Fernando Alonso had surgery on a jaw fracture after a road accident while cycling but is expected to be fit for the start of the 2021 Formula One season.

There were initially doubts the two-time F1 champion would be ready to make his return to the series after a two-year absence at the season-opening Bahrain Grand Prix on March 28 following the incident in Switzerland on Thursday.

Alonso underwent an operation on his jaw and is expected to remain in hospital until Sunday at the earliest.

However, Alpine have confirmed they do not expect the injury to have any impact on their preparation for the new campaign, with pre-season testing scheduled to take place at Sakhir from March 12-14.

"Following his cycling accident yesterday Fernando Alonso was kept under observation in hospital in Switzerland," read an Alpine statement issued on Friday.

"Medics discovered a fracture in his upper jaw and conducted a successful corrective operation. The attending medical team are satisfied with his progress.

"Fernando will remain under observation in hospital for a further 48 hours.

"Looking forward, after a few days of complete rest, he will be able to progressively resume training. We expect him be fully operational to undertake preparation for the season.

"Alpine F1 Team and Fernando thank you for your wishes and will issue further updates when appropriate."

Stephen Curry believes he is experiencing one of the best moments in his career and plans to let his game do the talking as the MVP conversation heats up.

The Golden State Warriors improved to 14-12 thanks to a 111-105 victory over the Orlando Magic, with Curry contributing 10 three-pointers in a 40-point haul. He also had eight rebounds, five assists and four steals.

It extended Curry's career-best streak of making at least four three-pointers to 13 games and was the 17th time he has reached double digits for makes from beyond the arc – no player in NBA history has more than five such games.

Curry acknowledged that the Warriors' win-loss record could have a negative impact on his chances of being named MVP, but he wants to solely remain focused on prolonging his impressive form.

"The game speaks for itself – 15-16, 14-15, those two years is the exact same kind of conversation," said Curry.

"Obviously, that's an amazing accomplishment, and being in that conversation with all that we've been through in the last two or three years, that means something.

"Those narratives make themselves as you go through the season and my job is to be at the level I expect to be and usually that means you're at the top of the end of the season.

"I really try not to get distracted by that because it kind of taints the moment. If I do my job, I'll be there at the end of the season."

Asked if Curry should be in the MVP conversation, Warriors coach Steve Kerr replied: "How could he not be? He's other-worldly."

He added on Curry's latest display: "It is routine, which is the crazy part of it. You just come to expect it.

"These threes that he hits when there's nothing there offensively and he just uses his dribble to free himself up, not exactly with a ton of space just a few inches of space, then he rises up and you expect every single one of them to go in, it's kind of crazy. He's in a really good groove."

Two-time MVP Curry has scored at least 30 points in four straight games and will match the best run of his career if he extends that streak to five against the Brooklyn Nets on Saturday.

While not looking to compare parts of his career, Curry acknowledged he is experiencing one of his best stretches in the NBA.

"One hundred per cent, but it's all about what's happening now. I don't compare it to what's happened in the past," said Curry.

"I obviously know the levels I've been at and our team's been at and where we're trying to go as a team, but definitely in terms of how I'm playing – I've been saying it for a while – I feel confident and strong and in rhythm. It's a good feeling and I want to keep getting better, that's the goal."

Buoyant Scotland will go in search of back-to-back wins over Wales for the first time in 18 years and France travel to Ireland for a mouthwatering Six Nations showdown this weekend.

Scotland ended a 38-year wait for a win at Twickenham on the opening weekend with a dominant 11-6 defeat of the defending champions.

Gregor Townsend's side need to follow that up on Saturday with a victory over a Wales side that got the better of 14-man Ireland at the Principality Stadium following Peter O'Mahony's first-half red card.

France started the tournament by hammering Italy 50-10, but will face a bigger test in Dublin, while England should respond to their Calcutta Cup defeat by beating Italy at home on Saturday.

Ahead of the second round, we preview the upcoming matches with help from Opta.

ENGLAND v ITALY

FORM

The Red Rose have won each of their 21 fixtures against Italy in the Six Nations, and they are the only team yet to suffer defeat against the Azzurri in the championship.

