Nine-time champion Novak Djokovic will make his return to the Australian Open against Spain's world number 75 Roberto Carballes Baena.

After being deported from Australia last year amid a row over his refusal of a COVID-19 vaccination, Djokovic is firmly back in favour and chasing history in Melbourne, with a record-equalling 22nd men's singles grand slam in his sights.

He begins against an opponent who in four previous main draw appearances has only ever won one singles match at Melbourne Park.

Defending champion Rafael Nadal, whose 22 slam titles Djokovic is seeking to match, has a tricky opener against rising British star Jack Draper, the world number 40.

Second seed Casper Ruud will tackle Czech Tomas Machac first up, with the 115th-ranked player unlikely to prove too daunting an obstacle for last season's French Open and US Open runner-up.

Fifth seed Andrey Rublev could face an awkward assignment against wildcard and former US Open winner Dominic Thiem, while Australia's Nick Kyrgios begins against Russian Roman Safiullin.

Neither 13th seed Matteo Berrettini nor five-time runner-up Andy Murray would have been delighted to be paired together, but that is what happened in Thursday's draw.

In the women's singles, top seed Iga Swiatek starts her bid for a first Australian Open title against Germany's Jule Niemeier, who caught the eye last year on a run to the Wimbledon quarter-finals.

American seventh seed Coco Gauff starts against Czech Katerina Siniakova, while Jessica Pegula, Gauff's third-seeded compatriot who recently beat Swiatek in the United Cup, will face Belgian Jaqueline Cristian.

Gauff could face former US Open winner Emma Raducanu in the second round. Unseeded Briton Raducanu starts against Germany's Tamara Korpatsch.

Former champions Sofia Kenin and Victoria Azarenka go head to head in the first round, with American Kenin unseeded this year and Belarusian Azarenka the 24th seed.

Azarenka's compatriot Aryna Sabalenka is fancied to do well, having banished last year's serving yips, and the fifth seed starts against Czech Tereza Martincova.

Tunisian second seed Ons Jabeur, runner-up at Wimbledon and the US Open, begins her latest quest for an elusive grand slam title against Slovenian world number 88 Tamara Zidansek.

Former US Open winner Bianca Andreescu is unseeded in Australia and Czech 25th seed Marie Bouzkova drew a possible short straw by getting the Canadian in round one.

Casper Ruud was given a wake-up call ahead of the Australian Open as he was beaten by Laslo Djere in Auckland.

Ruud, who was beaten by Carlos Alcaraz in the US Open final last year, was the top seed in New Zealand but came unstuck in the round of 16 on Wednesday.

Djere came from behind to defeat the Norwegian world number three 3-6 6-3 7-6 (7-3) and seal his place in the quarter-finals, where he will meet Constant Lestienne.

In the process, Djere recorded his first career victory over a top-five opponent.

Ruud must now shrug off the disappointment and switch his focus to Melbourne, where he will be hoping to break his grand slam duck.

David Goffin overcame qualifier Christopher Eubanks in straight sets to tee up a last-eight tie with Richard Gasquet, while Jenson Brooksby received a walkover due to Diego Schwartzman's injury.

Unlike Ruud, second seed Cameron Norrie did make it through. The world number 12, who spent the majority of his childhood in New Zealand, enjoyed a homecoming as he saw off Jiri Lehecka 6-4 6-7 (4-7) 6-3.

Norrie is unbeaten in 2023, having beat Alex De Minaur, Taylor Fritz and Rafael Nadal while in action for Great Britain at the United Cup.

"Obviously, there were [some] nerves in me, coming back to New Zealand I wanted to play well in front of everyone, and Jiri's a great player," said the 27-year-old.

"So, it wasn't easy, and credit to him in that second set for playing a really good tie-break. He really took it to me, but I really enjoyed the time on the court."

There was also a shock at the Adelaide International 2, where top seed Andrey Rublev succumbed to wildcard Thanasi Kokkinakis.

Rublev hit back after losing the first set but Kokkinakis ultimately prevailed 6-4 3-6 6-3.

