Russian and Belarusian players, including ATP world number one Daniil Medvedev, will still be able to compete on the Tours and at grand slams, but the International Tennis Federation (ITF) has suspended the countries' teams.

Russia's Medvedev was only crowned world number one for the first time on Monday, though that success came amid the backdrop of an ongoing conflict between his nation and Ukraine.

To widespread international condemnation, Russia invaded Ukraine on Thursday, with that conflict since escalating further. Belarus, meanwhile, was effectively used as a staging post for part of the invasion force, though Belarusian president Alexander Lukashenko has insisted the nation's military did not and will not play any part in any operation.

Governments and organisations around the world, including governing bodies within sport, have responded with strict sanctions against Russia and certain individuals with links to president Vladimir Putin.

On Tuesday, the governing bodies of tennis (the ITF, ATP, WTA and the four grand slam events) announced sanctions of their own.

While Medvedev and other Russian and Belarusian players, including Andrey Rublev and WTA world number three Aryna Sabalenka, will be allowed to play in tournaments on both the men's and women's Tours, and the four grand slams, they will have to compete under neutral banners, with the flags of each country banned.

However, the WTA and ATP combined event in Moscow, scheduled to take place in October, has been suspended.

Meanwhile, Russia and Belarus have had their memberships of the ITF revoked, while all ITF tournaments set to be held in those countries have been suspended indefinitely.

Russia hold both the Davis Cup and Billie Jean King Cup.

The immediate upshot of the decision is that Elina Svitolina, the Ukrainian who is top seed at the Monterrey Open, will play her first-round match against Anastasia Potapova on Monday.

Svitolina said earlier in the day that she would refuse to play against any Russian or Belarusian opponent unless all national emblems, flags and colours were removed.

However, prior to the joint announcement from tennis' governing bodies, Svitolina told ITV News: "There's been a lot of discussion.

"Today they will release a statement that they will remove the flags. So we are waiting just for the final confirmation about that. I will be playing tonight because my opponent is going to be under a neutral flag."

Svitolina has pledged to donate all of her prize money from upcoming tournaments to assist Ukraine's fight against Russia.

The statement from tennis' governing bodies read: "A deep sense of distress, shock and sadness has been felt across the entire tennis community following Russia's invasion of Ukraine in the past week.

"Our thoughts are with the people of Ukraine, and we commend the many tennis players who have spoken out and taken action against this unacceptable act of aggression. We echo their calls for the violence to end and peace to return.

"The safety of the tennis community is our most immediate collective priority. The focus of the WTA and ATP in particular in recent days has been on contacting current and former players, and other members of the tennis community from Ukraine and neighbouring countries, to check on their safety and offer any assistance."

Daniil Medvedev has officially been crowned as the ATP's new world number one.

The Russian, who claimed his first grand slam title at the US Open last year and reached this year's Australian Open final, only to lose to Rafael Nadal, has been sure of his place at the top of the rankings since Novak Djokovic's shock defeat to Jiri Vesely in the Dubai Tennis Championships last week.

Medvedev was aiming to cap off a sensational week by claiming victory at the Mexican Open, but the 26-year-old lost to eventual champion Nadal in the semi-finals in Acapulco.

Here, Stats Perform looks at the numbers behind Medvedev's rise to number one.

1 - Medvedev is the first player outside of the "big four" of Djokovic, Nadal, Roger Federer and Andy Murray to be crowned number one since Andy Roddick, way back on February 1, 2004 (18 years, three weeks and six days).

198 - At 198cm in height, Medvedev is the tallest player to be crowned world number one.

13 - Medvedev has won 13 Tour-level titles so far.

27 - He is the 27th different ATP world number one. The first was Ilie Nastase, in August 1973.

3 - Medvedev is the third Russian player to reach the top of the ATP rankings, after Yevgeny Kafelnikov (May 1999) and Marat Safin (November 2000).

6 - At 26, Medvedev is the sixth-oldest player to become world number one for the first time in their career.

361 - Djokovic has held the number one spot for 361 weeks in total – a record. It had been 86 weeks since the Serbian was last not at the top of the pile.