England have hosted Italy on 10 occasions in the Six Nations, winning each of those 10 fixtures by an average margin of 31 points and scoring 5.6 tries per game.

Italy have won just twice away from home in the Six Nations (losing 50 and drawing one), with both victories coming against Scotland at Murrayfield (2007 and 2015).

ONES TO WATCH

George Ford comes into the England side, with captain Owen Farrell moving to outside centre, in one of five changes to the side, and the fly-half will be ready to make a statement after being named on the bench for the loss to Scotland.

Italy endured a torrid start to the competition, but Luca Sperandio scored a fine try. The wing had seven carries and made 52 metres. The Azzurri will need to get Sperandio flying down the flank again in London.

SCOTLAND v WALES

FORM

Scotland were superb against England and will be aiming for consecutive wins over Wales in the Six Nations for the first time since 2002-2003.

Wales had an extra man, but Ireland could consider themselves unfortunate to go down 21-16 in Cardiff. The Welsh have lost their last six Tests away from home and will be in for another huge battle at Murrayfield.

They have conceded 30 points per game in that miserable sequence of matches on their travels.

ONES TO WATCH

Captain Stuart Hogg was man of the match in a rousing performance from Scotland against Eddie Jones' men. The full-back made 112 metres and had 13 carries. He was also brilliant with the boot, kicking for 367 metres.

Louis Rees-Zammit showed why he is so highly rated in Wales' win over Ireland. He dived to finish magnificently in the corner as Wayne Pivac's side made a winning start at home last Sunday.

IRELAND v FRANCE

FORM

Flanker O'Mahony's reckless dismissal proved to be costly for Andy Farrell's Ireland side in Cardiff. They will be looking to avoid suffer back-to-back losses to Les Bleus in the Six Nations, having not endured such a fate since 2010-11.

Ireland have won five of their last seven clashes with France in the Six Nations (L2) after winning only four of their 30 previous meetings with them in the Five/Six Nations (D3 L23).

ONES TO WATCH

Antoine Dupont was the player of the opening round of the tournament. The mercurial scrum-half assisted four tries, the joint-most by any player in a Six Nations match, equalling the record set by Frederic Michalak against Italy in 2006. He also scored a try of his own in a sublime performance.

Ireland lock Tadhg Beirne made the most carries (21) of any player in the opening round. He also hit the most rucks of any player (48) and was Ireland’s joint-highest tackler (10, level with CJ Stander).

Naomi Osaka admitted it was "a bit funny" to be deemed an essential worker as the Australian Open goes on.

The year's first grand slam is set to continue without fans from Saturday as Victoria heads into a five-day lockdown amid coronavirus concerns.

Professional athletes have been deemed "essential workers", meaning the Australian Open can continue.

Osaka, who raced into the fourth round with a 6-3 6-2 victory over Ons Jabeur on Friday, said that seemed strange.

Asked how she felt about being described as an essential worker, the Japanese star told a news conference: "Well, I'm not really sure.

"That kind of seems a bit funny. But I don't know, I don't make the rules. I'm just here just trying to have fun."

Three-time grand slam champion Osaka will face Garbine Muguruza in a blockbuster fourth-round clash.

Stephen Curry delivered another dazzling display of three-point shooting as the Golden State Warriors overpowered the Orlando Magic 111-105 in the NBA.

Curry went into the contest on a career-best streak of 12 consecutive games scoring at least four three-pointers, and the two-time MVP wasted no time extending that run to 13 inside the first quarter at Chase Center on Thursday.

James Harden is the only other player in NBA history to nail four threes in 13 straight games, after putting up 40 points, draining 10 of 19 from beyond the arc.

Curry has posted at least 25 points while shooting at least 50.0 per cent from the field in each of his last eight games. According to Stats Perform, it is the longest streak by any guard since Michael Jordan did so in 11 successive games in 1995-96.

Warriors team-mate Andrew Wiggins scored 21 points in support, while Magic star Nikola Vucevic hit a 25-point, 13-rebound double-double in reply.

