Washington Nationals short-stop Trea Turner has been pulled mid-game on Tuesday after testing positive to COVID-19.

Turner had already hit an infield single and scored on a home run in Tuesday's game against the Philadelphia Phillies.

The 28-year-old went down the tunnel after touching down on home plate and did not re-appear to take to the field at the bottom of the first inning.

The Nationals later confirmed that Turner's premature removal was due to testing positive to COVID-19.

Turner, who has hit .320/.368/.519 in 95 games this season with 124 hits and 18 home runs, has been linked with a move away from Washington ahead of Friday's MLB Trade Deadline.

Alex Ovechkin’s pursuit of the NHL’s all-time record for goals scored will continue with the only franchise he has ever played for after the Washington Capitals re-signed their captain to a five-year, $47.5 million contract on Tuesday.

Ovechkin, drafted first overall by the Capitals in 2004, is the franchise leader in games played (1,197), goals (730) and points (1,320) since making his NHL debut in 2005-06. He led the Capitals to their first Stanley Cup championship in 2018.

Ovechkin’s $124 million, 13-year contract was set to expire before NHL free agency officially begins on Wednesday.

''Alex is the face of our franchise and is committed to this organisation and this city,'' Capitals general manager Brian MacLellan said. '

"'Alex embodies what our franchise is all about, and we're thrilled that he will continue his career in the Caps uniform for the next five years.''

Ovechkin’s 730 career goals rank sixth all-time behind Wayne Gretzky (894), Gordie Howe (801), Jaromir Jagr (766), Brett Hull (741) and Marcel Dionne (731).

Now signed through the 2025-26 season, Ovechkin – who turns 36 in September – would have to average nearly 33 goals per season during the life of his new contract to surpass Gretzky

Host nation Japan remain top of the Olympic Games medal table, one gold medal clear of the United States and China, thanks to another two gold medals on Tuesday in Tokyo.

Japan now have 10 golds at the Games, five of which have come in Judo, despite home favourite Naomi Osaka crashing out to Czech world number 42 Marketa Vondrousova in the women's singles tennis.

The USA extended their gold medal count to nine, with 17-year-old Lydia Jacoby stealing the headlines courtesy of gold in the 100m breaststroke – their third in the pool so far – though they had to settle for silver in softball as they lost to table-toppers Japan.

China, who have dominated the shooting to win eight medals in nine events, picked up three more golds with success in the 10m air pistol mixed event, the 10m air rifle mixed event and the women's 10m synchronised platform - their second diving gold in Tokyo.

The Russian Olympic Committee remain fourth with seven golds after winning the day's big event, the women's team artistic gymnastics, but that was overshadowed due to American Simone Biles withdrawing due to concerns over her mental health.

The Russians surprised in the pool, too, with Evgeny Rylov claiming 100m backstroke gold that forced defending Olympic champion Ryan Murphy to settle for bronze – that result represented the USA's first backstroke defeat since the 1992 Barcelona games.

After team-mate Adam Peaty's call for a British gold surge, Tom Dean and Duncan Scott made history by winning the first British swimming one-two since 1908 in the 200m freestyle.

Dean and Scott's swimming achievements capped a positive day for Great Britain that saw them collect six medals in total to stay in fifth place.

Meanwhile, Flora Duffy made history for Bermuda with gold in the women's triathlon as the tiny Caribbean island became the smallest country to ever win Gold at the Summer Games.

Simone Biles said she had put her "mental health first" after missing out on adding a fifth Olympic gold medal to her collection following an early withdrawal from the women’s team final.

The 24-year-old gymnastics icon revealed she was “dealing with things internally” after a disappointing performance on the vault.

Biles posted the lowest score of the first rotation on Tuesday as she landed awkwardly after failing to execute an Amanar, while only completing a Yurchenko 1.5 twist.

After she subsequently withdrew, Team USA had to settle for a silver medal behind the Russian Olympic Committee while Great Britain completed the podium.

