Casper Ruud saw off a fightback from Nicolas Jarry to book his spot in the quarter-finals of the Korea Open, as well as this year's ATP Finals.

The top seed was given a second set scare by the Chilean but wrestled back control to emerge as the victor in a 6-2 3-6 6-3 encounter.

The two-time grand slam finalist, having been runner-up at Wimbledon and the US Open this year, will face Yoshihito Nishioka after he saw off Japanese compatriot Taro Daniel in a 6-2 6-4 win.

His victory also ensured his place at the ATP Tour's end-of-year finale in Turin, alongside Spanish duo Rafael Nadal and Carlos Alcaraz.

Cameron Norrie remains on course to set up a potential final in Korea with Ruud after brushing aside Kaichi Uchida with a comfortable 6-2 6-2 victory.

The Briton will face eighth seed Jenson Brooksby after he turned over home favourite Kwon Soon-woo in a 6-3 6-4 result in Seoul.

Brooksby's fellow Americans Mackenzie McDonald and Aleksandar Kovacevic also came through their last-16 encounters to set up a quarter-final clash against each other.

Marin Cilic had to come from behind to defeat Dominic Thiem as he sealed a spot in the quarter-finals of the Tel Aviv Open.

Cilic, who was also celebrating his 34th birthday, was given a thorough test initially by the wild card, but Thiem ultimately faded away.

After losing the first set, second seed Cilic eventually won 6-7 (6-8) 6-2 6-4 as he succeeded in putting the Austrian's serve under intense pressure, setting up a quarter-final with either fifth seed Botic van de Zandschulp or Liam Broady.

Reacting to the victory, Cilic said: "I think it was a fantastic match. I think it was an amazing, amazing level.

"We don't get so many chances to play [a] second-round [match] in front of this big [of a] crowd, so thank you so much. It was a fantastic birthday."

Maxime Cressy, seeded fourth, was far more comfortable as he defeated fellow American Sebastian Korda 6-4 6-4 thanks to a break of serve in either set.

The only other seed in action was seventh favourite Adrian Mannarino. The Frenchman came unstuck against his countryman Constant Lestienne, who won 7-6 (7-2) 6-4.

At the Sofia Open, two high seeds were surprisingly dumped out on Wednesday.

Home favourite Grigor Dimitrov, seeded third, was beaten in straight sets by Ilya Ivashka, who showed commendable focus to see out a 6-3 7-6 (7-3) win despite the crowd's support of his opponent.

Number six seed Nikoloz Basilashvili was the other big name to suffer a shock defeat, with 38-year-old Fernando Verdasco beating him 7-6 (7-1) 7-5 as the seven-time ATP Tour title winner rolled back the years.

Lorenzo Musetti bucked the trend, however. Seeded fourth, the Italian was made to sweat by Bulgaria's Alexander Lazarov as the first two sets went to tie-breaks, but the Italian had too much in the end as he won 6-7 (5-7) 7-6 (10-8) 6-2.

Earlier in the day, Musetti's compatriot Lorenzo Sonego comfortably dealt with Bernabe Zapata Miralles 6-3 6-4.

Novak Djokovic wants to replicate Roger Federer's emotional farewell by having all his tennis rivals present when he brings down the curtain on his own career.

Federer played his final top-level tennis match in last week's Laver Cup when partnering long-time rival and friend Rafael Nadal in doubles competition

Djokovic and Andy Murray, two of Federer's other great adversaries, were also part of the 41-year-old's side at London's O2 Arena.

Despite boasting an all-star cast of talent, Team Europe fell to a first ever defeat against Team World, yet it was Federer's teary send-off that made the headlines.

And Djokovic, who has no current plans to retire, would like to share a similar moment at the end of his playing days.

"It was just a very touching, very emotional moment," Djokovic told reporters ahead of his second-round match against Pablo Andujar at the Tel Aviv Open.

"Seeing his kids and his family, it got me emotional as well. I also must say I was thinking about how it would look for me when I say goodbye to tennis.

"There is definitely one thing that I will wish to have, other than, of course, my family and the close people in my life, I would love to have my biggest rivals and competitors there. 

"Because it added something more special; it added more importance to that moment."

Federer retires as a 20-time grand slam winner – one fewer major title than Djokovic, who is himself one behind men's record holder Nadal.

With Federer now out of the picture, Djokovic says Nadal remains his biggest rival on the court.

"We played the most matches against each other of any other rivalry in the history of tennis," he said. "The rivalry is very special and keeps going. 

"Hopefully, we'll get a chance to play against each other more times. Because it's exciting for us and also for tennis fans and sport fans around the world."

Denis Shapovalov claimed a spot in the quarter-finals of the Korea Open by seeing off the challenge of Spain's Jaume Munar on Wednesday.

