Three-time grand slam champion Angelique Kerber has announced she is pregnant and will miss the US Open as "two against one just isn't a fair competition."

The former world number one on Wednesday revealed she will not be around on the WTA Tour "for a while", as she is expecting her first child.

Kerber, 34, says she is "nervous and excited" by the "new path" she is heading in.

The German posted on Instagram: "I really wanted to play the @usopen but eventually I decided that two against one just isn't a fair competition.

"For the next months, I will take a break from traveling the globe as a tennis player but then again, I believe it’s for the best possible reason! I will miss all of you.

"New York has often been a turning point in my career and it feels like this year will be no different in some way! From restarting my career in 2011 to winning the title in 2016 and becoming #1 in the world… the @usopen have a special place in my heart and I wish I could have said goodbye to all of you on court before not being around on tour for a while.

"Being a professional athlete means everything to me but I'm grateful for the new path I'm heading to. To be honest, I'm nervous and excited at the same time. Thanks for your continued support - it means everything to me "

Kerber's announcement came just five days before the US Open gets under way at Flushing Meadows.

The left-hander was crowned champion in New York six years ago after also winning the Australian Open in 2016 and she went on to take the Wimbledon title in 2018.

Retiring legend Serena Williams has indicated she "will always have some sort of involvement" in tennis as she prepares for the US Open, in what will be the final Grand Slam of her career.

The 40-year-old has won 23 major singles titles, while also adding 14 doubles championships in a brilliant career, but will be hanging up her racquet after she plays in the tournament she has won six times.

Her first time lifting the US Open trophy came in 1999, but even after spending over two decades at the top level of the sport, Williams says she will continue to be active in tennis.

"I will never retire from something I absolutely love," the American told Meghan Markle on the Duchess' new Spotify podcast.

"I will always have some sort of involvement in it. Maybe not professionally, but I will always want to be involved in some form in tennis. Obviously, I’ve retired professionally, but it’s also an evolution."

Williams also outlined her plans for the future, adding: "I really want to expand my family, and you know I’ve been putting it off for so long.

"As a woman, there’s only so long you can put that off and other people out there, other men out there, can continue to play. My best is being a mom; I think I can do really good at that."

Fellow tennis legend John McEnroe has heaped praise on Williams ahead of the tournament at Flushing Meadows, commenting: "The way that she moves the needle when she plays, it's like Tiger Woods and golf.

"You can look at the accomplishments, she has the Grand Slam victories. Off the court, I know that she's had a lot of difficulties in her life that she talks about in her own documentaries, but she has come out the other end as this icon, global superstar.

"Her story alone, what she represents as someone who's an African-American girl who came from a tough situation, and became the greatest player that ever lived. What that represents for us, and maybe around the world, is an opportunity that it can happen to anyone potentially."

John McEnroe has called Novak Djokovic's potential absence from the US Open over his vaccination status a "joke".

The United States does not currently allow those who have not received the COVID-19 jab into the country, putting the unvaccinated Djokovic in real danger of missing this year's edition of the tournament he has won three times.

The Serb has already missed the Australian Open this year because of his lack of vaccination, while also missing tournaments at Indian Wells in California, as well as the Rogers Cup in Canada.

He did however win his 21st Grand Slam at Wimbledon earlier this year, and McEnroe believes Djokovic should be allowed to play at Flushing Meadows as he chases down Rafael Nadal for the most Grand Slam titles in history.

Ahead of the tournament in New York, McEnroe told reporters: "No, I don't think it's fair. I think it's a joke.

"I would have had the vaccine and gone and played but he's got very strong beliefs and you have to respect that. 

"At this point, in the pandemic, we're two and a half years in, I think people in all parts of the world know more about it, and the idea that he can’t travel here to play, to me is a joke."

On whether Djokovic's decision not to get the vaccine could affect his competition with Nadal and Roger Federer to become the most decorated male player ever, McEnroe replied: "That's the question that we all want to know the answer to.

"Obviously, Rafa Nadal has benefited from that. These three guys are already above everyone else. So, it makes it extremely interesting to see these two go at it and then you think of Roger Federer but he's been hurt for a while."

