Carlos Alcaraz suffered defeat on his Laver Cup debut, as he was beaten in straight sets alongside Alexander Zverev in doubles by Taylor Fritz and Ben Shelton.

Team Europe put up a strong fight but struggled to match Fritz and Shelton, who won 7-6 (7-5) 6-4 in one hour and 37 minutes.

Alcaraz and Zverev made a slow start to the match, losing their serve in the fourth game as the Americans went on a three-game winning streak, but they pulled it back to level the tie, only to lose the tie-break.

Team Europe looked to have found their groove in the second set but failed to convert four break points in the fourth game as Fritz and Shelton levelled the score at 2-2.

A three-game winning run at the end of the set, including one more break, was enough to get Team World over the line, pulling them back to 2-2 at the end of day one.

Francisco Cerundolo had originally given Team World the lead with a shock win over Casper Ruud before Stefanos Tsitsipas and Grigor Dimitrov's wins had put Team Europe 2-1 up.

Carlos Alcaraz has led Spain to the quarter-finals of the Davis Cup Finals after a straight-sets win over Ugo Humbert.

The 21-year-old needed just one hour and 21 minutes to cruise through with a 6-3 6-3 victory, hitting 21 winners to his opponent's 14 as he backed up Roberto Bautista's win earlier on.

Bautista had to come from behind to edge past Arthur Fils, beating him 2-6 7-5 6-3, and converting 40% of his break points, bettering the Frenchman's 27%.

Spain are through in Group B, but elsewhere in Group D, US Open semi-finalist Jack Draper's return was unable to inspire Great Britain to victory.

Dan Evans was beaten by Tomas Martin Etcheverry earlier on Friday before Draper's first match since New York ended in a straight-sets 7-6 (7-4) 7-5 defeat to Francisco Cerundolo.

Despite making fewer unforced errors than the Argentinian (23 to 39), the British number one struggled to find an edge, though Evans and Neal Skupski claimed a consolation win in the doubles to make it 2-1.

They sit second in the group, missing the chance to qualify for the last eight, and now needing a win against Canada, who have been in fine form so far.   

Carlos Alcaraz got a stroke of luck as he helped Spain make a winning start to the Davis Cup Finals group-stage campaign against Czechia as Tomas Machac retired through injury.

The French Open and Wimbledon champion dropped the first set 6-7 (3-7), but rallied to finish the second 6-1, forcing a decider after getting two vital breaks.

However, Machac pulled up in the opening game of the third set with cramp and was unable to carry on after one hour and 41 minutes on the court.

It followed Roberto Bautista's flying start in their opening singles match in Group B as he cruised past Jiri Lehecka 7-6 (7-1) 6-4, with the Czech making 27 unforced errors as he failed to find an edge.

In the doubles, Alcaraz and Marcel Granollers then had to dig deep, coming from behind to beat Adam Pavlasek and Jakub Mensik in three sets to give Spain a 3-0 victory and take them top of the group. 

Meanwhile, Great Britain also made a bright start to their campaign in Group D, despite US Open semi-finalist Jack Draper sitting out.

Dan Evans got them started in Manchester with a hard-earned 7-6 (7-3) 6-2 victory over Eero Vasa of Finland, converting both of his break points in the second set.

Billy Harris followed that up with an impressive tournament debut, looking unflappable as he earned the hosts an unattainable lead with his 6-4 7-6 (7-4) win over Otto Virtanen.

Finland got themselves on the board in the doubles though, with Evans and Neal Skupski unable to get the better of Harri Heliovaara and Virtanen ensuring it was only a 2-1 loss. 

Elsewhere, the United States joined Germany at the top of Group C with their 3-0 win over Chile and Italy's Matteo Arnaldi held off a spirited Thiago Monteiro to put them in control against Brazil in Group A after Matteo Berrettini's earlier victory.

Carlos Alcaraz suffered a shock defeat to Botic Van de Zandschulp at the US Open.

Alcaraz, the French Open and Wimbledon champion, had been tipped to win a third major of the year at Flushing Meadows.

However, the Spaniard's hopes of becoming just the third player to win the French Open, Wimbledon and US Open in the same season were dashed by unseeded Dutchman Van de Zandschulp in the second round.

