Stefanos Tsitsipas saw his interest in the Paris Masters ended at the earliest opportunity in a second-round defeat to Ugo Humbert after three tie-breaks on Tuesday.

Second seed Tsitsipas had a bye through the first round before starting his run against Humbert, but a 7-6 (7-4) 6-7 (6-8) 7-6 (7-3) reverse means the Greek can already turn his attention towards defending his ATP Finals title.

A topsy-turvy affair was ultimately settled in Humbert's favour, although the 22-year-old looked to have ceded the initiative late in the second set.

Having battled back from a break down to take the opener, Humbert squandered three match points in the second tie-break in a remarkable collapse.

But the world number 34 - enjoying a fine year with breakthrough titles in Auckland and Antwerp - steadied himself again at the start of the decider.

Humbert once more let a lead slip but this time recovered to see out yet another breaker and claim his second career top-10 win before hailing his own mental fortitude after a marathon match lasting three hours and 17 minutes.

"I'm super happy, super proud of myself," he said. "I was mentally very strong to win this match against Tsitsipas, one of the best players in the world."

Tsitsipas added: "His serve was very consistent. Despite having opportunities where he would serve second serves [and] I could come in, be more aggressive, it didn't seem as easy as I had it planned in my head."

Humbert was one of four Frenchmen to win on Tuesday, although fellow home hopefuls Gilles Simon and Corentin Moutet exited the tournament, the latter's positive COVID-19 test granting Marin Cilic - Humbert's next opponent - a walkover.

Tsitsipas' loss came after the departure of eighth seed David Goffin, beaten in straight sets by Norbert Gombos.

Kevin Anderson advanced to face Daniil Medvedev after Laslo Djere retired, while John Millman failed to build on his first ATP Tour title win in Astana as he lost to Miomir Kecmanovic.

Feliciano Lopez clinched a 7-6 (13-11) 6-1 victory over Filip Krajinovic at the Paris Masters to set up a second-round meeting with world number two Rafael Nadal.

Lopez came through the match against the Serbian, ranked 30th in the world, at the Bercy Arena in 85 minutes on Monday.

He saved six set points in the first-set tie-break before he ruthlessly closed out the second to secure a first meeting with Nadal in five years.

The 39-year-old has beaten his fellow Spaniard in their past two meetings in Cincinnati in 2015 and Shanghai in 2014, although Nadal boasts a better record overall in their head to head with nine wins to Lopez's four.

Borna Coric, seeded 15th, claimed a 7-6 (7-5) 6-1 win over Hungarian qualifier Marton Fucsovics.

Lucky loser Radu Albot saw off 21 aces to edge past Hubert Hurkacz 7-5 6-7 (5-7) 6-4 to seal a meeting with world number eight Andrey Rublev, winner of the Vienna Open on Sunday.

Marin Cilic claimed a 6-0 3-6 6-3 win against Felix Auger-Aliassime, while Alex de Minaur beat Stefano Travaglia 6-4 6-4.

Andrey Rublev won the Vienna Open after a confident 6-4 6-4 victory over surprise contender Lorenzo Sonego to book his place at the ATP Finals in London.

The Russian wrapped up the win at the Wiener Stadthalle in an hour and 19 minutes on Sunday as he clinched his fifth ATP title of the season.

Unheralded Sonego, ranked at number 42 in the world, had reached the final in the wake of a shock quarter-final win over world number Novak Djokovic but could not repeat the feat against a clinical Rublev.

"This tournament is really special for me because my grandma was also Austrian, so I have Austrian blood," Rublev said during the trophy presentation.

Italian Sonego found no way past Rublev's serve as he failed to inflict a single break.

It ensured Rublev ended the tournament without once surrendering his serve in 38 games – becoming the first player to achieve the feat in an ATP tournament since Alex de Minaur reeled off 42 games at Atlanta in 2019.

John Millman has the first ATP Tour title of his career after beating Adrian Mannarino 7-5 6-1 at the Astana Open.

This has been a tough season for the Australian, who had not managed to wins at the same Tour-level event since the Australian Open until this week.