Second seed Pablo Carreno Busta also fell out, losing to Kwon Soon-woo, leaving third seed Karen Khachanov as the favourite after his straight sets defeat of Marc-Andrea Huesler.

Mikael Ymer, Jack Draper, Miomir Kecmanovic, Alejandro Davidovich Fokina and Roberto Bautista Agut all progressed.

Gregoire Barrere withstood a barrage of aces from John Isner and a change of court triggered by Cyclone Hale as he upset the American sixth seed at the Auckland Open.

French qualifier Barrere and US veteran Isner were forced indoors by the adverse weather threat in New Zealand, with the entire Tuesday schedule taking place on inside courts and without spectators.

Despite Isner rifling down 28 aces to move 10 away from becoming the first man to post 14,000 in ATP tour and grand slam events, Barrere stuck with him and pulled off a 6-7 (3-7) 7-6 (7-5) 6-3 victory.

He snatched the only break of the match in game eight of the deciding set, before serving out for victory, with the world number 88 firing down 10 aces himself across the contest.

Argentine seventh seed Sebastian Baez also fell at the last-32 stage, bowing out 7-6 (7-1) 6-1 to American wildcard Ben Shelton.

Serbian Laslo Djere set up a second-round clash with top seed Casper Ruud by edging out Spain's Jaume Munar 3-6 6-1 7-6 (7-4), while Czech Jiri Lehecka will face second seed Cameron Norrie next after sinking Brazilian fellow qualifier Thiago Monteiro 6-3 7-5.

Ruud and Norrie received first-round byes.

At Adelaide International 2, American eighth seed Tommy Paul battled past Australian Christopher O'Connell 6-4 7-5, setting up an appetising second-round clash with Britain's Jack Draper, who won through on Monday.

There was a home success for the Australian crowd to cheer, though, as qualifier John Millman, who beat Roger Federer at the 2018 US Open, this time dug deep for a 4-6 6-3 7-6 (8-6) win against Spain's Albert Ramos-Vinolas.

Wins for Hubert Hurkacz and Magda Linette saw Poland advance to the City Finals of the United Cup in Australia on Tuesday.

Hurkacz made it through a tough encounter against Stan Wawrinka 7-6 (7-5) 6-4 to give Poland a 2-1 lead in their Group B tie with Switzerland in Brisbane, before Linette came from behind to beat Jil Teichmann 5-7 6-4 6-1 to clinch it.

Poland will face Italy in the Brisbane final, whose 5-0 whitewash of Norway included Matteo Berrettini sealing victory with a 6-4 6-4 win over Casper Ruud.

In Perth, Croatia advanced to the City Finals after a dramatic day that saw Caroline Garcia get France on the board with a straight sets win against Petra Martic, before Adrian Mannarino came from a set down against Borna Gojo to serve for the match as he looked to bring his country level at 2-2.

However, Gojo broke back in a tense encounter before winning a deciding tie-break to send Croatia through to face Greece, who sealed a 4-1 win against Belgium.

Stefanos Sakellaridis recovered from going a set behind to beat Zizou Bergs, before Maria Sakkari overcame Elise Mertens 6-1 7-5, with Sakkari and Stefanos Tsitsipas adding some gloss to the score with a mixed doubles success against Kirsten Flipkens and Michael Geerts. 

Spain and Australia were unable to progress but the hosts at least had the consolation of securing a victory thanks to wins for Jason Kubler against Albert Ramos-Vinolas, and the mixed doubles duo of John Peers and Sam Stosur against Jessica Bouzas Maneiro and David Vega Hernandez.

The USA had already secured their Finals berth against Great Britain in Sydney, but were ruthless as they finished off their tie against Germany to win 5-0.

After Jessica Pegula beat Laura Siegemund 6-3 6-2, Frances Tiafoe also defeated Oscar Otte in straight sets, before the American duo combined to beat Siegemund and Daniel Altmaier 6-7 (5-7) 6-4 10-7 to complete a clean sweep.

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.

Casper Ruud has been voted by his fellow ATP players as the winner of the Stefan Edberg Sportsmanship Award.

