Teenage sensation Carlos Alcaraz put in an impressive display to upstage eighth seed Jannik Sinner in straights sets in the third round of the ATP Paris Masters on Wednesday.

Alcaraz was on top for most of his 7-6 (7-1) 7-5 victory, winning 80 per cent of his first-serve points and 75 per cent of net points against Sinner.

Sinner showed determination to stay in both sets, with the Italian saving nine of the 11 break points he faced, but it was ultimately in vain.

The European Open winner will be among those sweating as the race to qualify for the ATP Finals in Turin heats up.

After the win, 18-year-old Alcaraz said: "I'm so happy for this win as Jannik was fighting for a spot at the ATP Finals. It's my third Top 10 win of the year.

"I think Jannik and I will have a great rivalry in the future... I think that I played really, really aggressive, more than him. I think that was one of the keys."

Alcaraz will now face qualifier Hugo Gaston in the next round after the Frenchman impressively knocked out 12th seed Pablo Carreno Busta 6-7 (3-7) 6-4 7-5.

Interesting day for Turin hopefuls

It was a mixed day for others looking to secure a spot at the season-ending ATP Finals later this month as Felix Auger-Aliassime – ranked 12th in the ATP Race to Turin – lost in straight sets to Dominik Koepfer, who added to his impressive list of victims after beating three-time grand slam champion Andy Murray in the first round.

Koepfer will play another Turin hopeful, the 10th-ranked Hubert Hurkacz after he beat Tommy Paul in straight sets.

Cameron Norrie also impressed in his 6-3 6-4 win over Reilly Opelka, which was his 50th tour-level win of the year.

Taylor Fritz awaits after the American stunned fifth seed Andrey Rublev 7-5 7-6 (7-2).

Medvedev and Zverev ease through but Tsitsipas out

Second seed and US Open champion Daniil Medvedev had a routine first match of the tournament as he swept past Ilya Ivashka 7-5 6-4, while Olympic Games gold medallist and fourth seed Alexander Zverev also had few problems against Dusan Lajovic 6-3 7-6 (7-5).

However, third seed Stefanos Tsitsipas exited after retiring hurt with an apparent arm injury against Alexei Popyrin in the first set with the score at 4-2 to the Australian.

Popyrin will now face fellow countryman James Duckworth, who followed up his impressive win against 14th seed Roberto Bautista Agut with a 6-3 3-6 6-3 victory against Lorenzo Musetti.

Elsewhere, 11th seed Diego Schwartzman was shocked by qualifier Marcos Giron 7-6 (7-2) 7-6 (7-4).

There were also wins for 16th seed Grigor Dimitrov against Karen Kachanov, and Sebastian Korda over Marin Cilic.

Gael Monfils will go up against world number one Novak Djokovic in the third round after the experienced French 15th seed came from behind to beat compatriot Adrian Mannarino 2-6 7-6 (7-4) 6-2.

Top seed Andrey Rublev crashed out of the St Petersburg Open after a straight-sets defeat by Dutch qualifier Botic van de Zandschulp in the quarter-finals.

A recent US Open quarter-finalist, world number 69 Van de Zandschlup claimed the first top-10 win of his career on Friday.

The 26-year-old also advanced to the semi-finals of an ATP event for the first time.

There, he will face 2011 champion Marin Cilic, who was a 6-4 3-6 6-3 winner over third seed Roberto Bautista Agut.

Denis Shapovalov was another big-name casualty in Russia, the second seed going down 4-6 3-6 against world number 53 Jan-Lennard Struff.

Although, there were better fortunes for fifth seed Taylor Fritz. The Indian Wells semi-finalist is yet to drop a set this week after prevailing 6-4 6-2 against John Millman.

Elsewhere, Matteo Berrettini was the victim of another upset at the Erste Bank Open in Vienna.

The Wimbledon champion went down 1-6 7-6 (7-2) 6-7 (5-7) following a two-hour 40-minute battle with Carlos Alcaraz.

Reaching his first ATP 500 semi-final, the Spanish teenager claimed another big scalp having defeated Stefanos Tsitsipas at Flushing Meadows last month.

However, second seed Alexander Zverev remained on course for a fifth title of the season, as he claimed his 300th tour-level win.

The Australian Open finalist beat Felix Auger-Aliassime 6-4 3-6 6-3, avenging his fourth-round defeat by the Canadian at Wimbledon in July.

