Daniil Medvedev reached the first grass-court final of his career as he saw off Pablo Carreno Busta at the Mallorca Championships.

Medvedev, the top seed, had to come from a set down against his Spanish opponent, winning 3-6 6-3 6-2 to tee up a showdown against Sam Querrey.

The world number two has won 10 ATP Tour titles, but they have all come on hard courts.

"I know that I can play well on grass," said Medvedev, who followed up a quarter-final run at Roland Garros with a first-round defeat to Jan-Lennard Struff at the Halle Open.

"Unfortunately we don't have that many tournaments, only one ATP 500 and one grand slam. It's going to be a special feeling [if I] win my first title on grass.

"I still don't have one on clay, even if I have one final. Adding these titles, especially on different surfaces, can help your confidence and it’s just a great thing for your career."

World number 13 Carreno Busta had looked sharp in successive straight-set wins en route to the semi-finals, and started Friday's encounter in good form.

He had not dropped serve across the first four sets of his campaign in Mallorca and extended that streak by saving three break points in the opening set.

However, Medvedev – who has been drawn in the same half as Roger Federer at Wimbledon – rallied and served out the one-hour, 56-minute victory with an ace.

Querrey, meanwhile, will be going for his first ATP Tour title since 2017 after he cruised to a 6-4 6-3 win over unseeded Adrian Mannarino.

Another player who is hunting for his first Tour triumph on grass is Alex de Minaur, who defeated Soon Woo Kwon 6-3 7-6 (7-2) to progress to the Viking International final.

The world number 18 has won four hard-court titles and will go up against Lorenzo Sonego for the crown in Eastbourne.

Sonego beat De Minaur's compatriot Max Purcell 6-1 3-6 6-1. The Italian triumphed at the Sardegna Open in April.

Novak Djokovic will start the defence of his Wimbledon title against British wildcard Jack Draper, and Serena Williams takes on Aliaksandra Sasnovich in the first round.

Djokovic is just one grand slam title away from matching Roger Federer and Rafael Nadal's record tally of 20 after winning the Australian Open and French Open this year.

The world number one will take on 19-year-old Draper, a quarter-finalist at Queen's Club last week, in his first match at SW19 for two years after the 2020 championships were called off due to the coronavirus pandemic.

Djokovic faces a potential quarter-final against Andrey Rublev, while Federer could come up against second seed Daniil Medvedev in last eight.

First up for eight-time Wimbledon champion Federer is an encounter with Adrian Mannarino, while injury-plagued two-time winner Andy Murray will start his home major against the 24th seed Nikoloz Basilashvili.

Stefanos Tsitsipas, beaten by Djokovic in a thrilling French Open final this month, has been drawn to face American Frances Tiafoe in round one of a tournament that gets under way on Monday.

Simona Halep announced just before the draw was made on Friday that she would not defend her title due to a calf injury.

Williams, runner-up to Halep in the 2019 final, must get past Sasnovich of Belarus in the first round and could face third seed Elina Svitolina at the quarter-final stage.

World number one and top seed Ash Barty takes on Carla Suarez Navarro, who made a grand slam return at Roland Garros after recovering from cancer. Barty could come up against Bianca Andreescu in the last eight.

Petra Kvitova against Sloane Stephens is a standout first-round match, while Coco Gauff's first assignment will be a meeting with 20-year-old Briton Fran Jones.

Daniil Medvedev is set for just the third grass-court semi-final of his ATP Tour career at the Mallorca Championships.

Medvedev, who has reached two hard-court grand slam finals, as well as winning last year's ATP Finals, has never been beyond the last four on grass. He has only done so once on clay.

The Russian will get another chance on Friday, though, against Pablo Carreno Busta.

That is his reward for beating Casper Ruud, who Medvedev acknowledged likely also does not favour the grass season.

"I don't think grass is his best surface, but in the first set he was playing top level and I couldn't get any break points," Medvedev said after beating Ruud 7-5 6-1. 