Serena Williams labelled Victoria's five-day lockdown "rough" as the Australian Open prepares to go behind closed doors amid the coronavirus pandemic.

Fans will not be allowed to attend Melbourne Park - where crowds have been capped at 30,000 per day - from 11:59pm (local time) on Friday until Wednesday after the Victorian government announced a new state-wide lockdown to control an outbreak of the UK COVID-19 strain.

Victorian premier Daniel Andrews made the announcement as Williams booked her spot in the fourth round of the Australian Open, where the 23-time grand slam champion overcame Anastasia Potapova 7-6 (7-5) 6-2.

"I didn't know at all until the match was over. I think it's good that I didn't know," seven-time Australian Open champion Williams told reporters when asked about the lockdown.

"It's rough. It's going to be a rough few days for I think everyone. But we'll hopefully get through it."

American superstar Williams added: "It's not ideal. It's been really fun to have the crowd back, especially here. It's been really cool.

"But, you know what, at the end of the day we have to do what's best. Hopefully it will be all right."

Williams - stuck on 23 majors since winning the 2017 Australian Open in pursuit of Margaret Court's all-time record of 24 - was pushed to the limit by Russian teenager Potapova but prevailed on Rod Laver Arena.

The 39-year-old Williams - who has played and won more matches than any other woman in the tournament's history - celebrated her 90th Australian Open victory in her 101st contest.

"It was good to get through that match," said former world number one Williams as seventh seed Aryna Sabalenka awaits in the last 16. "The first set was extremely tight. I was a little tight, but it worked out. Was able to play a little more free in the second set."

The Australian Open will continue without supporters after Victoria announced a five-day lockdown amid the coronavirus pandemic. 

This year's delayed Australian Open had started on Monday with a limited amount of fans - capped at 30,000 per day at Melbourne Park - due to COVID-19 restrictions.

The Victorian government announced a new lockdown on Friday to control an outbreak of the UK coronavirus strain, state premier Daniel Andrews said.

Victoria's new state-wide restrictions will be introduced from 11.59pm on Friday - with reigning men's champion Novak Djokovic still scheduled to close out the day - until Wednesday.

"Any number of other large and small professional sport events, they will function essentially as a workplace," Andrews told reporters. "But they will not function as an entertainment event, because there will be no crowds.

"And the workforce will be the minimum that is needed in order for that to be COVID-safe and safe in lots of other contexts."

In response, the Australian Open released a statement while tournament director Craig Tiley insisted the slam will continue.

"Tennis Australia continues to work with the government to ensure the health and safety of everyone," the Australian Open said in a statement.

"The Victorian government has announced a five day lockdown commencing at 11:59pm on Friday. Australian Open sessions today and tonight will continue as planned with COVIDSafe protocols in place.

"We are notifying ticketholders, players and staff that there will be no fans onsite at the AO for five days, commencing from Saturday 13 February.

"Full refunds will be available for anyone who has tickets for these sessions and they will be advised on how to apply as soon as possible.  

"The AO broadcast-only contingency plan will commence from Saturday 13 February until restrictions are lifted. Play will continue uninterrupted on the broadcast, albeit without spectators onsite."

The Australian Open was due to get underway in January, but the COVID-19 crisis forced the year's first slam to be pushed back until February.

The lead-in tournaments across the ATP and WTA Tours took place behind closed doors in Melbourne.

Los Angeles Dodgers recruit Trevor Bauer is eyeing MLB glory after joining the World Series champions.

The Dodgers announced the arrival of National League (NL) Cy Young award winner Bauer on a three-year deal on Thursday.

Bauer - the first Cy Young winner to enter free agency since Greg Maddux in 1992 - is reportedly due to earn $40million in 2021 and $45m in 2022. The 2021 salary would make him the highest-paid player in MLB history, a record he would break again the following year.

As Bauer prepares to form an intimidating Dodgers bullpen, including past Cy Young winners Clayton Kershaw and David Price, plus star pitcher Walker Buehler, the former Cincinnati Reds talked up his desire to win.

"I want to be a member of a winning team. I want to be a member of an organisation that values me and that I value them," Bauer - part of the Cleveland Indians team who lost the 2016 World Series - told reporters on Thursday.

