The top two seeds were eliminated in the second round of the Pan Pacific Open in Tokyo as Paula Badosa and Caroline Garcia both crashed out on Wednesday.

Badosa was defeated in just 78 minutes by Zheng Qinwen, with the number one seed going down 6-3 6-2.

It was 19-year-old Zheng's first completed win against a top 10 opponent in her career, and she said afterwards: "Even though the score was like this, there were a lot of emotions for me in this match and I'm very proud of myself. It's not a surprise. I always knew I had the level, I just had to make it."

Second seed Garcia hit 27 aces in her match against Zhang Shuai, the most in a single WTA-level contest since Kristyna Pliskova against Monica Puig in Luxembourg 2019 (28), but it was not enough as she lost two tie-breaks to lose 4-6 7-6 (7-5) 7-6 (7-5).

Number three seed Garbine Muguruza had more success as she beat Greek opponent Despina Papamichail 6-4 6-2, while Claire Liu also eased to a win against Elise Mertens 6-4 6-1, and will play Zheng in the quarter-finals.

Eighth seed Elena Rybakina suffered a first-round exit as she lost to Liudmila Samsonova 6-2 6-4, who will play Xinyu next.

The seeds fared better over at the Korea Open, with Emma Raducanu sealing a first-round win against Moyuka Uchijima 6-2 6-4, while Magda Linette also eased past Arianne Hartono, 6-2 7-5, though fifth-seed Varvara Gracheva was knocked out by Anna Blinkova 6-4 7-6 (7-1).

In the second round, third seed Ekaterina Alexandrova is through after beating Han Na-lae 6-1 6-3, as is Lin Zhu of China following her straightforward 6-1 6-3 victory against India's Ankita Raina.

There were also wins for Tatjana Maria against Kimberly Birrell, and 17-year-old Andorran Victoria Jimenez Kasintseva against eighth seed Rebecca Marino.

Ahead of his retirement from tennis, Roger Federer has said he "totally overachieved" in the game.

The 20-time grand slam champion announced last week he will bring an end to a highly decorated career after the upcoming Laver Cup.

Speaking to BBC Breakfast, Federer admitted his disappointment in being forced to retire through injury, but reflected on one of the most impressive careers the sport has ever seen.

"The last three years have been tough to say the least," he said. "I knew I was on very thin ice for the last year ever since I played Wimbledon.

"I tried to come back but there was a limit to what I could do. And I stopped believing in it, to be honest."

After a scan earlier in the year that Federer said was "not what I was hoping for", he added: "Very quickly we realised this was it.

"Then the question becomes 'How do you announce and when do you announce?' This is when it becomes reality. It was OK but stressful."

The 41-year-old had been spending the last few weeks preparing his retirement statement, and said that part of the process almost felt like "rehab".

"It's been an emotional few weeks to go through those words to try to get them right, that they reflect how I'm feeling and thanking all the people who have helped along the way," he said.

"I always pushed my retirement thoughts away. I said, the more I think about it, the more I'm already halfway retired and this is not the way to go to work, you know, for me as a tennis player, so we'll deal with it when it comes. And it did. And I dealt with it.

"I think writing those words was, for me parts, partially also like rehab, like going myself through all those words, feeling them."

Federer has spent 750 weeks in the top 10 of the men's singles rankings, the highest tally for a male player since they were first published in 1973.

The Swiss maestro has also won more men's singles main draw matches in grand slam tournaments than any other player in the Open Era (369).

"I don't think anybody grows up and thinks they're gonna win this much," he added. "You know, you're happy with winning a Wimbledon title, which is already crazy, or becoming number one, being the best.

"But then you don't think how many weeks, this is only the media and the fans talking about breaking records.

"Before it was just, I hope to be on tour one day. Just to make it into the top 100 is a huge deal. Coming from a small country, we don't have a base of so many players.

"I totally overachieved in my mind. It's been an absolute dream that I've had for so long. And I know that, and that's why I'm totally happy to step away as well."

Federer also praised the "incredible storytelling" in the game, and reminisced about the period of dominance after his emergence was followed by Rafael Nadal, Novak Djokovic and Andy Murray through the 2000s.

"When I came up, we didn't expect it either," he said. "We were more on a bit of a downslope after [Pete] Sampras retired. What's gonna come next, right? Well, here I came, and then came Rafa. And then there was Novak, and then Andy, all together.

"All of a sudden, there was this beautiful mix, we're all winning for 10 plus years, all the same tournaments, almost nobody else could win anything else. It was like a lock on the big tournaments.

