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Rafael Nadal has withdrawn from the Miami Open as he bids to recover full fitness in time for the European clay season.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

Real Madrid alarmed supporters with a medical bulletin declaring Rodrygo was injured again on Tuesday - before a hacker was blamed for publishing the false information.

Brazilian forward Rodrygo recently returned from a hamstring problem and has made three appearances in March.

Just hours before Madrid's crucial Champions League clash with Atalanta on Tuesday, Madrid's website carried a statement that said: "After the tests carried out on our player Rodrygo by the Real Madrid medical services, he was diagnosed with a muscle injury affecting the tendon in the right biceps femoris."

However, that news of the injury recurrence was soon pulled down and replaced by a message stating: "We're sorry... but we have been unable to find the page you requested."

The surprising initial announcement, issued in the way Madrid typically declare injury updates, caught the eye of Spain's main sports news outlets.

There was no official clarification from Madrid on how the news came to be announced; however, Marca and AS cited club sources claiming that Madrid's Twitter account and website had been hacked.

Speaking on Monday, Zinedine Zidane enthused about Rodrygo, saying: "He's a player who has adapted well to our league. He's one for the present and the future and he's improving a lot.

"We're happy with him and we know the quality he has, especially with the ball. We have to let him continue with his normal development, but we're very happy with him."

Lionel Messi was hailed as "the magical one" after he matched Xavi's appearances record for Barcelona and marked the achievement with a double strike against Huesca.

The Argentine great played his 767th game for Barca on Monday and will set an outright record if he faces Real Sociedad on Sunday.

Former Barcelona team-mate Arturo Vidal wrote on Instagram: "One more record brother @leomessi. You are the master of football. You are the best, the extraterrestrial, the only one, the magical one."

Vidal, who left Barcelona to join Inter last September, added: "Surely you will continue to beat many more records, you are unique, an extraterrestrial hug ..."

Xavi, currently coach of Qatari champions Al Sadd, paid his own compliment on Tuesday by writing to his former team-mate: "Congratulations Leo!! It's an honor that you match this record."

The 4-1 win over Huesca moved Barcelona to within four points of stuttering leaders Atletico Madrid, who have only won two of their previous five league games.

Both of Messi's goals came from outside the penalty area, and the club captain has made a habit lately of scoring from long range.

Stats Perform data shows that 36 per cent of his LaLiga goals last season (9 of 25) and 33 per cent this term (7 of 21) have come from outside the 18-yard box.

Those are the highest percentage rates he has achieved in his Barcelona career and appear to signal a change in his approach to the game as he approaches his mid-30s.

In the 2011-12 season, when Messi scored a career-high 50 LaLiga goals in 37 games, only three of those - or six per cent - came from outside the penalty area.

Six of his seven from long range this season have come in his last nine league games.

Messi turns 34 in June and reaches the end of his contract at the end of the season, with uncertainty over whether he will stay at Camp Nou.

Whether his goals are coming from inside or outside the penalty area, crucially they continue to flow from the club's record scorer, whom Barca would be loath to see depart.

Monday night's double means he has scored over 20 goals in a LaLiga campaign for a 13th consecutive season, an unprecedented feat.

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."

James Harden made history as the Brooklyn Nets earned bragging rights against rivals the New York Knicks following their 117-112 win in the NBA on Monday.

Harden posted a triple-double of 21 points, 15 assists and 15 rebounds to fuel the in-form Nets to their fifth consecutive victory.

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

Kyrie Irving scored a game-high 34 points for the star-studded Nets, who won for the 13th time in 14 games.

A 33-point and 12-rebound double-double from All-Star Julius Randle was not enough for the Knicks in the Battle of the Boroughs.

Giannis Antetokounmpo recorded his third straight triple-double to lead the Milwaukee Bucks past the lowly Washington Wizards 133-122.

Two-time reigning MVP Antetokounmpo had 31 points, 15 rebounds and 10 assists as the Bucks extended their winning streak to four games.

Antetokounmpo became the first reigning NBA MVP with three consecutive 20-point triple-doubles since Hall of Famer Michael Jordan in 1988-89, while he is the first Bucks player with three successive triple-doubles.

Big games from Bradley Beal (37 points) and Russell Westbrook (23 points and 17 assists) were not enough to inspire the Wizards.

LeBron lifts Lakers, Curry makes history

LeBron James produced another dominant display as defending champions the Los Angeles Lakers routed the Golden State Warriors 128-97. James put up his fourth triple-double of the season – 22 points, 11 assists and 10 rebounds.

Warriors star Stephen Curry finished with 27 points, three rebounds, two assists and three steals. With his second assist of the night, Curry (4,856) surpassed Guy Rodgers (4,855) as the franchise's all-time assists leader. He also nailed a three-pointer in his 100th consecutive game, the third three-point streak of at least 100 games in NBA history. Curry holds the record with a 157-game three-point run between 2014 and 2016.

MVP candidate Nikola Jokic put up 32 points and 14 rebounds in the Denver Nuggets' 121-106 win at home to the Indiana Pacers – his 35th double-double of the season.

Luka Doncic recorded a triple-double of 25 points, 16 assists and 10 rebounds, but the Dallas Mavericks lost 109-99 to the Los Angeles Clippers. With his 34th career triple-double, Doncic moved ahead of Bob Cousy for 11th on the all-time list.

Morant and George lack efficiency

Both Ja Morant and Paul George tallied double-digit points for their respective teams, however, it was far from convincing. Morant was four-of-12 shooting for 15 points in 29 minutes as the Memphis Grizzlies went down 122-99 to the Phoenix Suns, while Clippers star George had 15 points on five-of-18 shooting.

Poetry in motion

James was at his brilliant best against the Warriors, highlighted by a driving run to the basket in the second quarter.

Knicks at 76ers

The Eastern Conference-leading Philadelphia 76ers (27-12) will put their five-game winning streak on the line when they host the Knicks (20-20) on Tuesday.