Alexander Zverev and Jannik Sinner moved into the quarter-finals of the Vienna Open on Thursday. 

Italian Sinner beat home hopeful Dennis Novak 6-4 6-2 to set up a tantalising showdown with Casper Ruud. 

Should he win that match, Sinner will move ahead of Hubert Hurkacz in the race to qualify for this year's ATP Finals, while victory for Ruud will strengthen the Norwegian's standing. 

"It's going to be tricky," said Sinner. "He's in a better position than I am for the race. I think right now it's tough to say and tough to do because in the end you try always not to think about that, but in the end you think about that because you believe." 

Zverev was given a sterner test, eventually overcoming Alex de Minaur 6-2 3-6 6-2 in one hour and 42 minutes. The Olympic gold medallist will now face Felix Auger-Aliassime, who fought back from a set down to defeat Cameron Norrie. 

Frances Tiafoe came from a set down to upset top seed Stefanos Tsitsipas 3-6 6-3 6-4 and earn a quarter-final meeting with Diego Schwartzman after the Argentine overcame Gael Monfils 7-6 (7-5) 4-6 6-2. 

In St Petersburg, home favourite and sixth seed Karen Khachanov lost a gruelling three-set encounter to Marin Cilic. 

The Croatian, who won the title in Russia in his last appearance in 2011, was 4-1 down in the deciding set but took all five of the final games to triumph after two and a half hours on court. 

"Everybody is playing good. The tournament is great. It's the end of the season, so everybody wants to finish on a great level," said Cilic, who next faces Roberto Bautista Agut. "For me, it was great to play this kind of a match today." 

Another Russian, Aslan Karatsev, fell to John Millman 6-3 6-2. Taylor Fritz and Botic van de Zandschulp also progressed in straight sets. 

Stefanos Tsitsipas survived a minor scare in the first round of the Vienna Open before ultimately going on to beat Grigor Dimitrov in straight sets.

It was neck-and-neck for much of the first set, with neither player losing serve, but Dimitrov appeared to have the upper hand when he got to 6-3 in the tiebreak.

Tsitsipas recovered emphatically, however, the top seed reeling off five successive points to win the set and he went on to book his spot in the second round thanks to a 7-6 (8-6) 6-4 victory. He will face Frances Tiafoe next.

"Grigor is a tough competitor and the level of tennis was really high today. We both competed at our highest [level]," Tsitsipas said afterwards.

"That was great tennis that was being played during the entire match and I got really close to my [best] offence and showed incredible attitude [in] the last game, which was the one that was the most crucial of the match."

Alexander Zverev, seeded second, was also made to work in his first-round clash with Filip Krajinovic.

While he blew the Serbian away in the first set, he found himself 5-2 down in the second as Krajinovic looked set to level the match, but Zverev scrapped his way back and then served to love to win 6-2 7-5. Alex de Minaur awaits the German.

Casper Ruud and Felix Auger-Aliassime, seeded fourth and sixth respectively, were two other high-ranking players who also secured progression, boosting their ATP Finals qualification hopes.

Ruud was pushed hard by Lloyd Harris but eventually outfought the South African in his 7-5 7-6 (7-2) win, while Auger-Alisassime made fairly light work of Ricardas Berankis 6-3 6-2.

Indian Wells champion Cameron Norrie, who is also in with a shot of reaching the ATP Finals, beat Marton Fucsovics 7-6 (7-4) 6-1 to set up a meeting with Auger-Aliassime – the British number one is 11th in the FedEx ATP Race to Turin rankings, one above his next opponent.

At the St Petersburg Open, fifth-seed Taylor Fritz was the highest-ranked player in action and he needed a little over an hour to beat Emil Ruusuvuori 6-1 6-4.

Pablo Andujar defeated Federico Delbonis to set up a meeting with second seed Denis Shapovalov, while Ilya Ivashka beat Laslo Djere for the right to tussle with tournament favourite Andrey Rublev next.

Alexander Zverev rued a missed opportunity to win the Indian Wells Masters as he crashed out in the quarter-finals at the hands of home favourite Taylor Fritz.

American Fritz saved two match points to pull off an upset 4-6 6-4 7-6 (7-3) win over Olympic gold medallist Zverev.

Third seed Zverev was aware he had become hot favourite to triumph in California after Stefanos Tsitsipas crashed out to Nikoloz Basilashvili earlier on Friday, with US Open champion Daniil Medvedev already eliminated.

