LeBron James has not been doing anything different in recent matches but the Los Angeles Lakers' shooters have "come alive" since the All-Star break, says head coach Frank Vogel.

Superstar James registered a second consecutive triple-double in as many nights as the Lakers outclassed the NBA-worst Minnesota Timberwolves 137-121.

James, who had 22 points, 11 assists and 10 rebounds, now needs just one more to rack up a landmark 100th career triple-double, while it marked his fifth of this season.

Prior to the All-Star game, the Lakers had lost six times in eight games but are now on a three-game winning streak, with James at the heart of team's impressive fortunes.

But Vogel insists it is merely a case of the team being hotter with the ball, saying: "I honestly don't think [James] has been playing that differently than what he was doing leading into the break

"I just think our shooters have come alive. I think we hit a little bit of a wall coming into the break, and then our shooters got their legs under them a little bit, and in the last three games they've been hitting shots, so his assist totals are up."

Several players contributed for the Lakers, with Dennis Schroder putting up 16 points and seven assists, while Kyle Kuzma also had 16 points.

Youngster Talen Horton-Tucker followed up an 18-point showing versus the Golden State Warriors with 16 points, seven rebounds and four assists.

The last two games have seen Horton-Tucker excel against two 2020 first-round draft picks in James Wiseman and Anthony Edwards, and James said the 20-year-old – selected in the second round in 2019 – will only continue to grow in stature.

"It's something we've talked about all year, if you go back to the draft Talen Horton-Tucker would not go in the second round," James said about his team-mate. 

"We're super-duper lucky and blessed to grab him when we grabbed him. His ability to get downhill, his ability to get to the lane and finish or his ability to make the extra passes, he's a big guard, but with great handle and great balance. 

"This is Talen's rookie year too pretty much, he's learning, he'll continue to get better, he's a damn good player right now he'll continue to get better and better."

Damian Lillard described the process required to become a lethal shooter after scoring a season-high 50 points, with the Portland Trail Blazers star lauding Stephen Curry as the greatest in the NBA.

Lillard's haul included 20 in the final quarter as Portland secured a stunning 125-124 comeback victory over the New Orleans Pelicans, having been 17 points behind in the fourth.

The Pelicans were inspired by Lillard's glorious display as he added 10 assists and six rebounds, finishing 18 of 18 from free-throws.

Lillard is now tied with LeBron James in seventh for all-time most 50-point NBA games, while he became only the fourth player to have racked up at least 16,000 points and dished out at least 4,000 assists in their first nine seasons.

Asked by the TNT post-match team how he became such a brilliant shooter, Lillard emphasised the work ethic needed and singled out Golden State Warriors hero Curry as the best in the business.

"It's just putting a lot of time into it," he said.

"We got some great shooters in our league. Obviously we think of Steph Curry first when we think of shooters, the greatest shooter to ever play in our league.

"He'll tell you the same thing, that it's a lot of reps. Whether people are watching or whether you get credit for it or not, you put the time in and you do it at a game pace, you do it with focus, you do it where you hold yourself to a certain standard.

"You make 10 in a row at each spot at the end of your workout when you're tired and you probably don't want to do it, it's things like that over and over again over the years.

"You get better from the reps, but more so than physically you get better mentally and more confident in it because you've done it so often and you've done it when you're tired, you've done it when you didn't want to.

"Then in the moments – whether it's first quarter, second quarter, third quarter, a tough shot, an easy shot – you've got the ultimate confidence that it's going to go in.  

"I think confidence is the biggest thing for shooters, right next to just getting the reps in and knowing in your heart that you didn't cheat it, you put the time in and you deserved to make those shots and you expect that result."

The win improved Portland's record to 23-16 as they remain firmly in playoff contention, while the Pelicans slipped to 17-23, despite Lonzo Ball's career-high 17 assists.

Damian Lillard scored a season-high 50 points, including 20 in the last quarter, as the Portland Trail Blazers produced a remarkable comeback to snatch a last-gasp 125-124 win over the New Orleans Pelicans on Tuesday.

The Pelicans led by 17 points late in the third term and Brandon Ingram had the chance to ice the game late on, before missing two free-throws as Portland snatched victory.

