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.

Top seed and reigning champion Carlos Alcaraz dished out a bagel as he continued his outstanding form with a straight-sets victory over Dusan Lajovic to ease into the Miami Open fourth round on Sunday.

Alcaraz, who triumphed at last week's Indian Wells Open, beat the 76th-ranked Serbian 6-0 7-6 (7-5) in one hour and 32 minutes.

The 19-year-old Spaniard hit 26 winners compared to Lajovic's eight, while Alcaraz also sent down three aces on a 75 per cent first serve percentage.

Alcaraz won the first frame to love in 32 minutes, registering his fourth career bagel at ATP Masters 1000 level, equaling the most by a teenager alongside Rafael Nadal.

The world number one will face 2023 Australian Open semi-finalist Tommy Paul in the fourth round after the American got past 20th seed Alejandro Davidovich Fokina 6-3 7-5.

Third seed and 2022 Miami Open finalist Casper Ruud blew a first-set lead to lose 3-6 6-4 6-4 to Botic Van De Zandschulp.

The Dutchman improved his head-to-head record against Ruud to 3-1 with his first-ever top five win, with the Norwegian left to lament converting only two of 15 break points.

Ninth seed Taylor Fritz progressed into the fourth round with a 6-4 6-4 win over Denis Shapovalov, improving his head-to-head record against the Canadian to 4-5. Fritz committed only eight unforced errors and did not face one break point.

Jannik Sinner maintained his excellent hard-court form with his 18th win this season on the surface, as he defeated Grigor Dimitrov 6-3 6-4 in one hour and 28 minutes. The Italian 10th seed will be Andrey Rublev in the next round.

Sixth seed Rublev needed less than an hour to get past Miomir Kecmanovic 6-1 6-2, while compatriot Daniil Medvedev advanced via a walkover against Alex Molcan due to a right hip injury.

Seventh seed Holger Rune cruised past Diego Schwartzman 6-4 6-2, while Finland's Emil Ruusuvuori got past Taro Daniel 6-3 7-6 (7-3).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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.

Rafael Nadal dropped out of the world's top 10 men's tennis rankings on Monday, the first time he has not been a presence there since his arrival on April 25, 2005.

After struggling with a hip injury since the Australian Open, Nadal has been unable to play much in the early months of 2023, causing his ranking to drop to 13th.

The 22-time grand slam winner has been an ever-present among the elite of the men's game for the best part of two decades.

Having spent half of his life as a top-10 player, Nadal will be determined to get back there once his injury has healed and prove there is still plenty of life in him yet, though may also be a tad sad to realise that new world number one and compatriot Carlos Alcaraz wasn't even two years old in April 2005.

In the interest of nostalgia, Stats Perform has taken a gander back at how the world looked then, and what has changed since.

The Special One makes his mark

Jose Mourinho made quite the impact when he became Chelsea manager at the start of the 2004-05 season, guiding the then Roman Abramovich-owned Blues to their first Premier League crown, and first English top-flight title since 1954-55.

After coining his own moniker of the "Special One" at his first press conference, Mourinho set about living up to it, also adding the EFL Cup in his first season at Stamford Bridge.

Two days after Nadal had entered the top 10 though, Chelsea hosted Liverpool in the first leg of their Champions League semi-final, drawing 0-0 at home, before losing 1-0 in the return leg at Anfield to suffer elimination at the hands of their Premier League rivals.

Mourinho did not take kindly to Luis Garcia's goal being awarded, with goal-line technology not available back then, something the now 60-year-old brought up again as recently as last week.

The Portuguese coach went on to have a storied career that is still going, having won the inaugural Europa Conference League with Roma last season.

He remains as outspoken as ever though, aiming a dig at Roma's rivals Lazio after their elimination from Europe ahead of the Rome derby on Sunday, which Lazio won 1-0 before Biancocelesti defender Alessio Romagnoli revealed: "We were already very energised before this match, his quotes hyped us up even more."

Tennant's Who-per

It was also a different time in television, pre-dating the streaming services so many rely on today, not least tennis players on the road, such as Nadal.

