Daniil Medvedev set up a second-round showdown with home favourite Dominic Thiem at the Vienna Open after defeating Nikoloz Basilashvili in straight sets on Wednesday.

The top seed broke early and late in both sets as he cruised through the opening round a 6-2 6-2 winner.

Next up for Medvedev is a clash with former US Open champion Thiem, who beat him in the semi-finals on the way to triumphing at Flushing Meadows two years ago.

Stefanos Tsitsipas overcame local wildcard Dennis Novak 7-6 (7-2) 6-2 as the Greek ace seeks a third final in as many weeks, having lifted the title in Astana and finished as runner-up to Holger Rune in Stockholm.

Jannik Sinner also advanced in straight sets against Cristian Garin, but Taylor Fritz's ATP Finals hopes suffered a blow after the fourth seed was beaten 6-1 4-6 6-3 by Denis Shapovalov.

Over in Basel, world number one Carlos Alcaraz sailed through to his 11th quarter-final of the season after a commanding 6-4 6-2 win over Botic van de Zandschulp.

Meanwhile, Felix Auger-Aliassime recovered from losing the opening set to deny Marc-Andrea Huesler. The third seed claimed a career-best ninth successive ATP Tour victory, as he looks to complete a hat-trick of titles in as many weeks having recently reigned in Florence and Antwerp.

Stockholm champion Rune built on his recent momentum with a 6-2 7-5 success over Alex de Minaur, but Naples winner Lorenzo Musetti was ousted in a deciding set by Albert Ramos-Vinolas. 

Carlos Alcaraz reached the last-16 stage of the Swiss Indoors Basel by beating Jack Draper in three sets on Monday.

The number one seed lost the opening set but responded to take the following two and win 3-6 6-2 7-5.

Alcaraz dominated at the net, winning 30 of 39 points to edge out his opponent after more than two hours.

Elsewhere, at the Vienna Open, fourth seed Taylor Fritz overcame Yoshihito Nishioka in another three-set thriller.

Nishioka took the opener, and Fritz was staring down the barrel in a second-set tie-break before trailing by a break in the decider.

However, the American won the final five games to advance 6-7 (4-7) 7-6 (9-7) 6-3.

The comeback boosted Fritz's chances of making the ATP Finals, trailing Felix Auger-Aliassime by 315 points in the Race to Turin.

Third seed Andrey Rublev found life far easier as he beat Diego Schwartzman 6-4 6-1.

Carlos Alcaraz was dumped out of the Astana Open in the first round on Tuesday, suffering a surprise 7-5 6-3 defeat to David Goffin.

Goffin entered the draw as a lucky loser after squandering two match points to lose his final qualification match against Luca Nardi on Sunday, but he produced a fine display to see off the world number one in one hour and 46 minutes. 

The Belgian had to rediscover his composure to take the opener after throwing away a 5-2 lead, but ultimately deserved his straight-sets win over the US Open champion. 

Speaking on court after his victory, Goffin said: "I always believe that I have the level to cause some trouble against those guys. 

"When you play against the world number one on a big stage, big crowd, the fire inside gives you so much power to play your best tennis because you don't have any choice."

Stefanos Tsitsipas was the only other seed in action in Kazakhstan on Tuesday, and he advanced to the round of 16 by beating home favourite Mikhail Kukushkin 6-3 6-4.

The Tokyo Open also lost its top seed, as Casper Ruud fell to a 6-3 6-3 loss to Jaume Munar, who claimed his first top-10 win since beating Alexander Zverev in 2019.

But the likes of Borna Coric and Nick Kyrgios fared better, claiming straight-sets wins over Thanasi Kokkinakis and Tseng Chun-hsin, respectively.

Wimbledon runner-up Kyrgios only dropped four further points on his serve after being forced to save a break point in his opening service game, racing to a dominant 6-3 6-1 win.

