Daniil Medvedev came from a set behind to beat Jannik Sinner in the Rotterdam Open final and land his 16th ATP Tour title. 

A 5-7 6-2 6-2 win for Medvedev gave the 27-year-old Russian his first trophy of the year, extending his career head-to-head record to 5-0 against Sinner.

The run from Medvedev this week has secured his return to the top 10 in the rankings, with the former number one set to go up three places to number eight on Monday.

Victory came in sharp contrast to Medvedev's last two appearances at the tournament, when he suffered first-round losses in 2020 to Vasek Pospisil and in 2021 to Dusan Lajovic.

Medvedev said after his win: "Thanks to all members of my team who are with me no matter what: some tough moments, some good moments, and we continue growing.

"The last two times I played here were terrible, and I'm happy to make it better this year."

Medvedev and Sinner's past meetings had curiously all come on indoor hard courts, as this also did.

Sinner won a title last week at the Open Sud de France in Montpellier, so the 21-year-old was not wanting for confidence as he looked to finally register a win over Medvedev.

The Italian out-rallied Medvedev at the end of the first set to snatch the vital break, but he could not ride that momentum into the early stages of the second.

An early break went the way of 2021 US Open winner Medvedev, whose remarkable defence was a key factor as the comeback gathered steam.

A double fault from Sinner handed Medvedev a 4-1 lead and a double break, nudging the match towards the decider.

When it came, first blood went to Medvedev as Sinner netted a backhand to give up a break in the third game.

The Moscow man saved a break point in the next game to stay ahead, and that setback left Sinner sapped, his challenge fading as Medvedev maintained an impressively high level.

Daniil Medvedev had no problems against Grigor Dimitrov as he eased into Sunday's Rotterdam Open final.

The former world number one took just 82 minutes to win 6-1 6-2, converting six of 13 break points against his Bulgarian opponent.

Medvedev rises back up to 10th in the world rankings after the win, and will go ninth if he can claim the title.

"It was an amazing match," Medvedev said after his victory. "The score [looks] easy, but the match was not. I felt physically like I was playing five sets.

"It would be amazing [to win the tournament]. Every time I come here, and I think it is my fifth time here, everywhere there are photos of the winners and their names.

"I don't remember who won it first time, but then Arthur Ashe won it [twice]. Then [John] McEnroe, [Bjorn] Borg, [Stefan] Edberg, and I'm like, 'Well, that tournament has a history for sure'. To add my name there would be amazing, but for this I need to play well in the final."

That final will be against Jannik Sinner after the Italian overcame spirited home wildcard Tallon Griekspoor.

It was Sinner's impressive serve that saw him through 7-5 7-6 (7-5), not facing a single break point, and ruthlessly taking the only one he carved out all match to take the first set.

He kept his nerve to see out a second set tie-break, and now has the chance to follow up last week's Open Sud de France title with another in Rotterdam.

Daniil Medvedev was at his brilliant best as he ended Felix Auger-Aliassime's title defence at the Rotterdam Open.

Former world number one Medvedev committed just five unforced errors in a 6-2 6-4 win on Friday that saw him progress to the semi-finals.

"Today was my best match of the week, but I have to build on this," Medvedev said afterwards.

"Usually, the best weeks you play, many times you're going to play your best tennis in the last match, so that's definitely a goal.

"But I'm happy with my level today, beating someone like Felix in straight sets."

He will next face Grigor Dimitrov, who needed three sets to see off Alex de Minaur.

Dimitrov saved two match points in claiming a 6-3 3-6 7-6 (8-6) victory but seemingly has an uphill challenge having lost four of his six matches against Medvedev.

"I kind of know the plan for the game,” Medvedev added of his clash with Dimitrov. "The thing is, he is going to try to do the same, to make up a good plan. If we take the last two matches, it's 1-1. So I always say a new match is a new match, no matter the head to head. 