However, McEnroe believes Djokovic can overcome his vaccination status to win more titles, adding: "Who's to say [Djokovic] can't do it for another couple of years?

"Let's say that he wins three or four more. That's not impossible, by any means. Despite this, he can still get to 25. I think it's made it more complicated to do it because that has to wear on you mentally.

"Training this past month or six weeks not knowing whether he's going to play, that's going to put a strain on you mentally just as it was when he got thrown out of Australia. I think it took him three, four months to get his head right."

The clock is ticking on Novak Djokovic's prospects of playing at the US Open, two days out from the draw at Flushing Meadows.

Wimbledon champion Djokovic, who lost to Daniil Medvedev in last year's final in New York, has his route to the United States blocked by red tape at present.

US authorities are refusing to allow unvaccinated foreign visitors to enter the country, and barring a change of policy on that front, his hopes appear forlorn. Djokovic, a three-time US Open champion, has refused to accept any COVID-19 vaccine.

The United States Tennis Association (USTA) has pledged to adhere to government rulings surrounding coronavirus protocols, despite including Djokovic on the US Open entry list last month.

He remains on that list for now, but there was an indication that the US Open may not be expecting to see Djokovic when a promotional poster was revealed this week that featured four top women players and four leading men.

The men selected were defending champion Medvedev, 22-time grand slam winner Rafael Nadal, Australian Nick Kyrgios and Spanish teenager Carlos Alcaraz. All were archive pictures, so Djokovic could easily have been selected for the advertising campaign.

His exclusion prompted an angry response on social media from some fans of the 35-year-old Serbian, with one saying it would be "a failed tournament if he doesn't participate in it".

The US Open draws are due to take place on Thursday ahead of the start of the tournament on Monday.

Leading players are already assembling on site, with Medvedev, Serena Williams, Nadal, Alcaraz, Simona Halep and Andy Murray among those with practice sessions booked in for Tuesday.

For Djokovic to be allowed into the United States, it appears he would require a sudden change of entry rules from law-makers, or he would have to be considered suitable for an exemption.

In late July, he said he was "preparing as if I will be allowed to compete"; however, he has not been able to travel for the build-up tournaments.

On Instagram, Djokovic's last tennis-related post came on Monday night as he sent a congratulatory message to shock Cincinnati champion Borna Coric, telling the Croatian: "Bravo king! Totally deserved. All the effort and patience paid off. Go ahead and good luck."

Djokovic was not allowed to play at the Australian Open at the start of the year, when issues surrounding his visa ended with him being deported from Melbourne on public health grounds due to not taking the vaccine.

American great John McEnroe told Tennis 365 in July it was "crazy" that Djokovic should have to miss the US Open and called for a solution to be found.

The current entry rules in the United States were not in place when Djokovic was toppled by Medvedev in last year's men's singles final, ending his hopes of a calendar Grand Slam.

World number two Alexander Zverev has withdrawn from the US Open as he recovers from ankle surgery.

The German went under the knife after tearing all three of the lateral ligaments in his right ankle during his French Open semi-final against Rafael Nadal.

Zverev will not make his comeback at the final grand slam of the year in New York, as his withdrawal was announced on Monday.

The 25-year-old reached his only major final at Flushing Meadows two years ago, losing to Dominic Thiem.

Zverev stated after his operation that surgery was "the best choice" to ensure his ligaments heal properly and he could return to competition "as quickly as possible."

The US Open gets under way next Monday, with doubts remaining over whether Novak Djokovic will be able to play due to the 21-time grand slam champion opting against receiving a coronavirus vaccine.

The prize pot for this year's US Open will top $60million for the first time in the competition's history, event organisers have announced.

The 2022 edition at Flushing Meadows gets under way on August 29 and runs for just under two weeks.

It was revealed on Thursday that $60m will be up for grabs, topping the previous record of $57.5m from last year, with both singles champions to receive $2.6m.

Players will be given $80,000 for making the main draw and $121,000 should they make it to the second round. Runners-up in the singles will pocket $1.3m.

In the doubles, the champions will receive $688,000, the runners-up $344,000 and the semi-finalists $172,000.

