Indian Wells

Former world number one Halep was due to face Australia's Daria Saville in the round of 64 on Thursday but felt unable to contest the match.

Halep said she sustained a thigh injury during her Indian Wells semi-final defeat to Iga Swiatek the previous week and it caused her discomfort again while training on Wednesday.

The 30-year-old two-time major winner expects to sit out the Charleston Open and will miss the start of the Billie Jean King Cup.

In a tweet posted on her official Twitter account, Halep wrote: "While I was practising in Miami yesterday I felt a sharp pain in my left leg.

"I had been struggling with the thigh since my semi-final in Indian Wells and hoped it would improve, but I went for an MRI last night and unfortunately it showed a tear.

"My body needs time to heal and as a result I will be out of competition for three weeks. This means I have had to make the super tough decision to pull out of Miami, Charleston and Fed Cup [Billie Jean King Cup].

"While it feels like really disappointing news to share, I am keeping the confidence from my great start to the year and am motivated to do everything to be ready for the clay-court season.

"Thanks for your continued support through the highs and lows."

Lucky loser Harmony Tan will take Halep's place in the draw.

The 18-year-old achieved stunning success at the US Open, winning the grand slam event as a qualifier without dropping a set.

Raducanu will play her first match since that famous Flushing Meadows triumph when she takes on Aliaksandra Sasnovich at the Indian Wells Open on Friday.

The youngster has been rated as favourite to win the tournament, which is seen as one of the most prestigious outside of the four majors.

There is already talk of her qualifying for the lucrative season-ending WTA Finals and triumphing at Wimbledon next year, having burst onto the scene in 2021 by reaching round four at All England Club.

But fellow Briton Henman urged fans to show caution with what they expect from Raducanu before her first match in 27 days against seasoned pro Sasnovich.

Raducanu has regularly discussed her lack of experience at tour level while she searches for a new coach to show her the ropes and Henman did not want to entertain discussions of her winning Wimbledon in 2022.

"I think that is probably getting a little ahead of ourselves," Henman said to talkSPORT. 

"She has shown her enormous potential by what she did in New York, but she is still so young and so inexperienced. 

"She has played so few events on the tour, let alone at grand slam level. I think it’s very easy to get ahead of ourselves.

"Regarding some of the young up and coming players, to really understand where they are at and their development, for me you get a very good insight once they have played every tournament twice.

"To put it into context, she has never played the clay court swing, she’s never played Roland Garros, she has never played the Australian Open.

"Once she has played all those events twice, then we will be able to assess where her game is at.

"Right now, it is as much about the process as the outcome and keep developing her game."

Henman, though, was in no doubt that Raducanu is a prodigious talent.

He added: "What is exciting is that she can improve in so many areas. 

"It is easy to focus on her tennis game, but she can get fitter, stronger, faster and gain experience playing at the highest level and continue improving her tennis game.

"If she does that then I think she will go on and win more tournaments in the future.

"It was a privilege to be on the side of the court for all her main draw matches and just see the quality of her tennis at close quarters.

"Her resilience mentally, her composure and the consistency was incredible. To win 20 straight sets to qualify and win a grand slam is unprecedented in our sport, it was a real pleasure to watch."

While Raducanu received a first-round bye, Sasnovich had an easy opener as she beat Maria Camila Osorio Serrano in straight sets.

The Belarusian has never won a WTA Tour event or reached the last eight of a major.

Thursday was to be a recovery and re-setting day for Greek Sakkari, one of the stars of the Netflix 'Break Point' series, who is through to her third semi-final of the year.

She booked a last-four spot thanks to a stunning fightback from a set and a break down to Petra Kvitova, but Sakkari's efforts this week in California have left her with bleeding toes.

It is hardly surprising, considering she has taken a long route through to the semi-finals, reeling off four consecutive three-set wins.

Sakkari has lost the first set in three of those four matches but found a way to battle back, but she will want to start strongly against a dialled-in Sabalenka.

After coming through 4-6 7-5 6-1 against Kvitova, Sakkari said in an on-court interview: "I need a pedicure because my feet are bleeding so badly."

Asked about that comment later, she said in a press conference: "It's just my nails. It's not ideal, but nothing bad, like I can properly play and run and everything, but it's not nice."

