Alison Riske produced a breathtaking comeback to beat Garbine Muguruza at the Indian Wells Open, turning around an apparent lost cause after losing the first nine games of the match.

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.

Andy Murray chalked up a 700th career win with a typically gutsy performance to see off Taro Daniel in round one of the Indian Wells Masters.

Murray, 34, began slowly but ground out a 1-6 6-2 6-4 win over a player he has faced three times in the early stages of this season.

The former rankings leader has bounced back into the ATP top 100 after career-threatening injury woes and is looking to push on from number 88, his current position.

He will play 31st seed Alexander Bublik next.

Murray was delighted to reach the 700-win mark, telling Amazon Prime: "It means a lot. It's a target I set myself towards the end of last year. With everything that's gone on in the last few years, it's not been easy to get there.

"It's a great achievement; not loads of guys have been able to do that, so I'm really happy about it."

The three-time grand slam winner becomes the fourth active men's player to reach 700 wins, after Roger Federer, Rafael Nadal and Novak Djokovic.

Murray was beaten by Daniel in the second round of the Australian Open before avenging that in the Qatar Open.

The Scot has 14 titles to his name from Masters 1000 events but surprisingly has never triumphed at Indian Wells, and he was given a thorough workout by qualifier Daniel.

Daniel dashed into a 5-1 lead, striking the ball more cleanly and moving better than Murray, who has recently agreed to bring Ivan Lendl on to his team for a third time.

The Japanese star had no trouble seeing out that opening set, but the second was dominated by Murray.

Daniel then won the opening eight points of the decider to surge 2-0 ahead, but Murray broke back in the sixth game. Murray saved break point at 4-4 and made Daniel serve to stay in the contest. That proved beyond the 29-year-old, with Murray carving out three break points and taking the third of those when Daniel sent a forehand long.

Murray said he took pride from the match because he "figured it out" after being outplayed early on.

He said Lendl had wished him luck before going on court, with the pair to begin working together after Murray plays the next event in Miami.

Novak Djokovic is set to appear at next month's Monte Carlo Masters after his vaccination status left him unable to compete at Indian Wells.

The world number two has been forced to sit out the first Masters event of the year after not meeting the vaccination requirements to enter the United States, having been deported from Australia ahead of January's Australian Open for similar reasons.

Now, a post on the 20-time grand slam champion's official website suggests he will appear on the clay surface in Monaco, where the 34-year-old resides.

Monaco currently allows those who have recovered from COVID-19 in the previous six months to enter the city-state, with Djokovic claiming to have suffered from the virus in December.

"Novak will open his 2022 clay court season in Monte-Carlo, where he won the Masters 1000 title twice, in 2013 and 2015," the post reads.

The tournament now looks set to be the second to feature Djokovic in 2022 after he lost at the quarter-finals stage of last month's Dubai Tennis Championships.

The Monte Carlo Masters begins on April 10, lasting until April 17, and Djokovic will be looking to make amends after exiting last year's tournament to Dan Evans in the last 16.

Rafael Nadal, who overtook Djokovic for the most men's singles grand slam titles with his January triumph in Australia, holds the record for the most successes in Monaco, winning the tournament on 11 occasions.

Meanwhile, with France having loosened its travel restrictions for unvaccinated people this month, Djokovic will now hope to use the Monaco outing as preparation for a first grand slam appearance of the year at Roland Garros.

The Serbian now looks increasingly likely to be permitted to defend his 2021 French Open title in May after travel restrictions had originally cast doubt on his participation.

Wild card Nick Kyrgios admitted he was "pretty good" as he won in the opening round at the Indian Wells Masters over Sebastian Baez on Thursday.

The Australian cruised past Baez in one hour and 12 minutes, winning 6-4 6-0 to secure a second-round meeting with another Argentine, 32nd seed Federico Delbonis.

Kyrgios, who had not competed since January's Australian Open, was full of his typical flair, highlighted by 27-15 winners and 12-1 aces.

"When I play good, I'm pretty good," Kyrgios said after the match. "I'm just going back to basics."

