Novak Djokovic will face Nick Kyrgios in a practice match ahead of the Australian Open.

Djokovic marked his return to Australia by beating Sebastian Korda to win his 92nd Tour-level title on Sunday in Adelaide.

Kyrgios, meanwhile, did not feature in the inaugural United Cup for Australia after withdrawing due to injury.

They will now meet in a practice match at Rod Laver Arena on Friday, ahead of the season's first grand slam.

Ticket proceeds will go to the Australian Tennis Foundation.

The duo have had a turbulent relationship in the past, though last year appeared to be on better terms.

Kyrgios came to Djokovic's defence when the Serbian was denied entry to Australia and subsequently deported ahead of the 2022 Australian Open due to his COVID-19 vaccination status.

Australia's policy on non-vaccinated individuals entering the country has now changed, and Djokovic had his three-year suspension from the nation revoked, allowing him to compete in Melbourne this year.

Krygios has a 2-1 record against Djokovic, though both of his wins came back in 2017.

They last met in the final of Wimbledon last year, with Djokovic coming out on top 4-6 6-3 6-4 7-6 (7-3).

Novak Djokovic battled back from match point down to win his first tournament of the year with a thrilling victory over Sebastian Korda in the final of the Adelaide International 1.

The 35-year-old certainly did not have it all his own way as the American gave a brilliant account of himself, but Djokovic had the nous to get his 92nd tournament win over the line 6-7 (8-10) 7-6 (7-3) 6-4.

During a gruelling encounter that lasted three hours and 11 minutes, there was precious little to separate them with only three breaks of serve in total.

Two of those came in the first set. Korda had the initial advantage, a gorgeous backhand down the line punishing a stranded Djokovic, but he instantly hit back as his opponent found the net with what looked a routine shot.

The subsequent tie-break was similarly neck-and-neck until a Djokovic slice went long and then he put another return into the net to hand Korda the set, the Serbian venting his frustration at his team at the interval.

Korda then had the opportunity to win the championship towards the end of the second set, but Djokovic worked the situation bravely before a smashed volley emphatically saved him, with another tie-break soon arriving.

Djokovic surged into a 6-1 lead and eventually grasped his third set point, and from then on there only looked like being one winner, with the 21-time grand slam champion pouncing on his first break point in the decider to take the win.

This tournament was of course Djokovic's first in Australia since being deported ahead of the 2022 Australian Open due to his unvaccinated status.

Upon his return to the country where he has won nine grand slams, Djokovic was feeling the love.

"It's been an amazing week and [the fans] made it even more special. For me to be standing here is a gift, definitely," Djokovic said in the trophy ceremony.

"I gave it all today and throughout the week in order to be able to get my hands on the trophy.

"The support that I've been getting in the past 10 days is something that I don't think I've experienced too many times in my life, so thank you so much [to] everyone for coming out every single match."

Success ensured Djokovic levelled Rafael Nadal (92) for fourth-most men's singles titles in the Open Era, with only Ivan Lendl (94), Roger Federer (103) and Jimmy Connors (109) winning more.

Taylor Fritz claimed the deciding victory as the United States stormed into an unassailable 3-0 lead over Italy in the United Cup final.

Jessica Pegula and Frances Tiafoe paved the way for Fritz to be the hero with their victories over Martina Trevisan and Lorenzo Musetti earlier in Sunday's final in Sydney.

While Musetti retired hurt while trailing 6-2, WTA world number three Pegula dispatched Trevisan in straight sets, carrying on the form that saw her defeat Iga Swiatek in the USA's semi-final win over Poland.

And Fritz ensured that the inaugural United Cup went his nation's way with a 7-6 (7-4) 7-6 (7-6) win over Matteo Berrettini, who clawed back the first championship point but was unable to prevent his opponent taking the second.

"It's great. It’s amazing for the team to win this event. We came in with really high hopes, or at least I did, for the event," said Fritz, who is ranked ninth in the world by the ATP after winning three titles in 2022.

"I was really happy to be in that position to clinch the match."

