Novak Djokovic has been ruled out of the Miami Open after tournament organisers "exhausted all the options" in an effort to secure him a travel exemption.

The 22-time grand slam winner withdrew from the Indian Wells Open as he is unable to play in the United States.

He is not vaccinated against COVID-19, which remains a requirement of international travellers, but Djokovic had hoped to be granted special permission to enter the country.

US tennis authorities and a number of politicians also expressed support for an exception being made for the 35-year-old Djokovic, with US president Joe Biden urged to reconsider policy.

Even last week, Serbian superstar Djokovic was clinging to hopes of playing the Miami Open, which he has won six times.

However, tournament director James Blake told Tennis Channel there is no chance of that happening, despite extensive efforts.

"Obviously, we're one of the premier tournaments in the world, we'd like to have the best players that can play," said Blake, a former world number four.

"We did all that we could. We tried to talk to the government, but that's out of our hands. We tried and he wasn't able to play."

Blake said he was in the same position as Indian Wells tournament director Tommy Haas, being unable to influence government-level decisions.

"We tried to get Novak Djokovic to be allowed to get an exemption, but that wasn't able to happen," Blake said. "We'd love to have him, and he’s our greatest champion, won it six times here.

"Unfortunately, that's way above my pay grade."

Blake added: "We exhausted all the options we knew of. Hopefully Novak will be back this year and hopefully he will be back for all the later events in the States including Cincinnati and the US Open."

World number two Carlos Alcaraz is through to the Indian Wells Open semi-final after defeating 11th seed Felix Auger-Aliassime 6-4 6-4 on Thursday.

Alcaraz, 19, continued his terrific start to 2023, now boasting 12 wins from his first 13 matches of the year after winning the Argentina Open and reaching the Rio Open final.

But despite the Spaniard's status as the game's top young talent, he came into the contest winless in his three previous meetings against Canada's Auger-Aliassime.

What separated the two this time around was Alcaraz's ability to keep the ball in play. He produced 26 winners with only eight unforced errors, and while Auger-Aliassime was not much worse (24 winners, 13 unforced errors), he committed six double faults.

He is now one match away from reaching the third Masters 1000 final of his career, having won both the Miami Open and the Madrid Open this past season.

Meeting him in the semi-final will be Italy's Jannik Sinner after he prevailed 6-4 4-6 6-4 against hometown hero Taylor Fritz.

In the seesawing contest, Sinner narrowly edged the total point count 94-86 – with both committing exactly 17 unforced errors – but the Italian created nine break point chances compared to Fritz's three.

Since the beginning of the Australian Open, Sinner sports a 14-2 record, with the only losses in that span coming against world number three Stefanos Tsitsipas and world number six Daniil Medvedev.

It will be the sixth meeting between Sinner and Alcaraz, with the Spanish teen taking in a 3-2 edge after a five-set thriller at the US Open.

Top seed Iga Swiatek had little trouble navigating the challenge of Sorana Cirstea in Thursday's Indian Wells Open quarter-final, cruising to a 6-2 6-3 victory.

The world number one started brilliantly by breaking the unseeded Romanian's serve on her first opportunity, and despite Cirstea responding, Swiatek rattled off the final four games of the opening set.

The 21-year-old Polish phenom would not stop there as she continued on a streak of eight consecutive games to jump ahead 4-0 in the second set, finishing the job in 83 minutes.

It is Swiatek's third consecutive tournament where she has made it to at least the semi-finals, having won the Qatar Open and reached the final of the Dubai Tennis Championships in February.

The last time she did not reach the semi-final in a tournament was in January's Australian Open, when she was sent packing in the fourth round by Elena Rybakina.

She will get a chance to avenge that defeat in the semi-final after Rybakina set up the rematch by getting the better of Karolina Muchova 7-6 (7-4) 2-6 6-4.

Rybakina, who became the first Kazakhstan-born player to reach the semi-final of a WTA1000 event since 2009, had a much more competitive affair. 

In the razor-thin battle, both Rybakina and Muchova won exactly 106 out of 212 points, but the reigning Wimbledon champion and Australian Open finalist produced 14 break point opportunities to the Czech's six.

It will be the fourth overall meeting between Swiatek and Rybakina, and after the Pole took their first clash, Rybakina responded with back-to-back straight-sets victories.

The winner will earn a spot in the final, where they will meet the victor of Maria Sakkari and Aryna Sabalenka.

Maria Sakkari prioritised a pedicure after earning a shot at Australian Open champion Aryna Sabalenka in the Indian Wells Open semi-finals.

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."