But a string of impressive results against Fernando Verdasco, Tommy Paul and then Frances Tiafoe secured a final meeting with Mannarino.

The Frenchman's 2020 struggles have been even more stark, taking a 6-14 record to Kazakhstan, and he proved an accommodating opponent for Millman, failing to take his opportunities.

Five break points came and went for Mannarino in the first set before Millman broke at the first attempt to take the opener.

Mannarino then offered little resistance in the second, waiting until the final game to squander his sixth and last chance as Millman claimed a straight-sets win.

Andrey Rublev has the chance to win his fifth ATP Tour title of the season on Sunday after Kevin Anderson retired hurt in their Vienna Open semi-final clash.  

Rublev was leading 6-4 6-1 when Anderson pulled out with a leg injury, which he had earlier led to a medical timeout for treatment. 

The Russian, who has won 18 of his past 19 matches, will take on Lorenzo Sonego in Sunday's final, the Italian following up his stunning quarter-final victory over Novak Djokovic with a 6-3 6-4 win over Dan Evans.  

Rublev is on the brink of qualifying for the season-ending ATP Finals in London next month, but the 23-year-old insists he is not setting any expectations and simply wants to continue with the relaxed approach that has served him so well in 2020.  

"I don't know why it's going so well," he said. "I have such an amazing team and such amazing friends around me that always support me. That's probably why I'm playing so well. 

"I came here thinking that I have nothing to lose. I have already played a really great season, so I came here to enjoy it, do my best, fight for every point and now here I am in the final.

"I want to keep thinking the same way and we'll see what's going to happen tomorrow."

Sonego, meanwhile, admits he can scarcely believe he made the final after initially losing in the final round of qualifying against Aljaz Bedene, only to get into the main draw once Diego Schwartzman. 

He becomes the first lucky loser to reach the Vienna Open final since Andreas Haider-Maurer in 2010.  

"It's amazing," Sonego said. "I started this tournament [by losing] in the qualifiers. It's not easy after losing my [qualifying] match to win four matches and now I got to the final. 

"I don't have any expectations. I go with confidence and I [will] try to do my best tomorrow."

World number one Novak Djokovic is out of the Vienna Open after a shock 6-2 6-1 quarter-final defeat to unfancied Lorenzo Sonego.

Ranked 42 in the world, Sonego had failed to win a single set in his three previous meetings with players inside the top 10.

But the 25-year-old Italian produced a scintillating performance against the top seed as he became the first lucky loser to beat Djokovic.

"It's unbelievable. It's amazing," Sonego said in an interview on court after wrapping up the win in 68 minutes.

"For sure, it's the best victory of my life. Novak is the best in the world. I played so, so good."

Djokovic's surprise exit at the Wiener Stadthalle meant the Serbian missed the opportunity to guarantee top spot in the year-end ATP Rankings this week.

The 33-year-old is still poised, however, to tie Pete Sampras' record of six year-end number one finishes unless Rafael Nadal takes up an unlikely wildcard for next month's Sofia Open, with reports indicating the Spaniard has already rejected such an opportunity.

Grigor Dimitrov ended third seed Stefanos Tsitsipas' Vienna Open hopes with a battling last-16 win on Thursday.

Tsitsipas, who took Novak Djokovic to five sets in the French Open semi-finals this month, had come from behind to beat Jan-Lennard Struff in his opener in Austria but was this time on the wrong end of a fightback.

The Greek edged the first set after a tie-break but failed to convert either of his break points in a 6-7 (5-7) 6-4 6-3 reverse.

It was Dimitrov who prevailed after two hours and 14 minutes for his first top-10 win of the season, securing a quarter-final against Dan Evans.

"It's never easy to come out of a situation like that," Dimitrov said. "I was focused, but he went for it.

"In the tie-break a few close calls here and there went his way. [There was] not much else I could have done, I felt. But I kept on believing and kept on doing the right things.

"I stayed in the match, which I think was the most important thing. He's such a great competitor. You always have to be ready. I was just focusing on the most simple things of the game."

