed Rebecca Marino is through after beating Dalma Galfi in straight sets and will now face Ysaline Bonaventure, who eventually put away Caty McNally 5-7 6-4 6-4.

Viktoria Kuzmova led fourth seed Bernarda Pera 5-4 in the opening set when rain stopped play for the day.

Tennis icon Venus Williams will compete in her 22nd Australian Open in January after it was announced on Sunday she had been awarded a wildcard entry.

Williams, 42, is a seven-time grand slam singles champion, but she only played four competitive matches in 2022, losing all four.

A five-time Wimbledon winner with two US Open titles on the singles side, Williams is also one of the sport's most decorated doubles players, collecting another 14 grand slam doubles titles, including four in Australia.

She won the Australian Open doubles in 2001, 2003, 2009 and 2010, while making the singles final in both 2003 and 2017.

In the press release announcing her wildcard, Williams confirmed her plans to compete once again in Melbourne.

"I am very excited to be returning to Melbourne to compete at the Australian Open in January," she said.

"I've been competing in the country for over 20 years now and the Australian community has always supported me wholeheartedly.

"It will be an honour to play for the fans again and I'm looking forward to making more memories at the tournament this year."

It remains to be seen if she will be joined by her sister, Serena, who is a seven-time singles champion at the event and Venus' partner for her four doubles successes.

After her exit from the US Open, Serena heavily implied she was weighing up another go down under, saying "I always did love Australia".

Coco Gauff believes her and fellow teen Robin Montgomery are products of Venus and Serena Williams' legacy as the Roland Garros runner-up looks to inspire the next generation of African-American talent.

The two 18-year-old Americans collided in the opening round of the San Diego Open, with Gauff prevailing 6-3 6-3 in what was her first match since defeat by Caroline Garcia in the US Open quarter-finals last month.

This season's Roland Garros finalist is widely believed to be the next dominant player from her nation following the retirement of Serena Williams at Flushing Meadows.

Along with sister Venus, the Williams sisters won a combined 30 major singles titles during their highly decorated careers, as well as 14 grand slam triumphs in women's doubles, in which they are also the only pair to win a career golden slam.

And Gauff hopes she can follow the sisters' well-trodden footsteps, while also going on to serve as an inspiration herself.

"It definitely affects the future a lot," she said during her post-match interview. "If Serena and Venus saw this today; two 18-year-olds - both African-American - playing on the WTA 500 level - I think they would be proud.

"I think both of us are products of their legacy. I'm grateful that I had those examples to follow after, and I hope I can be an example myself."

On the match, she said: "It was the first time playing someone younger than me in probably at least seven years. It was definitely a different feeling for me.

"I know Robin very well, we went on a couple of USTA trips back when we were about eight-years-old. She played really well, I expected a good level from her. I was pretty impressed with how well she was striking the ball; it was difficult for me."

Serena and Venus Williams saw hopes of one last US Open glory run together scuppered by a Czech pair who apologised for knocking out the American superstars.

The Williams sisters lost 7-6 (7-5) 6-4 against Lucie Hradecka and Linda Noskova on Arthur Ashe Stadium, with the doubles match given top billing in the New York night session.

Such scheduling had previously been unheard of, but such is the attention being foisted on the sisters that first-round doubles encounter was the match everyone wanted to see, knowing it could well be the last time the siblings play as a team.

Serena has indicated, albeit couched in somewhat vague terms, that this US Open will be her farewell to tennis. Venus, now 42, may follow suit and also retire from the sport.

While 40-year-old Serena remains in the singles, having beaten world number two Anett Kontaveit in round two to set up a Friday night clash with Ajla Tomljanovic, the dream of one more Flushing Meadows doubles title is over.

It was Czech-out time for the duo who have won 14 grand slam doubles titles together, and Hradecka said sorry to the partisan crowd for spoiling the party.

"I'm still in shock that we won, because we were playing for the first time with each other and I think we did a very good job," Hradecka said.

"I'm so sorry for you that we beat them, but we are so happy that we did it."

Hradecka had been planning on playing with Indian Sania Mirza, but an injury for Mirza put paid to that idea, meaning a new partner was required.

Noskova, 17, answered the 37-year-old Hradecka's call, and enjoyed a night to remember.

"Playing against the Williams sisters is a special moment for everybody, anytime," Noskova said.

"I was really lucky I could play with my doubles partner and we could win and pull out a good fight."