"But as soon as he started serving a bit worse and making some errors, I tried to use it as fast as I could.

"It was important to win the first set and not in a tie-break, this gives me a boost of confidence."

Carreno Busta defeated Jordan Thompson in straight sets but was not followed into the semis by either of the other Spaniards in action.

Third seed Roberto Bautista Agut was toppled by Sam Querrey, as Feliciano Lopez lost to Adrian Mannarino.

At the Viking International in Eastbourne, there is an Australian in each semi-final after wins for Alex de Minaur and Max Purcell.

De Minaur wore down Vasek Pospisil 6-4 6-4 and now faces Kwon Soon-woo, who was similarly comfortable against Ilya Ivashka.

Purcell battled past Andreas Seppi, recovering from a tough second set in which he succumbed 6-1, but must now face another Italian.

Third seed Lorenzo Sonego secured his semis spot by blasting past Alexander Bublik 6-1 7-5.

Dominic Thiem has been ruled out of Wimbledon after tests on a wrist injury and faces a race to be fully fit in time to defend his US Open title.

The world number five retired from his match against Adrian Mannarino in the Mallorca Championships on Tuesday, when 5-2 up in the opening set.

Checks on the wrist by a specialist in Barcelona have shown Thiem needs time away from tennis, meaning Wimbledon is off the table along with tournaments in Hamburg and Gstaad in July.

According to a medical bulletin issued on Thiem's social media accounts, it will be five weeks before he can remove a wrist splint and begin to step up his recovery.

With the US Open beginning on August 30, that does not leave a lot of time for Thiem to recover physical fitness and find his best tennis. He would have been seeded number four at Wimbledon.

The medical bulletin read: "Tests found that there is a 'detachment of the posterior sheath of the ulnar side of the right wrist', an injury that will not allow him to compete in the circuit for several weeks.

"Thiem will wear a wrist splint for five weeks before beginning a progressive process of specific, functional rehabilitation to regain mobility as well as muscle strength in his wrist and ultimately return to training on court."

Thiem, who had already decided against playing at the upcoming Tokyo Olympics, appears to be hoping his lay-off is not as long as the experts have forecast.

He will undergo MRI scans and tests as his recovery progresses, and the 27-year-old Austrian said: "I'm going to do everything the doctors say in order to recover as quickly as possible.

"They've informed me that I might be out for several weeks, but I will do my best to be back on court soon.

"I'm really sorry for pulling out of the upcoming three tournaments I had in my calendar: Wimbledon, Hamburg and Gstaad.

"They are very important tournaments for me. I appreciate all the support from the fans in these difficult moments – I'm determined to come back stronger."

Thiem's absence is another blow for Wimbledon, with Rafael Nadal and Naomi Osaka having already announced they would not be playing the tournament.

Dominic Thiem will seek the advice of a specialist in Barcelona after suffering an injury scare ahead of Wimbledon next week.

Number two seed Thiem retired due to a wrist injury when 5-2 up in the opening set against Adrian Mannarino in the Mallorca Championships on Tuesday.

An MRI conducted at a Mallorca hospital was inconclusive, so the US Open champion will now undergo further tests.

In an update on Wednesday, Thiem wrote on social media: "Yesterday during the match I had a problem with my wrist.

"I went immediately to do an MRI at the hospital in Palma de Mallorca. The results weren't that clear and I have decided to go to Barcelona to check with a specialist.

"I hope I can get the results and a clear diagnosis in the next days."

The ATP 250 event continued without him in Mallorca, as Roberto Bautista Agut moved into the quarter-finals with a 6-3 7-5 triumph over Italian Stefano Travaglia.

More Spanish success on home soil arrived as Pablo Carreno Busta won 6-4 6-4 against Jiri Vesely.

In the doubles, Novak Djokovic and Carlos Gomez-Herrera saw off top seeds Marcel Granollers and Horacio Zeballos to reach the last four in that competition.

