Naomi Osaka beat Lucia Bronzetti 6-3 6-2 in the first round of the China Open on Wednesday, in her first match under Serena Williams' former coach Patrick Mouratoglou.

Osaka was returning to the Beijing event for the first time since triumphing there in 2019, and she rallied after going a break down in the first set, ultimately winning comfortably.

The four-time major champion smashed 30 winners to Bronzetti's seven in the one-hour, 23-minute contest, teeing up a second-round clash with Yulia Putintseva.

Speaking after her win, she admitted she had harboured doubts over Mouratoglou initially but was now convinced she has found the right coach.

"I think the fact he was Serena's coach made me want to avoid him," she said. This isn't rude because I found out it's not true, but I didn't know if he was a good coach or he just coached Serena!

"Then I met him, talked to him, worked with him on the court. He absolutely is a really good coach. I'm really glad that he's taking this project on, as well." 

Data Debrief: Osaka's hard-court success

Osaka's victory means she now holds a 72.3% win percentage on hard courts at WTA 1000 events and grand slams (102 wins, 39 defeats).

Only three active players have a better such win ratio; Iga Swiatek (78.3%), Victoria Azarenka (75.5%) and Aryna Sabalenka (73.8%).

Iga Swiatek cruised into the fourth round of the US Open, crediting a chat with Serena Williams for her straight-sets win over Anastasia Pavlyuchenkova.

The world number one prevailed 6-4 6-2, without facing a break point in Arthur Ashe Stadium on Saturday.

Swiatek needed just 95 minutes to get into the next round, setting up a meeting with Liudmila Samsonova.

A four-game winning streak in the second set put the game beyond doubt, earning her a third straight-sets victory of the tournament so far.

"It was nice that Serena [Williams] approached me [in the players' gym], because I wouldn't, for sure, find courage to do that," Swiatek said.

"Even though we met before and for a couple of years we have been on the same sides and on tour together, she's still star-striking for me.

"It inspired me, and it gave me a positive kick.

"It's not like my tennis is perfect, but it is weird because I have been number one and winning tournaments, I feel I need to work on some stuff."

Data Debrief: Total dominance

Swiatek, who won at Flushing Meadows in 2022, is into the fourth round at a grand slam for just the second time this year, having failed to reach it at the Australian Open and Wimbledon.

It is the 16th time she has reached that stage in her 23rd main draw appearance - only Coco Gauff has also reached the fourth round in over half of her main draws at grand slams among active players.

The Pole looks to be in fine form though, with this victory lifting her winning percentage to 82.8% (82-17) in women's singles matches at grand slam events - she is now up to 11th on the all-time list in the Open Era, surpassing Martina Hingis.

Iga Swiatek clinched the Madrid Open title after downing defending champion Aryna Sabalenka in a gruelling final.

In a rematch of last year's final, the top two players in the world did battle in thrilling fashion on Saturday, with Swiatek eventually prevailing 7-5 4-6 7-6 (9-7) after three hours and 14 minutes on court.

It marked Swiatek's first title in Madrid, and the Pole had to do it the hard way, saving three championship points before finally coming out on top in the tie-break, which she sealed with her second championship point when Sabalenka sent a backhand long.

This victory means Swiatek, who has won the French Open on three occasions, has now won every European clay court tournament at WTA 500 level or higher.

It was also Swiatek's seventh victory over Sabalenka, from what was their 10th meeting.

Data Debrief: Clay queen Swiatek rolls on

Swiatek has now won her past seven WTA Tour-level finals, since the defeat to Sabalenka in Madrid last season, while only Elena Rybakina can match her haul of three titles so far in 2024.

This was the longest singles final of the year so far on the WTA Tour, while it was the fourth show-piece match in a WTA 1000 event to be decided by a third set tie-break.

Since the format’s introduction in 2009, only Serena Williams (13) and Victoria Azarenka (10) have more WTA 1000 titles than Swiatek, whose tally of nine equals the efforts of Simona Halep and Petra Kvitova.

Meanwhile, of players to have made at least 10 appearances at clay court tournaments, only Chris Evert, Margaret Court and Steffi Graf have a higher ratio of victories in the Open Era than Swiatek (8/18).

In fact, Swiatek has now claimed a tournament victory in 31 per cent (9/29) of the WTA 1000 main draws she has entered, the highest percentage of any player since the format’s introduction in 2009.

Serena Williams withdrew from the Australian Open on January 5, 2018 and announced she would not defend the title she won while pregnant.

The American had kept secret the fact she was expecting her first child as she swept to a 23rd grand slam title in 2017, defeating sister Venus 6-4 6-4 in the final.