And the German was frustrated with his performance against Fritz, which left him unable to add to the Masters 1000 titles he has already won in Madrid and Cincinnati this year.

"It was just not really my day, to be honest," said Zverev, who had beaten Jenson Brooksby, Andy Murray and Gael Monfils to reach the last eight.

"I was close to winning, but the level of tennis was just not there for me.

"Mentally this is not easy for me. My next tournament is Vienna, so hoping I can deal with it well there, but right now I just want to go home.

"It was a very long season and I have played well but this one hurts because I knew that, after Stefanos lost this morning, I was kind of the favourite to win this tournament, but my tennis wasn't there yet."

Zverev had won 20 of his previous 21 matches on hard courts and led 5-2 in the deciding set.

But Fritz was not to be denied, firing 36 winners to secure the second top-five win of his career, with this triumph adding to impressive victories over Italian duo Matteo Berrettini and Jannik Sinner this week.

Fritz said: "This is the farthest I've ever been in a big tournament. 

"It is easily the best win of my life, against a really tough opponent on arguably the biggest match I could possibly play, so it's great.

"The biggest thing was match point down, I wanted to make him serve it out, so I just fought as hard as I could to hold that game.

"Then I got fortunate in his service game and from there I felt in control and felt really good under the pressure. I kept fighting. The crowd pushing me on meant so much.

"It is amazing. Especially the way that match ended with such high emotions with the crowd. The crowd was amazing and it is a dream come true."

Stefanos Tsitsipas and Alexander Zverev both crashed out in the quarter-finals on a day of upsets at the Indian Wells Masters.

Tsitsipas – the second seed – suffered a shock defeat to Nikoloz Basilashvili in a memorable outing for the Georgian in the Californian desert on Friday.

Afterwards, third seed Zverev was upstaged by Taylor Fritz in another boilover at the ATP Masters 1000 tournament.

BASILASHVILI BANISHES STEFANOS FOR MAIDEN MASTERS SF

In the biggest win of his career, 29th seed Basilashvili conquered French Open runner-up Tsitsipas 6-4 2-6 6-4.

Basilashvili's powerful groundstrokes from the baseline troubled Tsitsipas throughout as he reached his first Masters 1000 semi-final.

Prior to this year, Basilashvili had never won a main-draw match at Indian Wells in four previous appearances.

"I have played really great matches this tournament," said Basilashvili, who is the first Georgian in a Masters 1000 semi-final since Irakli Labadze in 2004. "I was not that happy with how I played today but I was happy with how I managed my stress levels.

"First time in the quarter-finals and it is a big court and Stefanos is a super tough player. I had to keep my physical levels and energy levels in a really good shape because I knew mentally I would be a little bit tight and stressed."

FRITZ SAVES MATCH POINTS TO UPSET ZVEREV

Next up for Basilashvili is 31st seed Fritz, who fended off two match points to surprise Olympic Games gold medallist Zverev 4-6 6-4 7-6 (7-3).

Fritz dropped the opening set and rallied from 5-2 down in the decider as he earned his second top-five victory of his career en route to his first Masters 1000 semi-final.

"I was really down and out but I found a way to put myself into it," Fritz said in his on-court interview. "I really wanted to make him have to close me out and I was able to get back into the match.

"Normally you would be so nervous in those situations and in the third set tie-break, but I felt so confident being aggressive, going after my game. It feels really great to play well with the pressure on."

It is the second Masters 1000 tournament of the season to feature three players in their first semi-final – Basilashvili, Fritz and Cameron Norrie – after the Miami Open.

Daniil Medvedev was ousted from the Indian Wells Masters, the US Open champion and top seed stunned by former world number three Grigor Dimitrov in a thrilling comeback.

Dimitrov had been a set and a double break down against the Russian star on Wednesday, before launching a remarkable rally for his first win over a top-two opponent since 2016.

Meanwhile, second seed Stefanos Tsitsipas and third seed Alexander Zverev both won to secure their spots in the last eight.

MEDVEDEV SHOCKED IN THE DESERT

Dimitrov roared back to triumph 4-6 6-4 6-3 over Medvedev, who had won 18 of his past 19 matches on North American soil.

Bulgarian star Dimitrov trailed 4-1 in the second set after dropping the opener before stunning the first-time grand slam champion midweek.

"I just felt something at 1-4 and I calmed myself down and started to take better decisions and started to control the pace of the game, which I really believed helped me," Dimitrov – the 23rd seed – said. "In the end it was just very solid and smart play."