Lillard was the catalyst with his 20 final-quarter points, totalling 50 for the game, along with 10 assists and six rebounds. He also finished with six three-pointers and 18 of 18 free-throws.

He coolly scored two free-throws after Nickeil Alexander-Walker's costly fumble turned over possession. Zion Williamson had one last chance to steal victory but missed from a good close look.

The result improved Portland's record to 23-16 as they stay firmly in playoff contention while the Pelicans slipped to 17-23, despite Lonzo Ball's career-high 17 assists.

Lillard is now tied with LeBron James in seventh for all-time most 50-point NBA games.

Meanwhile, James had the 99th triple-double of his career with 25 points, 12 rebounds and 12 assists, while Montrezl Harrell was equal top scorer for the Los Angeles Lakers in a 137-121 win over the Minnesota Timberwolves.

Smooth Jazz back among winners

Rudy Gobert scored 11 of his 16 points in the final period as the Utah Jazz bounced back from their loss to the Golden State Warriors with a 117-109 win over the Boston Celtics.

Gobert, who also had 12 rebounds, was well supported by Donovan Mitchell (21 points and five assists) and impressive sixth man Jordan Clarkson (20 points and three assists) as the Jazz stormed home to edge past Boston.

Without Joel Embiid, Tobias Harris stepped up for the Philadelphia 76ers with 30 points in a thrilling 99-96 triumph over the New York Knicks.

Ben Simmons had 16 points, 13 rebounds and seven assists for the 76ers, who trailed by nine at the final change before a dominant fourth quarter.

Jimmy Butler starred with 28 points, 12 rebounds and four assists as the in-form Miami Heat made it five wins in a row with a 113-98 victory over the Cleveland Cavaliers.

Miami center Bam Adebayo also returned from injury with 14 points, nine rebounds and six assists.

Nate McMillan is yet to lose as head coach at the resurgent Atlanta Hawks, who claimed their sixth consecutive win, beating the Houston Rockets 119-107, led by Danilo Gallinari with 29 points.

No lift-off as Rockets grounded

While Atlanta have turned their season around with a coaching change, Houston have now lost 17 in a row. Stephen Silas is left scratching his head, with his side going from 11-10 to 11-27.

Big blocks

There were some huge blocks on Tuesday but 76ers veteran Dwight Howard stole the show early in the fourth, putting Julius Randle on the floor with an emphatic swat.

Bucks at 76ers

The 76ers, without the injured Embiid, take on Giannis Antetokounmpo's Milwaukee Bucks in a blockbuster clash on Wednesday.

Italian qualifier Lorenzo Musetti may be ranked 120th in the world but he claimed his maiden top-10 scalp on Tuesday, beating Diego Schwartzman in the first round of the Mexican Open.

Musetti, the Australian Open boys' singles champion in 2019, secured a 6-3 2-6 6-4 win over ninth-ranked Schwartzman in a stunning success.

"There is a lot of work, a lot of sacrifice and I think some tears left in my eyes," the 19-year-old said during his on-court interview.

"I'm really proud of myself, but now I'm going to work harder and focus on the next days."

Musetti, whose forehand was excellent, defeated both Stan Wawrinka and Kei Nishikori at the Internazionali d'Italia in Rome last year.

Top seed Stefanos Tsitsipas had no such trouble, easing into the second round, where he will face big-serving American John Isner.

The Greek world number five beat France's Benoit Paire 6-3 6-1, aided by a strong display on serve.

"I didn't know what to expect from Benoit today," Tsitsipas said. "I think it's kind of tricky playing a tournament you haven't played before."

On facing 27th-ranked Isner next up, Tsitsipas added: "He's a guy that serves really well so that's going to be the biggest element and the one thing that I'll really have to resolve during that match."

Fourth seed Milos Raonic sent down 13 aces as he defeated American Tommy Paul 7-6 (8-6) 6-4.

In the late match, fifth seed Grigor Dimitrov got past Adrian Mannarino, who retired when trailing 6-4 3-0.

Former US Open champion Sloane Stephens has continued her torrid start to 2021 after crashing out in the first round of the Monterrey Open on Tuesday.

Stephens went into the Mexico event as top seed but lost to Slovakian world number 151 Kristina Kucova 6-2 6-2.

