Felix Auger-Aliassime finally won a first ATP Tour title after impressively dealing with Stefanos Tsitsipas in straight sets in Rotterdam on Sunday.

The Canadian had lost all of his previous eight finals on the tour, not even clinching a set in any of them, but he found the winning formula this time as he beat Tsitsipas 6-4 6-2.

Auger-Aliassime made an emphatic start, breaking Tsitsipas in the very first game and from that point there was no looking back.

The 21-year-old's aggressive style of play had Tsitsipas on the back foot almost throughout and, after claiming the first set, he saw things out with admirable confidence.

He raced into a 5-1 lead in the second set and there were never any signs of nerves on his part, as he avoided facing a single break point over course of the full match.

Auger-Aliassime, who was beaten by Gael Monfils in the 2020 Rotterdam final, said: "It has not been the smoothest road since my first final three years ago.

"It is an amazing day for me to get my first title and especially here. I played my first ATP main draw here a couple of years ago [in 2018], so it is right I won my first title here.

"I have a lot of good memories playing here in front of you, so thank you for making it a special week for me that I will remember for the rest of my life.

"It is the happiest day of my career, and hopefully it is the first of many to come."

Tsitsipas accepted he lost to the better player on the day, bemoaning his struggles when serving.

The world number four won 74 per cent of points on his first serve and 33 per cent on his second – both figures were dwarfed by Auger-Aliassime's 93 per cent and 69 per cent, respectively.

"He played a really good match, producing really good shots and serving well the whole match," Tsitsipas said.

"I wasn't able to serve well at all today. He played very well."

Anett Kontaveit clinched the WTA St Petersburg Ladies Trophy title, fighting back to win an enthralling three-set final against world number seven Maria Sakkari on Sunday.

The Estonian, ranked ninth in the world, won her sixth career singles title after recording a tense 5-7 7-6 (7-4) 7-5 win over her Greek rival, in a clash between the tournament's top two seeds.

The victory means Kontaveit leads Sakkari for head-to-head victories, winning seven of their 13 meetings to date, and stretched the champion's remarkable run of indoor wins to 20 matches.

She was made to suffer before recording her first title of 2022, winning the eagerly awaited clash after a gruelling three hours of tennis.

Sakkari struck the first blow, winning a tense opening set as she targeted a first WTA 500 title of her career.

Kontaveit responded strongly and forced a decider by winning a tight second via a tie-break.

Greek top seed Sakkari found herself one service game from victory after a strong start to the third set, before Kontaveit's counter-attack arrived.

Kontaveit rallied after going 5-3 down by registering consecutive breaks, before comfortably seeing out her final service game, and has now won five of her last six singles finals.

The top two seeds Casper Ruud and Diego Schwartzman will face off in the Argentina Open final after the latter won two matches on Saturday to progress at his home event.

The Argentine world number 14 had to overcome countryman Francisco Cerundolo 6-3 2-6 5-7 earlier on Saturday after their quarter-final had been interrupted by rain on Friday evening.

The match was tied at 1-1 in the third set when rain intervened, with Schwartzman triumphing when play resumed to earn a semi-final date with third seed Lorenzo Sonego.

Schwartzman would later beat Sonego 7-5 3-6 6-2 in almost three hours on a busy day for the 2020 French Open semi-finalist.

World number eight Ruud progressed with a routine 6-3 6-3 victory over Argentine sixth seed Federico Delbonis.

At the Dallas Open semi-finals, Reilly Opelka and John Isner broke the record for the longest tiebreaker on the ATP Tour since 1990.

Second seed Opelka triumphed over fellow American Isner but it was not easy, winning 7-6 (9-7) 7-6 (24-22).

Opelka sent down 39-21 aces across the match, earning a spot in the final against fourth seed Jenson Brooksby who beat Marcos Giron 6-4 6-7 (4-7) 7-6 (7-5).

Stefanos Tsitsipas will face Felix Auger-Aliassime in the final of the ABN Amro World Tennis Tournament, after they prevailed in hard-fought semi-finals on a day of drama in Rotterdam. 

Top seed Tsitsipas faced a tough test against 20-year-old Czech qualifier Jiri Lehecka, whose dream run had included a shock win over world number 12 Denis Shapovalov.

The world number four was forced to battle back after losing the opening set, eventually beating the main-draw debutant 4-6 6-4 6-2.

