Iga Swiatek and Coco Gauff reached the semi-finals of the Adelaide International with contrasting victories in Thursday's play.  

Reigning French Open champion Swiatek is through to the last four of a tournament for the first time since her success at Roland Garros, having spent just over an hour on court against Danielle Collins.  

Swiatek had taken the opening set and was already 3-0 in up in the second when Collins was forced to retire due to a lower back issue.  

The fifth seed will next take on Jil Teichmann, who failed to take any of the five match points that came her way during a dramatic second set tie-break with Anastasija Sevastova, though she eventually prevailed in the decider.  

Teichmann staved off two opportunities for her opponent when serving at 4-5 in the third as she claimed three games in a row to triumph, a 6-4 6-7 (10-8) 7-5 victory coming after two hours and 57 minutes.

In the other half of the draw, Gauff had to fight hard to seal her progress, having been down a set and 4-2 to Shelby Rogers.   

The 16-year-old, who came through qualifying, rallied to triumph 2-6 6-4 6-4 and reach the semis at a WTA 500 event for the first time.  

"I didn't realise how much a role experience plays until I started playing some players who are a lot older than me and they know what to do," Gauff said, per the WTA Tour's website.   

"Even when it comes to the little mind games and all that, they know what to do in those moments. So I'm just learning and picking up a few tricks and as I go."  

Gauff, who has won all three of her matches in the main draw via a deciding set, will go up against second seed Belinda Bencic, the Swiss having swept aside Storm Sanders in straight sets. 

Luguentz Dort finds himself in illustrious company after his game-winning shot lifted the Oklahoma City Thunder to victory over the San Antonio Spurs. 

With the game tied at 99-99, Dort received the ball in the corner and successfully drained a three-pointer, sealing the win in dramatic fashion before falling to the court as he was mobbed by team-mates. 

The 21-year-old is just the third player in franchise history to hit a game-winning attempt from beyond the arc as time expired. The others? Kevin Durant (twice) and Russell Westbrook (three times).

"It felt good when it left my hand," said Dort. "I was just staring at the ball and when it dropped in, I dropped too."

Having gone undrafted in 2019, Dort joined the Thunder initially on a two-way contract. He featured in 36 games last season, averaging 6.8 points per game while shooting 29.7 per cent from deep, building a reputation for his defensive abilities. 

However, he has had a larger role on offense in his second campaign in the NBA, nearly doubling his output in terms of points per game (12.5) while improving to 31.8 per cent from three-point range. 

"Lu's changed it around, obviously, changed the narrative," Thunder team-mate Shai Gilgeous-Alexander said after the Spurs game.  

"It's just him working hard, not getting down on himself, being confident. When you work hard, confidence comes with it because you believe in yourself." 

Gilgeous-Alexander also excelled against San Antonio, setting a new career high for points as he contributed 42 to Oklahoma City's cause. 

"I just wanted to be aggressive, try to put the defense on their heels, and from there, make the right play," said Gilgeous-Alexander, who scored 21 points alone in the third period.

Dort's clinching shot lifted him to 16 points, while Al Horford also managed the same.

Dejounte Murray had 27 in a losing cause for the Spurs, who were beaten for just the fourth time in 13 games on the road this season. 

LeBron James called on the depleted Los Angeles Lakers to remain confident despite suffering a fourth straight loss, this time against an in-form Utah Jazz team who set an NBA record. 

The Jazz hit 22 three-pointers as they shot 46 per cent from deep in a resounding 114-89 triumph on Wednesday, in the process improving to 26-5 for the season.

While Utah lead the way in the Western Conference, the Lakers are suffering a dip that has coincided with the absences of key duo Anthony Davis and Dennis Schroder through injury.

James acknowledged it is a "tough stretch" for the reigning champions, though even with the poor recent run they still boast a 22-11 record.

"It's challenging for all of us, especially some of our young guys and some of our guys who haven't been in the position before where they need to do a little bit more than what they are asked to in a normal situation," James said. 

"Everyone is speaking about AD [Davis], and that's obviously a big hit, but we also haven't had Dennis down this stretch too. He's a big piece of our puzzle as well.  

"But it's always about staying confident, continuing to give my team-mates the courage and confidence out there on the floor, and make plays. 

"It's a tough stretch for us, but this won't define who we will be for the rest of the season."

As for the Jazz, they are the first team in NBA history to make 50 threes over a two-game span, having finished with a franchise-record 28 in a blowout triumph over the Charlotte Hornets.

