Serena Williams hinted that she will return to the court at some point in the future after going down in the third round of the US Open against Ajla Tomljanovic on Friday.

Williams, who saved five match points before eventually succumbing in the three-plus hour marathon, gave an emotional on-court interview where she thanked her family, but also highlighted that she felt like she was getting better as the tournament wore on.

When asked conclusively if this was her final US Open, she was non-committal, saying "you never know".

She took the insinuation that she is not finished playing a step further during her sit-down press conference, laying the breadcrumbs for another go around at the Australian Open.

"I don't know [what it would take to play again] – I'm not thinking about that. I always did love Australia, though," she said with a smile.

"But yeah, you know what, I've come a long way since last year at Wimbledon. Just not sure if that was my last moment or not. Making it a different moment I think is much better.

"And it takes a lot of work to get here. Clearly I'm still capable. It takes a lot more than that. 

"I'm ready to, like, be a mom, explore a different version of Serena. Technically in the world I'm still super young, so I want to have a little bit of a life while I'm still walking."

When asked what she thinks her life will be like moving forward, Williams said she is excited to be able to spend more time with her daughter, and that karaoke is on the agenda.

"I'm definitely resting tomorrow, and then probably spending some time with my daughter," she said. "I'm a super hands-on mom. I've been with her almost every single day of her life, minus two days or three days.

"It's been really hard on her, my career. So it will be, you know, nice just to do that and spend some time with her, do things that I never really have done or had an opportunity to do. I have such a bright future ahead of me, I don't know.

"Also, I'm kind of at an advantage because COVID happened. I think everyone shut down for a year, and we kind of got to see what our lives would be like if we weren't playing tennis. 

"Then I got injured last year, so I took off literally a year. So I got to see, again, like, what every day would be like to wake up and not have to go to the gym.

"So I don't know. I think I'm definitely probably going to be karaoke-ing tomorrow."

Touching on how she would like her career to be remembered, Williams said her unique passion and fire is at the forefront.

"I mean, there's so many things to be remembered by," she said. "Like the fight. I'm such a fighter. 

"I feel like I really brought something, and bring something, to tennis. The different looks, the fist pumps, the just crazy intensity. I think that obviously the passion, I think, is a really good word.

"Just continuing through ups and downs. I could go on and on. But I just honestly am so grateful that I had this moment, and that I'm Serena."

Serena Williams was emotional during her post-match interview in the sold-out Arthur Ashe Stadium after her loss to Ajla Tomljanovic in the third round, thanking her family for their decades of support.

Williams ended up going down in a match that lasted three hours and seven minutes, with a 15-minute final game where Williams saved five match points illustrating her fighting spirit down to the last moments.

If this is her final US Open – which she was hesitant to confirm – she will finish with the most main draw wins ever at the tournament with 108, and her 23 grand slam titles are also the most of all-time.

Speaking on the court after Tomljanovic gladly ceded the floor to the legend, Williams turned her attention immediately to her family as she reflected on the journey to this point.

"Thank you, Daddy. I know you're watching," she said as she began to tear up. "Thanks, Mom… I thank everyone that's here, that's been on my side so many years, decades. Oh, my gosh, literally decades.

"But it all started with my parents – they deserve everything. So I'm really grateful for them. These are happy tears, I guess. I don't know.

"And I wouldn't be Serena if there wasn't Venus, so thank you, Venus. She's the only reason that Serena Williams ever existed."

She added: "It's been a fun ride. It's been the most incredible ride and journey I've ever been on, I mean, in my life.

"I'm just so grateful to every single person that's ever said 'go, Serena' in their life. I'm just so grateful."

When asked if this would definitely be her last US Open, Williams was hesitant due to how well she performed, and left the question unanswered.

"I mean, I'm literally playing my way into this and getting better – I should have started sooner this year," she said with a laugh.

"I don't think so, but you never know. I don't know."

Serena Williams' last US Open has come to an end in the third round, going down 7-5 6-7 (4-7) 6-1 against Ajla Tomlanovic on Friday night.

It was a rough start for Williams, getting her serve broken in the first game of the match, but she got it straight back with a break-to-love by utilising her stunning power.

While her power brought her some easy points, it was also her undoing at times, with 16 unforced errors in the first set compared to 10 winners.

After securing another break to go up 5-3, serving for the opening set, Williams could not finish it off, losing the next four games in a row as Tomljanovic found a way to extend points and turn them into grinding rallies.