The other seeds found life a little easier on Thursday, with Dominic Thiem and Andrey Rublev each through to face one another.

Reigning champion Thiem brushed aside Cristian Garin in straight sets, while Rublev was granted a walkover as Jannik Sinner succumbed to a foot injury early in their meeting.

Daniil Medvedev also advanced but needed three sets after dropping the first to Vasek Pospisil.

Djokovic was not in action, meanwhile, but learned the identity of his Friday quarter-final opponent as Lorenzo Sonego reached the last eight.

Novak Djokovic will almost certainly finish the year at the top of the ATP world rankings for a joint-record sixth time after he claimed a hard-fought win over Borna Coric at the Vienna Open. 

Djokovic needed to win just two matches in Austria to guarantee he will end the year as world number one, unless Rafael Nadal takes up an unlikely wildcard for the Sofia Open. 

After defeating Filip Krajinovic in the first round, Djokovic took a vital step towards cementing his name in the record books with a 7-6 (13-11) 6-3 victory over Coric on Wednesday. 

Pete Sampras is the only previous player to have claimed the year-end number one spot on six occasions, doing so between 1993 and 1998. 

Djokovic is tied with fellow modern greats Rodger Federer and Nadal, who the Serbian lost to in the French Open earlier in October, and Jimmy Connors, but is now set to nose ahead of his rivals, having previously secured top spot in 2011, 2012, 2014, 2015 and 2018. 

His latest win did not come easy, though, with the 33-year-old made to work by world number 24 Coric. 

The pair traded blows in an epic opening set which lasted just under two hours – Djokovic eventually coming out on top in a thrilling tie-break after Coric dropped serve for a third time. 

A first break in set two handed Djokovic the advantage and he then held his nerve to take the eighth game with some wonderful shots in an exhilarating rally, making it 5-3. 

Djokovic's sublime volley close to the net set the tone in the next game and while Coric saved two match points, it was only a case of delaying the inevitable.

Earlier, Stefanos Tsitsipas opted to switch his shoe in the third set of his match with Jan-Lennard Struff, though the third seed ultimately came through the contest to tee up a tie with Grigor Dimitrov. 

With the third set tied at 1-1, Nitto ATP Finals champion Tsitsipas changed his footwear and subsequently broke serve, going on to record a 6-7 (7-3) 6-3 6-4 triumph. 

Daniil Medvedev, meanwhile, is enjoying the hospitality in Austria as he eased past Jason Jung 6-3 6-1 in his first-round match. 

"It's great. The hotel is good, the food is amazing, maybe the best of the year," said the world number six. 

"These small things make tennis players happy all the time. The most important is to play good on the tennis court, so the organisation is very good."

Alexander Zverev sealed his second ATP title in the space of a week as the German overcame Diego Schwartzman in the Cologne Championships final.

World number seven Zverev beat Felix Auger-Aliassime to claim the Cologne Indoors title on October 18 and continued his fine form in the city with a 6-2 6-1 triumph on Sunday.

Schwartzman had denied Auger-Aliassime the chance to avenge his previous defeat but was never a match for in-form Zverev, who hit nine aces – to his opponent's zero – and saved the only break point he faced.

After an even start, Zverev nosed himself ahead with a break of Schwartzman's serve in the fifth game of the opener, with another concession from the Argentine following.

Zverev swiftly wrapped things up with his first set point, though Schwartzman rallied to gain a break point in the opening game of the final set.

It was an opportunity the world number nine failed to grasp, however, and Zverev made him pay with some clinical shots, rounding off the victory – and his second title of 2020 – with a supreme forehand down the line.

Ugo Humbert captured his second ATP Tour title by defeating Alex de Minaur 6-1 7-6 (7-4) in the European Open final.

After saving four match points to book his place in the final, world number 38 Humbert charged to victory in an hour and 38 minutes against the eighth seed.

The Frenchman joined Jiri Vesely, Reilly Opelka and Novak Djokovic as the only players in 2020 to have won a title after staving off a match point in the tournament.