Van de Zandschulp prevailed 6-1 7-5 6-4 to cause the tournament's first huge shock.

"I think my level stayed at the same point all the match," said Alcaraz, who had won his previous 15 grand slam matches.

"It wasn't enough to win the match or to give myself the chance to get into the match or try to give myself chances.

"I didn't feel well hitting the ball. I think I made a lot of mistakes. When I wanted to come back, it was too late.

"He didn't make a lot of mistakes that I thought he was going to do so I was confused a little bit. I didn't know how to manage that.

"I came here with not as much energy as I thought that I was going to come with. But I don't want to put that as an excuse."

Data Debrief: Dutch delight

This was Van de Zandschulp's second career win over a top-five opponent, as he became just the second Dutch player to achieve that feat at the US Open, while he is the first from his nation to defeat a top-three player since 1991. 

Indeed, Van de Zandschulp, who will face Jack Draper next, snapped a 43-match losing streak for Dutch players against ATP top 10 opponents at the majors.

Carlos Alcaraz insisted he is not thinking about Rafael Nadal's grand slam record following his triumph over Australian qualifier Li Tu at the US Open. 

Alcaraz was able to overcome a scrappy second set to win 6-2 4-6 6-3 6-1 at Flushing Meadows, serving eight aces and producing 50 winners to his opponents' 19. 

The Spaniard started strongly, finding himself a set and a break to the good before four double faults in the second allowed Tu a way back into the contest. 

However, the world number three would recover, dominating the third as he confirmed his progression to the next round with a love game in the final set. 

Alcaraz is aiming to become the third man in history after Rod Laver and Nadal to win the French Open, Wimbledon and the US Open in the same calendar year. 

"Well, after this interview I’m going to try to pretend I never heard that," Alcaraz told ESPN when asked about the statistic. 

"Obviously it would be a great achievement if I make it, but it is going to be difficult."

The Olympic silver medallist faces Botic van de Zandschulp in the next round after the Dutchman defeated Denis Shapovalov in straight sets. 

Data Debrief: Alcaraz continues grand slam winning streak

Alcaraz's triumph at Flushing Meadows was his 15th grand slam victory in a row, last losing in a major tournament against Alexander Zverev at the Australian Open quarter-finals. 

Among players to begin their career in the Open Era, only John McEnroe (69) has achieved 60 men's singles match wins at grand slam events in fewer matches than Alcaraz (70), following the latter's win over Tu.

Carlos Alcaraz insists his recent ankle concern is nothing serious and that he will "be at 100%" for this year's US Open.

The Spaniard is seeking his second triumph at Flushing Meadows, where he was victorious two years ago, as well as a third major of the season following his success at the French Open and Wimbledon.

Although, there were briefly question marks over Alcaraz's participation in the year's final slam after he pulled out of practice on Friday with an ankle injury. 

Nevertheless, he said the reason for not continuing the session was precautionary above anything else.

"After a few hours after finishing my practice, I have not felt anything and everything is fine and under control," said Alcaraz, who begins his campaign against Li Tu on Wednesday "I think it is not going to be anything serious. 

"We will take care of it in the next few days and we will be extra cautious. I think it was just a scary moment, but I am sure I will be at 100%."

Alcaraz also reflected on his Olympic gold medal match against Novak Djokovic earlier this month, in which the Serb avenged his Wimbledon showpiece defeat to complete a career golden slam.

The Spaniard admitted it was a defeat that hurt, but made him more determined to go the extra step in four years' time.

"It was one of the most important finals of my career, my life," he said. "I know the Olympic Games is every four years, so I don't know if I'm going to have another chance to win the gold. I'm going fight for it, for sure, at the next Olympic Games.

"It was a difficult moment [for me to] deal with, losing the gold medal in a really close match when I had opportunities, but in front of me, I had a really good player that day.

"[Djokovic] was fighting for the same thing as me and he deserved it, and days after the Olympics, I realised that I won the silver medal. It was a great achievement for me."

When Novak Djokovic triumphed at Flushing Meadows last year, he surely thought the outright record for grand slam titles was all but his.

Yet just shy of a year later, Djokovic is still waiting for his 25th major win - and the one that would take him clear of Margaret Court, making him the undisputed greatest of all time.