There were jubilant scenes as the USA team rushed to celebrate with Fritz, though Tiafoe was perhaps slightly overzealous.

"Just the emotions when you win and everyone comes running at you, it’s amazing," Fritz said. "I don’t know if you saw the replay but Frances basically headbutted me!"

Tallon Griekspoor clinched his first ATP Tour title by fighting back to beat Benjamin Bonzi 4-6 7-5 6-3 in Saturday's final at the Tata Open Maharashtra in Pune.

Both Griekspoor and Bonzi were taking part in their first Tour-level final after strong campaigns in India, and it was the Frenchman who took the opener, holding firm before clinching the vital break in the 10th game.

The crucial game came at the same point in the second set, with Griekspoor converting his second break point of a back-and-forth game to snatch the momentum before levelling things up.  

Griekspoor was on top from there, breaking again in the third game of a tight decider – in which he was forced to save a further two break points – before repeating the trick to finish the job.

Asked how he mustered his response after a disappointing start, the Dutchman said: "I don't know. I think even in the first set I played well, I just played two bad games and made it hard for myself.

"All I did was keep fighting for every point, keep trying to play my best tennis. It worked out well, it was all good in the end.

"There were more nerves than usual, but it wasn't too bad. We both played really well with our service games. The nerves are always there, but I'm pleased with how I handled it today." 

Novak Djokovic clinched a 6-3 6-4 win against Daniil Medvedev in the Adelaide International semi-finals on Saturday, overcoming an injury scare to tee up a final meeting with Sebastian Korda. 

Djokovic made a fast start by breaking in Medvedev's second service game, though there was concern when the 21-time grand slam winner required a lengthy medical timeout at 5-2 up in the opening set.

With Djokovic's long-awaited return to the Australian Open just over a week away, the sight of the Serbian clutching his left hamstring was an unwelcome one, but he eventually returned to the court to take the opener 6-3.

Having shown his staying power in a low-key start to the second set, Djokovic claimed the vital break following some excellent work at the net in the seventh game, though Medvedev was ultimately the master of his own downfall after producing a double fault at break point.

Djokovic then faced break point in the next game as Medvedev desperately tried to claw his way back into the contest, but a huge second serve eventually saw him hold off the Russian, who was unable to trouble him thereafter.

Speaking court-side after teeing up his 131st ATP Tour final, Djokovic played down concerns over his hamstring issue, saying: "Thankfully, it was nothing too serious. 

"If it was, I wouldn't have been able to continue. I just tried with a medical timeout and some anti-inflammatories and I just settled in.

"The more the match went on, the more my hamstring was warmer, I guess, and bothering me less. So hopefully tomorrow it will be okay."

Asked whether he considered retiring in order to save himself for the first grand slam of the year, Djokovic added: "I can't say it didn't cross my mind today on the court. 

"But you just can't calculate on the court. At this stage of my career, every match counts, every match is a present in a way, so I just try to give my best and win wherever I am."

Yoshihito Nishioka also struggled with an injury in the day's other semi-final, but the world number 36 was less fortunate than Djokovic as he retired midway through his clash with Korda.

Korda took a close opening set via a tie-break after Nishioka ranted at a second umpire in as many days, raging when a point was replayed following an error from a line judge.

Nishioka saw his serve broken in the first game of the second set before calling a medical timeout after seeming to struggle with a leg injury, and his subsequent retirement ensured Korda advanced to his fifth ATP Tour final.

Lucia Bronzetti downed Valentini Grammatikopoulou to seal Italy's place in the final of the inaugural United Cup.

Despite losing to Poland in their City Final in Brisbane, Italy claimed a place in the Sydney play-offs as the best-placed runner-up.

Having led 2-0 overnight, Italy were pegged back by Stefanos Tsitsipas' battling 4-6 7-6 (7-2) 6-4 win over Matteo Berrettini.

That put the pressure on Bronzetti's meeting with world number 199 Grammatikopoulou.

