Stephen Curry scored 46 points including eight three-pointers as the Golden State Warriors defeated the Memphis Grizzlies 113-104 on Thursday.

Curry fell four points shy of his season-high 50-point haul but dominated throughout for the Warriors, shooting eight-of-14 from beyond the arc with four rebounds and four assists. The two-time MVP brought up his third return of 45 points or more this season.

Gary Payton II played a key role in the starting rotation with 22 points with four triples including a clutch three-pointer in the fourth quarter.

Curry's haul marked a return to form as Golden State improved to 26-6, remain one-half game behind the Phoenix Suns (26-5) for the best record in the NBA ahead of their Christmas Day match-up.

LeBron, Kemba and Jokic heroics fall short

LeBron James scored 36 points with nine rebounds, six assists and two blocks but it was not enough to prevent the Los Angeles Lakers from going down 138-110 to the San Antonio Spurs. The result leaves the Lakers with a record below .500 at 16-17 after four straight defeats.

Kemba Walker produced a vintage display with a season-high 44 points with nine rebounds and eight assists as the New York Knicks went down 124-117 to the Washington Wizards.

Reigning MVP Nikola Jokic's heroics were also in vain as the Denver Nuggets lost 115-107 to the Charlotte Hornets despite the Serbian's 29 points, 21 rebounds and five assists.

Devin Booker (30 points, seven rebounds, seven assists) and Deandre Ayton (19 points, 12 rebounds) led the way as the Suns stayed top and claimed their fifth straight win in a 113-101 triumph over the Oklahoma City Thunder, while Khris Middleton (26 points, five rebounds, seven assists) and Jrue Holiday (24 points, seven rebounds, seven assists) delivered again in Giannis Antetokounmpo's absence as the Milwaukee Bucks beat the Dallas Mavericks 102-95.

Embiid loses his radar

Joel Embiid shot six-of-17 from the field as the Philadelphia 76ers lost 98-96 to the depleted Atlanta Hawks. Embiid finished with 23 points, 10 rebounds and two assists.

Alexander Zverev believes he will form a big three with Novak Djokovic and Daniil Medvedev in 2022 but hopes he will not get the chance to become world number one at the Australian Open.

The German is knocking on the door near the top of the rankings after a fine year that saw him win six titles, including the season-ending ATP Finals in Turin and an Olympic gold medal in Tokyo.

Zverev, currently ranked third, could go top of the rankings if he wins the Australian Open, which starts next month, but that is only possible if current world number one Djokovic does not play.

And Zverev is hopeful the Serbian will take part despite continued uncertainty over his participation in the tournament amid intense debate over his COVID-19 vaccine stance.

Djokovic, a nine-time Australian Open winner, is yet to disclose his vaccination status.

Tournament chief Craig Tiley said this week he is still hoping to see the tour's top player participate if he meets the required conditions, which are either being vaccinated or having a medical exemption.

"The situation with Novak and Australia is still a big question mark," Zverev said in a podcast appearance with Eurosport Germany. 

"Of course, I hope that he will be allowed to play, that is very clear.

"There are thousands of mathematical calculations, if he doesn't play Australia and I win the Australian Open, then I'm number one in the world and so on and so forth.

"At the end of the day, now is not the time to think about [being world number one]. Now is the time to prepare as best as you can so you're physically able to play for it."

As well as his silverware, Zverev made the last four of the French Open and US Open, and the 24-year-old believes his experience has begun to come to the fore.

Zverev had a 59-15 record this season and recorded at least one victory against every other player inside the top 10 of the ATP year-end rankings.

"I've become much calmer and I'm also getting older," he added.

"I'm not 18 or 19 anymore. I understand maybe a bit more things about life and understand that you just have to keep calm in important situations. That has had its effect on me this year.

"I think next year could be very similar to the last six months from this year.

"Before, there used to be always talk about Rafael Nadal, Roger Federer and Novak Djokovic – now the big titles were the Olympics, US Open, Turin and Wimbledon, and they were all won by Medvedev, Djokovic and me. 

"I don't expect it to be any different next year."

Joe Root has backed himself to score a maiden Test century in Australia as England search for a response in the Ashes after a dismal start.

England have been comfortably dispatched by Australia in the opening two Tests, succumbing to a 275-run defeat in Adelaide after a nine-wicket beating in Brisbane.

The tourists are without a win in 12 Test matches in Australia – their joint-longest such run (also 12 between January 1937 to February 1951) – and must defeat Justin Langer's side in Melbourne to stop them from retaining the urn.