The 27-year-old American is now 0-4 to start the 2021 WTA Tour season and has won only one set all season.

Stephens, now ranked 48th in the world, only managed to win 32.4 per cent of points on her first serve, with Kucova converting seven of 14 break points in the match.

Second seed Nadia Podoroska was also a first-round casualty on Tuesday, going down 6-4 6-4 to Russian qualifier Anna Kalinskaya.

In the late match, Eugenie Bouchard went down to China's Lin Zhu 7-5 7-6 (6-3).

Matteo Guendouzi insists his Arsenal career is not over and he wants to fight his way back into Mikel Arteta's plans next season.

Guendouzi, 21, has been on loan with Hertha Berlin since last October where he has made 19 appearances for the Bundesliga club.

The French midfielder was a regular starter with the Gunners under previous boss Unai Emery but failed to make an appearance for Arteta's side in the opening weeks of the season prior to securing a temporary move away.

When asked if his Arsenal career was over due to an apparently strained relationship with Arteta, Guendouzi was emphatic in his response.

"No, not at all," he told France Football.

"I am focused on my season at Hertha Berlin. Then, we will make a point with my agent and the people of the club to sit down and discuss the future. I am still an Arsenal player."

Guendouzi joined Arsenal from Lorient in 2018 and has made 57 Premier League appearances for the Gunners, registering just one assist and no goals in the competition.

In those games he attempted a total of 75 tackles, the third-most among Arsenal players across 2018-19 and 2019-20, while his 263 duel wins over the same period was only bettered by four of his team-mates.

His contract with Arsenal expires at the end of next season and he acknowledged his long-term future will be at stake when he returns to the Gunners.

"This summer will be a decisive moment," he added.

"Could I come back to the club with Mikel Arteta on the bench as coach? Yes, of course. I will be with Arsenal for another year.

"I am here to move forward. When I played for Arsenal, I have always given everything for this club, for these fans, for the team, for the staff. I will work hard for the jersey as usual."

Top seed Dominic Thiem was beaten in straight sets in the second round of the Dubai Tennis Championships by Lloyd Harris.

The reigning US Open champion, given a bye for the first round, lost 6-3 6-4 to his South African opponent, who sits 77 places further down the ATP rankings.

The Austrian has endured a difficult start to 2021. He lost in straight sets to Grigor Dimitrov in the last 16 of the Australian Open and was beaten by Roberto Bautista Agut in the quarter-finals in Doha.

It was a first win over a top-five player for Harris, who was not once taken to deuce on serve during their 72 minutes on court.

"I'm super, super happy with that win. [He is] by far the highest-ranked player I have beat," said Harris. "I look up to Domi a lot so, for me, it is a special feeling. I am really happy. Just the fact that I am playing good tennis, match in, match out now is giving me a lot of confidence.

"I was serving really well. I don't think I faced any break points. I took control of those games and [in] one or two games on his serve, I gave myself a good look. I played some of the important points very well. I am very proud of that."

While Thiem is struggling for form, things are looking far better for Andrey Rublev, who beat Emil Ruusuvuori 6-4 6-4 to stretch his winning streak at ATP 500 events to 21 matches.

The world number eight, who will face Taylor Fritz in the next round, equalled Andy Murray for the second-best winning run at this level of the Tour. Roger Federer (28) holds the record.

Third seed Denis Shapovalov beat Jan-Lennard Struff for the loss of just four games, while Bautista-Agut advanced after opponent Matthew Ebden retired in the first set.

Fifth seed David Goffin was beaten in straight sets by Kei Nishikori, who recorded just his third victory of the year.

Karen Khachanov and Jannik Sinner each advanced after three-setters, while Marton Fucsovics and Aslan Karatsev were also taken the distance before progressing.

Hubert Hurkacz, Lorenzo Sonego, Dusan Lajovic, Aljaz Bedene and Filip Krajinovic also won on Tuesday.

Juan Bernat has signed a new four-year contract with Paris Saint-Germain.

The left-back is nearing the end of his third season with PSG having signed from Bayern Munich in 2018.

Bernat, 28, was due to be out of contract at the end of 2020-21 but will now be tied to PSG until June 2025.

He has not played since last September due to an ACL injury.