It sounds far from pleasant, yet Sakkari fights on, aware that despite not playing her top-level tennis so far this fortnight, resilience has pulled her through.

"It is strange, but at the same time, I'm just telling myself, look, you're not playing your best tennis and you're still winning and beating amazing players," Sakkari said.

"By just surviving and just finding ways, eventually I'm sure that my game is going to get better. I really want to see how it's gonna be when I will start feeling good with my game.

"But of course I don't want to say that like I was playing s*** and I won. That's not the case. That's also very bad for the opponent."

Considering Kvitova is a two-time Wimbledon champion and a 29-time singles title winner on tour, Sakkari ranked Wednesday's win as one to log alongside her finest victories.

"For me coming back against her, now that she's playing good, now that she has beaten so many good players, it's a bloody good win," Sakkari said. "The fact I found a way was one of the best comebacks of my life."

Sakkari trails 4-3 in the career head-to-head against Sabalenka despite winning their last two encounters, both at the WTA Finals in each of the past two seasons.

They have not faced each other since Sabalenka became a first-time grand slam champion in Melbourne at the start of the year.

Sakkari was runner-up at Indian Wells 12 months ago, losing to Iga Swiatek in the final, and she has designs on beating Sabalenka to earn another crack at the title match.

Asked about the Belarusian, Sakkari said: "She's an amazing player. I knew that she was gonna win a grand slam. It actually came, and I was very happy for her.

"She's very fun to be around. It's going to be very, very tough, because she's feeling the ball really well."

It took little more than an hour for Poland’s Swiatek to beat Kazakhstan’s Yulia Putintseva in straight sets 6-1 6-2.

Wozniacki, from Denmark, defeated three-time Grand Slam winner Angelique Kerber in 90 minutes 6-4 6-2, advancing to her first WTA 1000 quarter-final since 2019 after returning to the tour.

After her match, former world number one Wozniacki said she will have to play her “best tennis to compete” with Swiatek.

“I think I have obviously commentated some of her matches,” she said. “I know how she’s playing. Obviously she’s playing good tennis, playing powerfully.

“I practiced with her as well a few times after I have come back, during the US Open as well. I know how she plays, but it’s one thing knowing how she plays and also playing against her in a full match.”

Swiatek said on court that she has great respect for Wozniacki.

“I think she’s playing great even after the maternity break. She was fighting to come back.

“I have huge respect. I’m going to prepare like any other, but off the court she’s a great person.”

Ukrainian Marta Kostyuk defeated Russian Anastasia Pavlyuchenkova 6-4 6-1, while Russian Anastasia Potapova defeated Italian Jasmine Paolini 7-5 0-6 6-3.

The American 20th seed, who has never been further than the fourth round at a major, claimed a breakthrough maiden ATP Masters 1000 title with a 6-3 7-6 (7-5) victory over Nadal in two hours and six minutes.

Fritz, 24, was not sure if he would be able to take his place in Sunday's decider after tweaking his ankle in Saturday's semi-final win over Andrey Rublev which he battled in the lead-up.

The injury was far from ideal preparation coming up against the Spanish fourth seed, who was on a 20-0 run to start 2022 having won January's Australian Open for a record-breaking 21st career major.

"I can't even begin to describe how ridiculous it is that I was able to play how I could play today," Fritz said during his post-match on-court interview. "I've never ever experienced worse pain in my life before a match.

"If I knew it was going to be that bad, I wouldn’t have come out here [beforehand] because I think people saw it. I took a couple of change-of-direction steps and screamed.

"I was trying to act tough as I had cameras on me. It probably looked like I was over-exaggerating the pain with how loud I screamed when I felt it.

"We did a lot of work leading up to the match. I went through a roller-coaster of emotions before the match, from thinking there's no way I could possibly play then to doing so much work on the ankle and going out again hitting on one of the backcourts and being really happy, thinking I can play.

"Really it didn’t affect me out on the court. Unbelievable."

California native Fritz, who reached last year's Indian Wells semi-finals, admitted winning the event was a "childhood dream" and that it did not feel real.

"I'm going to have to hold back tears for every single interview I do and every on-court speech," he said. "This is going to be tough. I'm such a happy crier.

"This is one of those childhood dreams, winning this tournament especially, you never thought would come true. I keep saying 'no way this is real'."