"So I think, also for the fans, it's been a joy to watch, and I'm sure some fans will be sad I'm leaving, of course, but then again, there will always be wonderful new people.

"I think our tour allows for incredible storytelling so that's why I know that the game is very safe, and I'm sure it will see incredible new superstars."

Taro Daniel has booked a matchup against top overall seed at the San Diego Open Daniel Evans after defeating Emilio Nava 6-4 6-3 in the opening round on Tuesday.

Daniel started beautifully, securing a break in the first game of the match, and his superior returning ability would carry him through the first set, winning 51 per cent (21-of-41) of his return points in the opening frame.

It was Daniel's serve which controlled the second set, winning 80 per cent (16-of-20) of his service points while allowing no break point opportunities for Nava, finishing the job in 94 minutes.

He will play world number 25 Evans next, who he has beaten in two of their past three meetings, although they have only gone head-to-head once since 2015 – in 2019, when Daniel won in straight sets.

Meanwhile, Mitchell Krueger ended a three-match losing streak against American compatriot Christopher Eubanks with a 6-4 6-4 triumph.

Eubanks had the power advantage, winning the ace count nine-to-four and the winner count 25-to-18, but he was also far sloppier, committing all four of the match's double faults as well as totalling 20 unforced errors to Kreuger's four.

In a clash between two veterans, 30-year-old Denis Kudla proved to be too much for 38-year-old Fernando Versaco, winning 6-3 6-3 to relegate the Spaniard to four losses from his past five matches.

In the final match of the night, Brandon Nakashima overcame Zachary Svajda 7-5 7-6 (7-5) after a gruelling 69-minute second set, contesting 96 points in the second frame after 66 in the first.

David Goffin fell to a first-round exit at the Moselle Open in Metz on Tuesday, as Nikoloz Basilashvili received a reprieve courtesy of Zizou Bergs' retirement.

Goffin, who won the event in 2014, fell to a 6-3 6-3 defeat to three-time champion Gilles Simon, who is set to retire at the end of the 2022 campaign.

Simon needed 93 minutes to wrap up his victory over the four-time grand slam quarter-finalist, teeing up a round-of-16 meeting with Italy's Lorenzo Sonego. 

"We've known each other for a very long time and I’m always happy to play against [Goffin] one more time before the end," Simon said after the win. 

"It was really perfect from the start until the end and that's how I won this one."

Elsewhere, Basilashvili was a set down in his meeting with Bergs when the Belgian qualifier was forced to retire through injury, allowing the fifth seed to progress to a meeting with Arthur Rinderknech.

Rinderknech downed Spain's Jaume Munar in three sets to reach the next round, while Emil Ruusuvuori comfortably saw off Jiri Lehecka 6-4 6-4.

Rafael Nadal has declared his career is "far from" over despite an injury-plagued 2022.

The 22-time grand slam champion has won both the Australian and French Opens this year despite suffering numerous injuries, while seeing other stars hang up their rackets.

Serena Williams announced her intention to retire ahead of the US Open, with Roger Federer following suit as he prepares for a farewell at this week's Laver Cup.

However, speaking after receiving the 'Camino Real Award' from King Felipe VI at the University of Alcala, the 36-year-old made it clear he does not intend to do likewise.

"It is also true that it has been a complicated year, not only because of injuries, which have followed me throughout my career, but also because of personal and family news, which in this case is very good news," he said.

"It is for this reason that, in a year full of joys and difficult moments, to receive recognition like today's is a great joy.

"I hope that this event does not imply that my career is over, far from it, or at least that is not the intention.

"The intention is to continue to carry the name of Spain around the world while I am still active and competing."

Nadal is set to compete alongside Federer at the Laver Cup in London, with Team Europe also featuring Casper Ruud, Stefanos Tsitsipas, Novak Djokovic and Andy Murray.

Team Europe have won all four previous editions of the Laver Cup, including a 14-1 thrashing of Team World in Boston last year.

Roger Federer looks set to play the final match of his tennis career on Friday after opting to only take part in doubles at the Laver Cup, and has described his great rival Rafael Nadal as his "dream" partner.

Federer is set to join the likes of Nadal, Novak Djokovic and Andy Murray – the other members of tennis' 'Big Four' – in representing Team Europe at the O2 Arena in London, but his fitness issues have led to doubts over the extent of his involvement.

On Sunday, fitness coach Pierre Paganini said Federer would make "a last-minute decision" regarding the nature of his participation in the Laver Cup.

Paganini added: "His aim is to play something, though whether it's singles or doubles we'll have to see," and Federer appears to have opted for the latter option.