Australian champion Aryna Sabalenka made light work of sixth seed Coco Gauff in a dominant straight-sets win to clinch her spot in the Indian Wells Open semi-finals on Wednesday.

Sabalenka improved her 2023 season record to 16-1 with a 6-4 6-0 win over the 19-year-old American in only 65 minutes.

The Belarusian will face seventh seed Maria Sakkari in the semi-finals after the Greek edged out 15th seed Petra Kvitova in three sets in the evening quarter-final.

Sabalenka will be tough to beat, however, maintaining her strong season form against Gauff who had little answers despite boasting a 3-1 head-to-head record coming into the clash.

The second seed crushed 18 winners compared to Gauff's 12, while she committed 14 fewer unforced errors across the match.

Sabalenka opened up a 2-0 lead in the first set and maintained that buffer to take the opening frame, before a 25-minute second-set bagel underlined her dominance.

"I feel a little bit different on the court this year," Sabalenka said after the match. "I feel like I'm a little bit different player. I wasn't really focusing on the last matches against her. I was focused on myself."

Sakkari came from behind to defeat two-time Wimbledon champion Kvitova 4-6 7-5 6-1 in two hours and 17 minutes.

The Greek, who finished as last year's Indian Wells Open runner-up, was broken twice in the first set and dropped serve again in the opening game of the second frame, before finding a way to flip the match on its head.

Sakkari broke back for 3-3 in the second set, winning 12 of the final 15 games for victory in an impressive turnaround. All four of Sakkari's matches in Indian Wells this fortnight have gone to three sets.

Fifth seed Daniil Medvedev brushed off an ankle concern and booked his spot in the Indian Wells Open semi-finals after a straight-sets win over Alejandro Davidovich Fokina on Wednesday.

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.

Coco Gauff celebrated her 19th birthday by releasing a newly discovered video of herself singing and dancing at the US Open 11 years ago.

Gauff could not let loose quite the same this week, as she battled through to the Indian Wells Open quarter-finals on Tuesday, coming back in the decisive set to beat Rebecca Peterson 6-3 1-6 6-4.

The world number six will be hoping to remain unbeaten as a 19-year-old when she faces second seed Aryna Sabalenka in California, where a win for the home favourite would have everyone jumping for joy like in 2012, when Gauff was filmed singing and dancing to Carly Rae Jepsen's hit single Call Me Maybe at Flushing Meadows.

"I think that was the only Kids' Day," Gauff recalled.

"But I remembered it because Call Me Maybe was trending, and I knew that video existed.

"I thought that my mom would have it because she keeps track of everything, but it was really my dad who has it, so that's why we never found the video because I never thought to ask him."

An eight-year-old Gauff at the Arthur Ashe Stadium would have had no idea that she would reach the competition's quarter-finals just a decade later, and she is now ranked seventh in the world.

Her rise has continued at Indian Wells, with a last-eight appearance already her best-ever run in the event.

Gauff added: "I just love that video and just the whole full-circle moment.

"Call Me Maybe was the song at that time. Even now I still love when they play it.

"I don't know whose number I was trying to get, I think I was eight years old. But I'm going to use that pickup line now!"

Emma Raducanu conceded there is "a long way to go" until she is back to full fitness but remained "proud" of her week at Indian Wells despite her fourth-round defeat to Iga Swiatek. 

Raducanu had been plagued by tonsillitis and a recurring wrist injury in the build-up to the tournament that forced her to pull out of a doubles exhibition with Cameron Norrie on the eve of the competition. 

The 20-year-old was able to compete in the women's draw, however, and claimed victories over Australian Open semi-finalist Magda Linette and world number 13 Beatriz Haddad Maia before losing 6-3 6-1 to world number one Swiatek on Tuesday.

Raducanu started well but a fourth match in six days eventually caught up with the Brit, who lost the second set comprehensively.

Yet Raducanu is satisfied with her performances in her first tournament appearance since January.

"I'm very proud of myself," Raducanu said.

"I think I had a few good wins earlier against some great opponents. I did two good training weeks in London. They paid off to an extent but ultimately two weeks of training isn't going to cut it against the world number one right now. 

"Now it's just about consistent work to physically get to where I want to be. I saw a taste of the level where number one is at physically and how she is at the corners, repetitive, relentless. Yeah, I just couldn't take that." 

"I'm looking forward to playing her after I've got more time under my belt."

Raducanu will now return to training as she looks to build on her most impressive set of displays since her remarkable US Open victory in 2021, with the Miami Open next on the cards.