The title is the biggest of Fritz's career to date, triumphing in his first Masters 1000 final, and becoming the first American men's champion at Indian Wells since Andre Agassi in 2001.

Fritz is also the youngest male champion at the event since Novak Djokovic in 2011 and achieved that by ending Nadal's career-best 20-match win streak, denying him a record-tying 37th ATP Masters 1000 title too.

"I've lost these matches against the big guys my whole life," Fritz said. "It's always felt like they're unbeatable. To do it on the biggest stage, there's no other way. To win a big title, I feel like you've got to beat the best."

Sport was given a jolt three years ago when Indian Wells organisers cancelled the event on the eve of action getting under way, citing one local case of COVID-19.

At that point, on March 8, 2020, there had been more than 500 confirmed cases across the United States, with 21 deaths. Soon enough, events across the globe were being postponed or scrubbed.

Coronavirus travel restrictions prevented the unvaccinated Djokovic from taking part last year, and they will keep him away again this time, despite calls from two Florida senators for the jab requirement to be lifted by President Biden to allow the Serbian into the country.

With the world number one sidelined, Daniil Medvedev and Carlos Alcaraz look likely challengers for the men's title. There have been surprise champions in recent times, with Cameron Norrie winning in 2021 and Taylor Fritz carrying off the title 12 months ago, so it would be hasty to rule out something similar.

In the women's event, there has not been a successful title defence since Martina Navratilova won in 1990 and 1991. That can partly be attributed to Serena and Venus Williams boycotting for over a decade at the peak of their powers after complaining of facing racial abuse, and in their absence no player stepped up to dominate.

Iga Swiatek triumphed in Indian Wells and Miami last season, racking up the 'Sunshine Double', and she starts as a strong favourite again, but defeat in the recent Dubai final to Barbora Krejcikova showed the 21-year-old rankings leader will not have everything her way this season.

First-round action gets under way on Wednesday, after two days of qualifying, and here Stats Perform, with Opta data, looks at what lies ahead.

After Norrie and Fritz, could there be another shock men's winner?

Djokovic has won a joint-record five Indian Wells titles, but he last featured in 2019, when he lost to Philipp Kohlschreiber in round three.

Rafael Nadal is also absent this time with a hip injury, and with Roger Federer retired this will be the second Indian Wells main draw since 2000, after 2021, to feature none of the ATP Big Three.

The Big Three was a Big Four at one point, though, and Andy Murray will be competing. It is one of the two Masters 1000 tournaments Murray has never won, along with Monte Carlo, having triumphed at the other seven. Murray has the most match wins at Indian Wells among all men competing this time, having 28 to his name, two more than John Isner who sits next on the list.

No ATP player has a better win percentage at Indian Wells than Djokovic (84.7 per cent), who has won 50 of his 59 matches, while the now-retired Federer has appeared in the most finals (nine), also winning five times, so there is no doubt the field is missing its long-time classiest acts.

Fritz last year became the first men's champion aged under 25 years old since Djokovic in 2011, and he was also the first American to take the men's title since Andre Agassi beat Pete Sampras in the 2001 final.

Medvedev has won three consecutive tournaments in the lead-up this year, tearing to titles in Rotterdam, Doha and Dubai, but the Russian has a disappointing record at Indian Wells, having yet to reach the quarter-finals in five visits.

Just four players this century, including Alcaraz last year, have reached the semi-final stage before turning 20, with Nadal, Djokovic and Murray the other three. Alcaraz is still only 19 but a shade older than Boris Becker when he was a 19-year-old champion in 1987, the youngest men's winner.

Who else might come through? It feels like a free-for-all and Felix Auger-Aliassime will be hoping for a breakthrough tournament, with the Canadian being the only member of the current ATP top 10 to have never reached a final at ATP 1000 level. It has to happen sooner rather than later, surely.

Swiatek bids to lift curse of women's champions

Ever since Navratilova's two in a row, being a back-to-back champion at Indian Wells has been beyond all singles players on the WTA side.

Indeed, the only players to reach the final the year after their title run have been Lindsay Davenport (champion 1997, runner-up 1998) and Ana Ivanovic (champion 2008, runner-up 2009).

