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).

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.

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.

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."

Stephen Curry said it was "embarrassing" for the Golden State Warriors to crumble so woefully to the Los Angeles Lakers on the night he made franchise history.

A 128-97 loss came a day after the Warriors beat the Utah Jazz, with Curry, now the team's all-time assists leader, disheartened to be part of such a feeble showing.

For the Warriors it was another 20-plus point defeat, having suffered such losses to the Clippers and the Suns already in March.

Curry said: "We've got to play better. We have to develop a winning attitude every single night, and honestly, we've got to get sick of getting blown out, because that's embarrassing.

"We have to have some pride about how we're playing. You can lose games - that's going to happen - but not like that."

Curry added: "Winning is hard in this league. We all know that, and we all know you can't just show up, and momentum's not just going to carry just because you played well the game before.

"We talk about the margins and where we are as a team. If you want to beat the good teams, you can't have any cracks in the armour."

Curry scored a team-high 27 points and went past Guy Rodgers to become the player with the most assists in regular-season play for the Warriors, reaching 4,856 for his career with the team.

He had only two assists against the Lakers but has a career average of 6.6 per game, alongside a points average of 23.8.

"It's special. It's kind of a longevity award," Curry said of his new assists mark.

"But in terms of playing for the same franchise for 12 years and hopefully a lot longer, there's been some greats that have come through here for however long.

"And anytime you've done something or reached a level that is the top of the list for a franchise, it's pretty special. I wish it was under different circumstances obviously, with the game tonight.

"But I can take a second and appreciate that for sure, because a lot goes into that. I've had a lot of great team-mates over the years.

"Obviously I love to score, but the ability to set other guys up and assists only count if other people make baskets, so it makes it a pretty special record."

LeBron James said he takes pride in having a "triple-threat game" after closing on a landmark 100th career triple-double in the Los Angeles Lakers' rout of the Golden State Warriors.

The four-time MVP posted 22 points, 11 assists and 10 rebounds to help the Lakers to a 128-97 victory at the Chase Center on Monday, ending a two-game losing streak on the road.

It was the 98th time James had posted a triple-double in his legendary career and he spoke about what it meant to have so many weapons in his arsenal.

"For me, I've always wanted to have a triple-threat game," he told reporters.

"One where I can pass the ball. I love passing ball to my team-mates, giving those guys good looks.

"Being able to rebound, that's always important, rebounding wins championships as the great Pat Riley would say.

"And then being able to score a little bit too, that's probably the least out of the three for me, but being able to be out on the court and control the game in three facets of the game - it's always been important for me to do it in a win, the losses never mean much to me.

"To do it in a win and make an impact on the game, when it happens in the flow of a game that's what's more important."

James' performance was particularly important given the Lakers have been hit by injuries. Marc Gasol, Kostas Antetokounmpo (both health and safety protocols), Anthony Davis (strained right calf), Jared Dudley (torn MCL in right knee) and Alex Caruso (concussion protocol) were all unavailable for the defending champions.

Davis has been missing for a month but has been a vocal presence on the sidelines for the Lakers.

"I just think he's trying to lead any way possible, obviously he can't be on the floor and do things he does at a high level," James said of his team-mate.

"He's just giving his words to a lot of guys, being there for them, showing them things on the iPad, showing them films during course of a game, being as helpful as he can be to our ball team."

Alexander Zverev cruised into the second round of the Mexican Open as debutant Sebastian Korda enjoyed a memorable debut in Acapulco.

German star and second seed Zverev accounted for teenager Carlos Alcaraz, the 2019 runner-up winning the opening-round clash 6-3 6-1 on Monday.

Alcaraz – in his first showdown against a top-10 player – broke for a 2-0 lead and while he continued to go toe-to-toe with Zverev through six games, the 17-year-old was unable to maintain his charge.

Zverev broke for a 4-3 lead and the 2020 US Open finalist did not look back, winning nine of the last 10 games to advance in 84 minutes.

"He started off playing extremely well, he didn't miss a lot of balls. Then I felt more comfortable on court, this is the first round," Zverev said.

"It's not always easy to play a first round, especially against a player like this, who is very young, who is very motivated and who wants to compete. I'm actually quite happy with how the match went."

Next up for Zverev – who reached the Australian Open quarter-finals in February – is Serbia's Laslo Djere.

