World number one Ash Barty has been knocked out of the Charleston Open after a straight-sets loss to unseeded Spaniard Paula Badosa in Friday's quarter-finals.

Badosa won 6-4 6-3 over the favoured Australian in one hour, 16 minutes to book a spot in the last four on the green clay and a meeting with 15th seed Veronika Kudermetova.

Kudermetova beat 2017 US Open winner Sloane Stephens 6-3 6-4 in her first win over a grand slam winner.

Former French Open junior champion Badosa, who beat fifth seed Belinda Bencic in the second round, claimed her second career victory over a top-20 player against Barty.

Barty may have hit 34 to 19 winners but she also made twice as many unforced errors, 24 to 12.

The Spaniard broke Barty's serve five times while she sent down seven aces and saved 12 of 14 break points.

"I was quite nervous today but I think I served very well and I think that was the key for the match," Badosa said in her on-court interview.

"It was a tough match but I was there until the last moment and I managed to win."

World number 71 Badosa becomes the lowest-ranked player to beat Barty since September 2019.

The Australian had won eight matches in a row after last week's triumph at the Miami Open.

Unseeded Montenegrin Danka Kovinic came from a set down to topple 11th seed Yulia Putintseva 6-7 (2-7) 7-5 6-1.

Kovinic, who knocked out Petra Kvitova in the third round, will play 12th seed Ons Jabeur in the semi-finals after she overcame Coco Gauff 6-3 6-3.

Meanwhile, at the Copa Colsanitas in Bogota, fifth Tamara Zidansek beat Italy's Sara Errani 6-3 6-4 to claim a spot in the semi-finals.

Viktoriya Tomova outlasted qualifier Nuria Parrizas-Diaz 5-7 6-2 6-4 in almost two and a half hours, while Harmony Tan and local wildcard Maria Camila Osorio Serrano also won.

Defending champion Dustin Johnson, Brooks Koepka, Sergio Garcia and Rory McIlroy all missed the cut at the Masters on Friday, while Justin Rose remains in the lead.

Johnson, who won the Masters for the first time in November, shot a three-over 75 on the second day to be five over overall and miss the cut by two strokes.

World number one Johnson made three bogeys on his final four holes to miss out, having previously impressed at Augusta, with top-10 finishes in his past five appearances.

He made four birdies on the front nine but also had two bogeys and a double bogey on the fifth.

Johnson becomes the third Masters champion in the past 15 years to miss the cut.

"Six three-putts in two rounds, you just can't do that," Johnson said. "Obviously didn't drive it great but drove it good enough.

"I never was really too bad out of position, just the three-putts killed me. You take all the three-putts away, I'm one under. That was kind of the difference."

The 36-year-old was joined by four-time major winner Koepka with a similar round to miss the cut, along with 2017 Masters winner Garcia, who shot an even round of 72 to finish at four over.

Four-time major winner McIlroy (74) and two-time Masters runner-up Lee Westwood (71) also failed to make the cut, with both unable to recover after poor first days at Augusta.

At the other end of the leaderboard, Rose sits one shot clear of Will Zalatoris and Brian Harman after a second-round 72, having led by four shots on the opening day.

Rose bogeyed four of his first seven holes on Friday, before steadying with three birdies on the back nine to salvage his lead.

"I think it was just a classic day at Augusta National when you're just slightly off," Rose said.

"You can be a foot or two out on certain occasions and you end up struggling. I think maybe off the back of yesterday, it starts to feel pretty different pretty quickly. But I told myself going up the eighth hole, you're leading the Masters, your frame of reference is a little bit different to yesterday. Four ahead is something, but you're still leading so like just enjoy it and keep going."

On his Masters debut, 24-year-old Zalatoris moved up the leaderboard swiftly, aided by five birdies on his back nine, including three straight to finish his round as he carded a four-under 68.

Harman also moved into contention after three birdies on his final six holes to finish with a three-under 69.

Australian Marc Leishman and last week's Texas Open winner Jordan Spieth are tied for fourth after both enjoyed strong rounds on Friday.

Bernd Wiesberger and Tony Finau both shot 66s on Friday to storm up the leaderboard into joint sixth alongside four other players, including world number two Justin Thomas.

Brooks Koepka is unsure if he will play again before the US PGA Championship after missing the cut at the Masters on Friday.