They have now won 14 straight home games by double digits, the second-longest streak posted in the NBA, behind only the Phoenix Suns (15) in the 1989-90 season.

"They came back with the same roster, but what I noticed, more than anything, is that those guys are fully healthy," James told the media.

"Mike Conley is back to himself; you can see that with the way he's moving on the floor and it's trickled down to everyone else. They are playing some really good ball and are a really good team."

Rudy Gobert did not attempt a three but still contributed 18 points, as well as nine rebounds. Conley, meanwhile, landed four of his six attempts from beyond the arc, as well as eight rebounds and eight assists.

"It's all about getting better," Gobert said. "We did a great job sharing the ball offensively. When we defend and we share the ball, it's hard to beat us."

Jamel Herring will defend his WBO super-featherweight world title against Carl Frampton on April 3 after their long-delayed bout found a new home in Dubai.

Northern Ireland's Frampton (28 wins, two defeats) has previously won world honours at super-bantamweight and featherweight and is aiming to become only the fourth fighter in history from the UK to reign across three weight classes.

He would also be the first three-division world champion from the island of Ireland, although the 34-year-old's shot at history has been delayed several times.

Herring (22-2) and Frampton were set to face off in London this Saturday but the challenger requested a delay after the recurrence of hand problems.

A change of date means a new location in The Rotunda at Caesars Palace Bluewaters, with promoter Bob Arum telling The Athletic last week that he expected fans to be allowed in attendance. The bout would have taken place behind closed doors in the UK due to coronavirus restrictions.

Herring v Frampton was first mooted in late 2019, with the global pandemic initially halting plans before Herring suffered a scratched cornea during a disqualification victory over Jonathan Oquendo last September.

Marin Cilic made a strong start to his quest to win the Singapore Open and join the ATP Tour's rather exclusive '20 club'.

The former world number three beat Taro Daniel 7-5 6-4 on Wednesday, winning 82 per cent of his first-serve points in an encouraging performance as he attempts to win a ninth indoor Tour title.

Should Cilic lift the trophy, he would join Roger Federer (103), Rafael Nadal (86), Novak Djokovic (82), Andy Murray (46) and Juan Martin del Potro (22) as the only active male players to win at least 20 Tour-level titles.

"It is the beginning of the season and my third match of the year, so I am still feeling a little bit rusty," said Cilic. "Overall, it was a solid match. [It is] something I definitely needed for the start of the tournament."

The Croatian will face Kwon Soon-woo in the quarter-finals, while Yoshihito Nishioka and Alexander Bublik were among the others to progress.

Jannik Sinner was a surprise casualty at the Open Sud de France, the world number 34 losing in three sets to Aljaz Bedene in a match that lasted nearly two hours and 40 minutes.

Sixth seed Ugo Humbert battled past Dutch qualifier Tallon Griekspoor in a match with three tie-breaks, while second seed David Goffin went the distance to overcome wildcard Benjamin Bonzi 4-6 6-4 7-5.

The Six Nations clash between France and Scotland is set to go ahead as scheduled on Sunday after a second successive days of no new positive COVID-19 tests within Les Bleus' squad.

There were major doubts over whether the round three encounter at Stade de France could be staged following a COVID-19 outbreak in the France camp.

Captain Charles Ollivon, scrum-half Antoine Dupont and Brice Dulin were among a host of players to test positive, while head coach Fabien Galthie also contracted the virus following the win over Ireland.

The French Rugby Federation on Wednesday revealed that there have been no more positive tests and the squad were able to resume high-intensity training.

Leaders France have therefore been given the green light to try and make it three wins out of three in Paris this weekend.

A Six Nations statement said: "Further to a meeting of the Six Nations Testing Oversight Group (TOG) this morning to review the latest tests results of the French Squad, the Six Nations confirm the plans to stage the France v Scotland match as originally scheduled this coming Sunday.

"We continue to monitor the situation very closely and are in regular contact with both unions."

Les Bleus are level on nine points with Wales, who face defending champions England at the Principality Stadium on Saturday.

Ireland take on Italy in the first game of the weekend at the Stadio Olimpico in what will be a battle of sides who have lost both matches.

Johnny Sexton is still "loving every moment" of playing rugby and has no intention of announcing his retirement, despite speculation over his future.

Ireland's captain missed the narrow home defeat to France in the second round of the Six Nations having suffered a head injury during his team's opening loss to Wales. 

However, Sexton is fit to return to action as Andy Farrell's side aim to finally get off the mark in this year's tournament when they take on Italy on Saturday at the Stadio Olimpico.

