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.

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.

Novak Djokovic took just an hour and 15 minutes to win his first singles match in Australia since 2021, beating Constant Lestienne 6-3 6-2 at the Adelaide International on Tuesday.

Djokovic – who saw a three-year visa ban lifted in November – played with Vasek Pospisil in the doubles on Monday, but this was his first singles outing in the country since his vaccine-related absence from last year's Australian Open.

"For the first match [of the season] I can't complain," Djokovic said. "I played very well. I thought the first six games were very competitive and I have never faced him before.

"But once I made that break at 3-2 in the first set I thought I stepped it up and played really good tennis for the rest of the match."

Elsewhere in Adelaide, third seed Daniil Medvedev advanced after Lorenzo Sonego retired hurt with the Russian leading by a set, while sixth seed Jannik Sinner eased past Kyle Edmund 6-3 6-2.

Seventh seed Denis Shapovalov is also through after coming from a set down to beat Rinky Hijikata, but fourth seed Andrey Rublev is out after losing to Roberto Bautista Agut in three sets.

The Spaniard will face Sebastian Korda next after he beat Andy Murray 7-6 (7-3) 6-3, while eighth seed Karen Khachanov advanced after beating Pedro Cachin 6-2 6-4. 

At the Maharashtra Open in Pune, Aslan Karatsev had no problems seeing off Pablo Andujar 6-1 6-3, with the eighth seed set to face Tim van Rijthoven in the last 16 after the Dutchman beat Radu Albot 6-4 6-4.

There were also wins for Maximilian Marterer against Elias Ymer and Pedro Martinez against Ramkumar Ramanathan.

Novak Djokovic was beaten in his first match back in Australia but did at least receive a warm reception from the crowd at the Adelaide International.

Djokovic – who saw a three-year visa ban lifted in November – was playing with Vasek Pospisil in the doubles, and the duo lost 4-6 6-3 10-5 to Tomislav Brkic and Gonzalo Escobar on Monday, but the fans in attendance chanted "Novak" as they welcomed him back following his absence from last year's Australian Open.

The Serbian will face Constant Lestienne in the first round of the men's singles, but second seed Felix Auger-Aliassime is already out after he lost to Alexei Popyrin.

Auger-Aliassime struggled throughout as his Australian opponent, ranked 120th in the world, put in a crowd-pleasing performance to go through 6-4 7-6 (7-5).

Another young star, Holger Rune, is also out after the fifth seed was beaten 2-6 6-4 6-4 by Yoshihito Nishioka.

Quentin Halys set up a potential second-round clash with Djokovic after beating Jordan Thompson in straight sets, while Miomir Kecmanovic, Jack Draper, Roman Safiullin and Thanasi Kokkinakis all progressed.

It was also a bad day for seeds at the Maharashtra Open in Pune, with Alex Molcan beaten 6-2 6-4 by Laslo Djere and Jaume Munar losing 6-4 7-5 to Tallon Griekspoor.

Dutchman Griekspoor will now play Marco Cecchinato after the Italian overcame Nikoloz Basilashvili, and Roberto Carballes Baena set up a last-16 clash against top seed Marin Cilic by defeating fellow Spaniard Bernabe Zapata Miralles.

Filip Krajinovic did make it through a tussle with home favourite Sumit Nagal to set up a meeting with Michael Mmoh, while Benjamin Bonzi will face third seed Emil Ruusuvuori after beating Tseng Chun-hsin.

Lorenzo Musetti planned a pizza celebration after landing his second title of 2022 by seeing off Matteo Berrettini in an all-Italian final at the Napoli Cup.

The 20-year-old, who won his first ATP Tour trophy on clay in Hamburg in July, scored a 7-6 (7-5) 6-2 victory over an injury-hampered opponent.

After defying advice from his team to abandon his semi-final on Saturday, Berrettini, bothered by a foot problem, showed up for Sunday's title match and generally moved well but could not prevent Musetti getting his hands on the trophy.

Musetti's win at the hard court event saw him match Berrettini – twice a champion during the grass season –  on two titles this year. 

They are the only Italians with multiple ATP singles titles in 2022, with Musetti now increasingly close to joining compatriots Berrettini and Jannik Sinner inside the top 20.