Djokovic appears to be enjoying himself as he continues to prepare for Wimbledon, saying: "This was a huge win for us, beating one of the best doubles players in the world after losing the first set.

"We are having a lot of fun on the court. I thought we played well even though we lost the first set."

There was a major upset at the Viking International in Eastbourne, meanwhile, with number one seed Gael Monfils suffering a shock last-16 defeat to Australia's Max Purcell – ranked number 283 in the world.

Purcell, who is only in the tournament as a lucky loser, claimed a huge 6-4 5-7 6-4 win in a battle lasting over two hours.

Monfils fired down 16 aces and fought back after being within two points of defeat in the second set but was ultimately beaten and has not made an ATP quarter-final since February 2020.

"It feels unbelievable," said Purcell. "I thought I'd come out and have a go. 

"I've struggled to get into any singles events over the past nine months and primarily played doubles, so to get on a run here, on my favourite surface, is great."

Purcell will take on Andreas Seppi – a comfortable winner over Emil Ruusuvuori – in the last eight.

While Monfils crashed out, there was less drama for the second and third seeds. 

Alex de Minaur won 6-3 6-4 against home hope Liam Broady, while Lorenzo Sonego was a 6-4 6-2 victor in his contest with John Millman.

Feliciano Lopez reached the milestone of 500 ATP Tour wins with a comeback victory over Karen Khachanov at the Mallorca Championships.

Lopez, who turns 40 in September, prevailed 4-6 6-2 6-4 against the sixth seed.

He is the 10th active player to reach 500 wins, after Roger Federer, Rafael Nadal, Novak Djokovic, Andy Murray, Richard Gasquet, Fernando Verdasco, Marin Cilic, Stan Wawrinka and Tommy Robredo.

"More than the 500 wins, the important thing to me is the chance to keep playing in these kinds of tournaments and to keep being competitive," Lopez told ATPTour.com.

"I didn’t expect to be able to play at the level I am on the ATP Tour at 40 years of age, which I will be in September."

Spanish veteran Lopez would have expected to be taking on Dominic Thiem next, but the world number five retired due to a wrist injury when 5-2 to the good in the opening set against Adrian Mannarino.

"It's nice for me to be in the quarter-finals, but winning this way is not so cool. I really like Dominic, he's such a nice guy and I hope he will be feeling better soon," Mannarino said. "I hope it is not so serious, especially right before Wimbledon."

Elsewhere on the Balearic island, top seed Daniil Medvedev breezed past Corentin Moutet 6-4 6-2, while Casper Ruud defeated Tennys Sandgren in straight sets.

At the Viking International in Eastbourne, there were mixed fortunes for Lopez's countrymen Alejandro Davidovich Fokina and Albert Ramos-Vinolas.

Fokina, seeded sixth, saw off Mikael Ymer 7-5 6-1, but number seven seed Ramos-Vinolas fell 6-4 6-3 to Emil Ruusuvuori.

Alexander Bublik defeated fellow Kazakh Mikhail Kukushkin is straight sets, while Jo-Wilfred Tsonga went down in similar fashion against Egor Gerasimov.

Andy Murray is hopeful 2021 will prove not to be his last appearance at Wimbledon.

The two-time tournament winner has been handed a wildcard for the grass-court grand slam in London, which was cancelled last year due to the coronavirus pandemic.

Murray also missed the 2018 and 2019 tournaments due to injury, so this year will be his first Wimbledon outing since reaching the quarter-finals in 2017, when the ailing Briton suffered a five-set defeat to Sam Querrey.

Ahead of his first Wimbledon appearance in four years, the 34-year-old hopes to play in many more, though he will savour the experience and take nothing for granted given his recent injury woe.

"To me it's not so much about me worrying about it being my last one, it's just something that I think about," Murray told Sky News.

"I don't want it to be my last Wimbledon, certainly I want to keep playing, I don't want to stop just now, so yeah I want to keep going.

"I've had so many injuries and so many setbacks you just don't really know what's round the corner.

