Last week's Indian Wells Open champion Elena Rybakina has extended her winning streak to 10 matches after defeating Paula Badosa 3-6 7-5 6-3 in Saturday's Miami Open third round.

Kazakhstan's Rybakina, who is also the reigning Wimbledon Champion and Australian Open finalist, got the better of Badosa for the second time during her current run, also eliminating her from Indian Wells. 

The 23-year-old has to be considered one of the favourites to go all the way, having knocked off world number one Iga Swiatek and world number two Aryna Sabalenka to lift the trophy in California.

Rybakina will meet Belgium's Elise Mertens in the fourth round after she beat Croatia's Petra Martic 6-4 6-3.

Meanwhile, the biggest upset of the day was delivered by Russia's Anastasia Potapova, bouncing sixth seed Coco Gauff 6-7 (8-10) 7-5 6-2.

Potapova, who has never won a tournament above the WTA 250 level, will face China's Zheng Qinwen for a spot in the quarter-finals after her three-hour 5-7 7-6 (7-5) 6-3 triumph over Liudmila Samsonova.

Latvia's Jelena Ostapenko, the 24th seed, eliminated Brazilian 13th seed Beatriz Haddad Maia 6-2 4-6 6-3, while 20th seed Magda Linette of Poland knocked out Belarusian 14th seed Victoria Azarenka 7-6 (7-3) 2-6 6-4.

Unseeded American Clare Liu went down 4-6 7-5 6-4 against Italy's Martina Trevisan, but third seed Jessica Pegula will continue to fly the flag for the United States after advancing 6-1 7-6 (7-0) in her all-American showdown with Danielle Collins.

Hubert Hurkacz prevailed 6-7 (10-12) 7-6 (9-7) 7-6 (8-6) in a thrilling three-and-a-half hour battle against Thanasi Kokkinakis during Saturday's second round of the Miami Open.

It was Hurkacz's first match of the tournament after the eighth seed received a bye through the first round, and he came up against a match-fit Kokkinakis after the Australian went three sets in his opening victory.

The world number nine had to save five Kokkinakis match points before sealing the win with his first chance, three hours and 34 minutes after the contest began.

Kokkinakis was not the only Australian on the day to go down in a gruelling three-setter as 15th seed Alex De Minaur fell 6-7 (5-7) 7-6 (7-3) 7-6 (10-8) to Quentin Halys in three hours and 20 minutes.

It was far smoother sailing for fourth seed Daniil Medvedev in his 6-1 6-2 triumph over Roberto Carballes Baena, giving the Russian his first win since his 19-match unbeaten streak was ended at the hands of Carlos Alcaraz in the Indian Wells Open final.

The biggest upset of the day came from France's Gregoire Barrere as he eliminated 11th seed Cameron Norrie 6-3 6-2, before Adrian Mannarino ensured a great day for the French contingent with a 6-4 3-6 6-1 result against Ben Shelton in the late window.

Fifth seed Felix Auger-Aliassime needed a pair of tiebreakers to dispatch Brazil's Thiago Monteiro 7-6 (7-5) 7-6 (10-8), while big-serving 19th seed Matteo Berrettini came out on the wrong side of some tiebreakers in his 7-6 (10-8) 7-6 (7-5) loss to Mackenzie McDonald.

The skid from 18th seed Lorenzo Musetti continued as the 21-year-old went down 6-4 6-4 to Jiri Lehecka, giving the Italian seven losses from his past eight matches.

Karen Khachanov fought off the challenge of recent Chile Open finalist Tomas Martin Etcheverry 6-1 3-6 6-3, and second seed Stefanos Tsisipas received a walkover as Richard Gasquet withdrew.

World number one Carlos Alcaraz wasted no time in advancing to the Miami Open third round with a straight-sets win over Facundo Bagnis in just 64 minutes, while 13th seed Alexander Zverev suffered an early exit on Friday.

