Gianluca Mager upset Dominic Thiem and then moved within reach of a maiden ATP Tour final as rain continued to impact the Rio Open.

Down a set when forced off on Friday, top seed Thiem failed to stave off a quarter-final loss once play resumed on Saturday.

Italian qualifier Mager turned his overnight advantage into a 7-6 (7-4) 7-5 victory before again taking to the court later in the day for his semi-final.

The 25-year-old's opponent, lucky loser Attila Balazs, earlier beat Pedro Martinez 2-6 6-4 6-2 but was left clinging onto a place in the tournament when the rain returned, the Hungarian trailing 7-6 (7-4) 3-3 against Mager.

The winner will likely face Cristian Garin in the final after the Chilean third seed opened up a 6-4 4-4 lead over Borna Coric in the other postponed semi-final.

Poor conditions also interrupted the Delray Beach Open, where Milos Raonic was unable to get underway against Reilly Opelka.

The big servers had their semi-final rescheduled for Sunday and will compete for a spot in the decider against Yoshihito Nishioka, who battled from a set down to defeat Ugo Humbert 1-6 6-4 6-0.

Nishioka has reached the final despite dropping the opener in three of his four matches at the ATP 250 event.

"After the first set I just figured out how to play against him and just kept trying to do it and then it worked," he said, as quoted by the ATP Tour.

"If I lose the first set it's okay, I just figure out how he's going to play, how I have to play against him and then from the second set I say, 'Okay, let's do it this way.'"

Felix Auger-Aliassime is into a second successive ATP Tour final after seeing off Gilles Simon in straight sets in the Open 13 Marseille semi-final and he will face defending champion Stefanos Tsitsipas for the title.

Second seed Tsitsipas was in impressive form as he dispatched Alexander Bublik in the day's first match, running out 7-5 6-3 victor to reach the final of the tournament for a second year in a row.

The Greek continued his run of not dropping a set at the competition since a first-round defeat to Nicolas Mahut two years ago, racking up a 14th successive win in Marseille.

Tsitsipas was particularly devastating on his own serve in the second set, dropping just a single point, and he was delighted to be able to keep Bublik under control.

"I tried to stay in the match as much as possible and play each point individually," he said, according to quotes on the ATP Tour website. "I know he can be [Bublik] quite unexpected.

"You don't know what to expect. I didn't know what to expect from today's opponent. I am really happy with myself that I found a balance and I didn't panic when things got tight.

"That is a great attitude that I put out on the court. It keeps getting better and better."

Auger-Aliassime will be hoping to go one better than he did in Rotterdam last week, having lost in the final of that event to Gael Monfils.

The Canadian did not have it all his own way against Simon, who eliminated top second Daniil Medvedev in the last round, but Auger-Aliassime showed admirable resilience to claim a double break in the first set after losing his own serve early on.

Simon took the second set to a tie-break, but he rarely appeared to be in the conversation at that stage, with Auger-Aliassime eventually winning 7-5 7-6 (7-2).

Simona Halep clinched her 20th career WTA title and first of 2020 as she overcame Elena Rybakina to win the Dubai Tennis Championship in thrilling fashion.

World number two Halep had to come from a set down against Rybakina, who put in a wonderful display and came within a break of securing her second title of 2020.

But the 20-year-old ultimately fell short in a final-set tie-breaker as Halep triumphed 3-6 6-3 7-6 (7-5) after two hours and 29 minutes on Saturday.

Halep, a Dubai champion in 2015, saved a break point in just the second game of the match but could not keep Rybakina at bay when the next opportunity came, going long in the sixth to fall behind.

Rybakina saw off two late openings to claim the set, only for Halep to make a brilliant start to the second and soon secure a trio of opportunities, breaking to love when Rybakina failed to pick out the left corner of the court.

Halep was made to work to consolidate the break but then had another two break points in the next game.

However, she passed up both opportunities, allowing Rybakina to roar back and break to love, with Halep signalling for her coach after going wide at the end of the rally.

Halep got the motivation she needed and chances came thick and fast in a mammoth game, which she eventually claimed en route to levelling the match when Rybakina slowed and a fourth break point was taken.

Momentum in the decider similarly swung back and forth, with Rybakina in control when Halep double-faulted before that advantage was immediately cancelled out.