Root has been in fine form, scoring 175 runs at an average of 43.75, but the England captain has yet to convert to three figures despite registering eight half-centuries in Australia - only Bruce Laird (nine times) has reached fifty more times in Tests Down Under without ever managing to a ton.

Indeed, Root has already surpassed Michael Vaughan (1,481 in 2002) for the most Test runs in a calendar year by an England player and sits fourth on the all-time list with 1,630 runs in 2021.

Root will eye the Boxing Day Test as a chance to further his record haul and the 30-year-old remains confident he can manage a maiden ton on Australian soil sooner rather than later.

"I expect a response from our players and I would like to bring a nice Christmas present home for everyone who stays up," Root told reporters.

"I feel in a really good place with my batting. I feel confident I can, in these next three games, bang out a hundred in these conditions.

"I know that's a brave thing to say but my conversion rate, this year, it's not been an issue at all.

"I feel like I have managed that well and have an understanding of how I want to score my runs. There's clarity there, I just need to keep putting myself in those positions, just have the bit between my teeth, [make it] 'over my dead body'".

Australia number three Marnus Labuschagne, who leads the Ashes scoring charts with 228 runs, overtook Root as the ICC's top-ranked men's Test batter and England's skipper admitted he wants his title back.

"I've never been one for that but it would be nice to have it back for Christmas," he responded when asked about being displaced at the top of the rankings.

Root will also be expecting a response from his bowling attack after he provided a scathing summary post-match in the second Test, in which he slammed his bowlers for repeating mistakes from four years ago and needing to be braver with their lengths.

He hopes his outburst, which was followed up by a "brutally honest" Chris Silverwood debrief with the England players, will act as a catalyst for change on Saturday.

"I did [get angry] at the end of the last game because of the situation we're in and the manner in which we lost," he continued.

"I'll always try to look at things with a level, pragmatic approach but I don't think you could after the way we've played those last two games. I expect a response from everyone this week.

"Twice now we've got ourselves into a position, second innings in Brisbane, first innings in Adelaide, with decent partnerships between me and Mala [Dawid Malan], we needed to go on and we didn't.

"Sometimes that can happen, but the first 20 balls, starting your innings, you've got to be disciplined, you've got to know how you're going to get yourself in the game and we can't afford to be losing eight wickets for 70 or 80 runs.

"It is not good enough, it is not the level that an England Test team should be playing at. The guys know that and they're very aware of that. Their work ethic is very good and you'll have seen how guys practiced and how long they bat for in the nets, but sometimes I think we can be smarter about what we are practicing and how we are practicing.

"And understanding that batting, in my opinion, it's about making good decisions for long periods of time."

Dalvin Cook has been placed on the reserve/COVID-19 list by the Minnesota Vikings.

The Vikings sit second in NFC North after improving to 7-7 with a 17-9 victory over the Chicago Bears on Monday, but have suffered a major blow ahead of their clash with Los Angeles Rams in Week 16.

Mike Zimmer's side face the 10-4 Los Angeles Rams on Sunday, however, they will now likely have to turn to Alexander Mattison to lead their rushing attack in a pivotal game.

Cook's absence would rob the Vikings, who currently occupy the third and final NFC Wild Card spot with three games left, of a back who leads the NFC, and ranks third in the NFL, with 1,067 rushing yards.

Cook, who has 226 carries and six scores on the season, joins numerous Pro Bowlers who have been added to the COVID-19 list this week, including the likes of Travis Kelce and Tyreek Hill.

Mattison, who was activated from the reserve/COVID-19 list on Wednesday, is the favourite to replace Cook as the starter, though Kene Nwangwu and Wayne Gallman are on the active roster and could see a share of the workload.

Mattison has three starts this season, in which he has totalled 26 carries for 112 yards, 25 carries for 113 yards, and 22 carries for 90 yards.

The Vikings have also activated wide receiver Dan Chisena from the COVID-19 list, while they have signed running back A.J. Rose Jr. to the practice squad.

The NFL's updated COVID-19 protocols have made it easier for players to return from the reserve/COVID-19 list, provided they are vaccinated, asymptomatic, and test negative twice within one day.

Players who are not vaccinated are subject to a mandatory 10-day quarantine, which leaves uncertainty whether Cook will be back in time to face the Green Bay Packers in Week 17.

Inter defender Federico Dimarco has signed a new contract that will keep him at the club until June 2026.

The full-back has put pen to paper on his existing deal, which was due to expire at the end of next season.

The former Italy youth international first joined the club at the age of seven, but made just two senior appearances and spent time on loan at Ascoli and Empoli before departing for Swiss side Sion in 2017.