The 2021 Wimbledon semi-finalist needed 109 minutes to claim a 7-5 6-4 win over Munar, assuming control by breaking in the seventh game of the opener before doing likewise early in the second set.

Canadian Shapovalov – who is seeded fourth for the event – had not featured since a dramatic loss to Andrey Rublev at the US Open earlier this month, but produced a consistent display in Seoul, not committing a single double fault during the match.

His reward for the victory is a last-eight tie with Radu Albot, who held his nerve in two tie-breaks to record a 7-6 (7-3) 7-6 (7-3) win over Steve Johnson.

In Wednesday's other match, Japan's Taro Daniel beat Ecuador's Emilio Gomez in straight sets in the duo's round-of-32 tie. 

Top seed Casper Ruud begins his campaign against Nicolas Jarry on Thursday.

Holger Rune saw off a spirited challenge from Tim van Rijthoven to progress to the second round of the Sofia Open on Tuesday, while a pair of seeds suffered surprise exits at the Tel Aviv Open.

Rune – the fifth seed for the tournament in Bulgaria – required two tie-breaks to clinch victory in his first meeting with Van Rijthoven on the ATP Tour, eventually claiming a 7-6 (7-2) 7-6 (8-6) win.

After the match, Rune expressed his relief at avoiding a third set, saying: "I didn't want to go to three sets. If it [had happened], I was going to fight for sure and try to take it in three, but I'm very happy to finish in two."

Meanwhile, eighth seed Oscar Otte beat Dragos Nicolae Madaras 6-3 6-2, and Portugal's Nuno Borges overcame Mirza Basic in three sets to tee up a meeting with defending champion and top seed Jannik Sinner.

In Tel Aviv, seeds Aslan Karatsev and Tallon Griekspoor fell at the first hurdle with three-set reverses to Tomas Martin Etcheverry and Vasek Pospisil, respectively. 

Etcheverry rallied after Karatsev took a second-set tie-break in comprehensive fashion to post a 6-2 6-7 (0-7) 6-4 win, while lucky loser Pospisil stunned Griekspoor for a 4-6 7-6 (7-3) 7-5 triumph.

Fifth seed Botic van de Zandschulp fared better, however, dispatching Joao Sousa 6-2 6-3 after producing a top-class display of serving.

The Dutchman will meet Britain's Liam Broady in the next round after he recorded a straight-sets win over Hamad Medjedovic.

Yoshihito Nishioka knocked fifth seed Dan Evans out of the Korea Open with a straight-sets victory on Tuesday.

Nishioka moved into the second round in Seoul with a 6-2 7-6 (7-3) defeat of the Briton.

The world number 56 from Japan will face Taro Daniel or Emilio Gomez in round two after winning 70 per cent of points on his first serve and breaking Evans four times.

Jenson Brooksby was forced to go the distance, but delivered a final-set bagel as the eighth seed saw off Wu Tung-lin 7-6 (7-5) 3-6 6-0.

Qualifier Nicolas Jarry will take on top seed Casper Ruud after defeating Ryan Peniston 6-3 7-6 (10-8), while American duo Mackenzie McDonald and Steve Johnson also advanced.

Tseng Chun-hsin progressed with Chris O'Connell retired with an injury after losing the first set before Kwon Soon-woo beat Yunseong Chung in an all-South Korean contest.

Dominic Thiem fought back from a set down to reach the second round of the Tel Aviv Open with victory over Laslo Djere.

The former US Open champion needed two hours and 40 minutes to produce the turnaround, his 5-7 7-6 (7-3) 6-4 win setting up a meeting with another former winner at Flushing Meadows, Marin Cilic.

"I didn't get off to a great start. I got the break in the second set, and then I was a bit lucky I could turn the match around," Thiem said on court after the match.

"The third set was a real grind. I am very grateful to everyone who came tonight. It is really nice to play in Israel."

Roman Safiullin beat Hugo Grenier in the day's other match.

At the Sofia Open, Ilya Ivashka, fresh off a run to the US Open last-16, defeated Mikael Ymer 7-6 (10-8) 4-6 7-5.

There were also wins for Kamil Majchrzak and Alexandar Lazarov.

Aleksandar Kovacevic marked his ATP Tour main-draw debut by knocking seventh seed Miomir Kecmanovic out of the Korea Open on Monday.

American Kovacevic was only playing in the first round as a lucky loser in Seoul after he was beaten in the final round of qualifying, but he grasped his chance by winning 6-4 6-4.

The 24-year-old served 14 aces and broke the world number 32 three times to set up a second-round meeting with Christopher O'Connell or Tseng Chun-hsin.

Radu Albot got the better of Hiroki Moriya in his first appearance in Seoul, while Jaume Munar progressed when Yosuke Watanuki retired early in their match due to an ankle injury.