He came close at Wimbledon, but Carlos Alcaraz ultimately had too much, with the Spaniard winning the final in straight sets.

Alcaraz, the 2022 US Open champion, will be one of the most likely candidates scrapping it out for Djokovic's crown over the next two weeks, along with world number one Jannik Sinner.

Djokovic avenged that Wimbledon defeat with a 7-6 (7-3) 7-6 (7-2) win over Alcaraz in the final of the Paris Olympics, with the 37-year-old ending his wait for a gold medal.

But while that gold is now hanging around his neck (or, in his trophy cabinet, which must be pretty big), it did not settle Djokovic's desire for that record-breaking major triumph. His next tournament win would also bring up his 100th career title.

Should Djokovic fail to defend his crown, though, it will be just the fourth year since he won his first major in 2008 that he has not won a grand slam in a season, after 2009, 2010 and 2017.

But what do the Opta statistics tell us about the key storylines ahead of the US Open?

Can Djokovic dominate?

Jimmy Connors, Pete Sampras and Roger Federer have won the US Open a joint-record five times each. Should Djokovic win, he will join that illustrious trio on five Flushing Meadows titles.

Connors has appeared in (115) and won (98) the most singles matches of any player in the Open Era at the tournament, but Djokovic (88) has won the most among active players and could equal Federer (89) for the second-most by defeating Radu Albot in round one on Monday.

Should Djokovic reach the second round, he will also match Federer's tally of matches played in the competition (103).

At 87.1%, Djokovic holds the second-best win percentage at the US Open in the Open Era of players to have featured in at least 30 matches at the event, after Sampras (88.8%).

The Serbian great, who became the oldest player to win the men's singles at the US Open when he succeeded at the age of 36 years and 111 days in 2023, has featured in the most men's singles finals in the tournament's history (10). He is the only player in the Open Era to have reached 10+ finals at multiple grand slams, having also done so at the Australian Open and Wimbledon.

Should he reach the quarter-finals, barring walkovers, Djokovic will surpass Federer (429) for the most matches played at grand slams in the Open Era. If he were to then reach the last four, he would be the first male to appear in 50 major semi-finals, and the second player overall after Chris Evert (52). 

Connors (109) and Federer (103) are the only players to win 100 Tour-level titles, while Djokovic is chasing his 72nd hard-court title, which would take him clear of Federer (71).

Could the kids have too much?

Djokovic may have outfought Alcaraz at the Olympics, but that was only after he had been dispatched by the world number three at the All-England Club.

Alcaraz, who said he had played his worst-ever tennis during a shock defeat to Gael Monfils at the Cincinnati Open earlier this month, could become only the third player in the Open Era to win the men's singles title at Roland-Garros, Wimbledon and the US Open in the same year after Rod Laver (1968) and Rafael Nadal (2010).

Aged 21 years and 126 days, he would also be the youngest man to win a singles title at three grand slams in a calendar year. He won his first major title at Flushing Meadows two years ago, and reached the semi-finals last season, losing to eventual runner-up Daniil Medvedev.

Then there is the world number one, and top seed, Sinner. The Italian was forced to miss the Olympics due to illness, but after going out in the last eight at the Canadian Open, he returned to form with a sensational run to triumph in Cincinnati.

That was his fourth title of the season. Excluding team events, Sinner (23 years, 23 days) could become the youngest player to win five ATP trophies on hard court in a calendar year since Andy Murray in 2009.

Since the Australian Open switched to hard court in 1988, Sinner could become only the fourth male to win that competition and US Open in the same year, after Mats Wilander (1988), Roger Federer (2004, 2006 and 2007) and Djokovic (2011, 2015 and 2023).

Sinner has now won three ATP 1000 hard-court titles in total. Across the past decade, only three players have won more Masters titles on the surface: Djokovic (17), Federer (seven) and Medvedev (five).

The last top seed to lose in their opening match at the US Open was Stefan Edberg, who lost to Alexander Volkov in 1990.

Indeed, the US Open is certainly not a tournament in which you can confidently say "expect the unexpected" when it comes to major shocks.

Only two top seeds in the Open Era have been eliminated in the first round of the men's singles – John Newcombe (1971) and Stefan Edberg (1990). Andre Agassi is the last first seed to not reach the second week at the event, losing to Arnaud Clement in straight sets back in 2000. 

