Novak Djokovic is feeling "physically fresh and mentally motivated" after maintaining his positive form with victory over Botic Van De Zandschulp in round two of the Astana Open.

The Serbian brushed aside Cristian Garin in his opener and did likewise in Thursday's match with Van De Zandschulp, prevailing in just 71 minutes in the Kazakh capital.

Djokovic has now won six matches in a row and is seeking back-to-back titles after triumphing at the Tel Aviv Open last week – his 89th ATP singles crown.

He reeled off five games in a row in the second set to advance 6-3 6-1, with that his 30th tour-level victory of the year.

And as Djokovic nears the end of a rather mixed season, the 21-time grand slam winner is in the mood to add further titles to his collection.

"My season is different from any other so don't look at my season in comparison to others," he said in his post-match interview.

"I haven't played for over three months before Israel so I definitely am physically and mentally motivated to do well."

Awaiting Djokovic in the quarter-final is Karen Khachanov, who eliminated Marin Cilic with a 2-6 6-3 6-3 comeback victory.

World number four Daniil Medvedev also advanced thanks to a 6-3 6-2 win over Emil Ruusuvuori, while Hubert Hurkacz beat Alexander Bublik 6-4 6-4.

At the Japan Open, third seed Taylor Fritz defeated Hiroki Moriya in three sets and will now face fifth seed Nick Kyrgios, who recovered to beat Kamil Majchrzak 3-6 6-2 6-2.

Denis Shapovalov, looking to build on his run to the Seoul Open final, got the better of home hope Rio Noguchi with a 6-3 6-1 win to advance to the quarter-finals.

Emma Raducanu has withdrawn from the Transylvania Open with a wrist injury, compounding a miserable 2022 for the British number one.

The teenager became an overnight star on the WTA Tour last year when she won the US Open women's singles title in her first appearance at Flushing Meadows.

However, her attempts to follow up that success have been hamstrung by a succession of niggles, with Raducanu currently down at 67th in the world rankings.

Her withdrawal from next week's event in Romania – the country from which her father hails – is just the latest injury problem, with Raducanu having been forced to quit during the semi-finals of last month's Korea Open with a glute problem.

This followed a first-round retirement at the Nottingham Open before Wimbledon, though Raducanu ultimately recovered to reach the second round of the grass-court major.

A first-round exit at the Ostrava Open this week, followed by the latest setback, means Raducanu's season appears effectively over, with the 19-year-old likely to set her focus on regaining full fitness ahead of 2023.

Iga Swiatek is through to the quarter-finals of the Ostrava Open after Ajla Tomljanovic retired hurt in their second-round match on Wednesday.

The world number one had won the first set 7-5, but her Australian opponent was forced to concede at 2-2 in the second.

Swiatek is now the female player with the most wins in a single year (58) in the last five seasons. Former world number one Ash Barty recorded 57 victories in 2019.

The second seed in Ostrava is out after Paula Badosa was beaten 7-6 (7-4) 6-4 by Petra Kvitova in front of a delighted Czech crowd, while Elena Rybakina is also through to the last eight after coming from behind to win against Aliaksandra Sasnovich 6-7 (5-7) 6-4 7-5.

Wednesday's two other matches saw more success for Czech participants as Karolina Muchova beat seventh seed Beatriz Haddad Maia 6-4 6-4, while Barbora Krejcikova defeated Shelby Rogers 6-2 6-2.

There was less Czech joy at the Jasmin Open in Tunisia, where Katerina Siniakova was beaten 7-5 6-2 by Claire Liu.

Elsewhere, number three seed Alize Cornet eased past Harriet Dart 6-3 6-4, Elise Mertens came from behind to beat Despina Papamichail and Diane Parry went through against French compatriot Lucrezia Stefanini after the latter retired hurt in the second set.

Novak Djokovic breezed past Cristian Garin in the Astana Open, taking just 62 minutes to secure a 6-1 6-1 victory in his opening match of the ATP 500 event.

Having won his 89th tour-level title on Sunday in Tel Aviv without dropping a single set, fourth-seed Djokovic wasted no time in securing a win to set up a second-round clash against Botic van de Zandschulp.

Also in Kazakhstan, third seed Stefanos Tsitsipas made hard work of his second-round tie against Luca Nardi, requiring two tie breaks in a two-hour showdown in a 7-6 (7-2) 7-6 (7-3) victory to secure a spot in the last eight.

Andrey Rublev, Roberto Bautista Agut and Adrian Mannarino also sealed their places in the quarter-finals at the Astana Open on Wednesday, while Marin Cilic and Emil Ruusuvuori won their first-round matches.

Meanwhile, Taylor Fritz defeated James Duckworth 6-2 6-7 6-1 in the Japan Open, where there was also a victory for Denis Shapovalov against Steve Johnson.

