Novak Djokovic again overcame the challenge of a fellow home favourite to advance to the semi-finals at the Serbia Open on Thursday. 

The world number one had battled from a set down against Laslo Djere 24 hours earlier and was once more made to work hard for his win versus Miomir Kecmanovic. 

The seventh seed took the opener without facing a break point and led early in the second set too. 

But Kecmanovic could not hold off Djokovic, who recovered to win 4-6 6-3 6-3 and reach the last four for the fourth time in five campaigns in Belgrade. 

After two victories in two nights against Serbians for the two-time winner, Djokovic is on a 10-0 run in matches with his compatriots and 27-4 all-time. 

The 20-time grand slam champion also has a 36-6 record in Serbia and has particularly enjoyed the "strange" opportunity to face his countrymen in front of a home crowd. 

"It's a very strange feeling, sharing the court with your compatriots," he said. "Obviously the crowd was phenomenal for both players in yesterday's match and today's. 

"They're very rare occasions when I'm able to play at home and experience this atmosphere, so I'm trying to enjoy every single moment." 

Djokovic is the last Serbian remaining in the tournament, though, and takes on third seed Karen Khachanov – a winner against Thiago Monteiro – in the semis. 

There remain two quarter-finals to play on Friday, as Andrey Rublev faces Taro Daniel while Fabio Fognini welcomes the challenge of Oscar Otte. 

Meanwhile, there were only two matches completed at the Barcelona Open due to rain, but Ilya Ivashka ensured fans were rewarded for their patience as he took Stefanos Tsitsipas the distance. 

Ivashka eventually went down 6-1 4-6 6-2 to the top seed in a heavily delayed second-round contest. 

Billie Jean King has spoken out against the ban on Russian and Belarusian players imposed at Wimbledon this year as a result of the war in Ukraine. 

The All England Lawn Tennis Club (AELTC) announced on Wednesday that players from the two nations would not be eligible for the grand slam, with the Lawn Tennis Association (LTA) stating it would implement the same rule across all its upcoming tournaments. 

Upon announcing its decision, the AELTC cited a responsibility "to limit Russia's global influence through the strongest means possible". 

The blanket ban rules the likes of Daniil Medvedev, Andrey Rublev, Aryna Sabalenka and Victoria Azarenka out of contention, and that is something King is against. 

She posted on Twitter: "The decision of the LTA and AELTC regarding Russian and Belarusian players at this year's tournament was a difficult and complex undertaking, and I appreciate the challenges and pressures they are facing. 

"One of the guiding principles of the founding of the WTA was that any girl in the world, if she was good enough, would have a place to compete. 

"I stood by that in 1973 and I stand by that today. I cannot support the banning of individual athletes from any tournament, simply because of their nationality. 

"Tennis is stronger when we stand together, and our continue support of the Tennis Plays for Peace initiative, which provides meaningful financial support and resources to Ukraine, needs to be our focus." 

The ATP and WTA criticised the AELTC's decision, while Martina Navratilova and Novak Djokovic have also voiced their opposition. 

In a statement published on Thursday, the Belarusian Tennis Federation (BTF) said it was seeking legal advice. 

"The Belarusian Tennis Federation categorically condemns the decision taken by the organisers of Wimbledon to suspend Belarusian and Russian tennis players. Such destructive actions in no way contribute to the resolution of conflicts, but only incite hatred and intolerance on a national basis," read the release. 

"Throughout the history of tennis, armed conflicts have occurred in the world – in Iran, Afghanistan, Syria, Yugoslavia and other countries – but not until now have tournament organisers suspended athletes from the United States, Great Britain and other countries. 

"Illegal decisions of international tennis organizations in relation to our athletes undermines the reputation of these organisations. 

"Consultations of the BTF leadership with international law firms on sports law are ongoing and a strategy is being developed that is aimed at protecting Belarusian tennis players around the world." 

Novak Djokovic "cannot support" Wimbledon's decision to ban Russian and Belarusian athletes from competition this year.

The All-England Club moved to suspend players from the two nations from entering this year's grand slam event, amid the ongoing Russian invasion of Ukraine.

The decision is the latest major sporting sanction against the two nations, with Russia barred from World Cup qualification for Qatar 2022 and the Formula One Russian Grand Prix cancelled.

It has been met with considerable pushback, however, with the ATP blasting the decision as "unfair".