The 23-year-old enjoyed a fine season and sits third in the end-of-year rankings after winning three titles.

He also reached the final of the French Open, US Open and the ATP Finals, losing to Rafael Nadal, Carlos Alcaraz and Novak Djokovic respectively.

However, one title he does have is the Stefan Edberg Award, which according to the ATP's official website recognises "fair play, professionalism and integrity on and off the court".

Nadal and the now retired Roger Federer had won the award every year since 2004, with the Spaniard taking it five times – and the last four years running – and the Swiss on 13 occasions.

"A big thanks to everyone who voted for me for this year's ATP Stefan Edberg Sportsmanship Award," said Ruud.

"I feel very, very honoured and happy to win this prize this year. I will try to keep my mood in the right place for next year. Can't wait to be back on court."

Novak Djokovic ended his "roller coaster year" on a roaring high with victory at the ATP Finals, matching Roger Federer's record of six titles by sinking the hopes of Casper Ruud.

The Serbian said he had spent the season "on the needles", his colourful way of describing the nervousness and discomfort he had experienced during a campaign which saw him prevented from playing in Australia and North America.

Djokovic, who has refused to take a COVID-19 vaccination, has seen his career suffer because of that firm stance. He was thrown out of Australia in January, a humiliating way to begin the year.

Yet there is little doubting the 35-year-old remains the pre-eminent player on tour heading towards the 2023 season, even with the rise of Carlos Alcaraz, who ends the year as world number one.

A first ATP Finals triumph for Djokovic came in 2008, and he then won four in a row from 2012 to 2015, and now he has carried off the trophy once more, plus a cheque worth $4.74million, the biggest prize ever paid out in tennis.

"Seven years, it's been a long time. At the same time, the fact I've waited seven years makes this victory even sweeter and even bigger," Djokovic said.

Speaking on Amazon Prime, Djokovic said the win after all he has gone through felt "huge".

"I probably talked about this season and how unusual it is 1,000 times prior to this interview, so I'm not going to repeat what most people who follow tennis know," he said.

"[It's] just a big relief and satisfaction, and also I look forward to having a couple of weeks off, because I've been on the needles the entire year, whether for tournaments or waiting for permissions to go somewhere, so I'm really glad I managed to end it in a positive way."

He is the oldest champion in the tournament's 53-year history, breaking a record held by Federer, who was 30 when he won in 2011.

Djokovic said it was "really, really impressive" for Ruud to have reached grand slam finals in Paris and New York, and the ATP Finals title match, in a stellar year for the 23-year-old Norwegian.

But Djokovic was ruthless in Sunday's final, emerging a 7-5 6-3 winner thanks to a break of serve in each set, earning a fifth title of his disrupted year following wins at Wimbledon, Rome, Astana and Tel Aviv.

Thanking his team and supporters during the trophy presentation for "going through some tough times" with him, Djokovic said there were moments where he had needed "a shoulder to lean on, a shoulder to cry on".

The 21-time grand slam winner added: "It's been a roller coaster year really, something I've never experienced ever before in my life, and only we know what we've been through."

Novak Djokovic ended his tumultuous year on a breathtaking high by dismantling Casper Ruud to win the title match at the ATP Finals, pocketing almost $5million in the process.

The man who was deported from Australia after a vaccination and visa dispute in January, then refused entry to the United States later in the campaign, scorched to a 7-5 6-3 victory against rising star Ruud.

This was a sixth triumph for Djokovic at the ATP Finals, matching Roger Federer's record, and at the age of 35 he is also the oldest champion at the event. Federer was previously the oldest, being 30 when he captured the 2011 title in London.

The tournament has since moved to Turin, and Djokovic reels in $4.74million for a victory that shows he remains the player to beat, wherever and whenever he gets the chance to play.

Serbian superstar Djokovic had two chances to break in the second game but Ruud resisted, and the younger man saved another break point in the eighth game too, but a further opportunity came at 6-5 after Ruud paddled a backhand into the net. The 23-year-old Norwegian sent the ball long in the next rally to slip behind.