Pedro Martinez secured his maiden ATP Tour title with a 4-6 6-4 6-4 victory over Sebastian Baez at the Chile Open on Sunday.

Both players were competing for their first success in Santiago, with fourth seed Martinez appearing in his second tour-level final after losing to Casper Ruud in Kitzbuhel in July.

World number 72 Martinez sat six places above his opponents in the rankings, but it was seventh seed Baez who claimed the first set before the Spaniard bounced back to send the match to a decider.

Martinez carried that second-set impetus into the final set, eventually triumphing after 2 hours and 48 minutes as he condemned Baez to just his third loss in 29 outings in Chile since the start of the 2021 season.

Rafael Nadal said he will not measure himself against other players' records until his career is over after adding another trophy to his impressive collection, beating Cameron Norrie in straight sets to lift the Mexican Open.

Nadal continued his undefeated start to 2022 with his third title for the year after beating the British sixth seed 6-4 6-4 in Acapulco on Saturday.

He is now on a run of 15-0 this season, claiming his 91st ATP Tour crown along the way.

It was also Nadal's fourth Mexican Open title, having previously won in 2005, 2013 and 2020.

His recent win at the Australian Open put him clear of Novak Djokovic and Roger Federer on 21 grand slam titles, but he still sits behind Ivan Lendl (94), Federer (103) and Jimmy Connors (109) for ATP tournament victories.

After his win in Mexico, Nadal said he is not concerned about records as long as he is still playing, saying: "At the end of the day, I've always said that this kind of record needs to be measured once your career is over.

"Today the most important thing is that I have won a prestigious tournament."

The 35-year-old's incredible form is all the more impressive considering he was forced to miss last year's US Open to deal with a foot issue that troubled him all the way to the lead-up to January's Australian Open.

"It was complicated, and I ended up taking the victory. Looking back, a few weeks ago this would have looked impossible," he added.

"It's amazing how things can change in such a short span, from not being able to practice and now to be where I am today."

Rafael Nadal continued his remarkable start to 2022 with his third title for the year after beating British sixth seed Cameron Norrie 6-4 6-4 in the Mexican Open final in Acapulco on Saturday.

The 21-time major winner extended his 15-0 winning run for the calendar year, claiming his 91st ATP Tour crown along the way. The triumph was also Nadal's fourth Mexican Open title, having also won in 2005, 2013 and 2020.

Nadal, who beat new world number one Daniil Medvedev in the semi-finals and did not drop a set in Acapulco, won in one hour and 54 minutes over a dogged Norrie.

The 35-year-old's achievements are all the more remarkable considering he was forced to miss last year's US Open to deal with a foot issue which troubled him all the way to the lead-up to January's Australian Open.

Norrie pushed the Spaniard, breaking back late in the second set when trailing 5-2, but the defeat ends his eight-game winning streak after lifting the Delray Beach Open title last week.

The Spaniard made 79 per cent of first serves, winning 71 per cent on them, while he converted four of his five break points for the match in typical ruthless fashion.

Nadal claimed the only break of the first set in the fifth game, capitalising on a trio of misses from Norrie.

Both players broke serve early in the second set, with Norrie leading 2-1 before Nadal rattled off four straight games to serve for the crown.

However, Norrie was not done yet, breaking back and holding serve, before the Spaniard finished the job in his 128th appearance in an ATP decider.

Rafael Nadal continued his tremendous form as he beat Daniil Medvedev in straight sets to set up a final with Cameron Norrie at the Mexican Open.

Nadal found this victory over Medvedev to be more straightforward than his remarkable five-set comeback win in last month's Australian Open final between the pair, winning 6-3 6-3 in Acapulco.

The victory means the Spaniard moves on to 14-0 for the new season, which is already his best ever start to a year.

The soon-to-be world number one Medvedev at least made him work for it in the second set and earned 11 break points across two consecutive service games, but a determined Nadal rescued all 11 of them, including seven in a marathon nine-deuce game at 6-3 3-2.