Now Djokovic has come out against it too, arguing it is not the fault of the players, who are being punished for actions beyond their control.

"I will always be the first one to condemn the war," said Djokovic, who is currently in action on home soil in the Serbia Open. "As a child of war, I know what kind of emotional trauma a war leaves.

"Us in Serbia, we know what was happening here in 1999. Ordinary people always suffer – we've had lots of wars in the Balkans.

"That being said, I cannot support the Wimbledon decision. It's not the athletes' fault. When politics interfere with sport, it usually doesn't turn out well."

Eighteen-time grand slam winner Martina Navratilova also pushed back against the move in an interview on LBC Radio.

"The Russian and Belarusian players, some have even expressed, vocalised, their opposition to the war," she added.

"The only option therefore now for them to play would be to leave their country.

"That’s something that I had to do in 1975, because of a totalitarian regime and now we are asking them to do the same, because of politics, because of optics.

"I understand the banning of teams, of course, representing the countries, but on an individual level, I just think it's wrong."

Novak Djokovic edged into the quarter-finals of the Serbia Open by defeating Laslo Djere 2-6 7-6 (8-6) 7-6 (7-4) in a tense encounter in Belgrade. 

World number one Djokovic was in danger of losing three straight ATP Tour matches for the first time in over four years when he surrendered the opening set to his fellow Serbian in front of an adoring crowd. 

The 20-time grand slam winner was two points away from defeat in the second-set tie-break but managed to force a decider by converting set point at the sixth attempt.

And Djokovic needed another tie-break to get the job done, with Djere paying the price for a series of errors as he missed out on a chance to claim a famous victory. 

Next up for Djokovic, who bounced back from successive defeats to Jiri Vesely and Alejandro Davidovich Fokina in Dubai and Monte Carlo respectively, is Miomir Kecmanovic. 

Seventh seed Kecmanovic faced little resistance from John Millman as he claimed a 6-4 7-6 (7-5) success, while Karen Khachanov was granted a walkover against Roman Safiullin. 

At the Barcelona Open, Carlos Alcaraz advanced to the third round courtesy of a 6-1 2-6 6-2 victory over Kwon Soon-woo. 

He will face Jaume Munar for a place in the quarter-finals following the wildcard's 6-1 6-4 triumph against ninth seed Nikoloz Basilashvili. 

Felix Auger-Aliassime was taken the distance by Carlos Taberner but eventually closed out a 6-1 3-6 6-4 success. His reward is a meeting with Frances Tiafoe, who beat Hugo Dellien 7-6 (7-3) 6-1. 

Lloyd Harris defeated Albert Ramos Vinolas 6-3 6-4, while Alex De Minaur, Emil Ruusuvuori, Pablo Carreno-Busta and Marton Fucsovics also advanced. 

Inclement weather brought a halt to top seed Stefanos Tsitsipas' meeting with Ilya Ivashka after just one game, while Grigor Dimitrov was up a break in the third set of a clash with Federico Coria.

The decision to ban Russian and Belarusian players from Wimbledon is "unfair" and sets a "damaging precedent for the game", the ATP has warned.

An announcement on the grand slam's official website on Wednesday stated that Russian and Belarusian competitors would be barred from the championships, as well as from any other events organised by the Lawn Tennis Association (LTA) this year.

"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," the statement read.

ATP world number two Daniil Medvedev and WTA world number four Aryna Sabalenka headline the list of players who will miss out on the year's third grand slam as a result of the announcement.

The ATP has now hit out at the ban, labelling it "unfair" and discriminatory, while continuing to pledge solidarity with the people of Ukraine.

"We strongly condemn Russia's reprehensible invasion of Ukraine and stand in solidarity with the millions of innocent people affected by the ongoing war," began a press release from the ATP.

"Our sport is proud to operate on the fundamental principles of merit and fairness, where players compete as individuals to earn their place in tournaments based on the ATP Rankings. 

"We believe that today's unilateral decision by Wimbledon and the LTA to exclude players from Russia and Belarus from this year's British grass-court swing is unfair and has the potential to set a damaging precedent for the game. 

"Discrimination based on nationality also constitutes a violation of our agreement with Wimbledon that states that player entry is based solely on ATP Rankings. Any course of action in response to this decision will now be assessed in consultation with our Board and Member councils.