Emma Raducanu admitted she has been "too tense" in recent defeats and is aiming to play more freely as she prepares to defend her US Open title.

Raducanu has struggled to follow up last year's shock win at Flushing Meadow, but she appears to have hit form at just the right time.

The 19-year-old has beaten both Serena Williams and Victoria Azarenka in straight sets during this week's Western and Southern Open in Cincinnati, dropping just four games against Williams and two against Azarenka.

Her win against Azarenka on Wednesday was just Raducanu's third career victory against a top-25 opponent, after beating Belinda Bencic and Maria Sakkari on her way to winning last year's US Open.

Speaking after her win against the Belarusian, Raducanu said: "I think I have tried a lot of things, and this year I think some matches, I have lost a lot of matches from leading situations and probably just played too tense.

"I think that I just need to swing, and I just said that these two tournaments, or this tournament especially, I'm just going to swing freely and take that and see what happens."

Raducanu also said she will wait until after the tournament to reflect on beating two multiple grand slam champions with relative ease.

"I think after the tournament I actually have to take a step back and be like, 'Look, you just beat two unbelievable champions'," she said. "It's a pretty good achievement. You know how difficult the wins are to come by."

The number 10 seed will face seventh seed Jessica Pegula in the third round in Cincinnati on Thursday.

Taylor Fritz believes there would be no "harm" in Novak Djokovic competing at the US Open, although the American admits he is conflicted about whether he should be allowed.

Wimbledon champion Djokovic has his route to Flushing Meadows blocked by red tape at present, with the United States refusing to allow unvaccinated foreign visitors to enter the country.

US tennis authorities have pledged to adhere to government rulings surrounding COVID-19 protocols, despite including Djokovic on their entry list.

For Djokovic to be allowed into the United States, it appears he would require a change of policy from law-makers, or he would have to be considered suitable for an exemption.

Among those who would be eligible for such an exemption are "persons whose entry would be in the national interest".

With 21 grand slam titles, Djokovic sits second on the men's all-time list behind Rafael Nadal, who has 22 victories at the majors. 

And Fritz, ranked 13th in the world, said that while the situation is complicated, there is part of him that thinks Djokovic should be allowed to take part in the competition that starts in under a fortnight.

"It's tough," he said. "I think on one side of it, I think it's tough to make certain exceptions to the rules for certain people.

"I don't know how I feel about that, but then, at the same time, we're not the most COVID-safe country in general with how we are doing things.

"So it does seem like, what's the harm of letting the best player in the world come play the US Open?

"But like I said, at the same time, it's conflicting, because I don't know how I feel about making special exceptions just for one person because of who they are.

"So I see both sides of the argument, to be honest. It's tough to differentiate, obviously. It's good for every player if Novak is not in the draw."

Serena Williams is "one of the greatest of all time", says fellow tennis legend Rafael Nadal as the 23-time grand slam winner prepares to hang up her racquet.

The 40-year-old, one of the most decorated players in the history of the sport, signalled her intent to "evolve away" from the game in an interview with Vogue Magazine earlier this month, hinting at her retirement following the U.S. Open in September.

With just shy of two-dozen grand slam singles titles, Williams trails only Margaret Court for the all-time record of 24 crowns, and could equal her in her farewell appearance.

Nadal, meanwhile, lies one behind her after victory in the Australian Open and French Open this year took him clear of Novak Djokovic and Roger Federer to 22, though the former's win at Wimbledon has seen him close the gap again.

The duo are set to feature at this week's Western and Southern Open, where Williams will face incumbent U.S. Open champion Emma Raducanu, and the Spaniard - who will mark his return from injury - has nothing but praise for his fellow giant of the game.

"She is one of the greatest sports [people] of all time," he stated. "I feel lucky to share a tour for a long period of time with her.

"Of course, from a selfish point of view, it's sad that she's leaving the tour but, on the other hand, we can't thank her enough for all the things that she did for our sport.

"I think she's an amazing inspiration for a lot of people around the world and I think she deserves to choose whatever works for her better at this stage of her life.

