Dominic Thiem's grand slam career ended in the first round of the US Open in a straight-sets defeat to Ben Shelton on Monday.

Thiem won his sole major at Flushing Meadows in 2020, coming from two sets down to beat Alexander Zverev with no crowd present due to the Covid-19 pandemic.

In what turned out to be his final appearance at a grand slam, Shelton cruised to a 6-4 6-2 6-2 victory, before the American led the crowd in a standing ovation for Thiem.

The Austrian has struggled with a wrist injury in recent years, and announced in May that he would be retiring at the end of the 2024 tour.

Thiem was the first Austrian player in the Open Era to receive a wildcard for the men's singles at the US Open, and the first to receive wildcards to multiple grand slam events after last year’s Australian Open

"It's actually a really important moment for me because I had my greatest success of my career here on this court, in a weird 2020 in very strange and different circumstances," Thiem told the crowd.

"I'm super happy that I got the chance to play my last US Open and I can spend some time with you guys, just to say thank you and to make the time up from what we missed four years ago."

Elsewhere, fourth seed Zverev, Andrey Rublev and 2022 finalist Casper Ruud were among the winners in the first round in New York.

Two-time champion Naomi Osaka and fellow former winners Stan Wawrinka, Dominic Thiem and Bianca Andreescu were given wildcards for the upcoming US Open. 

Osaka, who lost in the final round of qualifying for the Cincinnati Open, won the first of her four grand slam titles at Flushing Meadows in 2018, winning again two years later. 

The former world number one returned to the tour this season after giving birth last year, but has struggled to find the form that led her to climb to the top of the rankings. 

The Japanese is now ranked 90th in the WTA rankings, with her best finishes coming in Doha and 's-Hertogenbosch where she reached the quarter-finals in both. 

She will be joined in the women's singles by Canada's Andreescu, who was crowned the US Open champion after her win over Serena Williams in 2019. 

The 24-year-old returned to action this year after missing nine months due to a back injury and reached the French Open third round in her first event back.

Meanwhile, Thiem headlines the wildcards in the men's singles in what will be the final grand slam of his career after confirming he will retire at the end of the season. 

The Austrian won the US Open in 2020 in an epic five-match thriller against Alexander Zverev, but has failed to his best form after sustaining a wrist injury three years ago. 

Also returning thanks to a wildcard is Wawrinka, eight years on from when he claimed the title in New York against Novak Djokovic at Flushing Meadows. 

The 39-year-old's triumph in the United States was the latest of his three career grand slams, having previously prevailed at the Australian Open and French Open. 

Alexander Zverev is looking to put previous disappointments in major tournaments behind him when he faces Carlos Alcaraz in the French Open final on Sunday.

Zverev booked his place in his maiden final in the competition with a comeback victory over Casper Ruud, who was affected by illness, winning 2-6, 6-2, 6-4, 6-2.

Zverev previously reached the US Open final in 2020, which he lost to Dominic Thiem, before having to retire in the French Open semi-final in 2022 after just two sets.

It has not been a smooth journey to the final this year, as he has been forced to go the distance and come from behind in most matches, but Zverev is confident that will only make him stronger.

"No, I think, look, to go deep and to win a Grand Slam, you have to go through difficulties, and you have to go through a lot of ups and downs," Zverev said after his win on Friday.

"Normally to win a Grand Slam you have to go through battles. You have to come back in tough five-set matches. You have to come back from difficult moments. I'm happy about the way and the path I had. I'm happy to be in a Grand Slam final and give myself the best chance to win on Sunday."

"Going from the US Open final where I was two points away to then being rolled off in a wheelchair here two years ago. It's all the path of my journey.

"Look, I'm in the final. I haven't won yet. But I just want to play my best tennis and give myself the best chance. If I am able to lift that trophy, it will mean the world to me."

Zverev has already won the Italian Open this year, his sixth Masters title, and his first since 2021.

Aiming to win his first major title, the 27-year-old looked back at his previous tournament experiences, noting how they pushed him to where he is now.

"There was one of two ways to come back from two situations," he added.

"You either come back stronger, and you come back hungrier, which I feel like I did in 2021 when I had my best year on tour so far. Didn't win a Grand Slam, but felt like I had opportunities, won the gold medal, won the most titles on tour by any player that year.

"Or you kind of go into yourself. You drop mentally a bit, as well. I'm happy that I was the sort of person that took the first path.

"Here I am. I want to give myself the best chance, and that's what I'm doing at the end of the day. We'll see how Sunday goes."

Former US Open champion Dominic Thiem will have to fight for his place at the French Open after missing out on Tuesday's wild-card invitations.

Thiem will retire later this year due to a persistent wrist injury that has derailed his career but will likely need to battle through the qualifying rounds to appear at Roland Garros for a final time.