Reigning US Open champion Alcaraz eased past Bagnis 6-0 6-2, firing 12 winners and three aces for the match, committing only 11 unforced errors.

The Spaniard won the first set in 24 minutes, marking the first time he has won an opening frame 6-0 at an ATP Masters 100 event. It was also the first bagel he has dished out since beating Bagnis in Umag last year.

"I knew that I needed to be focused for my first match," Alcaraz said after his win, having triumphed in Indian Wells last week. "To start a new tournament is never easy, different conditions.

"I have to be ready to get used to these new conditions, but I was really focused on the match from the beginning, and I'm happy with the way that I played. I try to improve every day."

Alcaraz will face Dusan Lajovic after he beat 30th seed Maxime Cressy 6-4 7-6 (7-2), having knocked off Andy Murray in the first round.

Zverev was the highest seed to bow out on Friday, going down 6-0 6-4 to Japan's Taro Daniel, who beat world number four Casper Ruud last month in Acapulco.

Daniel triumphed in 73 minutes against the German, hitting 17 winners and committing only two unforced errors for the match, while Zverev gave up 18.

The Japanese wild card will meet Emil Ruusuvuori in the third round after the Finn beat 22nd seed Roberto Bautista Agut 6-4 7-6 (7-5) to open up that section of the draw.

Third seed Ruud also had few problems getting past Ilya Ivashka 6-2 6-3 to set up a clash with Botic van de Zandschulp after his three-set win over Alexei Popyrin.

Sixth seed Andrey Rublev overcame J.J. Wolf 7-6 (7-3) 6-4, having been broken in the opening game of what was a tight contest.

Jannik Sinner beat Laslo Djere 6-4 6-2, marking his 16th win out of 20 appearances at the Sunshine Double (Indian Wells and Miami), with only three other players – Novak Djokovic, Alcaraz and Hubert Hurkacz – having as many wins within their first 20 matches.

Ninth seed Taylor Fritz defeated fellow American Emilio Nava 6-4 6-1, and will face Denis Shapovalov in round three after he beat Guido Pella 6-3 3-6 6-3.

American 16th seed Tommy Paul came from a set down to beat Marc-Andrea Huesler 5-7 6-3 6-4, while seventh seed Holger Rune beat Martin Fucsovics 6-3 7-5.

Top 10 seeds Ons Jabeur, Caroline Garcia and Maria Sakkari were all eliminated in a day of upsets in the Miami Open second round on Friday.

Qualifier Varvara Gracheva earned her first career top-five win by beating 2022 Wimbledon and US Open finalist Jabeur 6-2 6-2 in only 67 minutes.

Fifth seed Caroline Garcia also crashed out, losing 6-2 6-3 to 74th-ranked Sorana Cirstea, having also recently beaten the Frenchwoman at Indian Wells.

Bianca Andreescu came from a set down to beat seventh seed Maria Sakkari 5-7 6-3 6-4 in a match that lasted over three hours.

Andreescu displayed some of the form that saw her lift the 2019 US Open title, fighting back from a set down and proving composed in the big moments.

The Canadian, who is ranked 31st, will take on 2020 Australian Open champion Sofia Kenin in the third round.

Second seed Aryna Sabalenka had few problems against Shelby Rogers, winning 6-4 6-3 in one hour and 17 minutes. Sabalenka will next face 31st seed Marie Bouzkova.

The 2023 Australian Open champion has won 65 main draw matches in WTA-1000 events, which equals Marion Bartoli and Ashleigh Barty at the 30th place since 2009 for the most wins at this level.

Indian Wells winner Elena Rybakina beat Anna Kalinskaya 7-5 4-6 6-3, and Petra Kvitova eased past compatriot Linda Noskova 6-3 6-0.

Ninth seed Belinda Bencic dropped just two games as she cruised past Leylah Fernandez 6-1 6-1, and will face Ekaterina Alexandrova next as the 18th seed needed three to get past Taylor Townsend.