Biles admitted that she was "fighting demons", explaining: "I just don't trust myself as much as I used to. I don't know if it's age. I'm a little bit more nervous when I do gymnastics. I feel like I'm also not having as much fun."

She added: "I say, 'put mental health first'. Because if you don't, you won't enjoy sport and won't succeed as much as you want to.

"So it's okay sometimes to sit out the big competitions to focus on yourself, because it shows how strong a competitor and person that you really are, rather than just battling through it."

OSAKA STUNNED

The big names continue to tumble in the women’s singles tennis event, with second seed Naomi Osaka defeated in straight sets.

The home favourite, who lit the Olympic cauldron on Friday, was denied a place in the quarter-finals after being ousted 6-1 6-4 by world number 42 Marketa Vondrousova.

This event marked Osaka’s first competitive tennis in two months since her early withdrawal from the French Open at the end of May, citing mental health issues.

The world number two is the latest of the big names to fall at the Tokyo Games, with top seed Ash Barty and third seed Aryna Sabalenka also suffering early exits.

"Of course, it's one of the biggest wins of my career," Vondrousova said. "Naomi is a great player, so I knew it would be a tough match. 

“I'm very happy with my play. I played amazingly in the first set, and then the second set was really tough. I'm just happy to be through."

ARGENTINA RECOVER TO SEE OFF SPRINGBOKS

Argentina recovered from a dreadful start to beat South Africa and book their place in the rugby seven semi-finals.

Trailing 7-0 after just under two minutes, the Pumas were then reduced to six men when Gaston Revol - who was reduced to tears - was shown a straight red card.

Nevertheless, they demonstrated tremendous resilience and character before eventually running out 19-14 winners.

Argentina will play Fiji in the last four after the reigning Olympic champions swept Australia aside 19-0.

Great Britain stormed back from 21-0 down to beat the USA, scoring four tries to secure a dramatic 26-21 victory.

Team GB will play New Zealand, who eased to a 21-10 success over Canada.

Massimiliano Allegri revealed he turned down Real Madrid in favour of a second spell with Juventus.

Allegri was appointed as Bianconeri boss in May after Andrea Pirio was relieved of his duties following a poor season, ending with the club only fourth in Serie A.

The experienced Allegri led the Turin giants to five consecutive Serie A titles, four Coppa Italia triumphs and two Champions League finals during his previous tenure.

Allegri, 53, on Tuesday revealed he could have taken over at Madrid before Carlo Ancelotti was appointed as head coach.

"I have to thank Real Madrid and the president for the opportunity he gave me [to coach Real Madrid]. Then I thought about it and chose Juventus," Allegri said during his presentation news conference.

"It was a gesture of love for a club that gave me a lot and who I enjoy coaching."

Inter's 2020-21 Scudetto triumph ended Juventus' nine-year spell of dominance in Italian football and Juve president Andrea Agnelli is hoping Allegri can reassert the Bianconeri's authority.

"It’s useless to present him and repeat what he’s won once again. Perhaps, the streak of Serie A titles he’s won is something impossible to equal," Agnelli added at Allegri's unveiling.

"We analysed what Juventus could have been with the return of Allegri, we agreed that it could have been a risky choice for both of us because of his glorious past and the expectations that he would bring.

"What Juventus can give is the right environment to reach these results. Every victory has been achieved thanks to hard work. As Max has said many times, winning is not for everybody.

"A new season begins, our target is to be competitive for every trophy in March, then we’ll see. Max is the coach of Juventus for the next four years because he has the credibility to write an exciting new chapter."

The Juve president took a dig at former head coach Maurizio Sarri, who had claimed the 2019-20 Scudetto he won in Turin was taken for granted.

"Here at Juventus, we work hard every day to achieve victories," Agnelli continued.

"We can’t take victories for granted, whoever thinks that the trophies we’ve won over the last few years have been less appreciated is wrong because, behind every trophy and every season, there is a great commitment, sacrifice and desire to win."