"I'm preparing for a tough one tomorrow, he's such a great player and today was a great match from him, a great comeback actually. So I'm ready for the tough fight tomorrow."

Jannik Sinner was just as impressive as Medvedev, cruising to a 6-1 6-3 victory over three-time grand slam champion Stan Wawrinka.

Sinner, who won the Open Sud de France last week and has already dumped out top seed Stefanos Tsitsipas, will face Tallon Griekspoor after the Dutchman's win over fellow home hope Gijs Brouwer.

Lorenzo Musetti won his opening match at the Argentina Open in comfortable fashion, defeating hometown hero Pedro Cachin 6-2 6-3 on Thursday.

World number 20 Musetti is still just 20 years old, making him the third-youngest player inside the top-40. The only younger players are 19-year-olds Carlos Alcaraz (world number two) and Holger Rune (world number nine).

The talented Italian has two ATP Tour titles to his name, but none outside of Europe, and he will hope to change that after he advanced to the quarter-finals in Buenos Aires.

Musetti will play Peru's Juan Pablo Varillas next after he prevailed 6-4 6-4 against former world number three Dominic Thiem.

Fifth seed Francisco Cerundolo did his part to set up an all-Argentine quarter-final clash after dominating Jaume Munar 6-2 6-1, but compatriot Diego Schwartzman could not hold up his end of the deal, falling 6-1 6-3 to Spain's Bernabe Zapata Miralles.

Meanwhile, world number seven Taylor Fritz made a winning start to his Delray Beach Open campaign, defeating Ecuador's Emilio Gomez 6-4 6-3.

Fritz will play France's Adrian Mannarino in the quarter-final after the 34-year-old veteran eliminated 24-year-old American J.J. Wolf 7-5 6-2.

Second seed Tommy Paul was too strong for Denis Kudla in a 6-3 6-4 triumph, and he will play Radu Albot for a place in the semi-final after the Romanian emerged the 6-4 6-4 victor against Australia's Aleksandar Vukic.

Defending champion Felix Auger-Aliassime must overcome a dismal record against Daniil Medvedev to go any further at the Rotterdam Open after both won on Thursday to set up a heavyweight quarter-final, while Stefanos Tsitsipas crashed out.

Third seed Auger-Aliassime beat French qualifier Gregoire Barrere 6-4 6-3, while Medvedev earned a 6-2 6-2 victory against Dutchman Botic van de Zandschulp.

Despite being the higher-ranked of the two at present, Canadian Auger-Aliassime has a 0-4 career record against Russian Medvedev.

Those losses include a painful defeat from two sets up in the 2022 Australian Open quarter-finals, and a US Open semi-final knockout blow in the previous season.

It is a record that is all the more surprising considering Auger-Aliassime has wins over Novak Djokovic, Rafael Nadal, Roger Federer, Andy Murray and Carlos Alcaraz to his name.

Auger-Aliassime sits eighth on the ATP ranking list, three places clear of former number one Medvedev, who is relishing their clash on Friday.

Medvedev said on Amazon Prime: "Felix is a top player. He won here last year and played amazing at the end of last season. I'm looking forward to a tough match, and hopefully I can be at my best.

"He's going to take his opportunities. He's going to go for it when he has the chance. So I will need to be at my best and everything has to be better."

Top seed and Australian Open runner-up Tsitsipas was beaten 6-4 6-3 by Jannik Sinner, with last week's Open Sud de France champion winning in an hour and 21 minutes to set up a quarter-final against Stan Wawrinka.

It was Sinner's first career win over a top-three opponent. The Italian held a 0-8 record against such opponents coming into this match.

Fourth seed Holger Rune is also out after retiring hurt while 6-4 4-0 down to Dutch wildcard Gijs Brouwer, who advances to play compatriot Tallon Griekspoor.

Australian Alex de Minaur advanced to the final eight with a 7-5 3-6 6-3 win over American Maxime Cressy, earning a shot at Grigor Dimitrov next.