Carlos Alcaraz will begin his bid for a third straight grand slam success against a qualifier at the US Open, while top seed Jannik Sinner will face Mackenzie McDonald in the first round.

Alcaraz won his fourth major title at Wimbledon in July, dominating Novak Djokovic in the final after also triumphing at the 2022 US Open, Wimbledon in 2023 and the French Open earlier this year.

Should the Spaniard progress through his first-round match, he could take on Botic van de Zandschulp in round two and Britain's Jack Draper in the third round.

Seeded third, Alcaraz could face world number one Sinner in the semi-finals, with the Italian starting his campaign against a home favourite in McDonald.

Sinner recently avoided a ban after twice testing positive for banned substance clostebol, with an independent tribunal finding he was inadvertently given the steroid in an over-the-counter spray by his physiotherapist Giacomo Naldi.

On the other side of the men's draw, Djokovic will also start against a qualifier as he bids to finally surpass Margaret Court's overall record of 24 grand slam titles.

Djokovic won his 24th major crown at the 2023 tournament at Flushing Meadows, beating Daniil Medvedev in straight sets in the final.

He has struggled to find top gear at this year's grand slams, though he did claim his first Olympic gold medal by beating Alcaraz in the showpiece match at Roland-Garros.

In the women's draw, top seed Iga Swiatek will start against a qualifier while Coco Gauff will open her title defence by taking on Varvara Gracheva, with a testing third-round date with Elina Svitolina potentially on the cards for the third-seeded American.

Aryna Sabalenka joins Swiatek in facing a qualifier first, while there is a tricky draw for 2021 US Open winner Emma Raducanu, who is set for her first Flushing Meadows appearance since 2022.

She will take on the United States' 2020 Australian Open winner Sofia Kenin, with the victor set to face another American in round two, in either Shelby Rogers or sixth seed Jessica Pegula. 

The first round of the US Open begins on Monday, with the women's singles final set for September 7 and the men's showpiece match taking place one day later.

Carlos Alcaraz is determined to put his emotional outburst during the Cincinnati Open behind him as he prepares for the start of the US Open next week.

The Spaniard has enjoyed an unforgettable three months, winning the French Open and Wimbledon back-to-back before earning the silver medal at the Olympics.

However, his return to hard court has not been so smooth as he suffered a shock defeat to Gael Monfils in the second round in Cincinnati last week.

After cruising through the first set, Alcaraz's match was delayed by rain with the second set tied at 6-6, and the Frenchman rallied to win the tie-break and the decider.

The world number three's frustration was evident during the match as he smashed his racquet on the court four times midway through the third set.

Alcaraz admitted he struggled to adapt to the court's surface but is ready to step up his preparation for the US Open to avoid the same issues.

"I couldn't play. Honestly, I'd been practising really well," Alcaraz said.

"The previous days, I was feeling great, hitting the ball clear, moving well. I don't know what happened.

"I don't know how I felt like this. I couldn't control myself.

"It's really difficult to find some good stuff from this match. So, I want to forget it and try to move on. I'll go to New York and try to practise well, get used to those courts."

Alcaraz won the first of his four grand slams at Flushing Meadows as a teenager during his breakout tournament.

While a third grand slam title of 2024 may be on his mind, Alcaraz is also targeting a different goal for the end of the year, as he aims to leapfrog Jannik Sinner and Novak Djokovic to become the world number one.

"I'm focused on going to every tournament, thinking about playing great tennis, doing a good result to get better in the race," Alcaraz added.

"Ending the year as number one is one of my main goals."

Jannik Sinner has been cleared after twice testing positive for a banned substance in March.

The world number one tested positive for low levels of a metabolite of clostebol – a steroid that can be used to build muscle mass – during Indian Wells.

Sinner was notified about the positive tests in April and was originally given a provisional suspension, but he successfully challenged it and was able to keep playing.

The Italian had been inadvertently contaminated by the substance from his physiotherapist, who had used an over-the-counter spray for a cut on his own hand before treating Sinner, the International Tennis Integrity Agency's (ITIA) investigation found.

The ITIA accepted the explanation that the contamination was not intentional, and the 23-year-old was cleared of all fault or negligence by an independent tribunal last week.