Veronika Kudermetova was eliminated by Marketa Vondrousova 6-4 6-2, who goes up against Karolina Pliskova in round three after she eased past Wang Xinyu in straight sets.

Coco Gauff loves the inner "dog" in Jimmy Butler's basketball game and hopes the Miami Heat star saw plenty to admire about her own tenacity as she made a positive start at the Miami Open.

Winning 6-4 6-3 against Canadian Rebecca Marino got Gauff off the mark at this fortnight's WTA 1000 tournament, with the 19-year-old American very much at home in Florida.

Butler was watching at courtside, and the 33-year-old was so close Gauff could hardly ignore his presence.

"I mean, he was right next to my towels. I had no choice but to see him," Gauff said.

Gauff is a fan of the Heat, so to be watched by six-time NBA All-Star Butler was flattering for the teenager.

She is a high achiever herself, reaching the French Open final last year and setting up camp in the WTA top 10 rankings, so there was mutual respect, and the pair met up after Thursday's match.

"It was really cool because I love watching the Heat, they're my team. He has just that mentality, that dog in him, something that I really admire a lot," Gauff said. "I always do that when I'm on the court, but I was, like, I hope he sees that in me."

Gauff also spoke about having met players from the Buffalo Bills, the NFL franchise owned by world number three Jessica Pegula's parents.

"They might have been here for Jess, but I'm glad they stayed to watch my match," Gauff said.

Pegula beat Katherine Sebov in the match directly after Gauff's clash on the Stadium court.

Gauff said it was a "privilege" to be watched by fellow sports stars.

"I think it means more than maybe an actor or singer watching me, because it's like, as an athlete, finding the time to appreciate other sports is really hard," she said. "For them to want to do that, especially for a sport like tennis, which generally most of them don't understand, is really cool."

Gauff next faces Anastasia Potapova, the Russian player who beat Ukrainian Marta Kostyuk at the last-64 stage.

That match was notable largely for Kostyuk's refusal to shake hands afterwards with Potapova, a player who earlier this month was warned by the WTA for wearing a Spartak Moscow jersey at Indian Wells.

Russian and Belarusian players are competing under a neutral flag on the WTA Tour this season, amid the continuing invasion of Ukraine.

Jessica Pegula and Coco Gauff headlined a great day for the Americans at the Miami Open as they both advanced into the third round on Thursday.

Pegula, who is the second-highest seed remaining in the field after Iga Swiatek's withdrawal, had no issue dispatching Canada's Katherine Sebov 6-3 6-1 in just 66 minutes.

Gauff, the six seed, followed suit as she raced to a 6-4 6-3 win over Canadian Rebecca Marino in just 73 minutes.

Florida's own Danielle Collins thrilled her hometown crowd with a 7-6 (7-3) 6-2 triumph against Bulgaria's Viktoriya Tomova, and rising 22-year-old talent Clare Liu made it a perfect 4-0 sweep for the USA representatives by defeating Julia Grabher 6-4 6-3.

Last week's Indian Wells Open champion Elena Rybakina was made to work in her 7-5 4-6 6-3 win over Anna Kalinskaya, while an even more gruelling effort was required in Paula Badosa's two-hour-and-52-minute 7-6 (7-2) 4-6 6-2 result against Laura Siegemund.

The top seed to fall on Thursday was eighth seed Daria Kasatkina, as she won the first set before going down 4-6 6-2 6-2 against Elise Mertens.

Liudmila Samsonova, the 12th seed, made light work of Viktorija Golubic in a 6-1 6-1 drubbing, and 22nd seed Jelena Ostapenko prevailed 6-3 6-4 against Mirjam Bjorklund.

Ostapenko will next play 13th seed Beatriz Haddad Maia after she won a strange back-and-forth contest 7-6 (7-4) 0-6 6-0 over Tereza Martincova.

Richard Gasquet will get a showcase match against second-seed Stefanos Tsitsipas in the second round of the Miami Open after prevailing 6-4 3-6 6-1 against Christopher O'Connell on Thursday.