Nine women have won twice at Indian Wells, but none have managed three or more titles. The nine are: Steffi Graf, Mary Joe Fernandez, Navratilova, Daniela Hantuchova, Serena Williams, Kim Clijsters, Victoria Azarenka, Davenport and Maria Sharapova.

A Swiatek victory would make it a club of 10, but there is a club of one when it comes to players who have captured two titles without dropping a set in either trophy run. Sharapova is the only player to pull off that feat, with her 2006 and 2013 glory runs.

Among all women, Davenport has reached the most finals (six) and won the most matches (47), with Azarenka having the most wins among active WTA players (34).

Navratilova remains the oldest champion, having won aged 34 in 1991, while Martina Hingis and Serena Williams won as 17-year-olds in 1998 and 1999.

Shocks can happen: Bianca Andreescu took the title as a wildcard in 2019, while Jenny Byrne reached the final as a qualifier in 1989, the first year the women's event was staged.

If there is to be a teenage women's finalist this time, maybe it will be Coco Gauff. The American turns 19 midway through the tournament, on March 13, and has yet to reach a WTA 1000 final, although she got to the French Open title match last year, where Swiatek inflicted a heavy defeat.

Perhaps Aryna Sabalenka can reprise her Australian Open form, having won a first major in Melbourne. But Sabalenka's record in Indian Wells is a rough one, with the Belarusian yet to go past the fourth round.

Strap in for a thrill ride. They all want to stop Swiatek, but if any player can defy history it might just be the Pole.

Muguruza, who won the WTA Finals title at the end of last season, was cruising at 6-0 3-0, but 31-year-old American Riske, despite tossing her racket in frustration, refused to give up. Incredibly, she won 12 of the next 13 games to reach the third round at the expense of the world number nine.

"After the first set, it literally could not get any worse," Riske said in her on-court interview following a 0-6 6-3 6-1 success.

"So if I could try to get two balls in the court we might get somewhere. I was just trying to hang in there. I've played Garbine many times before and it's always been a battle."

This was Riske's fifth match against Spanish star Muguruza, and despite losing the first two of those, she had since beaten the two-time grand slam winner twice, albeit most recently at the 2019 US Open.

"I felt if I could get in there a little bit, I was going to have my chances," Riske said. "I know I've beaten her before, and if I could just bring out some of my game, good things were going to happen."

It was world number 53 Riske's 10th career victory against a player ranked in the top 10.

British player Harriet Dart pulled off a shock win over Ukrainian Elina Svitolina, as the world number 122 snatched a 2-6 6-3 6-3 victory over the 12th seed.

Three of the biggest names in the draw took the long route through to the last-32 stage, with Emma Raducanu, Simona Halep and Iga Swiatek taken to a deciding set in their opening matches, having benefited from first-round byes 

Raducanu fended off Caroline Garcia 6-1 3-6 6-1, while Halep was a 6-2 4-6 6-2 winner against Ekaterina Alexandrova, the Russian who is playing under a neutral flag.

Polish third seed Swiatek put a slow start behind her to beat Ukrainian Anhelina Kalinina 5-7 6-0 6-1 and is looking to build on her recent Qatar Open triumph. She said: "I'm pretty happy I could turn my head on to fight mode and stay focused, because that was the key I guess."

Last year's Wimbledon runner-up Karolina Pliskova bowed out, the Czech seventh seed losing 2-6 7-5 6-4 to Danka Kovinic of Montenegro.

Having to take a medical timeout during his win in the semi-final against countryman Carlos Alcaraz, the 35-year-old was forced into another injury break against Fritz, before losing 6-3 7-6 (7-5).

Nadal, whose 2021 was halted mid-year due to foot injury after back pain at the start of the season, ultimately rued his inability to fully compete against Fritz.

"I had pain, honestly. I had problems breathing," he said post-match. "I don't know if it's something on the rib, I don't know yet. When I'm breathing, when I'm moving it's like a needle all the time inside. I get dizzy a little bit because it's painful.

"It's a kind of pain that limits me a lot. It's not only about pain, I don't feel very well because [it] affects my breathing."

Nadal's 20-match unbeaten streak for 2022, which saw him claim the Australian Open and Acapulco titles in the process, also came to an end on Sunday. The world number four said the streak ending before coming into the clay season provides particular sadness.

