Daniil Medvedev is on a mission to avoid being remembered as a two-week wonder at world number one as he attempts to claw top spot back from Novak Djokovic.

The US Open champion climbed to the summit of the ATP rankings in late February of this year and had a fortnight there before surrendering the top rung to Djokovic, the long-time incumbent.

Djokovic remains there and has spent a record 371 weeks at number one across his career, while Roger Federer had 310 weeks on top and Rafael Nadal 209 weeks.

Their dominance has been at the extreme end of the sporting spectrum, and Medvedev will probably never get close to matching any of their totals, but there is a strong chance he will jump back to number one sooner rather than later.

Medvedev revealed on Saturday he had searched on the internet to learn which players had short runs at number one comparable to his own, such is his fascination.

He is closely tracking Djokovic in the current world rankings, and should he reach the French Open final next weekend he will overtake the 35-year-old Serbian – even if Djokovic successfully defends his Roland Garros title.

Then the decision by the ATP to strip Wimbledon of ranking points means Djokovic will lose 2,000 points after that tournament, having been champion last year, while Medvedev has only a handful to hand back. He is banned from Wimbledon, as all Russians are, and is unhappy to be missing out, but he stands to benefit on the rankings list.

"I for sure want to be there more than two weeks. I want to try to do it," Medvedev said. "We don't know how, this Wimbledon thing, but I want to try to make the best results possible."

Medvedev recalled being told by Tennis Channel how he could return to number one in Paris, saying that was "great to know".

"That's great motivation," Medvedev said. "It's not something that pressures me, because I'm really happy I managed to do it.

"I remember at Indian Wells I lost, I didn't like my match against Gael [Monfils], and that's when I knew I was going to lose the number one spot.

"I was like, well, just two weeks. I went on the internet and looked just like this on Google, who were the shortest number one players in the world, and the first I saw was Pat Rafter being there for one week, and he's an absolute legend, and Carlos Moya was somewhere there. Two weeks.

"If somebody would ask me, how long were Rafter and Moya number one, I'd say, I don't know, six months, one year."

After a 6-2 6-4 6-2 win over Djokovic's compatriot Miomir Kecmanovic, which set up a last-16 clash with Maric Cilic, the 26-year-old Medvedev spoke of his pride at having briefly lorded it over his tour rivals.

"It's something nobody can take away from me," he said. "Not that many players could take it while they play tennis. It's a great motivation to try to come back there."

Daniil Medvedev is outgrowing his phobia of spiders while learning how to handle his tennis fears as he targets a long run at the French Open.

The popular Russian made pain-free progress past Serbian Laslo Djere on Thursday, winning 6-3 6-4 6-3 to set up a third-round clash with Miomir Kecmanovic.

He spoke afterwards about the difficulties of staying informed about off-court matters, particularly whether there could be twists to come surrounding Wimbledon's ban of Russian and Belarusian players this year.

Medvedev is keen to keep his focus on what happens on court, and while tennis may stoke up emotions, such as when the world number two was cut up by his defeat to Rafael Nadal in the Australian Open final, he is determined to develop mechanisms to deal with trauma.

"I think fear is one of the toughest emotions in people's lives, because a lot of mistakes we do in life are because we are scared of something," Medvedev said.

"That's how I think. And yeah, I'm a little bit scared of spiders, but I need to say I was much more scared when I was 10 or 12.

"When you grow up you need to sometimes face your fears. I never saw a tarantula, so I think I'm going to be scared if I see one. I'm not scared any more of small spiders.

"Fear is actually what we can feel every day in tennis. You're scared to lose. Sometimes you are scared what people are going to think about you.

"For example, I was number one in the world for two weeks, if I'm not mistaken. I'm not scared if people are going to say, 'Well, yeah, it doesn't matter, you were only two weeks'.

"But you can be scared of this. I think in every sport, especially the higher you get, the more you can have this situation.

"I try to work hard on not being scared of anything and just learning, even if I do mistakes, not being scared to repeat them but try not to repeat them.

"To be honest, I'm not scared of much right now in my life."

Daniil Medvedev has given the ATP credit for reaching a "logical" decision to strip Wimbledon of ranking points – and the Russian stands to benefit by going back to number one in the world.