The two-time French Open semi-finalist is currently six places away from a main-draw spot for the upcoming major, with Richard Gasquet among the eight male players to secure a wild-card invitation.

Frenchman Gasquet will equal Feliciano Lopez's 21 tournaments at Roland Garros, the joint-most appearances of any player in the Open Era.

In the women's tournament, world number 99 Alize Cornet was also invited on a wild-card pick and will appear in a women's singles grand slam main draw for the 72nd time in her career.

That is the third most in the Open Era for major appearances, behind only Venus Williams (93) and Serena Williams (81).

Former US Open champion Dominic Thiem has announced he will retire from tennis at the end of the 2024 season.

Thiem memorably fought back from two sets down to beat Alexander Zverev in the final of the 2020 tournament at Flushing Meadows, also reaching three other grand slam finals during his career.

Having reached a career-high ranking of third in the world in the aftermath of that US Open success, Thiem has since struggled with wrist and knee injuries, failing to progress beyond the second round of a major since the 2021 Australian Open. 

The Austrian failed to reach the recent Madrid Open, going down to Thanasi Kokkinakis in qualifying on the clay, which he had previously regarded as his strongest surface.

In a video posted to Instagram on Friday, the 30-year-old said: "I have to tell you a very important, and very sad but very beautiful message. The 2024 season will be my last one, I'm going to finish my career at the end of the season.

"There are reasons behind it; first of all, my wrist is not exactly the way it should be, and the second reason is my inner feeling.

"I was thinking about this decision for a very long time, thinking about my whole journey as a tennis player, which was incredible.

"I've had success and won trophies I would never have dreamed of. It was an incredible journey that I am so thankful for, but in the end I came to the conclusion that this decision is the only right one."

Andy Murray will take on fifth seed Stefanos Tsitsipas on Centre Court on Thursday after the fifth seed came through a five-set battle against Dominic Thiem.

A match that started at 11am on Tuesday finally finished just before 8pm on Wednesday with Tsitsipas claiming a 3-6 7-6 (1) 6-2 6-7 (5) 7-6 (8) victory after three hours and 56 minutes of on-court action.

That will certainly have done Murray’s chances no harm given the two-time former champion was able to relax on Wednesday having wrapped up an easy win over Ryan Peniston under the roof 24 hours previously.

Murray and Tsitsipas have met twice previously – a five-set epic at the US Open in 2021 that went the Greek’s way and an encounter on grass in Stuttgart last summer where Murray claimed one of his best wins since his hip surgery.

Tsitsipas said of facing Murray: “I’m not expecting anyone supporting (me). It’s not my first rodeo.”

It is almost exactly 10 years since the Scot first lifted the trophy in SW19, and Tsitsipas said: “I remember witnessing his first Wimbledon title. Thinking about it now gives me goosebumps because I sort of felt what he went through because it was so difficult for him to close that last game.

“Every time I see that again it gives me shivers. He’s someone who’s done so much for the sport and I’ll go into it with a lot of respect for him. He’s such a tough competitor. That (Centre Court) is almost like his living room.”

It has been an up-and-down season for Tsitsipas, who reached his second grand slam final at the Australian Open but was brushed aside by Carlos Alcaraz in the quarter-finals of the French Open and has won only two of his five matches on grass.

He resumed on Wednesday a set down to former US Open champion Thiem, who has now lost in the first round of grand slams six consecutive times as he continues to try to return to his former glories following a wrist injury.

The Austrian is at least getting closer and this match was right in the balance until the end of the deciding tie-break.

Tsitsipas’ girlfriend Paula Badosa came out to support him after winning her opening match and a final forehand pass proved to be the crucial moment.

Daniil Medvedev and Stefanos Tsitsipas progressed to the third round of the Madrid Open but there was no such luck for Felix Auger-Aliassime on Saturday.

Second seed Medvedev cruised past Italian qualifier Andrea Vavassori 6-4 6-3, teeing up a meeting with Alexander Shevchenko, who overcame Jiri Lehecka in straight sets.

Tsitsipas was made to work by Dominic Thiem, but the fourth seed battling from a set down to win 3-6 6-1 7-6 (7-5).

World number 40 Dusan Lajovic provided the shock of the day by defeating seventh seed Auger-Aliassime 6-2 3-6 7-6 (7-5).

Denis Shapovalov, the 21st seed, was another surprise second-round loser, falling 6-7 (4-7) 6-4 7-6 (7-1) to China's Zhang Zhizhen.

Taylor Fritz avoided adding to the list of notable early eliminations in the Spanish capital, the eighth seed battling to a 7-6 (13-11) 6-4 victory over Christopher O'Connell.

Fritz's fellow American Frances Tiafoe progressed with a 6-3 7-6 (7-5) triumph over Argentina's Tomas Martin Etcheverry, while 14th seed Tommy Paul crashed out after a 6-3 7-6 (7-3) defeat to Roman Safiullin.