It was the Williams' first doubles match at a grand slam since the 2018 French Open, and their first at the US Open since 2014, and although it was a tight contest the younger pair just had the edge.

Neither sister gave an on-court interview or a press conference after the match, with all eyes now turning towards Serena's singles campaign, and the possibility of that extending deep into the second week.

Serena Williams and sister Venus were unable to advance past the first round of the doubles at the US Open, going down 7-6 (7-5) 6-4 against Czech duo Lucie Hradecka and Linda Noskova on Thursday.

It was the Williams' first doubles match at a grand slam since the 2018 French Open, and their first at the US Open since 2014, less than 24 hours after Serena's stunning upset of world number two Anett Kontaveit.

Leading 5-4 in the first set, the sisters had two opportunities to break and secure the first set, but ultimately let them slip, before going down in a competitive tiebreaker.

They were far from outclassed, winning 48 per cent (49-of-102) of the points in the opening set, and 45 per cent (33-of-74) in the second.

After going down 3-0 in the second frame, instead of rolling over, the Williams sisters fought back, pulling it back to 4-4, but that would be their last stand before dropping the next two games and the match.

There was no on-court interview for the Americans, although 17-year-old Noskova called it "a special moment" and said "I was really lucky" for the opportunity to play against her heroes.

Serena will continue her singles campaign in the third round on Saturday night against unseeded Australian Ajla Tomljanovic.

Venus Williams says she is "focused" on her US Open women's doubles pairing with sister Serena following her first round exit to Alison Van Uytvanck on Tuesday, adding that she couldn't turn down "the boss" one more time.

The seven-time grand slam singles champion saw her solo stint at Flushing Meadows come to an early end following a 6-1 7-6 (7-5) straight sets loss to the Belgian at Arthur Ashe Stadium.

Following younger sister Serena's announcement earlier this year that she intended to step back from top-level tennis following the conclusion of the final tennis major of the year, many had wondered if Venus would follow suit.

But speaking after her defeat, Williams eschewed questions on her future, simply stating: "Right now, I'm just focused on the doubles."

The return of the Williams sister pairing – the only duo to have won the Career Golden Slam in women's doubles – has added a further degree of excitement to Serena's farewell tour.

When asked how their on-court reunion came about, Venus stated it was her sibling who got the ball rolling, adding: "It was Serena's idea.

"She's the boss, so I do whatever she tells me to do! I don't think we have played since 2016, but I might be getting that wrong. We have had some great wins. It would be nice to add some more."

Former world number one Williams made her 91st grand slam main draw singles appearance with her match against Van Uytvanck, a record for both the men's and women's game.

It is a testament to her longevity that 58 players in the main draw had not been born when she made her grand slam debut at the 1996 French Open – including this year's Wimbledon champion Elena Rybakina, who also suffered a first round loss to the unseeded Clara Burel.

Serena Williams will go out with "full force" when she begins her final US Open campaign before retiring, according to Chris Evert.

Williams will have one last chance to match Margaret Court's all-time record of 24 grand slam singles titles at Flushing Meadows, as well as an opportunity to wave goodbye to her adoring fans on home soil.

While a challenge for the trophy looks highly improbable for Williams this time around, fellow six-time US Open winner Evert suspects the 40-year-old will take some shifting from the draw.

According to Evert, "the edge is off" when it comes to Williams and her remaining tennis goals, meaning she has reconciled herself to the likelihood of finishing her career with 23 singles majors.

Williams has revealed family matters and business interests were key to her decision to "evolve away" from the sport, and with her on-court returns diminishing, now seems the time to head in that direction.

Yet Evert can see Williams, who faces Danka Kovinic in round one in New York, giving a good account of herself during her US Open swansong.

"Serena isn't coming out to play her last match; she's coming out with full force," Evert said on ESPN. 

"The way she's been practising this week, she's here to compete, she's here to win, and I don't even think she's thinking about retirement at this stage."

Williams holds a 106-14 win-loss record in singles at the US Open. Her match wins tally at Flushing Meadows is the highest by any woman at the competition in the Open Era, and only Martina Navratilova has more at a single slam, achieving an astonishing 120 victories at Wimbledon.

Williams and Evert lead the way in women's US Open titles in the professional era (since 1968), and regardless of final grand slam tallies, there will always be debate over who ranks as the greatest player of all time.