Kaichi Uchida came out on top in the final match of the day, consigning Hong Seong-chan to a 6-4 6-2 defeat.

In an all-American final at the San Diego Open, Brandon Nakashima defeated Marcos Giron 6-4 6-4 to capture the first ATP Tour title of his career.

Nakashima, 21, was playing in the third final since arriving on the ATP Tour, having lost the deciders at both the Atlanta Open and the Los Cabos Open as a teenager back in 2021.

Against Giron, the first set lasted just 35 minutes as San Diego native Nakashima converted the only break point opportunity of the frame, while winning 80 per cent (20-of-25) of his service points.

In a spectacularly efficient display, Nakashima hit 15 winners and only one unforced error, while adding six aces with no double faults.

He cooled off slightly in the second set, but it was still more than good enough, posting another 15 winners with five unforced errors and grabbing a break of serve in the opening game.

Giron would finally nab his first break of the contest in a game where he converted on his fourth opportunity, but Nakashima immediately answered to jump ahead 4-2 and serve it out cleanly.

With the win, Nakashima will rise into the top 50 of the world rankings for the first time when it is next updated.

Roger Federer said he felt the pain of Team Europe's first Laver Cup defeat as the World team crashed the Swiss great's farewell party in breathtaking style.

The final event of Federer's playing career veered off the script as he and Rafael Nadal lost in doubles on Friday, before the team collectively succumbed to a 13-8 defeat in London.

Stunning singles wins for Felix Auger-Aliassime and Frances Tiafoe on Sunday, against Novak Djokovic and Stefanos Tsitsipas respectively, followed a doubles thriller that saw Auger-Aliassime and Jack Sock topple Andy Murray and Matteo Berrettini.

After Team Europe won the first four editions of the Laver Cup, this time they had to swallow the bitter pill of defeat, with Federer sorry to sign off on a losing note.

"Of course I'm disappointed," he said. "I was on the team. I almost lost my voice. My hands hurt from clapping.

"So, yes, I am disappointed. We wish the result would be different. I told Andy [Murray] in the locker room, I don't like losing. It's not fun. It just leaves not the best taste, you know. I think once you have been there and taste success, it's just not the same."

He said his goodbye tournament had been a mix of highs and lows.

"This weekend has been all over the place for me," said the 41-year-old Swiss. "I enjoyed it, but it's unfortunate that we couldn't get the win tonight."

Federer denied he has his eyes set on becoming the next Team Europe captain. Incumbent skipper Bjorn Borg and Team World counterpart John McEnroe have indicated next year's match could be the last that they helm, which would create an appealing vacancy.

"No plans there. Bjorn's doing a great job," said Federer. "Who knows, maybe one day, but we don't have any plans so far."

Next year's match takes place in Vancouver, and Federer will certainly have a role of some sort to play, given he is a co-founder of the event.

"I went through all different types of Laver Cups so far: the first one, the winning teams, now this time on the losing team," Federer said. "There was also one where I was hurt last year but seeing it more from the stands and from the fans' perspective, and now deep on the inside with retirement.

"I have enjoyed the Laver Cup in many different ways, and next year again will be totally different. I'm looking forward to it, and I'm sure Vancouver is going to be fantastic."

Asked what he would miss about tennis, Federer said: "Not the losing press conferences, I tell you that. They are the worst."

Felix Auger-Aliassime and Frances Tiafoe played starring roles as Team World won three matches on the spin on Sunday to claim a first Laver Cup triumph over Team Europe.

Team World went into the final day of action at the O2 Arena in London sitting four points behind their opponents, but they produced a stirring fightback to claim the trophy at the fifth time of asking.

Central to their success was Canadian Auger-Aliassime, who beat Novak Djokovic in singles after successfully teaming up with Jack Sock in the doubles.

Holding an 8-4 lead from Saturday, many expected Team Europe to breeze it from there, but John McEnroe's World team had other ideas and earned a 13-8 victory. 

Up first in the doubles were Auger-Aliassime and Sock, who lost the first set to Team Europe's Andy Murray and Matteo Berrettini.

However, the World duo roared back to deliver three points for their team by claiming a 2-6 6-3 10-8 victory.

Djokovic won two matches for Team Europe on Saturday, yet he was powerless to stop Auger-Aliassime in their singles clash. The 22-year-old Canadian landed a 6-3 7-6 (7-3) over the Wimbledon champion.

That moved Team World 10-8 ahead in the overall contest, setting the stage for a decisive clash between Stefanos Tsitsipas and Frances Tiafoe, with a further three points at stake.

Greek Tsitsipas won the first set, but 24-year-old American Tiafoe stormed back to win an epic tie-break in the second on his way to a 1-6 7-6 (13-11) 10-8 success.

