Steve Nash is eyeing a championship with the Brooklyn Nets after the arrival of James Harden, but the head coach warned his team they needed to improve.

Harden, an eight-time All-Star, was traded to the Nets from the Houston Rockets on Thursday, joining Kevin Durant and Kyrie Irving in Brooklyn.

The Nets (7-6) are set to contend for a first NBA championship and Nash said there was a huge opportunity ahead.

"We want to win a championship, for sure. That's why we made the deal, that's what we're setting out to do," he told a news conference.

"Having said that, we're so far from that right now so our expectations are to grow every day, to get better, to figure out who we are and what we are and how we fit together and where we can improve. It's a process.

"You have to earn the right to play for a championship through the regular season and playoffs so those steps are still in front of us before we can say we're a championship team.

"We're not a team that's running it back that's been to the Finals or Conference Finals even, we're a brand new entity that has to figure it out but that is the end goal and if we take the necessary steps and continue to improve and work towards that and commit to that process, why not? We have a great opportunity here with the players we have."

With Durant and Harden, the Nets now have two players who have won seven of the past 11 NBA scoring titles. No Brooklyn qualifier has ever finished higher than fifth.

Irving, Harden and Durant all rank in the top 10 in the NBA in scoring average (minimum 500 games) since the former's rookie season in 2011-12.

Harden could make his Nets debut against the Orlando Magic on Saturday.

The Los Angeles Lakers cruised to a victory in the NBA, while the Milwaukee Bucks and Boston Celtics also extended their winning streaks.

LeBron James had a double-double of 21 points and 11 assists as the Lakers recorded a comfortable 112-95 win over the New Orleans Pelicans on Friday.

Kyle Kuzma contributed 11 points and 13 rebounds off the bench, while Anthony Davis struggled from the field, shooting five-of-16 for his 17 points.

Pelicans star Zion Williamson finished with 21 points and 12 rebounds, but the Lakers extended their winning streak to five.

Giannis Antetokounmpo's 31 points and nine rebounds helped the Bucks overcome the Dallas Mavericks 112-109.

Luka Doncic fell just short of a triple-double, contributing 28 points, 13 assists and nine rebounds in the Mavericks' loss.

The Bucks (9-4) have won four straight to sit behind the Celtics (8-3) in the Eastern Conference.

Brown leads returning Celtics, Drummond stars

Jaylen Brown had 21 points and eight assists in the Celtics' 124-97 win over the Orlando Magic. It was Boston's first game in a week.

A huge double-double of 33 points and 23 rebounds from Andre Drummond saw the Cleveland Cavaliers edge the New York Knicks 106-103.

The Los Angeles Clippers thrashed the Sacramento Kings 138-100 thanks to 27 points, six assists and four rebounds from Kawhi Leonard.

Shai Gilgeous-Alexander posted 33 points and 10 assists in the Oklahoma City Thunder's 127-125 victory over the Chicago Bulls.

Bulls' narrow losses continue

The Bulls are on a four-game losing streak, with those defeats coming by four, two, three and two points. It is the first time in team history they have lost four in a row with each loss by four points or fewer, as per Stats Perform. The last team with a streak that long was the Washington Wizards in 2009 (six straight).

Drummond dynamite

Drummond produced a huge performance for the Cavs. He was 10-of-18 from the field and 16 of his 23 rebounds were on the defensive end.

Friday's results

Boston Celtics 124-97 Orlando Magic
Cleveland Cavaliers 106-103 New York Knicks
Milwaukee Bucks 112-109 Dallas Mavericks

Magic at Nets

James Harden is set to make his debut for the Brooklyn Nets (7-6) against the Orlando Magic (6-6) on Saturday. Harden's trade from the Houston Rockets to the Nets was confirmed on Thursday.

James Harden believes he will combine well with Kevin Durant and Kyrie Irving at the Brooklyn Nets, talking up the "sacrifice" that would be required.