"I've said it a lot this entire process – I'm looking for a partnership. I want a chance to win.

"And I don't want to be a player that signs a long-term deal and towards the end is resented, either by the fan base, by the organisation, or on my end for having my performance slip below what my contract dictates. So I wanted something with the flexibility. I wanted something that worked for me and for the organisation.

"And as far as security goes, I'm well aware of the fact that I'm very well compensated and I'm plenty secure in my life, my family's life, my kid's life down in the future. 

"It wasn't about the money for me. It's about being a part of something that's bigger than myself, being a part of an organisation that can win. I want to win a World Series. I've come in second, both in college and in the big leagues. I'm tired of it. So, I want to come in first."

Bauer led the NL in ERA (1.73), WHIP (0.795), opponents' batting average (.159), opponents' BABIP (.215), adjusted ERA-plus (276), hits per nine innings (5.1), shutouts (two) and complete games (two) in the coronavirus-shortened 2020 campaign.

He also ranked second in strikeouts (100) and strikeouts per nine innings (12.3).

In nine seasons since he broke into the majors with the Arizona Diamondbacks in 2012, Bauer is 75-64 with 1,279 strikeouts and a 3.90 ERA. His only All-Star selection came in 2018.

Bauer is the eighth reigning Cy Young award winner to change teams that subsequent offseason after taking his talents to LA, and the fourth to do so in free agency, following Catfish Hunter (1975), Mark Davis (1990), Maddux (1993), David Cone (1995), Pedro Martinez (1998), Roger Clemens (1999) and R.A. Dickey (2013).

The Dodgers are the first World Series champions to add a reigning Cy Young award winner that offseason, after the 1999 Yankees, who prised Clemens to New York and went on to win the ultimate prize that year. 

Ash Barty and partner Jennifer Brady withdrew from their doubles clash at the Australian Open amid fitness concerns over the world number one.

Barty is in the spotlight after her thigh was heavily strapped during Thursday's 6-1 7-6 (9-7) victory over fellow Australian Daria Gavrilova in the women's singles.

Australian star and 2019 French Open champion Barty was scheduled to team up with Brady for Friday's doubles contest against Elise Mertens and Aryna Sabalenka, but the duo pulled out in Melbourne.

Barty did play down the severity of the thigh issue after defeating Gavrilova, with 29th seed Ekaterina Alexandrova awaiting in the third round at Melbourne Park.

"The bandage is very big, but that's more just support so that the tape itself doesn't fall off. It's not a very subtle tape job, you often see it on a lot of the girls," Barty told a news conference on Thursday.

"The guys can hide it beneath their shorts a little bit better. Just a little bit of support. I played a lot of matches in the last 10 days after not playing for 12 months, which is natural.  It's more of an assistance than anything else."

Barty added: "It came on early Tuesday, warming up for the match. But, yeah, obviously it's not affecting the way that I can play in any way.

"It's just more giving the leg some assistance to make sure it doesn't get to a point where it's going to affect me."

Last year, Barty became the first Australian woman to reach the Australian Open semi-finals since Wendy Turnbull in 1984.

The most recent finalist from the home nation was Turnbull in 1980, while Chris O'Neil was the last champion in 1978.

Los Angeles Lakers star Anthony Davis admitted he is not prepared to take any risks with an Achilles problem that has ruled him out of the NBA champions' last two games.

The injury was revealed on Sunday after Davis produced a 30-point haul against the Detroit Pistons, and the seven-time All-Star subsequently missed a pair of midweek wins against the Oklahoma City Thunder.

Davis featured in 83 of 92 games to help the Lakers end their 10-year championship drought last season - his first in Los Angeles following a blockbuster trade from the New Orleans Pelicans.

And although Davis insisted he can play through the pain barrier, the thought of rushing back and aggravating the issue in the lead up to the NBA playoffs is something the 27-year-old is not willing to entertain.

"I think every other game... I've wanted to play in. This is just a different circumstance with it being an Achilles," Davis said, after suffering tendonosis in his right heel.