This win nudges him a place to number 23 in the rankings, a new career-high position, and it made Musetti the ninth player on the men's tour to win a tournament this year without dropping a set at any point.

Speaking in an on-court ATP interview, Musetti said: "It was a really tough first set. Really long and we never broke.

"Matteo is a competitor; even if he was not 100 per cent physically, his capacity to stay until the end, to fight until the end, was a big problem for me to solve.

"Today I think I played not the best tennis, because I think we were both really emotional, really nervous and there was a lot of tension, but in the important moments I played better.

"It's really nice to be here with my family, with the crowd, and it's a really big win for me and an important moment for my career.

"I hope to enjoy and celebrate with great pizza. I will probably enjoy a Pizza Margherita for sure, like Napoletana."

Holger Rune surprised top seed Stefanos Tsitsipas with a straight-sets victory in Sunday's Stockholm Open final to land his second ATP title.

Still just 19, Rune added to his maiden crown in Munich five months ago with a 6-4 6-4 triumph over world number five Tsitsipas in a match lasting 95 minutes.

Tsitsipas, who was seeking a 10th ATP title and a third this season, had not dropped a set in his previous three matches en route to the final.

However, he was broken in the third game of both sets against Rune, who is the second teenager after Carlos Alcaraz to win multiple ATP titles in 2022.

Rune fired 20 winners and saved the only break point he faced – that coming in the sixth game of the second set – on his way to becoming the first Danish champion in this event.

"It was an unbelievable match from my side," Rune said in his on-court interview. "I knew it was going to be difficult, but I just tried to stick to the game plan. 

"I had to play my best tennis today, and it was good that I could find the level. I am super happy. It was very close to perfection. 

"I was making a lot of returns and playing pretty well behind my serve. Stefanos is an amazing player, who always makes it difficult. It was a super fun match to play."

Felix Auger-Aliassime clinched the European Open title by beating Sebastian Korda in straight sets in Antwerp, replicating last week's Firenze Open triumph to maintain his strong run of form.

Auger-Aliassime swept aside J. J. Wolf to emerge victorious in Italy a week ago, and was in control from the start on Sunday as he beat another American to win his third ATP title of the year.

The Canadian seized the initiative when he broke Korda's serve to go 4-2 up in the opener, before saving two break points early in the second set.

Korda failed to conjure up another opportunity to break as Auger-Aliassime wrapped up a routine 6-3 6-4 win by holding to love.

Auger-Aliassime has responded brilliantly to his first-round exit at the Astana Open earlier this month, winning eight consecutive matches – six of them in straight sets.

Meanwhile, the 22-year-old has now won three of his past four ATP Tour finals, failing to drop a set in any of those victories after losing each of his first eight final appearances.

Auger-Aliassime's victory also represented a major boost to his hopes of reaching next month's ATP Finals in Turin, strengthening his grip on the final qualification spot for the tournament.

Matteo Berrettini is set to tackle Davis Cup team-mate Lorenzo Musetti in an all-Italian Napoli Cup final on Sunday after defying advice to pull out with a foot injury.

Former Wimbledon runner-up Berrettini beat American Mackenzie McDonald 3-6 7-6 (7-2) 6-3 at the hard court event, while Musetti came through 6-3 6-4 against Serbian Miomir Kecmanovic.

Providing Berrettini is healthy to participate in the final, the tournament looks set to deliver a crowd-pleasing trophy match, but it was touch and go whether the Rome native would get through the McDonald match.

"I don't even know how I did it," Berrettini said. "I wasn't feeling very good. I asked for the physio because my foot was hurting. It happened so many times in my career that I had to fight through so many things, not just thinking about the tennis ball."

He added, quoted by the ATP: "I didn't want to retire. My team told me, 'I think you should stop'. But I tried and I found a way."

Berrettini and Musetti have never gone head-to-head before. Berrettini has won two titles this year, both on grass, in Stuttgart and at London's Queen's Club, while 20-year-old Musetti scooped his maiden ATP title on clay in Hamburg.