On Tuesday, Federer told the Swiss press he would only be appearing in doubles at the event, though his partner is yet to be revealed.

"I'm happy and surprised at how good my shots are. But I won't be able to play singles, that was pretty clear beforehand," he told NZZ.

"That's why it was no longer an option to compete at the Swiss Indoors at the end of October. I guess I'll play doubles here on Friday night and that's it."

Nadal, one of just two men's players to have won more grand slam titles than the Swiss maestro (22, also Novak Djokovic with 21) appears the most obvious candidate, with Federer telling SRF: "Maybe I can play doubles with Rafa, that would be an absolute dream."

Asked whether he had any regrets at the end of his career, Federer added: "Of course, there are smaller things, but I can't think of any examples. I see it as an absolute dream career.

"I had a relaxed childhood. If I had been a bit more professional when I was younger, I might have been more successful. 

"But then I might have burned out earlier because it would have been too serious for me." 

The Swiss great, who has won 20 grand slam singles titles, announced last week that he was to retire from tennis after battling knee injuries.

When revealing the end of his career was imminent, Federer said: "I've worked hard to return to full competitive form. But I also know my body's capacities and limits, and its message to me lately has been clear".

Naomi Osaka began the defence of her Pan Pacific Open crown with a quick win after opponent Daria Saville was forced to retire in just the second game.

Four-time grand slam champion Osaka won the opening game, before Saville was unable to continue due to a scary-looking injury to her left knee.

The former world number one will now face a second round match with world number 16 Beatriz Haddad Maia, who eased to a straight sets victory over Yuki Naito.

Karolina Pliskova secured her place in the next round in Tokyo with a 6-2 6-1 demolition of Isabella Shinikova, while Zhang Shuai will face second seed Caroline Garcia on Wednesday after overcoming Mai Hontama in two sets.

In Seoul, Jelena Ostapenko's hopes of repeating her 2017 heroics at the Korea Open are still alive after the number one seed narrowly beat 19-year-old Jeong Bo-young.

The world number 19 looked to be cruising after the opening set, but the unheralded South Korean hit back in the second and took it to a tie-break in the third, before Ostapenko's class showed as she won the crucial tie-break 7-2.

Elsewhere, 2021's beaten finalist Kristina Mladenovic saw off wildcard Park So-hyun 6-4 4-6 6-3, while second seed Ekaterina Alexandrova overcame a worrying second set to beat Asia Muhammad 6-1 3-6 6-1.

Wimbledon semi-finalist Tatjana Maria is also safely through to the second round after a tight 7-6 (7-5) 7-6 (7-5) triumph over Eugenie Bouchard.

Seventh seed James Duckworth edged compatriot Alexei Popyrin in three sets, while eighth seed J.J. Wolf got past Stefan Kozlov in the San Diego Open first round on Monday.

Duckworth sent down 14 aces, winning 85 per cent on his first serve, and hit 53 winners as he got past Popyrin 7-5 4-6 6-1 in two hours and 20 minutes.

Popyrin could only manage 35 winners with 18 unforced errors. Duckworth will face one of the American qualifiers, Mitchell Krueger and Christopher Eubanks in the next round.

Wolf needed one hour and 52 minutes to topple countryman Kozlov 6-2 7-6 (8-6), converting three of his six break points, getting the edge by winning 50 per cent on Kozlov's second serve.

In the battle of the Argentines, Tomas Martin Etcheverry defeated Facundo Mena 7-6 (8-6) 6-3. Mena hit 28 winners but was undone by 23 unforced errors.

Frenchman Constant Lestienne fought back from a set down to win over American wild card Brandon Holt 5-7 7-6 (7-5) 6-3.

Four-time grand slam champion Naomi Osaka admitted she has not had "the best year" but is still "pretty happy with where I am now."

Osaka – a former world number one – has slipped to 48th in the latest WTA rankings, and has not won a match at a grand slam since she beat Madison Brengle in the second round at the Australian Open in January.

The Japanese-born star was eliminated in the first round at the French Open and US Open this year, and did not compete at Wimbledon due to an Achilles injury.

Having taken some time away from the game last year to focus on her mental health, Osaka has struggled to get back to her previous high levels.

However, speaking ahead of the Pan Pacific Open in Tokyo, she seemed calm about the situation, as she suggested she is improving both on and off the court.

"It was kind of hard at first, just because I feel like I should be somewhere where I'm obviously currently not," the 24-year-old said.

"I think for me, it's more about being at peace with myself. I know that I'm here for a reason."