In the doubles, top seeds Nick Kyrgios and Thanasi Kokkinakis overcame home duo Yoshihito Nishioka and Kaichi Uchida, with second seeds Matthew Ebden and Max Purcell also progressing past the round of 16 stage.

Belinda Bencic fought back to defeat Eugenie Bouchard in an Ostrava Open first-round contest that took over two and a half hours to settle.

Bouchard took the first set, but Bencic came from behind to advance with a 6-7 (7-9) 6-1 6-4 victory on Tuesday.

Eighth seed Jelena Ostapenko, runner-up in the Korea Open, suffered a premature exit as Aliaksandra Sasnovich consigned the former French Open champion to a 6-2 6-2 defeat.

Emma Raducanu also went out in straight sets, with Daria Kasatkina beating the 2021 US Open champion 7-5 6-4.

Catherine McNally blitzed to a 6-1 6-2 victory over Anna Blinkova, while Alycia Parks progressed past Karolina Pliskova to secure the first top-20 win of her career.

Top seed Ons Jabeur swept aside Ann Li with relative ease in a 6-2 6-3 victory at the Jasmin Open to reach the last 16.

Veronika Kudermetova, the second seed, breezed past Varvara Gracheva with a commanding 6-1 6-0 win.

Anastasia Potapova, Petra Martic, Magdalena Frech and Harriet Dart were among the other victors.

Carlos Alcaraz was dumped out of the Astana Open in the first round on Tuesday, suffering a surprise 7-5 6-3 defeat to David Goffin.

Goffin entered the draw as a lucky loser after squandering two match points to lose his final qualification match against Luca Nardi on Sunday, but he produced a fine display to see off the world number one in one hour and 46 minutes. 

The Belgian had to rediscover his composure to take the opener after throwing away a 5-2 lead, but ultimately deserved his straight-sets win over the US Open champion. 

Speaking on court after his victory, Goffin said: "I always believe that I have the level to cause some trouble against those guys. 

"When you play against the world number one on a big stage, big crowd, the fire inside gives you so much power to play your best tennis because you don't have any choice."

Stefanos Tsitsipas was the only other seed in action in Kazakhstan on Tuesday, and he advanced to the round of 16 by beating home favourite Mikhail Kukushkin 6-3 6-4.

The Tokyo Open also lost its top seed, as Casper Ruud fell to a 6-3 6-3 loss to Jaume Munar, who claimed his first top-10 win since beating Alexander Zverev in 2019.

But the likes of Borna Coric and Nick Kyrgios fared better, claiming straight-sets wins over Thanasi Kokkinakis and Tseng Chun-hsin, respectively.

Wimbledon runner-up Kyrgios only dropped four further points on his serve after being forced to save a break point in his opening service game, racing to a dominant 6-3 6-1 win.

Elsewhere, eighth seed Dan Evans fought back to beat Radu Albot 6-7 (3-7) 6-1 6-4, and Alex de Minaur lost 6-3 6-2 to Kwon Soon-woo. 

Nick Kyrgios' lawyers will apply for the tennis star's assault charge to be dismissed on mental health grounds, an Australian court was told on Tuesday.

Kyrgios was charged in July of this year in relation to the alleged assault of a former partner in January 2021.

The 27-year-old, who has enjoyed a fine season in 2022, reaching the final of Wimbledon and the last eight at the US Open, was not present for a hearing in Canberra on Tuesday, as he features in the Japan Open.

Michael Kukulies-Smith, who is representing Kyrgios, asked for the case to be adjourned so forensic mental health reports could be prepared.

The case was duly adjourned to February 3, 2023 by magistrate Glenn Theakston. It is then expected Kyrgios' legal representatives will apply to have the case dismissed, with Kukulies-Smith stating he was making the application having reviewed Kyrgios' "medical history since 2015, including public disclosures of his mental health struggles".

Australian law dictates that magistrates have the power to dismiss a charge if they believe an accused person is mentally impaired, and that dealing with a charge in such a manner would be of benefit to both the defendant and the community.

Kyrgios could face two years in prison should he be handed a maximum sentence.

Elena Rybakina advanced to the last 16 at the Ostrava Open on Monday, but fellow former grand slam winner Victoria Azarenka exited at the first hurdle.

Rybakina, who has struggled for consistency since victory at Wimbledon earlier this year, came back from a set down to dispatch Madison Keys with a 5-7 6-3 6-3 win.

She could face eighth seed Jelena Ostapenko in the next round, but one name not in the draw will be Azarenka, who could not claw back victory against Ekaterina Alexandrova in a 6-4 4-6 2-6 defeat.

Alexandrova is in line to play either Emma Raducanu or Daria Kasatkina in the next stage.