"Honestly, I wanted to make it perfect before clay. [It] has been very, very, very beautiful," Nadal said.

"Honestly, I am sad because the way I was not able to compete. It's tough to have these feelings….but in the final it's very, very ugly. But in sport it's not about talking of the past, we need to talk about today. And today is a difficult day for me. "

Nadal commended Fritz on the victory, however. The 24-year-old claimed his maiden ATP 1000 title despite carrying an ankle injury.

According to the 21-time grand slam winner, it is a sign of things to come from the American, who had to back up from a tough win over Andrey Rublev in the semi-final on Saturday.

"Victories like today help. He played well. He went through some great matches during this week I think, especially yesterday," he said.

"A lot of credit to him on the victory of yesterday. In my opinion, his victory of yesterday is much bigger than his victory of today because he had [a] much tougher opponent in from yesterday.

"He already played great matches in Australia, this year if I'm not wrong, against [Stefanos] Tsitsipas.

"It's obvious that he is improving. With this victory, it's a great start of the season for him. He will have a chance to be very close if not in the top 10 very soon."

Former world number five Anderson – a US Open and Wimbledon finalist in 2017 and 2018 respectively – confirmed the news on his official Twitter account on Friday.

The 33-year-old, now ranked at 121, slumped out in the second round of the Australian Open in January before succumbing to Jason Jung in the round of 32 at the New York Open this month.

Anderson will now miss the Mexico Open, where he is a two-time finalist, along with the Masters events at Indian Wells and Miami and seems set to face a race against time to be fit for the French Open in May.

He has confirmed the injury to his right knee was sustained during off-season training in December, with scans in Australia confirming a medial meniscus tear.

"It is beyond difficult and frustrating to have to deal with this, after the setbacks I had last year," Anderson posted on Twitter. "But I know it's the right decision for me to get back where I want to, and rest assured I will do everything in my power to get there."

The Swedish qualifier, who reached her first WTA final in four years in Merida having had her 2022 derailed by injury, triumphed 7-5 5-7 7-5 over the Ukrainian world number 40 in almost three hours.

Kostyuk, ranked 40th in the world, was not helped by 17 double faults across the match, with Peterson progressing to the second round where she will face 22nd seed Zhang Shuai.

Alize Cornet was also a surprise first-round loser, going down 6-2 7-5 to 427th-ranked Evgeniya Rodina in one hour and 42 minutes.

Rodina's prize for her shock victory is a second-round date with 2023 Australian champion and second seed Aryna Sabalenka.

Camila Giorgi, who beat Peterson for the aforementioned Merida Open crown last month, won through with a routine 6-3 6-3 victory over Arantxa Rus. Giorgi will next face third seed Jessica Pegula.

World number 41 Shelby Rogers was pushed for two hours and 22 minutes by Katie Volynets but triumphed 6-4 4-6 6-1. Rogers will take on seventh seed Maria Sakkari in the second round.

China's Wang Xin, making her Indian Wells debut, defeated former world number 12 Elise Mertens 6-3 6-1, while world number 33 Zhu Lin was downed by Lesia Tsurenko 6-4 6-3.

Aliaksandra Sasnovich won 6-3 7-6 (7-5) over veteran Kaia Kanepi, while 53rd-ranked Linda Fruhvirtova fought back after copping a bagel to win 0-6 6-2 6-3 over 52nd-ranked Mayar Sherif.

Jil Teichman set up a second-round clash with Swiss compatriot Belinda Bencic after a 6-1 6-4 victory over Ashlyn Krueger.

The 2022 Wimbledon runner-up was left "devastated" after being forced to withdraw from the Australian Open on home soil last week.

Kyrgios was ruled out of his home grand slam after an MRI scan on his knee revealed a cyst as a result of a small lateral meniscus tear.

He went under the knife on Monday and is now battling to be ready in time for the first Masters 1000 event of the season at Indian Wells, which starts on March 6.

"The surgery was a great success," Horsfall told Australian newspaper The Herald.

"We couldn't have been more pleased with the outcome of it. Now we will be pushing ahead for a speedy recovery and are aiming to see everyone at Indian Wells."

Kyrgios won the seventh ATP Tour singles title of his career in Washington last August and claimed the Australian Open men's doubles title with Thanasi Kokkinakis 12 months ago.

