Daniil Medvedev is convinced Novak Djokovic will be glued to Sunday's Australian Open final, as the men's grand slam record goes on the line once more.

It was Medvedev who denied Djokovic a 21st singles major in the US Open final in September, inflicting a straight-sets defeat on the Serbian who was chasing a sweep of the 2021 grand slams.

Now Medvedev stands in the way of another of the 'Big Three', with Rafael Nadal also chasing a 21st slam and the outright lead on the all-time list.

Djokovic, Nadal and Federer each have 20 grand slam singles titles, and it remains to be seen whether any of that trio triumph again on the big stage, with Medvedev confirming himself as a leader of the upcoming generation.

The deportation of Djokovic from Australia before this tournament caused a major stir, denying the nine-time champion at Melbourne Park a run at history.

And all Djokovic can do is sit and watch from a distance, perhaps hoping for a Medvedev victory.

"I guess last time Rafa was watching near the TV, I don't know who he was cheering for," Medvedev said, harking back to the US Open. "But I think Novak will be watching this one in two days also."

The mention of Djokovic in Medvedev's on-court interview led to rumblings in the crowd, with many Australians having been glad to see him removed from the country when his visa was revoked.

When Djokovic was again mentioned in a follow-up interview with Eurosport, Medvedev said: "I'm definitely not going to think about this before or during the match. After the match, depending on the result, I'm going to think about him a little bit and about Roger probably also."

Medvedev's first taste of a grand slam final was against Nadal at the 2019 US Open, when the Russian lost a five-set thriller.

"We've played a few matches since then, and I'm ready," Medvedev said. "I know Rafa is a very strong player and I will need to show my best to try to win this match."

Medvedev, runner-up to Djokovic in Melbourne last year, aimed an outburst of anger towards umpire Jaume Campistol during the second set of his four-set victory over Stefanos Tsitsipas on Friday.

He was furious at Tsitsipas seemingly being coached by the Greek star's father from the players' box, but Medvedev quickly realised his own behaviour was unhelpful.

"I don't think emotions, bad emotions, help me too much and when I made it, many times I lose the match because of this," he said. "As soon as I did it, I was like, 'That was a big mistake'.

"But I'm happy I managed to re-concentrate for the beginning of the third set."

Having lost the second set, Medvedev snatched a crucial break at the end of the third, before cruising through the fourth to seal a 7-6 (7-5) 4-6 6-4 6-1 victory.

Medvedev said he had felt "so dead" after beating Felix Auger-Aliassime in a near five-hour marathon in the quarter-finals, but his energy has been replenished.

"I'm happy today was not five hours, so I could recover faster for the next one," he said.

"I'm gonna play against one of the greatest, and what's funny is again I'm going to play someone going for the 21st slam."

Before the tussle with Nadal, Melbourne will be gripped by Ash Barty's own pursuit of history, bidding to become the first Australian since Chris O'Neil at the 1978 tournament to land the women's singles title.

Barty faces Danielle Collins on Saturday, and Medvedev, as is his wont, managed to rile some of Friday's crowd by being non-committal on whether he would watch Barty, whose title match begins at 19:30 local time (08:30 GMT).

"I'm usually going to dinner at 8.15pm," Medvedev said.

Urged by on-court interviewer Jim Courier to come up with a different answer, Medvedev added: "I'm going to watch it on my phone guys, I'm going to watch it."

Daniil Medvedev roared into a second consecutive Australian Open final as he downed Stefanos Tsitsipas in a fiery last-four showdown.

The Russian, who came from two sets down to see off Felix Auger-Aliassime in the last round, triumphed 7-6 (7-5) 4-6 6-4 6-1 to set up a final with Rafael Nadal.

The US Open champion improved his head-to-head record with Tsitsipas to 7-2 in a contest where tempers frayed, mostly on Medvedev's side of the net.

He accused Tsitsipas' father of coaching from the sidelines and received a warning for his persistent complaining, but the second seed also managed to channel his aggression into a stellar performance.

The first set went the distance after Tsitsipas, who employed a bold approach in taking the match to Medvedev, fended off three break points when serving at 4-4.