Not disheartened, Williams came out on fire in the second set, ripping off the first four games, but Tomljanovic again fought back. From 5-2 down, the Australian surged to level things at 5-5 before forcing a tiebreaker.

In the tiebreaker, Williams worked her way to a 5-4 lead, and took two consecutive mini-breaks to send the crowd into raptures and the match to a deciding set.

But where world number two Anett Kontaveit folded in Williams' last match, Tomljanovic did not, responding instantly after having her serve broken in the opening game to take the next five in a row, with a chance to serve things out at 5-1.

The crowd tried to will the living legend back into the contest, saving the first five of Tomljanovic's match points as she refused to go down easily, but she was not able to convert either of her three break point opportunities in a final game that lasted nearly 15 minutes, ultimately going down on the sixth match point.

After a collective groan in the sold-out Arthur Ashe Stadium, the crowd rose to their feet to pay their respect to the greatest women's tennis player of all time in her final outing at the US Open, as she treated the crowd to one more of her famous twirls at the grand slam she has won six times.

Data Slam: Six-time champion Serena leaves behind records that will stand the test of time

Williams finishes her US Open career with the seven more main draw wins than any other player, male or female. Her 108 wins leads Chris Evert (101), Jimmy Connors (98), Martina Navrilova (89) and Roger Federer (89).

She is also one of five players – along with Navrilova, Federer, Rafael Nadal and Novak Djokovic – to spend at least 300 weeks as the world number one, and her 23 career grand slam titles is the most of any player, leading Steffi Graf (22) and Nadal (22).

Coco Gauff admitted it would be a "lifelong dream" to face Serena Williams at the US Open, in what is likely to be the latter's final tournament of a glittering career.

Gauff reached the second week at Flushing Meadows in the women's singles for the first time after cruising to a 6-2-6-3 win over Madison Keys on Friday.

The number 12 seed saw off her fellow American in composed fashion to book her place in the last 16, exceeding her previous best result at the US Open in 2019.

Gauff was largely in control against the number 20 seed Keys to deliver near-flawless performance, chasing a second grand slam final of the year after finishing as runner-up at the French Open to Iga Swiatek.

She will face China's Zhang Shuai in the next round, but when asked if she will watch Williams' match against Ajla Tomljanovic later in the day during her on-court interview, Gauff said she would, adding: "It's been amazing watching Serena's matches so far. I don't know when I'd be due to face her but that's the goal.

"It's been a lifelong dream of mine to do that. Five years ago yesterday I was watching Venus and Serena play here. It's crazy to be on this court now.

"I tried to flex to my friends that I had courtside seats, now I'm on the court!"

Should both remain in the tournament, Gauff and Williams would face each other in the semi-finals.

Gauff also paid tribute to Keys, and to the crowd at Arthur Ashe Stadium, saying: "[The win] means a lot to me... I missed my alarm and was so late. I was here until 9pm last night and lost a doubles match [with Jessica Pegula].

"Kudos to my team, they got me up for it.

"I wasn't sure how the crowd was going to go. We all love Madison... I'm good friends with her off the court, but having support here meant a lot."

Andy Murray has admitted he is "surprised" to still be able to compete against top-level opponents given his injury history.

The 2012 US Open champion exited this year's competition following a third-round defeat to 13th seed Matteo Berrettini, though he did take the tie to four sets.

Having lost the first two sets, Murray fought back to win the tiebreaker in the third but his valiant attempts were ended by the Italian in the fourth, who sets up a round of 16 clash against Alejandro Davidovich Fokina.

Despite the loss, Murray was pleased with his performance at the tournament and encouraged by his ability to still go toe-to-toe with the likes of Berrettini.

"I've got a metal hip. It's not easy playing with that. It's really difficult. I'm surprised I'm still able to compete with guys that are right up at the top of the game," he said after the match.

"Matches like this, you know, I'm really proud that I have worked myself into a position where I'm able to do that. I'm really disappointed that I didn't get over the line today. 

"But I get reminded like 'this is the first time you've made the third round here since 2016'. It's been six years. It's been a difficult six years for me. It's been really hard.

"Although it's the first time I've only made the third round here, I'm really proud of that effort that I put in to get myself back into these positions. So, I'm hoping that in the future I can go further, but considering, I did all right."

Murray went on to explain how things feel differently for him on the court, identifying he cannot move in the same way Rafael Nadal and Novak Djokovic still can.