Tsitsipas, whose last final appearance saw him blow a two-set lead over Novak Djokovic in the 2021 French Open showpiece, has yet to claim an ATP 500 title during his career, a record which he will now look to set straight against Auger-Aliassime. 

Currently ranked ninth in the world, the 21-year-old had to overcome a stern test of his own against defending champion Andrey Rublev, who sits two places higher in the ATP rankings, to reach the ninth final of his singles career.

After losing a thrilling first set in a tie-break, Auger-Aliassime roared back to claim a 6-7 (5-7) 6-4 6-2 win over the Russian, his first victory over Rublev in three career attempts.

Auger-Aliassime is chasing his first career title, after losing in the final of this same event against Gael Monfils in 2020.

The final will be Tsitsipas and Auger-Aliassime's eighth career meeting. The Greek has won the most recent five, including their only previous meeting on a hard indoor surface, in the final of 2020's Open 13 in Marseille.

Maria Sakkari will face Anett Kontaveit in what seems set to be an enthralling top-10 clash in the final of the St Petersburg Ladies Trophy.

Sakkari, the top seed in the tournament, had to go the distance against Irina-Camelia Begu, with the world number seven eventually prevailing 6-4 6-7 (4-7) 6-4.

That victory took Sakkari three hours and four minutes, as she had to fight back from a break down in the deciding set.

However, she is now into a fourth singles final of her career and has gone one better than her previous best run at St Petersburg, which came in 2020 when she reached the semi-finals.

"It was a very tough match. I think Begu played really, really well," Sakkari said.

"The level of the match was super high. I had to come up with some very tough shots and very physical tennis, but I'm very glad I did it, and I'm super excited to be in the final here."

Second seed Kontaveit awaits in Sunday's final, and the Estonian world number nine should be much fresher after only needing an hour and 11 minutes to see off Jelena Ostapenko 6-3 6-4.

Kontaveit has remarkably now won 19 matches in a row indoors in the longest such sequence since Justine Henin celebrated 22 consecutive victories between 2007 and 2010.

"It was a very competitive match. I really had to bring very good energy to come through on top today," Kontaveit said.

"She's a very aggressive player, so I had to be really ready for her big shots and just be as consistent and take my chances when I could. I felt like I did that really well today."

Sakkari and Kontaveit have met 12 times previously, with each player winning six times.

Casper Ruud will have to overcome another home hopeful if he is to reach the final of the Argentina Open in Buenos Aires.

Top seed Ruud defeated Federico Coria 6-3 6-4 in the last eight on Friday to set up a semi-final against another Argentinian in Federico Delbonis.

Delbonis defeated Fabio Fognini 6-4 6-4 to make his first semi since losing to Pablo Carreno Busta in Hamburg last July.

The 31-year-old has not played an ATP Tour final since winning in Marrakech in 2016.

There will be a home representative remaining in the other half of the draw, too, although his identity is still to be confirmed.

Diego Schwartzman and Francisco Cerundolo were tied in the third set when rain saw play suspended for the day.

The winner of that match will play Fognini's compatriot Lorenzo Sonego, a straight-sets victor against Fernando Verdasco.

At the Dallas Open, there is an all American cast for the semi-finals – but top seed Taylor Fritz is not among those in the last four.

He lost a third-set tie-break to countryman Marcos Giron, whose reward is a match against Jenson Brooksby. Brooksby beat Australia's Jordan Thompson 6-3 6-0.

John Isner breezed through in straight sets and will face Reilly Opelka.

Stefanos Tsitsipas' impressive display of power hitting helped him past Alex De Minaur and into the semi-finals of the Rotterdam Open.

The Greek has yet to win an ATP 500 tournament but is now a step closer to ending that record after overcoming his Australian opponent 6-4 6-4 in a little over 90 minutes.

De Minaur's excellent movement was quelled by Tsitsipas, who hit 19 winners and won 27 of 33 first-serve points (82 per cent).

Speaking after his win, Tsitsipas said: "I took my time, I tried to understand what works for me and what doesn't, and with the right momentum, with the right intention, things kind of paid off. 

"I was able to get ahead in the score, which gave me a lot of confidence, and I think my serve was very good today, it gave me a lot of points and applied a lot of pressure to him."

Czech qualifier Jiri Lehecka is Tsitsipas' surprise semi-final opponent as the world number 137 continued a fine run by defeating Lorenzo Musetti 6-3 1-6 7-5.