Dimitrov finished the match with 25 winners, while he was also excellent at the net, helping him claim his first quarter-final appearance at an ATP Masters 1000 event this season.

Medvedev sent down 5-1 aces but only managed a 54 per cent first-serve percentage, while he also faced 10 break points across the match. Dimitrov won five games in a row to claim the second set.

"I don't remember myself losing three service games, even four service games ever, I guess, on hard courts," Medvedev said.

"That shows how slow this court is and the conditions, more like clay, I would say, which I don't like, because to lose serve four times is just unacceptable."

Dimitrov will face eighth seed Hubert Hurkacz in the quarter-finals after he got past Australian Open semi-finalist Aslan Karatsev 6-1 6-3.

Medvedev added: "Grigor played [the] second part of the match better than anybody did against me [at the] US Open that I won. Playing this level, I don't see him losing to anybody, but let's see the result."

ZVEREV MAKES STATEMENT WITH MONFILS WIN

Olympic Games gold medallist Zverev bulldozed his way past 14th seed Gael Monfils 6-1-6-3 en route to the last eight.

German star Zverev claimed his 20th win from his last 21 matches, needing just over an hour to dispatch Monfils.

Zverev claimed 19 of 25 points at the net, hitting 19 winners including 11 with his forehand, while converting four of eight break points.

"I felt well on the court today. Gael is someone I haven't beaten before, so I knew had to play my best tennis and I definitely was not far away," Zverev said during his on-court interview.

Zverev will take on American 31st seed Taylor Fritz, who defeated 10th seed Jannik Sinner 6-4 6-3.

TSITSIPAS OUTLASTS DE MINAUR

French Open runner-up Tsitsipas saw off a tough challenge from Australian Alex de Minaur to secure his spot in the quarter-finals 6-7 (3-7) 7-6 (7-3) 6-2.

Tsitsipas fought back from a set down to win against the 22nd seed, triumphing in two hours, 43 minutes.

Greek star Tsitsipas showed grit to outlast the tiring De Minaur and will face 29th seed Nikoloz Basilashvili after he knocked off fellow seed Karen Khachanov 6-4 7-6 (8-6).

"That was incredible the way I just stayed in the match," Tsitsipas said. "I had to go through so many difficulties in order to find a solution and I executed towards the end of the match."

There were further top-10 casualties, with sixth seed Casper Ruud also bowing out 6-3 6-3 to 11th seed Diego Schwartzman, who will meet Cameron Norrie in the quarters.

Alexander Zverev overcame former world number one Andy Murray to reach the Indian Wells Masters last 16 as Stefanos Tsitsipas also progressed, but Matteo Berrettini lost.

Olympic Gamed gold medallist and third seed Zverev fell behind a break in both sets but battled past Murray in straight sets at the ATP Masters 1000 tournament on Tuesday.

Tsitsipas – the second seed – rallied from a set down to vanquish Fabio Fognini in the desert, while fifth seed Berrettini was a third-round casualty.

ZVEREV CLAIMS COVETED SCALP OF MURRAY

Having already defeated Novak Djokovic, Rafael Nadal and Roger Federer in his career, all that was missing for Zverev was a win over Murray to complete the 'Big Four' sweep.

Zverev added Murray to his list of scalps with a 6-4 7-6 (7-4) victory to reach the Indian Wells fourth round for the first time since 2016.

The German star has now won 19 of his last 20 matches since Wimbledon.

"He's the only one of the Big Four that I hadn't beaten yet, so I'm happy that I've done it today," said Zverev, who will clash with 14th seed Gael Monfils in the next round. "Obviously it was a fantastic match.

"I thought Andy played extremely well, maybe as well as he's played since the surgery. I hope he continues playing the same way, because tennis did miss him for a long time and I think it's good to have him back."

TSITSIPAS FIGHTS BACK

It was far from easy for Greek star Tsitsipas, who prevailed 2-6 6-3 6-4 against 25th seed Fabio Fognini.

Tsitsipas added to his ATP Tour-leading haul of match wins this season, which now stands at 53 after Fognini had been looking to score his first victory over the French Open runner-up.

Alex de Minaur – the 22nd seed – awaits after he took down 13th seed Cristian Garin 6-4 6-2 for his first trip to the Indian Wells last 16.