Fabio Fognini made history in his 3-6 6-3 6-3 victory over Pablo Andujar, with his 392th career ATP win clocking up the most ever for an Italian, surpassing Adriano Panatta.

Compatriot Lorenzo Musetti also progressed on Thursday with a 6-3 7-5 win over American Marcos Giron.

Rising American talent Jenson Brooksby defeated Roberto Carballes Baena 6-1 6-4, while countryman and wild card Jack Sock brushed aside Juan Manuel Cerundolo 6-1 6-1 in little over an hour.

Pedro Martinez made light work of Joao Sousa 6-4 7-5, while Tomas Machec got past Alexei Popyrin 6-3 7-5.

Naomi Osaka produced a spirited performance as she defeated Sloane Stephens in three sets at Indian Wells on her return to the court.

Osaka was in action for the first time since a shock early exit at the Australian Open in January, but she ultimately had too much for Stephens in a 3-6 6-1 6-2 success.

Stephens initially looked the sharper of the two former major champions in the second-round clash, impressively taking a first-set lead, but Osaka found her groove after a slow start to level the contest.

Osaka then had to save three break points at 2-0 down in the decider, and that appeared to inspire another surge as she rattled off six successive games to roar to an emphatic win.

Shelby Rogers got past Nuria Parrizas-Dias in almost three hours, winning 6-1 5-7 7-6 (7-3), and last week's Monterrey Open runner-up Camila Osorio retired down 6-4 5-0 against Aliaksandra Sasnovich.

Yulia Putintseva got past Ashlyn Krueger 6-3 6-2 and Ukraine's Marta Kostyuk won in three hours and nine minutes over Maryna Zanevska 6-7 (5-7) 7-6 (8-6) 7-5.

Last month's Abierto Zapopan runner-up Marie Bouzkova eased past China's Wang Qiang 6-3 7-6 (7-5), while American Amanda Anisimova defeated compatriot Emma Navarro 6-2 6-2.

World number three Alexander Zverev claims his expulsion from last month's Mexican Open in Acapulco represented the worst moment of his life.

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."

World number one Daniil Medvedev hopes that Russian and Belarusian tennis players will be allowed to continue competing but acknowledges there remains a chance of further restrictions.

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]."

Caroline Garcia reached the second round of the Indian Wells Open after coming through a gruelling encounter with Dayana Yastremska.

Garcia had gone three matches without a win against her Ukrainian opponent, who reached the final of last week's Lyon Open.

Although she squandered two match points in the second set, Garcia eventually prevailed 6-4 6-7 (8-10) 7-5 after nearly two and a half hours to set up a second-round clash with US Open champion Emma Raducanu.

Sofia Kenin's difficult start to the year continued as she suffered a straight-sets defeat to Brazil's Beatriz Haddad Maia.

The Australian Open champion and French Open runner-up two years ago, Kenin has now lost six matches in a row since reaching the quarter-finals in Adelaide back in January.

The 23-year-old, who has dropped to 130 in the world, threw in 11 double faults in her 6-3 7-5 defeat to Haddad Maia, who next meets 29th seed Clara Tauson.

Ekaterina Alexandrova will face Simona Halep, the 2015 champion, in round two after coming through 4-6 6-2 7-6 (9-7) against 18-year-old American Elvina Kalieva.

There were also wins for Kaia Kanepi, Alison Riske and Harriet Dart, who next meets 12th seed Elina Svitolina.

World number 37 Jil Teichmann lost in straight sets to Danka Kovinic, Ann Li beat compatriot Madison Brengle in an all-American thriller, and wildcards Katie Volynets and Claire Liu also progressed.

Novak Djokovic has confirmed he cannot compete at Indian Wells due to not being allowed to enter the United States.

The former world number one was revealed as an automatic qualifier for the BNP Paribas Open at Indian Wells last month, though uncertainty surrounded his possible participation.

Djokovic was deported from Australia ahead of the Australian Open in January due to not meeting the country's COVID-19 vaccination requirements, with the Serbian choosing not to be jabbed.

After testing positive for – and recovering from – coronavirus the previous month, it was at one stage thought Djokovic might have been allowed entry to Australia on the grounds of having post-virus antibodies.