"A lot of the things feel the same, but obviously I'm just not quite capable of the sort of movement and physicality that I was five, six years ago. I mean, that's pretty obvious. You know, I shouldn't expect to be," he said.

"I think if you watch Rafa and Novak moving around the court now who are similar age, I think they're moving pretty similar to how they were five, six years ago, whereas for me there's obviously been a bit of a drop-off there.

"That can affect you in terms of how you have to play the points. Maybe you just don't track as many balls down as before. Maybe the reach isn't just quite as much as it was.

"But in terms of the shots and everything, there is nothing that is stopping me from hitting the same shots as I did before."

Ons Jabeur has now made it to the second week in all four grand slams after her win over Shelby Rogers at the US Open.

Jabeur, the fifth seed at Flushing Meadows, had previously fallen short of making the second week in the season's final grand slam, having reached the third round in three successive years between 2019 and 2021.

But the Tunisian world number five ended that wait with a 4-6 6-4 6-3 defeat of American Rogers.

Jabeur reached the final at Wimbledon this year, her first appearance in a major showpiece match, but lost to Elena Rybakina.

She has made it to the fourth round of the grand slams six times, having managed quarter-final runs at Wimbledon (2021) and the Australian Open (2020).

Another US Open fourth-round debutant awaits Jabeur in the form of Veronika Kudermetova, who despatched Dalma Galfi 6-2 6-0. 

Kudermetova's victory took just 46 minutes, making it the shortest match of the tournament.

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.

Rafael Nadal feared he had broken his nose after being struck by his own racquet in the second-round win over Fabio Fognini at the US Open.

The Spaniard, seeking a 23rd grand slam title, once again recovered from losing the opening set to claim a 2-6 6-4 6-2 6-1 triumph at Flushing Meadows.

He will now face Richard Gasquet after extending his winning streak at majors in 2022 to 21 matches.

But he will hope the pain from a nasty-looking injury has subsided by then, with Nadal's racquet having bounced off the court and into his nose while he was stretching to make a return in the fourth set.

The world number three needed a medical timeout and treatment, returning with a plaster on his face as the incident ultimately did little to slow his momentum.

"It was just a strong hit," said Nadal. "At the beginning I thought I had broken the nose because it was a shock at the beginning. It was very painful.

"I lost a little bit of the feeling in my head. It was like being a little bit out of this world.

"I don't know, it seems like it is not broken. I am not sure yet. I don't know. I think it's getting bigger and bigger."

For the second match in succession, Nadal had to come from a set behind, having also lost the opener to first-round opponent Rinky Hijikata.

Having struggled to find his rhythm early on, the 36-year-old was pleased that his persistence paid off.

"I'm happy after a terrible start. I don't understand yet how I started that bad because the feeling before the match was good," he said, the win having secured his spot at the ATP Finals for a 17th time.

"But these kind of things sometimes happen, so you need to accept and keep going. That's what I did.

"I'm lucky that Fabio made some mistakes and I was able to start putting some balls in and finish the match playing obviously better, much better."

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.

Alize Cornet is through to the third round of the US Open after defeating Katerina Siniakova 6-1 1-6 6-3, making it the first time she has been beyond the second round of every grand slam in a single season.

Cornet, who defeated reigning champion Emma Raducanu in straight sets to begin her campaign, was terrific with her return game early on, winning 54 per cent of the points off Siniakova's serve in the opening set.

Three double faults for Cornet and the inability to win a single point off her second serve led to a quick second frame for Siniakova, but she steadied in the decider, becoming the first Frenchwoman to win her opening two rounds of each grand slam in a season since Caroline Garcia in 2017.

Cornet has now won five of her past six matches and should be considered a threat given her victory over world number one Iga Swiatek at Wimbledon in July.

She will play the winner between Danielle Collins and Cristina Bucsa in her next match.

Iga Swiatek suggested there has been a lack of leadership at the top of tennis in how to deal with Russia's invasion of Ukraine after Victoria Azarenka was shunned by Marta Kostyuk at the US Open on Thursday.

Ukrainian Kostyuk elected not to shake hands with Azarenka following a second-round defeat at Flushing Meadows, instead merely tapping rackets.

That came after Kostyuk criticised the Belarusian for participating in a charity match for Ukraine, before the United States Tennis Association announced she would no longer be involved.