The 35-year-old raised questions over his career plans when he recently suggested he "might not" be around for the 2023 Rugby World Cup, though later clarified that was a "throwaway comment".

While already contemplating what may come in the next chapter of his life, Sexton remains as committed as ever to the game he loves.

"You never tell anyone your plans because they can change, can't they?" Sexton said.

"I've some things to work towards, whether it's over the next year or two years, I don't know. I'll work towards getting into the real world and starting another life.  

"There are some parts of this game that are amazing and you love – you'd love to be part of it forever. There are other parts, though, that you just can't wait to get a million miles away from. 

"I love it at the moment, I'm loving every moment of playing and I just want to focus on this campaign.

"If I stay on next year, I will try to make the most of that, just try to make the most of whatever is left." 

Sexton is under contract until the end of the campaign but has held negotiations about an extension for 2022, which will be a year out from the next World Cup on French soil. 

Asked if a new deal was close, he replied: "Nearly, nearly. I'm waiting on Leinster to see if they want to keep me or not. They have got a few good number 10s coming through!"

Ireland lost 21-16 to Wales after playing the majority of the match a man down following the red card for Peter O’Mahoney, while they were squeezed out 15-13 by Les Bleus last time out. 

"I don't think we've lost our confidence as a group. The start of the campaign has been a million miles off what we wanted, which was two wins from two," Sexton said on morale within the squad.

"But we took a lot of confidence from the Wales game with 14 men, in terms of the chances we created. The hard part in international rugby is creating chances – we've done plenty of that, we need to now go and take the next step and finish them off.  

"I don't think this group is low on confidence, we are all looking forward to finishing this campaign on a high."

Robert Lewandowski heads a stellar list of nominees for the Laureus World Sportsman of the Year Award after a golden 12 months for Bayern Munich.

Los Angeles Lakers superstar LeBron James, Formula One world champion Lewis Hamilton and tennis great Rafael Nadal are also in contention. Joshua Cheptegei and Armand Duplantis complete the male nominees.

Poland striker Lewandowski enjoyed a memorable 2020 for the German giants, with his impeccable performances helping Bayern to a Bundesliga, DFB-Pokal and Champions League treble. 

Across the top-five European leagues, no player could match Lewandowski's 45 goals scored in all competitions from January 1 to December 31 with Cristiano Ronaldo his nearest rival on 41.

In that 12-month period, only Barcelona great Lionel Messi (115) and Juventus superstar Ronaldo (85) registered more shots on target than Lewandowski's 83, while a shot-conversion rate of 34.09 was the fifth highest among players to score at least 20.

Reflecting his all-round contribution, Lewandowski recorded 12 assists in the calendar year, with team-mate Thomas Muller leading the way on an impressive 21. 

Unsurprisingly, Lewandowski won a fifth Torjagerkanone (awarded to the Bundesliga's top scorer) overall and a third in a row thanks to 34 Bundesliga goals in 2019-20, higher than an expected goals rate of 26.9. His 15 goals in the Champions League were also a competition high.

In a stacked deck, James is included after a year that saw him win a fourth career NBA title and first with the Lakers, while he also claimed a fourth Finals MVP award.

Across six games in the Lakers' 4-2 triumph over the Miami Heat, James averaged 29.8 points, 11.8 rebounds and 8.5 assists, while he shot 59.1 per cent from the field and drained 41.7 per cent of three-point attempts.

Mercedes driver Hamilton won a seventh F1 drivers' title in 2020 to match the overall record of the legendary Michael Schumacher.

During another sensational season, the Briton reached 95 career race wins, which surpasses the previous benchmark of 91 set by Schumacher.

In a calendar year disrupted heavily by the coronavirus pandemic, Nadal still had personal reason to celebrate after winning a record-extending 13th French Open title.

His triumph at Roland Garros means he now stands alongside Roger Federer on 20 grand slams – the most achieved in the men's game.

Uganda's Cheptegei broke both 5,000 and 10,000 metres world records in 2020, while Duplantis of Sweden broke the indoor and outdoor pole vault record.

Tennis' global superstar Naomi Osaka is nominated for the Laureus World Sportswoman of the Year Award.

The Japanese was champion at the US Open in 2020, which took her career slam tally to three. She recently made that four by winning the first major of 2021 at the Australian Open.

Lyon captain Wendie Renard is in contention after helping her team to a fifth straight Women's Champions League title, while WNBA Finals MVP award winner Breanna Stewart is included after guiding the Seattle Storm to championship glory.