She added: "Physically I feel like that's going to be one of my biggest assets. I think that I'm going to be one of the best athletes on the tour, and that's going to be a big part of my game. 

"I would say there is a very long way to go, but I'm definitely starting the right work now."

Reigning champion Swiatek will now face Sorana Cirstea in the quarter-finals.

"I'm always pretty good in defence. I knew that I can't rush it and I can't be not patient, so I just stayed solid and I wanted to choose the right directions," Swiatek said after becoming the sixth player to win 11 or more of her first 12 main draw matches at Indian Wells.

"I always want to finish points as fast as possible if I have a chance, but for sure I know that sometimes it's not going to be possible here."

Iga Swiatek has called for more to be done to help Ukrainian players following Lesia Tsurenko's withdrawal from the Indian Wells Open due to a panic attack.

Ukrainian Tsurenko had been due to face Belarusian Aryna Sabalenka in the third round on Sunday, only to pull out for what had initially been put down to "personal reasons".

She later revealed her decision was down to a panic attack triggered by a chat with WTA chief executive Steve Simon about tennis's response to Russia's invasion of Ukraine.

Swiatek offered her full support to Tsurenko and wants more focus to be on Ukrainian players during a hugely challenging period, rather than on Russian and Belarusian players.

"I totally understand why she withdrew. I respect Ukrainian girls so much," said the world number one, speaking after her 6-3 6-1 win over Emma Raducanu in the last 16 on Tuesday.

"If a bomb landed in my country or if my home was destroyed, I don't know if I could handle that and compete.

"You have to really mentally be there to compete every week. So I get that she wasn't ready to do that.

"I feel more should be done to help Ukrainian players. Everything we discuss in tennis is about Belarusians and Russians, if they should be allowed, what's going on with them.

"I don't think that's right. We should focus more on helping Ukrainian players and providing them with everything they need.

"They basically have to take care of all their families, and there's a lot of baggage on their shoulders."

Swiatek, who wears a Ukrainian flag on her cap, called out Anastasia Potapova earlier this week after she wore a Russian football shirt on court at Indian wells.

Potapova, allowed to compete in events as a neutral athlete, sported a Spartak Moscow jersey ahead of her 6-3 4-6 5-7 defeat to Jessica Pegula on Monday.

"To be honest, I was surprised," Swiatek said. "I thought the player realised that she should not, even if she is a fan of the team, show her views in this way at such times."

Top seed Swiatek believes the situation could have been avoided had the WTA set out clear guidelines regarding the highly charged political situation.

"It's a tough situation. It's pretty emotional as I feel like these situations with people wearing Russian football shirts because we didn't have proper leadership," Swiatek said.

"There is a lot of tension in the locker room that is obviously going to be there, because there is a war. 

"But maybe there would have been a little bit less [tension] if WTA put some action in place at the beginning to kind of explain to everybody what is right and what is not."

Swiatek resumes her Indian Wells title defence against Sorana Cirstea in the quarter-finals on Thursday.

Top seed Carlos Alcaraz moved into the Indian Wells Open quarter-finals after Jack Draper retired down 6-2 2-0 due to an abdominal injury in their last-16 clash on Tuesday.

Alcaraz was in control, winning the first set in 36 minutes before racing to a 2-0 lead inside 10 minutes before the Briton withdrew. Draper had battled the injury in the latter stages of Monday's win over Andy Murray.

Despite that, the Spaniard looked in good touch, setting up a quarter-final meeting with eighth seed Felix Auger-Aliassime, who has a 3-0 head-to-head record against him.

"I felt the ball really well. I'm really happy with that part," Alcaraz said. "I would say I returned well, I hit great shots. I finished the match with confidence in my shots, to come into the next round with more confidence."

Auger-Aliassime saved six match points in a dramatic triumph over 17th seed Tommy Paul to reach the last eight, winning 3-6 6-3 7-6 (8-6) in two hours and 48 minutes.

The Canadian trailed 0-40 on serve at 5-6 in the deciding set before winning the next five points. He repeated that feat, down 3-6 in the tie-break, capitalising on his first match point. Auger-Aliassime hit 31 winners for the match, along with 51 unforced errors.

Fifth seed Daniil Medvedev fought back from a set down and a rolled ankle to progress past Alexander Zverev 6-7 (5-7) 7-6 (7-5) 7-5 in three hours and 10 minutes.

Medvedev rolled his ankle in the sixth game of the second set, going down in pain but played on, in his longest-ever three-set match. The victory is the Russian's 17th in a row. Zverev committed 50 unforced errors across the match.