Carlos Alcaraz overcame a second-set hiccup to win on his return to the ATP Tour over Laslo Djere in the second round at the Argentina Open on Wednesday.

Alcaraz, who rose to the world number one ranking after last year's US Open triumph, won 6-2 4-6 6-2 in two hours and one minute over the Serbian in Buenos Aires.

The match marked top seed Alcaraz's first since losing to Holger Rune in the Paris Masters quarter-finals, having missed last month's Australian Open following abdominal and hamstring injuries.

The Spanish 19-year-old displayed his trademark forehand on occasion, while he was at his tenacious best, saving six of seven break points generated by Djere.

"It's a great feeling to win again," Alcaraz said post-match. "It's been a long time for me with no competition, with no matches, just recovering. Finally, I got my first win of 2023."

Alcaraz will face Serbian qualifier Dusan Lajovic next after he won 6-3 6-1 over local Camilo Ugo Carabelli.

Second seed Cameron Norrie was pushed for three hours by Argentinian wild card Facundo Diaz Acosta before prevailing 4-6 7-5 7-6 (8-6). Diaz Acosta got within two points of victory on three occasions but could not capitalise.

Norrie will face another Argentinian in the third round, with Tomas Martin Etcheverry progressing with a 4-6 6-1 6-2 win over Roberto Carballes Baena.

Third seed Denis Shapovalov was a shock second-round casualty at the Delray Beach Open after going down in here sets to Michael Mmoh on Wednesday.

The American, who is ranked 87th in the world, triumphed 7-5 3-6 6-3 in two hours and 20 minutes at the event in Florida.

The Canadian committed 30 unforced errors across the match compared to Mmoh's 16. Shapovalov also generated 10 break points but only capitalized on two, while Mmoh converted three of five.

Mmoh will take on countryman Mackenzie McDonald who won 6-3 3-6 6-2 over fifth seed Yoshihito Nishioka.

Fourth seed Miomir Kecmanovic cruised past qualifier Nuno Borges 6-3 7-5, while Marcos Giron also progressed in straight sets over Matija Pecotic.

Carlos Alcaraz has described Novak Djokovic as "like a god", but fully intends to take his world number one spot back from the Serbian.

Alcaraz has been out of action for four months through injury, but will return at the Argentina Open in Buenos Aires on Wednesday when he faces another Serbian, Laslo Djere.

The 19-year-old had been top of the men's world rankings when he suffered a leg muscle injury, causing him to miss the Australian Open.

Djokovic leapfrogged Alcaraz into top spot after he won in Melbourne, beating Stefanos Tsitsipas in last month's final.

"It has been a long time [I spent] at No. 1," Alcaraz said. "Now it's a goal for me to recover No. 1 and try to do my best in these tournaments to be back on that number. I'm looking for that."

The young star acknowledged that he has a big job on his hands though, recognising that Djokovic is one of the greatest of all time.

"He has no weaknesses. Every shot, it's amazing," he said. "His physical condition is amazing, his mental condition is amazing.

"He's like a god and I admire him over the years staying at the same level, staying at the top. It's really, really difficult and I admire that."

Despite his ultimate lofty goals, Alcaraz does not want to push himself too fast after his injury, and suggested his main aim at the Argentina Open is just to regain fitness and confidence.

"It's tough to play my first tournament after a long time for me, after four months," he said. "So it's going to be really, really tough to win the tournament or be close to winning.

"My hope is to feel that I am okay with the injury, with my body and try to play well."

Part-timer Matija Pecotic had to put a request in for another day off work to play in the second round of the Delray Beach Open after pulling off a shock win over Jack Sock.

The Croatian came through qualifying to make his ATP Tour main-draw debut in Florida and the 33-year-old is through to the last 16 after a 4-6 6-2 6-2 victory against former world number eight Sock on Tuesday.