A stunning volley put Rybakina 5-4 up, but Halep rallied to hold serve before breaking in the next game to take a 6-5 lead.

Yet Rybakina was not beaten and, at the second attempt, broke serve to force the tie-break.

Rybakina squandered the chance to take a 6-4 lead in the tie-break on her own serve, though, and Halep duly took advantage, with an overhit return handing the Romanian her second triumph in Dubai.

Top seed Dominic Thiem trails by a set and a break in his quarter-final against qualifier Gianluca Mager after the Rio Open was washed out for the day.

Rain wreaked havoc in Rio, where only two quarter-final matches were completed at the ATP 500 tournament on Friday.

Thiem's back is against the wall, with the Australian Open runner-up and world number four down 7-6 (7-5) 2-1 against Mager – who is featuring in his first ATP Tour quarter-final.

Lucky loser Attila Balazs and qualifier Pedro Martinez were also playing when the rain returned in Brazil, with the latter leading 6-2 2-2.

Cristian Garin managed to win through to the semi-finals after the third seed claimed his seventh successive victory by rallying past Federico Coria 2-6 6-3 7-5.

Next up for Garin is fifth seed Borna Coric, who defeated Lorenzo Sonego 7-6 (7-5) 6-3 on the Brazilian clay.

At the Delray Beach Open, second seed Milos Raonic and fellow big server Reilly Opelka will meet in the semi-finals.

Raonic beat Steve Johnson 7-6 (8-6) 6-3 and 2019 New York Open champion Opelka took down Kwon Soon-woo 6-3 6-4 at the ATP 250 event.

"It's going to be tough. He gets a lot of free points on his serve and you've got to make him play," Raonic said.

"You can't just make him play though because he goes for it from the centre of the court. You've got to move in, you've got to find a way to be aggressive."

Elsewhere, Yoshihito Nishioka overcame teenager Brandon Nakashima 3-6 7-6 (7-5) 6-4 and sixth seed Ugo Humbert eased past 2018 winner Frances Tiafoe 6-1 6-2.

Simona Halep cruised into her first final of the year after a devastating 6-2 6-0 semi-final defeat of American qualifier Jennifer Brady at the Dubai Tennis Championships.

Top seed Halep came through a testing quarter-final with Aryna Sabalenka, but her last-four match was significantly more straightforward on Friday.

Halep blitzed through the encounter in just 62 minutes, the 2015 champion appearing way more at ease than in the pair's first-round clash at the Australian Open in January, when Brady succumbed 7-6 (7-5) 6-1.

World number two and two-time grand slam champion Halep faced only two break points in the entire match and she saved both, while she also hit 16 winners to eight unforced errors in a performance she felt was almost perfect.

"It's fun when you feel the ball and when you can do anything you want," Halep said. "Today it was one of those days, I could open the court easily. I felt like every time I hit the ball, I feel it.

"It's always a nice opportunity and privilege to play the last match of the tournament. I play for another trophy, so I'm relaxed. I'm focused. I really want it."

Elena Rybakina will be Halep's next opponent, with the Kazakh securing progress to a fourth final already this year.

Rybakina showed her resilience to come through a gripping duel with eighth seed Petra Martic, saving set points in both sets before eventually winning 7-6 (7-5) 7-6 (7-2).

The 20-year-old has already beaten Australian Open champion Sofia Kenin and former world number one Karolina Pliskova in Dubai, and now she is aiming for the biggest scalp of the lot – and Halep knows she will need to be aggressive to upset the upstart's rise.

"It's amazing what [Rybakina's] done already this year," Halep added. "I saw her a little bit during some matches.

"She has a big serve. I have to pay attention on my return and to be like today: confident, aggressive if there is a chance, just fighting. It's the best thing to do now."

Daniil Medvedev's run of poor results continued at the Open 13 Marseille as he suffered a heavy straight-sets defeat to Gilles Simon.

Top seed Medvedev looked to have put his shock loss to Vasek Pospisil in Rotterdam behind him when he beat teenager Jannik Sinner in three sets to reach the last eight in the south of France.

However, he lasted just 67 minutes on court as Simon won their quarter-final in a 6-4 6-0 rout, racking up his 29th victory in Marseille, the most he has claimed at any ATP Tour event.