Osaka has seven career singles titles to her name, including four majors – she has won twice at Flushing Meadows and twice at the Australian Open.

"This year has not been the best year for me, but I've learned a lot about myself," she added.

"Life is ups and downs, and this year was more down than up, but overall I'm pretty happy with where I am now."

She is preparing to defend her title at the Pan Pacific Open, which has not been held in three years due to the coronavirus pandemic, starting with a match against Daria Saville on Tuesday.

"It feels really weird to hear that I'm the defending champion because it was the last time I played in 2019," she said.

"I would love to win it again, but I think just taking it one match at a time... and also just playing in front of a crowd in Tokyo again, because the Olympics was crowdless, so it will just be nice to see people."

Sebastian Korda and Lorenzo Sonego progressed to the second round of the Moselle Open on Monday, while Stanislas Wawrinka came through qualifying.

Korda was playing his first indoor match since the decider of the Next Gen ATP Finals last November, and Hugo Gaston represented a tough opening test.

But the American prevailed in straight sets against the home favourite, winning 6-3 7-6 (7-2) after defending set points in the second set and blowing his opponent away in the subsequent tie-break.

Another tricky opponent awaits, with number three seed Lorenzo Musetti up next in the second round.

Musetti's Italian compatriot Sonego also succeeded in Monday's only other main-draw match, beating sixth seed Aslan Karatsev 7-5 6-3 to set up a last-16 clash with either Gilles Simon or David Goffin.

In the qualifying section, three-time grand slam champion Wawrinka beat Zsombor Piros 6-7 (4-7) 6-2 6-0 to reach the first round, where Joao Sousa awaits.

The winner of that match will face top seed Daniil Medvedev in the last 16.

Alison Riske-Amritraj suffered another early exit as the Pan Pacific Open began in Tokyo on Monday.

Riske-Amritraj reached the last 16 at the US Open earlier this month but has struggled in Asia since then.

She was the top seed at the Chennai Open last week, only to lose in straight sets in the first round to Anastasia Gasanova.

And the American fell at the first hurdle again in Japan.

Riske-Amritraj was drawn against compatriot Claire Liu, who was coming off back-to-back defeats to Anastasia Potapova and without a win since qualifying for the Canadian Open last month.

But Liu brushed aside the seventh seed 6-2 6-3 to set up a meeting with Elise Mertens in the second round.

Mertens eased through with a 6-0 6-3 win over Wang Qiang, while Petra Martic was similarly comfortable in a 6-1 6-1 defeat of Rina Saigo.

Saigo was one of two home hopefuls to depart on Monday as Qinwen Zheng won 19 points in a row en route to beating Misaki Doi 6-2 6-4.

At the Korean Open, Zhu Lin was the only seed in action and got the better of Jang Su-jeong in straight sets.

Katerina Siniakova ended her five-year wait for a WTA singles title after coming from behind to defeat Elena Rybakina and claim the Slovenia Open crown.

The Czech secured the third singles triumph of her career – and first since prevailing at Bastad in 2017 – as she recovered from losing the opening set to deny Wimbledon champion Rybakina 6-7 (4-7) 7-6 (7-5) 6-4.

Siniakova – also the doubles world number one – continued her rich vein of form, having captured her third grand slam of 2022 alongside Barbara Krejcikova at the US Open last week.

The world number 82 had come through two matches on Saturday to reach the championship match in Portoroz, and was slow out of the blocks as she fell 5-0 behind in the opening set. Although Siniakova fought back to force the tie-break, Rybakina held her nerve by winning four of the last five points to draw first blood.

The Wimbledon champion, who hit 43 winners, appeared to be closing in on victory in her third final of the year as she broke for 4-3 in the second set. However, Siniakova broke back immediately before eventually forcing a decider.

Both players exchanged breaks early on in the third, but Rybakina's increasing unforced error tally (66) eventually culminated in her opponent claiming another crucial one for 5-4, before serving it out to end the drought.

Over at the Chennai Open, teenager Linda Fruhvirtova also enjoyed a comeback victory as she denied Magda Linette 4-6 6-3 6-4 to land her maiden WTA title.

Aged 17 years and 141 days, Fruhvirtova became the youngest winner on the WTA Tour this season, and is set to climb into the world's top 100 for the first time.

In a tight opening set, Linette broke for 5-4 before holding to love to strike first. A solitary break also proved crucial in the second set; the Czech profiting on this occasion to ensure the final went to a decider.

Linette, who won just two out of nine break points, established early control as she surged into a 4-1 lead, but Fruhvirtova came roaring back as she reeled off five straight games to seal a fitting end to her breakthrough week.