World number 784 Pecotic has a full-time job in finance and he will be in the money after setting up a meeting with Marcos Giron in the last 16 of the ATP 250 event.

The Princeton and Harvard graduate's boss was in his box to watch him see off Sock and Pecotic hopes he will get a chance to book a quarter-final spot on Wednesday rather than return to balancing the books.

He quipped: "I had to leave work early today. I had to send an email to the whole team. [My boss] let me off. I'm going to have to ask for another day off tomorrow."

Pecotic, who served 10 aces and struck 30 winners, added: "I certainly didn't expect to win, but certainly didn't come into the match thinking that I'm definitely going to lose.

"You've got to be realistic. This is a former top 10 guy with an incredible amount of tennis experience, with a huge serve.

"He came out serving 134 [mph] on the first serve. It would be arrogant to think that I'm going to come out and expect to win.

"But I certainly figured if I could sink my teeth into the match and work on the two or three patterns that I prepared before, that I'm going to have a chance. And then let's see... if I was going to fall under pressure or not be able to serve it out at some point. But I didn't and I got the win."

Playing in his hometown of Buenos Aires, Francisco Cerundolo avenged his younger brother's defeat at the Argentina Open by defeating Yannick Hanfmann 6-2 4-6 7-5 on Tuesday.

Francisco's younger brother Juan Martin had been eliminated by Hanfmann in the qualifying stage, but the fifth seed got one back on the German after leading the break point opportunities 17 to six.

Fifth-seed Cerundolo was the highest seed in action Tuesday, while sixth seed Sebastian Baez fell 3-6 7-6 (7-5) 6-3 to Serbia's Dusan Lajovic.

In the only all-Argentine clash it was Facundo Diaz Acosta prevailing 7-6 (7-5) 7-5 against Federico Coria – who sits over 100 places higher in the rankings – while Roberto Carballes Baena collected a seeded scalp with a 7-5 6-4 win over Spanish compatriot Albert Ramos-Vinolas.

Meanwhile, Australian Open quarter-finalist Ben Shelton was eliminated from his own hometown tournament as the Florida resident was bounced out of the Delray Beach Open 6-4 6-4 by Marcos Giron.

Shelton beat J.J. Wolf to reach that grand slam quarter-final, but Wolf will be moving on after he emerged with a 7-5 6-3 win against Ilya Ivashka. 

Wolf will play France's Adrian Mannarino following his 4-6 6-3 6-4 triumph over Germany's Daniel Altmaier, and Mackenzie McDonald will get a shot at redemption against fifth seed Yoshihito Nishioka after a comfortable 6-2 6-2 success against Taro Daniel.

McDonald and Nishioka have played twice this year – once at the Adelaide Invitational and once at the Australian Open – and Nishioka has won all five sets.

It was also a day 33-year-old Matija Pecotic will never forget, with the world number 784 winning his first ever ATP Tour match by defeating Jack Sock 4-6 6-2 6-2.

Rotterdam Open top seed Stefanos Tsitsipas and defending champion Felix Auger-Aliassime were joined by Daniil Medvedev in progressing through their first-round ties.

Auger-Aliassime won his first Tour-level title at the event last year and went from strength to strength in 2022, winning another three singles trophies.

The world number eight, seeded third, started his title defence with a convincing 6-2 6-3 defeat of Italy's Lorenzo Sonego on Tuesday.

"Of course, I was hoping to win and get through, but 6-2, 6-3 is a great performance against a player that is tricky like he is... it's a great way to start the week," said Auger-Aliassime, who needed just 82 minutes to clinch victory and set up a last-16 meeting with qualifier Gregoire Barrere.

The Canadian is relishing his title defence, and feels he is a stronger competitor than this time last year in a warning shot to his rivals.

He added: "Last year was an amazing year, but this year is a different one. I think I'm a better player overall.

"Of course, the best thing I can do compared to last year is win again, so hopefully I can do that. The draw is really strong, but I'm confident if I can keep playing the way I did today I'll get my chances and then we'll see."

