Rafael Nadal has cast doubt on a possible return at next month's Monte Carlo Masters after revealing he is still unsure when he will be ready to make his comeback.

The 22-time grand slam champion has been struggling with a left hip issue that contributed to his second-round exit at the Australian Open in January.

Nadal pulled out of hard-court contests at the Indian Wells Open and Miami Open as he continued to recover from the problem.

Speaking two weeks ago, Monte Carlo Masters director David Massey said Nadal was the first player to register for this year's Masters 1000 event, which begins on April 8.

The tournament's official Twitter account more recently suggested Nadal will "definitely" take part.

However, Nadal – who has slipped out of the world's top 10 men's tennis rankings for the first time in almost 18 years – denied that is the case.

"I don't know who gets this information," he is quoted as saying by Spanish publication Marca.

"Obviously if it were true, I would confirm it, but unfortunately I can't. I'm following my course and I don't know when I'll play again, that's the truth.

"I'm in a phase of increasing work. If I knew when I was going to return, I would say so, but I don't know.

"I can't confirm that I will play in Monte Carlo. Things are seen day by day. I prefer to say things when I really know them."

The Monte Carlo Masters kicks off the clay-court season ahead of events in Madrid and Rome, with the French Open – Nadal's favourite event – now just two months away.

Nadal has won the Monte Carlo Masters a record 11 times, though his most recent triumph came in 2018 with victory over Kei Nishikori in the final. 

Three of the top seeds in the Miami Open field were eliminated on Monday as Felix Auger-Aliassime, Hubert Hurkacz and Frances Tiafoe were all sent packing.

Fifth seed Auger-Aliassime was taken out 6-2 7-5 in one of the biggest wins of Francisco Cerundolo's career, with the Argentine avenging recent losses to the Canadian at both the Australian Open and the Indian Wells Open.

Adrian Mannarino's 7-6 (7-5) 7-6 (7-0) victory over eighth seed Hurkacz was arguably an even bigger upset, as it snapped his streak of nine consecutive losses against top-10 opponents at Masters 1000 events.

The 34-year-old Frenchman absorbed 20 aces from Hurkacz and still came out on top, limiting his own unforced errors to 13 for the match.

A third upset of the day saw unseeded Italian Lorenzo Sonego play a near faultless match to eliminate 12th seed Tiafoe, finishing the contest with 22 winners and only two unforced errors, while not facing a single break point in the brief 68-minute battle.

There was no drama for Daniil Medvedev as the fourth seed received a walkover against Alex Molcan, and he will face France's Quentin Halys in the fourth round after his 7-6 (7-2) 6-3 triumph over Mackenzie McDonald.

Two seed Stefanos Tsitsipas almost joined the long list of seeded victims, but he prevailed 6-3 4-6 6-4 against Christian Garin in the day's only three-setter.

The Greek star will meet Russian 14th seed Karen Khachanov in the fourth round after his comfortable 6-2 6-4 result over Jiri Lehecka, while unseeded American Christopher Eubanks finished the day's play with a 6-3 7-6 (9-7) defeat of Gregoire Barrere.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

"I have no regrets," Djokovic told CNN.

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

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

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

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

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

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

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

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

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

Jack Draper has pulled out of the Miami Open due to an abdominal injury that forced him to retire from his match against Carlos Alcaraz at Indian Wells.

The Briton suffered a tear to his oblique muscle during his fourth round encounter with the Spaniard, forcing him to bring the match to a premature end in the second set.

While Alcaraz went on to win the tournament and reclaim his position as world number one, Draper is now set for a spell on the sidelines.

The 21-year-old has decided to withdraw from Miami, in order to focus on making a full recovery rather than risk aggravating the issue.

The world number 43 struggled for fitness during the 2021 season, but played 22 events last year and reached the quarter-finals of the Canadian Open.

Alcaraz won his first ATP Masters 1000 title in Miami last year by beating Casper Ruud in the final. 