Williams gave birth to daughter Alexis Olympia in September of the same year and ultimately decided to delay her return to the big stage.

Williams had played an exhibition match on December 30 in Abu Dhabi against Jelena Ostapenko, testing out her fitness in a 6-2 3-6 10-5 defeat, and that prompted her decision to sit out the new year’s first grand slam.

She said: “After competing in Abu Dhabi I realised that, although I am super close, I’m not where I personally want to be.

“My coach and team always said only go to tournaments when you are prepared to go all the way.

“I can compete, but I don’t want to just compete, I want to do far better than that and, to do so, I will need a little more time.”

Australian Open tournament director Craig Tiley said: “The true champion Serena is has been demonstrated in the Herculean efforts she has made over the past few months in her desire to play the Australian Open.

A post shared by Serena Williams (@serenawilliams)

“Serena transcends the sport in the way she approaches all aspects of her life and consistently gives her all in everything she does.

“It was never going to be good enough for her to just compete, she wants to give herself the best chance to win.

“I’ve been in constant contact with Serena and her team and know this is why she has pushed it and pushed it until the eleventh hour to make her final decision.

“We all wish her the very best and I look forward to seeing her back on court this year, and can’t wait to welcome her back to the Australian Open in 2019.”

Williams went on to reach four more grand slam finals but did not win another title before retiring in 2022.

Coco Gauff says Serena and Venus Williams are the reason she has won the US Open.

American teenager Gauff picked up her first grand slam title at her home major, coming from a set down to beat Aryna Sabalenka 2-6 6-3 6-2.

Gauff’s father Corey used to take his young daughter to Flushing Meadows to watch the Williams sisters in action.

And the gilded duo, with eight US Open titles between them, inspired an eight-year-old Gauff, filmed dancing in the stands inside Arthur Ashe Stadium, to follow in their footsteps.

“It’s crazy. I mean, they’re the reason why I have this trophy, to be honest,” said Gauff.

“They have allowed me to believe in this dream, you know, growing up. You know, there wasn’t too many black tennis players dominating the sport.

“It was literally, at that time when I was younger, it was just them that I can remember.

“Obviously more came because of their legacy. So it made the dream more believable. But all the things that they had to go through, they made it easier for someone like me to do this.

“I mean, you look back at the history with Indian Wells with Serena (when she was booed in 2001), all she had to go through, Venus fighting for equal pay.

“Yeah, it’s just, like, it’s crazy and it’s an honour to be in that same kind of line-up as them.”

Gauff’s day of destiny saw her became the first American teenager to triumph at Flushing Meadows since Serena Williams in 1999.

The latter’s final farewell to tennis at the same championships last year left a colossal void in tennis in the US.

So it felt entirely appropriate that Gauff, the heir apparent to the 23-time grand slam winner, stepped into her shoes 12 months later.

Gauff used her acceptance speech to thank “the people who didn’t believe in me”.

The 19-year-old was at a low ebb after losing in the first round at Wimbledon, but she has since won 18 of her past 19 matches and picked up three titles, including the big one in the Big Apple.

“I would say for sure a little bit after the Wimbledon loss, honestly I just felt people were like, ‘oh, she’s hit her peak and she’s done’. It was all hype,” she added.

“I see the comments. People don’t think I see it but I see it. I’m very aware of tennis Twitter.

“Honestly after that, I was like, OK, I have a lot of work to do. So I think this means a lot to me. I wish I could give this trophy to my past self so she can be, like, all those tears are for this moment.”

Coco Gauff became the first American teenager since Serena Williams in 2001 to reach the semi-finals of the US Open.

The 19-year-old dropped just two games as she blitzed Jelena Ostapenko 6-0 6-2 inside Arthur Ashe Stadium.

Latvian Ostapenko, the 20th seed, had blown the women’s draw wide open when she knocked out defending champion and world number one Iga Swiatek in round four.

But she was unable to take advantage of her own handiwork as Gauff raced away with the first set in only 20 minutes.

Ostapenko made more of a contest of it in the second set, finally managing to hold serve at the fifth attempt.

But Gauff completed the job in an hour and eight minutes to reach the last four of her home grand slam for the first time.

“It feels great, I’m so happy,” she said. “Last year I lost in the quarter-finals and I wanted to do better. There’s a long way to go but I’m happy and ready to go back to work.

“Honestly, I didn’t feel comfortable the whole match, even on match point. I know the game she plays. It’s really tough against her – you can’t really be aggressive. She’s a top player and she’s had a great tournament.