Humbert produced a spectacular forehand on the run before claiming his second break of the first set, which he sealed despite facing two break points.

De Minaur saved two break points at 4-4 in the second but paid the price for losing four straight points in the tie-break after taking a 3-1 lead, with Humbert sealing the win courtesy of a brilliant volley.

"It is one of my biggest wins," said Humbert. "I am super happy to win my second title this year against a really great player. I was aggressive like the previous matches and I am super happy to do it.

"Tennis is completely crazy sometimes. I don't know what happened today, it was a really nice level, a great match."

Alexander Zverev defeated Jannik Sinner in straight sets in Saturday's Cologne Championships semi-final to remain on course for a second ATP title in the space of a week.

The 23-year-old lost to Sinner at the last-16 stage of the French Open earlier this month but was too strong for the wildcard entrant in this latest match, prevailing 7-6 (7-3) 6-3.

Zverev, who carried a hip injury into the contest, lost serve in the fourth game but responded well and converted his first match point with a blistering serve.

He held throughout the second set and will now face Diego Schwartzman, who beat last week's beaten Cologne Indoors finalist Felix Auger-Aliassime in the other semi.

Second seed Schwartzman came out on top 6-4 5-7 6-4 in two hours and 31 minutes to reach his third final of 2020, converting four of five break points.

Ugo Humbert saved four match points against Dan Evans on the way to reaching the European Open final in Antwerp, meanwhile, battling to a 4-6 7-6 (9-7) 6-4 victory.

The opportunities for Evans all came the Briton's way in a second-set tie-break, with Humbert coming back from 6-3 behind and then 7-6 in the breaker to keep his hopes alive.

He found a way to level the match before edging the decider, with the 22-year-old French left-hander sealing his place in a second final of 2020 after winning in Auckland back in January.

It took him three hours and 14 minutes to complete the task, but at least Humbert had the evening off as Alex de Minaur and Grigor Dimitrov battled it out to join him in the final.

And it was eighth-seeded Australian De Minaur who claimed the victory in a tight match that lasted two hours and 48 minutes.

De Minaur held his nerve to triumph 7-6 (7-4) 6-7 (3-7) 6-4 to reach his first tour-level final in 12 months, losing to Roger Federer on the previous occasion at the Swiss Indoors Basel.

Diego Schwartzman took a big step towards qualifying for the ATP Finals with a "crazy" comeback win over Alejandro Davidovich Fokina in the Cologne Championships quarter-finals. 

The Argentinian was staring down the barrel of defeat when he lost the opening set and trailed 5-2 in the second, with Davidovich Fokina unable to convert a match point. 

After his opponent failed to capitalise, Schwartzman recovered to win 2-6 7-6 (7-3) 6-1 to set up a semi-final with either Felix Auger-Aliassime or Yoshihito Nishioka. 

Schwartzman is aiming to secure one of the final two spots for the ATP Finals and occupies the final qualifying berth. 

"Tennis sometimes is crazy," said Schwartzman after the match. "Maybe today I got lucky to be here answering questions.  

"But that is why I am here as well with this ranking, because I am always trying to find a way to win the matches. Today was not the exception to the rule." 

Home favourite and top seed Alexander Zverev came through in three sets, beating Adrian Mannarino 6-4 6-7 (5-7) 6-4. He meets Jannik Sinner, who recovered from losing eight straight games to defeat Gilles Simon 6-3 0-6 6-4, in the other last-four match. 

At the European Open, Dan Evans saved match point en route to ousting third seed Karen Khachanov 3-6 7-6 (9-7) 6-4 and will go up against Ugo Humbert in the semi-finals after the Frenchman beat Lloyd Harris in straight sets. 

Alex de Minaur hammered Marcos Giron 6-3 6-0 in under an hour and faces Grigor Dimitrov next, with the Bulgarian handed a walkover after Milos Raonic withdrew before the match due to an abdominal strain. 

Diego Schwartzman eased to a straight-sets win over home hope Oscar Otte but there was a shock in store for Denis Shapovalov at the Cologne Championships.