"If it was a quad or finger, anything like that, I wouldn't mind playing. But I just don't really want to play around with an Achilles.

"Today was the first day we were able to practice, get some run-in with some guys to really test it out.

"I just don't want to play a game where I still feel it and then get hurt and now I'm out for the playoffs or whatever or for multiple weeks."

The Lakers extended their winning streak to six games with Wednesday’s 114-113 overtime victory against the Thunder and sit second in the Eastern Conference at 20-6.

The defending champions host the Memphis Grizzlies at Staples Center on Friday and Davis was back on court during a specially-arranged Thursday practice session.

Although Davis was also dealing with soreness in his right calf, head coach Frank Vogel seemed upbeat about his chances of returning sooner rather than later.

"We just did some drill work, no-contact drill work, which he did all of. He seemed fine," Vogel said.

"We'll see how he feels tomorrow before making any decisions on the game."

Three weeks ago, it appeared this season was shaping up to be like each of the previous 14 for the Sacramento Kings.

A 115-96 loss to the Los Angeles Clippers on January 20 marked the sixth defeat in seven games for the Kings and dropped their record to 5-10 – third worst in the Western Conference.

A month into the season and it was already looking like Sacramento would match the Clippers' dubious record of 15 consecutive seasons without a playoff berth from 1976-77 to 1990-91 for the longest playoff drought in NBA history.

Now one-third of the way into their season, however, the Kings have pulled within a half-game of the eighth-placed Golden State Warriors in the West on the heels of a 7-2 stretch. on Friday night, they take on the Orlando Magic.

The turnaround began two nights after the blowout loss to the Clippers with a 103-94 victory over the New York Knicks. The Kings' performance that night was emblematic of how they've managed to climb back into the playoff picture, but is their formula for winning sustainable?

Against the Knicks, the Kings found themselves up 89-87 with just under four minutes remaining after New York went on an 8-0 run. Sacramento then went on a 7-0 run of their own, punctuated by a Tyrese Haliburton three-pointer with 2:35 to play to put the game away.

The Kings ended up scoring 14 of the game's final 21 points, and over the next few weeks displayed a proficiency for closing out tight games.

Prior to January 22, the Kings had the NBA's third-worst fourth-quarter point differential at minus-2.8 while ranking 23rd in fourth-quarter scoring with an average of 25.5 points. Since then, they are averaging 28.1 points over the final 12 minutes of games.

It's been in the game's final moments, however, that the Kings have really excelled. Their 10.0-scoring average in the final three minutes since January 22 is the best in the NBA.

The Kings are finding ways to grind out victories and have a league-high eight wins this season by five points or less, but this typically is not a blueprint for success in the NBA.

The Kings' 5.9-point differential in their wins is the lowest in the NBA, and no team have finished a season with a point differential of less than 6.0 in their victories since 2005-06, when the Portland Trail Blazers were at 5.6 and the Atlanta Hawks were at 5.8. Sacramento, however, do not want to be too closely linked to those teams, as Portland were a league-worst 21-61 while Atlanta were not much better at 26-56.

Winning close games rarely leads to long-term success, seeing as only one team in the last 30 years have reached the playoffs while having a point differential of less than 8.0 in their wins – the 2007-08 Cleveland Cavaliers at 7.8.

In fact, in NBA history only two teams have reached the playoffs while outscoring their opponents by fewer than 7.0 points in their wins and those instances came well before man even walked on the Moon – the 1954-55 Rochester Royals at 6.6 and the 1948-49 St Louis Bombers at 6.8.

Grinding out wins over the long haul of a full season takes its toll and it may have caught up with the Kings in their last time on the court.

In Tuesday's 119-111 loss to the Philadelphia 76ers, the Kings seemed to tire down the stretch, missing seven straight shots over a three-minute stretch in the fourth quarter as the Sixers went on a 10-0 run to turn a two-point deficit into an eight-point lead with just over four and a half minutes to play.

Sacramento were playing for the third time in four days, so they were playing on tired legs, but it's also possible fatigue was setting in because each of their previous three games went down to the wire and the minutes are piling up for their stars.