Playing for the first time since February after undergoing knee surgery, Koepka carded rounds of 74 and 75 to miss the cut at Augusta.

After back-to-back top-10 finishes at the Masters, it marked the first time the four-time major winner had failed to reach the weekend at the tournament.

With the US PGA due to start at Kiawah Island on May 20, Koepka is unsure if that will be his next competitive event.

"It's tough to say right now. That's, what, five weeks ahead, I think? It's kind of tough to say that," he told a news conference.

"I won't miss it, I know that, but tough to say if I'll play anything before that just for how it feels, how rehab goes and everything."

He added: "I wouldn't have been playing for another month if it wasn't this week. So I'll take a nice long break after this.

"Way I look at it, I have two more days to do rehab that I probably wouldn't get if I was out here, and I'll get ready for the PGA."

Koepka, who was playing just his sixth tournament of the year, lamented his putting performance at the Masters.

"Putter was ice cold, didn't make any putts. I don't want to say the speed was off, maybe the reads a little bit. Maybe the start line. I'm not quite sure," he said.

"A lot of them felt like good putts, and they weren't even hitting the hole. I don't know. It could be any one of those things. They felt good coming off the face, but they didn't even sniff it."

Top seed Pablo Carreno Busta led a clean sweep for home players to head up an all-Spanish semi-final slate at the Andalucia Open, where teenage sensation Carlos Alcaraz made history.

Carreno Busta demolished seventh seed Soonwoo Kwon 6-4 6-0, while Casper Ruud was stunned in straight sets by wildcard Alcaraz.

The 17-year-old backed up his victory over the veteran Feliciano Lopez in style, becoming the youngest ATP Tour semi-finalist since Alexander Zverev at Hamburg in 2014 with a 6-2 6-4 win.

Albert Ramos-Vinolas will face Carreno Busta after beating Norbert Gombos 6-7 (4-7) 7-5 6-4, while Alcarez is next on the agenda for compatriot Jaume Munar, who was taken the distance by Ilya Ivashka having overcome second seed Fabio Fognini on Thursday.

Taylor Fritz continued his solid form this season with a straight sets victory over Aljaz Bedene to reach the semi-finals of Sardegna Open.

Fritz is playing as the US number one for the first time in Cagliari this week and he made light work of Bedene, prevailing 6-3 6-4 to book a showdown with third seed Lorenzo Sonego, who beat Yannick Hanfmann 3-6 7-6 (8-6) 6-3 despite being 3-5 down in the second.

Seeded second and ranked 30 in the world, Fitz improved his 2021 record to 11-5 and will look to avenge a defeat in his only other meeting with Sonego on clay, when he lost at Roland Garros last year.

Lorenzo Musetti thrilled as he saved four match points to sink top seed Dan Evans on Thursday but bowed out after another epic, losing to Serbia's Laslo Djere 6-4 4-6 6-2 in two hours and 21 minutes.

Djere, who beat sixth seen John Millman en route to the quarter-finals, will face Nikoloz Basilashvili after the battle between seeds four and five ended 7-5 4-6 6-3 in the Georgian's favour.

Justin Rose mounted a back-nine recovery to finish his second round with a two-shot lead over Jordan Spieth and Marc Leishman.

Rose shot a sublime opening round of 65 at Augusta, but relinquished his four-shot advantage on Friday before returning to the top of the leaderboard with three birdies in his space of four holes.

The Englishman was the man to catch on seven under when he signed for a level-par 72, rallying after bogeying four of the first seven holes in his second round.

Gains at the 13th, 14th and 16th holes gave Rose momentum heading into the weekend as he bids to don the green jacket for the first time.

The in-form Spieth surged into a share of second place with Australian Leishman by carding a four-under 68, with birdies proving easier to come by for the field than on the opening day.

Three-time major champion Spieth, on a high after ending a title drought stretching back to 2017 at the Texas Open last weekend, made four of his five birdies after the turn and only dropped one shot at the 12th.

Leishman also made a significant move, setting the tone by starting with three birdies in row and going on to shoot a five-under 67.

Scintillating six-under rounds of 66 from Bernd Wiesberger and Tony Finau put them just three shots adrift of Rose along with Justin Thomas, who shot a 67.

Will Zalatoris, Brian Harman and Si Woo Kim were also well poised on four under, with their rounds still in progress. Defending champion Dustin Johnson had work to do back on three over through 10.