However, Dimarco returned to the San Siro a year later as Inter exercised a buy-back option, with further loan stints following at Parma and Verona.

A lifelong Inter fan, Dimarco has impressed new head coach Simone Inzaghi this season and made 24 appearances for the Nerazzurri in all competitions, scoring two goals.

"I have been going to the stadium to watch Inter games since I was two years old," Dimarco said, as quoted by Football Italia. "This is certainly not a jersey like any other for me. 

"I've been an Interista since birth and even when I was on loan at Verona, the fans kept asking me to return. I feel loved here."

Occupying the left-hand side, Dimarco has proved a constant threat for Inzaghi, who has overseen an impressive title defence so far this campaign with his side four points clear at the summit heading into Serie A's mid-season break.

Australia head coach Justin Langer backed Mitchell Starc to be fit for the Boxing Day Test, though it remains unclear whether Josh Hazlewood will feature.

Langer's side boast a 2-0 series lead after a nine-wicket demolition of Joe Root's tourists in the opening Test in Brisbane, in which Starc bowled opener Rory Burns with the first delivery of the Ashes, and a 275-run victory in Adelaide.

Starc managed match figures of 6-80 at the Adelaide Oval as Australia made it nine wins in day-night Test matches, the only side with a perfect 100 per cent winning record, in the absence of Pat Cummins and Hazlewood, who injured himself at the Gabba.

Cummins is expected to return in Melbourne after coming into close contact with a positive COVID-19 case last Wednesday, but Langer remained unsure on Hazlewood's fitness as he praised the work of left-armer Starc.

On Starc, Langer told reporters: "He should be fine. He's tough. If he's not right, then we'll look at it. But at this stage, there's no indication suggesting he won't be playing the next Test.

"I'd be very surprised if he doesn't get up for Boxing Day. We will wait and see how Hazlewood pulls up.

"I honestly thought Starc was almost the man of the match last game. He became the leader of the group.

"There's been a lot of talk about Mitch Starc for the last few years but he just keeps turning up. He's an unbelievable athlete and he's incredibly fit.

"His resilience to just keep coming up over and over and over again is remarkable really, and his consistency of length and the way he controlled the tempo of the game last game was a great credit to him, particularly with Patty (Cummins) and Hazlewood not playing."

Indeed, Starc has been the pick of fast bowlers in the series thus far, picking up nine wickets at an average of 21.33, with off-spinner Nathan Lyon the only other player to record as many dismissals (nine wickets at an average of 25). 

The hosts initially named an unchanged 15-man squad for the remainder of the Tests in Melbourne, Sydney and Hobart but have added bowler Scott Boland to the group while the medical team continue to assess the fast-bowling group.

Langer has also confirmed Marcus Harris will open in the third Test, despite the left-handed batter managing just 38 runs across four innings, knowing Australia will retain the Ashes if they avoid defeat at the Melbourne Cricket Ground.

Dawid Malan insisted the time for talking is over and England must now prove themselves in Melbourne after a dismal start to the Ashes.

England have been outclassed in the opening two Tests, suffering a 275-run defeat in Adelaide after a nine-wicket beating in Brisbane.

The tourists are without a win in 12 Tests in Australia – their joint-longest such run Down Under (also 12 between January 1937 to February 1951).

The third Test starts on Boxing Day at the MCG, with bowler Mark Wood revealing England have held "brutally honest" meetings before Saturday after disappointment last week.

Captain Joe Root also provided a scathing post-match summary of his bowlers repeating mistakes from four years ago and needing to be braver with their lengths, and batsman Malan knows it is now time for England to right their wrongs as they look to keep their hopes of regaining the urn alive.

"We've done a lot of talking," Malan told reporters. "When you lose there'll always be reports that people are at each other. There definitely isn't. 

"One of the things we've been doing this series is a lot of chat amongst the players and encouraging players to challenge each other on a lot of things. 

"We've had good discussions with the coaching staff and without the coaching staff. It's vitally important that we as players take responsibility.

"Ultimately we are the ones who walk onto the field. We get all the preparation and all the knowledge we need, it's up to us to put it in place. We haven't done that well enough. 

"When we have those honest chats as players we feel we learn a lot more. Now it's about not talking any more, it's about putting it into play."

Malan has been one of England's standout performers so far, scoring 188 runs at an average of 47, with Root (175 at an average of 43.75) in close company.

However, England's next-best batter is all-rounder Chris Woakes (105), with the trio the only players to accumulate more than 100 runs from the first two Tests.

"Everyone is up for the challenge, everyone is really keen to face up to Australia," Malan added.