There would need to be a remarkable turn of events for Novak Djokovic to retain top spot at the end of the short grass-court season, given he has a mountain of points to defend over the next two months and will lose the 2,000 that he earned by winning Wimbledon last year.

That is the standard total awarded to a grand slam singles champion, with Medvedev earning the same number for his US Open triumph in September.

The decision by the ATP, which runs the men's professional tour, to effectively punish Wimbledon for its decision to ban Russian and Belarusian players, means the absent Medvedev at least stands to benefit in the rankings given he only has 180 points to lose from the London grand slam.

Djokovic carried a lead of only 680 points over Medvedev into the French Open, where the Serbian is again defending 2,000 points after beating Stefanos Tsitsipas in last year's final. Medvedev was a quarter-finalist in Paris last year, collecting 360 points.

Medvedev may yet go top before Wimbledon, but there is a strong chance Djokovic begins his campaign at the All England Club knowing he will be powerless to prevent his number one status sliding away.

"About the ATP decision, it is not easy to comment, but when I read the FAQ of the ATP, why they made this decision, because they are explaining themselves, they are not just saying, 'Okay, we decided that', I found it very logical what they say at least," Medvedev said.

"This is what I didn't find in Wimbledon explanations. I'm not saying which decision is right, but at least so far in explaining their decisions, I found ATP just more logical."

The ATP said its decision, which has been unpopular with many, was reached "purely on the basis of maintaining a level playing field for our players across the season".

Medvedev began his French Open campaign on Tuesday with a clinical 6-2 6-2 6-2 win against Argentinian Facundo Bagnis, showing no ill effects of recent hernia surgery.

Smiling, Medvedev said it was "very strange" that he might become the world's top-ranked men's player while exiled from Wimbledon.

"But I'd be really happy to play Wimbledon. I love Wimbledon," said the 26-year-old, who plans to compete at grass-court events in Germany and the Netherlands in June.

"I love playing on grass. I will play on grass after Roland Garros. But if I cannot, I'm just going to prepare for the next tournaments and follow what's happening there.

"There are no points, I become number one, well, great for me. If there are points, I cannot become number one, I'm going to be gutted. It is what it is. I cannot change some decisions, both about ATP and Wimbledon."

Novak Djokovic returns to the grand slam arena, Carlos Alcaraz is threatening to follow in the footsteps of Rafael Nadal, and Iga Swiatek is suddenly unstoppable.

The French Open is rich in promise as the Roland Garros clay courts are swept in anticipation of the greats of tennis stepping out to begin their campaigns.

It has been the women's draw that has looked the most wide open in recent seasons, yet this year it is hard to look beyond Swiatek; however, the men's title battle promises to provide a sensational battle.

Here, Stats Perform assesses the contenders for the two main trophies: the Coupe des Mousquetaires and the Coupe Suzanne Lenglen.

KID INTERRUPTS G.O.A.T. RACE

Nadal took full advantage of Djokovic and Roger Federer being absent from the Australian Open, carrying off his 21st grand slam title to go top of the men's all-time list, one ahead of those two great rivals.

Federer is again missing, rehabbing after knee surgery, and the likelihood is he has played his final major already, but Djokovic is emphatically back. His confidence is surging once more, having taken a knock amid the drama of his deportation from Australia in January and being frozen out of the Indian Wells and Miami events due to the United States' COVID-19 rules.

A semi-final run in Madrid, where he lost a three-set monster to Alcaraz, was followed by Djokovic carrying off the Rome title for a sixth time when he saw off Stefanos Tsitsipas in the final.

Djokovic turns 35 on Sunday, as main-draw action gets under way in Paris, but he is the defending champion and firmly believes he can succeed again.

Assessing his prospects for Paris, Djokovic said after his Rome triumph: "With rankings and the way I've been playing in the last few weeks, I would rate myself as one of the favourites. I don't obviously spend too much time thinking who's going to win it or who might have the best chance. I always think about myself.

"I go there with the highest ambitions. I really like my chances. Best-of-five, you play every second day. It's a grand slam. It's different. Really, the grand slams are played different. You have to approach it differently. But the way I've been feeling on the court and off the court in the last few weeks, I really think I can go far."

The chief threat to Djokovic could come not from 'King of Clay' Nadal, but from the 13-time champion's fellow Spaniard, 19-year-old Alcaraz.