Second seed Schwartzman, ranked ninth in the world, needed just 81 minutes to seal a 6-3 6-2 victory, setting up a third-round meeting with Alejandro Davidovich Fokina.

It was a less happy outing for third seed Shapovalov in Germany, the Canadian succumbing to a 6-1 4-6 6-2 loss against Gilles Simon.

The result represented a measure of revenge for Simon after the Frenchman lost to world number 12 Shapovalov in the first round of the French Open.

"I am really happy with the way I played, with the focus I had over all of the match," Simon said in his on-court interview. 

"I am really happy to beat him, because it is a very, very good win. I had a tough match with him at Roland Garros. I lost it unfortunately, so I am happy that I am the winner this time."

Jannik Sinner awaits for Simon after he defeated Pierre-Hugues Herbert, while Yoshihito Nishioka also made it through.

At the European Open in Antwerp, top seed and home favourite David Goffin suffered a stunning 6-3 7-5 defeat to American qualifier Marcos Giron.

Giron's surprise victory put him in the last eight of a ATP Tour event for the first time and he saved 10 of 13 break points he faced for a maiden victory over a top-20 opponent.

Milos Raonic was not to be denied a place in the quarter-finals, though, and a 7-5 7-6 (7-4) defeat of Cameron Norrie means he will now meet Grigor Dimitrov.

Alexander Zverev started his quest to win back-to-back ATP tournaments in Cologne with a battling victory over John Millman.

Zverev was crowned Cologne Indoors champion last weekend and the US Open runner-up moved into the quarter-finals of the Cologne Championships on Wednesday.

The top seed beat Australian Millman 6-0 3-6 6-3, despite double-faulting 10 times, and has now won 11 of his last 12 matches on hard courts.

Zverev saved six of the seven break points Millman earned and won 79 per cent of points behind his first serve, setting up a last-eight meeting with eighth seed Adrian Mannarino.

Mannarino was a 6-3 6-3 winner against Miomir Kecmanovic, while Alejandro Davidovich Fokina advanced to the quarter-finals following a 7-6 (7-3) 6-3 victory over Steve Johnson.

Felix Auger-Aliassime, beaten by Zverev in the final on Sunday, rallied past qualifier Egor Gerasimov 4-6 7-6 (7-2) 7-6 (7-4).

Pablo Carreno Busta slumped to a surprise defeat at the European Open in Antwerp, Ugo Humbert beating the second seed 5-7 6-3 6-4.

Frenchman Humbert was joined in the quarter-finals by Grigor Dimitrov, Alex De Minaur and Dan Evans, while Milos Raonic and Taylor Fritz progressed to the round of 16.

Jannik Sinner raced past lucky loser James Duckworth in the first round of the Cologne Championships, where John Millman booked a meeting with top seed Alexander Zverev. 

French Open quarter-finalist Sinner took just 61 minutes to seal a 6-1 6-2 victory against Duckworth, who replaced Hubert Hurkacz after the Pole withdrew due to food poisoning. 

The 19-year-old Italian reached a career high 46 in the rankings following his exploits at Roland Garros and cruised past Duckworth after fending off two break points in a 12-minute game at 2-2 in the second set. 

Sinner will go up against qualifier Pierre-Hugues Herbert in round two after the Frenchman defeated Tennys Sandgren 6-3 3-6 6-3 at the ATP event on Tuesday. 

Zverev defeated Felix Auger-Aliassime in the final of last week's tournament in Cologne and will begin his bid for a second straight title against Millman after the Australian overcame Fernando Verdasco 6-4 6-2. 

At the European Open in Antwerp, Alex De Minaur came from a set down to defeat veteran Richard Gasquet 3-6 7-6 (7-5) 6-3. 

When serving for the set in the second set, Gasquet produced an unforced error following a reactive backhand from De Minaur. He then double faulted at 5-5 in the tie-break and the Australian eighth seed dished out the ultimate punishment. 

Federico Coria stepped in after Kei Nishikori withdrew due to a right shoulder injury and the Argentinian was comfortably beaten 6-2 6-3 by Pablo Andujar.