Sinner will still lose the ranking points won at Indian Wells, where he was beaten in the semi-finals by eventual champion Carlos Alcaraz.

"I will now put this challenging and deeply unfortunate period behind me," Sinner said in his statement.

"I will continue to do everything I can to ensure I continue to comply with the ITIA's anti-doping programme, and I have a team around me that are meticulous in their own compliance."

The ATP praised the work done by the ITIA during their investigation to get to the right outcomes about the Cincinnati Open winner.

"We are encouraged that no fault or negligence has been found on Jannik Sinner's part," the ATP posted on X.

"We would also like to acknowledge the robustness of the investigation process and independent evaluation of the facts under the Tennis Anti-Doping Programme (TADP), which has allowed him to continue competing.

"This has been a challenging matter for Jannik and his team and underscores the need for players and their entourages to take utmost care in the use of products or treatments. Integrity is paramount in our sport."

Sinner will next be in action at the US Open, which starts on August 26 in New York.

Carlos Alcaraz admitted he played "the worst match of his career" as he suffered a shock defeat to Gael Monfils in the Cincinnati Open on Friday.

The Spaniard started well, racing through the first set before rain delayed proceedings with the second set level at 6-6.

When play resumed 24 hours later, Monfils picked up where he left off, winning the tie-break and the final set, to book a place in the last 16 at Alcaraz's expense.

After struggling to find his footing, Alcaraz says he found it hard to adapt while playing on Centre Court.

"It was really, really tough for me. I felt like it was the worst match that I've ever played in my career. Couldn't play, honestly," Alcaraz said.

"I've been practising really well here in this tournament. The previous days, I was feeling great, hitting the ball clear, you know, moving well.

"Probably I felt like it was another sport playing on the Centre Court [than] on the other courts. The balls were faster on the Centre Court bounced much, much, more than other courts.

"I don't know how I felt like this way, but, honestly, I couldn't control myself. I couldn't be better. So, this match it was impossible to win, and that's all."

Alcaraz's frustration was clear to see as he smashed his racquet on the court four times midway through the third set.

"I felt sometimes that I wanted to break the racquet," Alcaraz added. "It never happened before, because I could control myself in those situations, in those feelings, and most of the time I could control myself, and it could go better in the matches or in the situation that I've been feeling before.

"[This time] I couldn't control myself because, as I said, I was feeling that I was not playing any kind of tennis. So, it was really frustrating for me.

"There is some point that I want to leave the court. I don't want to be on the court anymore.

"So, it was really hurtful moment for me, and that's it. I think some players or a lot of players during their careers and during some certain moments, they can't control themselves, and it was one of those moments for me."

Alcaraz will be chasing his third grand slam title of the year at the US Open, which starts on August 26 in New York. 

Carlos Alcaraz suffered a shock defeat at the Cincinnati Open as Gael Monfils came from a set down to prevail from a rain-delayed encounter.

Monfils was 3-1 up in a second-set tie-break before rain stopped play on Thursday, but returned 24 hours later to win 4-6 7-6 (7-5) 6-4.

Once play resumed on Friday, Monfils continued where he left off but squandered three set points before eventually taking the tie this distance. 

Last year's runner-up Alcaraz struggled in the opening exchanges, with his French opponent finding a decisive break in the third game as Monfils took control of proceedings in Ohio. 

And Monfils' experience ultimately told, as the 37-year-old held out for the remainder of his service games to set up a meeting with Holger Rune in the last 16, condemning Alcaraz to a shock exit.

World number one Jannik Sinner, meanwhile, had no need to take to the court on his 23rd birthday, as he was handed a walkover following Jordan Thompson's withdrawal.

Data Debrief: The old head prevails

Monfils is the oldest player to defeat an opponent ranked in the ATP top-three since Jimmy Connors defeated Michael Stich in Memphis in 1992.

The world number 46 starred on serve, firing 15 aces throughout the contest compared to Alcaraz's seven, while also clawing back six of the seven break points he faced.

Carlos Alcaraz said he will remember this summer "for the rest of his life" despite his defeat to Novak Djokovic at the Paris Olympics. 

Alcaraz, who has already won two grand slams at the French Open and Wimbledon this year, finished with a silver medal at the Games earlier this month. 