Auger-Aliassime might be the reigning champion, but world number three Tsitsipas is the favourite.

Emil Ruusuvuori was no match for Australian Open runner-up, who prevailed 7-5 6-1 and has a 13-1 record for the season.

"The process that you get to repeat these things over and over again, it gives you tremendous understanding of how things actually work," Tsitsipas said. 

"I think being able to get in these moments more and more often on the Tour helps you understand, makes you wiser when you're trying to deal with all these problems."

Tsitsipas, who could face Open Sud de France champion Jannik Sinner in the next round, ensured there would be no curse of the top seed in Rotterdam, where the favourite had lost their first match in two of the last three editions.

On both occasions (2020 and 2021), that was Medvedev, but the former world number one fought from a set down to beat Alejandro Davidovich Fokina 4-6 6-2 6-2.

World number 10 Hubert Hurkacz also had to battle against a Spaniard in the form of Roberto Bautista Agut. The fifth seed needed three hours to win 7-5 6-7 (7-9) 7-6 (7-4) and tee up an encounter with Grigor Dimitrov. 

Alexander Zverev defeated Soonwoo Kwon in straight sets to book his progress, while Gijs Brouwer got the better of Marc-Andrea Huesler.

Yoshihito Nishioka made it eight wins from his first 10 matches this year after defeating Oscar Otte 6-3 0-6 6-4 in Monday's opening round at the Delray Beach Open.

Nishioka was the highest seed in action on the first day of the tournament, and he had his back up against the wall after failing to win a game in a troubling second set, but produced three breaks of serve in the back-and-forth decider.

Meanwhile, Ecuador's Emilio Gomez earned a shot at top seed and world number seven Taylor Fritz after advancing 7-6 (7-3) 6-4 against Taiwan's Tung-lin Wu.

Portugal's Nuno Borges continued his winning run after earning his spot through the qualifiers, eliminating America's Steve Johnson 6-4 3-6 6-4, but the crowd got something to cheer for when the USA's Denis Kudla got the better of Australia's Jordan Thompson 3-6 6-4 7-6 (7-2).

Further south at Argentina's Buenos Aires Open, Serbia's Laslo Djere booked a blockbuster showdown against world number two Carlos Alcaraz after repelling the challenge of Italy's Fabio Fognini 6-4 6-4.

Argentinian Pedro Cachin put on a show for his hometown fans with a 7-6 (7-2) 6-4 victory over Brazil's Thiago Monteiro, but Cachin's compatriot Guido Pella had less success with a 6-4 7-5 defeat at the hand of Spain's Jaume Munar.

Pablo Carreno Busta was a surprise first-round casualty at the Rotterdam Open after falling to Richard Gasquet on Monday.

World number 16 Carreno Busta, the seventh seed at the ATP 500 event in the Netherlands, took the first set with ease but fell to a 2-6 7-6 (7-2) 6-2 defeat against Frenchman Gasquet.

Veteran Gasquet, ranked 45th in the world, will next meet Stan Wawrinka after the Swiss overcame Alexander Bublik in dominant fashion with a 7-6 (7-5) 6-4 triumph.

Grigor Dimitrov recorded a 6-1 6-3 victory over Aslan Karatsev in just 59 minutes to set up a potential second-round tie with fifth seed Hubert Hurkacz, who must first get past Roberto Bautista Agut.

Qualifier Gregoire Barrere was another straight-sets winner, defeating David Goffin 6-0 7-6 (7-3).

The Frenchman, who is ranked 71st in the world, could meet third seed Felix Auger-Aliassime in the next round if the Canadian overcomes Italy's Lorenzo Sonego.

Argentina's Sebastian Baez tasted success in his home country on Sunday as he defeated Federico Coria 6-1 3-6 6-3 in the Cordoba Open final.

In the fourth ATP Tour final of his career, Baez secured his second title, showing a slight edge both in his service game and with his returns.