Williams certainly has a strong case, yet Navratilova (1,442), Evert (1,309) and Steffi Graf (900) all won more WTA-level matches than Williams (856), who often played a limited schedule.

Court has the most grand slam titles on the women's all-time list, with a remarkable haul of 64 when women's doubles and mixed doubles are included. Navratilova is next with 59, before Williams and Billie Jean King sit joint third with 39 majors apiece.

Scheduling self-preservation has allowed Williams to play on for so long, and John McEnroe has raised the question of what might happen if his fellow American surprises herself by clinching a seventh Flushing Meadows triumph. 

"If she did happen to win this, don't you think it'd be tempting to go and break the record?" McEnroe asked.

Four-time US Open singles champion McEnroe added: "I think she's accepting, as much as Serena Williams can, that she's not going to win this.

"Maybe deep down she's found some sort of belief that maybe somehow, if she gets the right set of situations going, she can make a real run."

More realistic, in McEnroe's mind, is the prospect of Williams and sister Venus having a deep run in the doubles after they were handed a wildcard.

As a partnership, the siblings have won 14 grand slam doubles titles, never losing in a final at the majors.

"The two of them in doubles, where they're covering half the court and they're still able to do their thing, that would be a hell of a way to go out," McEnroe said.

Serena and Venus Williams have accepted a wildcard entry to play the women's doubles at the US Open.

The two-time doubles winners at Flushing Meadows are likely to appear at the tournament for the final time in 2022, with Serena having already announced her intentions to soon retire from tennis.

Both sisters have entered the singles draw, with Serena facing Danka Kovinic in round one while Venus begins her campaign against Alison van Uytvanck.

The pair have not played a major doubles event together since the 2018 French Open, suffering defeat in the third round, and were last paired in New York in 2014, when they reached the quarter-finals.

However, the duo boast 14 major doubles titles and three Olympic gold medals together and are to be reunited again after the US Open announced the 14 wildcard pairs for the doubles events on Saturday.

Serena's involvement at the US Open begins on Monday, with Venus following on Tuesday, before the first round of the women's doubles is scheduled for Wednesday and Thursday.

Serena Williams highlighted the first day of the Canadian Open, defeating Nuria Parrizas-Diaz 6-3 6-4 for her first win since the 2021 French Open.

In doing so, Williams became the fourth player since 2000 to win a WTA-level main draw match after turning 40, joining sister Venus Williams, as well as Kimiko Date Krumm and Martina Navratilova.

She also claimed the all-time record for wins at the Canadian Open, with 35, now one more than Chris Evert.

"I guess there’s just a light at the end of the tunnel," Williams said after the match. "I don’t know, I’m getting closer to the light. Lately that's been it for me. I can’t wait to get to that light."

She added: "I love playing though, so it’s like amazing. But I can’t do this forever. Sometimes you just want to try your best to enjoy the moments and do the best that you can."

Williams' older sister Venus, 42, was beaten on Monday by Swiss Jil Teichmann 6-2 6-3 with the match finshing after midnight following a delayed start due to rain.

One of the three seeded players in action on Monday, 15th seed Simona Halep had no issues cruising through the challenge of Donna Vekic 6-0 6-2.

It was similarly smooth sailing for 14th seed Karolina Pliskova in her all-Czech showdown against Barbora Krejcikova, winning 6-3 6-4, while Latvian 16th seed Jelena Ostapenko handled the challenge of Ukraine's Anhelina Kalinina 6-4 6-2.

Kazakhstan's Elena Rybakina defeated in-form qualifier Marie Bouzkova 7-5 6-7 (3-7) 6-1, likely earning a shot at Coco Gauff if the American wins as a heavy favourite tomorrow, while Brazil's Beatriz Haddad Maia beat Italy's Martina Trevisan 6-2 2-6 6-2 in a meeting of two top-30 players.

In a pair of all-American battles, Sloane Stephens edged Sofia Kenin 6-2 7-6 (7-5) 7-5, and world number 187 Asia Muhammad upset world number 25 Madison Keys in straight sets 7-6 (7-5) 6-4.

Alize Cornet defeated her French compatriot Caroline Garcia 3-6 6-3 6-3, and Canada's Katherine Sebov was unable to get the job done in front of her home fans, going down 6-3 2-6 5-7 to Yulia Putintseva.

In better news for the Canadians, Leylah Fernandez won 6-4 6-7 (2-7) 6-3 over Storm Sanders, while veteran two-time Wimbledon winner Petra Kvitova was beaten by Alison Riske 6-2 4-6 6-3.