"I want to approach each tournament and each match that I play like it's my last one so that I can get the most out of it.

"So that's why I want to prepare here well. I'm going into the bubble on Wednesday evening so I'm going to get there early to practise at Wimbledon. 

"Hopefully I've got some high quality practices – I'm practising with Marin Cilic and I practise with Roger Federer later in the week.

"I'm just trying to play with high quality grass court players to prepare me as best as possible." 

Murray, who has undergone two hip surgeries since he last played at Wimbledon, earned an impressive win on the grass over Benoit Paire at Queen's last week.

He then lost in straight sets to eventual champion Matteo Berrettini in round two.

As long as he can prepare properly and remain competitive, three-time grand slam champion Murray, who has also previously won the US Open, wants to battle on.

He added: "It's more about the body if I'm restricted in how I can prepare. 

"If I can't prepare properly to compete then that's when it's not fair on yourself to keep putting yourself out there, because you're not properly prepared and can't do yourself justice.

"So if that was the case and I was having to compromise on my training just to get out there on a match court and my results weren't good – that is something I'd look at. 

"But providing I can train and prepare well and I'm enjoying it I'll do it for as long as I can."

Fifth seed Casper Ruud secured his place in the last 16 of the Mallorca Championships with a straight sets win over Gilles Simon on Monday.

The 22-year-old claimed a 6-4 7-6 (7-4) victory to set up a meeting with Tennys Sandgren in the next round.

Following Ruud onto Centre Court, the American beat Spain's Jaume Munar 7-6 (7-3) 7-5 in just over two hours.

Sixth seed Karen Khachanov is also safely through, although he surrendered a set in beating French qualifier Lucas Pouille 7-6 (9-7) 3-6 6-4.

But Dusan Lajovic, seeded eighth, was not quite as fortunate.

Lajovic, ranked 41st in the world, was beaten 6-4 7-6 (7-2) by Slovakian qualifier Lukas Klein (ranked 256).

Feliciano Lopez came out on top of battle of Spaniards in the round of 32, beating Nicola Kuhn 6-1 7-6 (7-4).

Their compatriot Roberto Carballes Baena is in with a chance of joining them on Tuesday after seeing his clash with Sam Querrey paused due to light with both players having taken a set.

Elsewhere, Corentin Moutet beat Lloyd Harris to set up a meeting with top seed Daniil Medvedev, while Jiri Vesely and Stefano Travaglia also progressed.

Monday's other scheduled ATP event in Eastbourne saw play cancelled due to rain, with the scheduled match between Jo-Wilfried Tsonga and Egor Gerasimov pushed back as a result.

Matteo Berrettini became the first Queen's Club Championships debutant to carry off the singles trophy since Boris Becker, as the Italian landed the biggest title of his career.

The world number nine beat British hope Cameron Norrie 6-4 6-7 (5-7) 6-3 in the London showpiece match on Sunday, setting himself up ideally ahead of a Wimbledon mission later this month.

Whereas Becker was 17 when he triumphed at Queen's Club in 1985, going on to be champion at Wimbledon just weeks later, Berrettini is 25 years old and established as a leading player.

His big serve – an aspect of his game he shares with vintage Becker – proved a huge asset against Norrie as Berrettini served 19 aces and won 91 per cent of points when landing his first delivery.

Norrie could not forge a break point but did commendably well to force a deciding set in a match that lasted three minutes short of two hours.

Berrettini said he had experienced an "unbelievable week", lifting his first title at ATP 500 level, and he was blown away by the Becker link.

"If I think about his name and my name, it's crazy," he said in an on-court interview.

"I was dreaming about playing this tournament. I was watching when I was a kid and now I had the chance to lift the trophy. It's a dream come true."

Berrettini could be a threat to anyone if his serve fires at Wimbledon, and he was proud of how he fended off Norrie.

"I didn't check the numbers during the match. I knew I was serving well," said Berrettini. "I knew it was important because in the rallies this guy is dangerous. I knew I had to play my best tennis."