Djere took down Steve Johnson 6-2 6-3 for a spot in the last 16.

Meanwhile, Korda capped his Acapulco bow with a shock 7-5 6-2 win against former world number three Marin Cilic.

Korda claimed his first ATP 500-level victory having saved 10 of the 11 break points he faced in the opening set against the 2014 US Open champion.

Canadian sensation and seventh seed Felix Auger-Aliassime awaits after the 20-year-old converted his sixth match point to see off Tennys Sandgren 6-3 7-6 (10-8).

Elsewhere, John Isner and Dominik Koepfer also advanced.

Milwaukee Bucks star and two-time reigning NBA MVP Giannis Antetokounmpo said he is not Los Angeles Lakers great Kobe Bryant after making history with a third consecutive triple-double.

Antetokounmpo led the Bucks to their fourth consecutive victory on Monday, Milwaukee topping the lowly Washington Wizards 133-122.

He had 31 points, 15 rebounds and 10 assists in a dominant display on the road in Washington to become the first Bucks player with three successive triple-doubles.

Antetokounmpo also became the first reigning MVP with three consecutive 20-point triple-doubles since Hall of Famer Michael Jordan in 1988-89, per Stats Perform.

"I don't do that, I'm not Kobe," Antetokounmpo told reporters after being asked when he knew to take control of a game during the closing stages – the Bucks saw a 26-point lead cut to seven in the final minutes before Antetokounmpo scored the next four points to stop the rallying Wizards.

"I just try to be a basketball player. I don't look at the clock and say, 'Oh now we are up two or we're down two, let me take over the game.'

"No, I just make the right decision at the right moment. Sometimes it's going to be score, sometimes it's going to be pass."

Since 1983, only three players have had more games with 31 points, 15 rebounds and 10 assists – Russell Westbrook (five), Larry Bird (five) and Luka Doncic (four).

Antetokounmpo (seven) also surpassed Kareem Abdul-Jabbar (six) with the most 30-point triple-doubles in franchise history.

Bucks head coach Mike Budenholzer added: "He's been in a good place mentally.

"The way he's playing and creating for others and creating for himself and getting to the free throw line, he's in a good place. He's playing great basketball."

James Harden revelled in his history-making triple-double as the star-studded Brooklyn Nets stayed hot in the NBA.

Harden posted a triple-double of 21 points, 15 assists and 15 rebounds to fuel the in-form Nets to their fifth consecutive victory – a 117-112 win over rivals the New York Knicks on Monday.

Former MVP Harden became the first Nets player in franchise history to have a 15-plus point, 15-plus assist and 15-plus assist game.

Nets superstar Harden is averaging 25.0 points, 11.1 assists and 8.1 rebounds per game this season.

After the Nets (27-13) recorded their 13th win in 14 games, Harden was asked about triple-doubles and he told reporters "Whatever it takes. Like rebounding, I try to go help it, especially when we're small.

"I know I have to go rebound the basketball a little bit more. I know I have to put my body on bigs a little bit more because I'm not athletic enough or big enough to be able to jump with them. I've got to use my body just being crafty around that rim as far as rebounding.

"And then playmaking, it's just getting my team-mates shots and getting our bigs easy opportunities at the rim. Offensively, I'm not being as efficient as I want to be, but that's come and that's the least of my worries, the least of my concerns.

"I'm just excited and happy to continue this journey with these guys. We're playing some pretty good basketball right now."

Nets team-mate Kyrie Irving had a game-high 34 points as Brooklyn won the Battle of the Boroughs against the Knicks.

"As a kid, obviously New Jersey versus New York, that was a big thing," Irving added. "Whether the Knicks were at Continental Airlines Arena, or New Jersey was at MSG, now that Brooklyn versus New York, kind of the whole entire area, a lot of people I see on Instagram and Twitter, media outlets, just New York, New York versus this whole big thing.

"But I think as players we feel it naturally. But obviously, being from here, it's a little bit of have a different sentiment, because I got to go home and actually be around Knicks and Nets fans. It's my family. So it's basketball, it's competition. It's a world sport. So it's just nothing but respect. But obviously you want to come out here and just have fun going against New York Knicks. They've been playing well season so well, Coach, team, and just appreciate the opportunity."