The Russian will take on Alejandro Davidovich Fokina in the last eight, with the Spaniard winning 6-3 6-4 over Chilean qualifier Cristian Garin.

Jannik Sinner cruised past Stanislas Wawrinka 6-1 6-4 in one hour and 39 minutes to move into the last eight where he will face reigning champion Taylor Fritz. The American won 6-4 6-3 over Hungary's Martin Fucsovics in one hour and 41 minutes.

British 10th seed Cameron Norrie will play 14th seed Frances Tiafoe in the other quarter-final, with the former winning 6-2 6-4 over the higher-ranked Andrey Rublev. Tiafoe won 6-4 6-4 over Alejandro Tabilo in 83 minutes for his 150th career win.

Top seed Iga Swiatek will be hard top stop in her title defence at the Indian Wells Open after a straight-sets thrashing over Emma Raducanu in Tuesday's last 16.

The Polish world number one eased to victory 6-3 6-1 in one hour and 25 minutes over the 2021 US Open champion, who has enjoyed an improved run this week in California.

Swiatek offered few weaknesses in a strong disciplined display, converting four of 10 break points, including three in a one-way second set.

The three-time major winner won 88 per cent on her first serve while she was impressive on return and able to win the longer rallies. Swiatek hit 22-9 winners while Raducanu made 22-14 unforced errors.

Swiatek will take on Romania's Sorana Cirstea in the quarter-finals, after she upset fifth seed Caroline Garcia 6-4 4-6 7-5 in two hours and 24 minutes.

Reigning Wimbledon champion Elena Rybakina also progressed in that part of the draw, setting up a last-eight clash with unseeded Czech Karolina Muchova.

Rybakina won 6-3 6-0 over qualifier Varvara Gracheva in a similarly strong performance, needing only one hour and 21 minutes.  Muchova beat compatriot Marketa Vondrousova 6-4 6-7 (2-7) 6-4 in two hours and 37 minutes.

Third seed Jessica Pegula was the major casualty of the day's play, going down 6-2 3-6 7-6 (13-11) to 16th seed Petra Kvitova in a dramatic two-hour-and-16-minutes clash.

Pegula had opened up a 5-3 third-set lead and squandered a match point on serve, before two-time Wimbledon winner Kvitova squared it up at 5-5. Kvitova, however, was broken immediately to offer Pegula another chance to serve out the match again, which she was unable to take.

The American generated another three match points in the tie-break but could not convert before the Czech eventually prevailed on her own fourth match point, with the deciding set lasting one hour and 12 minutes.

Kvitova will face seventh seed Maria Sakkari in the quarters after she triumphed in a lengthy clash 6-4 5-7 6-3 over Karolina Pliskova, lasting two hours and 43 minutes.

Second seed Aryna Sabalenka also needed three sets to beat Barbora Krejcikova 6-3 2-6 6-4 in two hours and four minutes. Krejcikova had been responsible for Sabalenka's lone loss this season, in a 15-1 year.

Sabalenka, who won this year's Australian Open, will face sixth seed Coco Gauff who defeated Rebecca Peterson 6-3 1-6 6-4. Gauff won the last four games for victory, having trailed 4-2 in the deciding set.

Daniil Medvedev expects to have a scan on his right ankle to see if he can continue his Indian Wells Masters campaign after injuring it in defeating Alexander Zverev.

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."

Carlos Alcaraz felt "really proud" to complete 100 wins at ATP Tour level while still a teenager as the world number two marched on at the Indian Wells Open.

Only John McEnroe has reached a century of victories in fewer matches, the ATP said, with the American getting there from 131 contests while it took Alcaraz 132 to get to that landmark.

Alcaraz made it 10 wins from 11 matches in 2023 by defeating Tallon Griekspoor 7-6 (7-4) 6-3 on Monday at the California tournament.

The Spanish prodigy last year won the US Open and in doing so became the youngest men's world number one, with Novak Djokovic having since clawed back top spot.

Victory over Griekspoor made Alcaraz the third men's tour player born after 2000 to claim 100 tour wins, after Jannik Sinner and Felix Auger-Aliassime, said OptaAce.

The youngster's first tour-level win came against fellow Spaniard Albert Ramos-Vinolas at the 2020 Rio Open, with the then 16-year-old wrapping up a 7-6 (7-2) 4-6 7-6 (7-2) at 3am local time.

The latest victory was his 24th at ATP 1000 level, going past Djokovic on the all-time ranking for wins at that elite tier by players before turning 20.

Alcaraz trails Denis Shapovalov (25) and Rafael Nadal (49), in that regard, but the chances are he will soon only trail Nadal, whom he cannot catch.