Bidding to become the first teenage winner of the men's title since Nadal, also 19, triumphed for the first time in 2005, Alcaraz arrives in Paris with four titles already secured this year, including three on clay in Rio, Barcelona and Madrid. The other title came on hardcourt at the Masters 1000 event in Miami, and Alcaraz has rocketed from 32nd at the start of the year to number six in the world rankings.

Many expect his grand slam haul to reach double digits, just like the Big Three he has grown up watching and learning from. The first slam must come somewhere, and it might well come in Paris in a fortnight's time.

Don't discount Nadal, but his form has been a shade unconvincing since coming back from a rib injury, while Tsitsipas looks the next most likely after winning on clay in Monte Carlo and finishing runner-up to Djokovic in Rome. The Greek has unfinished business in Paris, after the heartache of losing last year's final from two sets up.

IGA TO PLEASE? POLE GOES FROM SHOCK WINNER TO FIRM FAVOURITE

The first thing to point out is that the French Open women's singles title has been won by eight different players in the last eight years.

Iga Swiatek was a surprise champion in 2020, at the tournament that was delayed until the Paris autumn due to the pandemic. She was ousted by Maria Sakkari in the quarter-finals last year but returns on a roll, having won an incredible five consecutive tournaments.

The 20-year-old has won 38 of the last 39 sets she has contested, the odd one out going against her on a tie-break, and her winning streak has reached 28 matches. Since Ash Barty retired, nobody has been able to lay much of a glove on Swiatek.

If she wins the French Open, that run will reach 35 matches, equalling the longest run in the 2000s, previously achieved by Venus Williams during a glory run that saw her win events including Wimbledon, the Olympic Games and US Open in the year 2000.

Tunisia's Ons Jabeur has been spoken of as a possible challenger to Swiatek, but she was swatted away 6-2 6-2 by the youngster in the Rome final last weekend.

So who challenges the favourite? Even those who have been there and done that struggle to look beyond Swiatek. According to Martina Navratilova: "You can’t be any hotter than she is right now."

Navratilova told the WTA website: "She looks pretty unbeatable on any surface, particularly the clay now."

The last player to beat Swiatek was Jelena Ostapenko, in Dubai. Ostapenko, a surprise 2017 French Open champion, had a sizzling spell of form in February but has gone off the boil since. It might take someone of her hard-hitting nature to knock Swiatek out of her stride, though, so if Ostapenko can navigate the early rounds she becomes a real contender. The Latvian's career record against Swiatek? An impressive 3-0.

Who else? Simona Halep's coaching tie-up with Patrick Mouratoglou – Serena Williams' former coach of long-standing – has raised eyebrows and now it might be time for it to raise her results level too. Halep has won in Paris before, in 2018, so don't count her out.

Aryna Sabalenka, Sakkari, Paula Badosa. Such players come into the mix if Swiatek slips up, but there has been scant sign of that happening.

Daniil Medvedev remains dismayed by the prospect of missing Wimbledon but has ruled out taking the All England Club to court in a bid to overturn the ban on Russian players.

The US Open champion is in Paris for the French Open, which is allowing players from Russia and Belarus to compete.

Stars from those countries have been denied entry to Wimbledon next month, however, due to the Russian-led invasion of Ukraine.

They will not be allowed to play any events in England, the Lawn Tennis Association said, but Medvedev is determined to play a grass-court season and has signed up for tournaments in Netherlands and Germany already, while considering another in Spain.

The 26-year-old from Moscow has expressed hope that there could yet be a way for him into the Wimbledon draw, and stuck by that position on Friday.

"I'm not in the ATP taking the decisions, I'm not in Wimbledon taking the decisions. Maybe it's government pushing them, maybe it's their decision. There a lot of mistakes behind this," Medvedev told a news conference at Roland Garros.

"So if I can play I'm going to be happy to play. I love Wimbledon as a tournament. I honestly tend to think I like playing on grass, though I didn't have amazing results so far, but I managed to win one tournament. But if I cannot play, I'm going to try to play next year's and try to play good there."

Asked whether he would consider recourse to the Court of Arbitration for Sport, Medvedev said: "Personally, I didn't think about this."

He suspects there might be a case to be made, but added: "I'm not going to go to court for this one."