Medvedev was 4-2 down in the tie-break but dug deep to claim it, underlining his mental toughness when backed into a corner.

Tsitsipas maintained his positive attitude and broke in the opening game of the second set, only to surrender that advantage in a sloppy sixth game as his accuracy abandoned him.

It was Medvedev who lost his way at 4-4, though, two double faults and a terribly skewed forehand seeing him lose serve, with Tsitsipas capitalising to seal the set.

Medvedev lost his cool with the umpire, bemoaning supposed coaching from Tsitsipas' father, but it only seemed to fuel him.

With Tsitsipas serving to stay in the set, Medvedev showed his range with a drop-shot winner and double-handed forehand bullet en route to a timely break to reclaim the lead.

And he was at his imperious best in the fourth, producing an array of stunning passing shots as Tsitsipas simply ran out of answers.

Medvedev now has the chance to go one better than last year, when he lost in the final to Novak Djokovic.

DATA SLAM: Medvedev clinical behind first serve

Medvedev had to put a gruelling five-set quarter-final clash behind him on Rod Laver Arena and it did appear to take him some time to find his groove.

But he applied huge pressure with his consistency on his first serve, winning 91 per cent of those points.

Rodrigo De Paul claims Argentina were subjected to some rough off-field treatment from hosts Chile before their World Cup qualifier.

The midfielder said the Albiceleste were prevented from using the bathroom on arrival, had no air conditioning or water and were made to suffer the sound of sirens during their stay in Calama. 

It did not appear to derail the visitors, already safely through to Qatar 2022, as they secured a 2-1 win despite the COVID-enforced absences of Lionel Messi and coach Lionel Scaloni.

"They didn't even let us go to the bathroom when we got off the plane," De Paul told reporters. "They cut off our air conditioners, we had no water and they made sirens sound throughout the stay.

"I'm not saying it's right or wrong, but, as an Argentine, every team that comes to my country, we have to make them feel as comfortable as possible and we have to win on the playing field where it belongs."

Angel Di Maria and Lautaro Martinez netted first-half goals around Ben Brereton-Diaz's looping header as Argentina extended their unbeaten run to 27 games.

The victory improves second-placed Argentina's CONMEBOL World Cup qualifying campaign to 32 points from 14 games, while Chile are battling to reach Qatar 2022.

After a solid if unspectacular showing, assistant coach Walter Samuel was pleased to see how well the team coped despite being without talisman Messi.

"Sure there are things to improve, but the team showed character in a difficult environment," he said.

"Messi is the leader of this team, but we were able to do very well without him. We lacked other guys because of Covid that we wanted to be there, but the team made a great effort and I want to thank them for that.

"The character of the boys is moving. All the players start from scratch and want to earn a place in the World Cup. There is healthy competition here."

Andrew Wiggins thought he was dreaming when he learned he had been selected to his first NBA All-Star Game as a starter for the Western Conference team.

Wiggins and Ja Morant earned their first call-ups when the starters were confirmed on Thursday, with LeBron James and Kevin Durant named as captains.

While Memphis Grizzlies guard Morant was widely expected to be picked, fellow first-time starter Wiggins was seen as a surprise selection by some.

It was clear how much the achievement meant to the Warriors forward as he spoke to reporters after the 124-115 win over his former team, the Minnesota Timberwolves, on Thursday.

Wiggins will join Warriors teammate Stephen Curry in representing the West when the annual midseason exhibition is held on February 20 in Cleveland.

"It was mind-blowing," Wiggins said about learning the news. 

"I was taking my pregame nap. My girl woke me up and said, 'You're a starter! You’re a starter!' – I thought I was dreaming for a second!

"It means a lot. I've been working hard in different situations and I found a home here, something that works. Hopefully I can keep it going and this is not the last one.

"There has been nothing but love [from my teammates]. As soon as I got here, in the game, this whole time, I'm sure when I go down the locker room, they will give me more love. So, it's a special feeling."

Wiggins had 19 points that included five three-pointers as the Warriors improved to 36-13 for the season and 23-4 at home by beating the Timberwolves.

They sit second in the Western Conference and Wiggins is their second-highest scorer this season with 18.1 points per game, only behind Curry (25.8).