Bryson DeChambeau responded to a poor opening round with a 67 of his own to sit at one over, while Brooks Koepka (+5) and Rory McIlroy (+6) were facing a battle to make the cut 10 and eight holes into their rounds respectively.

Lee Westwood was a couple of shots below the projected cut mark on five over midway through his round.

Radu Dragusin resolved to show he can be a future cornerstone of the Juventus defence after signing a new long-term contract.

The 19-year-old Romanian central defender had been linked with a host of clubs, including Borussia Dortmund and Newcastle United, but has committed to Juventus until the end of the 2024-25 season.

Dragusin, who is 6ft 3in tall, has been compared in his style of play to Liverpool's Virgil van Dijk and has previously highlighted the Dutchman as a player he admires.

Juventus acquired him from Romanian club Regal Sport in 2018, and this season saw Dragusin make his first-team debut in December against Dynamo Kiev in the Champions League.

His new deal was announced on the Juventus website on Friday, with the club stating: "Dragusin's journey continues with Juve. Congratulations, Radu! See you on the pitch!"

The teenager, who has also made Serie A and Coppa Italia appearances this season, posted on Instagram: "I couldn't wait to sign the new contract with the team that have always believed in me.

"I want to thank first of all my family who have always been close to me and all the people who have helped me improve every day.

"Now is the time to demonstrate and put into play the trust that the club have given me. Come on Juve."

Harshal Patel hit the winning run off the last ball after claiming a five-wicket haul as Royal Challengers Bangalore beat Mumbai Indians in a thrilling first game of the Indian Premier League.

Defending champions Mumbai collapsed from 94-1 after 11 overs to 159-9 after being put in by Virat Kohli, all-rounder Harshal taking 5-27 in Chennai on Friday and Chris Lynn top-scoring with 49.

Four wickets fell in the final over of the holders' innings at M.A. Chidambaram Stadium, with Harshal claiming his maiden five-wicket T20 haul in the first match of his second spell with RCB following his Delhi Capitals exit.

Bangalore were cruising with Kohli (33) and new signing Glenn Maxwell (39) at the crease, but it was game on when they were 122-6 in the 17th over after losing four wickets for 24 runs.

AB de Villiers looked set to see them home, but RCB were left needing two off as many balls for victory when the maverick wicketkeeper-batsman was run out for 48.

Harshal held his nerve to take a single off the final delivery from IPL debutant Marco Jansen (2-28), sealing a dramatic two-wicket win for big-spending RCB.

Five-time champions Mumbai, bidding to become the first team to win the tournament three times in a row, were ultimately made to pay for scoring only 25 runs in the last four overs of their innings.

Late Harshal burst rocks Mumbai

The holders appeared set to post a challenging total with Indians debutant Lynn and Suryakumar Yadav at the crease after Rohit Sharma was run out for 19, but they capitulated in spectacular fashion.

Powerful new recruit Lynn struck three sixes as the Australian and Suryakumar (31) put on 70 for the second wicket before they were removed by Washington Sundar and big-money signing Kyle Jamieson (1-27) respectively.

Paceman Harshal then took centre stage, trapping Ishan Kishan lbw before dismissing Krunal Pandya, Kieron Pollard and Jansen in an incredible final over that ended with Rahul Chahar being run out. 

De Villiers delivers, Harshal the hero

Maxwell put on a show along with Kohli after Sundar and Rajat Patidar fell cheaply, clearing the rope twice.

The Australia all-rounder was on his way when he ramped Jansen to Lynn at short fine leg and the South African paceman struck for a second time in the 15th over to send Shahbaz Ahmed packing.

De Villiers made it advantage RCB as 15 runs came off the 18th over from Trent Boult and although he was run out by Krunal after hitting a couple of sixes in a brilliant 27-ball knock, Harshal ensured his innings was not in vain.

David Moyes has urged West Ham to attack their dream of finishing in the Premier League top four, an achievement he feels would be his best as a manager.

West Ham are fourth in the Premier League ahead of hosting third-place Leicester City in a huge encounter on Sunday.

According to reports, Michail Antonio could miss the rest of the season and Moyes has confirmed the forward has a hamstring strain.

Declan Rice is also ruled out for West Ham, who face massive stakes in their eight-game run-in, which starts with the key clash against the Foxes.

Leicester were the last non 'big six' team to finish in the top four in 2016, ending an 11-year wait after Moyes was in charge of the previous team do it (Everton in 2005).