Simon's win sets up a semi-final with Rotterdam finalist Felix Auger-Aliassime, the 19-year-old defeating Egor Gerasimov 7-5 6-2.

Pospisil was unable to earn a second shock victory in as many weeks, losing to world number six Stefanos Tsitsipas 7-5 6-3.

Auger-Aliassime will be the sole Canadian in the last four, with Denis Shapovalov joining Pospisil exiting at the quarter-final stage.

Fourth seed Shapovalov won the second set against Alexander Bublik, but was unable to complete a comeback after losing the first and was eventually defeated 7-5 4-6 6-3.

Kevin Anderson is set to miss the first two ATP Masters events of the season after he underwent surgery on a knee injury.

Former world number five Anderson – a US Open and Wimbledon finalist in 2017 and 2018 respectively – confirmed the news on his official Twitter account on Friday.

The 33-year-old, now ranked at 121, slumped out in the second round of the Australian Open in January before succumbing to Jason Jung in the round of 32 at the New York Open this month.

Anderson will now miss the Mexico Open, where he is a two-time finalist, along with the Masters events at Indian Wells and Miami and seems set to face a race against time to be fit for the French Open in May.

He has confirmed the injury to his right knee was sustained during off-season training in December, with scans in Australia confirming a medial meniscus tear.

"It is beyond difficult and frustrating to have to deal with this, after the setbacks I had last year," Anderson posted on Twitter. "But I know it's the right decision for me to get back where I want to, and rest assured I will do everything in my power to get there."

Dominic Thiem survived another test to reach the Rio Open quarter-finals, while Milos Raonic's run at Delray Beach continued on Thursday.

Thiem, playing his first tournament since reaching the Australian Open final, was pushed by Jaume Munar before winning 6-7 (5-7) 6-3 6-4 on the clay in Brazil.

The Austrian top seed, who won the ATP 500 event in 2017, needed two hours, 41 minutes to advance, having also dropped a set in his opener.

Thiem will face Gianluca Mager in the quarter-finals after the Italian qualifier's 6-3 7-6 (7-5) victory over Joao Domingues.

Borna Coric moved into the last eight courtesy of a 6-3 1-6 7-6 (7-5) win against wildcard Thiago Seyboth Wild.

The fifth seed will meet Lorenzo Sonego, who upset second seed Dusan Lajovic 7-6 (7-5) 7-6 (7-5).

At the Delray Beach Open, Raonic – the 2017 runner-up – served 11 aces in a 7-5 6-3 win over Cedrik-Marcel Stebe that sent him into the quarter-finals.

Steve Johnson awaits the Canadian after overcoming 2017 champion Jack Sock 6-4 5-7 6-1.

Frances Tiafoe, the 2018 winner, and Ugo Humbert set up a last-eight meeting with straight-sets victories over Tommy Paul and Miomir Kecmanovic respectively.

Open 13 Marseille top seed Daniil Medvedev got his tournament off to a fine start as he came from behind to defeat NextGen champion Jannik Sinner.

The 18-year-old Sinner claimed the first top-10 scalp of his career when he beat David Goffin last week, but he did not have enough to hold on against Medvedev.

After world number five Medvedev was brushed aside in a 25-minute first set, the Russian claimed two vital breaks in the second set before taking the decider for a 1-6 6-1 6-2 victory.

Medvedev will next take on Gilles Simon - a Marseille champion in 2007 and 2015 - after the Frenchman overcame Aljaz Bedene 7-6 (8-6) 6-4 to reach the quarter-finals.

Meanwhile, Goffin suffered another upset, going down 6-4 7-6 (7-5) to Belarusian qualifier Egor Gerasimov.

Gerasimov's next opponent, Felix Auger-Aliassime, overcame Pierre-Hugues Herbert in a thrilling encounter, with the youngster coming out on top 6-0 6-7 (6-8) 7-6 (11-9).

Auger-Aliassime's Canadian compatriot Denis Shapovalov also made the last eight as 17 aces helped him defeat two-time finalist Marin Cilic 6-4 4-6 6-2, with the world number 15 to meet Alexander Bublik next.

Simona Halep survived a scare against Aryna Sabalenka as she fought back from a set down to progress into the Dubai Tennis Championships semi-finals.