PSG sporting director Leonardo had publicly stated he was targeting four big contract renewals for the French champions – Angel Di Maria, Bernat, Neymar and Kylian Mbappe.

Di Maria and Bernat are done, meaning the attention moves fully to the two star forwards, particularly with huge speculation the club will pursue Lionel Messi when his Barcelona contract expires at the end of the season.

"I am very happy to have been able to extend my contract with Paris, I have always said that I feel good here," Bernat said after his new deal was announced on Tuesday.

"I really wanted to continue my adventure with the club, it's now happened and I am very happy about it.

"It's a bit of everything, it's the club, it's the affection that everyone shows me here, the supporters, my team-mates. 

"There is a really exciting project here and I am happy to be a part of it.

"I think that we can achieve great things together, that's one of the reasons that I wanted to continue my time here at the club, and I hope to be able to play here for several more years."

Bernat is hoping to return before the end of the season, with PSG three points behind Lille at the top of Ligue 1 and in the Champions League quarter-finals.

The Valencia youth product added: "The league is very tight this year, we are just three points behind the leaders and I hope we will make up these points. 

"I also hope to be available for the final games and to help the team. For the moment, we can only think about working hard and winning each match."

Daria Kasatkina fended off fast-rising star Clara Tauson at the St Petersburg Ladies Trophy as the Russian home favourite edged a clash of recent tournament winners.

Former world number 10 Kasatkina, who landed the Phillip Island Trophy title in Melbourne last month, came through a roller coaster second set against the qualifier to tie up a 6-4 7-6 (7-0) first-round victory.

Former junior world number one Tauson won the Lyon Open at the start of March, and the 18-year-old Danish player twice broke when Kasatkina was serving for the match to take their tussle to a tie-break that was then unexpectedly one-sided.

Having been jittery when serving at 5-4 and 6-5, Kasatkina found composure when it mattered to see out the match.

Tauson had won 13 consecutive matches, including qualifiers, and had reeled off 20 successive sets during that run, but Kasatkina interrupted the hot streak.

Three-time WTA tournament winner Kasatkina, seeded eighth this week, said on Amazon Prime: "You're right, I was nervous serving for the match, but I'm glad I could close out the match playing the tie-breaker.

"Sure, there is something to improve, but I don't want to talk about it right now. I'm going to talk to my coach about what I need to improve. She wasn't an easy opponent. She just won a tournament and I knew it was going to be a tough match, and a tough match it was."

Two 19-year-old qualifiers were also among Tuesday's winners, as Chinese player Wang Xinyu and Russian Kamilla Rakhimova safely went through to the last-16 stage.

Rafael Nadal has withdrawn from the Miami Open as he bids to recover full fitness in time for the European clay season.

The 20-time grand slam singles champion has not played since losing to Stefanos Tsitsipas in the quarter-finals of the Australian Open in February.

Nadal pulled out of the Rotterdam Open and turned down a wildcard for the Dubai Tennis Championships due to a persistent back problem.

The world number three, who has never won the title in Miami, wants to prioritise his recovery ahead of the beginning of the clay-court swing in April.

Writing on Twitter on Tuesday, he said: "Sad to announce that I won't be playing in Miami, a city that I love.

"I need to fully recover and get ready for the clay-court season in Europe. Special message to my fans in the US and in particular to the great Spanish-speaking community FL who always give me a great support!"

Nadal follows long-time rival Roger Federer in withdrawing from the tournament, the Swiss great choosing to focus on training after only returning to the Tour from a 14-month absence at the Qatar Open.

Federer is the reigning champion in Miami, having beaten 2018 winner John Isner in the final two years ago. The 2020 tournament was cancelled due to coronavirus concerns.

A resurgent Leroy Sane has his sights set on achieving his "huge" career goal of experiencing the Champions League glory his Bayern Munich team-mates enjoyed last season.

The winger joined Bayern from Manchester City after they had tasted European success by defeating Paris Saint-Germain in the final.

Sane had a mixed start at Bayern, in and out the line up as he worked his way back from a long-term injury that restricted him to two appearances in his final season at City.

The 25-year-old has looked like his old self of late, registering either a goal or assist in four of his last five matches, including a strike in Bayern's emphatic 4-1 away win in the last-16 first leg away to Lazio.