“There’s a saying in basketball that ‘defence wins games’. It doesn’t always work in tennis but today that was the case.”

Gauff will face the winner of Tuesday night’s match between Sorana Cirstea and Karolina Muchova in the last four.

Lionel Messi began his Inter Miami career with a bang as the Argentinian magician ended his debut with a stunning free-kick winner against Cruz Azul deep in stoppage time.

Seven months on from lifting the World Cup, the eyes of the footballing world were trained on Florida as the seven-time Ballon d’Or winner made his eagerly anticipated first appearance.

Messi’s Miami debut has been years in the making and proved well worth the wait.

After Robert Taylor’s excellent opener was cancelled out by Uriel Antuna, the 36-year-old struck at the death to send DRV PNK Stadium delirious and seal an unforgettable 2-1 Leagues Cup win.

It was the dream end to an evening that attracted fans of all ages in ‘Messi 10’ shirts, with stars like LeBron James, Serena Williams, Kim Kardashian and, of course, David Beckham among those in the sold-out, expectant crowd.

The proud Miami co-owner watched on from a box next to the dugout, where the early exchanges made for uncomfortable viewing as Miami looked every bit the Eastern Conference’s bottom side.

Inter rode out that early storm and took the lead just before the break as Taylor’s exquisite low strike went in off the post to Messi’s delight.

The forward was cheered throughout and received a rapturous reception when brought on in the 54th minute, taking the armband as Sergio Busquets also came on for his debut.

Jordi Alba has also signed up to join their former Barcelona boss Tata Martino in Miami, but there remains work to do and that was clear as Cruz Azul deservedly levelled through Antuna.

The Mexicans could easily have won it as the clock wound down, but this was Messi’s night.

The 36-year-old won a free-kick deep in stoppage time and there was an air of inevitability before he sent the resulting set piece into the top left-hand corner as fireworks filled the air.

This was a huge moment for Major League Soccer and momentous night for North American football, 48 years on from Pele’s New York Cosmos bow and 16 years to the day since Beckham made his LA Galaxy debut.

Messi’s name was chanted by excited fans through a match that the hosts began in ragged fashion as Cruz Azul toyed with the hosts. Carlos Rotondi sent an early effort off the post during that early barrage.

Miami offered precious little in return but – following a break to deal with Ian Fray’s nasty-looking injury – a moment of magic lit up the game.

Robbie Robinson’s diagonal pass found Taylor high and wide on the left, with the Finland international cutting inside, making space and slamming a low right-footed shot in off the far post.

Messi was on his feet celebrating and soon gearing to come on, with the big moment eventually arriving in the 54th minute.

Benjamin Cremaschi made way as the Argentina skipper jogged on to a huge roar and took the captain’s armband. Former Barca team-mate Busquets and Josef Martinez joined him as part of an exciting triple substitutions.

There was an electric atmosphere whenever Messi touched the ball but the Mexican visitors were still making opportunities and drew level in the 65th minute.

Antuna collected the ball in a dangerous and Miami goalkeeper Drake Callender was unable to deal with his drilled strike.

Messi showed flashes of quality, skill and poise as play swung from end to end with both sides seeking a winner.

Ignacio Rivero was denied Callender and there were a few hairy moments as this helter-skelter clash continued, with Messi threaded through by Busquets only to see a shot blocked.

Martinez looked to have won it but Messi had strayed well offside before passing it and at the other end Christian Tabo was brilliantly stopped by Callender.

Play was set to end in a penalty shoot-out but Messi had other ideas.

Fouled by Carlos Salcedo, it set up the chance for an unforgettable finish and the debutant delivered a thrilling final blow.

Novak Djokovic reached yet another milestone as he continued his quest for an eighth Wimbledon title.

Victory for the Serbian over Australia’s Jordan Thompson in the second round meant he became only the third player in history, along with Roger Federer and Serena Williams, to clock up 350 match wins at grand slams.

The 23-time major champion, bidding to equal Federer’s record of eight titles in SW19, was never at full throttle against world number 70 Thompson.

He broke serve just twice but still registered a relatively routine 6-3 7-6 (4) 7-5 victory, extending his record Centre Court winning streak to 41 matches – his last defeat coming to Andy Murray in the 2013 final.

Djokovic, also chasing the calendar grand slam and bidding to become Wimbledon’s oldest men’s singles champion at 36, said: “Centre Court has been the most special court for our tennis history. I truly try to marvel and enjoy every moment I spend on the court.

“It’s a huge privilege at this stage of my career when I’m trying to push the young guns. We have a very special, romantic relationship, me and this court.”