Steve Kerr was delighted for his player, who has had to wait eight seasons for his first selection.

"One of the proudest moments just to see what Wiggs has done since he got here a couple of years go," said the Warriors coach.

"The journey he has travelled has been rocky at times, and to see how hard he's worked and to see all the work rewarded, just could not be happier for him.''

Curry had a team-high 29 points for the Warriors against Minnesota.

They have a huge game next at home to the Brooklyn Nets (26-19) on Saturday.

Just months ago, there were doubts over Rafael Nadal's future. Now, he is a win away from a record-breaking major triumph.

Nadal overcame Matteo Berrettini 6-3 6-2 3-6 6-3 in the Australian Open semi-finals on Friday, reaching his 29th grand slam decider.

The Spaniard is a win away from a 21st grand slam title, which would break his tie with Roger Federer and Novak Djokovic for the most won by a man.

Such events looked incredibly unlikely just months ago.

Nadal ended his 2021 season in August after playing just seven events, a persistent foot injury not only derailing his season but threatening his career.

"Everybody around me, me included, of course, but everybody around me had a lot of doubts. Not about the Australian Open, no, but about coming back on the Tour because the foot was bothering me a lot of days," Nadal said after his third-round win over Karen Khachanov.

"Of course, still today there are doubts because the foot, as I said the other day, is an injury we cannot fix … so we need to find a way that the pain is under control to play, to keep playing. That's the goal.

"Honestly, I was not able to practice very often. But when I was practising, the feeling on the ball was quite good. There have been a lot of months without competing. The movements, all this stuff, you need to recover day by day. There is no way to recover those things without competing. That's what I need, keep playing. Already three and three, so six matches on my back, and positive ones. Every day a little bit better, so I'm happy for that."

After a four-month absence, Nadal made his return at an exhibition in Abu Dhabi in December. Days later, he tested positive for COVID-19.

Still, he made the trip to Australia, winning his 89th ATP Tour title at the Melbourne Summer Set, his first hard-court crown since February 2020.

That success was incredible, given Nadal played just 14 tournaments in total in 2020 and 2021.

"Of course, when you are getting a little bit older, all the comebacks are tougher," Nadal said after beating Marcos Giron in the opening round. "This has been especially, well, difficult because it's not only a comeback from an injury, it's a comeback trying to be back on the Tour after almost two years playing not many events with the virus.

"If you remember in 2020 I only played here and Acapulco, then I just played in Rome, Roland Garros, Paris and London. Six events.

"In 2021 I played just here and then [it] was clay, Monte Carlo, Barcelona, Madrid, Rome, Roland Garros. Washington, yeah. Another six events – 12 events in two years are not many. If we add that I was not able to practice very often, too, it's a really tough one, no?

"But here I am. I am super happy about all the work that we have done to try to be back. We are here enjoying the tennis, and that's it. We're going to keep trying hard."

Nadal is back. Not just back playing, but back fighting his way into grand slam finals, and back in position to make more history.

Klay Thompson warned that a full-strength Golden State Warriors are "going to be real scary" after he marked his return to form and fitness with a fine display on Thursday.

Thompson and Stephen Curry combined for 11 three-pointers as the Warriors strung together a fourth consecutive win with a 124-115 triumph over the Minnesota Timberwolves.

With 23 points, five rebounds and four assists to his name, it was a showing that suggested Thompson's injury woes were well behind him, with a combination of ACL and Achilles problems having sidelined him for two and a half years before his return earlier this month.

And with Andre Iguodala and Draymond Green among the players still waiting to come back into the side amid injury lay-offs, Thompson is excited to see what the Warriors can do when they have everyone available.

"I thought we were going to play like this my first game back. Maybe I was a little naive," he said.

"It's going to get better every night. And when our full squad is back, it's going to be real scary."

Curry finished with 29 points – including six triples – eight rebounds and six assists as the Warriors rallied from a three-point half-time deficit with a 38-20 third quarter to improve to 36-13, with the best home record (23-4) in the NBA.

Former Rookie of the Year Andrew Wiggins, on the same night he was named an All-Star for the first time, contributed 19 points, five rebounds and four assists.