There was a sense of deja vu in the later sessions as Andrey Rublev defeated Marton Fucsovics 6-4 6-3.

Rublev defeated the same opponent in the final of the 2021 tournament, and is now one win away from returning to the showpiece match.

Felix Auger-Aliassime is backing up a strong performance at the Australian Open, where the world number nine was beaten by Daniil Medvedev in the quarter-finals.

The Canadian came through a tough encounter against Cameron Norrie 7-5 7-6 (7-4) as he aims to go one better than his runners-up appearance in Rotterdam in 2020.

Maria Sakkari is handling the pressure of playing as top seed in a WTA Tour-level tournament for the first time, as she put herself to within one win of the final at the St Petersburg Ladies Open.

The Greek world number seven saw off a stern test from Elise Mertens on Friday, winning 7-6 (9-7) 6-2 to reach the semi-finals.

Sakkari had to salvage three set points in the opener, but eventually came out on top in the tie-break at the first time of asking.

Even with a comfortable lead in the second set, she failed to take the first three match points on offer, but got the fourth over the line to progress to her first semi-final of the season.

Sakkari, 26, previously reached the St Petersburg semi-final in 2020, where she lost to Elena Rybakina.

"When you're down in the score, you try to play more aggressively and [Elise] was playing really good in the last couple of games," Sakkari explained. 

"She came up with good serves and solid shots from the baseline. I just fought hard."

Next up

Irina-Camelia Begu stands in the way of Sakkari and a place in the final. 

The unseeded Romanian overcame two-time grand slam champion Petra Kvitova in the last 16 and defeated Tereza Martincova 6-4 6-2 in her last-eight tie.

It took just 85 minutes for Begu to secure her place in a fourth semi-final of her career at WTA 500 level or higher, but the first since 2017 in Moscow.

Kontaveit continues remarkable indoor run

World number nine Anett Kontaveit will face Jelena Ostapenko in the other semi-final, after ousting Tokyo 2020 gold medallist Belinda Bencic 7-6 (9-7) 6-2.

After her defeat of Bencic, second seed Kontaveit has now won 18 successive matches at indoor tournaments. She is the first player since Justine Henin in 2010 to go on such a streak.

Last year, the Estonian won titles in Ostrava, Moscow and Cluj-Napoca, which form part of this run.

Ostapenko, meanwhile, beat Aliaksandra Sasnovich 7-6 (7-5) 4-6 6-3 to take her place in the last four. The 2017 French Open champion has only lost to top-10 players so far in 2022 (Paula Badosa and Barbora Krejcikova).

Jenson Brooksby made a winning start to his 2022 season on the ATP Tour as he reached the quarter-finals of the Dallas Open.

Last year's ATP Newcomer of the Year missed the Australian swing after testing positive for COVID-19 and only made his return at the Columbus Challenger at the end of last month.

The world number 54 admitted to feeling a little nervous in his 6-3 3-6 6-3 win over Andreas Seppi, but he said: "I competed well. As an American in the U.S., it was a great crowd. I missed that atmosphere for a few months.

"I thought I stayed pretty calm out there; a good balance of calm and competing, which is always a focus of mine."

Fifth seed Adrian Mannarino enjoyed smoother progress into the quarter-finals, beating Yoshihito Nishioka 6-3 6-1.

Vasek Pospisil saved a match point before coming through 6-7 (3-7) 7-6 (8-6) 6-2 against Jurij Rodionov, setting up a last-eight clash with home favourite John Isner, whose compatriot Reilly Opelka also progressed from a big-serving contest with Cedrik-Marcel Stebe.

At the Argentina Open, Fabio Fognini progressed to his first Tour-level quarter-final since April after battling past Pedro Martinez.

The Italian won 6-4 7-6 (7-5) to secure a meeting with Federico Delbonis, the Argentine having dispatched Pablo Andujar in straight sets.

Delbonis' compatriot Diego Schwartzman also defeated Spanish opposition in the form of Jaume Munar, although the world number 15 was made to work hard for a victory that sent him into a last-eight contest with Francisco Cerundolo.

Schwartzman came through 7-6 (7-2) 7-6 (7-4) in two hours and 23 minutes, eventually closing out the victory with a return winner on his seventh match point.

"I'm very happy because it was tough at the end," Schwartzman said. "He was saving too many match points, winning too many good points at the end of the match and he had the chance to go into the third.

"I think the tie-break, in the beginning, I played better than him. But at the end, he was fighting and he was there."