Agnelli also confirmed Giorgio Chiellini, who captained Italy to their first European Championship triumph since 1968 at Euro 2020, will sign a contract extension with the club.

Federico Delbonis and Laslo Djere crashed out of the Generali Open in the first round on Tuesday.

Fifth seed Delbonis and sixth seed Djere were the highest-ranked players in action on day two, but both fell to surprise defeats.

Delbonis, a recent semi-finalist at the Hamburg European Open, was convincingly beaten 6-2 6-4 by Arthur Rinderknech.

Frenchman Rinderknech fired down 10 aces and was only broken once in the contest.

Djere, meanwhile, put up more of a fight but ultimately succumbed to Daniel Altmaier, who won 4-6 6-3 6-3 in a battle lasting two hours and 10 minutes.

World number 50 Djere had also made the semi-finals in Hamburg and followed that up with another run to the last four at the Swiss Open Gstaad.

But his run of form came to an end as German Altmaier – who himself enjoyed a semi-final run in Croatia last week – booked a last-16 tie meeting with Marco Cecchinato after breaking Djere on six occasions.

Cecchinato had beaten Radu Albot in straight sets to reach the next round while qualifier Jozef Kovalik saw off Jaume Munar with a 6-4 6-4 victory.

The top four seeds, including number one Casper Ruud, will begin their campaigns at the ATP 250 event in Kitzbuhel on Wednesday.

The second Twenty20 International of the series between Sri Lanka and India has been put back a day after Krunal Pandya tested positive for coronavirus.

Pandya was in the India team that won the first match by 38 runs in Colombo on Sunday, but the all-rounder returned a positive test ahead of the second game scheduled to take place on Tuesday.

The Board of Control for Cricket in India (BCCI) revealed eight members of the touring party were identified as close contacts with Pandya, so they have been forced into isolation.

Sri Lanka and India will instead contest the second game on Wednesday, with the third and final game of the series taking place on Thursday.

The BCCI revealed RT-PCR tests were undertaken to discover if there has been any further outbreak in the squad.

Simone Biles outlined the importance of athletes' mental health as she talked through her decision to sit out the women's team all-around final on Tuesday.

The gymnastics superstar's first final of the Tokyo Olympics attracted plenty of attention at the Ariake Gymnastics Centre, beginning a bid for a record-breaking six golds at one Games.

But the United States could only secure silver after Biles bowed out following her first routine.

Biles – the sport's premier performer – posted the lowest score of the first rotation (13.766) on the vault and immediately left the floor with a trainer.

Her absence from the remainder of the competition was confirmed by USA Gymnastics due to what the organisation said was a "medical issue".

But Biles opened up on the reasons for departure following the event, which was won by the Russian Olympic Committee.

Asked if she was injured, Biles said: "No, just my pride is hurt a little bit."

The 24-year-old added she was "fighting demons" and explained: "I just don't trust myself as much as I used to. I don't know if it's age. I'm a little bit more nervous when I do gymnastics. I feel like I'm also not having as much fun."

At a Team USA news conference, Biles offered a more positive message, following in the footsteps of Japan icon Naomi Osaka, who withdrew from a series of high-profile tennis events to preserve her welfare before representing her country in the Olympics on home soil.

"I say, 'put mental health first'," Biles said, asked if Osaka's stance was inspirational.

"Because if you don't, you won't enjoy sport and won't succeed as much as you want to.

"So it's okay sometimes to sit out the big competitions to focus on yourself, because it shows how strong a competitor and person that you really are, rather than just battling through it."

Biles would accept no credit for her team's medal, saying: "I didn't do my job, they came out and they stepped up.

"They did what they needed to do and more, last minute. This medal is all them and the coaches and it has nothing to do with me. They did it without me."

Giannis Antetokounmpo bucked the trend of exclusively high draft picks winning NBA MVP before Nikola Jokic took it to an entirely different level this past season.