Court action might not be considered a good look, given the circumstances, so Medvedev looks like having to settle for playing the satellite ATP Tour events around the grass-court showpiece.

"Usually I like playing grass. I want to make some good results," he said. "Halle is a really strong tournament and if you manage to win it, it's a great result and gives you a lot of confidence no matter for the next tournaments if it's grand slams or not, or if it's Masters 1000.

"So I'm planning to play three grass-court events, which is 's-Hertogenbosch, Halle, and I'm thinking to go to Mallorca."

Medvedev, who has spent time sidelined by hernia trouble recently, will face Facundo Bagnis in the first round in Paris.

Novak Djokovic, Rafael Nadal and Carlos Alcaraz are all on the same half of the draw at the French Open, while women's world number one Iga Swiatek will face a qualifier in the first round at Roland Garros.

Djokovic, who will make his Grand Slam return having missed the Australian Open, opens in Paris against Yoshihito Nishioka, while record 21-time grand slam winner Nadal meets Australia's Jordan Thompson.

The veteran pair of Djokovic and Nadal could challenge each other in the quarter-finals in the top half of the draw, where Alcaraz could come across world number three Alexander Zverev.

Alcaraz faces a qualifier in the first round and has won 16 of his last 17 matches, with the one blemish on his remarkable run coming against Sebastian Korda, who the Spaniard could meet in the third round.

Daniil Medvedev will have to get past Argentine Facundo Bagnis in the first round, while Lorenzo Musetti stands in the way of last year's runner-up Stefanos Tsitsipas.

Medvedev and Tsitsipas are joined in the wide-open bottom half of the draw by Casper Ruud and Andrey Rublev, who meet home favourite Jo-Wilfried Tsonga and South Korea's Soonwoo Kwon respectively.

In the women's draw, 2020 champion Swiatek comes in as favourite and will look to continue her 28-match winning streak when she faces a qualifier in the first round, as does US Open winner Emma Raducanu.

The Brit will then take on Aliaksandra Sasnovich or Wang Xinyu before a potential last-16 meeting with Ons Jabeur, who first has to get past Poland's Magda Linette.

Meanwhile, Karolina Pliskova – who has a first-round clash with France's Tessah Andrianjafitrimo – could set up a quarter-final meeting with Swiatek, but the Pole may have to get past Simona Halep in the fourth round first.

Defending champion Barbora Krejcikova starts against Diane Parry, while Naomi Osaka was drawn against the in-form Amanda Anisimova, who beat the Japanese in the third round of the Australian Open.

Daniil Medvedev was defeated on his ATP Tour return at the Geneva Open by a sparkling Richard Gasquet, a blow to the Russian ahead of the French Open

World number two Medvedev was making his first appearance since March after undergoing a hernia operation and fell to a 6-2 7-6 (7-5) defeat.

The Russian's rustiness was clear in the last-16 tussle as he racked up seven double faults and struggled to make inroads on Gasquet's second serve, with the Frenchman winning 61 per cent of points behind it.

It was the first time Gasquet overcame an opponent ranked in the top two since beating Roger Federer at the 2005 Monte Carlo Masters.

Next up for Gasquet will be Kamil Majchrzak, who beat Marco Cecchinato 6-2 6-3.

At the last-32 stage, Fabio Fognini went down 6-4 6-3 to Thanasi Kokkinakis and Albert Ramos-Vinolas succumbed to a 7-6 (7-5) 6-4 loss against Christopher O'Connell.

Johan Nikles, Nikoloz Basilashvili and Joao Sousa also advanced to the second round.

Top seed Cameron Norrie cruised into the quarter-finals of the Lyon Open by beating Francisco Cerundolo 6-4 6-4.

The Briton will face another Argentinian next in the form of Sebastian Baez, who came from a set down to beat Oscar Otte 5-7 6-4 6-2. 

Alex De Minaur also had to rally for a 1-6 6-3 6-2 win against Ugo Humbert, with Yosuke Watanuki awaiting in the last eight after the world number 263 beat Soonwoo Kwon 6-3 6-4.

Daniil Medvedev remains hopeful he can feature at Wimbledon despite Russian and Belarusian players being banned from the tournament due to the conflict in Ukraine.