The Spaniard will take part in this week's Cincinnati Open where he will face either Gael Monfils or recent Canadian Open winner Alexei Popyrin in the second round. 

Alcaraz has the opportunity to claim a second US Open title in two weeks time, but had the chance to reflect on an incredible few months ahead of his first match in Ohio. 

“It has been some incredible months in my life and career after winning Roland-Garros, a tournament that I was very excited to win, and of course Wimbledon, which is wonderful to be able to win it,” Alcaraz told the ATP Tour.

“Also, one of my dreams was to win an Olympic medal. I have enjoyed a lot these last few months. They were incredible and I enjoyed it a lot.

“I am also very happy with my tennis and the way I handled different situations. I think I have improved a lot as a player, so I am very happy.

“Of course, in tennis the season is not over, and we have to carry on pushing our best in each tournament but, of course, I will remember these months [for] the rest of my life.”

Alcaraz also partnered up with fellow compatriot Rafael Nadal in the men's doubles at Roland-Garros during the Olympics in the French capital. 

The Spanish pair, dubbed 'Nadalcaraz' at the Games, lost in the quarter-finals to America's fourth-seeded duo Austin Krajicek and Rajeev Ram in straight sets. 

And while his journey with the 22-time grand slam champion fell short of a medal, Alcaraz said it was a dream come true to play alongside one of his sporting heroes. 

“It was a great experience, talking with Rafa off the court, knowing each other much better off the court. It was a great experience, obviously, playing doubles together," Alcaraz said.

“It was something that I will never forget, for sure. I learned a lot talking to him on court, off the court as well.

“I think we played great tennis in doubles, even if we are not used to playing doubles very often.

“A little bit disappointing at the end, because we thought that we could do it better, but in general, we were happy.

“Obviously talking about myself, I reached my dream, my dream came true, playing doubles alongside Rafa.”

Novak Djokovic has backed Carlos Alcaraz to win Olympic gold in the future after edging the Spaniard in a tightly contested final on Sunday.

The Serb secured the top prize at the Games for the first time, completing a career golden slam with a 7-6 (7-3) 7-6 (7-2) victory.

Alcaraz, who beat Djokovic at Wimbledon to claim his second grand slam of the season last month, was reduced to tears after the match, having to step away from his post-match interview.

Djokovic was full of praise for the Spaniard's performance and predicted the silver medal is only the start of his success at the Olympics.

Another epic final, Carlos Alcaraz. El Clasico," Djokovic posted on X.

"Congratulations to you and your team for an excellent Olympics. Considering your age, your energy and the way you play, you probably have 20 more Olympics ahead of you.

"Your gold will come. Until next time, amigo."

Djokovic's appearance in Paris was his fifth Games for Serbia, and he became just the second player in the Open Era to win all four grand slams, the Olympics gold medal and the ATP Tour Finals, after Andre Agassi.

He is also the oldest player to secure the top prize in either the men's or women's singles at 37 years and 74 days since the sport returned to the schedule in 1988. 

Carlos Alcaraz says the pressure got to him in the Olympic Games final as he lost out on the gold medal to Novak Djokovic.

In a hard-fought battle, Djokovic claimed his first-ever gold medal with a 7-6 (7-3) 7-6 (7-2) victory at Roland-Garros, avenging his Wimbledon final defeat to the Spaniard last month.

Alcaraz, playing in the Olympics for the first time, was chasing the top prize to add to this year's trophy haul, having already won the French Open and Wimbledon.

The 21-year-old was the second-youngest men's singles finalist at the Olympics in tennis history, after Robert LeRoy in St. Louis in 1904, but missed the chance to become the youngest-ever champion in the competition.

And Alcaraz admitted the pressure of playing for his country weighed on him, causing him to falter at key moments.

"It was a different type of pressure," Alcaraz said. "Everyone in Spain wanted me to win the gold, and I wanted to win the gold as well.

"In those difficult moments I usually raise my level, but I wasn't able to do that today. Probably, I felt the pressure in those situations. You play four grand slams every year, the Olympics is only once every four years.

"Obviously, this week, this tournament has been really special for me. I'm going to take it for the rest of my life, for the rest of my career, for sure. Playing with Rafa [Nadal in the men's doubles], getting my first Olympics medal - hopefully not the last one - it's been a special one."