BERRETTINI BUNDLED OUT

Wimbledon finalist Berrettini was no match for Taylor Fritz, who surprisingly topped the Italian 6-4 6-3.

Berrettini entered the contest as the only player on the ATP Tour this season to register double-digit wins on three surfaces – 15-4 (hard), 13-4 (clay) and 11-1 (grass).

"We're coming to the end of the year, I could really use a big result," said Fritz after claiming his first top-10 win of the year. "This is just what I needed, playing one of my favourite tournaments close to home."

Andy Murray put his body to the test as the former world number one overcame teenage sensation Carlos Alcaraz at the Indian Wells Masters, where stars Stefanos Tsitsipas and Alexander Zverev advanced to the third round.

Murray needed more than three hours to see off 18-year-old talent Alcaraz, who announced himself on the big stage with a quarter-final run at the US Open.

An Indian Wells runner-up in 2009, Murray was joined in the next round by second seed Tsitsipas and third seed Zverev on Sunday.

MURRAY WINS BATTLE OF GENERATIONS

Injuries have struck down Murray in recent years, but the three-time grand slam champion showed there is still plenty of fight left in the tank after rallying past debutant Alcaraz 5-7 6-3 6-2.

Facing a player 16 years his junior, Murray – making his 13th Indian Wells appearance – reached the third round of an ATP Masters 1000 event for the first time since 2016.

The 34-year-old Murray, who hit an underarm ace, improved his record to 27-12 in the desert following three hours, four minutes on court.

"He's obviously got so much potential, so much firepower and these conditions it's not easy to finish points off quickly, but he's able to because he has so much pace from the back of the court so I had to fight extremely hard, coming back from a set down," said Murray, who will next meet Zverev. 

"I felt like in the second set he played maybe better. First set I felt like I had more of the opportunities but didn't get it so yeah, happy with the way I fought. He's a top-drawer young player."

ZVEREV QUALIFIES FOR TURIN AS TSITSIPAS CRUISES

US Open finalist and Olympic gold medallist Zverev outlasted talented American Jenson Brooksby 6-4 3-6 6-1 to set up a showdown with Murray.

World number four Zverev ended the contest with 12 aces and 28 winners, having qualified for next month's ATP Finals in Turin thanks to the German's four tour-level titles in 2021.

"It wasn't an easy match, but I'm happy to be through, I'm happy to be in the third round and playing Andy now," said Zverev, who has won 18 of his last 19 matches since Wimbledon. "I think he's the only one of the 'Big Four' [including Novak Djokovic, Rafael Nadal and Roger Federer] I haven't beaten yet, so I hope I can change that. I think it's incredible how well he's moving and incredible how well he's playing. I think he's very motivated so I hope I can show my best tennis."

It was far more routine for Greek star Tsitsipas, who eased past Pedro Martinez 6-2 6-4 in his tournament opener.

Tsitsipas needed just 93 minutes to take down his opponent for his Tour-leading 52nd win of the season as the French Open runner-up awaits 25th seed Fabio Fognini for a place in the fourth round.

BERRETTINI ROLLS ON AS AUGER-ALIASSIME SAYS GOODBYE

Italian fifth seed Matteo Berrettini won through to the third round via a 6-4 7-5 success against qualifier Alejandro Tabilo – his first Indian Wells win following two previous appearances.

Felix Auger-Aliassime was the biggest name to depart the event on Sunday, with the seventh seed and Flushing Meadows semi-finalist going down 6-4 6-2 to Albert Ramos-Vinolas.

Jannik Sinner, Pablo Carreno Busta, Cristian Garin and Gael Monfils were among the seeds to progress.

Team Europe are poised to seal yet more Laver Cup glory after producing another dominant display against Team World, though the focus was on Nick Kyrgios following comments about his long-term future.

Europe swept Saturday's four matches in Boston to stand on the cusp of a fourth consecutive Laver Cup triumph – the defending champions lead 11-1 and require just two more points to clinch the title.

Stefanos Tsitsipas blitzed Team World's Kyrgios 6-3 6-4 at TD Garden, where Olympic Games gold medallist Alexander Zverev beat John Isner 7-6 (7-5) 6-7 (6-8) 10-5 before US Open champion Daniil Medvedev made light work of Denis Shapovalov 6-4 6-0.

Team Europe secured their fourth win of the day in the doubles – Tsitsipas and Andrey Rublev teaming up to defeat Isner and Kyrgios 6-7 (8-10) 6-3 10-4.