Seeds Alex de Minaur and Sebastian Baez also navigated their way through to the third round, defeating Marco Cecchinato and Marcos Giron respectively, as did Cameron Norrie at the expense of Yosuke Watanuki.

Dominic Thiem cruised through the first round of the Madrid Open in straight sets on Thursday, while former winner Andy Murray suffered an early exit.

Thiem, who has twice finished as runner-up at this event, made short work of Britain's Kyle Edmund in a 6-4 6-1 win to set up a second-round meeting with fourth seed Stefanos Tsitsipas.

The Austrian won 86 per cent of points on his first serve (24 of 28) and saved all four break points against him as Edmund just could not get himself into the contest.

Elsewhere, Murray, who claimed titles in Madrid in 2008 and 2015, could not embark on another such run, with the veteran dispatched by Andrea Vavassori in a 6-2 7-6 (9-7) defeat.

The Italian was particularly dominant at the net against Murray, winning 13 of 17 such points, while the 35-year-old managed just five of 14.

Qualifier Roman Safiullin saw off a fightback from Chile Open winner Nicolas Jarry to progress 6-2 3-6 6-3, setting up a clash with Tommy Paul in the second round, while Dusan Lajovic followed up his win at the Srpska Open by beating Jason Kubler 6-3 6-3. 

Defending champion Carlos Alcaraz cruised into the third round of the Barcelona Open with a 6-3 6-1 straight sets rout of Nuno Borges.

The world number two thrilled his home crowd with a ruthless performance against his Portuguese opponent to reach the last 16, converting five break points along the way.

Alcaraz will be joined in the next round by third seed Casper Ruud, after the Norweigian overcame American Ben Shelton in a 6-2 7-6 (7-1) victory.

Roberto Bautista Agut will not join them, however, after he suffered a 6-2 6-2 loss to Bernabe Zapata Miralles.

At the BMW Open, Dominic Thiem set up a second-round clash with Marc-Andrea Husler after receiving a walkover against Constant Lestienne.

The 2020 US Open winner had been leading 6-3 when the match was abandoned at 0-0 in the second set, as fifth seed Sebastian Baez slipped to a 6-3 7-5 loss against home favourite Oscar Otte in Munich.

Stan Wawrinka mounted an impressive comeback victory on his return to action at the Monte Carlo Masters, but Andy Murray went out in straight sets.

The pair, both three-time grand slam winners, enjoyed contrasting fortunes in their first-round matches against Tallon Griekspoor and Alex de Minaur.

Wawrinka, who has not played since Indian Wells last month, saw off the Dutchman in a 5-7 6-3 6-4 triumph, but Murray was routed by the Australian in a 6-1 6-3 loss.

"It was really important to stay calm with myself," Wawrinka said. "In the first round you need to find your game. I am happy to get through. It was important to fight until the end."

Roberto Bautista Agut saved a match point in the second-set tie-break as he fought back to overcome Filip Krajinovic to prevail 5-7 7-6 (12-10) 6-1.

Dominic Thiem is also through following a 6-1 6-4 win over Richard Gasquet but 11th seed Cameron Norrie is out after suffering a 6-3 6-4 loss to Francisco Cerundolo.

Casper Ruud is through to the final four of the Estoril Open after a routine 6-3 6-0 victory against defending champion Sebastian Baez on Friday.

The number one seed dominated his Argentine opponent from the moment the first set went to 3-3, winning nine-straight games from there to ease to victory.

Ruud did need to save four break points in the second game of the second set, but his ability to hold serve seemed to end any resistance that Baez could muster.

The Norwegian will face Frenchman Quentin Halys in the semi-finals after his own straight-sets triumph over Dominic Thiem

Halys reached his first ever ATP Tour semi after recording a 6-1 6-4 win over the former world number three in just one hour and 19 minutes.

The other semi-final will see Miomir Kecmanovic take on Marco Cecchinato after the latter stunned third seed Alejandro Davidovich Fokina in straight sets.

The world number 96 claimed a 7-5 7-6 (7-5) victory in the first meeting between the pair to set up a last-four clash with Kecmanovic, who saw off sixth seed Bernabe Zapata Miralles with a comfortable 7-5 6-2 win.

Elsewhere, Dan Evans is the only seed remaining in the Grand Prix Hassan II as he reached the semi-finals by cruising to a 6-3 7-5 triumph over world number 201 Andrea Vavassori in Marrakech.

Evans will face Roberto Carballes Baena next after the Spaniard toppled fourth seed Tallon Griekspoor 6-3 2-6 6-2.

Second seed Lorenzo Musetti was beaten by Alexandre Muller 6-3 1-6 6-4 in a topsy-turvy encounter, and the Frenchman will now face Pavel Kotov in the final four after the Russian defeated Christopher O'Connell in a thriller, 6-3 6-7 (6-8) 7-6 (7-3).