But he was ultimately ordered to leave the country and it quickly became clear the 34-year-old was likely to run into similar problems down the line.

Djokovic was included in the draw for the upcoming BNP Paribas Open, setting up a second-round clash with David Goffin or Jordan Thompson, and organisers said on Wednesday that talks were ongoing as they looked to determine the superstar's eligibility.

But America's Centers for Disease Control and Prevention (CDC) states all non-US citizens travelling to the country "must be fully vaccinated with the primary series of an accepted COVID-19 vaccine", with "only limited exceptions" applying.

Unsurprisingly, Djokovic has not been granted entry.

Confirming his situation, Djokovic tweeted: "While I was automatically listed in BNP Paribas Open and the Miami Open draw, I knew it would be unlikely I'd be able to travel.

"The CDC has confirmed that regulations won't be changing so I won't be able to play in the US. Good luck to those playing in these great tournaments."

Djokovic has lost his place atop the ATP rankings to Daniil Medvedev and his inability to feature at the Australian Open meant Rafael Nadal set a new record for the most grand slam men's singles titles, as the Spaniard claimed his 21st success.

It is unclear whether Djokovic will be able to add to his 20 at Wimbledon or Roland Garros, while it seems he will also miss the US Open unless the CDC changes its regulations in the meantime.

Novak Djokovic is at the centre of another saga after being included in the draw for the BNP Paribas Open at Indian Wells.

The former world number one was handed a second-round clash against either David Goffin or Jordan Thompson.

All 32 seeds receive a first-round bye, so although the men's singles begins on Thursday at the California desert event, Djokovic is not due to be in action until the weekend.

However, it remains to be seen whether he is allowed into the United States, given he has declared he has not received any vaccination against the COVID-19 virus.

Tournament organisers admit they do not know whether Djokovic will play.

They said in a statement on the event's official Twitter feed: "Novak Djokovic is on the tournament entry list, and therefore is placed into the draw.

"We are currently in communication with his team; however, it has not been determined if he will participate in the event by getting CDC approval to enter the country.

"We will provide updates in the future as we learn more."

The CDC is America's Centers for Disease Control and Prevention, which lays down requirements for non-US international citizens travelling to the United States.

Within its rules, it is stated that all non-US citizens travelling to the US "must be fully vaccinated with the primary series of an accepted COVID-19 vaccine", adding that "only limited exceptions apply".

Djokovic tested positive for COVID-19 in December, and at one stage it appeared that recovering from that, and having post-virus antibodies, would be enough to allow him to travel to Melbourne and play in the Australian Open.

That proved not to be the case, with Djokovic twice detained after arriving in Australia before being deported.

He has since made his return to tennis at the Dubai Tennis Championships, where he surprisingly lost in the quarter-finals to Jiri Vesely.

The 34-year-old Serbian has been overtaken for the rankings top spot by Daniil Medvedev, the Russian who will be playing under a neutral flag while his country's military invasion of Ukraine continues. Medvedev will begin against Alexei Popyrin or a qualifier at Indian Wells.

Naomi Osaka has been handed a difficult first round draw against 2017 US Open winner Sloane Stephens upon her return to the WTA Tour at Indian Wells which starts on Wednesday.

Four-time major winner Osaka has not played competitively since her 2022 Australian Open third-round exit to Amanda Anisimova in January.

The Japanese, whose ranking has dropped to 78th, had been handed a wild card for Indian Wells but was upgraded to the main draw after Camila Giorgi's withdrawal.

The Indian Wells draw was made on Monday with Osaka to face Stephens who won her first WTA title since 2018 with last month's Abierto Zapopan crown.

The top seeds all have been waived through to the second round with top seeds Barbora Krejcikova and Aryna Sabalenka book-ending the draw.

Novak Djokovic has said he cannot currently enter the United States, putting his participation in next month's Indian Wells Masters in doubt.

Djokovic won his first match back on the ATP Tour since missing the Australian Open on Monday, beating Lorenzo Musetti in the round of 32 at the Dubai Tennis Championships.

The men's world number one had not played a competitive match since early December and was last month deported from Australia on the eve of the Australian Open.