Berrettini said his celebrations were likely to be muted, given he is in a pre-Wimbledon bubble, predicting his team would limit his post-match treats to "probably room service and sparkling water".

There would be cause for greater cheer if Berrettini goes on a run at the All England Club, with Wimbledon due to begin on June 28. His previous best performance at Wimbledon was a run to the fourth round two years ago.

Berrettini told Amazon Prime: "I know it's going to be a really tough tournament.

"Probably all the players have extra motivation to play well there so it's going to be tough, but I have a lot of confidence."

Ugo Humbert upset the odds by overcoming Andrey Rublev to win the Halle Open title, clinching his first ATP 500-level trophy in the process.

Unseeded Humbert already claimed the scalp of Alexander Zverev earlier in the week and, having seen off Felix Auger-Aliassime to reach the final, came out on top against world number seven Rublev 6-3 7-6 (7-4).

Rublev was appearing in his eighth final since the start of 2020, though it was his first on grass. The Russian was seeking a fifth successive victory in an ATP 500 level final, yet ultimately came up short, meaning Humbert made it three wins from three in his career finals.

The 22-year-old won his first two titles – in ATP 250 events in Antwerp and Auckland – last year.

Humbert's victory took just 87 minutes, with the Frenchman winning 45 of 53 points on his first serve.

The only break of the game went Humbert's way when he struck to make it 5-3 in the first set before holding off two break points in the next game to take the lead.

Neither player offered a single break point in the second set, and it was Humbert who nosed himself in the tie-break to secure a third career triumph, becoming the first player to win the Halle Open on his debut at the tournament since Lleyton Hewitt defeated Roger Federer in 2010.

Humbert's win will also take him up six places in the ATP rankings, from 31 to 25.

Matteo Berrettini continued his impressive charge at the Queen's Club Championships as he booked a place in the final against Cameron Norrie.

Top seed Berrettini, ranked nine in the world, has not dropped a set all week.

His impressive run has seen him defeat home hopes Andy Murray and Dan Evans, with one more Briton in the shape of Norrie left to see off in his bid for glory.

Berrettini ensured he will be in the final by claiming a 6-4 6-4 triumph over fourth seed Alex de Minaur in the semi-final on Saturday.

The Italian dropped just four of his 36 points on first-serve and sent down eight aces, with De Minaur only able to force one break point in the entire contest, which he did not take.

"[Making the final] was the goal of the week and now I have one more step," said Berrettini.

"It is a great achievement, especially for the history of this tournament. I am really happy because to beat Alex, I had to play my best tennis."

Berrettini has four tour titles to his name, though this would be his first at ATP 500 level or above.

Victory would also represent the biggest win of Norrie's career – he has lost each of his three previous finals, all at ATP 250 level.

Norrie impressively eliminated Denis Shapovalov to reach the showpiece, beating the Canadian 7-5 6-3.

Shapovalov had earlier finished off a 6-3 6-4 quarter-final win over Frances Tiafoe, a match that could not be completed on Friday due to fading light.

But the second seed could not muster up another victory against a fresher Norrie.

At the Halle Open, Andrey Rublev reached his eighth final since the start of 2020, though his first on a grass court.

Rublev dropped his first set of the week but ultimately prevailed with a 6-1 3-6 6-3 semi-final victory over Nikoloz Basilashvili.

The Russian has won his last four finals at ATP 500 level and will seek a fifth on Sunday.

"It's my first final on grass and in Halle," he said. "I think I can play on every surface and I will try my best again.

"I had good opportunities to break Basilashvili in the second set, some quite easy forehands and I stressed a little showing my emotions. 

"I then came back and stayed calm, until the last game. But I won."

Rublev will take on unseeded Ugo Humbert, who held his nerve to edge a thriller against Felix Auger-Aliassime, winning 6-4 3-6 7-6 (7-5).

Humbert beat Alexander Zverev earlier in the week and has had to win a deciding set in all four rounds, while the beaten Auger-Aliassime had previously seen off Roger Federer as part of a dramatic event.