It was becoming a masterclass from Djokovic and he was pummelling the ball from the back of the court, breaking Ruud's serve for a 3-1 lead in the second set. Djokovic later won a 36-shot rally to set up championship point, sealing victory with an ace down the centre.

Ruud, a runner-up this season at the French Open and US Open, had watched each of Djokovic's previous ATP Finals victories on television, and this time he had a prime spot to witness the 21-time grand slam winner at the top of his game.

Try as he might, Ruud could not find a way to fight back once the stranglehold was with Djokovic, who heads towards 2023 with his appetite for the biggest trophies in tennis far from sated.

Casper Ruud swept through to a showdown with Novak Djokovic at the ATP Finals, making light work of Andrey Rublev to reach the trophy match.

The 23-year-old Norwegian has enjoyed a stunning season, reaching two grand slam finals, and his 6-2 6-4 semi-final dismissal of Russian Rublev was impressively authoritative.

After Ruud coasted through the opening set, the occasion fell wholly flat when Ruud broke serve in the first game of the second, and did so again in the third game.

Rublev sat shaking his head at his chair in the break between games, also shrugging his shoulders towards his support team and looking lost for ideas.

He only began to make an impact after slipping 4-0 behind, and at 5-2 he broke Ruud's serve to narrow the gap and give the Turin crowd hope the contest could take off.

At 5-4, it was briefly tense, but Ruud served for the match for a second time and this time made it count, sealing victory with a brilliant backhand winner to become the first Scandinavian finalist at the ATP Finals since Stefan Edberg in 1990.

Ruud will overtake Rafael Nadal and end the year at number two in the ATP rankings should he carry off the title on Sunday; however, he has a 0-3 career record against Djokovic. Djokovic earlier battled past Taylor Fritz by winning a pair of tight tie-breaks to earn a straight-sets victory in the first of Saturday's semi-finals.

Rafael Nadal wrapped up his ATP Finals campaign with a 7-5 7-5 victory over Casper Ruud on Thursday.

The Spanish great had already failed to make the last four after suffering defeat in his first two matches in Turin, but he finished his year in style courtesy of a hard-fought win over Ruud.

Nadal held firm when two break points down at 4-4, before breaking to love to take the opening set.

He sealed victory in the 12th game of the second set, powering a cross-court backhand winner to move 15-40 ahead and set the stage for a win that saw him end the year with a 39-8 tour-level record.

"I can't ask for more," Nadal said. "2022 has had a tough six months, two Grand Slams, and finishing the year in a high spot in the rankings. So, I can't complain at all. At my age, to be able to achieve and be competitive means a lot for me.

"For 2023, just let's try to have the right preparation, work the proper way and start the season with the right energy, the right attitude, to reach the level that I need to be competitive from the beginning. Let's try it, I am excited about it."

Ruud had already progressed to the semi-finals in Italy for a second consecutive year.

Casper Ruud secured his place in the last four of the ATP Finals and ensured Carlos Alcaraz will be the year-ending world number one by beating Taylor Fritz on Tuesday.

Ruud made it two wins out of two in the Green Group to seal his semi-final spot with a 6-3 4-6 7-6 (8-6) defeat of Fritz in Turin.

The third seed eliminated Rafael Nadal when he won the first set and in doing so guaranteed that injured 19-year-old Alcaraz will be the youngest player to be at the top of the ATP rankings at the end of a year.

Ruud stormed into a 3-0 lead and did not allow Fritz a way back into the first set, but the American broke for the first time to level the match when his opponent was serving to stay in the second.

The battling Fritz fended off two break points in the fifth game of the deciding set and saved two match points as he fought back from 5-1 down in the tie-break to draw level at 6-6.

Norwegian Ruud was not to be denied, though, becoming the first player to reach the semi-finals when eighth seed Fritz drilled a forehand long at the Palbata Alpitour.

Fritz will do battle with Felix Auger-Aliassime on Thursday for a place in the last four.

Casper Ruud opened his ATP Finals campaign with a 7-6 (7-4) 6-4 triumph over Felix Auger-Aliassime in Turin.