Harden, an eight-time All-Star, was traded from the Houston Rockets to the Nets in a move that was confirmed on Thursday.

Amid questions over how Harden will fit alongside Durant and Irving, the Nets recruit is confident – and said there would need to be sacrifices.

"Chemistry, sacrifice and like you said we're all elite so depending on the game, depending on what's going on throughout the course of the game, that's going to determine who gets the ball and who makes the plays," Harden told a news conference on Friday.

"We're all unselfish, we're all willing passers and we play basketball the right way and that's all that matters."

Asked what the Nets fans were getting, Harden said: "An elite player, an elite team-mate, an elite leader and just a guy that is willing to do whatever it takes to rack up as many wins as we can, sacrifice."

Harden's arrival enhances the Nets' championship hopes as the 31-year-old looks to win a maiden NBA title.

With Durant and Harden, the Nets now have two players who have won seven of the past 11 NBA scoring titles. No Brooklyn qualifier has ever finished higher than fifth.

Irving, Harden and Durant all rank in the top 10 in the NBA in scoring average (minimum 500 games) since the former's rookie season in 2011-12.

Harden said the Nets (7-6) were in position to contend.

"Obviously you've got Kevin Durant and Kyrie Irving on the team and then surrounded by those guys you have really good pieces in DeAndre [Jordan], Jeff [Green], shooters in Joe [Harris], Landry [Shamet]," he said.

"You just look at this entire roster and it's built for any style of basketball you want. And then the coaching staff who know the game of basketball at a high level.

"You just add that all together and that's a legit chance right there. It was a no-brainer for me."

Kyrie Irving is counting the cost of attending a party last weekend after the Brooklyn Nets star was handed sanctions that looks set to leave him almost $900,000 out of pocket.

The NBA declared on Friday that it had imposed a $50,000 fine on Irving, who according to TMZ and widespread reports attended a large family birthday celebration while not wearing a mask.

That was in contravention of the league's coronavirus protocols.

But that penalty is just the tip of a very large iceberg, as Irving also must sacrifice his salary for the games he has since missed while quarantining, and according to ESPN's Bobby Marks that amounts to $816,898 in addition to the fine.

In a statement, the NBA said: "Brooklyn Nets guard Kyrie Irving has been fined $50,000 for violating the league's health and safety protocols, which among other things prohibit attending indoor social gatherings of 15 or more people or entering bars, lounges, clubs or similar establishments, it was announced today by Byron Spruell, president, league operations.

"The violation occurred when he attended a private indoor party last weekend.

"Irving will forfeit salary for any games he misses due to his five-day quarantine period, which will allow him to return to team activities on Saturday, January 16 if he continues to test negative."

Irving has averaged 27.1 points in his seven NBA appearances for the Nets this season, but for personal reasons he has not played in the team's most recent five games.

The 28-year-old six-time NBA All-Star joined the Nets in 2019 from the Boston Celtics and began his career with the Cleveland Cavaliers, landing a 2016 championship with the Cavs.

The Nets face the Orlando Magic on Saturday.

The New York Yankees are reportedly finalising a deal to re-sign second baseman DJ LeMahieu.

According to Jeff Passan of ESPN, LeMahieu is set to sign a six-year, $90million contract to stay in the Bronx.

That payday follows a stellar second season with the Yankees, who reached the American League Divisional Series but lost to the Tampa Bay Rays in five games.

LeMahieu finished the season with 10 home runs and 27 RBIs, leading MLB with a batting average of .364.

He was also first in the American League in on-base percentage (.421) and on-base percentage plus slugging percentage (1.011).

The infielder's efforts saw him finish third in the American League MVP voting and he was the second base silver slugger for the second straight year.

The Yankees are due to begin their spring training schedule on February 27 against the Detroit Tigers. Their regular season is scheduled to get under way on April 1 with a meeting with the Toronto Blue Jays.

Portland Trail Blazers center Jusuf Nurkic is set for another spell on the sidelines after suffering a right wrist fracture on Thursday.