Yet despite losing her two previous matches against Grammatikopoulou, world number 54 Bronzetti made no mistake, cruising to a 6-2 6-3 victory.

Italy will now face the United States, who beat Poland 5-0 in their semi-final, in the final on Sunday.

Iga Swiatek was in tears after losing to Jessica Pegula as the United States took a 2-0 United Cup semi-final lead over Poland, while Italy moved into command against Greece on Friday.

World number one Swiatek was beaten 6-2 6-2 by the impressive Pegula in just 71 minutes at Ken Rosewall Arena.

Swiatek got the better of Pegula three times last year, but the American made light work of seeing off the three-time grand slam champion this time around to put USA in front.

Pegula struck 21 winners, attacking the Swiatek serve in a commanding display just over a week before the Australian Open gets under way.

Swiatek's emotions came out after she was emphatically defeated by the world number three in Sydney.

Pegula said: "I played her today, conditions are totally different than anywhere else I played her. Obviously maybe I had a little bit of an advantage, they just flew in yesterday.

"Definitely the fastest conditions I have played her [in]. Every other place I've played her has been pretty slow. I think that favoured me a lot, and I was able to use that to my advantage and play a really super clean match.

"I think I just was able to execute my game plan probably better than I have previous times."

Frances Tiafoe backed up Pegula's win by beating Kacper Zuk, who replaced the unwell Daniel Michalski, 6-3 6-3.

That ensures Taylor Fritz has a chance to put the United States into the final if he beats Hubert Hurkacz on Saturday.

Italy are in control of the other semi-final following victories for Martina Trevisan and Lorenzo Musetti.

Trevisan upset Maria Sakkari 6-3 6-7 (4-7) 7-5 before Musetti outclassed Stefanos Sakellaridis, winning 6-1 6-1.

Iga Swiatek dragged Poland into the semi-finals of the United Cup with inspired performances in her singles and doubles matches against Italy.

Poland trailed after Lorenzo Musetti and Matteo Berrettini secured wins against Daniel Michalski and Hubert Hurkacz respectively, only for Swiatek and Magda Linette to level things with respective singles victories over Martina Trevisan and Lucia Bronzetti.

That sent the Brisbane city final to a decider in the mixed doubles, which Swiatek and Hurkacz won with ease 6-1 6-2 against Musetti and Camilla Rosatello, though there was a pause in the second set to dry rainfall on the court.

Despite defeat, Italy also advanced to the final four as the city finals loser with the best record.

It was more routine in Sydney as the United States eased to a 4-1 win against Great Britain.

Madison Keys came from a set down to beat Katie Swan, while Jessica Pegula eased past Harriet Dart 6-2 6-0 after Cameron Norrie had defeated Taylor Fritz in three sets.

Despite going a set behind, Frances Tiafoe came back to beat Dan Evans 3-6 7-5 6-3 to clinch the win for his country, before Pegula and Fritz added some gloss after beating Dart and Evans in the mixed doubles.

The third city final in Perth included a thriller as Greece's Stefanos Tsitsipas beat Borna Coric 6-0 6-7 (4-7) 7-5. Donna Vekic had no trouble getting Croatia on the board as she eased past Despina Papamichail 6-2 6-0.

Maria Sakkari put Greece 2-1 ahead when she beat Petra Martic 6-3 6-3, but Borna Gojo defeated Stefanos Sakellaridis in straight sets to make it 2-2.

However, Greece secured the win and their place in the last four after the pairing of Sakkari and Tsitsipas saw off Martic and Gojo 7-6 (8-6) 6-4.

Greece will take on Italy in the semi-finals, while Poland face the USA, with both taking place in Sydney on Friday.

Dan Evans helped Great Britain reach the last eight of the inaugural United Cup as his 6-3 1-6 6-3 win over Albert Ramos-Vinolas decided the team's Group D tie against Spain.

Rafael Nadal's shock defeat to Cameron Norrie – coupled with Katie Swan's win against Nuria Parrizas-Diaz – put Spain 2-0 down in the best-of-five tie ahead of Sunday's action.