Lorenzo Sonego fended off the challenge of Alexander Bublik to win Sunday's Moselle Open final and earn a return to the top 50 in the world rankings.

In Metz, France, unseeded Italian Sonego swept to a 7-6 (7-3) 6-2 victory in the trophy match, collecting the third ATP title of his career.

He enjoyed a stellar week at the ATP 250 event, following up wins over Gilles Simon and Sebastian Korda with a semi-final victory against second seed Hubert Hurkacz, not dropping a set across his four matches.

Sonego, who reached a career-high ranking of 21st in February, had drifted to 65th in the months since, but the ATP said he would climb back into the top 50 as a result of his title run. The ATP's live rankings on Sunday showed him making a leap of 20 places to number 45.

Bublik, the seventh seed, had reached the final after Stan Wawrinka withdrew from their semi-final due to injury. He kept pace with Sonego on Sunday in a tight first set where serves dominated and neither man could force a break, with success for the Italian in the tie-break breaking the resistance of his Kazakh opponent.

The second set proved to be one-sided as Sonego added the title to his previous triumphs on tour, also extending his winning head-to-head record against Bublik to 4-0.

This indoor hardcourt success followed previous wins on grass in Antalya in 2019 and on clay in Cagliari last year.

Sonego said in an on-court interview: "This is a really emotional moment for me. I'm really happy because I played my best tennis this week. It's been a tough year and I want to enjoy this moment."

Local hope Brandon Nakashima will take on Marcos Giron in the San Diego Open final after the latter shocked top seed Daniel Evans in Saturday's semi-finals.

World number 58 Giron upset Evans 6-3 7-5 in one hour and 46 minutes, qualifying for his maiden ATP Tour final.

San Diego native Nakashima progressed into the decider after getting past Australian Christopher O'Connell 6-4 7-6 (7-3).

Nakashima's triumph means he is into his first tour-level final of the season and it has come in familiar territory.

The fifth seed needed one hour and 50 minutes to beat O'Connell, who had the edge in the key statistics, including 8-7 aces, 34-31 winners and 13-16 unforced errors.

But Nakashima came up big when it mattered, managing the only break of the match in the first set, before triumphing in a tiebreak.

Giron produced the surprise result against world number 25 Evans, who was chasing his first-ever ATP Tour title.

The American sent down 11 aces, while he also hit 40-25 winners. Evans was unable to convert any of the three break points he generated throughout the match.

Stan Wawrinka abandoned his first ATP semi-final for over two years as the veteran Swiss bowed out of the Moselle Open on Saturday.

The 37-year-old was taking on Kazakhstan's Alexander Bublik and trailed 2-1 in the opening set when he decided he would be unable to complete the match.

Bublik had broken serve and led 40-30 in the fourth game when Wawrinka approached the net and told the umpire he had to stop.

Wawrinka has been battling a thigh injury that appeared to be the cause of his withdrawal, meaning the three-time grand slam champion, now ranked a lowly 284th, could not push on with his quest for a first ATP Tour title in five years. His most recent semi-final appearance, prior to this run in Metz, had come in Doha at the start of 2020.

Italy's Lorenzo Sonego awaits Bublik in Sunday's final after he sank the hopes of Polish second seed Hubert Hurkacz in the first semi-final.

Unseeded Sonego took the win 7-6 (7-5) 6-4 and will be chasing a third ATP title, after previous triumphs in Antalya in 2019 and Cagliari last year.

Bublik, the seventh seed this week, has just one previous singles title, earning that success in February of this year in Montpellier.

Roger Federer "made the whole world dream" through his tennis, French football great Zinedine Zidane said on Saturday.

The Swiss superstar contested his final match on Friday night in London, as he bowed out at the age of 41, accepting knee trouble in recent years would not allow him to carry on.

Zidane's last match as a player famously ended in a headbutt, a red card and crushing disappointment in the 2006 World Cup final, as France lost out to Italy on penalties in Berlin.

That was a far cry from the celebratory scenes at the O2 where 20-time grand slam winner Federer exited in a hail of adulation and high emotion, as the man from Basle broke down in a flood of tears on court.

The poignancy came after Federer lost alongside Rafael Nadal in a Laver Cup doubles clash with Jack Sock and Frances Tiafoe, a low-stakes occasion compared to Zidane's swan song.

Both Zidane and Federer played their sport with maverick and artistic tendencies that set them apart from many of their peers, while also winning a stack of trophies.

Zidane had two spells as Real Madrid boss after hanging up his boots following a playing spell at the Santiago Bernabeu, and he hopes there are great opportunities awaiting Federer too.

"Today you are stepping into another world. I wish you a second part of life as rich as the first," Zidane wrote on Instagram.

"Thank you Roger, you made the whole world dream! And you remained profoundly the same. Thank you Roger, the great class."