Meanwhile, top seeds Iga Swiatek and Paula Badosa earned the identity of their opponents after receiving first-round byes.

Swiatek will play Ajla Tomljanovic, who progressed in straight sets against Zhang Shuai, as Badosa faces Petra Kvitova, who was made to work a little harder in three by Bernarda Pera.

At the Jasmin Open, third, fifth and seventh seeds Alize Cornet, Elise Mertens and Katerina Siniakova each advanced with respective straight-sets routs of Laura Pigossi, Jaqueline Cristian and Chloe Paquet – the latter retiring as she trailed 4-0 in the second set.

But eighth seed Magda Linette is out after letting an early lead slip against Lucrezia Stefanini, who celebrated a 2-6 6-4 6-4 victory.

World number nine Andrey Rublev comfortably beat qualifier Laslo Djere 6-4 6-3 to secure his place in the second round of the Astana Open.

The fifth seed found a crucial break of serve when leading the opener 5-4 to take the first set in Kazakhstan, before winning the next three games to put himself in the ascendancy in the second.

And despite a desperate last stand to stay in the match from Djere, Rublev held serve three times with relative ease to finish off his Serbian opponent.

Eighth seed Felix Auger-Aliassime served 14 aces to Roberto Bautista-Agut's two in their first-round match, but it was the Spaniard who advanced with a 6-4 7-6 (8-6) success.

Meanwhile, world number 10 Hubert Hurkacz overcame Francisco Cerundolo in straight sets.

Adrian Mannarino, the runner-up in Astana in 2020, came from a set down to beat Stan Wawrinka – playing as a wildcard – 1-6 6-2 6-3, and qualifier Zhizhen Zhang romped to victory with a superb third set to seal a 4-6 6-4 6-1 comeback win of his own over Aslan Karatsev.

At the Tokyo Open, fourth seed Frances Tiafoe cruised into the second round with a 6-3 6-4 triumph over Yasutaka Uchiyama, one of three Japanese players who crashed out at the first-round stage of their home tournament.

Uchiyama's countrymen Taro Daniel and Shintaro Mochizuki also tasted defeat at the hands of Bernabe Zapata Miralles and Brandon Nakashima, respectively.

Iga Swiatek warned the tennis schedule is "not safe" and "could cause injury" as she pulled out of the Billie Jean King Cup Finals.

The world number one was due to represent Poland in an event that will be staged in Glasgow from November 8-13, but withdrew on Monday.

That competition will start just a day after the WTA Finals finish in Fort Worth, Texas.

US and French Open champion Swiatek criticised governing bodies the WTA and International Tennis Federation (ITF), who run the Billie Jean King Cup, over the calendar.

"I was thinking it through a lot and discussing it with my team, but I will not be able to play at the Billie Jean King Cup in Glasgow," Swiatek posted in an Instagram story.

"It makes me sad. I'm very sorry, because I play for Poland whenever it's possible and I always give it my best.

"Playing in Poland this year [in the qualifiers] was an honour and I hoped to do this again at the end of the season.

"I'm disappointed that tennis governing bodies didn't come to an agreement on something as basic as the calendar of tournaments, giving us only one day to travel through the globe and changing the time zone.

"The situation is not safe for our health and could cause injury."

Novak Djokovic scooped his 89th career title with victory over Marin Cilic in Sunday's Tel Aviv Open final.

Playing his first singles event since winning Wimbledon in July, Djokovic landed a 6-3 6-4 victory, improving his career head-to-head winning record to 19-2 against former US Open champion Cilic.

He broke serve to lead 3-1 in the opening set, and then struck immediately in the second set to tighten his grip on the contest, completing the task with a service winner on his first championship point.

This indoor hard-court success goes down as a third title of the year for Djokovic, who won the Internazionali d'Italia on clay before triumphing on the Wimbledon grass. He is the first man to win a title on all three surfaces in 2022 at ATP Tour level.

Prevented from playing the North American hard-court stretch of the season, due to his refusal to accept a COVID-19 vaccination, Djokovic sat out the US Open.

He made his first post-Wimbledon appearance at the invitational Laver Cup team event in London last week, which doubled up as Roger Federer's retirement party.

At the age of 35, Djokovic hopes to be a presence on tour for a good while to come, and Sunday's straight-sets picking apart of Cilic was a fresh demonstration of his enduring prowess.

Marc-Andrea Husler beat world number 31 Holger Rune 6-4 7-6 (10-8) to become the Sofia Open champion and earn his first tour-level title.

Rune reached Sunday's decider with a semi-final triumph over top seed Jannik Sinner, who was bidding to win three straight titles in Sofia.

But it was Husler who took the first set, breaking his Danish opponent in the first game of the match before holding in all five of his service games to clinch the opener.