Elena Rybakina has been bundled out of the first round of the Silicon Valley Classic by Daria Kasatkina in her first game since her Wimbledon triumph last month.

Rybakina won the first set comfortably before the Russian hit back for a remarkable turnaround win, 1-6 6-2 6-0 in one hour and 40 minutes.

Seventh seed Kasatkina was the runner-up at last year's Silicon Valley Classic and found her groove to break her Rybakina six times in the second and third sets.

Rybakina sent down three of her four aces for the match in the first set, but Kasatkina adjusted to her serve and won 52.1 per cent return points for the match.

Eighth seed Karolina Pliskova fought back from a slow start to get past Katie Boulter 1-6 7-6 (7-5) 6-3, despite 16 double faults.

American Amanda Anisimova overcame compatriot Ashlyn Krueger 6-2 7-6 (7-5). US pair Madison Keys and Taylor Townsend were also winners.

Third seed Simona Halep and top seed Jessica Pegula were both among the winners in the first round at the Citi Open in Washington DC.

Two-time major winner Halep cruised past Spanish qualifier Cristina Bucsa 6-3 7-5 in one hour and 20 minutes.

Halep, playing her first match since her Wimbledon semi-final loss to Rybakina, fired 19 winners but also 33 unforced errors.

Defending champion Pegula made light work of countrywoman Hailey Baptiste 6-2 6-2 in 73 minutes.

Pegula will face unseeded Australian Daria Saville, who won in three sets over Mirjam Bjorklund, while sixth seed Kaia Kanepi will meet China's Zhu Lin after both won on Monday.

Fifth seed Elise Mertens was a first-round casualty, going down 7-6 (7-4) 6-4 to Ludmilla Samsonova, while Croatian Donna Vekic knocked off seventh seed Mayar Sherif 6-4 6-1.

Six-time major champion Venus Williams played her first singles match in nearly a year but bowed out 4-6 6-1 6-4 to Rebecca Marino. 

Venus Williams will make a long-awaited singles comeback at the Canadian Open next month.

The seven-time grand slam champion has not played a singles match since she lost to Hsieh Su-Wei in the first round at the Chicago Women's Open last August.

But she returned from a leg injury to partner Jamie Murray in the mixed doubles at Wimbledon earlier this month, reaching the second round.

The 42-year-old will be back in singles action in Toronto, where the Canadian Open begins on August 8.

Williams' sister, Serena, will also play in the tournament three weeks before the US Open gets under way.

After being handed a wild card, Venus will join the likes of world number one Iga Swiatek in a strong field.

The American made her debut in the hard-court event as a 15-year-old back in 1995, losing to Sabine Appelmans in the first round.

Martina Navratilova said she was "gutted" to miss Wimbledon's Centre Court centenary celebration after testing positive for COVID-19 on Sunday.

The nine-time champion was absent from a parade of champions, and in a series of posts on social media she explained why she had to sit it out.

Past winners were introduced to the main show court's middle Sunday crowd, with the one-time champions going first, all the way through to eight-time Wimbledon king Roger Federer.

Navratilova would have come out last of all, as the most successful singles player in Wimbledon history, but she was unable to take part. Including doubles, Navratilova won 20 slam titles at Wimbledon.

"Unfortunately I will miss it as I just tested positive this morning," she wrote on Twitter shortly before the ceremony. "Am so bummed!!!! I am gutted I can't be there."

Confirming she had the coronavirus, Navratilova wrote: "Yup, got it here for sure… oh well. So wanted to be on that court with so many champions of our sport."

Asked how she was feeling, the 65-year-old Czech-born American added: "Not too bad so far- wouldn't want to play tennis but ok… fingers crossed."

A host of greats of the game delighted the crowd, with stars of the women's tour including Navratilova's former great rivals Chris Evert and Billie Jean King, along with Margaret Court and Venus Williams, while Federer was joined by a field of fellow men's superstars that included Rod Laver, Novak Djokovic, Stefan Edberg, Rafael Nadal and Andy Murray.

Three-time former champion Boris Becker was another notable absentee, after the German was jailed in April for offences relating to his 2017 bankruptcy. Seven-time winner Serena Williams also missed the event, after her first-round defeat.

Navratilova has been working at Wimbledon during the championships, notably appearing as a member of the BBC broadcast team.