World number 13 Paula Badosa put them back into contention with a hard-fought 6-7 (6-8) 7-6 (7-5) 6-1 win against Harriet Dart, but Evans gave Britain an unassailable lead by battling past Ramos-Vinolas, recovering from a dismal second set.

Having topped Group D, Britain will face the Croup C winners – the United States, Germany or the Czech Republic – for a semi-final place on Wednesday.

Meanwhile, Hubert Hurkacz doubled up to help Poland past Kazakhstan, teaming up with Iga Swiatek in the mixed doubles after beating Alexander Bublik.

Hurkacz beat Bublik 7-6 (8-6) 4-6 6-3 in just over two hours before Magda Linette overcame Zhibek Kulambayeva 6-2 6-1.

With Poland's first win in the competition secure, world number one Swiatek helped Hurkacz put the icing on the cake with a 6-3 6-4 victory against Kulambayeva and Grigoriy Lomakin.

The Czech Republic also enjoyed a fruitful day as two-time Wimbledon champion Petra Kvitova downed Laura Siegemund in straight sets to seal the team's win against Germany, but Casper Ruud was less fortunate, with Norway losing their tie against Brazil despite his success against Thiago Monteiro.

Rafael Nadal's United Cup campaign began with defeat against Cameron Norrie as Great Britain established a 2-0 lead over Spain in Group D.

The 22-time grand slam winner surrendered a first-set lead before going down 3-6 6-3 6-4 against the world number 14, who secured his first victory in five meetings.

Norrie, who became only the second Briton after Andy Murray to beat the Spaniard, set the tone for his team, with Katie Dart also coming from behind to deny Nuria Parrizas Diaz 3-6 6-1 6-2 later on.

Meanwhile, Germany's Alexander Zverev lost in straight sets on his return to ATP action, going down 6-4 6-2 to Jiri Lehecka of the Czech Republic, who went 2-0 up in the tie after Marie Bouzkova defeated Jule Niemeier 6-2 7-5.

World number one Iga Swiatek got Poland off to a flying start against Kazakhstan in Brisbane with a commanding 6-1 6-3 victory over Yulia Putintseva, but defeat for Daniel Michalski against Timofey Skatov leaves the Group B tie finely poised.

Brazil enjoyed a flawless start against Norway in Group E. Beatriz Haddad Maia was a 6-4 6-2 winner over Malene Helgo, and Felipe Meligeni Alves overcame Viktor Durasovic 6-3 6-3.

The spoils were shared between Belgium and Bulgaria in Group A with Alison van Uytvanck beating Isabella Shinikova, before David Goffin was seen off by Grigor Dimitrov 6-4 7-5.

Croatia closed the day with a pair of victories against Argentina in Group F as Donna Vekic and Borna Coric defeated Maria Carle and Francisco Cerundolo respectively.

Maria Sakkari sealed victory for top-seeded Greece over Bulgaria in the United Cup with a straight sets win over Viktoriya Tomova.

Team-mates Stefanos Tsitsipas and Despina Papamichail had already won their matches on Thursday, and Sakkari's 6-3 6-2 triumph gave Greece an unassailable 3-0 lead.

Michail Pervolarakis was defeated by Dimitar Kuzmanov in the final singles match between the nations, but Tsitsipas and Sakkari teamed up to earn Greece a 6-4 6-4 success in the doubles encounter to end on a high.

World number 16 Matteo Berrettini helped Italy topple Brazil by overcoming Thiago Monteiro 6-4 7-6 (9-7).

That gave Italy a 2-1 lead, and Lucia Bronzetti finished the job by demolishing Laura Pigossi in straight sets, with Brazil powerless to overturn the deficit despite Berrettini and Camilla Rosatello's defeat in the doubles match.

US Open semi-finalist Frances Tiafoe clinched a win for the United States over the Czech Republic after opponent Tomas Machac retired with an ankle injury with the score at 6-3 2-4.