The second set was another tight affair, as both players continued to dominate on their serve. However, the match hit a crucial juncture with Rune leading the second set 6-5, as he spurned two set points to break Husler and level the final up.

Husler survived to take the second set to a tie-break, though Rune again had the opportunity to make it one set apiece as he failed to convert another two set points in the tie-break.

And Husler took advantage with two crucial breaks of Rune's serve to seal the victory and become the first Swiss player to win an ATP Tour title since Roger Federer in 2019.

"I am completely taken aback," Husler said in his on-court interview.

"I am lost for words. It was a great match. I played a great, great match for sure. I just tried to stay focused, stayed calm and I am just really happy I was able to make it."

Barbora Krejcikova claimed her first title of the year by beating top seed Anett Kontaveit in the inaugural Tallinn Open final on Sunday.

Krejcikova had not won a singles title since her third triumph of 2021 in Prague last July, but ended her drought with a 6-2 6-3 defeat of the top seed.

The Czech ended the home favourite's hopes of being crowned champion in a showpiece match that was over in an hour and 21 minutes.

Kontaveit had won 24 consecutive indoor matches on hard courts, but she was no match for the 2021 French Open champion.

Krejcikova won 71 per cent of points on Kontaveit's second serve, breaking twice in the opening set and three times in the second.

She drew first blood to go 4-2 in the first following precise groundstrokes off both wings, then broke for a second time to seal an opening set in which Kontaveit made 13 unforced errors.

World number four Kontaveit responded with a break in the opening game of the second set, but failed to back that up with a hold.

Kontaveit had the initiative again at 3-1, but there was a sense of deja vu as her opponent broke straight back and served out the match after moving 5-3 in front with another break.

Yoshihito Nishioka produced an impressive display to shock Denis Shapovalov in the Korea Open final and win his first ATP Tour title in four years.

The Japanese player earned a 6-4 7-6 (7-5) triumph in a competitive contest against fourth seed Shapovalov on Sunday that lasted just under two hours.

Victory gave Nishioka his first trophy since the Shenzhen Open in 2018 and capped a memorable week that also saw him defeat top seed Casper Ruud at the ATP 250 event in Seoul.

Nishioka took a big step towards the second title of his career by breaking Shapovalov at a crucial moment when he was 5-4 up in the opener, both players having earlier saved break points.

His Canadian opponent was in the ascendancy after claiming an early break in the second set but Nishioka fought back from 3-1 down to force a tie-break and then won four of the first five points in the breaker.

Despite Shapovalov reducing the deficit, he was consigned to defeat when he sent a forehand wide, Nishioka dropping to his knees in delight after converting his second match point.

Shapovalov, a Wimbledon semi-finalist last year, has now lost in four consecutive ATP final appearances and still has just one career title to his name.

Novak Djokovic is yet to drop a set at the Tel Aviv Open as he reached the final with a 6-1 7-6 (7-3) success over Roman Safiullin.

The Serb broke his Russian opponent twice as he cruised to the opening set, and though Safiullin took the 21-time grand slam champion to a tie-break in the second, Djokovic's class showed as he won the tie-break 7-3 to ensure his place in Sunday's decider.

It was far from plain sailing for Djokovic, who conceded the tension in the second set was hard to handle.

Djokovic said: "I think it was a very competitive match, especially in the second set.

"I must say I was quite emotional on the court today in the second set, there was a lot of tension, and that was also due to his aggressive style of tennis. Big serves, and when he has time, he's so solid from the forehand and backhand corner.

"I knew that I had to stay very strong, and that he was definitely going to raise his level in the second set, which happened. I was serving for the match and played a couple of loose points, but credit to him for fighting back. It was an enjoyable evening on the court for sure."

Marin Cilic secured his spot as Djokovic's final opponent with a comfortable straight sets triumph over Constant Lestienne.

The Croatian second seed served 14 aces as he eased to victory in under two hours, winning 11 out of his 12 first-serve points en route to a 7-5 6-3 win.

Holger Rune is into the Sofia Open final after Jannik Sinner was forced to retire through injury with the Dane leading 5-7 6-4 5-2.

Sinner won the opening set but lost the second, and with Rune just one game away from winning the match, the top seed chose to retire with ankle pain, putting an end to his hopes of winning three straight titles in Sofia.

Rune will face Marc-Andrea Huesler in the final, after the world number 95 upset fourth seed Lorenzo Musetti.

The first set went to a tie-break as neither could find a break of serve, though Musetti found two in the tie-break to help him to a 5-1 lead.

However, the Italian surrendered the next six points as Huesler pulled off an incredible comeback to take the first set.

The second set was another tight affair as both held serve after serve, but Huesler finally found a crucial break to prevail 7-6 (7-5) 7-5.