"I played some amazing points on the break points," said Nadal following the win. "The second set was very emotional. Daniil was playing very aggressive – drop shots, winners. It was a very difficult set. I feel lucky to win that set because he had a lot of chances."

He will now face sixth seed Norrie on Sunday, who also came through his semi-final against third seed Stefanos Tsitsipas in straight sets, 6-4 6-4.

The Brit – who won the Delray Beach Open last week – was particularly impressive on his serve, making 92 per cent of his first serves in the opening set. That dropped to 57 per cent in the second, but the quality of his baseline shots took him to victory.

Meanwhile at the Chile Open, local wildcard Alejandro Tabilo continued his good run, having already knocked out top seed Cristian Garin, with a 6-1 6-4 win over sixth seed Miomir Kecmanovic.

Tabilo will face Pedro Martinez in the semi-finals after the Spaniard won 6-2 6-2 over Yannick Hanfmann.

Sebastian Baez will meet second seed Albert Ramos Vinolas in the other semi-final after he got past Facundo Bagnis 7-5 6-2.

Russia's Andrey Rublev wrote "no war please" on a camera lens as he joined compatriot Daniil Medvedev in calling for peace.

Rublev beat Hubert Hurkacz 3-6 7-5 7-6 (7-5) on Friday to progress to the final of the Dubai Tennis Championships.

After confirming his place in a showdown with Jiri Vesely, the 24-year-old world number seven took a pen and scribed "no to war" on the lens of a television camera.

Vesely later wrote 'no war' on a camera lens after defeating Denis Shapovalov to book his place in the final.

It is not uncommon for players to write messages on camera lenses, but a plea for peace was an emotive move from Rublev.

On Thursday, Russia invaded neighbouring Ukraine following weeks of rising political tensions. The conflict escalated further still on Friday, with reports of fighting within the capital city of Kyiv.

Rublev's actions came after Medvedev – who will succeed Novak Djokovic as world number one next week – said he wanted to "promote peace".

Medvedev has reached the final four of the Mexican Open in Acapulco.

Rublev had previously expressed his wish for peace in a news conference at the Dubai event.

"In these moments you realise that my match is not important," Rublev said, with a video clip shared to his official Instagram account.

"It's not about my match, how it affects me. What's happening is much more terrible.

"You realise how important it is to have peace in the world and to respect each other no matter what, to be united. 

"We should take care of our Earth and of each other. This is the most important thing."

Russia's Andrey Rublev wrote "no to war" on a camera lens as he joined compatriot Daniil Medvedev in calling for peace.

After confirming his place in a showdown with either Denis Shapovalov or Jiri Vesely, the 24-year-old world number seven took a pen and scribed "no to war" on the lens of a television camera.

"You realise how important it is to have peace in the world and to respect each other no matter what, to be united. 

"We should take care of our Earth and of each other. This is the most important thing."

 New world number one Daniil Medvedev said he wants to "promote peace all over the world", after the Russian achieved a career highlight amid the crisis in Ukraine.

Medvedev's 6-2 6-3 victory over Japan's Yoshihito Nishioka saw him advance to the final four of the Mexican Open in Acapulco on Thursday, where he will face Rafael Nadal in a repeat of last month's Australian Open final classic.

The Russian advanced shortly after Novak Djokovic's shock loss to Jiri Vesely at the Dubai Tennis Championships, which ensured that he will start next week atop the ATP world rankings for the first time.

The news came shortly after Russian president Vladimir Putin launched a military assault on neighbouring Ukraine, an act that has attracted condemnation from across the sporting world.

"Watching the news from home, waking up here in Mexico, was not easy," Medvedev told reporters.

"By being a tennis player, I want to promote peace all over the world. We play in so many different countries. I've been in so many countries as a junior and as a pro. 

"It's just not easy to hear all this news. I'm all for peace. In these moments, you understand that tennis sometimes is not that important. 

"It was not easy to play and I'm happy that I managed to win the match, but it was a bit of a rollercoaster day for me."

Medvedev's compatriot Andrey Rublev had earlier spoken out in favour of peace, calling the situation "terrible" in an Instagram post.