As the 41st overall selection in 2014, Jokic became by far the lowest draft pick ever to win the award, surpassing Antetokoumpo and Steve Nash, who were both chosen 15th overall. Prior to Jokic and Antetokoumpo, the previous 10 MVPs were won by players picked between first overall (LeBron James, Derrick Rose) and seventh (Stephen Curry).

Jokic's MVP serves to further illustrate that big-time NBA talent can be found lower in the draft, and while most second round and undrafted players may not win any MVPs, they can still become regulars that make major contributions in the right situations.

This year's draft class has an elite first tier with the likes of Cade Cunningham, Evan Mobley and Jalen Suggs, yet it also boasts some solid depth, with potential gems lurking into the second round or later.

Here's a look at five players that could outperform pre-draft expectations:

KESSLER EDWARDS - Pepperdine

One look at Edwards' statistics during his three seasons at Pepperdine and improvement and versatility jump off the page. After averaging 10 points and 5.6 rebounds in his 2018-19 freshman season, Edwards went up to 13.8 with 7.5 boards the following year, followed by a breakout campaign with 17.2 points, 6.8 rebounds and a career-best 49.1 field-goal percentage in 2020-21. That also included an 87.6 free-throw percentage that ranked among the best in the nation.

He earned first-team all-WCC honours and was named CBI Tournament MVP after Pepperdine defeated Coastal Carolina for the title. Edwards was one of six Division I players this past season to average at least 17 points and 6.5 rebounds while also making 45 three-pointers.

Edwards proved to be consistent from deep with a 38.7 percentage (148-for-378) during his time with the Waves, and any 6ft 8" player that can score, rebound and connect from long range will draw the interest of NBA teams. Add in Edwards' length and high-level defence and a first-round pick would seem to be a guarantee, but he's expected to drop into the second round or possibly go undrafted, mainly because he didn't play at a Power Six school and the long-held belief is that facing lesser competition in college is a detriment at the next level.

One of the knocks on Edwards is a funky hitch in his shot that makes him look as if he's almost shot-putting the ball toward the basket. Maybe a team could alter his shooting style at some point but that should not prevent him from being drafted.

Even if his offensive game fails to develop - and that seems unlikely - Edwards shouldn't have a problem guarding multiple positions in the NBA. He is quick enough to stick with smaller guards and forwards and is lanky enough to cope with bigger post players as well.

 A minimal contributor off the bench would likely be where Edwards finds himself early in his NBA career, but he has enough upside as an on-ball defender with a developing perimeter game to potentially excel as a starter or regular rotation player in time.

JEREMIAH ROBINSON-EARL - Villanova

Robinson-Earl only spent two seasons at Villanova but received plenty of accolades in his brief tenure with the Wildcats. He was named Big East Freshman of the Year in 2019-20 and captured co-Big East Player of the Year honours this past season, leading the team with 15.7 points and 8.5 rebounds.

Jay Wright's program has produced a considerable amount of pro talent lately in Josh Hart, Saddiq Bey, Eric Paschall, Mikal Bridges and Donte DiVincenzo, with Robinson-Earl having an excellent opportunity to continue the Wildcats' success in the NBA.

While he does not project as a future All-Star due to average athletic ability, Robinson-Earl can do a lot of different things well and is a smart player with intangibles that NBA teams love to have on their roster. There may be other players with higher upsides that get drafted in the second round, but Robinson-Earl can score, rebound, guard multiple positions and plays with a relentless motor.

A more refined offensive game and the ability to shoot from long range more consistently would make Robinson-Earl a more appealing prospect, but he does have a soft touch and a smooth release from mid-range. He is comfortable playing low in the post, does not shy away from the physical side of the game and has great court vision with a knack for making the right play.

Much in the way that Draymond Green - a second-round pick himself - is utilised by the Warriors, Robinson-Earl could eventually fill a similar role for a team that has stars occupying other positions on the court.

JOE WIESKAMP - Iowa

Every year there are a few players that get a huge boost from the draft combine and chief among that group this season is Wieskamp. Before an impressive showing in Chicago, the Iowa sharpshooter was facing the possibility of going undrafted despite a stellar college career.