That decision was a result of Djokovic opting not to join the majority of his tennis peers in getting vaccinated against COVID-19 and amid controversy over how he handled getting the virus himself in December.

He showed no signs of rust as he eased to a 6-3 6-3 win over Musetti in just 74 minutes in his first match of 2022, hitting five aces, winning an impressive 71 per cent of his second serves (17 out of 24) and saving all seven break points he faced against his Italian opponent.

However, at a press conference following his victory, Djokovic admitted he is currently unable to enter the United States, and is therefore on course to miss March's prestigious Indian Wells Masters tournament.

"As of today, not. I can't go, I can't enter the United States," he said.

"As of today I'm not able to play. But let's see what happens. I mean, maybe things change in the next few weeks."

Djokovic has been included on the entry list for Indian Wells despite the tournament requiring all players are vaccinated against COVID-19.

Images of Djokovic do not appear in any of the tournament's build-up social media posts nor on the website's promotional announcement, while his entry-list inclusion was little more than a footnote – though did include him.

The statement read: "A power-packed line-up of ATP top-10 players will join [Rafael] Nadal in looking to put together a breakthrough performance in Tennis paradise.

"2021 US Open champion and 2022 Australian Open finalist Daniil Medvedev (world no. 2), 2021 ATP Finals winner Alexander Zverev (world no. 3), and 2021 French Open finalist Stefanos Tsitsipas (world no. 4) will each be in search of their maiden title in the desert.

"Reigning BNP Paribas Open champion Cameron Norrie (world no. 13) will look to replicate his extraordinary 2021 title run, in which he won his first Masters 1000 crown.

"World no. 1 and five-time Indian Wells champion Novak Djokovic is also on the tournament entry list."

Paula Badosa denied Victoria Azarenka a slice of WTA Indian Wells Open history as the former world number one failed to become the first three-time winner of the singles event after defeat in Sunday's gruelling final.

Azarenka, also a winner in 2012 and 2016, had to come back from a set and a break down in the semi-final, and for a while looked like good preparation for the battle that Badosa provided.

But in the end Badosa prevailed 7-6 (7-5) 2-6 7-6 (7-2) after three hours, four minutes on court, securing only her second title in what was just her second final of the season while becoming the first Spanish woman to claim the title in Indian Wells.

A highly competitive start saw a combined total of nine break points go to waste in the first four games alone, and when Azarenka did finally lose a service game to go 4-3 down, she emphatically hit back at the first time of asking.

She had no option but to repeat that feat soon after when Badosa broke again to take a 6-5 lead, and she duly obliged to set up a tie-break.

But Badosa got the better of two-time grand slam champion Azarenka in the tie-break, despite the latter overturning a four-point deficit to go level at 5-5.

Azarenka appeared re-energised at the start of the second set, though, charging into a 3-0 lead inside 11 minutes, her level of intensity suddenly leagues ahead of her opponent's.

Badosa only showed brief glimpses of her ability and Azarenka had few issues levelling the match, her class on full display in the fifth game as she read a wide drop shot and replied with a sensational cross-court effort.

After such a colossal fight to get back on level terms it was perhaps to be expected that Azarenka would drop off a little early on in the decider, but a bad miss from Badosa allowed the Belarussian to recover from a break and she consolidated to tie the set at 2-2.

The pair continued to slog it out thereafter with neither woman giving an inch, Badosa's often-brutal power countered nicely by Azarenka's athleticism.

But Badosa was her own worst enemy as she overhit two shots to allow Azarenka to get what looked likely to be the decisive break, but the 32-year-old failed to serve out the match and, perhaps predictably, a tie-break ultimately beckoned.

Badosa's energy reserves suddenly looked far deeper than her opponent's as she moved her around the court with almost surgical precision, her eventual 7-2 win in the tie-break speaking to the ferocity she displayed to win the comfortably biggest title of her career to date.

Garbine Muguruza could not keep the momentum going at the Indian Wells Open after winning a WTA title last week and the former world number one was followed out the door by Maria Sakkari.

Muguruza, who claimed the Chicago Fall Tennis Classic, was surprisingly upstaged 6-3 1-6 6-3 by Australia's Ajla Tomljanovic in an upset on Saturday.