The All England Club, along with the Lawn Tennis Association, confirmed in April that Russian and Belarusian players would not be permitted to play this year, due to Russia's ongoing invasion of Ukraine.

That means unless the ATP and WTA can convince tournament organisers to rethink, men's world number two and reigning US Open champion Medvedev will not compete at Wimbledon.

The decision has split opinion in tennis, with the likes of Novak Djokovic, Rafael Nadal and Andrey Rublev questioning the ruling, while Andy Murray expressed his backing.

However, Medvedev has not given up hope that Wimbledon may opt for a late change of heart and allow him to play.

"I don't know if this decision is 100 per cent and it's over [for me]," the Russian said.

"If I can play, I'm going to be happy to play in Wimbledon. I love this tournament. If I cannot play – well, I'm going to try to play other tournaments and prepare well for next year if I have the chance to play."

Questions remain as to a potential backlash should Wimbledon exclude the two countries' players from appearing, with reports suggesting the ATP and WTA may remove ranking points from the tournament.

"I tried to follow what's happening because I don't have any decisions to make. It's right now about Wimbledon itself, the ATP, maybe the British government is involved," Medvedev added.

"It's a tricky situation and like every situation in life, you ask 100 players, everybody's going to give a different opinion.

"[When] you show a tennis ball to 100 people, I'm sure some of them are going to say it's green and not yellow. I think it's yellow. [But] if somebody tells me it's green, I'm not going to get in conflict with this person."

Medvedev returns to action this week at the Geneva Open, where he faces Richard Gasquet or Australian John Millman in his opening match after recovering from a hernia injury that kept him out for six weeks.

Daniil Medvedev headlines the list of Russian and Belarusian players who will be banned from competing at Wimbledon this year.

In the wake of Russia's invasion of Ukraine, which was facilitated by Belarus, the four grand slams and the ATP and WTA Tours initially confirmed Russian and Belarusian players would be able to continue playing, albeit under neutral flags.

However, the All England Club has now decided athletes from the two nations will be unable to feature at the season's third grand slam.

That means reigning US Open champion Medvedev, ranked second in the world by the ATP behind Novak Djokovic, will not be involved.

With Medvedev a doubt for the French Open having undergone hernia surgery, he could miss two of this year's majors. He has never had much success at Wimbledon, with his best run ending in the fourth round in 2021.

WTA world number four Aryna Sabalenka, who hails from Belarus, is another big name to miss out, along with Russian ATP world number eight Andrey Rublev, who has won two titles so far in 2022.

Russian women's number one Anastasia Pavlyuchenkova, compatriot and 2018 Wimbledon quarter-finalist Daria Kasatkina and Belarusian two-time All England Club semi-finalist Victoria Azarenka will all also be absent.

"We share in the universal condemnation of Russia's illegal actions and have carefully considered the situation in the context of our duties to the players, to our community and to the broader UK public as a British sporting institution," a statement on the official Wimbledon website read.

"We have also taken into account guidance set out by the UK Government specifically in relation to sporting bodies and events.

"In the circumstances of such unjustified and unprecedented military aggression, it would be unacceptable for the Russian regime to derive any benefits from the involvement of Russian or Belarusian players with The Championships. It is therefore our intention, with deep regret, to decline entries from Russian and Belarusian players to The Championships 2022."

Chairman of the All England Club, Ian Hewitt, said: "We recognise that this is hard on the individuals affected, and it is with sadness that they will suffer for the actions of the leaders of the Russian regime.

"We have very carefully considered the alternative measures that might be taken within the UK Government guidance but, given the high profile environment of The Championships, the importance of not allowing sport to be used to promote the Russian regime and our broader concerns for public and player (including family) safety, we do not believe it is viable to proceed on any other basis at The Championships."

Wimbledon's statement confirmed that the ban would be "reconsidered" should circumstances change by June.

The move comes a month after UK sports minister Nigel Huddleston warned Medvedev and other Russian athletes they might be banned from Wimbledon unless they denounced president Vladimir Putin.

Medvedev and Rublev both called for peace in the immediate aftermath of Russia's attack on Ukraine.

Daniil Medvedev has confirmed he will undergo a procedure to fix a troubling hernia issue, which may keep him out of the French Open.