After being awarded a bye into the second round, he will face either Facundo Bagnis or a qualifier and could take on Andy Murray in round three as he eyes a Sunshine Double.

New world number one Carlos Alcaraz says he played "perfect" in Sunday's final demolition of Daniil Medvedev to cap a "perfect tournament" as he lifted the Indian Wells title for the first time.

Despite Medvedev coming into Sunday's decider on a 19-match winning streak, Alcaraz dominated 6-3 6-2 to win in 72 minutes.

Alcaraz's Indian Wells triumph was his third ATP Masters 1000 crown from three finals, not dropping a set in any of those deciders.

The 19-year-old Spaniard went through the Indian Wells Open without dropping a set and reflected that it was a "perfect" fortnight for him.

"It feels amazing to lift the trophy here [and] to recover the number one," Alcaraz told reporters, having reclaimed the top rank from Novak Djokovic due to his victory.

"It has been the perfect tournament. It was a goal for me, this tournament that I really wanted to win. For me, it's amazing."

The lopsided nature of Alcaraz's victory over Medvedev in the final caught many by surprise, hitting 19-4 winners against the in-form fifth seed.

"Honestly I didn’t expect that," Alcaraz said. "I expected a tough match but I played perfect. I said before against Daniil you have to play your best and tactically at your best level as well. I did perfect today. That's why it looks easy but it wasn’t."

Alcaraz added he was delighted to reclaim the number one rank which he had lost after Djokovic won the 2023 Australian Open which he missed due to injury.

Djokovic was unable to participate at Indian Wells due to being unvaccinated for COVID-19, with the pair actually not facing off at any events this year.

Alcaraz returned from abdominal and hamstring injuries last month at the Argentina Open and Rio Open before competing at Indian Wells, while Djokovic was in action at the Dubai Tennis Championships. The next opportunity for the pair to face off as at April's Monte Carlo Masters.

"Novak is one of the best players in the world," Alcaraz said. "That's obvious. I always say, if you want to be the best, you have to beat the best. I really wanted to play against Novak again. We miss him on tour and hopefully to have him back very, very soon."

Alcaraz added: "It feels great to be back on the number one. Of course, every player on the ATP wants to be the number one. For me, it's a dream come true again. Obviously being in front of such great players like Novak, the top player, it's an amazing feeling."

Despite Djokovic being unable to compete at Indian Wells, Medvedev said he felt Alcaraz's return to the top rank was a true number one.

"One hundred per cent," Medvedev said. "It's unfortunate Novak can't play all the tournaments. If you get injured, Rafa is injured for some time, we cannot say if Rafa isn’t injured he would be number one, because we cannot know. Same about Novak.

"For sure if he was able to play last year and this year all the tournaments there is a possibility that the rankings would be different but Carlos is deservedly number one, he won more points than everybody else in the last 52 weeks and he was also year-end number one last year."

New world number one Carlos Alcaraz says he played "perfect" in Sunday's final demolition of Daniil Medvedev to cap a "perfect tournament" as he lifted the Indian Wells title for the first time.

Despite Medvedev coming into Sunday's decider on a 19-match winning streak, Alcaraz dominated 6-3 6-2 to win in 72 minutes.

"For sure if he was able to play last year and this year all the tournaments there is a possibility that the rankings would be different but Carlos is deservedly number one, he won more points than everybody else in the last 52 weeks and he was also year-end number one last year."

Daniil Medvedev joked about a love-hate relationship with the Indian Wells Open court and his failure to create an entertaining final after his heavy defeat to Carlos Alcaraz.

Medvedev's winning streak was halted at 19 matches by the sensational Alcaraz, who claimed his third Masters 1000 title in style on Sunday.

Alcaraz won 6-3 6-2 in just 72 minutes to return to the summit of the ATP rankings, with Novak Djokovic having been unable to feature in the United States due to his COVID-19 vaccination status.