Frenchman Humbert won each of his first two career finals, which both took place last year in ATP 250 events.

Top seed Matteo Berrettini has his sights set on the Queen's Club Championships title after beating Dan Evans in the quarter-finals.

After a delay of more than four hours because of rain in London, Berrettini overcame Evans 7-6 (7-5) 6-3 to reach his third ATP grass-court semi-final.

The Italian hit 13 aces and won 81 per cent of his first-serve points against Evans to set up a last-four clash with Alex de Minaur. 

Berrettini improved his win-loss record to 24-6 for the season and laid out his ambition to walk away from the tournament with the trophy.

"I didn't serve that well, but I was returning well and I just played better in the last few points of the tie-break," he said.

"After that, I felt more confident. The conditions were really tough, windy and cold, so I took time to adapt a little bit. I am pretty happy with my performance.

"The court condition was really good. I expected slippery conditions, but it was like yesterday.

"I came here to win the tournament, that is my goal. Now I am two steps away. I am happy with the way I am playing, and my mental attitude is really good."

Up next for Berrettini is Australian De Minaur, who came from behind to defeat Marin Cilic 3-6 6-3 6-4.

The 22-year-old won 73 per cent (22/30) of his second-serve points and saved six of the seven break points he faced as he moved to 16-12 for the season.

In the battle of the British players, Cameron Norrie beat Jack Draper 6-3 6-3, while Denis Shapovalov was leading Frances Tiafoe 6-3 when their match was suspended due to fading light. They will resume on Saturday.

At the Halle Open, Andrey Rublev reached his sixth ATP Tour semi-final of the year thanks to a 7-6 (7-4) 6-2 win over 2011 champion Philipp Kohlschreiber.

"I am happy with my performance to reach the semi-finals for the first time," Rublev said. "The first set was really tough. He was 3-0 up in the tie-break and I came back, which was the key.

"After the first set, I think he mentally went down and I was pumped up. I hit a couple of good returns in the first game of the second set."

Russian Rublev will face Nikoloz Basilashvili in the last four after the Georgian defeated Lloyd Harris 6-4 7-6 (7-5). 

In the day's other quarter-finals, Felix Auger-Aliassime beat Marcos Giron 6-3 6-2 and Ugo Humbert overcame Sebastian Korda 6-2 6-7 (5-7) 6-4.

Dominic Thiem has joined Rafael Nadal in announcing he will not compete at the Olympic Games in Tokyo.

The 27-year-old US Open champion pinned his decision on the belief he would struggle to find his best form, having endured a tough 2021 season so far.

Thiem has lost his last three matches, including a first-round defeat to Pablo Andujar at the French Open, and has an overall 9-8 win-loss record for the year.

World number five Thiem confirmed, however, that he intends to play Wimbledon, which begins on June 28, and will then focus on getting in the best possible shape for his grand slam title defence at Flushing Meadows.

Nadal said earlier on Thursday that he would play neither Wimbledon nor the Olympics, where the tennis tournament starts on July 24, because he wished to recover from his clay-court season efforts.

Women's tour superstar Naomi Osaka has elected to miss Wimbledon but said on Thursday she would represent Japan at her home Olympics.

Thiem revealed his Olympics decision in a statement posted on his Twitter page, saying: "After talking with my team and analysing the situation I have taken the very difficult decision to withdraw from competing in the Tokyo Olympics.

"For me, like all athletes, taking part in the Olympics and representing my country is a huge honour and that makes this decision even tougher. However, 2021 did not start as expected and I don't feel ready to play my best in Tokyo.

"These last two weeks I have been training hard – and I’m starting to improve my conditioning and concentration little by little. My goal is to work hard the coming weeks, give my best at Wimbledon and keep training and hopefully defend my US Open title.

"I wish the entire Austrian team traveling to Tokyo all the best. I am young and I hope to be able to play for Austria at the Olympics in Paris 2024."