Medvedev, who enjoyed a short-lived stint as world number one at the start of March before relinquishing the crown back to Novak Djokovic, reached the quarter-finals at Roland Garros last year.

However, the chances of the Russian appearing in Paris now seem slim, given he faces up to two months out of action following the impending operation.

This year's French Open runs from May 22 until June 5.

"Hi everyone," the world number two tweeted on Saturday. "The last months I have been playing with a small hernia.

"Together with my team I have decided to have a small procedure done to fix the problem. I will likely be out for the next 1-2 months and will work hard to be back on court soon. Thanks for all the support."

Medvedev had been hoping to use the clay court swing to reclaim top spot in the ATP rankings.

He could have done so had he reached the semi-finals of the Miami Open last week, yet the 26-year-old lost 7-6 (9-7) 6-3 in the quarters to Hubert Hurkacz.

Medvedev appeared to be struggling in that tie and after the defeat he told reporters: "All the match I was not feeling my best. But, you know, sometimes it happens.

"I don't know the actual reason. Maybe the heat. But I was feeling super, like, dizzy, tired, and there was this long game where I couldn't serve anymore.

"Then in the locker room I was cramping quite much, so physically was not easy. But at the same time, that's part of the game."

Should Medvedev fail to return in time to make the season's second grand slam, the reigning US Open champion will hope to be fully firing by the time Wimbledon comes around in late June.

Daniil Medvedev believes he is in a good spot despite letting slip his chance to claim the world number one ranking at the Miami Masters, losing 6-7 (5-7) 3-6 to Hubert Hurkacz on Thursday.

Medvedev had to deal with dizziness and fatigue during the match, taking a medical timeout against the defending champion in Miami, and was disappointed he was not able to produce his best tennis.

The defeat means the 25-year-old will stay behind Novak Djokovic, who has not played on the ATP Tour since losing to Jiri Vesely back in the quarter-finals in Dubai.

Heading into the clay season, the Russian world number two is buoyant after a 4-2 record across Acapulco and Indian Wells.

"I'm kind of happy about the tournament in Miami in a way of tennis… I managed in Miami to find just a little spark to make it work," Medvedev said post-match.

"Today was not enough, but I'm happy that I saw that I'm able to do it. I'm in the right direction, so it's good."

Hurkacz will face Carlos Alcaraz, who made his second ATP 1000 semi-final after a thrilling 6-7 (5-7) 6-3 7-6 (7-5) victory against Miomir Kecmanovic.

Both Alcaraz and Kecmanovic exhibited extraordinary court coverage in a match-up between two of the more adept returners of serve on the tour, but the 18-year-old Spaniard could simply find a higher gear as points progressed.

Alcaraz played some inspired tennis to break back in the seventh game in the opening set, shifting Kecmanovic around the court to set up a stunning cross-court backhand pass for break point, before stepping in on the second serve to restore parity.

Despite Kecmanovic holding to love in his next two service games, it did not put consequent pressure on his teenage opponent, who forced a tie-break. However, Kecmaovic clawed back from a mini-break to take a riveting opening set.

Hitting 52 winners for the match, the world number 16 pulled out his best tennis of the match in Kecmanovic's opening service game of the second set, coming up with a magnificent lob on the run to set up the break.

Saving break point while serving for the set, he held out to force a deciding third. Coming back from a mini-break in the third set tie-break, Alcaraz ended the match on fitting note, scrambling to the net to slice past Kecmanovic at the end of a frenetic rally.

Daniil Medvedev missed the chance to return to the top of the rankings as he was beaten by Hubert Hurkacz in the quarter-finals of the Miami Open on Thursday.

Medvedev would have become world number one once again if he had defeated Hurkacz, but the defending champion won 7-6 (9-7) 6-3 on Hard Rock Stadium.

Novak Djokovic will remain the top-ranked male player on the planet thanks to Pole Hurkacz, who levelled his head-to-head record with the Russian at 2-2.

Carlos Alcaraz or Miomir Kecmanovic will do battle with eighth seed Hurkacz, who won 74 per cent of points on his first serve and broke Medvedev's serve three times, for a place in the final.

Hurkacz's win over the top seed was his second against a top-two player, with the first also coming against Medvedev at Wimbledon last year.

"I think the return was crucial. I was able to make a lot of returns and get some free points on my serve, because having rallies with Daniil is fun, but they get long,” Hurkacz said on his on-court interview.