Belarus maintains close ties with Russia and has been under sanction from western nations for supporting Vladimir Putin after the Russian invasion of Ukraine in March.

Both situations led to a frosty atmosphere following the conclusion of the tie, which Azarenka won 6-2 6-3.

Asked if anything could be done to address tensions between players on the tour, world number one Swiatek, who booked her place in the third round with a 6-3 6-2 win over Sloane Stephens, said: "Well, basically I think it's already too late. I mean, it's never too late, you know, but I think the best time for ATP or WTA to do anything was when the war started, and where the tension was pretty big in the locker rooms.

"I think right now it's already pretty messed up, and maybe next time it's gonna be easier for us to handle it if somebody is going to guide us and somebody is going to even arrange some meetings between players and showing that we should be united.

"Even though there are countries who are invading other countries, we are tennis players. It's sad but it's not our fault that it's happening. Yeah, I think it would be much, much easier at the beginning to do that.

"Right now, it's kind of too late to fix that. But I think it's just in between players and their personal relationships how you're going to handle it and how you're going to communicate to each other.

"But from my case, right now it's easy to say that maybe there was lack of leadership, but at that time I didn't know what to do either. But there are smarter people than me, so they should kind of have an idea."

Victory over Stephens means Swiatek has now won 52 matches in 2022. The last players with more WTA-level wins in a single campaign were Ash Barty (57) and Kiki Bertens (55) in 2019.

Serena Williams is dominating the headlines, though, in what is likely to be her last tournament before retirement – a situation Swiatek is more than happy with. 

Asked if she felt like she was flying under the radar, Swiatek said: "Maybe a little bit, yeah, for sure. You can see the difference than on Roland Garros and on Wimbledon when I came back after winning Roland Garros.

"But I would say it doesn't really matter for me. If I'm going to play well and if I'm going to do my work on court, I know I will be fine in terms of everything that's going around.

"But, yeah, Serena totally deserves it and it's pretty obvious for me that she's going to be in the spotlight in this tournament. That's kind of her time right now. I'm just playing and focusing on that, and that's the most important thing for me."

Swiatek will face Lauren Davis in the next round after the American beat Ekaterina Alexandrova 0-6 6-4 7-6 (10-5). 

Victoria Azarenka was not concerned by being shunned by Marta Kostyuk at the US Open, adding that she has tried to contact the Ukrainian throughout the year.

Kostyuk elected not to shake hands with Azarenka following a second-round defeat at Flushing Meadows, instead merely tapping rackets.

That came after Kostyuk criticised the Belarusian for participating in a charity match for Ukraine, before the United States Tennis Association announced she would no longer be involved.

Belarus maintains close ties with Russia and has been under sanction from western nations for supporting Vladimir Putin after the Russian invasion of Ukraine in March.

Both situations led to a frosty atmosphere following the conclusion of the tie, which Azarenka won 6-2 6-3.

"Well, I wasn't surprised. I don't believe that making a big deal out of it is important. I always shake hands with my opponents. I had the same situation with [Dayana] Yastremska in Washington. It is what it is. I just move on. I cannot force anybody to shake my hand. It's their decision," Azarenka said in a press conference.

Asked if she had spoken to Kostyuk, Azarenka added: "I've offered many times through WTA, because I believe that there is a sort of sensitivity. I've been told that that's not a good time.  

"I don't have, or I never had a close relationship with Marta. I obviously knew who she is, but I've never practiced with her. I've never really had conversation with her.

"So in March when everything happened, I reached out to all the players that I personally know and I still have a good relationship with and, you know, I don't feel that forcing myself to speak to somebody who maybe doesn't want to speak to me for different reasons is the right approach. But I offered."

Kostyuk was asked about the decision not to shake hands and explained her reasons, saying she believed it was not "the right thing" in the current climate.

"I just don't think it's the right thing to do in the circumstances I'm in right now," she said.

"We had a great match, don't get me wrong. She's a great competitor, I respect her as an athlete but that has nothing to do with her being a human being."

Victoria Azarenka has played down the significance of being shunned by Marta Kostyuk at the US Open, adding that she has tried to contact the Ukrainian throughout the year.

Kostyuk elected not to shake hands with Azarenka following a second-round defeat at Flushing Meadows, instead merely tapping rackets.

That came after Kostyuk criticised the Belarusian for participating in a charity match for Ukraine, before the United States Tennis Association announced she would no longer be involved.