Tomljanovic had been 0-6 against top-10 players this year heading into the match but had just enough to edge the fifth seed and two-time grand slam champion with some timely breaks of serve. 

The world number 47 Tomljanovic is into the third round at Indian Wells for the first time in seven appearances and next faces 26th seed Tamara Zidansek. 

"I was really looking forward to playing Garbine, because I did lose [to her] the last couple of times," Tomljanovic said in her on-court interview. "I did try to focus on that one time I beat her [in 2014], and tried to channel that energy, so I was really happy that I got through today."

GOLUBIC STUNS SAKKARI

Sixth seed Sakkari – a semi-finalist at this year's French and US Opens – also fell victim to a shock result, going out 5-7 6-3 6-2 to Viktorija Golubic in their first meeting. 

The pair kept trading service breaks in the opening set, five in all, before Golubic tightened up her game for the final two sets. 

After breaking the Swiss three times in the first set, Sakkari converted just one of four break points the rest of the match. 

Golubic had lost in the first round in her previous two trips to Indian Wells but is now on to the third, where she will face Anna Kalinskaya.

ANDREESCU HOLDS OFF RISKE

Former US Open champion Bianca Andreescu saw a potential straight-sets win slip away before recovering to defeat Alison Riske 7-6 (7-2) 5-7 6-2.

Andreescu – the defending champion after the 2020 WTA Premier 1000 event was cancelled due to the coronavirus pandemic – led 4-1 in the second set but watched her advantage evaporate as Riske forced a decider, which the Canadian ended up taking comfortably as she faced only one break point in the last. 

Top seed Karolina Pliskova eased past Magdalena Frech 7-5 6-2, while third-seeded Barbora Krejcikova was pushed to a third set before prevailing 6-4 3-6 6-1 against Zarina Diyas. 

Angelique Kerber – the 10th seed and three-time major winner – went the distance to beat Katerina Siniakova 6-1 6-7 (4-7) 7-5, while 15th seed Coco Gauff downed Caroline Garcia 6-3 6-7 (2-7) 6-1 in her debut match at the tournament. 

Ons Jabeur, the 12th seed, prevailed 6-2 6-7 (5-7) 6-3 over Anastasija Sevastova and 18th seed Anett Kontaveit – Andreescu's next opponent – moved on when Martina Trevisan retired down 6-3 5-2. 

US Open champion Emma Raducanu is refusing to be downcast after her defeat to Aliaksandra Sasnovich, insisting that she is focused on "the bigger picture".

The 18-year-old's 10-match winning run came to an abrupt halt at the Indian Wells Open – just her fifth tour-level event – as Sasnovich won in straight sets.

Sasnovich is ranked 100th in the world, but the 27-year-old has 16 career victories over opponents in the top 20, with Raducanu ranking 17th, and six over those in the top 10.

Raducanu cites the experience gap between herself and Sasnovich as a major factor in her defeat and believes that the loss can be taken as a positive lesson.

"I'm still very, very new to the tour," Raducanu said. "I think that experience just comes from playing week in, week out and experiencing all these different things. I'm kind of glad that what happened today happened, so I can learn and take it as a lesson so going forward I'll just have more experienced banked.

"[Sasnovich's] been on tour, probably been 4-2 down like hundreds of times whereas I've been 4-2 up... it's my third WTA tournament this year. [Experience] will come in time. Just got to not rush it and keep going and get my head back to the drawing board really.

"I didn't go in there putting any pressure on myself because in my mind I'm so inexperienced that I'm just taking it all in. You're going to have highs, and you're always going to have some lows where you're disappointed with how you performed.

"Aliaksandra played an extremely great match. You could tell she's more experienced than me. She went out there and executed her game plan better than I did. She deserved to win that.

"I think it's going to take me time to adjust, really, to what's going on. For the bigger picture, I'll be thanking this moment. That's the lesson I think, that you can easily get sucked into being so focused on the result and getting disappointed."

Raducanu is set to take part at the Transylvania Open that starts on October 25, as well as the Kremlin Cup in Moscow.