"It is good I was able to get some free points. I have spent a lot of time in Florida, so I am used to the humidity. I think the conditions were in my favour today, so I tried to use them."

Emerging Spanish star Carlos Alcaraz continued his rise with a 7-5 6-3 upset of third seed Stefanos Tsitsipas to reach the Miami Masters quarter-finals on Tuesday.

The 18-year-old, who reached last year's US Open final eight after beating Tsitsipas in the third round, proved too good again for the Greek in one hour and 50 minutes.

Alcaraz reached last week's Indian Wells semi-finals and is now 15-2 on the season, with the win setting up a clash with Serbian Miomir Kecmanovic who upset last week's Indian Wells champion Taylor Fritz 3-6 6-1 6-4.

Tsitsipas broke the Spaniard in the sixth game and led 5-2 before Alcaraz reeled off seven straight games to sensationally take the first set.

Alcaraz surged ahead in the second set, with his defence and speed leaving Tsitsipas short on answers.

The Spaniard, who saved seven of eight break points throughout the match, converted his fourth match point for victory.

"It was really, really tough. He was playing unbelievable," Alcaraz said after the match. "All I can say is I fought until the last ball in the first set [to] come back."

Ninth seed Jannik Sinner won 7-6 (7-3) 6-3 over enigmatic Australian Nick Kyrgios, who had a furious outburst directed at umpire Carlos Bernardes.

The Australian was heard to label Bernardes "an absolute clown" and continued to berate the umpire late in the first set, leading to a code violation and two penalties.

Kyrgios completely lost his cool, demanding to speak to a tournament official before smashing his racquet early in the second set, leading to a game penalty as well.

Sinner will next take on Argentine Francisco Cerundolo after he defeated 28th seed Francis Tiafoe lost 6-7 (2-7) 7-6 (7-3) 6-2.

Top seed Daniil Medvedev made light work of Jenson Brooksby 7-5 6-1 to set up a quarter-final showdown with reigning champion Hubert Hurkacz who won 7-6 (7-3) 6-2 over Lloyd Harris. Medvedev will return to the top of the ATP rankings if he wins their quarter-final.

Second seed Alexander Zverev got past Thanasi Kokkinakis 6-4 6-4 and will meet sixth seed Casper Ruud in the last eight, after the Norwegian won 6-3 6-4 over Briton Cameron Norrie.

The Miami Masters' top seed, Daniil Medvedev, had no problems making his way past Spain's Pedro Martinez 6-3 6-4 to earn his spot in the fourth round.

Serving was the story of the match as the world number two tallied up 14 aces to his unseeded opponent's zero, and only allowed Martinez to see five second serves in the opening set, with Zverev winning all five. Overall, Zverev won 20 of 24 points on serve in the first set.

The second set was more competitive, with Martinez even breaking back after Zverev jumped ahead and looked to coast to victory, but he could not hold off the Russian down the stretch.

Medvedev will play American Jenson Brooksby in his fourth-round matchup after he won a hard-fought 6-3 5-7 6-4 struggle against 15 seed Roberto Bautista Agut.

In a razor-close contest, Brooksby was just slightly better throughout, winning 60 per cent of his service points compared to the Spaniard's 59 per cent, as well as winning 41 per cent of return points compared to Bautista Agut's 40 per cent.

Fresh off his Indian Wells Masters triumph over Rafael Nadal, Taylor Fritz kept his good form going with a 7-6 (7-2) 6-4 win against American compatriot Tommy Paul.

Fritz, who is now up to world number 13, did not have his serve broken all day, winning 81 per cent of his successful first serves (30-37), while also capitalising on the only two break points he saw.

14 seed Carlos Alcaraz only needed two sets to get past 21 seed Marin Cilic 6-4 6-4, creating nine break point opportunities to Cilic's one, which was saved.

In the late session, and in a meeting of rapidly rising prospects, 22-year-old Serbian Miomir Kecmanovic pulled off an upset 7-6 (7-4) 6-3 win over 21-year-old American Sebastian Korda.

Meanwhile, three seed Stefano Tsitsipas was too much for Australian Alex de Minaur, winning 6-4 6-3 after allowing no break point opportunities in the opening set, and saving all three in the second.