Nurkic left the Trail Blazers' 111-87 defeat to the Indiana Pacers in the third quarter after hurting his arm while swiping at Malcolm Brogdon.

The 26-year-old Bosnian suffered a broken leg in 2019 and spent over a year out, only returning in July last year after the season was suspended due to the coronavirus pandemic.

Head coach Terry Stotts was planning to discuss whether Portland should bring in another big with general manager Neil Olshey on Friday, given Zach Collins is already out due to an Achilles problem.

"I did see [Nurkic] after the game. He had a splint on, so obviously very disappointing for him and for us," said Stotts.

"He had a long road back from his other injury, he had a rough start to the season, it looked like he was getting back on track and obviously this is a huge setback for both him and for us.

"I'm going to sit down with Neil tomorrow and we'll talk about what options we have.

"Most likely [Enes Kanter will start], but we'll evaluate that. Obviously, Harry Giles is going to get an opportunity to play and we'll figure out whether it's best to start him or bring him off the bench, but we'll see."

Nurkic averaged 9.8 points and 7.7 rebounds through 12 games this season. He had five points on 2-of-8 shooting and eight rebounds before leaving the game against the Pacers.

Damian Lillard called on his fellow Trail Blazers to rally together and fill the void that Nurkic's absence creates.

"We've got to show our love for him but also give him his space. It's hard to deal with when the game we love to play and is part of our lives every day is taken away abruptly," said Lillard.

"We're always going to be here for him. It's a tough thing. It comes with what we do and it can happen at any time.

"[He was] frustrated, disappointed, a little sad, like anyone would be in that situation.

"He plays a major part in our team and our success. Obviously you're not going to have one person turn into Nurk, it has to be by committee. In the past we've been able to count on guys to come in and fill those holes collectively and that's what we'll be looking at now."

CJ McCollum added: "It's terrible. He's a huge part of our team. Obviously he's been through a lot historically with injuries, so you never want to see it with anybody, especially him.

"It's tough. The season still goes on, it waits for no one, so we have to figure out a way to continue to move forward.

"Enes has been big for us in the past so will have to step up, Harry will have to play, some small ball, we'll do a lot of different stuff. It's an unfortunate part of the game but it's a challenge and I'm looking forward to seeing how we respond to it."

Stephen Curry's 35 points were not enough for the Golden State Warriors, while the Houston Rockets started the post-James Harden era with a win.

Curry was 14-of-23 from the field and five-of-11 from three-point range, but the Warriors fell to the Denver Nuggets 114-104 on Thursday.

Nuggets star Nikola Jokic dominated with a triple-double of 23 points, 14 rebounds and 10 assists.

Denver had seven players in double-digits for points as they improved to 6-6 – the same record the Warriors now hold.

After trading Harden to the Brooklyn Nets, the Rockets recorded a 109-105 win over the San Antonio Spurs.

Christian Wood had a double-double of 27 points and 15 rebounds for the Rockets, who were without John Wall (knee).

Milton magical for Sixers, Boucher lifts Raptors

Shake Milton had 31 points off the bench in the Philadelphia 76ers' 125-108 win over the Miami Heat. He was 11-of-15 from the field and three-of-four from three-points range.

Ben Simmons notched a triple-double of 10 points, 12 assists and 10 rebounds for the 76ers. Only Oscar Robertson (75 games) and Magic Johnson (190 games) have reached 30 career triple-doubles quicker than Simmons (228).

Chris Boucher had 25 points and 10 rebounds off the bench to help the Toronto Raptors beat the Charlotte Hornets 111-108.

A huge game from Domantas Sabonis (23 points and 15 rebounds) saw the Indiana Pacers past the Portland Trail Blazers 111-87.

After another four blocks and one steal, Pacers center Myles Turner reached 50 blocks and 18 steals through 12 games. He is the first player to have at least that many blocks and steals through his first 12 games of a season since David Robinson in 1992-93, as per Stats Perform.