"We had a great match, don't get me wrong. She's a great competitor, I respect her as an athlete but that has nothing to do with her being a human being."

Iga Swiatek is through to the third round of the US Open after securing a routine victory against Sloane Stephens at Arthur Ashe Stadium.

Stephens, who won the 2017 US Open, struggled to keep up with Swiatek as the latter showed her quality on Thursday to win 6-3 6-2.

The number one seed set the tone early by breaking her 29-year-old opponent, and though Stephens responded by breaking straight back, she lost her own service again immediately after.

Swiatek almost broke for a third-straight time but Stephens was able to rescue herself from 15-40 down in the fifth game of the match, though it just delayed the inevitable as the Pole sealed the first set after her opponent hit a backhand effort down the line too long.

There was little sign of a momentum shift as Swiatek broke twice more and raced to a 4-0 lead in the second set.

Though Stephens was taking several games to deuce, Swiatek showed her class to edge over the line in most of them and although the American made the score more respectable with two service holds, it was not enough.

Swiatek confirmed a routine victory with a service hold to love, and will now face another American, Laura Davis, in the next round.

Data Slam: Swiatek's impressive 2022 numbers grow and grow

Swiatek has now won 52 matches in 2022. The last players with more WTA-level wins in a single campaign were Ash Barty (57) and Kiki Bertens (55) in 2019.

The way she is playing at Flushing Meadows, it would not be a surprise to see her overtake Bertens before the end of the tournament.

Serena Williams revealed how Tiger Woods encouraged her to return to tennis for one last glory mission after she powered into round three of the US Open.

Golf great Woods was on his feet and rapturously celebrating as Williams beat number two seed Anett Kontaveit on Wednesday night in New York.

He had been invited to sit in Williams' player box and shared conversations with Venus Williams as they watched Serena push past Kontaveit with a dynamic display, coming through 7-6 (7-4) 2-6 6-2 on Arthur Ashe Stadium.

It was remarkable from the 40-year-old on court as she found an extra gear for the deciding set, teeing up a clash with Australian world number 46 Ajla Tomjlanovic.

Williams has firmly indicated this will be her final tournament before retirement, and a host of stars have come out to watch her in action, with former US president Bill Clinton in the crowd for her first-round match.

Woods, actress Zendaya and film director Spike Lee were among those watching the Kontaveit match, and Williams suggested afterwards that she and 15-time major champion Woods had helped each other with their respective comebacks.

At this time last year, Williams was sidelined by a leg problem sustained at Wimbledon, while Woods was recovering from the serious leg injuries he suffered in a car crash.

"He's one of the reasons I'm here, one of the main reasons I'm still playing," Williams said. "We talked a lot. He was really trying to get me motivated.

"There's a few people, but we were like, 'Okay, we can do this together'.

"It was good, because I didn't know what I wanted to do. I was just lost, so many questions. When you can rely on someone like that, I mean, my goodness, he's Tiger Woods, it was really helpful to get clarity."

What Williams is wary of at this stage is raising her own expectations.

She was charmingly dismissive of an on-court question when asked if she was surprised by how well she was performing.

As far as Williams is concerned, she has proven countless times she is the greatest player, certainly of her own era, so even with limited preparation she backs herself.

But thinking too intently about winning majors may have been costly in recent years, with Williams having lost her last four grand slam finals to remain on 23 singles titles, one short of Margaret Court's all-time record.

"I cannot think that far," when asked about the prospect of winning the tournament. "I'm having fun and I'm enjoying it. Honestly, I've had so many tough matches the last I don't know how long that I just feel like just being prepared for everyone that I play is just going to be really, really difficult. Get through those moments."

In typical Williams fashion, she has danced around the subject of retirement since writing in Vogue in early August she would be "evolving away from tennis".

She spoke of wanting to "relish these next few weeks" in the magazine article, and so far at Flushing Meadows she is savouring every moment.

Serena and Venus were due to play doubles on Thursday, again on the Ashe Stadium court, with more fanfare expected.

"I think I've mostly been kind of blocking everything out, but then at the same time I've been embracing a little bit of it, because I also want to enjoy the moment," WIlliams said.

"I just feel like I have had a big red X on my back since I won the US Open in '99. It's been there my entire career, because I won my first grand slam early in my career.

"But here it's different. I feel like I've already won, figuratively, mentally. It's just pretty awesome the things that I've done."