At the European Open in Antwerp, Sunday's final will see American Sebastian Korda tackle Canadian Felix Auger-Aliassime, in a battle of two in-form players.

Korda was runner-up last week in Gijon, while Auger-Aliassime took the title in Florence, adding to his Rotterdam triumph from February.

Korda wrestled his way past a recently resurgent Dominic Thiem, scraping a 6-7 (4-7) 6-3 7-6 (7-4) victory, before Auger-Aliassime was given a mighty battle by veteran Frenchman Richard Gasquet, winning through in two tight sets, 7-6 (7-2) 7-6 (7-3) his margin.

Like Berrettini and Auger-Aliassime, Greece's Stefanos Tsitsipas has a third title of the year in his sights this weekend.

Tsitsipas swept through to the final of the Stockholm Open with a 6-2 6-2 win over Finland's Emil Ruusuvuori, setting up a clash with 19-year-old Danish player Holger Rune.

For Rune, there was no such straightforward path into the final as Alex de Minaur pushed him all the way, with the Australian eventually edged out 4-6 7-6 (7-1) 7-5 after two hours and 50 minutes.

Dominic Thiem saved three match points before beating Hubert Hurkacz for the first time to reach the semi-finals of the European Open on Friday.

Thiem was on the brink of being knocked out by the top seed in Antwerp, but fought back to win 3-6 7-6 (11-9) 7-6 (7-4).

The 2020 US Open champion fended off all three match points in a second-set tie-break to take a thrilling quarter-final the distance and then came out on top in another breaker to advance.

Thiem will do battle with Sebastian Korda for a place in the final after the American emphatically defeated eighth seed Yoshihito Nishioka 6-0 6-2.

Richard Gasquet moved into the last four at the expense of David Goffin and will face Felix Auger-Aliassime, who came from a set down to beat Dan Evans.

Matteo Berrettini remains in the hunt to win the Tennis Napoli Cup on home soil after a 6-2 6-3 quarter-final triumph over Taro Daniel.

Top seed Pablo Carreno Busta crashed out in Italy, losing 7-5 6-2 to Miomir Kecmanovic, who will face Lorenzo Musetti after he got the better of Daniel Elahi Galan. Mackenzie McDonald will come up against Berrettini after getting past Zhang Zhizhen.

Stefanos Tsitsipas sealed a Stockholm Open semi-final spot with a 7-5 6-3 win over Mikael Ymer and will take on Emil Ruusuvuori, who eliminated Frances Tiafoe.

Holger Rune and Alex de Minaur meet in the other last-four match in the Swedish capital following wins over Cameron Norrie and Denis Shapovalov respectively.

Grigor Dimitrov crashed out of the Stockholm Open to the unseeded Jiri Lehecka in a three-set thriller on Tuesday, as Botic van de Zandschulp also fell at the first hurdle at the European Open.

Dimitrov, seeded sixth in the Swedish capital, came up short against Lehecka, who seized a surprise 6-4 1-6 7-6 (7-5) win, his first on the ATP Tour since July.

Victory for Alex de Minaur was far more predictable, a 150th at tour level coming courtesy of a straight-sets defeat of Benjamin Bonzi.

In Antwerp, Dominic Stricker handed Van de Zandschulp a swift exit, winning 6-2 6-4 to stay on Lehecka's coat tails in pursuit of a place at the Next Gen ATP Finals.

Stricker's reward for this win will be a second-round encounter with French veteran Richard Gasquet, who knocked out three-time grand slam champion Stan Wawrinka on Monday.

At the Napoli Cup, fifth seed Miomir Kecmanovic saw off wildcard Flavio Cobolli with ease, but others found life rather tougher.

Respective seventh and eighth seeds Albert Ramos-Vinolas and Adrian Mannarino fell to Nuno Borges and Pedro Cachin.

Holger Rune maintained his impressive form by beating Thiago Monteiro in straight sets to reach the second round of the Stockholm Open on Monday.

Rune was beaten by Marc-Andrea Huesler in the final of the last tournament he entered in Sofia following a quarter-final appearance in Metz.

The Danish teenager, who last week announced Patrick Mouratoglou had joined his team for the rest of this season, defeated Monteiro 7-5 6-2 on his debut in the Swedish capital.