Andy Murray suffered defeat in the second round of the Rotterdam Open as he fell in straight sets to Felix Auger-Aliassime, while Andrey Rublev and Stefanos Tsitsipas progressed. 

Murray, who triumphed at this tournament in 2009, battled past Alexander Bublik in his opening match but struggled to replicate that form against Auger-Aliassime on Thursday. 

The Scot was never in control against the world number nine, who will face Murray's fellow Briton Cameron Norrie in the quarter-final, as he was downed 6-3 6-4 by the third seed. 

"From the start of the match I was ready and focused and I think that is why I was able to produce a high level from the first point," Auger-Aliassime said on court after his victory.  

"He made me bring out my best tennis and I am really happy with the way I played and that I was able to stay ahead. [To] win in straight sets is a great relief." 

Top seed Tsitsipas, who was a beaten semi-finalist in this event last year, made light work of Ilya Ivashka as he raced to a 6-4 6-1 triumph in just one hour and 11 minutes to tee up a last-eight meeting with Alex de Minaur. 

Reigning champion Rublev cruised past Soonwoo Kwon in similar fashion with a 6-3 6-3 win to secure his seventh straight victory at the ATP 500 tournament. 

Meanwhile, qualifier Jiri Lehecka recovered from a first-set scare against Botic van de Zandschulp to succeed 1-6 6-4 6-4, with Lorenzo Musetti awaiting the Czech in the next round. 

Petra Kvitova crashed out of the St Petersburg Ladies Trophy, but Jelena Ostapenko is safely through to the quarter-finals.

Two-time grand slam champion Kvitova was comfortably beaten in straight sets by Irina-Camelia Begu, with the Romanian winning 6-4 6-0 in just one hour and nine minutes.

The effectiveness of the first serve was the main difference-maker, with Begu winning 73.1 per cent of her first-serve points, while Kvitova – who has 28 singles titles to her name in contrast to her opponents' four – could only manage 50 per cent.

Begu was set to face the winner of Tereza Martincova's tie with Elena Rybakina, but the latter withdrew because of illness.

Seventh seed Ostapenko made light work of Andrea Petkovic as she beat the German 6-1 6-2 in just 58 minutes, helped largely by winning 85.3 per cent of her first serves, as well as saving all five of the break points she offered up.

Ostapenko has now won two of her four meetings with Petkovic and will next face Aliaksandra Sasnovich, who eased to a 6-2 6-3 victory over Jaqueline Cristian.

Casper Ruud began his Argentina Open title tilt with an impressively routine defeat of Roberto Carballes Baena.

The Norwegian, who is the top seed, saw off his opponent 7-6 (7-2) 6-3 to set up a quarter-final clash with home hopeful Federico Coria, who defeated Dusan Lajovic 4-6 7-5 6-4.

Ruud was taking to the court for the first time since being in ATP Cup action in early January, with ankle injury ruling him out of the Australian Open.

But on the scene of his maiden ATP title win in 2020, Ruud – who has won five tournaments since – looked in good shape.

"I feel, obviously, very good in Buenos Aires. I was a bit nervous coming back because it's the first time I have to defend a title," he said.

"Everything is a bit different since two years ago. When I won here it was a surprise. I was young.

"[This] was a good start. First time playing on clay in six months, so everything is a bit new again.

"Of course, I prefer to play on clay, but it takes some time to get used to the court and playing points."

Third seed Lorenzo Sonego also advanced through to the last eight in straight sets, the Italian beating Sebastian Baez 6-3 6-3 to set up a meeting with Fernando Verdasco.

Unseeded Spaniard Verdasco, seeking an eighth career title, progressed thanks to a hard-fought 2-6 6-3 7-5 win over Thiago Monteiro.

At the Dallas Open, John Isner won his opening match on home soil with a 7-6 (7-1) 6-7 (7-9) 7-6 (7-5) victory over Kevin Anderson.

Isner will next take on either Vasek Pospisil or Jurij Rodionov, with the qualifiers scheduled to meet on Thursday.

Marcos Giron and Jordan Thompson are also in the quarter-finals after seeing off Liam Broady and Brandan Nakashima respectively.

Novak Djokovic has been included on the entry list for next month's Indian Wells Open despite the tournament requiring all players are vaccinated against COVID-19.

Last month, the world number one and 20-time grand slam winner was deported from Australia on the eve of the Australian Open after his entry visa to the country was cancelled due to him not being vaccinated against coronavirus.