"We do it in white-ball cricket, we take them on, so hopefully we can get that mindset and not go into our shells and just try to survive, take the game to them.

"We are almost learning in Test matches because we haven't had that preparation. A lot of the guys haven't played in Australia so are trying to find ways of facing bowlers they haven't faced before but also to get used to bounce here. 

"I know there's a lead-up to dismissals and how bowlers set you up, but a lot of our dismissals were probably soft in the sense that we could have left them. You still have to score, but it's about making the right choices under pressure, myself included. 

"If you look at the way they have batted, the ones who have done really well, they've left really well so it's a good learning curve for us. Hopefully it's not too late."

Andy Murray will compete at the Australian Open for the first time in three years after being awarded a main-draw wildcard.

Murray has finished as a runner-up five times at Melbourne Park – most recently in 2016 when he was beaten by Novak Djokovic 6-1 7-5 7-6 (7-3).

The Scot has since struggled with a hip injury that had him on the verge of retirement, while he dropped to 134th in the world rankings.

However, the former world number one was in action at the Mubadala World Tennis Championship in Abu Dhabi last week, where he defeated Rafael Nadal before eventually falling to Andrey Rublev in the final of the exhibition event.

Murray was due to feature at the Australian Open in 2020 before a positive coronavirus test stopped him from playing, but the 34-year-old is thankful for the chance to compete in Melbourne again.

"I'm really excited to be back playing at the Australian Open and grateful to Craig [Tiley] and the team for the opportunity," Murray said on his wildcard, as quoted by the tournament's website.

"I've had some great times in Australia playing in front of the amazing crowds and I can't wait to step back out on court at Melbourne Park."

Tournament director and Tennis Australia chief executive Craig Tiley added: "Andy is renowned for his fighting spirit, passion and love of the game, and I'm delighted to welcome him back to Melbourne in January."

American Stefan Kozlov and Frenchman Lucas Pouille join Murray as the men's singles wildcards so far, with the other four spots likely to go to Australians and another to an Asia-Pacific player.

The Australian Open gets underway on January 17 with the final set to take place 13 days later.

Joe Johnson celebrated his return to the NBA in style on Wednesday, marking a two-minute appearance with the final two points of the game as the Boston Celtics beat the Cleveland Cavaliers 111-101.

Johnson, a seven-time All-Star, was signed up by the Celtics on Wednesday on a 10-day contract, after the league granted the team a hardship waiver due to the rising amount of COVID-19 cases across the competition.

The 40-year-old has now played in 1,277 career NBA games over what is now an 18-season career, though he had last featured for the Houston Rockets in 2018.

Having joined the Celtics in the 2001 Draft as the 10th overall pick, he was let go after his rookie season, but still enjoyed a stellar career. 

Across 17 seasons from 2001 to 2018, Johnson averaged 16.0 points per game, 4.0 rebounds and 3.9 assists.

He also recorded five successive campaigns of averaging over 20.0 points per game, during a seven-season stint with the Atlanta Hawks.

When he came on for his cameo against the Cavaliers, Johnson became the second-oldest player currently in the NBA, behind Udonis Haslem of the Miami Heat.

Johnson was dubbed "Iso Joe" due to his prowess in one-v-one situations throughout his career, and the veteran showed that skill had not gone away as he outjumped Justin Anderson to add the final two points onto Boston's score on Wednesday.

"It's amazing to be back here 20 years later," Johnson, who is the only current NBA player to have played against the legendary Michael Jordan, told reporters.

"It's still surreal to me. To come into the game and be somewhat effective, that's fun.

"At my age you try to relish every moment, enjoy the process and live in the moment. That's kind of what I'm doing right now, living in the moment and it's fun."

Johnson knows, however, that he has been given an unlikely opportunity.

"I wouldn't say give up, but I didn't have high hopes," Johnson added. 

"My son's 14, so he keeps me in the gym. We work and work and work, and I always talk to him [and say], "just work". Even when you can't see what's next, you just gotta continue to work."

Johnson was only notified of the possible deal with the Celtics on Tuesday, and shortly after was on a flight to Boston.

"It was a no-brainer for me," he said. "I'm a guy who really takes care of his body. I'm in pretty good shape. So I felt like I was ready to take on that challenge.

"So [my agent] asked me what I thought, and we just kept moving. I'm ready for whatever comes my way."

"He's still got a lot in the tank if you ask me," said Jaylen Brown, who scored a team-leading 34 points for Boston.

"I've watched him in the Big3, I've watched him before that, and I watched him growing up and he still looks like he's got something left in the tank so I'm happy to have him on board, to hear his voice, his advice. I think it's great."