Karl-Anthony Towns had 31 points, 12 rebounds and six assists and Anthony Edwards added 27 points with six rebounds and six assists.

Coach Steve Kerr took huge encouragement from a performance that hinted at what might be to come from his side in the remainder of the season.

"It's a really good indicator of what our team can look like with Klay back and everybody healthy, for the most part, in terms of our shooters," he said.

"With these last couple of games, the spacing that we've had and the ball movement, we've gotten great shots."

Curry, whose three-point shooting had come in for scrutiny after a notable drop-off, was pleased to see his self-belief pay off as he put on a show.

"Stay confident, keep taking shots I feel like I can make," Curry said of his approach in the wake of the criticism that had come his way.

"It's the balance of maintaining who I am on the court and how I enjoy the game even when things aren't going my way. That joy has to remain. Everybody feeds off of it. If I'm in my feelings and thinking about my shot, it takes away from everything else that we do.

"When a couple goes down early, it's a good feeling. You want to ride that energy, that wave."

Rafael Nadal insisted his run to the Australian Open final was "completely unexpected" after moving to within a win of a record-breaking grand slam title.

Nadal, 35, overcame Matteo Berrettini 6-3 6-2 3-6 6-3 in their semi-final under the Rod Laver Arena roof on Friday.

After doubts over his career due to a persistent foot injury, Nadal is into a 29th grand slam final and a win away from a 21st major crown, which would break a tie with Roger Federer and Novak Djokovic for the most won by a man.

The Spaniard said he had no expectations to reach the decider in Melbourne, where Daniil Medvedev or Stefanos Tsitsipas await.

"For me it's something completely unexpected, so I am super happy. Of course everybody knows me, and I'm always going to try my best. Of course my goal now is to win," Nadal told a news conference.

"As I said, for me, it's a present, just be here and play tennis. I am taking now things a little bit in a different way, of course always with competitive spirit that I have, because I can't go against that. It's my personal DNA.

"But in some way, I don't know, just be what I am and be able to have the chance to compete at this level, it's a positive energy for me to keep going, because at the end of the day, and being very honest, for me it's much more important to have the chance to play tennis than win the 21. Because that makes me more happy in terms of general life to be able to do the thing that I like to do more than achieving another grand slam.

"At the end of the day, life, it's about happiness and what makes me happy. It's about just having the chance to do what I like to do."

Nadal ended his 2021 season in August and, after a four-month absence, returned for an exhibition event in Abu Dhabi last month.

He claimed his 89th ATP Tour title in Melbourne earlier this month before progressing to the Australian Open final.

"I feel alive in terms of my tennis life, you know, in terms of my tennis career," Nadal said.

"In my personal life, I honestly have a good life. I feel lucky that my family is healthy, and during these challenging times that's everything. More important than tennis, for sure. 100 per cent.

"But, yeah, I explained before, for a long time I wasn't able to practice. Sometimes I went on court and I was able to practice 20 minutes, sometimes 45, sometimes zero, sometimes two hours, but have been very, very rough in terms of imagining myself playing at the best-of-five at this moment.

"So, yeah, I don't know. Super happy. It's true that I worked hard for a long time every single day in terms of when I was not able to play tennis I was working hard in the gym.

"I think I'm never going to say I deserve, because a lot of people deserve. But I worked the proper way, and I hold the positive spirit and attitude to have the chance to give myself a chance to be back."

Ash Barty's form at the Australian Open gives her deserved favourite status for the final, but in Danielle Collins one of the most dangerous players on the WTA Tour stands between her and history.

Barty has ruthlessly cruised into Saturday's final – the first Australian to reach the women's singles decider in 42 years – in brilliant form.

The two-time grand slam champion has lost just 21 games on her way to the showpiece, dropping serve just once.

Barty, the world number one, has appeared a class above at the year's first grand slam, where she is bidding to become the first Australian singles champion since Chris O'Neil in 1978. But she faces a huge test in the final against American 27th seed Collins, who is into her first major decider.

After three straight losses to Barty, two of which were on clay, Collins beat the Australian in straight sets in Adelaide last year in a sign of what she is capable of. Collins, who came from a break down in both sets in that win, possesses the power to threaten Barty on Rod Laver Arena.