"It is important to stress that players from Russia and Belarus will continue to be allowed to compete at ATP events under a neutral flag, a position that has until now been shared across professional tennis. 

"In parallel, we will continue our joint humanitarian support for Ukraine under Tennis Plays for Peace."

The unilateral announcement from Wimbledon's organisers comes after Russian and Belarusian players were originally allowed to play under neutral flags amidst Russia's invasion of Ukraine, courtesy of a joint ruling from the four grand slams and the ATP and WTA Tours.

Elina Svitolina has called for Russian and Belarusian players to be banned from all international tennis events unless they denounce the invasion in Ukraine.

The All England Club on Wednesday announced that players from Russia and Belarus will not be allowed to compete at Wimbledon due to the conflict in Ukraine.

Daniil Medvedev, Aryna Sabalenka, Victoria Azarenka and Andrey Rublev are among the household names that will not be allowed to compete in the grass-court grand slam, "unless circumstances change materially between now and June".

Russian and Belarusian players will also be prevented from entering all other events organised by the Lawn Tennis Association.

Two-time major semi-finalist and former world number three Svitolina believes a global ban should be imposed on players from Russia and Belarus if they do not speak out.

The Ukrainian former world number three posted on Twitter and Instagram: "Dear Tennis Community.

"Ginetta Sagan once said: 'Silence in the face of injustice is complicity with the oppressor.' This could not be any more true right now.

"On 24th February 2022, Russia, with the support of Belarus, attacked Ukraine. Now there is a war in our country, in our home. All Ukrainians are forced to leave their homes and fight for their lives. For over 50 days now, the Russian forces have been bombing our cities and killing civilians, as well as using the territory of Belarus to bomb Ukraine from the west and the north.

"Millions of people have been left homeless, millions of children now know what explosions, fear and death look like. It is all happening right now in the centre of Europe.

"As athletes we live a life in the public eye and therefore have an enormous responsibility. Some of our posts and opinions on social media reach an audience larger than those of regional television stations. In times of crisis, silence means agreeing with what is happening.

"We noticed that some Russian and Belarusian players at some point vaguely mentioned the war, but never clearly stating that Russia and Belarus started it on the territory of Ukraine. The very silence of those who choose to remain that way right now is unbearable as it leads to the continuation of murder in our homeland.

"We demand that the WTA, ATP and ITF make sure the players who represent Russia and Belarus answer the following questions:

"1. Do you support Russia's and Belarus invasion in Ukraine's territory and as a result of that the war started by those countries?

"2. Do you support Russia's and Belarus military activities in Ukraine?

"3. Do you support [Russian president Vladimir] Putin's and [Belarus president Alexander] Lukashenko's regime?

"If applicable, we demand to exclude and ban Russian and Belarusian athletes from competing in any international event, as Wimbledon already [has] done. There come a time when silence is betrayal, and that time is now."

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.

Dominic Thiem suffered defeat in his first ATP Tour match since June, losing at the Serbia Open to John Millman.

Thiem has been out of action since suffering a right wrist injury and the former world number three was able to claim the second set in his comeback match.

But he could not avoid a 6-3 3-6 6-4 defeat in a contest that lasted two hours and 35 minutes.

Speaking afterwards, Millman said: "It is great to be back here. I was looking forward to coming back and [playing]. All credit to Domi.

"I can't claim it was one of my biggest wins because he is just coming back from injury and I know how hard that is, coming back from three surgeries myself.

"I know it has been tough for Domi but the game is better having him back. Especially on this surface. I have got to take this win because when he gets better and fitter, it is going to be tough."

Next up for the Australian is Miomir Kecmanovic.

NextGen star Jiri Lehecka booked a meeting with second seed Andrey Rublev by beating Henri Laaksonen, while Filip Krajinovic overcame David Goffin.

At the Barcelona Open, fourth seed Cameron Norrie had to come back from a set down to see off Egor Gerasimov, though his 12th seeded fellow Briton Dan Evans lost to Lorenzo Musetti.

There were routine wins for second seed Casper Ruud, sixth seed Diego Schwartzman and 11th seed Lorenzo Sonego.

Cristian Garin was on the end of a shock thrashing by Denmark's Holger Rune in the first round of the Serbia Open on Monday.