"In these moments you realise that my match is not important," Rublev's post read. "It's not about my match, how it affects me. What's happening is much more terrible.

"You realise how important it is to have peace in the world and to respect each other no matter what, to be united. 

"We should take care of our Earth and of each other. This is the most important thing."

Rublev teamed up with Ukrainian Denys Molchanov to win the Open 13 Provence doubles title in Marseille just days ago, having also won the singles title at the tournament in southern France.

New world number one Daniil Medvedev says Friday's Mexican Open semi-final against Rafael Nadal is his "chance to get my revenge" after last month's epic Australian Open defeat.

Medvedev progressed to the final four in Acapulco on Thursday with a routine 6-2 6-3 victory over Yoshihito Nishioka, while Nadal triumphed 6-0 7-6 (7-5) over Tommy Paul to set up their semi-final meeting.

The Russian's win capped a fine day after Novak Djokovic's loss to Jiri Vesely at the Dubai Tennis Championships meant he would next week become the new world number one for the first time in his career.

Before then, however, Medvedev must take on Nadal in Acapulco, with the pair having not faced off since last month's epic Australian Open decider, where the Spanish fought back from two set downs to clinch a record-breaking 21st major title.

"It’s always special to play against him,” Medvedev said following his win over Nishioka. “Kind of a chance to get my revenge.

“I have to learn from the best, which is him, Roger [Federer], Novak [Djokovic], Andy [Murray]. Always when they were losing a tough fight, they were trying to get their revenge. Sometimes they managed to do it, sometimes not. That’s what I’m going to try to do if I play Rafa."

Medvedev revealed he did not realise that Djokovic's loss would mean he would become number one until he started receiving congratulatory messages on Thursday.

"It’s not easy to play a match when you get this news during the day," Medvedev said.

"The first goal for me was to still win today because I’m here to try to win every match I play. But it’s definitely some great news."

Nadal was full of praise for the new world number one, admitting his excitement at their re-match.

The Spaniard prevailed in five hours and 28 minutes over Medvedev in Melbourne, winning 2-6 6-7 (5-7) 6-4 6-4 7-5 and was ready for the re-match.

"Everybody knows how difficult it is to play against Daniil," Nadal said after Thursday's win over Paul.

"I know I have to play at my highest level if I want to have any chance, and that's what I'm going to try. I have to play my game.

"Everybody knows how difficult the final was in Australia. Tomorrow is going to be another battle.

"I know he's playing well, plenty of confidence... I am excited to play that match."

Rafael Nadal set up a semi-final meeting with new world number one Daniil Medvedev after cruising past Tommy Paul 6-0 7-6 (7-5) at the Mexican Open in Acapulco on Thursday.

The Spanish fourth seed, who won last month's Australian Open against Medvedev in a five-set epic for a record-breaking 21st Grand Slam title, beat the American in two hours and three minutes.

Nadal was at his tenacious best early, winning the first set 6-0 for the second consecutive match, before Paul hit back in the second.

The Spaniard dropped only 10 points in the opening set with errors creeping into his game early in the second set allowing Paul to get 2-1 up a break.

The pair exchanged a string of four games against serve, with Nadal breaking again with Paul serving for the set, before triumphing in the tie-break.

Top seed Medvedev secured his spot in the last four with a 6-2 6-3 victory over Japan's Yoshihito Nishioka.

Medvedev, who will officially become world number one for the first time in his career next week after Novak Djokovic's loss to Jiri Vesely in Dubai, brushed aside the Japanese in one hour and 10 minutes.

The Russian sent down 12 aces and won 69 per cent on his first serve, while he converted six of eight break points across the match.

Third seed Stefanos Tsitsipas will meet Briton Cameron Norrie in the other semi-final after both triumphed on Thursday.

Tsitsipas won his quarter-final against Marcus Giron 6-3 6-4 in one hour and 17 minutes, while sixth seed Norrie made light work of Peter Gojowczyk 6-1 6-0.

At the Chile Open in Santiago, local top seed Cristian Garin was stunned by countryman Alejandro Tabilo 6-3 6-3.