"So I wish her all the best. Hopefully, we can keep seeing her around the tour because I always believe that our sport, or the sport in general, is bigger and better when legends are around and she is a legend.

"Hopefully, we can enjoy her in a different way around the tour."

Nadal was forced to withdraw ahead of the Wimbledon semi-finals earlier this year with an abdominal tear, and now faces a potentially nervy run through to the U.S. Open in terms of fitness.

But the 36-year-old is cautiously optimistic, adding: "I hope to be ready. That's what I'm trying to do. Try to be a little more conservative, but I hope I can be ready to play.

"Of course, I need some more days to analyse how things are going in terms of abdominal feeling.

"But things are going well for the moment, so hopefully I can manage to be ready. I'm excited. I want to play tennis again on the tour. I'm having a good season, I'm enjoying it, so I want to enjoy this week in Cincinnati."

Serena Williams' decision to begin winding down her tennis career has saddened world number one Iga Swiatek and Belinda Bencic, who defeated the 40-year-old on Wednesday.

Williams announced on Tuesday that she is about to retire, saying "the countdown has begun" as she looks to "move in a different direction".

While the 23-time singles grand slam champion did not put a specific timeline on her remaining days in tennis, her comment about looking for new challenges after "these next few weeks" suggests the US Open – which she has already been included on the entry list for and starts at the end of August – will be her swansong.

That announcement came on the back of Williams' first singles win in 430 days, a defeat of Nuria Parrizas-Diaz at the Canadian Open in Toronto, but she was subsequently eliminated by Bencic on Wednesday, when the reality of her farewell tour set in.

Williams failed to hold back the tears as she said goodbye to the Toronto crowd for the last time as a player, and Bencic herself could not help feeling a little overcome

She said: "It was definitely very special. I think it was more than just the usual tennis match, also just really exciting, and also a little bit overwhelming for me, of course.

"[It's] great, I can be part of her career and her story and this was just really nice and I'm just really appreciative and honoured to play her so many times, and also here in Toronto.

"I mean, she's really the greatest of all time, so it's really exciting. I could have been on the court against her so many times and even today I really enjoyed it a lot. It was sometimes like a pinch me moment again."

Williams finished five different calendar years as the highest-ranked player in the world, a record only Steffi Graf and Martina Navratilova can better.

Swiatek, the current world number one, looks to be the best-placed of the next generation to challenge that achievement, though she recognises a degree of fortune in not having to face Williams at the peak of her powers.

"Well it's always pretty sad when you see such a career coming to an end, but on the other hand she's a legend and I feel like she's done so much," Swiatek added.

"It's really amazing. I'm pretty sad that I wasn't able to play against her and experience that her being the strongest one on tour, but on the other hand, I would be losing against her if I played [her at] that time, so that's fine!

"But she's a legend and everything that she has done on court and off court, she's basically a superstar and the way she handled playing tennis and business and also being a mother, it's mind-blowing. So I'm pretty sure that she's going to have a great second part of her career."

The day after declaring her impending retirement, Serena Williams was full of emotion and admitted it had been a "pretty interesting 24 hours" for her.

Williams revealed on Tuesday in an article in Vogue that "the countdown has begun" for her retirement with this month's US Open set to be the 23-time major winner's last tournament.

The 40-year-old was knocked out of the Canadian Open on Wednesday by Belinda Bencic 6-2 6-4 and spoke after the match for the first time publicly since declaring her intention to retire.

"It was a lot of emotions obviously," Williams said during the on-court post-match interview.

"I've loved playing here [Toronto], I've always loved playing here. I wish I could have played better but Belinda played so well today.

"It's been a pretty interesting 24 hours."

Williams, who won the first of her 23 Grand Slam titles way back in 1999 at the US Open, was emotional about the reception from fans to her announcement.

"It's just been so memorable," Williams said.

"Like I said in my article, I'm terrible at goodbyes. But goodbye, Toronto."

Williams has already been named on the entry list for the US Open, which starts at Flushing Meadows at the end of August.

The former world number one had claimed her first WTA singles win in 430 days on Monday when she defeated Nuria Parrizas-Diaz in preparation for her US Open farewell.