After Kyrgios' straight-sets loss to Greece's Tsitsipas, the 26-year-old Australian star casted doubt over his tennis future.

"This is my probably my last Laver Cup," former world number 13 Kyrgios – an Australian Open and Wimbledon quarter-finalist – told reporters post-match. "I don't know how much longer I will be in tennis.

"This is my last event of the year. I will get my body right ahead of the Australian Open.

"My mum is not doing too well with her health. I'd like to go back and see her."

"As long as I'm on the court, I will try and give my best, but I'm not going to lie and say that I'm going to plan to play four or five more years on tour," Kyrgios said. "That's just not me."

Playing for the first time since earning his maiden grand slam trophy at the expense of record-chasing Novak Djokovic at Flushing Meadows, world number two Medvedev suffered no letdown against Shapovalov.

"I played unbelievably, especially [in] the second set," Russia's Medvedev said in his on-court interview. "I didn't know what to expect because after the US Open, I didn't play for a week and a half. Came here, practised as much as I could the past three days, so I didn't hit [that] many balls, but was surprisingly feeling well.

"I wanted to show that also today. [The] first [set] was not easy, the ball was not going as fast as I wanted [and] he was playing really good. And then I just couldn't miss a ball anymore. I'm really happy about [that]."

Stefanos Tsitsipas plans to get the COVID-19 vaccine, having previously declared he would only do so if the ATP Tour made it mandatory.

Greek world number three Tsitsipas revealed last month he would not get a jab due to concerns over side effects.

The ATP Tour has persisted in encouraging players to get vaccinated, with Novak Djokovic the most high profile to have stated he was opposed to it, and Tsitsipas has now backtracked on his original stance.

"I will get vaccinated this year," the 23-year-old told Greek outlet Antenna TV. "So I can go to restaurants and shops. I support all those who get vaccinated.

"I am not a doctor; I am a tennis player, so I may not have the most substantiated opinion when it comes to medical issues."

The French Open runner-up was subject to backlash in his homeland following his initial comments on the vaccine, with a series of top figures questioning his thought process.

"The COVID-19 vaccine has not been tested enough because it is new and has some side effects," said Tsitsipas.

"I know some people who've had them. I'm not against it, I just see no reason for someone in my age group to be vaccinated [yet].

"For us young people I think it's good to pass the virus because we'll build immunity.

"I don't see it as something bad. As I said, it isn't obligatory, everyone has freedom to decide for themselves what's right and what's not. At some point we should all do it, I'm not saying the opposite.

"The time will come when we will not be given many options, but until then I want to see a better version of the vaccine that gives us more pluses than minuses."

Tsitsipas is set to play for Team Europe at the Laver Cup this week after missing Greece's Davis Cup tie with Lithuania due to a foot injury.

Carlos Alcaraz was lost for words after making history in the Spanish teenager's shock five-set upset of world number three Stefanos Tsitsipas at the US Open.

Alcaraz – rated by many as Spain's best young male player since 20-time grand slam champion Rafael Nadal first emerged – sent Tsitsipas packing 6-3 4-6 7-6 (7-2) 0-6 7-6 (7-5) in the third round on Friday.

The 18-year-old Alcaraz became the youngest player to reach the last 16 of the US Open since Americans Michael Chang and Pete Sampras in 1989.

Alcaraz also became the youngest man to beat a top-three opponent at the tournament since the ATP introduced its world ranking system in 1973.

After more than four hours on Arthur Ashe Stadium, Alcaraz told reporters: "I have not words to explain how I feeling right now.

"I just don't know what happened out there in the court. I can't believe that I beat Stefanos Tsitsipas in an epic match.

"For me it's a dream come true."

Amid comparisons with countryman Nadal, Alcaraz added: "Honestly I don't copy any style of a players. I just play my game.

"But if I have to say one player that is similar my game, I think it's [Roger] Federer. I think similar as mine game, trying to be aggressive all the time. I think it's a good similar for me."

After his US Open campaign came to a surprise end, third seed Tsitsipas tipped Alcaraz for future success.

"A hundred percent," Tsitsipas replied when asked if he had a sense of Alcaraz's potential. "I said he can be a contender for Grand Slam titles. He has the game to be there."

"I've never seen someone hit the ball so hard," French Open runner-up Tsitsipas added. "Took time to adjust. Took time to kind of develop my game around his game style.