Sixth seed Miomir Kecmanovic won 6-2 6-0 over Matheus Pucinelli de Almeida, while Yannick Hanfmann eased past Thiago Seyboth Wild 6-1 6-3.

Novak Djokovic has not lost any motivation for tennis, but believes he needs time to find some rhythm after a long break, as he conceded the world number one spot.

Djokovic's 86-week reign at the top of the ATP rankings will end on Monday, after the Serbian lost to qualifier Jiri Vesely 6-4 7-6 (7-4) in the Dubai Tennis Championships.

That means that Daniil Medvedev will leapfrog Djokovic regardless of whether or not he wins in Acapulco.

Using his official Twitter account, Djokovic congratulated both Vesely – who won his only previous meeting with the 20-time grand slam champion back in 2016 – and Medvedev.

"Well played @jiri_vesely, that was a great game. Wish you the best of luck for the rest of the tournament," Djokovic wrote, accompanying his post with a thumbs up emoji.

"Congratulations also to a very deserving @DaniilMedwed, who will now become world number one."

His appearance in Dubai was Djokovic's first competitive action of 2022, after he was unable to feature at the Australian Open due to his refusal to be vaccinated against COVID-19.

While suggesting he is still working his way back to full sharpness after not playing since December, Djokovic insisted he is fully motivated to carry on playing.

"My goal is to keep on playing tennis," Djokovic said in his post-match news conference.

"That's the ultimate goal. For as long as I really feel like it and as long as I can play. As long as my body allows me, as long as the circumstances in my life as well, the people that surround me [and] support me.

"I'm still motivated and I'm still p***** off when I lose a match. I care about it. I care about winning every match, as anybody else on the Tour, regardless of the age. I'm actually glad that I'm feeling a lot of emotions every single day because it means that I really want to be part of this sport, part of the Tour.

"Unfortunately, [it] wasn't my day. I congratulate Jiri. He played better. 

"The more matches I play, the more comfortable I get on the court. I need the match play. I didn't have many matches at all last few months.

"I don't look at the age really as a restricting factor for my career. I still feel great in terms of my body and the way it's holding on, the way it's recovering. It's been serving me well, so to say. That's something that obviously encourages me to keep going."

Daniil Medvedev will become the new world number one after Novak Djokovic was beaten by Jiri Vesely at the Dubai Tennis Championships.

Medvedev entered this week knowing victory at the Mexican Open would see him move to the top of the ATP rankings for the first time.

But the Russian was still waiting to play his quarter-final on Thursday when his ascension was confirmed courtesy of Djokovic's last-eight defeat in Dubai.

Djokovic, a seven-time year-end number one, had led the rankings for 86 consecutive weeks, boosting his record total to 361 weeks.

In his first tournament since missing the Australian Open, however, the five-time Dubai champion struggled to match 123rd-ranked Vesely and went down 6-4 7-6 (7-4).

Djokovic might have known what to expect, having lost his only prior meeting with Vesely in Monte Carlo in 2016.

The Serbian looked like getting to grips with his opponent at the start of the second set, applying pressure, but was then broken again and had to respond strongly to reach a tie-break.

Again, Vesely led, and Djokovic's match was summed up by a double-fault immediately after winning back the mini-break, allowing the Czech to prevail.

The victor hailed the end of Djokovic's reign, saying in his on-court interview: "It's great for tennis to have somebody new as world number one again.

"We all know Novak missed the Australian Open, but he's been such a champion, as world number one for 361 weeks.

"Tennis needs new number ones, new generations coming up, so I think it's just great."

As Vesely advances, second seed Andrey Rublev will fancy his chances of a second straight ATP Tour title after his win at the Open 13 Provence.

Rublev stretched his winning streak to seven matches in coming from behind to beat Mackenzie McDonald and make the semi-finals, where he will play Hubert Hurkacz, who defeated Jannik Sinner.

Rafael Nadal sealed his 12th consecutive win of the new season after a straight sets victory over Stefan Kozlov at the Mexican Open.