He rattled through the first set in just 31 minutes, winning 17 of his 20 total service points (85 per cent), while Coria could only convert at a 48 per cent rate (11 of 23).

Coria tightened things up in the second set and turned the tide, winning 81 per cent of points on his serve while Baez plummeted to 61 per cent, not allowing a single break point opportunity.

Each player created two break point chances in the deciding set, and while Coria failed to convert either, Baez got the job done at the first attempt, jumping out to an early lead and serving it out the rest of the way.

Coria shot himself in the foot with five of the six total double faults, while Baez served the only ace of the match.

The 22-year-old Baez, who entered the contest ranked 47th in the world, will now climb into the top 40 as he edges closer to his career-best ranking of 31st.

Wu Yibing triumphed in an extraordinary final against local hero John Isner at the Dallas Open to become China's first winner of a singles title at ATP tour level in the Open Era.

Isner served 44 aces but still lost, with the 37-year-old going down 6-7 (4-7) 7-6 (7-3) 7-6 (14-12) in a match that saw neither player break serve at any point, climaxing in a marathon tie-break.

Former world number eight Isner was chasing a 17th singles title, and a first at an indoor tournament, and he saw a match point slide by at 6-5 in the second set.

Wu resisted one of the best serves in tennis history and took the match all the way. The first 22 points of the third-set tie-break went with serve, before Wu hit a super backhand winner to interrupt the sequence. Incredibly, Isner won the next rally to bring it back on serve, but the match then got away from him, and a stray forehand from the American gave Wu the title.

Dallas resident Isner, famed for his 11 hours and five minutes win over Nicolas Mahut at Wimbledon in 2010, featuring a 70-68 final set, said of this loss: "That kind of stunk for me."

Wu said: "It's a very tough match today. I'm not even moving when he serves. I made history here for my country. I'm very proud of myself."

There is guaranteed to be an Argentine winner of the Cordoba Open on Saturday, while Taylor Fritz was stunned in Dallas.

Federico Coria, seeded sixth, overcame reigning champion and 2021 runner-up Albert Ramos-Vinolas 6-4 7-6 (7-2) after over two-and-a-half hours of action.

The world number 67, who is into his second ATP Tour-level final and is set to rise into the top 50 of the rankings, has dropped just a single set in the tournament.

Sebastian Baez, eight years Coria's junior, is aiming for his second title after winning in Estoril last year.

The 22-year-old fourth seed defeated Hugo Dellien 6-4 6-4.

This will be the fourth singles final of Baez's career, though his first on home soil.

"It means a lot, but [it brings] confidence," said Baez.

"I have my people here, my friends, my family, everything, so that is a big motivation for me."

While Coria and Baez have just five previous final appearances between them, John Isner advanced to a 31st Tour-level showdown of his career as he beat fellow American J.J. Wolff at the Dallas Open.

Playing in his home city, 37-year-old Isner came from behind to prevail 3-6 7-5 7-6 (7-4).

Isner offered up eight break points, but saved seven of them to frustrate Wolff.

"I saved a lot of break points with unreturnable serves," Isner said. "Without that I would have been dusted off the court 6-3, 6-4. I'm of course very fortunate to have that weapon in my pocket, and I needed every bit of it today.

"It was an absolute battle, so I'm pretty tired. But I'm absolutely ecstatic to be in the final tomorrow here in Dallas."

Asked how he was faring up after his long tussle with Wolff, Isner quipped: "Truthfully, it feels terrible right now. I'm 38 in April. It's not getting any easier. I started off a little slow, a little sluggish, but in the third set I actually felt the best I felt the whole match.

"I had a lot of adrenaline there at the end and I was able to hold my nerve and win. Right now the name of the game is recovery."

Isner will be the favourite in the final, after top seed Fritz surrendered a lead in a 6-7 (3-7) 7-5 6-4 loss to Wu Yibing.