Job done for 76ers despite Embiid struggles

Joel Embiid has enjoyed a superb start to the season, but the 76ers star struggled against Miami. He was three-of-eight from the field for just nine points in 23 minutes.

Bridges brilliance

Miles Bridges produced a huge dunk during the Hornets' loss to the Raptors. He finished with 12 points.

Thursday's results

Philadelphia 76ers 125-108 Miami Heat
Toronto Raptors 111-108 Charlotte Hornets
Houston Rockets 109-105 San Antonio Spurs
Indiana Pacers 111-87 Portland Trail Blazers
Denver Nuggets 114-104 Golden State Warriors

Pelicans at Lakers

The Los Angeles Lakers (10-3) are riding a four-game winning streak ahead of hosting the New Orleans Pelicans (4-6) on Friday. LeBron James is averaging 24.3 points, 8.1 rebounds and 7.5 assists per game to begin the campaign.

Ben Simmons insisted he was unfazed about talk over his future with the Philadelphia 76ers after James Harden joined the Brooklyn Nets.

Simmons was the subject of trade rumours as the 76ers were linked to Harden, whose move from the Houston Rockets to the Nets was confirmed on Thursday.

But, after the 76ers' 125-108 win over the Miami Heat on Thursday, the 24-year-old said it was just part of the game.

"This is a business, things like that happen," Simmons told a news conference.

"The only thing I can control is how I approach my workouts, the games and my day-to-day things.

"I'm just trying to be professional and do the right thing and help my team get wins."

Asked if he was happy to be in Philadelphia, Simmons responded: "Of course."

Simmons posted a triple-double of 10 points, 12 assists and 10 rebounds in the win over the Heat.

It was his 30th triple-double in the NBA. Only Oscar Robertson (75 games) and Magic Johnson (190) have managed that quicker than Simmons (228).

Philadelphia head coach Doc Rivers was delighted with Simmons' performance as the 76ers improved to 9-4.

"I thought tonight is who he has to be every night. I loved the way he played. I loved how he played under control, didn't force it, took gaps when they were there," he said.

"He was a presence on the floor for us and not just on the offensive end but on the defensive end as well and that takes us to a different level when he plays like that."

Brooklyn Nets general manager Sean Marks is confident Kevin Durant, Kyrie Irving and James Harden will gel as they work towards a "common goal".

The Nets confirmed on Thursday they had completed a blockbuster trade to land eight-time All-Star Harden from the Houston Rockets.

Questions have been asked over whether Durant, Harden and Irving can work together, but Marks is confident.

"These guys have given us the right answers. They've said hey, they want to play together, they can see this fitting," he told a news conference.

"They're at a time in their careers – I don't want to speak for each one of them because I let them have their own their own voice and their narrative around this – but I think they understand that there's without a doubt going to be some nights where one or two need to sacrifice for the other and so forth. But I think they're all looking for a common goal.

"We’re all looking for that common goal, as I've said before, is to be the last team standing. I think when you have a group that is willing to sacrifice, and play hard, play together on the court, and they already have a relationship, a prior relationship to this, so I think that will help."

Harden, Durant and Irving all rank in the top 10 in the NBA in scoring average since the latter's rookie season in 2011-12 (minimum 500 games).

Durant or Harden have won seven of the past 11 NBA scoring titles. No Brooklyn qualifier has ever finished higher than fifth in the league.

Marks said the opportunity to land a player like Harden came at a good time for the Nets.

"The timing was right for us. And fortunately, any time you get an opportunity to acquire or try to acquire a player of this calibre it's something you do look hard at [and] is something we did," he said.

"The process sped up very, very rapidly and very quickly over the last 48 hours."

Madison Keys is set to miss the Australian Open after testing positive for coronavirus.

The 2017 US Open runner-up announced on Thursday that she contracted COVID-19 before she was due to fly out for the first grand slam of the year.

Keys did not state she will definitely miss the major, which starts on February 8, but it appears the American will not make the trip to Melbourne.