He averaged 14.8 points and 6.6 rebounds this past season and led all players in three-point accuracy, making 49.5 percent (51-for-103) of his attempts in Big Ten play in earning all-conference second team honours. Wieskamp was the only Division I player in the nation to total at least 400 points, 200 rebounds 70 three-pointers and 25 steals. He also made five three-pointers in six games in 2020-21, second most of any player from a major conference.

More than ever, teams are putting a premium on perimeter shooting and Wieskamp is among the best available in that department, as evidenced by his 41.2 percentage (184-for-447) from deep during his time at Iowa. At 6ft 7", he can use his size to take advantage of smaller defenders that get switched onto him and his mechanics are near flawless with a high release.

One knock on Wieskamp is his relative inability to create his own shot but as a good athlete with surprising jumping ability, he should be able to overcome that with experience at the next level.

Wieskamp has the skills and ability to provide instant offense off the bench and is the perfect floor spacer for today's game. His pure shooting stroke, combined with rebounding and defensive ability should make him a valuable contributor in the NBA for years to come.

JOSH CHRISTOPHER - Arizona State

Christopher is the classic story of a player whose stock drops due to an injury. Limited to just 15 games in his only season for Arizona State in 2020-21, the 6-foot 5, 215-pound guard is a high-risk, high-reward pick that has NBA athleticism with the ability to excel at both ends of the court.

A likely first-round selection before injuries and COVID protocols ended his season in February, Christopher's value took a hit, and he could fall into the middle part of the second round. That range is often the perfect time to take a gamble on an athletic player with skills that match well in the NBA, even if other parts of his game need work.

Christopher had a few exceptional games in his one college season, including a 28-point, 11-for-17 performance against then-No. 3 Villanova on November 26 in the championship game of the Empire Classic. That 28-point display was tied for the most points allowed by the Wildcats all season. Christopher ended up averaging 14.3 points, 4.7 rebounds and 1.5 steals, and while he only shot 30.5 percent (18-for-59) from 3-point range, he did connect on 12-of-27 over his final seven games.

Guards with size that can get to the basket are always in demand and that's what Christopher does best. He is quick with excellent jumping ability and doesn't have a problem finishing through contact. Whether in transition or a half-court offense, Christopher is always a threat to soar to the hoop and create space for himself and his teammates. His defence may not be NBA-ready just yet, but his quickness and athleticism should in time make him a very good on-ball defender.

It's difficult to be a starting guard in today's pro game unless the 3-point shot is a big part of your arsenal and Christopher would need to work on that aspect of his game from the start. His mid-range shot is solid, but NBA defenders are far more difficult to overcome than those in college. He will also need to improve his shot selection and decision-making but that comes with experience and maturity.

AARON HENRY - Michigan State

Henry is arguably the best defender available in this class with his 6-foot 10 wingspan, instincts and versatility. His ability at that end of the court alone could make him a valuable piece, but he has the necessary skills to contribute on the offensive end as well.

Henry was named to the All-Big Ten third team after averaging 15.4 points, 5.6 rebounds, 3.6 assists, 1.3 steals and 1.3 blocks as a junior. He was the first Michigan State player to lead a team in points, rebounds and assists since assists were first recorded in 1975.

As the focal point, Henry basically dragged the Spartans into their 23rd straight NCAA Tournament with limited help from his team-mates this past season. Henry is excellent in the mid-range and his 3-point shot is better than he gets credit for. After shooting 9-for-43 (20 percent) from long range in the first 14 game of the 2020-21 season, Henry knocked down 39.5 percent (15-for-38) over the last 14 games.

While he is unlikely to wow anyone with his physical skills and is not yet a polished offensive player, Henry is more than capable of holding his own against NBA competition. His ball-handling, passing and shot creation are very good and his mid-range output compares favorably to current NBA players Khris Middleton and Jamal Murray when they were coming out of college.

A smart and unselfish player, Henry is an excellent value pick in the second round and projects as a rotation player in the NBA.