Cyclist Anna van der Breggen – who won both the road race and time trial at the World Championships – is up for the prize, as is skier Federica Brignone, the first Italian woman to win the overall World Cup.

Kenya's Brigid Kosgei completes the women's nominees after winning the rescheduled London Marathon by more than three minutes.

Bayern, the Lakers and Mercedes are all up for the World Team of the Year Award, as are Liverpool, who won a first English top-flight title in 30 years.

The Kansas City Chiefs make the list after winning a first Super Bowl since 1970, while Argentina's men's rugby team are nominated after earning a first ever win over three-time world champions New Zealand.

Patrick Mahomes' role in the Chiefs Super Bowl win earned him a nomination for the World Breakthrough of the Year Award, with Iga Swiatek up for the prize after winning the women's singles at the French Open aged 19, the youngest slam winner since 1990.

MotoGP world champion Joan Mir, Tour de France victor Tadej Pogacar, US Open male champion Dominic Thiem and prodigious Barcelona talent Ansu Fati complete that category.

Paul George admits he is not a fan of the NBA All-Star Game going ahead this year, despite being selected to represent the Western Conference. 

George is averaging 24.6 points and shooting an impressive 48.6 per cent from three-point range this season for the Los Angeles Clippers, a team that boasts a 23-10 record after Tuesday's win over the Washington Wizards.

His efforts have been rewarded with a place among the list of reserves for the West for the game in Atlanta on March 7. 

It will be a seventh All-Star appearance for George, yet he feels that – amid the coronavirus pandemic – the league should have considered skipping the contest in 2021, insisting: "It's not something that needs to be had". 

"I'm not a fan of it, and that's just for personal reasons," George said. 

"I'm just not a fan of it with everything going on, I think it's just smart [not to happen]. I get that we have an amazing league, I'm not discrediting that. But I think, in the middle of a pandemic, it's not something that needs to be had. 

"I got fined for spending time with a team-mate, for having a team-mate over, then we're having this All-Star Game.  

"I've got personal reasons why I disagree with the game, but I've been selected, and I'll be there to play for the fans."

George missed out on selection for last year's All-Star lineups, while his first season with the Clippers finished in disappointing fashion, the team letting slip a 3-1 series lead to lose to the Denver Nuggets in the Western Conference semi-finals. 

For the 30-year-old, however, such setbacks just fuel his desire to become even better.  

"It's just more so, me just staying grounded, me staying committed just to the process. With all the noise, everything going on, you find motivation through it," he said, referencing the reaction to the Clippers' postseason collapse in the Orlando bubble. 

"You dig deep and you would be amazed on what comes out of it. It was honestly just using everything as motivation and fuel and all of that towards this year.

"It's a good milestone to start how my season is going, but definitely not where I want it to end. Got a lot more work to do."

Ash Barty crashed out of the Adelaide International at her first hurdle after going down in straight sets to Danielle Collins.

It took only 65 minutes for American Collins to defeat the defending champion and world number one in a 6-3 6-4 triumph.

Barty, who had a bye in the first round, did have opportunities, breaking in the first game of the match and building a 4-1 lead in the second set.

But on both occasions Collins stormed back, claiming her first win in four attempts against home favourite Barty, who had beaten her in the semi-finals of last year's tournament.

Coco Gauff continued her fine run to reach a first WTA quarter-final since August 2020 with an impressive comeback win over sixth seed Petra Martic.

The American triumphed 5-7 6-3 6-4 in two hours and 12 minutes to book a clash with compatriot Shelby Rogers at the WTA 500 event.

Gauff did not relinquish serve once after losing the first set and did not even offer up a break-point chance in the decider, which she sealed with a pivotal early break secured with a passing winner.

"I go into every tournament thinking that I can win," said the 16-year-old.

"Obviously that's impossible, to have a perfect record, but I go into every tournament believing that I can win. 

"I try not to think far ahead in the match, at least I just try to focus on my next match, just because you have to get through that before you can get to the finals, and just take it one match at a time."

Second seed Belinda Bencic will face Storm Sanders in the quarter-finals after a 6-1 6-3 win over Misaki Doi.

In a match where she was not quite as dominant as the scoreline suggests, Bencic had to fend off 12 break points but was successful in saving 10 of them.

Number four seed Elise Mertens withdrew before her match with a shoulder injury, so Anastasija Sevastova beat lucky loser Christina McHale to set up a last-eight tie with Jil Teichmann.