Barty's variety – her serve, backhand slice and ability to construct points – has been much talked about in Melbourne this year.

Her 35 aces for the tournament are the second most, and exactly half of her first serves have been unreturned at the event, the highest percentage of any player in the women's draw. While Barty will try to unsettle Collins with her variety, the American is likely to respond with power. Collins has crushed 32 return winners at the event, a tally that is eight more than the next best.

Collins has also delivered 164 winners to 149 unforced errors, showcasing her aggressiveness, while Barty is at 106 and 96 respectively.

If Barty can extend the points, she will fancy her chances of a first Australian Open title. Collins has spent 10 hours, 37 minutes on court compared to Barty's 6:06, but shorter points would also suit the 2019 Australian Open semi-finalist.

Of points between zero and eight shots this tournament, Collins has won 458 of 809 (56.6 per cent), while Barty is 331-202 (62.1). But of rallies of nine-plus shots, Collins is 23-31 compared to Barty's 30-19 at the 2022 event.

Barty will be well aware of what Collins is capable of, but should have confidence her best is more than good enough to end Australia's long wait.

Los Angeles Lakers' All-Star Anthony Davis underwent an X-ray on a troublesome wrist but insists there is nothing structurally wrong with it.

Davis had a first-quarter scare in Thursday's 105-87 loss to the Philadelphia 76ers when he landed on the wrist in his second game back after an MCL sprain kept him out for 17 games.

The 28-year-old power forward seemed troubled by the wrist complaint at times, yet still scored a game-high 31 points along with 12 rebounds and four blocks in an entertaining battle with Joel Embiid.

Davis left the court and had the wrist re-taped before playing on, confirming he had undergone an X-ray which was clear when asked.

"On a play on a back cut, I dunked it and Joel tried to block it," Davis said at the post-game news conference. "Body contact, went to the ground and tried to catch myself and landed on my wrist.

"[I'm] a little sore. Nothing wrong with it. No fracture or nothing. Just a soft tissue injury, soreness and stiffness."

Davis added: “My wrist was bothering me toward the end so I was trying to shoot the ball. [To] follow through and stuff and see if I could shoot, to be honest."

The game may have been Davis' second game back but it was not alongside All-Star teammate LeBron James who was absent with knee soreness.

The pair have struggled to regularly play together, much to the frustration of Davis who admitted he did not know James was out until shortly prior to tip-off.

"I found out when I literally got to the arena when I was changing to go on to court," Davis said.

"Someone said 'you know Bron's not playing?', 'I didn’t know that'. It's been a thing all year. Even last year, we were flopping in and out of the line-up."

Lakers head coach Frank Vogel said James would be "day-to-day" with the knee soreness, with a game against the Charlotte Hornets to come on Saturday.

"He's a big part of what we're trying to do," Davis added. "He was playing out of his mind. I don't know his status for tomorrow but we've got to be able to win ball games until he gets back."

Rafael Nadal is a win away from a record-breaking 21st grand slam title after getting past Matteo Berrettini to reach the Australian Open final on Friday.

Nadal overcame the Italian seventh seed 6-3 6-2 3-6 6-3 after two hours, 55 minutes under the Rod Laver Arena roof in their semi-final on a stormy day in Melbourne.

The Spanish star will face either Daniil Medvedev or Stefanos Tsitsipas in the decider, in which he can break the record for most grand slam titles won by a man.

Nadal had won his only previous meeting with Berrettini and he targeted the Italian's backhand from the outset, and it worked wonders.

Berrettini, however, fought hard and forced a fourth set against Nadal, who reached his sixth Australian Open final and 29th major decider, a tally only bettered by Roger Federer and Novak Djokovic (31 each).

Nadal targeted the Berrettini backhand from the start, and it helped yield a break in the second game.

Back-to-back unforced errors from that wing, the second pulled wide, from Berrettini handed Nadal a 2-0 lead.

That break proved to be enough for Nadal in a 43-minute opening set, closed out despite Berrettini briefly threatening in the ninth game.

Perhaps still recovering from the disappointment of the first set, Berrettini was broken to start the second, three unforced errors – two from a forehand side that had appeared capable of doing damage to Nadal – giving the Spaniard a break point he converted with a forehand winner.