David Tennant was announced as the 10th doctor in Doctor Who, while the first UK series of The Apprentice came to a conclusion and adult-themed animated series Family Guy returned due to popular demand after initially being cancelled following its third season.

Nearly 18 years later, Tennant has reprised his role in Doctor Who, The Apprentice is airing its 17th series in the UK and Family Guy is airing its 21st season in the United States.

The more things change, the more they stay the same... but you can at least now stream all three shows on demand.

Charles and Camilla get married

In April 2005, Prince Charles and Camilla Parker-Bowles tied the knot, getting married at a civil ceremony at Windsor Guildhall.

It is fair to say quite a bit has happened in the British royal family since then, with Princes William and Harry both getting married to fairly different receptions.

With the death of Her Majesty Queen Elizabeth II in September at the age of 96, King Charles III took the throne, and will have his coronation on May 6.

After Alcaraz became the youngest player to end the year as world number one in December, King Charles III will officially become the oldest person to accede to the British throne.

When Nokia ruled the world

If there is one area that has advanced almost immeasurably in the last 18 years, it is phone technology.

In 2005, it was still around two years before the dawn of the smartphone. Statistically, it is likely that even stars like Nadal had to make do with a Nokia 1110, the best-selling phone of the year.

Flip-phones were also becoming popular, with the Motorola RAZR V3 and Samsung Z500 among them, and both companies have revived the design in recent times, with the Samsung Galaxy Z Flip 4 one of the biggest selling phones of today.

Who knows, perhaps Nadal's superfast reflexes and anticipation came from logging hours and hours of practice playing Snake.

Let's see Alcaraz do that.

Rafael Nadal has dropped out of the world's top 10 men's tennis rankings for the first time in almost 18 years.

Nadal has been in the top 10 ever since April 2005, but on Monday fell to 13th in the ATP rankings after injury forced him to miss Indian Wells.

The 36-year-old's run came to an end on the same day that teenage compatriot Carlos Alcaraz reclaimed his number one spot from Novak Djokovic after beating Daniil Medvedev in Sunday's Indian Wells final.

Nadal is yet to recover from the hip injury that has hampered him since his Australian Open exit to Mackenzie McDonald in January.

Though the 22-time grand slam winner could return to the top 10 once he is back in action, it will not be in the next month as he has also withdrawn from the Miami Masters.

The latest ATP rankings saw Djokovic drop to second place, while Medvedev moved from sixth to fifth, Felix Auger-Aliassime leapt from 10th to sixth, Hubert Hurkacz nudged into the top 10 as he moved up two places to ninth, while Taylor Fritz dropped from fifth to 10th.

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.

Tennis will never see a "big three" with the quality of Rafael Nadal, Novak Djokovic and Roger Federer again, believes Juan Martin del Potro.

The trio, who have combined for a total of 64 men's singles grand slam titles across a near-two-decade-long period of dominance, have come to define the sport's modern era.

Federer retired last year and while Nadal and Djokovic continue, both are well into the twilight of their careers, despite astonished continued success.

Del Potro, the 2009 US Open winner, also retired in 2022, and he thinks the trio's dominance is unlikely to be replicated going forward, even though he sees Carlos Alcaraz, Jannik Sinner and Holger Rune as three players who could possibly go on to enjoy great success.

"The only thing I lacked was being number one [in the ATP Rankings]," he said. "It was always a dream, and I always worked for it. I never made it because there was either Federer, or Nadal, or Djokovic.

"When I look at the rankings and the years of my career and who was fighting to be number one I see that it was beautiful that these were the ones who didn't let me make it, this dream."

"One day, the big three will end. We have Carlos Alcaraz, Jannik Sinner [and] Holger Rune, other young people who will mark the circuit.

"But for me, [for] many years, [it was] the big three. There will not be anything similar."

Del Potro reached a career high-mark of third in the ATP Rankings in 2018, with Andy Murray the only man other than Nadal, Federer or Djokovic to top the charts between 2005 and 2021.

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.