Dallas Mavericks coach Rick Carlisle praised Luka Doncic for having "laser-like focus" after his game-winning shot sunk the Boston Celtics on Tuesday. 

Doncic hit a three-point attempt with just 0.1 seconds remaining to seal a 110-107 triumph for the Mavericks in front of a small crowd, his second successful effort from deep during a dramatic finish to proceedings.

The Celtics had tied the scores at 107-107 when Jaylen Brown made a driving layup, but there was still enough time left for the Mavs to nick it. 

For Carlisle, it was just further proof that certain players are wired differently to deal with such moments, putting Doncic in the same bracket as legendary names such as Michael Jordan, LeBron James and Kobe Bryant. 

"He's just a very unique player, a very unique person," Carlisle said.

"The wiring of people like Luka Doncic, Michael Jordan, LeBron James, Larry Bird, Kobe Bryant, guys that have this laser-like focus in these situations.  

"It's difficult to explain how their minds and their brains work." 

Doncic – who will be one of the starters for the Western Conference in the All-Star Game next month – finished with 31 points, aided by making six of his eight attempts from deep.  

He had missed a late three that would have tied the game in the defeat to the Portland Trail Blazers last time out, but this time came up with the clutch shot under pressure, something he has become accustomed to taking – and making – despite not turning 22 until Sunday.

"It felt good out of my hands, I was kind of tired just running around the whole possession. But it got in, and that's all that matters," Doncic said. 

"It's something I've been doing. Sometimes two people go to me and I have to pass it. 

"Sometimes you're going to miss it, sometimes you're going to make it."

Brown led the way for the Celtics with 29 points, while Jayson Tatum contributed 28. Both players were named to the Eastern Conference All-Star reserves list prior to the game. 

"I don't feel very much like an All-Star because we're below .500," Brown said as Boston fell to a 15-16 record for the season.  

"I think this is the most I've lost since I've been here. I'm hopeful that we'll string some games together and make a run. It's very much in our grasp to do so." 

Tiger Woods is no stranger to comebacks.

Between 2014 and 2017, when an injury-plagued Woods was barely able to compete at the highest level, let alone seriously contend for honours, there were plenty of compelling storylines in golf's major championships.

Rory McIlroy and Jordan Spieth each won two in succession to suggest a glorious new rivalry was in prospect, while the latter sensationally threw away the Masters in 2016 before producing a remarkable recovery to win the following year's Open. In addition, there were two truly memorable final-day duels, Henrik Stenson edging out Phil Mickelson to win the 2016 Open Championship and Sergio Garcia pipping Justin Rose at Augusta nine months later.

By the time Garcia finally earned major glory at the 74th attempt, it was becoming easy to view Woods' career as a top-level player in the past tense. 

Little more than a month later, the former world number one was arrested on suspicion of driving under the influence in Florida, following an unexpected reaction to prescription medicine, and a humiliating mugshot of Woods made headlines around the world.

In light of that embarrassing episode and Woods' continued back problems, it was truly incredible to see a resurgent Tiger threaten to win two majors in 2018 before he then ended a five-year victory drought at the Tour Championship.

Yet it turned out the best was still to come. And there can be no doubt that the events of April 14, 2019 at Augusta comfortably trump all of the aforementioned major narratives. If golf was good in Woods' absence, it got a whole lot better when he returned, and the world will hope he has another comeback in him after Tuesday's car accident in Los Angeles.

In winning the Masters for a fifth time, Woods not only added the most remarkable chapter to his stunning career, but he once again proved he is the one athlete who moves the needle like no other.

While the likes of Roger Federer, Serena Williams, Cristiano Ronaldo, Lionel Messi, Tom Brady, and LeBron James are all rightly recognised as masters of their respective crafts, none of those superstars can match Woods when it comes to the impact they have on their sport.

When Woods is successful, interest in golf is taken to a whole new level, for one simple reason.

As Williams herself tweeted at the time of his Masters triumph, to watch his success was to witness "greatness like no other".

It is essentially impossible to quantify whether Messi is better than Federer, or whether Serena is superior to James, given they are competing in different fields.

Yet it is hard to envisage any active sportsperson commanding more attention than a successful Woods. More than a decade after his period of outrageous dominance in golf ended, he once again reprised his role as sport's most captivating figure, one who somehow regained a majestic aura after it appeared he was a busted flush.

When he secured victory at the 2019 Masters, it felt like the whole world was watching, and doubtless they are watching now – hoping for another miracle comeback.