The biggest names in the field learned their opponents after the 32 seeded entrant received byes into the second round of the Masters 1000 event, and Tsitsipas will be desperate to avoid a third consecutive loss after quick exits at the Rotterdam Open and Indian Wells Open in recent weeks.

Fourth seed Daniil Medvedev is waiting for Roberto Carbellas Baena after he blew away Bernabe Zapata Miralles 6-0 3-0 (retired) in an all-Spanish showdown, while fifth seed Felix Auger-Aliassime will meet Brazil's Thiago Monteiro in the second round after his 6-4 7-6 (8-6) triumph over Australia's Jason Kubler.

After O'Connell and Kubler both fell, Thanasi Kokkinakis flew the flag for Australia with a 4-6 6-3 7-6 (9-7) comeback against Belgian wildcard Zizou Bergs, and his reward will be a battle against Polish eighth seed Hubert Hurkacz.

France's Gregoire Barrere earned a big matchup against 11th seed Cameron Norrie after eliminating Roman Safiullin 6-4 3-6 6-3, and Safiullin's Russian compatriot Pavel Kotov will join him on an early flight home after going down 6-2 6-2 against recent Chile Open finalist Tomas Martin Etcheverry.

Andy Murray believes Carlos Alcaraz can be a dominant figure in tennis "for as long as he wants" but cautioned against expecting him to challenge the grand slam records of the Big Three.

Roger Federer's haul of 20 slam titles has been overtaken by Rafael Nadal and Novak Djokovic, who both have 22 majors, but those three are streets ahead of every other men's singles player in history.

Next on the list is Pete Sampras with 14 slams, which was itself a total that many once fancied would not be beaten for decades.

Murray was for a time part of a Big Four, until he got left behind by the relentless winning of his three great rivals. Federer has retired, but Djokovic and Nadal may yet have more slam titles in them.

At the age of 19, Alcaraz is already off the mark, winning the US Open last year, and he has jumped back to world number one after winning the Indian Wells Open on Sunday.

Djokovic and Nadal will be big threats to Alcaraz's hopes of triumphing at the French Open, but the young Spaniard is no longer simply the coming player on the ATP. He has arrived, and Murray is convinced Alcaraz is the real deal and poised to stay at the top of the sport for years to come.

"He has an excellent game, an all-around game that I think will translate well onto all surfaces," Murray said.

"He's not the biggest guy, but he can serve big. He's an unbelievable mover, great athlete. Has a lot of variety in his game. Takes the ball on a lot. That's something that you hope that he keeps.

"I know from experience that it's a bit easier playing that way when you're sort of 18, 19, and there's not any scar tissue there. I hope that he maintains that style of play because it's exciting to watch."

The prediction that Alcaraz can be an all-court player, and therefore succeed on grass as well as the hard and clay courts where he has already found success, bodes well for his prospects of stacking up slams.

Murray might have faced Alcaraz in round three at the Miami Open this fortnight, but the veteran Briton, a three-time slam winner and former number one, lost his opener on Wednesday to Serbian Dusan Lajovic.

There have only been two matches on tour between Alcaraz and Murray to date, both coming in the 2021 season when they won one each.

Alcaraz is the defending champion in Miami, and a clear favourite after crushing Daniil Medvedev in the Indian Wells title match. He brings a 14-1 record for the year into the tournament.

"He's obviously so far in his young career doing better than most of the guys that have come in the last eight to 10 years," Murray said.

"I know a lot of people are expecting everyone to win 20-plus grand slams now, like that's sort of normal. I wouldn't predict that for anyone.

"I would imagine he would be right at the top of the game for, well, as long as he wants to play."

Two-time Miami Open champion Andy Murray has been eliminated in the first round of this year's event after a shock 6-4 7-5 loss to world number 76 Dusan Lajovic on Wednesday.

Murray, ranked 53rd in the world, could not find his usual return with Lajovic winning 72 per cent of second-serve points, prevailing in one hour and 38 minutes.