Rune did not face a break point and won 86 per cent of points on his first serve as he booked a meeting with Cristian Garin.

Garin beat qualifier Jason Kubler 6-2 6-4, while Maxime Cressy and Aslan Karatsev advanced to the last 16 at the expense of Ilya Ivashka and Lukas Rosol respectively.

Richard Gasquet consigned Stan Wawrinka to an early exit at the European Open, coming from a set down to win 2-6 7-6 (7-4) 6-4 in a battle of two of the most experienced players on the circuit.

Fifth seed Dan Evans beat Tallon Griekspoor 6-3 6-4 in the first round in Antwerp, while his fellow Brit Jack Draper was an emphatic 6-1 6-2 winner against Jenson Brooksby of the United States.

J.J. Wolf was no match for Felix Auger-Aliassime in the final of the Firenze Open, as the Canadian won 6-4 6-4 in Florence.

Auger-Aliassime is targeting a place in the end-of-season ATP Finals and took a huge step towards securing such a spot on Sunday.

The top-seeded 22-year-old only dropped one set throughout the tournament and has now won his second ATP Tour-level title.

His victory over Wolf, the world number 75 who will rise to 56 on Monday, took only one hour and 41 minutes.

"It never gets old. Winning, it always feels like the first time," Auger-Aliassime, the new world number 10, said in his on-court interview.

"It's so special to win, especially here. I had a fantastic week and it's been amazing.

"Every final is tough, it's the two best players of the week. Of course you try to win more than you lose the finals, and that's why I came out here today ready to give everything.

"We had some very tough rallies in the second set, feeling tough physically. But you keep pushing, try to keep the level high.

"But there's no magic. Sometimes you win, sometimes you lose, but of course I'm really happy because I came here [as] the first seed.

"I was the favourite in all of my matches on paper. It's never an easy position, so to come out and win my four matches with confidence and conviction, it's really good for my confidence."

Wolf saved nine of the 12 break points he offered yet could not make any inroads against Auger-Aliassime's serve, with the champion winning without conceding on his service game.

Andrey Rublev defeated Sebastian Korda in straight sets in Sunday's Gijon Open final to land his 12th ATP Tour title.

The Russian had already prevailed in Belgrade, Dubai and Marseille this year and added another crown to his collection with a 6-2 6-3 victory against Korda in 75 minutes.

Top seed Rublev had dropped only one set in his three matches en route to the final and impressed against Korda with 29 winners, three breaks and just four unforced errors.

Korda, seeking a second Tour-level trophy following success in Parma last year, had his serve broken in the fourth and eighth games of the opening set.

Some heavy-hitting exchanges kept spectators gripped, though Rublev proved too strong for Korda in the second set and earned the only break in the sixth game.

Rublev got over the line with his fourth match point and remains sixth in the chase for an ATP Finals spot, with four of those ahead of him already qualified, along with Novak Djokovic. 

Andrey Rublev set up a final meeting with Sebastian Korda at the Gijon Open, overcoming Dominic Thiem in straight sets in the last four.

The world number nine battled through an up-and-down opener before remaining patient to seal the second set and the match on Thiem's serve, taking a 6-4 6-4 victory.

Russian Rublev has now won eight successive sets of tennis against the 2020 US Open champion, and he is one win away from his fourth title of 2022 after triumphs in Belgrade, Dubai and Marseille.

Speaking on court after the win, Rublev said: "I was lucky I played a really good game and Dominic helped me out a little bit.

"Then I felt more confident and I was able to win in two sets, which was the most important thing. This week I have been playing really well, and I'll try to show my best tennis of the week tomorrow."

Korda will be Rublev's opponent on Sunday after the American saw off France's Arthur Rinderknech for a 7-6 (7-2) 6-3 win.

Meanwhile, at the Firenze Open, top seed Felix Auger-Aliassime saw off home favourite Lorenzo Musetti 6-2 6-3, moving one step closer to a second ATP Tour title.

The Canadian will face JJ Wolf in the final in Florence, after the American clinched a 6-4 6-4 win over Sweden's Mikael Ymer.