The Chilean fifth seed, who was the highest-ranked player in action, is regarded as one of the ATP Tour's best on clay but hardly got a look-in as 18-year-old Rune emerged with an impressive 6-3 6-1 win.

Rune has risen to a career-high 72 in the ATP rankings and showed every sign that he will continue to climb over the season as he produced an aggressive performance that saw him take six of 17 break points.

Playing in only his fifth ATP Tour match on clay, Rune needed just an hour and 25 minutes to see off Garin – the winner of five tour-level titles on the surface – and set up a second-round clash with either Dusan Lajovic or Taro Daniel.

Sixth and seventh seeds Fabio Fognini and Miomir Kecmanovic avoided similar shocks, though their respective wins were wildly different.

Kecmanovic crushed veteran Richard Gasquet 6-0 6-3, while Fognini was forced to overturn a one-set deficit in his defeat of fellow Italian Marco Cecchinato 6-7 (5-7) 6-2 6-2.

No seeds were in action at the Barcelona Open, but Italian prospect Lorenzo Musetti enjoyed a hard-fought 7-5 7-5 defeat of Argentina's Sebastian Baez to seal his spot in the second round.

The 20-year-old is now 5-2 for the clay season and will go up against Dan Evans next. Joining Musetti in progressing is another promising youngster in Brandon Nakashima, who beat Nicolas Alvarez Varona 7-6 (8-6) 6-3 to tee up a clash with number two seed Casper Ruud.

Mackenzie McDonald, Elias Ymer, Kwon Soon-woo and Federico Coria were among the other victors, while retiring 2004 champion Tommy Robredo bowed out with a 6-1 6-1 loss to Bernabe Zapata Miralles.

Stefanos Tsitsipas defended his Monte Carlo Masters crown and lifted his eighth ATP Tour title by defeating Alejandro Davidovich Fokina in straight sets on Sunday.

Greek Tsitsipas, who defeated Andrey Rublev to triumph in Monaco last year, eased past second seed Alexander Zverev in the semi-final and repeated the trick with a 6-3 7-6 (7-3) victory over Davidovich Fokina.

The Spaniard beat Novak Djokovic and reigning Indian Wells Masters champion Taylor Fritz en route to his maiden ATP Tour final, and started well on Court Rainier III with an early break.

However, Tsitsipas found his rhythm with his ferocious forehand to break back before winning four of the next five games to take the lead.

The world number five, appearing in his fourth Masters 1000 final, then failed to serve out for the match at 5-4 up in the second set, but recovered in the tie-break to secure his first trophy of the season.

In doing so, Tsitsipas becomes the sixth player to manage consecutive Monte Carlo titles in the Open Era, while half of his eight tour-level titles have come on clay.

"I am very proud of myself," Tsitsipas said in his on-court interview. "Things weren't going well at one point, but I managed to stay composed to finish the match off.

"I am really proud with the belief I put in my game. Sometimes you doubt yourself, but it is always important to keep your head high."

Davidovich Fokina was aiming to become the first unseeded champion in Monte Carlo since Thomas Muster in 1992, and Tsitsipas acknowledged the 22-year-old made him fight to reclaim the trophy.

"He fought in moments I didn't expect him to fight," Tsitsipas said. "He can hit incredible winners out of nowhere and play unpredictably.

"But I was able to minimise that. I knew he would be a dangerous opponent but that is a great win for me. I think we will see great results from him in the future."

Stefanos Tsitsipas remains on course for a second consecutive Monte Carlo Masters title after recording a straight-sets semi-final win over Alexander Zverev.

The third seed, who defeated Andrey Rublev to clinch the title in Monaco last year, produced a scintillating performance to beat the world number three 6-4 6-2 in Saturday's last-four encounter.

Tsitsipas will face world number 46 Alejandro Davidovich Fokina in Sunday's final, and the Greek said he will need to perform at an even higher level to defeat the 22-year-old, whose incredible run continued with a three-set win over Grigor Dimitrov in the final four.

"It was good," Tstispas told Amazon Prime Video of his semi-final win. "I don't know whether the long match [his three-set quarter-final win over Diego Schwartzman on Friday] gave me some rhythm, but I was able to play good tennis today. I'm happy with the level I was able to execute, and I came up with some good ideas on the court.

"I'm looking forward to the next one, I have a difficult opponent tomorrow, so I need to be ready and to take the best out of this one and move on.