Elsewhere, eighth seed Dan Evans fought back to beat Radu Albot 6-7 (3-7) 6-1 6-4, and Alex de Minaur lost 6-3 6-2 to Kwon Soon-woo. 

Novak Djokovic does not regret missing out on the US Open due to his vaccination stance and is waiting to discover if he will be allowed to compete in the 2022 Australian Open.

The 21-time grand slam winner missed two of this year's four majors owing to his decision to not be vaccinated against COVID-19.

Though Djokovic was able to extend his record at Wimbledon, he lost joint control of the outright Open Era title for most men's single majors to Rafael Nadal, after the latter won in Australia and then at the French Open.

Carlos Alcaraz, meanwhile, won a maiden grand slam to become the new world number one with victory at Flushing Meadows earlier this month.

Djokovic was barred from entering the USA on vaccination grounds, but speaking ahead of this week's Laver Cup, the Serbian says he does not rue his choice.

"No, I don't have any regrets," he said. "I mean, I do feel sad that I wasn't able to play but that was a decision that I made, and I knew what the consequences would be. I accepted them and that's it."

Djokovic was quick to hail teenager Alcaraz, congratulating the Spaniard for his victory, and adding: "He did it in an incredible fashion. He's 19 years old and already the number one in the world.

"I think he's a great addition to our sport, a great star in the making. We can't speak about him as the future because he is already the present."

Djokovic's 2022 started in less than auspicious circumstances when, having been granted an exception to compete in Australia despite the nation's strict COVID-19 protocols, he was subsequently deported.

Questions over whether he would even be allowed back in the country remain up in the air, but the Serbian is hopeful of a reprieve.

"I'm waiting for the news," he added. "It's really not in my hands right now. So I'm hoping I can get some positive news soon."

Carlos Alcaraz fell to a defeat to fellow youngster Felix Auger-Aliassime in his first match as world number one.

Alcaraz triumphed at the US Open on Sunday, beating Casper Ruud to clinch his first grand slam title and, in the process, become the youngest world number one since the rankings were first published in 1973.

The 19-year-old is the second-youngest male player to win the title at Flushing Meadows in the Open Era, and only the third player since the majors welcomed professionals in 1968 to win the US Open title at his first or second main draw appearance after Arthur Ashe and Rod Laver (in the first two editions of the tournament).

Yet back on home soil in Spain on Friday, Alcaraz was unable to claim victory in his first match since becoming number one, as he went down 6-7 (3-7) 6-4 6-2 to Auger-Aliassime in the Davis Cup Finals.

Canada's Auger-Aliassime did not concede a break point as he dragged his country level in their tie with Spain in Valencia, teeing up a doubles decider after Roberto Bautista Agut defeated Vasek Pospisil 3-6 6-3 6-3.

Auger-Aliassime, 22, has won both of his career matches against Alcaraz, after defeating him in the US Open quarter-finals last year.

US Open champions past and present Andy Roddick and Carlos Alcaraz led a swathe of social media tributes to Roger Federer after the 20-time grand slam winner announced his retirement.

Federer, who has not played competitively since exiting Wimbledon at the quarter-final stage last year, revealed on Thursday that next week's Laver Cup will be his farewell tournament.

Federer appeared at a parade of former champions at Wimbledon earlier this year and hinted at his desire to feature at the All England Club once more, but his upcoming outing in London will now represent the swansong to his stunning career.

The Swiss great will become the first of the ATP Tour's 'Big Three' to exit the sport, with Rafael Nadal and Novak Djokovic still active. 

While Nadal and Djokovic have each surpassed Federer's tally of 20 major titles this year, the 41-year-old overtook Pete Sampras' previous record of 14 grand slam titles by beating Roddick in the 2009 Wimbledon final.

Roddick was among the first to pay tribute to Federer's achievements on Thursday, writing on Twitter: "Cheers Roger. Thanks for the shared memories my friend. 

"It was an honour to share time/experiences on the most hallowed grounds in our sport. Don't be a stranger."