But Moyes thinks reaching the top four with West Ham would top that.

"I think it would be [even greater]," he said to Sky Sports.

"I'd been at Everton for three years by then so that would mean it would be a bigger achievement given we're already competing. 

"[European football] would not be something new for the club, but it would be new in the modern era of West Ham.

"I still feel the Premier League has an established order - there's a lot of teams knocking at the door to see if they can get in.

"A few of the big teams are worried about it because we see that in other situations and developments with talk of a new [breakaway] league.

"We are having a really good season at the moment, we are trying to stick with it and we are not hiding from the fact we believe we are outsiders. 

"But we also believe we have got a great opportunity so why do not we try to attack it full on?

"This time last year, we had to win games in order to stay in the Premier League so we're actually all feeling very light and not heavy.

"We'll try to take a few risks, try to go for it and see if we can win them. The aim is to try to finish around the top end.

"I think most people will not expect us to make Champions League, so I hope we can try to do something very similar to what Leicester did when they went on to win the league. 

"Nobody thought they could win it."

West Ham are winless in five home matches with Leicester (D2 L3), losing 2-1 last season.

Ahead of the game, Leicester boss Brendan Rodgers backed striker Jamie Vardy to emerge from a goalscoring slump that has seen him score just once in 17 matches.

"The team has still been winning," Rodgers said. "What's most important for Jamie is you have to continue to work, make runs and sometimes you just need that bit of luck.

"He has created a number of opportunities for us. We know his threat and he can score any time.

"Jamie has just been very unfortunate, between keepers making saves and blocks on the line and some chances that, maybe, he would have put away.

"He is always going to be there. He is such a threat, his sharpness and speed, he is such an important player for us."

West Ham are looking to record their first Premier League double over Leicester since the 1999-00 season under Harry Redknapp.

The Hammers have the second-best home record in the Premier League (28 points), while Leicester have the second-best away record so far this term (34 points). 

League leaders Manchester City are the team at the top in both categories.

Indian Premier League matches could soon be held in London, according to city mayor Sadiq Khan.

Surrey, who play at The Oval, are in initial talks with IPL and BCCI authorities in India to explore the possibility.

Khan would like to see IPL matches in London and later the rest of England after similar moves were made by the big US sports leagues – the NFL, NBA and MLB – in holding competitive matches abroad.

County cricket clubs are exploring all options to make up lost revenue caused by the coronavirus pandemic.

"Surrey are speaking to teams in India and colleagues in the BCCI and IPL," Khan said.

"The first step will be friendlies and exhibition matches. 

"We want to get them going, maybe even this year if we make progress as we are doing with the pandemic. It has to be Covid-safe, of course."

Khan is seeking re-election in London and sport is central to his vision of the city's future.

He added: "We have to bang the drum for our city, and sport is one way to do this.

"This is part of my plan to build a better London after the pandemic.

"I know Londoners are hungry to see more of the likes of Virat Kohli, Rohit Sharma and Rishabh Pant.

"With two of the world's greatest cricket grounds in Lord's and The Kia Oval, London is ideally placed to host IPL matches. 

"I know we can see our capital confirmed as the undisputed sporting capital of the world."

The 2021 edition of the IPL began on Thursday, as five-time champions the Mumbai Indians look to defend their title.

IPL matches being played outside India is not unprecedented. Last year, the whole tournament was played in the United Arab Emirates without spectators because of the pandemic.

The tournament was held in South Africa in 2009 and in the UAE for two weeks of the 2014 season, in both cases due to elections in India.

Overnight leader Justin Rose was faltering through nine holes of his second round at the Masters on Friday.

The Englishman made light of tricky scoring conditions to shoot a stunning seven-under-par 65 in round one, during which he picked up nine strokes from the eighth hole having played the first seven at two over.

But after starting bogey-birdie on Friday, Rose dropped three more shots before the turn and was at four under for the tournament midway through his second round.

Bernd Wiesberger was only one shot back having gone through 14 holes at five under for the day, while Hideki Matsuyama and Brian Harman were the same score but yet to begin round two.

Jordan Spieth was only two behind through four holes of his second round, with Marc Leishman among a cluster of players also at -2.

Tommy Fleetwood, Tony Finau and Cameron Smith were all playing the round at three under as the leaderboard bunched up early on Friday, while Justin Thomas was back at level par overall.