"It's going to take a little bit more [to beat Davidovich Fokina], he's in a good rhythm. I've played him before, and he's a difficult opponent, I'm going to be as ready as possible, he's definitely improved and I'm going to have to produce the best tennis I can."

Davidovich Fokina, who has made headlines by eliminating Novak Djokovic and Indian Wells Masters champion Taylor Fritz during a thrilling run in the municipality, beat Dimitrov 6-4 6-7 (2-7) 6-3 earlier on Saturday, reaching his first ATP Tour final.

The unseeded Spaniard needed two hours and 43 minutes to wrap up his semi-final contest, and revealed that a bathroom break allowed him to reset his mind and clinch a hard-fought victory after he failed to serve out the second set at 5-4 up.

"I am so happy to be in the final, it's a dream come true to try to have the title," he said after the win.

"When I was a kid, I was dreaming about this day and it's come true, I'm so happy.

"In the second set I had my chances, I was so tight. But I went to the bathroom [after the second set] and I said to myself 'I want this'. Now I am in the final, I will enjoy, I have all the power with me."

Reigning Monte Carlo Masters champion Stefanos Tsitsipas will have to overcome Alexander Zverev if he is to have the chance to defend his title.

Zverev, who is ranked third in the world - two places higher than Tsitsipas - fought back to defeat Jannik Sinner 5-7 6-3 7-6 (7-5) in his quarter-final match, denying his opponent another top-five seed scalp following his prior win over Andrey Rublev.

"It means a lot, definitely, especially [with] how this year has been going so far for me," said Zverev after a gruelling three hours on court.

"I've lost long matches like that, so I’m happy I won this one."

Tsitsipas also orchestrated a superb turnaround against Diego Schwartzman, prevailing 6-2 6-7 (3-7) 6-4.

The Greek had looked set for a last-eight exit at four games down in the final set, only to stage a dramatic comeback to keep his hopes of a first title since last May's Lyon Open alive.

"There was a moment in the match where I felt what I was doing wasn't working," Tsitsipas said.

"He had a massive lead and momentum in what he was trying to do. I just tried to stay in the match as much as I could and that worked out very well.

"I wasn't expecting much at that point being a double break down, so I relaxed at that point."

Schwartzman meanwhile will rue his inability to put the tie to bed, having already reached two ATP finals this year.

Grigor Dimitrov and Alejandro Davidovich Fokina will face off in the other semi-final.

Bulgarian Dimitrov beat off Hubert Hurkacz in another final-set tie-break, winning 6-4 3-6 7-6 (7-2).

Fokina, who eliminated Novak Djokovic in the second round, turned over Indian Wells champion Taylor Fritz in another comeback result, triumphing 2-6 6-4 6-3.

Alexander Zverev and Stefanos Tsitsipas progressed to the quarter-finals of the Monte Carlo Masters with straight sets wins on Thursday, remaining on course for a final meeting.

Last year's runner-up Andrey Rublev, however, missed out on a last-eight spot after falling to a three-set defeat against Jannik Sinner.

World number three Zverev overcame Spain's Pablo Carreno Busta 6-2 7-5 to progress in Monaco, where he is seeking to win the sixth ATP 1000 title of his career.

"For the second clay-court match of the season, I can't complain too much," the 24-year-old second seed said on court after sealing the victory.

"Yes, I lost focus a little bit in the second set, but at the end of the day, he's somebody that can really play. I'm happy with a two-set win."

Tsitsipas (3) remains in contention for a second consecutive title in the principality after defeating Laslo Dere 7-5 7-6 (7-1) and will face off against 12th seed Diego Schwartzman for a semi-final spot after the Argentine defeated Lorenzo Musetti in a hard-fought three-set encounter.

There will be no repeat of 2021's final between Tsitsipas and Rublev, however, after the Russian fell to a thrilling 5-7 6-1 6-3 loss to ninth seed Sinner in the day's final contest.

The other seed to fall victim to a shock in the last 16 was world number seven Casper Ruud, losing 6-3 7-5 to Grigor Dimitrov, who will face Poland's Hubert Hurkacz in the last eight. 

Finally, Novak Djokovic's conqueror Alejandro Davidovich Fokina cruised past David Goffin 6-4 6-1 to set up a quarter-final tie with the United States' Taylor Fritz, who bested compatriot Sebastian Korda – with whom he played doubles with in Monte Carlo – in straight sets.