The 27-year-old, who has yet to play competitively this season, is a two-time quarter-finalist on the hard courts at Indian Wells.

Rafael Nadal ultimately emerged victorious in the match 7-6 (7-0) 5-7 6-4, after shaking hands with Nadal and the match umpire, Kyrgios spiked his racket into the ground as he walked back to his bench.

Speaking with post-match media, Kyrgios was sarcastic and rude when questioned about it.

"That's a question you're going to say after a three-hour battle against Nadal – that's what you've come here with?" he said.

"What would you like me to say about it? 

"Obviously was that my intention? No, because did I throw the racquet anywhere near him originally? It landed a metre from my foot and skidded and nearly hit him. I'm human. 

"Things happen like that obviously, it was a very misfortunate bounce. 

"What do you want me to say? It was three metres away from the kid.

The 2022 Wimbledon runner-up has not been in action this season, having been forced to pull out of the Australian Open in January due to a small lateral meniscus tear.

Kyrgios underwent surgery soon after and was targeting the opening Masters 1000 event of the season at Indian Wells for his first tournament back.

However, event organisers confirmed on Monday the 27-year-old is still not ready to return.

"Nick Kyrgios has withdrawn from the 2023 BNP Paribas Open due to an ongoing knee injury," a statement read.

Indian Wells gets under way on March 6 and is followed by the Miami Open at the end of the month.

Kyrgios' last competitive singles match came in October at the Japan Open, which he withdrew from ahead of the quarter-finals.

The Australian, a two-time quarter-finalist on the hard courts at Indian Wells, has slipped down to 19th in the ATP Rankings.

Medvedev beat his Czech opponent 6-3 6-2 in their second round match, his first since being told he cannot compete under the Russian flag following the invasion of Ukraine.

After saving a break point in the opening game, Medvedev settled quickly, breaking-to-love to go up 4-2 and securing the first set without conceding a point in his final two service games.

The 26-year-old effectively put the contest to bed when he broke Machac's serve in the opening game of the second set, later securing the double-break to sail to the finish line.

Speaking to the post-match media, Medvedev said it was far from a perfect performance, but was glad to come through unscathed.

"I think I was pretty consistent," he said. "If you look at the first set, it was pretty even. He made a few unforced errors and maybe some bad decisions in the crucial moments – that's how tennis is sometimes.

"The scoreline might be pretty effective, 6-3 6-2, but if you look at the points and the games, it was not as easy as it seems. 

The 2021 US Open champion triumphed 6-3 7-5 over the Spaniard in one hour and 44 minutes, securing his 18th straight victory.

Medvedev will face Frances Tiafoe in the semi-finals after the American beat Briton Cameron Norrie 6-4 6-4 in the other quarter-final in that half of the draw.

The Russian had suffered an ankle injury during Tuesday's last-16 win over Alexander Zverev but played on to clinch a hard-fought three-set win.

But Medvedev alleviated any injury concerns, although he required treatment on a bloody right thumb in the second set while escaping from 0-40 at 3-4.

"I'm actually happy the ankle didn't hurt much because when I warmed up, it was hurting pretty bad," Medvedev said post-match.

"I knew I was going to play, I knew I was going to try. But I couldn't move well on the warm-up. I tried to warm it up as long as possible, took one painkiller so that probably helped. I was actually feeling better and better during the match."

Medvedev raced to a 3-0 lead in the first set and never looked back, although Davidovich Fokina fought hard in the second frame but missed his big chance in the eighth game.

The pair both hit 24 winners for the match, but the Spaniard's 24 unforced errors compared to Medvedev's 12 was a key difference.

Tiafoe, who made last year's US Open last four, awaits after needing only one hour and 25 minutes to eliminate 2021 Indian Wells champion Norrie and reach his maiden ATP Masters 1000 semi-final.

Norrie had been on an eight-match winning run but the American hit 22 winners and only gave up nine unforced errors.

The governing bodies of tennis (the International Tennis Federation, ATP, WTA, and the four Grand Slam events) recently announced that Russian and Belarusian players can no longer compete under the flags of their respective countries.