The victory put Ruud top of the Green Group, with the pool's two other players, Rafael Nadal and Taylor Fritz, set to face off later on Sunday.

A tight first set saw each game go to serve as it went all the way to a tie-break, with Ruud – this year's beaten US Open finalist – finding a crucial break at 3-2 up, giving him the momentum to nose ahead.

They continued to be closely matched in the second set too, though Ruud again managed to break Auger-Aliassime at a critical juncture in the match.

With the set tied at three apiece, ATP Finals debutant Auger-Aliassime double-faulted at 40-15 down on his own serve to put Ruud within two games of victory.

The world number four took full advantage, who is making his second appearance in the season-ending tournament, kicking on to secure a straight-sets success without offering a single break point to begin his tournament in impressive fashion.

In recent years, the notable absentee at the ATP Finals has been Roger Federer, with his last appearance in the tournament coming in 2019.

The lack of Federer at the showpiece event will be felt even more apparent this year after the Swiss maestro retired from tennis in September, though it is the absence of a player at the other end of his career that is more relevant in Turin.

World number one Carlos Alcaraz had to withdraw from the tournament after suffering an abdominal tear, which means his status at the top of the men's game is in jeopardy.

Rafael Nadal has spoken well of his 19-year-old compatriot in the past, but is not ready to pass the torch just yet, and could even topple Alcaraz from his number one spot.

The 22-time grand slam champion has finished as year-end number one five times previously, most recently in 2019. Should he accomplish the feat again this year it would put him in joint-second for most year-end finishes at the top of the ATP Rankings (since 1973) along with Pete Sampras (six).

In order to do so, Nadal will need to win the tournament, something he has never done before.

However, he comes into his 11th appearance in good form, and has won 32 per cent of his return games in 2022, the highest percentage by any player this year, and has converted 43.8 per cent of his break points in 2022, the third best amongst all players.

Stefanos Tsitsipas, meanwhile, is the other competitor who can knock Alcaraz off top spot, though his task to do so is a little more complicated as he needs to win every match on the way to the title in Turin. 

No player has played more matches in 2022 than Tsitsipas (80), 21 on clay, 11 on grass and 48 on hard courts; he has won 59 of them and lost 21.

Should neither man win at the Pala Alpitour, Alcaraz will breathe a sigh of relief and earn his first year-end number one finish, having taken his place after winning the US Open in September.

Nadal has been drawn into the Green Group with Casper Ruud, Felix Auger-Aliassime and Taylor Fritz, while Tsitsipas will be in the Red Group alongside Daniil Medvedev, Andrey Rublev and Novak Djokovic.

Djokovic can equal Federer record

One man surprisingly unable to end the year as number one is Djokovic, despite having done so on more occasions than anyone else in history (seven).

However, the 21-time grand slam champion can still make his mark in Italy.

Djokovic has had an up-and-down year, only playing in two of the four grand slams due to his vaccination status, though he was able to win Wimbledon for the seventh time, beating Nick Kyrgios in the final.

Should the Serbian go all the way and lift what would be his sixth ATP Finals title, he will go level with Federer for most victories since the tournament began in 1970.

Among the eight participating players in this year's tournament, Djokovic has won 87 per cent of his service games in 2022, the best percentage among these players and the sixth overall.

It would be quite the ending to the year for Djokovic, who finds himself in the unusual position of sitting eighth in the world rankings, and at the age of 35, who knows how many more appearances he will make at the event?

Strong field promises fireworks

As is the intent of the format, the ATP Finals should be a tightly-contested few days as the best men's players in the world come together.

Ruud will be looking to add to an already impressive season, having reached two grand slam finals and winning three tour-level titles, while Fritz is aiming to carry on the fine lineage of American players to have won the tournament.

Players from the United States have won the ATP finals 16 times, with Sampras and Ivan Lendl winning five of them each. It is the most by any country and 10 more than next best Switzerland (six, all Federer) and Germany (also six, three wins for Boris Becker, one for Michael Stich and two for last year's champion, Alexander Zverev).