Dominic Thiem continued to impress at the Estoril Open as he reached the quarter-finals, but second seed Hubert Hurkacz is out in Portugal.

The Austrian backed up his first round win against compatriot Sebastian Ofner with a 6-2 6-2 straight sets triumph against American Ben Shelton.

It takes the 2020 US Open winner into the last-eight where he will face Quentin Halys after the Frenchman beat fourth seed Roberto Bautista Agut in a 7-6 (7-5) 7-5 triumph.

There will be no Hurkacz however, after the Pole fell to 6-7 (7-9) 6-4 6-2 loss against the unseeded Bernabe Zapata Miralles.

Elsewhere, top seeds Lorenzo Musetti and Dan Evans are both through to the quarter-finals of the Grand Prix Hassan II.

The pair saw straight sets victories see them through the last-16, with the Italian winning 6-2 6-3 against France's Hugo Gaston and the Briton pulling out a 6-1 6-3 victory against Australia's Alexei Popyrin.

Dominic Thiem claimed his first win since February with victory at the Estoril Open.

The former US Open champion and two-time Roland Garros finalist had gone his previous four ATP Tour-level events without a win.

But Thiem, once ranked as high as third in the world, ended the drought with a 3-6 6-3 6-4 defeat of compatriot Sebastian Ofner.

He will next face American Ben Shelton, who defeated Constant Lestienne 7-5 7-5.

Meanwhile, there were three shocks at the Grand Prix Hassan II in Marrakesh.

Roberto Carballes Baena came from a set down to beat fifth seed Maxime Cressy, Alexandre Muller overcame sixth seed Richard Gasquet, and qualifier Andrea Vavassori defeated eighth seed Nicolas Jarry.

Richard Gasquet will get a showcase match against second-seed Stefanos Tsitsipas in the second round of the Miami Open after prevailing 6-4 3-6 6-1 against Christopher O'Connell on Thursday.

The biggest names in the field learned their opponents after the 32 seeded entrant received byes into the second round of the Masters 1000 event, and Tsitsipas will be desperate to avoid a third consecutive loss after quick exits at the Rotterdam Open and Indian Wells Open in recent weeks.

Fourth seed Daniil Medvedev is waiting for Roberto Carbellas Baena after he blew away Bernabe Zapata Miralles 6-0 3-0 (retired) in an all-Spanish showdown, while fifth seed Felix Auger-Aliassime will meet Brazil's Thiago Monteiro in the second round after his 6-4 7-6 (8-6) triumph over Australia's Jason Kubler.

After O'Connell and Kubler both fell, Thanasi Kokkinakis flew the flag for Australia with a 4-6 6-3 7-6 (9-7) comeback against Belgian wildcard Zizou Bergs, and his reward will be a battle against Polish eighth seed Hubert Hurkacz.

France's Gregoire Barrere earned a big matchup against 11th seed Cameron Norrie after eliminating Roman Safiullin 6-4 3-6 6-3, and Safiullin's Russian compatriot Pavel Kotov will join him on an early flight home after going down 6-2 6-2 against recent Chile Open finalist Tomas Martin Etcheverry.

Thiago Monteiro enjoyed a memorable victory on Monday as he defeated former world number three Dominic Thiem 6-1 3-6 7-6 (7-2) in his opening match of the Rio Open.

The highest-ranked Brazilian in the field made a winning start at South America's only ATP 500 event, but he had to work for it, emerging victorious after an 88-minute third set.

A raucous crowd cheered on every point down the stretch, and after saving four break point opportunities to force a tiebreaker, he jumped ahead to a 5-1 advantage and served it out.

He will face the winner between second seed Cameron Norrie and rising Argentine talent Juan Manuel Cerundolo in the next round.

Meanwhile, the top seed in action on Monday – third seed Lorenzo Musetti – continued his recent rough stretch of form with a disappointing 6-4 6-1 defeat at the hands of Chile's Nicolas Jarry.

Musetti, already ranked 18th in the world at 20 years old, has now lost four of his past five matches, while Jarry has won eight out of 10.

Jarry will play Spain's Pedro Martinez in the second round after he spoiled a potential all-Chilean matchup, eliminating Cristian Garin 7-6 (7-0) 6-4.

The only other Brazilian in action, Joao Fonseca, had no luck against Slovakia's Alex Molcan as he went down 6-0 6-3, while Bolivia's Hugo Dellien was similarly dominant in his 6-0 6-2 trouncing of Portugal's Joao Sousa.

After taking a set off world number two Carlos Alcaraz at last week's Argentina Open, Laslo Djere advanced into the second round as Facundo Bagnis retired in the second set while trailing 6-2 3-2.