Bayern were four goals up after 47 minutes of that game, but ahead of Wednesday's home second leg against Lazio, Sane wants his team-mates to take nothing for granted, which would jeopardise his Champions League dream.

"[Winning the Champions League is] a huge goal of mine," said Sane.

"That is why I place so much value on delivering a good match on Wednesday and for the rest of the season.

"When we have Champions League matches, we need to always be well prepared and up for it. 

"All of us know that a lot can still happen. Just because we scored a few goals in the first leg doesn't mean that we are through. 

"Lazio have a strong team and things could backfire if we don't take it seriously.

"I'm feeling better and better, and have had time to get to know the team and how we play. We get along very well off the pitch as well. Everyone is prepared to work hard, which benefits us all.

"At first, you need to get to know the workings of a team. For me it was even harder, because I didn't have a rhythm after a long injury. 

"So I needed to find my own rhythm back at first. Now I feel a lot better and I have got to know the team better. That is one of the reasons why things have gone uphill for me lately."

Bayern are hosting Lazio for the first time in European competition.

None of the last 21 sides facing them away from home for the first time in the European Cup or Champions League have won (W20 D1) since Bordeaux triumphed 2-0 back in November 2009.

Head coach Hansi Flick hopes to have fitness doubts Manuel Neuer and Kingsley Coman available.

"Manu has a slight cold, and Kingsley is dealing with some muscle issues," he said. "We will have to wait and see, but we are hoping that both will be able to feature on Wednesday.

"We want to win this game [the second leg] as well. We're in the midst of a good run and want to continue it.

"Especially since we're at home, we really want to win to further build our self-confidence.

"We've delivered strong performances in the Champions League, as well as in the Bundesliga. Our current aim is to continue on in this manner."

Flick was not keen to discuss the Germany job, which will become vacant when Joachim Low leaves after Euro 2020, any further.

"I have said everything about this topic, but nothing has changed for me," he said. "I do not comment on the topic."

Since Flick took charge of the club, Bayern have won their six home games in the Champions League by an aggregate score of 18-3. 

However, only one of the previous six have come in the knockout stages of the competition – beating Chelsea 4-1 in the second leg of last season’s round of 16.

Lazio, meanwhile, have only won one of their last 15 away games in the Champions League (D5 L9).

The Serie A side are winless in the last eight matches of that run (D4 L4) and have not one away in the competition was back in September 2003.

Zlatan Ibrahimovic has been called up by Sweden for the World Cup qualifiers against Kosovo and Georgia, paving the way for him to play at Euro 2020 this year.

Ireland number eight CJ Stander has dropped a retirement bombshell by declaring he will quit rugby at the end of the season.

Stander said the Irish Rugby Football Union (IRFU) and his club, Munster, tried to talk him out of leaving the game.

But 30-year-old Stander, who won his 50th cap in Ireland's 27-24 win over Scotland on Sunday, could not be persuaded to make a U-turn.

The South Africa-born back-rower said: "All professional sports people are told 'you will know when the time is right to hang up your boots'.

"It’s a sentiment one cannot fully comprehend until that day arrives. For me, that time has come, and I hereby publicly announce my retirement from all forms of rugby.

"I will be available to represent Munster until 27 June 2021 when my contract expires, and for international duty, until the end of the mid-year Test window."

Stander, who came to Ireland at the age of 22, said rugby had "started to take an unfair toll on my family".

He qualified to play for Ireland by residency and made his debut in the 2016 Six Nations, going on to play for the British and Irish Lions on their tour of New Zealand a year later.

In 2018, Stander helped Ireland achieve a Six Nations Grand Slam, but now he says rugby must take a back seat.

"I asked myself whether I was still enjoying this enough to earn the continued support of Munster and Ireland, and to justify the sacrifices my family was making. From a performance perspective, the answer was yes," Stander said in a statement.

"But I always had the intent to retire while I was still playing some of my best rugby. I also knew I wanted my daughter Everli to grow up around her family in South Africa.

"When all these intentions and considerations intercepted each other during that training session, I discussed the implications thereof with [Munster] coach Johann van Graan and the Irish Rugby Football Union.

"I deeply appreciate that they tried to persuade me otherwise, but I knew it was time."