The Serbian claimed only his fourth win out of 16 matches on hard courts since the start of last year, holding his nerve after failing to serve out the match at 5-4 in the second set, converting his third match point in the 12th game.

Lajovic hit 21-14 winners, with Murray committing more unforced errors (15-13). The Serbian converted all three break points he generated.

Former world number six Gael Monfils was forced to retire due to a right wrist injury in his clash with French compatriot Ugo Humbert at 3-3.

Monfils, 36, was playing at only his third event since returning to the ATP Tour following seven months out due to injury.

Argentina's Facundo Bagnis defeated Brazilian qualifier Felipe Meligeni Alves 6-3 1-6 6-4, with his reward a second-round clash with last week's Indian Wells Open winner and top seed Carlos Alcaraz.

World number 50 J.J. Wolf beat world number 48 Alexander Bublik 7-5 6-3 in 79 minutes, earning a second-round clash with sixth seed Andrey Rublev.

World number 74 Martin Fucsovics sent down nine aces as he beat Argentina's Pedro Cachin 6-4 7-6 (7-2) in 107 minutes. Fucsovics will next face seventh seed Holger Rune.

Ilya Ivashka beat Daniel Altmaier 6-2 6-1 to book a second-round clash with third seed Casper Ruud, while Fabio Fognini bowed out, losing 6-4 5-7 6-4 to Jan-Lennard Struff. USA's Brandon Nakashima powered to a 7-6 (7-3) 6-3 victory over Germany's Oscar Otte.

Emma Raducanu was bundled out of the Miami Open in the first round by form US Open champion Bianca Andreescu in a three-set match that lasted two hours and 35 minutes on Wednesday.

The Briton, who won the US Open in 2021, went down 6-3 3-6 6-2 in a genuine tug-of-war against the 31st-ranked Canadian.

Andreescu sent down seven aces for the match, including four in the first set along with 12 winners as she claimed an early lead.

Raducanu responded with greater aggression, securing the crucial break in the eighth game, before serving out to level the contest.

But Andreescu showed composure and quality in the big points in the final set, winning the final four games to round out the victory, sealing a second-round clash with seventh seed Maria Sakkari.

Andreescu finished with 32 winners compared to Raducanu's 20, while the Briton committed 40 unforced errors.

World number 42 Shelby Rogers edged out USA compatriot Sloane Stephens in just under two hours, winning 6-4 3-6 6-2. Rogers will take on second seed Aryna Sabalenka, who is arguably the tournament favourite after top seed Iga Swiatek's withdrawal, in the next round.

Rogers was one of five Americans to progress, including 2020 Australian Open champion Sofia Kenin who defeated Australia's Storm Hunter 6-0 7-6 (7-5).

World number 35 Amanda Anisimova retired down 7-6 (7-5) 5-2 to countrywoman Madison Brengle.

Leylah Fernandez, the player whom Raducanu beat in the 2021 US Open final, advanced into the second round with a 6-4 6-3 victory over Lesia Tsurenko in 88 minutes.

Iga Swiatek has withdrawn from the Miami Open with a rib injury.

The world number was due to defend her title, having won the tournament last year without dropping a set.

However, she will be unable to feature in Florida due to an ongoing rib issue that has plagued her since the Qatar Open in February.

Swiatek reached the semi-finals of the Indian Wells Open last week, losing to eventual champion Elena Rybakina, and hinted at concerns over her condition.

The Pole confirmed on Wednesday that after consulting with her medical team, she will not play her second-round match against Claire Liu on Thursday and will also miss the Billie Jean King Cup, which takes place in April.

"You know that in and after Doha I was struggling with a strong infection," Swiatek said. 

"I was allowed to play, but a strong episode of tough cough led to a rib injury. We were trying to handle it and continue to play as long as it was safe for me. We were analysing the data in the last [few] days and my doctor prepared my diagnosis.