Halep, appearing for the first time since a run to the last four at the Australian Open, lost to Sabalenka in their most recent meeting - in Adelaide in January - but had won her prior two encounters with the world number 13.

Despite trailing in the first set, the world number two rallied in the second thanks to three breaks of serve, before cruising in the decider to wrap up a 3-6 6-2 6-2 win over her Belarusian opponent.

The Romanian, a Dubai champion in 2015, will now go up against Jennifer Brady, whose run of upsets continued as she overcame Australian Open finalist Garbine Muguruza to claim her third straight top-20 triumph.

Having already knocked out third seed Elina Svitolina and Marketa Vondrousova in previous rounds, Brady moved into the semis with a 6-7 (5-7) 6-3 6-4 win.

It is the first time in Brady's career that the American has made it into the last four of a WTA Premier event, though she was not fully satisfied with her performance.

"I wasn't feeling my best," she said in quotes reported by the WTA's official website. "Maybe I didn't play my best tennis, but I just found a way to stay in there, compete and come out on top."

The other semi-final will see Elena Rybakina, whose fine run continued with a win over Karolina Pliskova, meet Petra Martic.

Dubai debutant Rybakina has started 2020 in fine form and dispatched world number three Pliskova on Thursday, completing a 7-6 (7-1) 6-3 success in one hour and 41 minutes.

It means Rybakina has made her fourth semi-final in five tournaments so far this year, with a tie against Martic - who beat Anett Kontaveit 7-6 (7-4) 6-1 - her reward.

Roger Federer will miss the French Open after undergoing knee surgery on Wednesday, the 20-time grand slam champion has confirmed.

The 20-time grand slam champion was due to play in his second tournament of the year at the Dubai Tennis Championships next week after losing to Novak Djokovic in the semi-finals of the Australian Open last month.

Federer, 38, revealed on Thursday that he has been troubled by an issue with his right knee and underwent an arthroscopic operation in his native Switzerland, which should enable him to make a full recovery.

The world number three will sit out the second major of the year at Roland Garros in May, but expects to be back for the grass-court season.

Federer posted on Twitter: "My right knee has been bothering me for a little while.

"I hoped it would go away, but after an examination, and discussion with my team, I decided to have arthroscopic surgery in Switzerland yesterday.

"After the procedure, the doctors confirmed that it was the right thing to have done and are very confident of a full recovery.

"As a result, I will unfortunately have to miss Dubai, Indian Wells, Bogota, Miami and the French Open. I am grateful for everyone's support.

"I can't wait to be back playing again soon, see you on the grass!"

American teenager Brandon Nakashima reached the Delray Beach Open quarter-finals, while Cristian Garin moved through to the last eight of the Rio Open.

Competing in his debut ATP Tour tournament, 18-year-old wildcard Nakashima defeated British qualifier Cameron Norrie 7-5 6-2 on Wednesday.

Nakashima, who is coached by 1987 Wimbledon champion and two-time Australian Open runner-up Pat Cash, is the event's youngest quarter-finalist since Kei Nishikori won the tournament as an 18-year-old in 2008.

"I always knew that I had the game to compete with these high-level pros. I just had to have the right opportunities," said Nakashima, who will face Yoshihito Nishioka after the Japanese blitzed Noah Rubin 6-1 6-2.

"I was just hoping to play a good first-round match here, but after winning these two matches, I have a lot of confidence in my game now… Hopefully I can keep it going."

Reilly Opelka – the fourth seed – dismantled Mackenzie McDonald 6-3 6-4 and Kwon Soon-woo prevailed 6-4 3-6 7-6 (7-0) against Ryan Harrison.

At the Rio Open, third seed Garin beat Federico Delbonis 6-4 6-3 en route to the quarters in Brazil.

Garin, who claimed the Cordoba Open title almost a fortnight ago, hit 22 winners to earn a meeting with Federico Coria after the Argentinian's 6-4 4-6 6-4 victory over Carlos Alcaraz.

Elsewhere, lucky loser Attila Balazs rallied past Thiago Monteiro 1-6 6-1 6-4 and Pedro Martinez trumped fellow Spaniard Pablo Andujar 6-1 6-4.

Stefanos Tsitsipas started the defence of his Open 13 Marseille title with a straight-sets victory over Mikael Ymer to reach the quarter-finals.