The American wrote on Instagram: "Hi everyone, I wanted to let you know that I unfortunately tested positive for COVID-19 before I was supposed to fly to Australia.

"I'm very disappointed to not be able to play in the coming weeks after training hard in the off-season and knowing Tennis Australia and the tours did so much to make these events happen.

"I am self-isolating at home and will continue to follow all the necessary health precautions. I look forward to being back on tour next month."

It was revealed earlier in the day that three-time major winner Andy Murray has also tested positive for the virus, but still hopes to play in the Australian Open.

Meanwhile, world number 50 Tennys Sandgren was cleared to board a flight from the United States bound for Melbourne despite revealing he returned a new positive coronavirus test this week. 

The American, twice a quarter-finalist at Melbourne Park, initially posted to social media on Wednesday that he had tested positive for the virus for a second time. 

Although his first instance of having the illness was recorded in November, the 29-year-old's participation in the tournament appeared to be in doubt. 

But as he continued to update followers through the day, it emerged he had been allowed to board his flight. 

Players will only be allowed into Australia with proof of a negative test just prior to departure, or with approval to travel as a recovered case at the complete discretion of an Australian government authority.

Anyone wanting to travel out for the tournament who previously tested positive is required to provide additional and highly detailed medical information as proof they are a recovered case and no longer infectious or a risk to the community.

James Harden has been thanked by the Houston Rockets after being traded to the Brooklyn Nets.

Three-time NBA scoring champion Harden has linked up with former Oklahoma City Thunder team-mate Kevin Durant and Kyrie Irving in Brooklyn, who have gone all in on a championship run by bringing in the 2018 MVP.

The Nets gave up Jarrett Allen, Taurean Prince, Caris LeVert, Radions Kurucs, three first-round draft picks (2022, 2024 and 2026) and four first-round pick swaps (2021, 2023, 2025 and 2027) to acquire Harden.

Allen and Prince were sent to the Cleveland Cavaliers, who provided Houston with Dante Exum and a 2022 first-round pick via the Milwaukee Bucks. Brooklyn received a 2024 second-round pick from the Cavs to complete the deal.

The Rockets are expected to send LeVert and a 2023 second-round pick to the Indiana Pacers in exchange for two-time All-Star Victor Oladipo.

Harden requested a trade prior to the start of the season and following a 117-100 loss to the Los Angeles Lakers on Tuesday he said: "It's something that I don't think can be fixed."

The Rockets granted their franchise player his wish on Thursday and owner Tilman Fertitta praised him for his achievements in Houston.

"On behalf of the entire Rockets organisation and the City of Houston, I'd like to thank James Harden for an amazing eight-plus seasons in a Rockets uniform," said Fertitta in a statement.

"James has provided us with so many great memories as we've watched him grow from Sixth Man of the Year to a perennial All-Star and MVP.

"My family and I also want to thank James for his many off the court contributions, including generous charitable donations and multiple annual community events.

"We wish James the best of luck and will always be grateful for the memories."

Harden is second on the Rockets' all-time scoring list with 18,365 points, only trailing Hakeem Olajuwon (26,511) – a two-time NBA champion in Houston.

He averaged 29.6 points, 6.0 rebounds and 7.7 assists during his time with the Rockets.

Harden led them to the Western Conference Finals in 2014-15 and 2017-18, losing to the Golden State Warriors on both occasions.

LaMelo Ball's NBA career with the Charlotte Hornets got off to a subpar start. 

In fact that might just be a generous description of his NBA debut. It was downright brutal. 

The third overall pick of this year's draft played a scoreless 15 minutes in his first game, missing all five of his field-goal attempts in Charlotte’s 121-114 loss to the Cleveland Cavaliers on December 23. 

Not only did he fail to score, the highly-touted playmaker also turned the ball over three times, becoming only the second player in the last 35 years to finish without a point while taking at least five shots with three or more turnovers in 15-plus minutes in their NBA debut, joining the Golden State Warriors' Brandon Williams in 1998. 