Djokovic will face either Tomas Martin Etcheverry or former grand slam winner Stan Wawrinka in round three.

Federer, who retired last year and visited Wimbledon on Tuesday, has no doubt his mark is about to be equalled by Djokovic.

He told CNN: “I think he’s the big, big favourite. Honestly, I think it’s great for him. I had my moments.

“For me, having won my eighth or my fifth in a row or whatever it may be, that was my moment.

“So if somebody equals that or passes that, this is their thing, their moment.”

Ninth seed Taylor Fritz finally won his first-round match, two days after it started.

Bad light, and then Tuesday’s rain, meant the American and Germany’s Yannick Hanfmann resumed on Wednesday at 3-2 in the fifth set, and Fritz took it 6-4 2-6 4-6 7-5 6-3.

Former world number three Dominic Thiem was a set up on Greek fifth seed Stefanos Tsitsipas when the rain forced them off at lunchtime on Tuesday.

But in a late evening thriller on Court Two, Tsitsipas won a deciding match tie-break at 6-6 in the fifth set to set up a second-round meeting with Andy Murray.

American Frances Tiafoe, seeded 10, was a straight-sets winner over Wu Yibing of China.

But while they are through to round two and Djokovic is already safely in round three, spare a thought for Alexander Zverev, the 19th seed who is still yet to play his first-round match against Gijs Brouwer.

On this day in 2010 Serena Williams won her fourth Wimbledon title with a 6-3 6-2 win against Vera Zvonareva.

It took just over an hour for the world number one to scoop her 13th grand slam title after sealing victory against the Russian 21st seed.

Zvonareva was appearing in her first grand slam final but had no answer for Williams, who took the first set in 36 minutes.

With Zvonareva 4-1 down in the second, the American showed her ruthless streak to see out victory, taking her past Billie Jean King to sixth in the all-time list of female grand slam singles champions.

“Hey Billie, I got you, it’s number 13 for me,” Williams said after her win.

“It means a lot because it is 13 and that’s kind of cool because I was able to beat Billie. To have four Wimbledon titles is amazing.

“It’s funny, I didn’t think I was playing that well, especially in practice.

“Just wasn’t hitting the ball that cleanly, but when I got on the court, it was good.

“I served really well and to win the tournament without losing a set is pretty cool.”

Now 41, Williams has won a mammoth 23 grand slams, more than any other player in the Open era, and is one behind Margaret Court.

Her last Wimbledon singles title came in 2016, beating Angelique Kerber 7-5 6-3.

Elena Rybakina moved one win away from completing the 'Sunshine Double' and did so on the back of a serving feat last achieved by Serena Williams almost seven years ago.

Reigning Wimbledon champion Rybakina battled past Jessica Pegula in the semi-finals of the Miami Open, scoring a 7-6 (7-3) 6-4 win to book a clash with Petra Kvitova or Sorana Cirstea in the title match.

In doing so, Rybakina set up the chance of sealing an Indian Wells and Miami back-to-back double, a feat that only four women have pulled off before: Steffi Graf (1994, 1996), Kim Clijsters (2005), Victoria Azarenka (2016) and Iga Swiatek (2022).

She also becomes just the sixth woman to appear in the finals of the Australian Open, Indian Wells and Miami in the same year after Monica Seles (1991), Graf (1994), Lindsay Davenport (2000), Martina Hingis (2000) and Maria Sharapova (2012).

The Williams accomplishment that Rybakina has matched stands as testament to the Kazakhstani player's serving prowess.

She has served at least 10 aces in each of her five matches in Miami, and Williams at Wimbledon in 2016 was the last player from the WTA Tour to serve 10-plus aces in five matches in a single tournament.

Rybakina lost to Aryna Sabalenka in the Australian Open final in January but has put that behind her and enjoyed a stellar March. She beat Swiatek in the Indian Wells semi-finals before toppling Sabalenka in the final, and now another chance of a trophy awaits.

Discussing the challenge of completing the hard-court US double, Rybakina said: "It's really difficult, and because of different conditions in these two weeks by the matches you could see that it's much more difficult for me here than even in Indian Wells.

"It's just the finals, still close but the same time far. The Sunshine Double, I try my best, and hopefully I can make it. I didn't expect to be in the final. I knew that it was going to be very tough from the beginning, from the first match. And it was, actually. First two matches was really tough."

She came through dicey three-setters against Anna Kalinskaya and Paula Badosa before kicking on, winning in straight sets against Elise Mertens, Martina Trevisan and Pegula.