Auger-Aliassime has had a strong end to the year, beating Djokovic at the Laver Cup before winning three titles in as many weeks in Florence, Antwerp and Basel.

Only John Isner (895) has recorded more aces in 2022 than Auger-Aliassime, who has registered 852 in total, averaging 10.9 per match.

"All the players who participate [at the ATP Finals], I have already faced them, I have beaten them," the Canadian recently said. "So for me, there's no reason why I can't show up to this tournament with the aim of winning it."

Medvedev was world number one as recently as September but enters this tournament in fifth, though he did win the Vienna ATP 500 event last month, while his first opponent in Turin, Rublev, enters with a 2022 record of 49-18, looking for his second straight 50-win season.

Whoever comes out on top at this year's ATP Finals, the race for supremacy in 2023 promises to be as delightfully chaotic.

Novak Djokovic remained on course for a record-extending seventh Paris Masters title after booking his quarter-final place with victory over Karen Khachanov.

The six-time champion avenged his defeat by Khachanov in the 2018 Championship match by running out a commanding 6-4 6-1 winner.

That gave Djokovic his 11th straight victory in the French capital, where he is unbeaten since that 2018 defeat, while he has also won each of his last 11 Tour-level matches.

The Serbian, who has triumphed in Tel Aviv and Astana during that streak, set up a last-eight clash with Lorenzo Musetti after the Italian came from behind to stun third seed Casper Ruud 4-6 6-4 6-4.

The Naples champion recorded his maiden top-five victory at the seventh attempt, while he hit 37 winners to advance to his first ATP Masters 1000 quarter-final.

Meanwhile, world number one Carlos Alcaraz won five out of seven break points as he breezed past Grigor Dimitrov 6-1 6-3 to reach the last eight in Paris for the first time.

There, he will play Holger Rune after the Stockholm champion defeated seventh seed Andrey Rublev in straight sets.

Fifth seed Stefanos Tsitsipas overcame Corentin Moutet 6-3 7-6 (7-3) to reach his 14th quarter-final of the season, where he will face Tommy Paul after the American denied Pablo Carreno Busta 6-4 6-4.

Felix Auger-Aliassime was a commanding 6-1 6-3 victor over Gilles Simon. The eighth seed will take on Frances Tiafoe, who defeated Alex De Minaur 6-3 7-6 (7-5).

Novak Djokovic and Casper Ruud were made to work hard for victory in their opening matches at the Paris Masters on Tuesday.

For Djokovic, a 10th win in a row came in an absorbing battle with his Paris-born American opponent Maxime Cressy, who displayed a typically aggressive approach on serve, with 15 aces and 10 double faults overall.

Djokovic was strong on his own delivery, however, with the Serbian losing just six points on serve and not facing a break point on his way to a 7-6 (7-1) 6-4 victory.

"I'm happy with the way I played," Djokovic said. "When chances were presented, I was able to use them, even though I did have some missed break points.

"But it was very challenging, first match with a guy who serves extremely well and strong and fast.

"He's comfortable coming to the net. It's nice to see. I think he's the only guy that really comes to the net after every first and second serve. I think it's good for tennis to see that, particularly in these modern times when most of the players are playing from back of the court. He's a very athletic guy.

"It's difficult to play him definitely in these kind of conditions where balls are flying through the court and it's quicker than it was last year. So tough to break.

"But I didn't make too many unforced errors. I'm very pleased with the way I served, with the way I was holding my service games. Just the way I felt, the way I played, it was all positive."

Third seed Ruud ground out a 6-1 7-6 (9-7) victory against Frenchman Richard Gasquet, with the Norwegian saving three of four break points in what proved to be a tightly fought contest.

Mistakes from Gasquet were ultimately costly, the veteran having 10 unforced errors in the second set compared to Ruud's two.

Seventh seed Andrey Rublev was also victorious, the Russian winning 6-2 6-3 against American John Isner, while the British duo of Jack Draper and Dan Evans progressed to the last-32 stage, beating Arthur Rinderknech and Brandon Nakashima respectively.