Petra Kvitova had defeated Jessica Pegula 7-6 (8-6) 6-4 in the third singles match to give Czech Republic hope, but Tiafoe's win settled the contest before Pegula and Taylor Fritz joined up for success in the doubles.

Great Britain were 3-2 victors over Australia despite a pair of defeats on day two in Sydney.

Cameron Norrie's triumph over Nick Kyrgios' replacement Alex De Minaur on day one had helped Great Britain to a 2-0 lead over the hosts, and Harriet Dart prevailed over Maddison Inglis to wrap up the victory.

Dan Evans was then beaten 6-3 7-6 (7-3) by Jason Kubler before Dart and Jonny O'Mara fell to defeat in the doubles, but Great Britain's strong start saw them through.

France and Switzerland completed 5-0 sweeps of Argentina and Kazakhstan respectively, with Caroline Garcia winning both her singles and doubles matches in straight sets while Stan Wawrinka saw off Alexander Bublik 6-3 7-6 (7-3).

Stefanos Tsitsipas opened his United Cup campaign with a comeback victory over Grigor Dimitrov in Perth.

ATP world number four Tsitsipas is one of the headline names in action at the event, which is acting as a warm-up tournament for the Australian Open.

After going a set down to his Bulgarian opponent in his first game of the inaugural tournament, Tsitsipas hit back with a strong second set before holding his nerve in a tense tie-break in the decider, securing a 4-6 6-2 7-6 (7-4) win.

Tsitsipas's team-mate Despina Papamichail continued Greece's strong start, also coming from a set down to beat Isabella Shinikova 3-6 6-4 6-1.

Great Britain opened with a pair of victories, Cameron Norrie and Katie Swan earning straight sets triumphs over their Australian counterparts in Sydney.

Norrie, who was initially set to play Nick Kyrgios prior to the Wimbledon finalist's withdrawal due to an ankle injury, eased to a 6-3 6-3 victory over Alex De Minaur, while Swan defeated Zoe Hives. 

The United States are also taking a 100 per cent record into day two of the tournament, after Taylor Fritz and Madison Keys overcame Jiri Lehecka and Marie Bouzkova respectively, while France pair Arthur Rinderknech and Alize Cornet got off to winning starts against Argentina's Francisco Cerundolo and Maria Lourdes Carle.

In Brisbane, Swiss hope Belinda Bencic secured a 7-6 (7-0) triumph over Yulia Putintseva of Kazakhstan and Beatriz Haddad Maia, the Brazilian world number 15, dispatched Italy's Martina Trevisan 6-2 6-0.

Novak Djokovic is hoping for a positive crowd reception at the upcoming Australian Open after his deportation prior to the 2022 tournament.

Djokovic is a nine-time Australian Open winner and will be looking to etch his name on the trophy once again in the first grand slam of 2023.

The Serbian was banned from playing at the most recent edition after he was deported due to his refusal to be vaccinated against COVID-19, despite being initially granted a medical exemption.

As a result, Djokovic missed out on the opportunity to lift a record-extending 10th title, as long-time rival Rafael Nadal won the tournament in his absence.

There had been concerns over Djokovic's ability to play in Melbourne this time around, but a change in border entry rules means travellers are no longer required to provide evidence of their vaccination status.

The incident earlier in 2022 did not go down well with some sections of the Australian public, but Djokovic is hoping to receive a warm reception when he takes to the court in Adelaide and then Melbourne.

"I'm hoping everything is going to be positive," Djokovic said at a press conference. "Obviously it's not something I can predict.

"I'll do my best to play good tennis and bring good feelings and emotions to the crowd. This is what we do as professional athletes, we are also entertainers in a way. We try to make people feel good, have fun and go home and have good memories.

"Hopefully that's going to happen with me. I don't know how many matches I'll play but I'm hoping I can go all the way."

As well as the Australian Open, Djokovic's vaccination status also prevented him from competing at Flushing Meadows, and the memories of how he was treated still linger in Djokovic's mind.

The world number five explained: "Obviously what happened 12 months ago was not easy for me, for my family, team, anybody who is close to me. It's obviously disappointing to leave the country like that.