Medvedev had won three titles in a row – at the Rotterdam Open, Qatar Open and Dubai Tennis Championships, where he beat Djokovic – ahead of competing at Indian Wells, yet proved no match for the imperious Alcaraz, who he had beaten in their only previous meeting, at Wimbledon in 2021.

The Russian had to overcome several hurdles to reach the final, having rolled his ankle in his fourth-round win over Alexander Zverev while he also hurt his thumb in a quarter-final defeat of Alejandro Davidovich Fokina.

Yet despite the trials and tribulations, and his humbling loss in the final, Medvedev was in good spirits.

"I had a pretty toxic relationship here with the courts, a love-hate relationship," Medvedev chuckled. "So I'd like to thank the court!

"I only played on this court. I gave it a hard time so it gave me a hard time also. Rolled the ankle, the thumb... but it gave me the chance to finish the tournament.

"Thanks a lot to this court, I'll definitely be back.

"I really love this tournament, I'll be happy to come back many more years to come and hopefully I can start to love this court and Indian Wells together."

Addressing the crowd, Medvedev quipped: "Sorry I didn't make this final entertaining. I tried, I don't like to lose, but today was unfortunately pretty easy. I hope you still enjoyed it."

Alcaraz is one of only three players to hold a 100 per cent record in multiple ATP Masters 1000 finals, having now won in the finals of the Miami Open, Indian Wells Open and Madrid Open without dropping a set.

"I'd like to congratulate Carlos," said Medvedev. "You already have amazing achievements in your career and I'm sure many more to come.

"Today's one more of them, winning Indian Wells. I also dream of it – maybe next time you'll give me the chance!

"Congrats to you and your team. You're probably the most respectful player on Tour, you probably say hi to 300 people a day. I've rarely seen it!"

Alcaraz returned the plaudits, telling Medvedev he serves as an inspiration to be "better on the court and off the court".

"It has been a really amazing run here, such an amazing experience," the 19-year-old added.

When asked if he had played a near perfect match, Alcaraz told Amazon Prime: "Yes, probably. I played really, really well.

"I made no tactical mistakes, which is really important against Daniil. I would say I was perfect in that way.

"I'm really happy with the way I played, the trophy and of course to be world number one."

While Alcaraz will return to the top of the world on Monday, compatriot and idol Rafael Nadal is set to drop out of the top 10 for the first time since April 2005.

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.

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.

Two of the Indian Wells Masters' top-three seeds have failed to reach the final 16 after Casper Ruud fell 6-4 7-6 (7-2) at the hands of Cristian Garin on Sunday.

Ruud, the third seed, joined second seed Stefanos Tsitsipas with an early exit after a timid display, with just 17 winners to go with 17 unforced errors against Chile's Garin.

Meanwhile, Garin took his opportunity against the world number four with both hands, rattling off 39 winners with 24 unforced errors as he made the decision to take the match on and not die wondering.

Garin, who already defeated 29th seed Yoshihito Nishioka in the second round, will meet his third seeded opponent in a row in the quarter-final when he takes on Spain's 23rd seed Alejandro Davidovich Fokina.

Davidovich Fokina eliminated 13th seed Karen Khachanov 6-3 1-6 6-4, but it was still a strong day for the Russians as top hopefuls Daniil Medvedev and Andrey Rublev advanced.

Medvedev, the fifth seed, was tested in his 6-2 3-6 6-1 victory over Belarus' Ilya Ivashka, while sixth seed Rublev saw off France's Ugo Humbert 7-5 6-3 without much issue.

Waiting for Rublev in the quarter-final is Briton Cameron Norrie after his 6-7 (5-7) 7-5 6-2 battle against Taro Daniel, while Alexander Zverev beat Emil Ruusuvuori 7-5 1-6 7-5 to book a tantalising clash with Medvedev.

In a poor day for the Australians, Jason Kubler went down 6-3 6-2 against 14th seed Frances Tiafoe, and Jordan Thompson could not follow up his incredible upset against Tsitsipas, falling 6-3 7-6 (8-6) to Chile's Alejandro Tabilo.