Russia launched a full-scale military assault on Ukraine last month, a move that received the backing of Belarus, leading the ITF to revoke Russian and Belarussian membership and suspend the countries' teams.

That decision followed in the footsteps of rulings relating to Russian teams or competitors in various sports, including football and athletics.

Medvedev, who recently talked of his wish to "promote peace", said he hopes to continue to play, ahead of the first Masters event of the year in Indian Wells.

"It's always tough to talk on this subject because I want to play tennis, [to] play in different countries," the 26-year-old said.

"I want to promote my sport.

"I want to promote what I'm doing in my country for sure, and right now the situation is that that is the only way I can play [without representing Russia]."

Medvedev progressed to the quarter-finals for the first time at Indian Wells by coming from behind to defeat Zverev in three sets.

The 6-7 (5-7) 7-6 (7-5) 7-5 victory looked unlikely in the second set, when Medvedev hit the deck in obvious pain after turning his ankle.

It was subsequently taped by a physio, with Medvedev then coming through in three hours and 16 minutes, marking the longest three-set match of his career.

Medvedev has now won 17 matches in a row and is scheduled to face Alejandro Davidovich Fokina in the last eight.

But it is not yet clear whether he will be fit to play that match.

Speaking after the win over Zverev, Medvedev said: "When I twisted it, I thought I was going to stand up fine, then the pain started going fast, so I thought, 'oh no, that's not a good sign'.

"So, I honestly thought maybe one of the ligaments is a little bit injured, so I thought I'm not going to be able to play.

"That's probably one of the first times in my life where a physio taped my ankle, so I decided to give it a try, and it was very surprising. It was much easier to move and to run than to walk. When I was walking, I was limping, and then I was running fine.

"I can understand how frustrating it is for the opponent, but I was not faking it. It was tougher for me to walk.

"When the adrenaline goes down, the body cools down, it's going to be pretty painful, and I'm going to probably do a scan, see what it is and if I can continue to play."

Medvedev was beaten 4-6 6-3 6-1 by Frenchman Monfils, with the reigning US Open champion only able to connect on 50 per cent of his first serves, while he was broken three times in the decider.

For Monfils, the win earns him a spot in the fourth round against Carlos Alcaraz, while the loss means Medvedev will lose his position as world number one after only two weeks.

Speaking to post-match media, Medvedev said while he will work hard to earn the top-ranking back, starting in Miami next week.

"Is it better to be number one for, let’s say one week in your life, or never touch it?" he said. "I think it's still better to at least touch it.

"Now I know I'm going to lose it, so I have Miami to try to get it back. [I'm] usually feeling a little bit better in Miami in terms of tennis, so I'll try to play good there.

"I thought it could give me more motivation, well, I had motivation. It's just that I didn't find my best tennis."

The German, speaking ahead of the first Masters 1000 event of the year at Indian Wells, said his assault on the umpire's chair, for which he received a fine of $40,000 and a suspended eight-week ban from tennis, was a mistake he would not repeat.

The 24-year-old, who won the 2021 ATP Finals title last November, says he is still embarrassed by his actions in Mexico, having struck the umpire's chair with his racquet several times during a stunning outburst.

"It still is embarrassing for me now," Zverev said. "Walking around the locker room, it's not a nice feeling.

"But we all do mistakes. I'm also a human being, and I can guarantee you I will never act this way again in my life. 

"It was definitely the worst moment of my life."

Zverev will begin the Indian Wells Masters as the third seed, although world number two Novak Djokovic has been forced to withdraw from the competition due to his vaccination status.

The 24-year-old, who exited at the quarter-final stage of 2021's delayed edition of the tournament, says he has been working hard to avoid a repeat of his Acapulco meltdown and knows there is no room for error given his suspended ban.

"I've been doing work, meditation-wise," he said. "I think there are stress[ful] situations in everyone's life where stuff like this happens. I'm not the first and I won't be the last for something bad to happen on the court.

"I know who I am as a person, and this doesn't reflect me. I had played until 5am the day before – the same day I went back to play doubles.

"I am somebody that gives it his all on the court. I would have never physically harmed anyone.

"If I do that again, they have every right to ban me – it's as simple as that.

"If I do that again, it means I haven't learnt. I think everybody in life deserves a second chance, but if you repeatedly do mistakes it means that you haven't learnt."