Nadal's 12-0 record to begin the year is the best of his illustrious career, and he never looked in any trouble as he eased to a 6-0 6-3 win against the American to advance to the quarter-finals in Acapulco.

The Australian Open champion's next opponent will be Tommy Paul after he beat Dusan Lajovic 7-6 (8-6) 2-6 7-5.

"A little bit of a strange match," Nadal said following his win. "Kozlov has a different style than most other players, so you need to be very careful. Sometimes you are able to win points in a row, but then if you start to play at his rhythm, it's very difficult because he has great control from the baseline and he's very smart."

Number one seed Daniil Medvedev is also safely through after comfortably defeating Pablo Andujar 6-1 6-2, and he will now go up against Yoshihito Nishioka after his victory against Feliciano Lopez.

Stefanos Tsitsipas managed to finish his match against J.J. Wolf in less than 48 minutes as he romped to a 6-0 6-1 win, while his quarter-final opponent Marcos Giron had a much tougher time of it getting past eighth seed Pablo Carreno Busta 6-7 (7-9) 6-4 7-6 (7-4).

Cameron Norrie also came from a set down to beat John Isner 6-7 (2-7) 6-3 6-4, and the sixth seed will now face Peter Gojowczyk after the German received a walkover following his compatriot Alexander Zverev being "withdrawn" from the singles competition after attacking the umpire's chair at the end of his defeat in the doubles.

Meanwhile, in the Chile Open, second seed Albert Ramos-Vinolas beat fellow Spaniard Carlos Taberner 6-2 7-6 (7-4) and will face eighth seed Facundo Bagnis in the quarter-finals after the Argentinian secured a win against Hugo Dellien 6-2 6-2.

Thiago Monteiro fought hard to get past third seed Federico Delbonis with a 3-6 6-4 6-1 victory, and will go up against seventh seed Sebastian Baez in the last eight, who defeated Juan Ignacio Londero 6-3 6-3.

Alexander Zverev saved two match points and battled back to salvage a dramatic victory over Jenson Brooksby at the Mexican Open in what was the latest finish in tennis history.

Second seed Zverev – the defending champion in Acapulco - wrapped up a dramatic win at 04:55 local time after his own lengthy contest had followed two other epic three-setters earlier on the schedule.

Zverev at one stage looked like he was on the way out but ultimately triumphed 3-6 7-6 (12-10) 6-2 to book a second-round tie against Peter Gojowczyk.

The German had beaten Brooksby in a match that also went to a decider when they clashed at Indian Wells in October and he was pushed to the limit again in a battle lasting 200 minutes.

Having dropped the first set, Zverev had to fend off three break points at 3-3 in the second and saved match points at 6-5 and 10-9 down as part of an epic tie-break that went in his favour. 

Zverev was then more comfortable as he broke twice in the decider to seal victory, his American opponent paying the price for converting just one of his seven break-point opportunities in a match that made history for its late finish.

The previous latest ATP finish time was Lleyton Hewitt's 2008 Australian Open clash with Marcos Baghdatis, which ended at 04:34 local time.

Elsewhere, Stefan Kozlov overcame cramps in the second set to outlast Bulgarian Grigor Dimitrov 7-6 (10-8) 5-7 6-3, with that match lasting three hours and 21 minutes.

John Isner sent down 29 aces and saved a match point as he trailed 5-2 in the third set, ultimately winning 7-5 6-7 (4-7) 7-6 (7-3) over veteran Fernando Verdasco in another epic topping the three-hour mark that helped to push back the start time for Zverev and Brooksby.

Seventh seed Taylor Fritz got past Frenchman Adrian Mannarino 6-3 6-3, while Dusan Lajovic knocked off Sebastian Korda 6-4 4-6 7-5 and eighth seed Pablo Carreno Busta beat Oscar Otte in straight sets.

At the Chile Open in Santiago, eighth seed Facundo Bagnis won 6-3 6-0 over Bernabe Zapata Miralles in the round of 32.

Brazilian Thiago Monteiro got past local Nicolas Jarry 7-6 (11-9) 6-4, while qualifier Juan Ignacio Londero and wildcard Thiago Seyboth Wild also progressed.