Lorenzo Musetti headlined a day of shocks at the Monte Carlo Masters as Felix Auger-Aliassime fell to a first-round defeat.

Auger-Aliassime already has one singles title to his name this year, having prevailed in Rotterdam, and also reached the final of the Open 13 in Marseille and helped Canada to victory in the ATP Cup at the start of 2022.

However, the sixth seed entered this contest with just one win from his last four matches and came unstuck once again at the hands of Musetti. 

Musetti, who won two sets in the fourth round of the French Open against Novak Djokovic last year, is very much at home on the clay in Monaco.

He demonstrated that in 6-2 7-6 (7-2) success, setting up a last-16 meeting with Diego Schwartzman.

“I live here and practice here,” Musetti said in his on-court interview. "It is nice to be here and play here in front of such a crowd. I am really happy.

"My backhand down the line was a key to many of my great shots. After a really good first set, he came back with such powerful serving, but I was calm and patient and that was the most beautiful thing about today."

Auger-Aliassime's exit came a day after top seed Djokovic was knocked out in the second round by Alejandro Davidovich Fokina, but there were no such problems for second seed Alexander Zverev as he saw off Federico Delbonis in straight sets.

Fifth seed Andrey Rublev came from a set down to defeat Alex de Minaur and fourth seed Casper Ruud, coming off his defeat in the final in Miami, edged qualifier Holger Rune in two tight sets.

The man who vanquished Ruud in Florida will go no further on the Cote d'Azur, however, Carlos Alcaraz losing in just over three hours to Sebastian Korda on his Monte Carlo debut.

Korda lost to Alcaraz in the final of last year's Next Gen ATP Finals, but avenged that defeat with a 7-6 (7-2) 6-7 (5-7) 6-3 victory.

World number 10 Cameron Norrie lost to Albert-Ramos Vinolas and his British compatriot Dan Evans fell to David Goffin, while 16th seed Lorenzo Sonego was beaten by the in-form Laslo Djere.

Elsewhere in the draw, there were wins for Jannik Sinner, Taylor Fritz, Hubert Hurkacz and Pablo Carreno Busta.

World number one Novak Djokovic explained that he could just not get up to the level of sharpness required in his shock defeat at the Monte Carlo Masters.

Djokovic slumped out in the second round on Tuesday when he lost 6-3 6-7 (5-7) 6-1 to world number 46 Alejandro Davidovich Fokina.

The Serbian's status as an unvaccinated player has limited his ability to compete on the ATP Tour this year and he has played in just one tournament so far, getting to the quarter-finals in Dubai. 

Yet his preparations for the French Open, which starts at the end of next month, hardly got off to a good start as he made 51 unforced errors in what was still, despite his rustiness, a surprise defeat.

"I didn't like the way I felt physically in the third. I just ran out of the gas completely," Djokovic told the media. 

"Just couldn't really stay in the rally with him. I mean, if you can't stay in the rally, not feeling your legs on the clay, it's mission impossible.

"I'm going to look with my team into reasons why that was the case and go back to the drawing board. Hopefully next week will be better in Belgrade."

Though Djokovic has won twice in Monte Carlo, it has not been a happy hunting ground for him in recent years. He has not advanced past the quarter-final stage since 2015.

He added: "It's going to take some time for me to really feel my best on the clay.

"That's historically always been the case. [I have] never played very well in the opening tournaments of the clay season.

"But it's okay. Obviously it is what it is. I have to accept the defeat and keep working."

While unhappy with his own performance, Djokovic had nothing but praise for his opponent. 

"I would like to congratulate Alejandro. He was the better player," Djokovic said. "He managed to find a better rhythm I think in the first two sets. I was hanging on the ropes the entire match. I was really chasing the result constantly.

"I always believed that I could come back and win the match, and I stayed there even though a lot of things were against me in terms of how I felt on the court. Game-wise, physically I was just far from my best.

"I expected this match to be [a] really tough match, [a] physical battle, and that's what it was. Unfortunately I'm on the shorter end of the stick, and my week ends here."

Djokovic's defeat also means a mouthwatering contest with teenager sensation Carlos Alcaraz, who he might have met in the quarter-finals, will not be taking place.