"Unfortunately, I'm still feeling a lot of discomfort and pain and I can't compete.

"I will keep you updated about where I play next, because it depends on my process of recovering and the recommendation of my medical team. 

"I have the best team behind me, we only need some time to deal with the injury. It's a truly difficult call to not play in Miami and the Billie Jean King Cup, but health is the most important [thing].

"I'm grateful this is the first health issue in a long time and I was able to compete in perfect shape for so long, but that's sports, it happens sometimes, without our control. 

"Time to accept it and get well as soon as possible."

Swiatek will be replaced in the women's draw by lucky loser Julia Grabher.

The 21-year-old will now hope to be fully fit in time for the clay-court season, including the French Open, where she is the reigning champion.

Novak Djokovic does not regret his decision not to be vaccinated against COVID-19, despite losing the world number one ranking.

Djokovic has spent a record 380 weeks at the top of the rankings but was unable to compete in the first two ATP 1000 events of the season – the Indian Wells Open and the Miami Open – after his request for special permission to travel to the United States was declined.

The US currently bars unvaccinated travellers from entering the country, although that policy is set to be scrapped in May. 

With the 22-time grand slam champion unable to feature, Carlos Alcaraz returned to the top of the rankings with victory at Indian Wells.

"I have no regrets," Djokovic told CNN.

"It's a pity that I wasn't able to play in Indian Wells [and] Miami. I love those tournaments. I had plenty of success there. But at the same time, it is the conscious decision I made and I knew that there was always a possibility that I wouldn't go. 

"It is the current state or current situation that I hope will change later this year for the US Open. That is the most important tournament for me on American soil.

"I've learned through life that regrets only hold you back and basically make you live in the past and I don't want to do that. 

"I also don't want to live too much in the future. I want to be as much as in the present moment, but of course, think about the future and create a better future."

Alcaraz, who won the US Open in 2022, romped to last week's title at Indian Wells with a comprehensive 6-3 6-2 victory against Daniil Medvedev in the final.

"I congratulate Alcaraz," Djokovic said. "He absolutely deserves to come back to number one."

Djokovic's attention will now turn to the clay season in Europe as he gears up to try and win a third French Open title.

"I'm as enthusiastic as ever, as motivated as ever for the sport, my family, my foundation, all the projects and everything I'm doing off the court," he added.

"The dignity, and integrity, and staying true to myself, and my beliefs and my rights are above everything."

Aryna Sabalenka received "hate" in the dressing room after Russia's invasion of Ukraine.

Sabalenka finished as runner-up at Indian Wells last week, losing to Elena Rybakina, who she defeated in the Australian Open final in January.

Born in Belarus, an ally of Russia, the 24-year-old revealed ahead of her Miami Open campaign that "weird conversations" had come from members of other players' teams, rather than her fellow pros.

"It was really tough for me because I've never faced that much hate in the locker room," she said. "There are a lot of haters on Instagram when you're losing matches, but in the locker room I've never faced that.

"I had some, not like fights, but I had some weird conversations with, not the girls, but with members of their team. It was tough. It was a tough period. But now it's getting better.

"It was really tough to understand that there's so many people who hate me for no reason. I did nothing."

Players from Russia and Belarus have been classed as neutral since the invasion, and were banned from last year's Wimbledon.

Ukraine's Lesia Tsurenko pulled out of her match against Sabalenka at Indian Wells after suffering a panic attack following a conversation she had with WTA chief executive Steve Simon about tennis's response to the invasion.

World number one Iga Swiatek had called for greater support for Ukrainian players as a result of the conflict but another Belarusian, Victoria Azarenka, disagreed.

"There are certain players that have different feelings and behaviours. Overall, I don't necessarily share the same opinion as Iga does," Azarenka said.

"I'd encourage her to look at the things that have been done before she makes comments. As a player council member I'm happy to provide the facts. That would be a more appropriate way to have that conversation."

