Tokyo Olympics gold medalist Alexander Zverev has been issued a suspended eight-week ban and $25,000 fine by the ATP following his expulsion from last month's Mexico Open in Acapulco.

Zverev was withdrawn from the Acapulco event after an extraordinary outburst during a doubles match where he became angered at a call made the umpire, who overruled a decision from the line judge.

After losing the next point, which was match point, Zverev smashed his racquet against the umpire's chair three times. Zverev then shouted at the umpire that he had "destroyed the whole f****** match" before striking the chair again.

The ATP subsequently withdrew Zverev from the singles draw of the event due to unsportsmanlike conduct at the time and issued a statement on Monday after a review detailing the sanctions, including a suspended eight-week ban for aggravated behaviour.

"The review determined that Zverev committed Aggravated Behaviour under the Player Major Offense section of ATP Rules," the ATP statement said.

"As a result, Zverev has been issued an additional fine of US$25,000 and a suspension for a period of eight weeks from any ATP-sanctioned event.

"However, the fine and suspension are withheld on the condition that, over a probation period ending 22 February 2023 (one year from the incident), the player does not incur a further Code Violation that results in a fine for unsportsmanlike conduct… and verbal or physical abuse."

The German had been fined $40,000 at the time as well as forfeiting full event prize money of $31,570 and all ATP rankings points from the Mexico Open. He has since apologised for his actions.

Novak Djokovic has confirmed his professional partnership with long-time coach Marian Vajda has come to an end.

Djokovic revealed the pair agreed to part ways last year following the ATP Finals in Turin.

Vajda served as part of Djokovic's team for 15 years, playing a pivotal role in the 20-time grand slam champion's glittering career.

"Marian has been by my side during the most important and memorable moments in my career," Djokovic said in a post on his official website.

"Together we have achieved some incredible things and I am very grateful for his friendship and dedication over the last 15 years.

"While he might be leaving the professional team he will always be family and I can't thank him enough for all he has done."

Vajda said: "During my time with Novak, I have been lucky to watch him transform into the player he is today.

"I will look back on our time together with immense pride and am so very thankful for the success we have achieved.

"I remain his biggest support on and off the court and look forward to new challenges."

Vajda was joined on Djokovic's team by former Wimbledon champion Goran Ivanisevic in 2019. Ivanisevic will continue working with Djokovic as he bids to add to his tally of major triumphs.

Djokovic, who is unvaccinated against COVID-19, missed the 2022 Australian Open after having his visa cancelled on "health and good order grounds", leading to his deportation.

Rafael Nadal's triumph in Melbourne gave the Spaniard the outright record for grand slam triumphs with 21.

Djokovic made his 2022 debut in Dubai last month, losing in the quarter-finals to Jiri Vesely. On Monday, he was usurped as world number one by Daniil Medvedev.

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.

Andrey Rublev cruised to the Dubai Tennis Championship title with a 6-3 6-4 final victory to end the dream run of qualifier Jiri Vesely.

Having made headlines after his semi-final triumph over Hubert Hurkacz by writing "no war please" on a television camera in protest at Russia's invasion of Ukraine, Rublev wrapped up his third title in just a matter of days in emphatic fashion, after winning both the singles and doubles titles at the Open 13 Provence in Marseille last week.

The Russian world number seven had needed three sets in each of his last three contests but wrapped up a more straightforward victory against his Czech opponent, who had defeated 20-time Grand Slam champion Novak Djokovic en route to the final.

Rublev broke Vesely's serve in the fourth game of the contest, not dropping a single point behind his first serve as he roared to a 6-3 win in the opening set.

The 24-year-old then broke again in the opening game of the second set, before the Czech, ranked number 123 in the world, battled back bravely to level the set at 3-3.

Rublev responded in brutal fashion, however, immediately breaking again and going on to seal a comfortable victory, hitting just eight unforced errors throughout the contest, as he claimed his 10th career title.

The victory made it 13 match wins in a row for Rublev across singles and doubles after his successful time in Marseille, where he successfully teamed up with Ukrainian Denys Molchanov for a symbolic doubles triumph.

"I was lucky today, and that's why I am happy to be the champion, I didn't expect this," said Rublev. "It's an amazing feeling and I don't know what to say."

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.

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

"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."