The likes of Jon Rahm (E), Dustin Johnson (+2) and Rory McIlroy (+4) are scheduled to tee off later on Friday.

Mike Elliott will replace James Allison as technical director in a reshuffle for Formula One constructors' champions Mercedes.

Allison has led the Silver Arrows' technical operations since early in 2017, but will step back from day-to-day management to become chief technical officer on July 1.

Elliott, who started his career with McLaren 21 years ago and also worked for Renault, will be promoted to replace Allison.

He joined Mercedes as head of aerodynamics in 2012 before being appointed as the team's technology director four years ago and will switch jobs again in another reshuffle.

Mercedes said in a statement on Friday: "The transition to the new organisation will take place across the coming months as we continue the 2021 championship battle on track and prepare for the significant challenge of the 2022 technical and sporting regulations in our development programmes back at base."

Elliott said: "It has been a great pleasure and privilege to work for James earlier in my career at Renault, and for the past four years at Mercedes. His track record in the sport speaks for itself, and he has been a fantastic team-mate and leader for me during that time.

"They are big shoes to fill and I am delighted that we will be able to call on his expertise in his new role as CTO. On a personal level, it is an amazing opportunity to become Technical Director of a team like Mercedes, and I must thank Toto [Wolff] and our company for trusting me to make the step up to this new role.

"It is an incredible privilege to be part of this team and I know that the leadership strength at every level through the company will be vital to our future success.

"I can't wait to get started and to tackle the many exciting technical challenges ahead of us in the next months and years."

The Silver Arrows have won seven consecutive constructors' titles and seven-time world champion Lewis Hamilton won the season-opening Bahrain Grand Prix last month.

Eight host countries have confirmed plans to allow fans to attend matches at Euro 2020.

Venues in Amsterdam, Baku, Bucharest, Budapest, Copenhagen, Glasgow, London and St Petersburg will allow spectators at games at different capacity levels.

Wembley Stadium, which will host three group games, a round-of-16 match and the semi-finals and final, will permit a minimum of 25 per cent stadium capacity for the early rounds and hopes for a higher number for the final three games.

Games in Amsterdam, Bucharest, Copenhagen and Glasgow have confirmed capacities of 25 per cent to 33 per cent. The first three of those cities hope to increase numbers depending on their mass testing programmes and the general state of the coronavirus pandemic.

Matches in Baku can be attended by 50 per cent of the stadium's capacity, although fans travelling into Azerbaijan will need to provide a negative COVID-19 test to enter the country.

St Petersburg also hopes for a 50 per cent capacity with the prospect of an increase, while Budapest aims for full crowds provided that strict stadium entry requirements are met.

The four remaining cities – Munich, Rome, Bilbao and Dublin – have until April 19 to provide additional information on plans for spectators.

"UEFA is pleased to announce that there will be a return of spectators to the Euro 2020 venues and wishes to express its appreciation to its member associations and the national and local authorities who are collaborating closely in ensuring the safe return of spectators to the stadium," UEFA said in a statement.

"Several of the host countries had already incorporated Euro 2020 in the rollout of their national recovery strategy.  In addition, in planning the Euro 2020 final tournament, UEFA has worked closely with the World Health Organisation to adapt the WHO COVID-19 risk assessment tool for Euro 2020."

The tournament, which was postponed last year due to the pandemic, is set to begin on June 11 with the game between Italy and Turkey in Rome.

The Western Force snatched a dramatic 16-15 victory over the Rebels on Friday as the home side failed to capitalise on their dominance at AAMI Park.

Despite enjoying 65 per cent of the possession and more than twice as many passes and carries, the Rebels were thwarted by their own lack of cutting edge against a rigid rearguard.

Force then made them pay with the only try of the contest in the 78th minute, Tim Anstee touching down after a rolling maul and Domingo Miotti adding the extras.

Matt Toomua's penalty had given the Rebels a 15-6 lead midway through the second half but a further kick that struck the upright proved a costly miss in an error-strewn contest.

Miotti also missed a kick prior to the visitors' critical try, before a last-gasp wayward drop goal attempt from Reece Hodge brought the contest to a frustrating end for the Rebels.

It was a 10th successive Super Rugby meeting between the sides decided by a single-digit margin.

And the Rebels are now just a point ahead in the Super Rugby AU standings as the battle for semi-final places hots up.