Berrettini had no answers to Nadal's consistency and relentlessness and even his forehand was beginning to let him down as he fell 3-0 behind in the second set, a deficit he was never going to recover from.

Nadal was unable to pull away early in the third set and instead it was Berrettini, suddenly sparked to life and looking far more energetic, who struck to break for 5-3.

A running forehand pass down the line helped set up the break chance and Berrettini delivered a forehand winner before serving it out to love.

Berrettini went on a run of winning 23 consecutive points on serve, but when that was ended in the eighth game of the fourth set, he found trouble.

He saved a break point after a 23-shot rally but then netted consecutive forehands to fall 5-3 behind, Nadal closing out his victory to reach the final.

DATA SLAM: Nadal showing no signs of slowing down

Even at 35, Nadal has reached yet another grand slam final.

He became the fifth man aged 35 or older to reach a grand slam final in the Open Era, after Federer, Ken Rosewall, Mal Anderson and Andre Agassi.

The win over Berrettini also saw Nadal beat a top-10 player at the Australian Open for the first time since 2017.

Berrettini – 38/39

Joel Embiid scored 26 points as the Philadelphia 76ers continued their hot form with a 105-87 win over the Los Angeles Lakers without LeBron James on Thursday.

James missed the game with left knee soreness but Anthony Davis, in his second game back after an MCL sprain, scored a game-high 31 points with 12 rebounds in his absence.

But the 76ers were too good, clinching their 13th win from their past 16 games, to improve to 29-19 and fifth in the Eastern Conference.

Embiid, matched up on Davis, was not at his best but still had 26 points with nine rebounds and seven assists. The 76ers center's haul marked 16 straight games with 25 or more points.

Tobias Harris scored 23 points for Philadelphia who were always in control, while second-season guard Tyrese Maxey contributed 14 points, seven rebounds and 10 assists.

Curry and Klay lead Warriors second-half rally

Stephen Curry and Klay Thompson combined for 11 three-pointers as the Golden State Warriors clinched their fourth straight win, triumphing 124-115 over the Minnesota Timberwolves.

Curry finished with 29 points including six triples, eight rebounds and six assists, while Thompson added 23 points, five rebounds and four assists as the Warriors rallied from a three-point half-time deficit with a 38-20 third quarter to improve to 36-13, with the best home record (23-4) in the NBA.

Former Rookie of the Year Andrew Wiggins, on the same night he was named an All-Star for the first time, contributed 19 points, five rebounds and four assists.

Karl-Anthony Towns had 31 points, 12 rebounds and six assists and Anthony Edwards added 27 points with six rebounds and six assists.

Brazil head coach Tite has criticized the decision to appoint a Colombian referee for Thursday's chaotic 1-1 World Cup qualifying draw with Ecuador.

Colombian referee Wilmar Roldan handed out four red cards throughout the game, including two to Brazilian goalkeeper Alisson which were both rescinded by the VAR, along with two overturned penalty awards for Ecuador.

Trailing 1-0 to Casemiro's first-half strike, Ecuador had a 55th-minute penalty awarded by Roldan overturned when it was determined Pervis Estupinan had dived in the box as opposed to being fouled by Raphinha.

In stoppage-time, the hosts again thought they had a penalty which could have led to the winner after a foul from Alisson but the award was overturned by the VAR, offering the Liverpool goalkeeper and Brazil a late reprieve.

Tite was critical of Roldan's "impulsiveness" but also the decision to appoint a referee from Colombia, who came into this matchday fourth in CONMEBOL World Cup qualifying behind Ecuador.

“Today there was no point in appointing a referee from the fourth country in the table, when the third and first were playing," Tite said at the post-game news conference.

"Roldan is a good referee, but it gives for interpretations. The designation took a bit of sensitivity."

Tite added: "It was a difficult game. The number of fouls was exaggerated, 20 fouls by Ecuador and 12 by us.

"The circumstances happened, it wasn't evil, it was impulsive. Incorrect, yes. And it needs to be corrected, yes. It needs to be mature, yes. But it wasn't evil."