Casper Ruud expects to be "a bit nervous" when he features alongside childhood heroes Novak Djokovic, Rafael Nadal, Andy Murray and the retiring Roger Federer at the Laver Cup.

Ruud is the world number two heading into the tournament, which sees Team Europe take on Team World in London, after his efforts at the US Open.

The Norwegian fell just short against Spanish teenage superstar Carlos Alcaraz in the final at Flushing Meadows.

Ruud featured at last year's Laver Cup, held in Boston, and this year is due to join up with the 'Big Four' of Djokovic, Nadal, Murray and Federer, who has announced his impending retirement at the age of 41. The quartet have won 66 grand slam titles between them.

While there are some doubts over whether Federer will be fit enough to play in his farewell tournament, with the action starting on Friday, Ruud is "honoured" to have the opportunity to play alongside his idols.

"It's going to be so special this year, having the biggest four tennis players in my childhood," Ruud said in an interview on the Laver Cup's official website.

"It's going to be an honour. [I'm] probably going to be a bit nervous when I'm out there playing in front of them, but I'll do my best and I'm very happy to be able to represent Europe in front of a crowd full of cheerful fans, and a European bench of legends."

Ruud has played six matches against the illustrious quartet who will now be team-mates, winning only once – against Murray in San Diego last year.

The 23-year-old has lost three times to Djokovic and once to Nadal – in the final of the French Open this season – while his sole meeting with Federer, back in 2019 at Roland Garros, went the way of the 20-time major champion.

Federer helped to create the Laver Cup but did not play in the 2021 edition due to injury. He was, however, present to support Team Europe from the stands in Boston.

"I was playing the first match of the whole [2021] Laver Cup against [Reilly] Opelka," Ruud said. "It was the first time they showed Roger on the big screen in TD Garden in Boston, and the whole crowd erupted like I never heard before.

"I can only imagine what it will be like when he's on the team and when he will enter the court."

Federer announced the decision to bring the curtain down on his 24-year playing career on Thursday, having not competed since making the quarter-finals at Wimbledon last year.

Roger Federer will make a "last-moment decision" on his participation in next week's Laver Cup, according to fitness coach Pierre Paganini.

The 20-time grand slam champion announced on Thursday he will retire from top-level tennis after the tournament at London's O2 Arena.

However, Federer has not competed since Wimbledon 2021, after which he underwent a third knee operation.

And Paganini has cast doubt over whether the Swiss will be able to link up with the likes of Novak Djokovic, Rafal Nadal and Andy Murray in what is supposed to be his farewell event.

"This will probably be a last-moment decision," Paganini told Bilk. "He's practised at a level in order to determine exactly if playing is a good idea or not."

Federer is bringing down the curtain on a remarkable career that saw him win 103 ATP Tour-level titles – only Jimmy Connors (109) boasts more in the Open Era.

Among an array of other notable achievements, the 41-year-old spent a record 750 weeks in the top 10 of the men's singles rankings.

But Paganini says it "became clear a return to the Tour would be impossible" around July as injury problems took their toll on the all-time great.

In a more positive update, fellow coach Severin Luthi indicated Federer is on course to be fit to play at least some part in the Laver Cup.

"His aim is to play something, though whether it's singles or doubles we'll have to see," Luthi told Blick. "His aim is still to play at the Laver Cup – definitely.

"We train for three hours in the morning, then another two hours in the afternoon. He trained last week and is training again this week."

Wimbledon champion Elena Rybakina cruised to a straight sets victory over world number 65 Ana Bogdan to secure her place in Sunday's Slovenia Open final.

The Kazakhstan representative broke Bogdan five times while saving all eight break points to seal a 6-1 6-1 triumph and reach a first final since her SW19 victory over Ons Jabeur in July.

In the final, Rybakina will face Katerina Siniakova after she overcame Anna-Lena Friedsam.

Siniakova stormed to the first set, but the second was a much closer affair and the world number 82 watched five match points come and go before she finally clinched a 6-1 7-5 success.

At the Chennai Open, Magda Linette will play Linda Fruhvirtova in Sunday's decider after coming through semi-final encounters in differing fashion.

Third seed Linette raced out to a 3-0 lead in the first set over Katie Swan before the Brit called a medical timeout after just 16 minutes of play, eventually retiring with illness.

Fruhvirtova's semi-final was a much more gruelling affair, as the 17-year-old came from a set down to overcome Nadia Podoroska 5-7 6-2 6-4 and reach her first WTA final.