Alcaraz, who clinched his first grand slam title and became world number one with a US Open final win over Casper Ruud on Sunday, simply wrote: "Roger…", accompanied by a heartbroken emoji.

Milos Raonic has seen his efforts to win a major title foiled by the presence of the 'Big Four' – with Andy Murray beating him on his sole grand slam final appearance at Wimbledon in 2016 – but he also showed his appreciation for Federer's impact.

"Thank you for doing more for tennis than any single individual," Raonic wrote. "Thanks to you competitors and fans across the world get to experience and enjoy it all over the world. 

"Congratulations on your achievements and the people you continue to impact in and away from tennis."

Juan Martin del Potro, who prevented Federer from winning six consecutive US Open titles with a five-set success in the 2009 final, labelled the 41-year-old irreplaceable, declaring: "I LOVE YOU, Roger. 

"Thank you for everything you've done in tennis and with myself. [The] tennis world will never be the same without you."

Former player-turned presenter James Blake added: "Roger, there was and never will be anyone like you. You crushed me on the court, but were so nice and genuine that I couldn't hate you for it. 

"You made the game better on and off the court and you will be missed. Good luck, you have earned all the success and joy in the world."

Garbine Muguruza tweeted: "RF" followed by a heartbroken emoji.

Those who shared a court with Federer were not the only ones to pay tribute, however.

A tweet from Wimbledon's official account read: "Roger, where do we begin? It's been a privilege to witness your journey and see you become a champion in every sense of the word. We will so miss the sight of you gracing our courts, but all we can say for now is thank you, for the memories and joy you have given to so many."

Roland Garros' official account tweeted: "An inspiration on and off the court. Thank you, Roger."

The US Open's handle simply posted: "Thank you, Roger."

Victory at Flushing Meadows on Sunday night saw Carlos Alcaraz anointed both the US Open champion and the new world number one.

The victor of the New York final between Alcaraz and Casper Ruud would climb to the top of the ATP rankings, and a four-set success for the 19-year-old made him the youngest ever men's number one.

That record had previously belonged to a 20-year-old Lleyton Hewitt in November 2000.

Although Alcaraz's huge potential has long been public knowledge, the chances of him beating Hewitt's mark still seemed remote when he started 2022 ranked 32nd.

Even Juan Carlos Ferrero, the Spaniard's coach, did not anticipate a major breakthrough this soon, telling reporters after Sunday's win: "Of course, it comes very fast.

"It's a surprise for everybody except maybe to me, because I trained with him every day and I know [how] he's able to play on the court, [but] I was pretty sure that maybe it wasn't this year; it could be the next one."

By the time he took to Arthur Ashe Stadium against Ruud, however, Alcaraz's ascent to the top of the sport was a surprise to nobody.

Moving from number four to first place might have tied the biggest leap to number one in rankings history, but Alcaraz leads the ATP Tour in both match wins (51) and titles (five) in 2022.

There is little prospect of him slowing now, having become the first man in the Open Era to win the US Open title as early as in his second entry; the last to do so in any era was Pancho Gonzales back in 1948.

"Of course, I'm hungry for more," Alcaraz said afterwards. "I want to be in the top for many, many weeks. Hopefully many years.

"I'm going to work hard again after this week, this amazing two weeks. I'm going to fight to have more of this."

And Alcaraz will have to fight – Ferrero knows as much as that.

"The players now are going to play very motivated against him," the teenager's coach added. "Now he's number one. Before he was two or three.

"Even like this, it's like Real Madrid-Barcelona, there's a rivalry that gets you [to] increase your level. It's what is going to happen to him against his opponents. He has to be ready."

Since Roger Federer became the 23rd different men's number one in February 2004, the rankings have been dominated by the 'Big Three', with only Andy Murray and then, this year, Daniil Medvedev also leading the Tour in that time.

Now, as the 28th number one, Alcaraz – compared by Ruud to each of Federer, Rafael Nadal and Novak Djokovic – can set about securing his own long stay at the summit.