Camila Giorgi progressed into the Miami Open second round despite blowing a 5-0 third-set lead as she edged past veteran Kaia Kanepi in the equal-longest main draw match of the year on Tuesday.

The Italian world number 44, who won February's Merida Open, outlasted the Estonian 7-6 (7-4) 6-7 (4-7) 7-6 (7-4) in three hours and 32 minutes.

The length was equal to the Erika Andreeva-Harriet Dart first-round match at the ATX Open last month for the longest this WTA season.

But Giorgi could have had an earlier finish, leading 5-0 in the decider before Kanepi hit back by winning the next five games, only for the Italian to rally in the tie-break, converting her fourth match point.

Giorgi, who blew match points at 5-3 and 5-4, will take on three-time Miami Open winner and 2023 Australian Open semi-finalist Victoria Azarenka in the second round.

Russian 34-year-old Evgeniya Rodina produced the upset of the day's play, beating 37th-ranked Bernarda Pera 6-3 6-4 in 73 minutes and will take on 20th seed Magda Linette in the second round.

Rodina is currently ranked 369th in the world having returned to the WTA Tour midway through last season after a two-year absence, having reached a career-high 67th in May 2019.

World number 39 Elise Mertens eased into the second round with a 6-1 6-4 win over USA's Alycia Parks, setting up a second-round clash with eighth seed Daria Kasatkina.

World number 43 Yulia Putintseva bowed out prematurely, going down 7-6 (7-4) 6-2 to Canada's Rebecca Marino, who advanced to face sixth seed Coco Gauff.

Teenager Linda Fruhvirtova, ranked 50th in the world, also suffered a shock loss, beaten 6-2 4-6 6-4 by 172nd-ranked Canadian qualifier Katherine Sebov, while Laura Siegemund won 6-3 6-4 over 52nd-ranked Mayar Sherif

Katerina Siniakova withdrew due to injury despite winning the first set against USA's Claire Liu, with scores at 6-3 3-3. Liu's prize is a second-round meeting with top seed and reigning champion Iga Swiatek.

Martina Navratilova has announced she is cancer-free, with Billie Jean King welcoming the "wonderful news".

Doctors believe the 66-year-old tennis great has beaten cancer for a second time, after previously overcoming breast cancer in 2010.

The Czech-American announced in January she had been diagnosed with throat and breast cancer, sparking an outpouring of well-wishes.

She is one of the most decorated players of all time, having won 18 grand slam singles titles between 1978 and 1990, plus a staggering 41 doubles slams.

Speaking to Piers Morgan on TalkTV, Navratilova said: "As far as they know, I'm cancer-free."

According to The Sun, Navratilova will have further preventative radiation treatment on her breast.

"Then I should be good to go," she said.

King, her friend and former tennis rival, was thrilled to learn Navratilova's health has taken a turn for the better.

She wrote on Twitter: "Such wonderful news from my dear friend, ⁦@Martina⁩. We are so happy for you!"

Speaking to Stats Perform prior to Navratilova's announcement, former ATP world number two Tommy Haas spoke of his admiration for the legendary left-hander, and wished for a full recovery.

"What she has done in women's tennis and her success, the way she also kind of showcased her athleticism, her focus, her dedication to the sport, the records that she's broken, the longevity of it too," Haas said, listing reasons to be an admirer.

He described her as "an icon on the tour", and hoped she would survive this year's worrying cancer scare.

"Obviously, when you read the news about anyone in the tennis world that has had some kind of impact, or a great career, it's always sad, and you send them a text message, and you wish them the best and a speedy recovery," said Haas, the Indian Wells Open tournament director.

"You hope that they found these situations early, just like with Chris Evert [who recovered from ovarian cancer], and that they get through this and that they have the loved ones and friends around them and support them and get back to what they enjoy doing in life.

"I think we all know, and realise that without health, you have nothing. It's nice to be a part of certain things that you're passionate about. And it's important, and it's great, but being healthy and doing the things that you want to do ultimately, is really what it comes down to."