"Actually, the whole two weeks were really tough," Rybakina said after seeing off Pegula late on Thursday. "I'm happy to be in another final."

With her runs in Indian Wells and Miami, the Russian-born 23-year-old has already won 13 main-draw matches at WTA 1000 level in 2023, matching her personal best for an entire season, achieved last year.

Novak Djokovic has brought up his 378th week as world number one.

That sees the 35-year-old, 22-time grand slam champion overtake Steffi Graff as the outright record holder for the amount of weeks spent at the top of the world.

Djokovic won his first major in 2008, and has not looked back.

To mark his achievement, Stats Perform has used Opta data to run through the key numbers from Djokovic's stellar career.

ATP Tour titan

Serena Williams feels "more at peace" with her decision to step away from tennis but remains "torn" as a comeback crosses her mind.

The 23-time grand slam winner appeared to call quits on her career at last year's US Open after defeat at the third round stage to Ajla Tomljanovic, repeatedly referencing "evolving" away from tennis.

In October, Williams declared she had not retired and labelled the chances of a return as "very high".

With the 41-year-old still confident she can compete at the highest level, Williams struggles with the repeated questions in her head of choosing between her sporting career and enjoyment of motherhood.

"I for sure feel more at peace now," Williams told E! "It's interesting. I think I feel torn because I'm still able to play at a very, very, very high level.

"With that being said, I always wanted to leave the game playing at a very high level. I also wanted to walk away when I'm healthy and have a quality of life.

"But I'm inch by inch leaning away, inch by inch embracing it. I was playing earlier when I first retired because it was hard to do it cold turkey.

"But lately, I haven't played so much. And I miss it. I'm like, 'Oh my goodness. I have got to get out there'. But it's hard for me to get out there.

"I did play the other day, and it's just like, 'There's no way I shouldn't be playing professional tennis'. Like, there's literally no excuse.

"But I mean, I guess there is an excuse, right? It's hard because when I'm playing I'm like, 'Oh my gosh, I'm pretty good at this. I can continue to do this,' which not a lot of people can say."

Balance in life remains the key aspect Williams is trying to achieve, whether she returns to her beloved sport for one last dance or not.

"I've been playing tennis for literally my entire life," she said. "My entire being and knowing is just what I've done.

"So now, I'm inch by inch finding my way. Obviously, I love other businesses that I've done. But just inch by inch leaning into that and leaning into my family and leaning into just having fun.

"I think it's so important to do all those and still create that balance."

Novak Djokovic will play his 33rd grand slam final on Sunday, extending his men's Open Era record and edging closer to Chris Evert's leading mark across all singles players.

Djokovic beat Tommy Paul at the Australian Open on Friday to advance to a 10th Melbourne final, having won each of the prior nine.

The Serbian has also played nine title matches at the US Open, eight at Wimbledon and six at the French Open.

Even before this latest semi-final success, his tally of 32 major men's singles finals was unmatched in the Open Era.

But the 33rd saw Djokovic match Serena Williams in second place among both male and female players, with only Evert out ahead now on 34.

Djokovic will no doubt back himself to reach and perhaps pass that record before the year is out, with Roger Federer having retired and Rafael Nadal injured again – those two great rivals no longer keeping pace with the 21-time slam champion. A 22nd success on Sunday would equal Nadal's record.

With victory over Paul, Djokovic joined Federer and Nadal as the only male players in the Open Era to reach 10 or more finals at one major.

Federer went to 12 Wimbledon finals, while Nadal has played the title match at Roland Garros on 14 occasions.

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.

Serena Williams may return to the court "one more time," former world number two Tommy Haas believes.

The 23-time grand slam singles champion Williams declared her intention to "evolve" away from tennis prior to the US Open in September, with many thinking her third-round defeat to Ajla Tomljanovic signalled the end of her illustrious career.

Although, the 41-year-old hinted she may return in a recent interview with Jimmy Fallon, suggesting she may follow the example of another American sporting great.

"Tom Brady started an amazing trend," she said when asked if her competitive career may resume. "That's what I want to say."

Speaking to Eurosport Germany's tennis podcast Das Gelbe vom Ball, Haas said: "Serena had an incredible, long and strong career. 

"But I have the feeling that she is going to come back and say, 'I'm going to play one more time.' 

"She came so close to playing really well again and going far, so I think deep down it really annoys her.

"She might really be thinking about whether she wants to try again. I may be wrong because I'm not that close [to her].

"It will mostly depend on how it looks mentally, how she feels physically and whether she has the desire to torture herself like that again after achieving so much."