Carlos Alcaraz has a mixture of the qualities Rafael Nadal and Novak Djokovic possess, according to the man he defeated in the men's US Open final Casper Ruud.

Prodigious Spanish talent Alcaraz became a grand slam champion for the first time at the age of just 19 thanks to a 6-4 2-6 7-6 (7-1) 6-3 triumph at Arthur Ashe Stadium on Sunday.

It was a win that propelled him to the top of the world rankings for the first time, while Ruud has now lost two slam finals this year having been defeated by Nadal at the French Open.

Ruud was philosophical about losing to a player many believe will be the dominant force in the men's game, likening his movement on the court to legends Nadal and Djokovic.

"When someone asks about a player's biggest weapon you tend to think forehand, backhand, serve, whatever it is," Ruud said.

"But sort of his movement is one of his many weapons. It makes us other players feel like you need to paint the lines sort of to be able to hit a winner. Sometimes even that's not enough.

"He's very fast. He's very quick. He's a great mover. He can get to balls that we've probably never seen before.

"But you have other great movers, as well. I mean, this game has become so physically demanding, and all the players in the top of the world, they do the right things to improve always.

"Speed, agility of the players I think are just improving, improving. The physical aspect has been not changed but it has improved by everyone.

"I think Novak and Rafa and also [Roger] Federer, I think they kind of set the bar on how well you can move out there. 

"Rafa, when he was Carlos' age, he was also similar. He tracked down everything. Almost no one could hit a winner on him. Novak the same with his flexibility. He gets to certain shots that you think, 'how is that even possible?'

"Carlos has sort of a mixture of both. He's fast, flexible. He can slide around. It's impressive. He's a hard nut to crack."

Ruud can take consolation from the fact his second appearance at a slam final was a marked improvement on Roland Garros where Nadal breezed to a 6-3 6-3 6-0 triumph.

The Norwegian conceded he had more belief going up against Alcaraz in New York, though he – somewhat tongue-in-cheek – added he hopes not to play a Spaniard in any future slam finals.

"I think obviously if you reach a grand slam final, whoever you play will be a great player on the opposite side of the net," he added.

"At Roland Garros, it was hard for me to believe that I could beat Rafa. Today was not easier, but I believed it more. I think these two tournaments have sort of made my self-belief to win a grand slam grow.

"Hopefully these two experiences can help me. I guess I hope I don't play a Spanish player if I ever reach another slam final! They know what they're doing in the slam finals. Let's hope for another than a Spanish [player]."

Ruud added: "I still thought I was the underdog in a way because of Carlos, he's on paper higher ranking and all these things. 

"But it was more fun for me today. I didn't need to play the biggest idol of my life on the biggest match of my life. It was sort of easier for me to believe that I could win."

Carlos Alcaraz never thought his success would come as quickly as it has, with the 19-year-old becoming the youngest men's world number one in history by defeating Casper Ruud in the US Open final on Sunday.

It was Alcaraz's first grand slam final, and in the process he broke the record for the most cumulative court time at a single grand slam after grinding through three consecutive five-set matches in the lead-up to the four-set final.

This is the third big tournament the Spaniard has won this year. He became the first player born after the year 2000 to win an ATP 1000 Masters event when he beat Ruud at the Miami Open, and then followed it up with a straight-sets win over Alexander Zverev in the Madrid Open final.

Speaking to the media after his maiden major title, Alcaraz called it "crazy" and a "dream".

"Well, it's crazy for me," he said. "I never thought that I was going to achieve something like that at 19 years old – everything has come so fast.

"For me it's unbelievable. It's something I've dreamed since I was a kid, since I started playing tennis. Of course, lifting this trophy today is amazing for me.

"Right now I'm enjoying the moment – I'm enjoying having the trophy in my hands – but, of course, I'm hungry for more. 

"I want to be at the top for many, many weeks – hopefully many years. I'm going to work hard again after this… I'm going to fight for more of this."