"It's one of these matches and one of these feelings where, you know, you pick up at some point of the match, you feel like you're in control, and it doesn't really go your way at the end.

"It's kind of bitter, I would say, especially after such an incredible first set by my side, dominating, being just so aggressive, not dwelling on the past. It was a great first set.

"I don't know. I felt like he played the fifth one completely -- the way he played the first set basically, careless, going for every single shot. I have never seen someone play such a good fifth set, honestly."

Carlos Alcaraz put his name up in lights in New York as the 18-year-old stunned third seed Stefanos Tsitsipas in a massive US Open third-round upset.

Spanish teenager Alcaraz scored an astounding 6-3 4-6 7-6 (7-2) 0-6 7-6 (7-5) victory in a battle lasting four hours, seven minutes inside Arthur Ashe Stadium on Friday.

French Open runner-up Tsitsipas became the biggest casualty of the men's tournament so far as hot prospect Alcaraz showed his mettle on the grand slam stage at Flushing Meadows.

It means Alcaraz, rated by many as Spain's best young male player since Rafael Nadal first emerged, has reached the fourth round of a major for the first time in his career.

He becomes the youngest player to reach the last 16 of the US Open since Americans Michael Chang and Pete Sampras in 1989.

The US Open said the win made Alcaraz the youngest man to beat a top-three opponent at the tournament since the ATP introduced its world ranking system in 1973.

Alcaraz put a dire fourth set behind him and looked to have won the match with a lob at 6-4 in the deciding tie-break, but his ball landed a whisker long.

That meant the players were back on serve, but Alcaraz was unbowed and sealed victory with a scorching forehand winner, announcing himself as a likely superstar of the near future. He struck 61 winners in all.

He will face German qualifier Peter Gojowczyk in the fourth round, with a quarter-final place at stake.

Speaking on court after his win, Alcaraz hailed the supportive New York spectators who were firmly in his corner.

"I think without this crowd I haven't the possibility to win this match," he said. "Thank you to you the crowd for pushing me up in the fifth set

"It has been an incredible feeling for me. This victory means a lot to me. It's the best match of my career, the best win.

"For me to beat Stefanos Tsitsipas is a dream come true for me and to do it here is more special."

Men's tennis would be a safe environment for any gay player ready to announce their sexuality, three of the brightest young talents in the game have said.

Speaking on the US Open's first Pride Day, Stefanos Tsitsipas, Daniil Medvedev and Felix Auger-Aliassime said players should not fear coming out.

A number of the best-known women's players of all time have been lesbian, including Martina Navratilova, Billie Jean King and Amelie Mauresmo.

However, there have been few modern-era 'out' gay stars on the men's ATP Tour, with Navratilova having said in the past that those that exist have been "so far in the closet I don't know who they are".

Russian world number two Medvedev said: "From my side, I think everybody would be super open if somebody would come out on the ATP Tour.

"The other question is: are there any gays on the ATP Tour? Again, until somebody comes out, you cannot know unless you're his best friend and you know what he goes through.

"I think it's great from the US Open, this initiative. I think the ATP honestly is doing a good job, also especially internally trying to provide info and to just make sure that if anybody wants to come out, he's gonna feel safe and secure.

"All the players would be happy for the guy if he does it."

Canadian rising star Auger-Aliassime, who like Medvedev and Tsitsipas has reached round three at Flushing Meadows, explained it was important for the tour to let players be themselves.

On the women's tour, Belgian players Alison van Uytvanck and Greet Minnen are engaged, while there are a number of other players from the LGBTQ (lesbian, gay, bisexual, transgender, queer/questioning) community.

But the men's tour in recent years has seen no such prominently out players, which world number 15 Auger-Aliassime finds surprising, given the high number of professionals.

"Recently I've started doing a survey inside the ATP about the LGBTQ+ community," Auger-Aliassime said.

"It's important these days to be aware of that and to be open-minded and the ATP needs to do that, in today's time it's needed.

"The reason we don't have openly gay players on the ATP Tour, I'm not sure of the reason, but I feel me, as a player, it would be very open, very welcome. Statistically there should be some, but for now there's not."

Tsitsipas was asked whether the tour would be a "safe space" now, for any player considering coming out.

"I think so. They would be supported, for sure," said the Greek world number three, speaking on Wednesday's Pride Day in New York.

"I don't know how it is in other sports. I see no reason, for example, a tour like the ATP not to accept something like this."