De'Aaron Fox and Buddy Hield each played the entire fourth quarter on Tuesday and have regularly been playing in crunch time.

Since January 22, the Kings have four players ranking in the top 20 in fourth-quarter minutes – Haliburton (1st, 10.7), Fox (11th, 9.9), Hield (12th, 9.7) and Harrison Barnes (18th, 9.4).

The Nets are the only other team to have more than two players ranking in the top 20 in fourth-quarter minutes in that period.

Sacramento have counted on Fox down the stretch, as his 11 field-goal attempts in late and close situations since January 22 trails only the Los Angeles Lakers' LeBron James (15) and the Phoenix Suns' Chris Paul (13) for the most in the NBA. Late and close situations here are defined as the last two minutes of the final quarter when the game is within four points.

Fox's shots, however, weren't falling on Tuesday.

Over a five-game stretch from January 30 to February 7, Fox led the league with an average of 13.2 fourth-quarter points (minimum three games) while shooting 57.8 per cent. He misfired on 10 of 13 shots, though, while scoring seven points in Tuesday’s fourth quarter.

Haliburton's fourth quarter – as well as his third quarter for that matter – was even more forgettable. His final points on Tuesday came on a three-pointer with 2:00 remaining before halftime.

It was a sub-par showing for someone who is shooting at a staggering clip when the game moves to the fourth quarter.

The 20-year-old rookie is making 60.6 per cent (40-of-66) on all fourth-quarter shots – tied for fourth in the NBA with the Milwaukee Bucks’ Giannis Antetokounmpo among the 109 players with at least 50 shot attempts in the fourth – and has been connecting at an even higher percentage from beyond the arc.

Shooting an absurd 61.5 per cent on three-pointers (24-of-39) in the fourth quarter, Haliburton is on track to become the only player seeing regular minutes to shoot at least 60 per cent from deep in the final quarter in the last 15 seasons. Since 2005-06, Kyle Korver for the 2014-15 Atlanta Hawks has the highest fourth-quarter shooting percentage on three-pointers at 57.4, among players with at least 50 3-point attempts.

Haliburton has also made seven clutch three-pointers this season to trail only James (11), the Charlotte Hornets' Devonte’ Graham (eight) and the Brooklyn Nets' Kyrie Irving (eight) for most in the league. Here, clutch is defined as the last five minutes of the fourth quarter or overtime when a game is within six points.

Considering Haliburton is knocking down 44.1 per cent of his shots in the game's first three quarters, his fourth-quarter shooting has been especially baffling. His increase in shooting of 16.5 per cent from the first three quarters to the fourth is the biggest in the NBA this season (minimum 125 field goal attempts in first three quarters and 50 in fourth).

His shooting has been exceptional but hitting a rookie wall could be a concern. Tuesday marked the 22nd game of the season for Haliburton – the exact same number of games he played all of last season collegiately at Iowa State.

The fourth-quarter exploits of Haliburton and Fox have played a big role in Sacramento's climb in the standings, but the climb is just beginning. The season is only a little more than seven weeks old and time will tell if the Kings have the strength to continue their playoff push.

The Los Angeles Dodgers confirmed the signing of free agent Trevor Bauer on a three-year deal on Thursday.

Bauer, who was the National League Cy Young award winner with the Cincinnati Reds in 2020, confirmed last week he was joining the Dodgers instead of the New York Mets.

The 30-year-old pitcher will reportedly earn a record-breaking $40million in his first season with the World Series champions in 2021.

Bauer is set to then break that record again in 2022 as he earns $45m, although there are opt-out clauses after both years. It is said he will then take in $17m in the final year of his contract.

The ex-UCLA ace, who was presented at Dodger Stadium, is the first Cy Young winner to enter free agency since Greg Maddux in 1992.

Bauer led the NL in ERA (1.73), WHIP (0.795), opponents' batting average (.159), opponents' BABIP (.215), adjusted ERA-plus (276), hits per nine innings (5.1), shutouts (two) and complete games (two) in the coronavirus-shortened 2020 campaign.

The 2018 All-Star also ranked second in strikeouts (100) and strikeouts per nine innings (12.3).