Djokovic believed he was still eligible to enter the country and compete after testing positive for coronavirus in December and making a full recovery.

The Serbian was subsequently sent home as he lost the legal battle that dominated much of the sports news agenda during the early weeks of 2022.

Djokovic is set to make his return to the court at the Dubai Duty Free Tennis Championships later this month, with vaccination not a requirement.

But it is at Indian Wells, where the five-time champion has been announced as a competitor, prompting curiosity about whether more legal battles await or if Djokovic has since been jabbed.

An Indian Wells statement read: "With health and safety as the tournament's top priority, the BNP Paribas Open will require valid proof of full vaccination to enter the Indian Wells Tennis Garden for the tournament.

"For the second consecutive year, the BNP Paribas Open has partnered with CLEAR, the secure identity company, to facilitate the implementation of the venue's mandatory vaccination policy ahead of the 2022 tournament.

"The guidelines for the players are governed by the protocols established by their respective governing bodies, the WTA and ATP, as well as any restrictions established by the United States of America in regard to the vaccination status of international travellers entering the country."

Images of Djokovic do not appear any of the tournament's build-up social media posts nor the website's promotional announcement, while his entry-list inclusion is little more than a footnote – but, crucially, it does include him.

The statement continued: "A power-packed line-up of ATP top-10 players will join [Rafael] Nadal in looking to put together a breakthrough performance in Tennis paradise.

"2021 US Open champion and 2022 Australian Open finalist Daniil Medvedev (world no. 2), 2021 ATP Finals winner Alexander Zverev (world no. 3), and 2021 French Open finalist Stefanos Tsitsipas (world no. 4) will each be in search of their maiden title in the desert.

"Reigning BNP Paribas Open champion Cameron Norrie (world no. 13) will look to replicate his extraordinary 2021 title run, in which he won his first Masters 1000 crown.

"World no. 1 and five-time Indian Wells champion Novak Djokovic is also on the tournament entry list."

Andy Murray set up a second-round clash with Felix Auger-Aliassime at the Rotterdam Open, but fourth seed Hubert Hurkacz was stunned by Lorenzo Musetti. 

Former world number one Murray secured an impressive 7-6 (8-6) 6-4 victory over Alexander Bublik, who entered the tournament on the back of the biggest win of his career over Alexander Zverev in the Montpellier final last week. 

Murray stopped the Kazakh serving out the opening set with a crucial break and appeared in fine form as he closed out the win. 

"There were some tough moments in the first set for both of us. I just managed to come through at the end of it. Some great returns off some big second serves from him at the end and I did a good job," said Murray. 

"It’s not easy playing against someone like that, huge serves, a lot of drop shots and you’ve got to keep your focus and I did that well." 

Up next for Murray is Australian Open quarter-finalist and third seed Auger-Aliassime, who came from a set down to beat qualifier Egor Gerasimov 3-6 6-2 6-2. 

"[Auger-Aliassime] started the year pretty well and is one of the best young players just now," said Murray. "I'll need to be on my game if I want to beat him, but it's a great test for me and we'll see what happens out there." 

Musetti advanced to the quarter-finals after a 6-3 5-7 6-4 triumph over Hurkacz, dropping just one point on his first serve in the decisive set. 

Cameron Norrie defeated Karen Khachanov 6-4 7-6 (7-5) to reach the last eight, while Alex De Minaur was also a 7-6 (8-6) 1-6 6-4 victor against Mackenzie McDonald in the second round.

Maria Sakkari and Anett Kontaveit were among the big names to cruise through to the quarter-finals of the St Petersburg Ladies Trophy on Wednesday.

Top seed Sakkari faced Ekaterina Alexandrova in the second round and recorded a routine 6-2 6-4 triumph as she looks to bounce back from a fourth-round exit at the Australian Open. 

The Greek will next face a difficult contest with Elise Mertens, who needed three sets to see off the challenge presented by Petra Martic and seal a 6-4 3-6 6-2 success. 

Second seed Kontaveit recorded a 6-4 7-5 victory over Romania's Sorana Cirstea to set up a tantalising meeting with Belinda Bencic after the Swiss downed Kaja Juvan 6-1 7-6 (7-2). 

World number 12 Elena Rybakina, meanwhile, needed less than an hour to record a straight-sets victory over Varvara Gracheva, booking an encounter with Tereza Martincova in the round of 16.