With his 20th birthday coming up in May, Alcaraz can substantially add to his ATP 1000 wins before leaving behind his teenage years. He will be looking to go further at Indian Wells and then rack up more victories in Miami, Monte Carlo and Madrid.

He will turn 20 on May 5, during the Madrid tournament where he is the defending champion.

Reflecting on his time on tour so far, Alcaraz said: "A lot has happened since that first ATP win. I'm really proud of myself to have my 100th win on the tour, in like 132 matches.

"I saw I was the second player in history with less matches to be able to get to 100 wins. I'm really proud of myself about that."

Alcaraz has a win percentage of 70.6 at ATP 1000 events in his fledgling career. Only three players with 10 or more matches in ATP 1000 events as a teenager have a higher percentage of success: Andre Agassi (90.9 per cent), Rafael Nadal (84.5) and Jim Courier (72.7).

Standing in the way of Alcaraz making an immediate improvement to his record is another emerging young talent, the 21-year-old British player Jack Draper.

They will meet in round four at Indian Wells on Tuesday, with Draper having sunk the hopes of compatriot and three-time grand slam winner Andy Murray on Monday to reach that stage.

"I know he's a really good player," said Alcaraz, who won his one previous meeting with Draper, a tight three-setter in Switzerland last year.

"I mean, he's playing well. He has beaten great opponents like [Dan] Evans and Andy. I know that I'm going to have to play my best, give my 100 per cent on court. I played against him in Basle [and won] 7-5 in the third, I think. It's going to be a really tough match and I'm going to enjoy it."

World number two Carlos Alcaraz made it 10 wins from 11 matches in 2023 after defeating Tallon Griekspoor 7-6 (7-4) 6-3 in round three at the Indian Wells Open.

Alcaraz, 19, kicked off his 2023 campaign with eight wins in a row, including an Argentina Open title, before losing to Cameron Norrie in the Rio Open decider.

He has yet to drop a set at this fortnight's tournament in California, following up his opening win over Thanasi Kokkinakis with another strong showing against 31st seed Griekspoor.

The Spaniard will look to keep his strong form going when he meets Jack Draper in the fourth round, after 21-year-old Draper prevailed 7-6 (8-6) 6-2 in a battle of the Brits against Andy Murray.

Murray, who came into the match with six wins from his past seven outings, had an opportunity to take the match by the scruff of the neck but could not capitalise on a set point before going down in a tight tie-break, before Draper took charge.

California's own Taylor Fritz lived up to his fourth seeding, with the defending champion having little trouble in overcoming Argentina's Sebastian Baez 6-1 6-2, and he will play Hungary's Marton Fucsovics for a spot in the quarter-final.

Fucsovics, after upsetting 16th seed Alex De Minaur in the previous round, got the better of Slovakia's Alex Molcan 6-4 6-2.

Former world number three Stan Wawrinka showed he still has some gas in the tank after a surprise 6-2 6-7 (5-7) 7-5 triumph over world number eight Holger Rune, with the 37-year-old showing what he has learned through competing at the top level for as long as the 19-year-old Dane has been alive.

Jannik Sinner, the 13th seed, successfully navigated the challenge of veteran Adrian Mannarino for a 7-6 (9-7) 6-4 victory, Tommy Paul won his top-20 showdown against Hubert Hurkacz 4-6 6-2 6-4, and eighth seed Felix Auger-Aliassime knocked out Francisco Cerundolo 7-5 6-4.

Third seed Jessica Pegula rallied back from a set down for the second straight match to advance into the final 16 with a 3-6 6-4 7-5 victory over 26th seed Anastasia Potapova.

Potapova won the first set in 39 minutes, claiming the only break of the frame in the sixth game, but Pegula responded by breaking immediately in the second.

Despite squaring the match up, the American trailed 3-1 in the third set, only to fight back again and triumph in two hours and 17 minutes.

Pegula will face 15th seed Petra Kvitova after she won a seesawing three-set contest over 24th seed Jelena Ostapenko, 0-6 6-0 6-4.

Ostapenko won the first six games, before Kvitova won the next 10, only for the Latvian to hit back and claim the next four, squaring up the deciding set at 4-4. But two-time Wimbledon champion Kvitova held her nerve and won the final two games for victory.

World number two Aryna Sabalenka progressed to the final 16 via walkover after her third-round opponent Lesia Tsurenko withdrew.

The 2023 Australian Open champion will take on 2021 French Open winner Barbora Krejcikova after she toppled Wang Xin 6-2 6-7 (1-7) 6-2.