With his rapid rise to the pinnacle of the sport, Alcaraz said his victory in Miami was when he realised the path he was on could include grand slam titles.

"Honestly, since I won Miami," he said. "Since I won Miami, I thought I was able to have a grand slam in my hands.

"But before Miami, I was thinking that I have to still grow up. I thought that I'm able to have good results in a grand slam, but not a champion.

"But I would say after Miami – I won great matches in a row – I would say after that I thought that I'm able to win a grand slam."

Casper Ruud was understandably disappointed to miss out on the US Open title and the world number one spot, but he vowed to continue his pursuit of a major breakthrough.

Ruud played his second grand slam final of the season at Flushing Meadows on Sunday, yet that match ended in the same manner as his French Open defeat to Rafael Nadal.

The Norwegian, who would have led the rankings had he taken the title, went down 6-4 2-6 7-6 (7-1) 6-3 to Carlos Alcaraz, who instead himself became the youngest ever number one.

It was the first major final played between two men looking to become number one for the first time.

Ruud was bidding to make the biggest leap to the top of the rankings, having previously been the world number seven.

It was not to be, but the 23-year-old's reward for his form in New York was number two – a fine consolation prize.

"It's tough to explain everything," Ruud said, reflecting on his season. "Things have been going so well. I'm so excited for it.

"Today was a special evening. Both Carlos and I knew what we were playing for, we knew what was at stake.

"It's fun that both finalists would be number two and number one tomorrow. I think it's fitting.

"I'm disappointed, of course, that I'm not number one, but number two is not too bad either. I will continue to chase for my first grand slam and the number one ranking."

Carlos Alcaraz was determined fatigue would not get the better of his US Open title tilt, but he accepted he was "a little bit" tired after defeating Casper Ruud in Sunday's final.

Alcaraz set a grand slam record for the most time spent on court at a single tournament, in large part due to playing five-set matches in the fourth round, quarter-finals and semi-finals.

Still, the 19-year-old had enough energy left to take down Ruud in four sets, with his 6-4 2-6 7-6 (7-1) 6-3 victory making him a first-time major champion and the new world number one.

Asked if he would now acknowledge the effects of this run on him, Alcaraz replied: "A little bit.

"I always say it's not time to be tired in the final round of a grand slam or any tournament; you have to give everything on court, everything you have inside. It's something I work really, really hard on."

Alcaraz is the youngest player to ever sit atop the men's rankings, and he added: "This is something I dreamt of since I was a kid, to be number one in the world, to be a champion of a grand slam.

"It's something I worked really, really hard for. It's tough to talk right now. There's a lot of emotions right now.

"This is something I tried to achieve. All the hard work I did with my team, my family... I'm just 19 years old, so all the tough decisions are with my parents, my team as well. This is something that is really, really special for me."

Carlos Alcaraz defeated Casper Ruud in four sets to win his first major at the US Open and make history in moving to the top of the ATP rankings.

Either Alcaraz or Ruud would have taken the world number one spot had they won at Flushing Meadows, and it was the 19-year-old who prevailed 6-4 2-6 7-6 (7-1) 6-3 on Sunday.

The teenager – the second-youngest New York champion of the Open Era after Pete Sampras – therefore became the youngest ever men's number one.

Alcaraz had come through five-set matches in each of the prior three rounds, and he was again worked hard by Ruud – the new number two.

Ultimately, though, the highly talented Spaniard had the staying power to win his first grand slam title, becoming the first teenager to do so since Rafael Nadal at the 2005 French Open.

Despite the draining efforts of previous nights, Alcaraz made a rapid start, quickly forging three break points in the third game of the match and taking the second of them.

Ruud did little else wrong in the first set but had to bide his time to respond, losing the opener and fending off an opportunity for a break in the second before immediately applying pressure going the other way.

The Norwegian reached an Alcaraz drop shot and lobbed his opponent before watching the backhand reply land long to lead, although three unforced errors in the next game almost let Alcaraz back in.