"You can't forget those events. It's one of these things that stays with you for I guess the rest of your life.

"It's something that I've never experienced before and hopefully never again. But it is a valuable life experience for me and something that as I said will stay there but I have to move on. Coming back to Australia speaks [to] how I feel about this country, how I feel about playing here."

Djokovic is drawing on his impressive record in Australia, as he prepares for the grand slam by taking part in the Adelaide International.

"It's great to be back in Australia," he added.

"It's a country where I've had tremendous success in my career, particularly in Melbourne. It's by far my most successful grand slam.

"The good memories and history I have on Australian soil gives me a lot of positive emotions and belief I can do it again and go far.

"I always have faith in myself and belief I can win every tournament I play in, with the career I've had I deserve to have that kind of mental approach."

Djokovic also confirmed he had split from physio Uli Badio after over five years of working together.

The 35-year-old will instead be using the services of Claudio Zimaglia, who most recently worked with Brandon Nakashima.

Novak Djokovic's imminent return to the Australian Open will be good for tennis, according fellow great Rafael Nadal.

Djokovic arrived in Australia this week and will compete in the first of two Adelaide International tournaments before the opening grand slam of 2023 begins on January 16.

In January this year, the 21-time grand slam winner was deported from Australia after being prevented from participating at the last edition of the event, having initially been granted a medical exemption to enter the country despite not being vaccinated against COVID-19.

There were concerns Djokovic would then be banned from entering Australia again, but a change in border entry rules means travellers are no longer obliged to provide evidence of their vaccination status.

While Djokovic's presence may represent a blow to Nadal's hopes of defending the title he clinched in the Serbian's absence last year, the Spaniard is pleased to see him taking part.

"Novak is here, it's good for tennis, probably good for the fans," Nadal said. "Let's see. [Having the] best players on court is always better."

Meanwhile, 22-time grand slam champion Nadal saw his former long-time rival Roger Federer retire this year, but he is not looking to follow suit despite being plagued by injuries in recent months.

Asked whether his upcoming appearance at the Australian Open could be his last, the 36-year-old said: "As a professional, you never know. Hopefully not.

"I mean, when you are at the age of 36, you never know when it's going to be the last one. It's obvious, but I don't like to talk about that because I am not in that mood now.

"I'm just focused on trying to play at the highest level possible and giving myself a possibility to keep being competitive, to fight for anything.

"That's my goal now, I'm not thinking about it being my last time here. If that's the last time, let's try to enjoy it as much as possible and try to create something special.

"I am happy doing what I am doing. I'm looking forward to still doing this."

Novak Djokovic wants to play for as long as his body is able as he aims to emulate Rafael Nadal and Roger Federer after coming through a challenging 2022 campaign.

Djokovic began last season in somewhat controversial circumstances after he was barred from the Australian Open for his stance on vaccination for the global coronavirus pandemic.

The 21-time grand slam champion lost his world number one spot after failing to defend his French Open crown but roared back to glory at Wimbledon.

A record-matching fifth ATP Finals title took him level with the recently retired Federer and 35-year-old Djokovic has no intentions of slowing down in the new year.

"I would like to play as long as I possibly can," he stated in Dubai on Friday. "I don't have really any number in my head.

"Things are progressing so far pretty well for me. I can't complain. So as long as I play at this level, as long as I have the fire, I'll keep going."

Djokovic may have been unceremoniously deported from Australia earlier this year amid the fallout over his vaccination status but he has enjoyed playing at the first grand slam of the year in recent seasons.

At no other grand slam event has the Serbian been more prolific, with nine titles to date, and he is relishing the chance to start his season in Melbourne once more.

"I'm just glad to have a chance to start there," he added. "My record has been pretty decent over the years in Australia. So I look forward to going there.

"I always ask for the best for myself. Over the years, I've been really fortunate to start very strong in Australia and love playing there.

"After obviously what happened earlier this year, hopefully, I can have a decent reception there, and that can help me play some good tennis."