Tsitsipas has made a disappointing start to the season, but took just 71 minutes to dispatch Ymer 6-1 6-3 on Wednesday.

The ATP Finals champion lost just three points on his first serve and did not face a solitary break point in an emphatic win.

Second seed Tsitsipas will face Vasek Pospisil in the last eight following the Canadian's 6-3 6-4 defeat of eighth seed Hubert Hurkacz.

Sixth seed Benoit Paire made a surprise exit in his homeland, going down 3-6 6-4 6-4 to Alexander Bublik in the second round.

It was anything but plain sailing for Felix Auger-Aliassime, who saved two match points before getting past Stefano Travaglia 6-7 (3-7) 7-6 (8-6) 6-3.

Auger-Aliassime's second-round opponent will be Pierre-Hugues Herbert, a 7-6 (7-4) 6-4 victor in his match against Mikhail Kukushkin. 

Egor Gerasimov also reached round two by knocking out fellow qualifier Dennis Novak.

Top seed Simona Halep saved a match point in a gripping battle with Ons Jabeur before sealing her place in the quarter-finals of the Dubai Tennis Championships.

Halep was on the brink of a surprise defeat to the in-form world number 45, but hung in there to win a thriller 1-6 6-2 7-6 (9-7) on Wednesday.

The two-time grand slam champion and Jabeur were given great backing from passionate Romanian and Tunisian supporters in a pulsating contest that swung one way and the other.

Halep appeared destined to complete the turnaround with ease when she led 3-0 in the final set, but the tenacious Jabeur was relishing the battle and showed great spirit to take the upper hand at 6-5.

The unseeded Jabeur was broken to love when serving for the match, though, and a double-fault gifted 2015 champion Halep a 4-2 lead in the tie-break, yet there was more drama to come.

Jabeur fended off three match points to earn one of her own, but Halep showed her grit to win the next two points before her gutsy opponent drilled a forehand long to end a tense two-hour contest.

Halep will face Aryna Sabalenka in the last eight after the seventh seed defeated Elise Mertens 6-4 6-3.

Australian Open runner-up Garbine Muguruza advanced with a hard-fought Veronika Kudermetova, winning 7-5 4-6 6-4 two days after knocking out the returning Kim Clijsters.

Elena Rybakina, a three-time finalist this year, got the better of Katerina Siniakova for the second successive week, a 6-3, 6-3 victory setting up a meeting with Karolina Pliskova.

Second seed Pliskova lost just three games in emphatic defeat of Kristina Mladenovic, while Petra Martic, Jennifer Brady and Anett Kontaveit were also victorious.

Dominic Thiem resumed his season with a first-round win at the Rio Open, while Jack Sock finally ended his wait for another victory.

Thiem, last in action in an Australian Open final loss to Novak Djokovic, returned with a 6-2 4-6 6-1 victory over wildcard Felipe Meligeni Alves on Tuesday.

The 2017 champion of the ATP 500 event played on clay in Brazil, top seed Thiem grabbed two breaks of serve in the deciding set.

Having started 2020 with four losses in five matches, Borna Coric found a victory by overcoming Juan Ignacio Londero 7-6 (7-5) 7-5.

Dusan Lajovic joined Thiem and Coric as the three seeds to win, but two fell in the opening round.

Casper Ruud, coming off a title win at the Argentina Open, went down to qualifier Gianluca Mager 7-6 (7-4) 7-5.

Guido Pella, the 2016 runner-up, was edged by Thiago Monteiro 5-7 6-4 7-6 (7-3) after just over three hours.

At the Delray Beach Open, Sock claimed his first non-Laver Cup singles win since late 2018.

The American 2017 champion, a wildcard, battled past last year's winner Radu Albot 3-6 6-3 7-6 (7-2), saving a match point in the final set and breaking down in tears following his victory.

Canadian second seed Milos Raonic brushed past lucky loser Denis Istomin 6-2 6-2 and Reilly Opelka served 20 aces in a 6-7 (5-7) 6-4 7-6 (7-4) victory over Ernests Gulbis.

Ugo Humbert, the French sixth seed, battled through, while third seed Taylor Fritz fell to qualifier Cameron Norrie 6-4 6-7 (4-7) 6-4.