Top seed Matteo Berrettini beat Andy Murray to reach the quarter-finals at Queen's Club and Ugo Humbert upset Alexander Zverev at the Halle Open on Thursday.

Murray, a five-time champion at Queen's, was beaten 6-3 6-3 by Italian Berrettini as the three-time grand slam champion struggled a day on from being given a Wimbledon wildcard.

The former world number one beat Benoit Paire in his first ATP Tour singles match since March on Tuesday, but the 34-year-old revealed he is still being troubled by a groin injury after his loss to Berrettini and knows he must raise his game.

Murray said: "I actually felt my movement was actually quite good for both of the matches. My tennis today was not very good. That's the thing that I'll need to improve the most.

"Then there is still a slight niggle in the groin, so [I have] to try to get rid of that discomfort between now and Wimbledon. I need to be playing points, basically. I played two sets in preparation for this event.

"I do feel like I genuinely have been hitting the ball well in practice, but then like today when you're under a bit more pressure and stuff and you're having to make very split-second decisions when you're on the court, if the guy is serving 140 miles an hour, like, it's difficult to prepare for that."

Dan Evans made history earlier in the day, getting the better of Adrian Mannarino 6-4 7-6 (9-7).

With Jack Draper and Cameron Norrie having already progressed, Evans' win ensured there will be three Britons in the singles quarter-finals for the first time in the Open Era.

Feliciano Lopez will not retain his title in London after the Spaniard went down 6-2 6-3 to second seed Denis Shapovalov. Spanish veteran Lopez won in 2019, with last year's tournament cancelled due to the pandemic.

There will be no glory on home soil in Halle for German Zverev, who was taken out 7-6 (7-4) 3-6 6-3 by unseeded Frenchman Humbert.

Humbert has now beaten a top-10 player on every surface, with Zverev serving 20 aces but bowing out after his 22-year-old opponent claimed the only break of the final set.

Sebastian Korda battled past Kei Nishikori 2-6 6-3 7-5 in Halle, while Lloyd Harris also moved into the last eight at Lukas Lacko's expense.

The US Open is set to be the first tennis grand slam to operate at full spectator capacity for its duration since COVID-19 became a global crisis.

Tournament organisers said on Thursday that the major, which was played behind closed doors in 2020, would not impose reduce attendance measures this year.

"New York is back, and so are the fans," a statement on the tournament's website said. "The 2021 US Open will welcome fans back to the USTA Billie Jean King National Tennis Center at 100 per cent capacity for the two-week tournament."

Mike Dowse, chief executive of the United States Tennis Association (USTA), said: "We are extremely excited to be able to welcome our incredible fans back to the US Open this year.

"While we were proud that we were able to hold the event in 2020, we missed having our fans on-site, because we know that they are a large part of what makes the US Open experience unlike any other.

"Indeed, the challenges presented by the pandemic were tough on us all, but our sport came together like never before and tackled each challenge head on."

Dowse added: "Our sport surged in the toughest of times, and this year's US Open promises to be an unforgettable celebration of the game, those who play it, and those who revel in it."

The tournament added that it would follow all COVID-related guidelines, although its intention clearly is to run the major in as normal a manner as is possible.

The US Open's announcement came on the day tickets went on sale for the upcoming Wimbledon championship, which begins on June 28. The grass-court slam was cancelled last year.

Wimbledon will operate at a 50 per cent attendance restriction for much of its duration, although the weekend of the finals is due to see Centre Court at 100 per cent capacity.

The French Open functioned with a vastly reduced number of tickets available in both its 2020 and 2021 editions, compared to previous years.

The Australian Open in February capped spectator numbers at 30,000, although a snap lockdown in Melbourne meant there were no crowds for five days midway through the event, with Rod Laver Arena then limited to approximately 50 per cent capacity for the closing stretch of the event.

Naomi Osaka and Dominic Thiem won the women's and men's singles titles at the 2020 US Open, and this year's tournament runs from August 30 to September 12.