Instead, Ruud dug in and then profited when a sloppy Alcaraz service game allowed him to clinch the second set.

Alcaraz responded in sublime fashion, immediately piling on the pressure in the third frame and breaking down Ruud's defence with a pinpoint drop shot, yet the set was level again when he crashed into the net, with a sensational rally required to reach a tie-break.

A couple of wild Ruud strokes decided the 73-minute set in Alcaraz's favour, though, and the fifth seed went long in the fourth to set his opponent on course, with an emotional victory secured in ruthless style.

Data Slam: Marathon man Carlos crowned in New York

Only the third player to reach the US Open final after winning in five sets in each of the prior three rounds, Alcaraz avoided seeing another match going all the way – even if past results suggest that would have worked in his favour.

Regardless, Alcaraz set a new record for the most time spent on court at a major tournament. Since 1999, when this data was first available, Kevin Anderson's 2018 Wimbledon run had previously represented the benchmark.

Carlos Alcaraz will "give everything" to win the US Open and become world number one as he prepares to face Casper Ruud in Sunday's final.

Alcaraz overcame home favourite Frances Tiafoe in a thrilling five-set semi-final at Flushing Meadows on Friday, winning 6-7 (6-8) 6-3 6-1 6-7 (5-7) 6-3.

The 19-year-old will take on Ruud for the title after the Norwegian beat Karen Khachanov in four sets earlier in the day.

The honour of becoming world number one will also be on the line for both, after current holder Daniil Medvedev was eliminated in the round of 16 by Nick Kyrgios.

Speaking on-court after his victory against a spirited Tiafoe, Alcaraz said: "To be honest in the semi-final of a grand slam you have to give everything. 

"We have to fight until the last ball. It doesn't matter if we are fighting for five hours, six hours. It doesn't matter. You have to give everything on court. Frances gave everything on court. This is amazing."

The winner of Sunday's final will seal his first career grand slam, while Alcaraz will create history if he wins as it will make him the youngest world number one since the ATP rankings began in 1973.

It will be the Spaniard's first grand slam final, while his opponent appeared in a losing effort to Rafael Nadal in June's French Open final.

Alcaraz will need to recover from his third consecutive five-set match at the US Open, but insisted he will "give everything" to win.

"It's amazing to be able to fight for big things. First time in the final of a grand slam. I can see the number one in the world, but at the same time it's so far away," Alcaraz added.

"I have one more to go against a player who is unbelievable. He deserves to play a final. He played the final of a grand slam in Roland Garros. This is my first time. 

"I'm going to give everything that I have. I will have to handle the nerves of being in a final of a grand slam, but obviously I'm really, really happy and as I said before every match, I'm going to enjoy the moment."

Frances Tiafoe insisted he will return and win the US Open "one day" after coming up short in an enthralling five-set semi-final against Carlos Alcaraz.

The home favourite won the first and fourth sets on tie breaks, only to lose the decider as his 19-year-old opponent sealed a 6-7 (6-8) 6-3 6-1 6-7 (5-7) 6-3 victory on Friday.

Tiafoe was emotional after his loss as an appreciative crowd at Flushing Meadows acknowledged his efforts.

"I gave everything I had," he said during his on-court interview. "Too good from Carlos tonight.

"I gave everything I had for the last two weeks. I came here wanting to win the US Open and I feel I let you guys down."

The 24-year-old had an impressive run in the tournament, beating higher seeds Diego Schwartzman, Rafael Nadal and Andrey Rublev to reach the final four.

"This one hurts. This one really, really hurts," he added. "Too good from Carlos, you're gonna win a lot of grand slams, you're a hell of a player, hell of a person.

"I'm happy I got to share the court and such a big stage with you. 

"I'm going to come back and I will win this thing one day. I'm sorry guys."

Alcaraz will face Casper Ruud in Sunday's final after the Norwegian beat Karen Khachanov in four sets in Friday's other semi-final.