While he got off to a shaky start, things have since gone much better. 

Better actually might not be kind enough in describing his recent play. He's been outstanding. 

On the onset of the 2020 draft, the 6-foot-7 point guard was widely considered to have the highest ceiling of all the prospects. An adept ball-handler, scouts marvelled at his passing, court vision and his ability to push the ball up the court. 

Though Ball possesses an immense skillset and has a comprehensive understanding of the game, making the jump from Australia's National Basketball League to the NBA would admittedly take time. 

It took him all of one week. 

With 22 points, eight rebounds and five assists in a win over the Dallas Mavericks on December 30, he became the first player in the last 35 years to reach those numbers in just his fourth game, and he's continued to stuff the stat sheet with impressive numbers. 

Since then, he's had two more games with 15 or more points, eight or more rebounds and five or more assists. Only four other players have had more such games in that span – the Denver Nuggets' Nikola Jokic (six), Mavericks' Luka Doncic (five), New York Knicks' Julius Randle (five) and Los Angeles Lakers' LeBron James (four). 

Over the course of three games from January 8-11, he racked up 42 points, 36 rebounds and 27 assists, joining Ben Simmons in 2017 and Lamar Odom in 2000 as the only rookies in the last 35 years with at least 40 points, 35 boards and 25 assists over a three-game span. 

In the middle game of that three-match stretch, Ball made history. At 19 years and 140 days, he became the youngest player ever to record a triple-double by notching 22 points, 12 rebounds and 11 assists in Saturday's win over the Atlanta Hawks. 

Despite stumbling out of the gate with his forgettable debut, he still reached the 10-game mark with 131 points, 63 rebounds and 59 assists. In the last 35 seasons, only two other rookies have reached those numbers after 10 games – James in 2003 and Simmons in 2017. 

Ball's passing has been as advertised. He's finding his open team-mates and setting them up for success. 

Among the 100 players with at least 30 assists, he has the league's 10-best assist rate – the estimation of percentage of field goals made by team-mates while he's on the floor. At 36.8 per cent, Ball sits just a bit back of James, whose eighth at 37.6. 

With 71 assists on the season, Ball has eight fewer assists than Devonte' Graham for the most on the Hornets. He does, however, lead Charlotte with 84 rebounds, and if he does surpass Graham and finish the season leading the team in both rebounds and assists, he'll join Michael Jordan in 1984-85 and Blake Griffin in 2010-11, as the only rookies in the last 40 years to lead their team in both categories. 

Not only is Ball flourishing in the part of his game many thought he would eventually excel in, he is also finding success in areas that were believed to be some of his biggest weaknesses – shooting and defense. 

After shooting a dreadful 24 per cent from 3-point range in Australia's NBL, Ball is making a respectable 33.9 per cent of his 3s. Nothing outstanding, but the league average on 3s is 36.6 per cent. 

He’s also showing a proficiency at knocking down shots just inside the arc. His 50 per cent shooting on mid-range jumpers is tied with seven others for 17th in the NBA among those with at least 100 field-goal attempts. 

Defense was another area that many expected would take Ball time to grasp and be competent in, but he’s already proven to be up to speed, leading all rookies with 22 defensive stops. 

Not only does he lead all first-year players in defensive stops, he also leads all rookies in points (143), rebounds (84), assists (71), as well as steals (18). 

If Ball continues to thrive on the court and finishes the season leading all rookies in points, rebounds and assists, he’ll become just the seventh player in NBA history to accomplish that feat, joining Elgin Baylor (1958-59), Wilt Chamberlain (1959-60), Oscar Robertson (1960-61), Walt Bellamy (1961-62), Alvin Adams (1975-76) and Michael Carter-Williams (2013-14). 

Not surprising, but each of the previous six won the Rookie of the Year Award. 

Playing at a level few rookies have before him, Ball is the early frontrunner to win this season's award. 

Good thing for him the trophy isn't handed out after one game.
