Sania Mirza sole world No 1 in women's doubles rankings after Cincinnati title

Zadar (Croatia), Jun 22: Grigor Dimitrov took to Instagram to announce that he has tested positive for coronavirus. The tennis star was one of the players who took part in the Adria Tour with the likes Novak Djokovic, Alexander Zverev and Dominic Thiem among others.

Taking to Instagram, the player wrote: "Hi Everyone-I want to reach out and let my fans and friends know that I tested positive back in Monaco for Covid-19. I want to make sure anyone who has been in contact with me during these past days gets tested and takes the necessary precautions. I am so sorry for any harm I might have caused. I am back home now and recovering. Thanks for your support and please stay safe and healthy."

He also urged those who had come in contact with him over the last few days in Monaco should also get tested for the deadly virus.

Meanwhile, World no.1 Djokovic reached the final of his exhibition tournament in Zadar, Croatia, after easing through the round-robin group stage on the first day. This is the second stage of the Adria Tour with Austrian Dominic Thiem winning the first leg in Belgrade, Serbia.

Djokovic started by saving three set points in his 4-3, 4-1 win over fellow Serb Pedja Krstin. He then beat home favourite Borna Coric 4-1, 4-3 in front of several thousand fans at the Visnjik tennis complex.

The tournament in Zadar is being played on red clay over two days. In the other group, Russian Andrey Rublev is in pole position to advance into the final after wins over 2014 US Open champion Marin Cilic and Serb Danilo Petrovic. He faces German star Alexander Zverev in the final round robin match on Sunday who stayed in contention after beating Cilic 4-3, 0-4, 4-3.

Djokovic''s own inconsequential final group match is against Croatian Dino Serdarusic who replaced Grigor Dimitrov after the Bulgarian pulled out of the tournament with sickness following his opening 4-1, 4-1 loss to Coric.

Melbourne, May 1: Reclaiming the top spot in Test cricket has brought smiles back on their faces but Australia coach Justin Langer says beating India in their own den remains the ultimate test and their numero uno status will be put to test when they clash with the Virat Kohli-led team.

After a tumultuous transition phase post the ball-tampering scandal, Australia on Friday displaced India as number one side in Test format but Langer is aware that it does not take long for the situation to change.

"We recognise how fluid these rankings are, but at this time it was certainly nice to put a smile on our faces," Langer told Cricket Australia website. "We've got lots of work to do to get to be the team that we want to be, but hopefully over the last couple of years not only have we performed well on the field, but also off the field," Langer added.

The former left-handed opener underlined what he felt will be the ultimate test of character.

"Certainly a goal for us has been the World Test Championship ... but ultimately, we have to beat India in India and we've got to beat them when they come back (to Australia).

"You can only judge yourself as being the best if you beat the best and we've got some really tough opposition to come," Langer put his priorities in place. The team he insists needs to get better as now others will come gunning for them.

"Getting to No.1 is a great thing, but when you're No.1, you're always the hunted," Langer said. "We've been the hunters for a while, now we're the hunted and we need to get better and better."

Langer also hoped that white ball team under Aaron Finch will win the World Cup. "I know how hard it is to win World Cups ... everything has to go right. One day, I'd love to see Aaron Finch with all his mates lift that T20 World Cup above his head."

Jul 2: Cricket Australia has decided to not use the Dukes ball from this summer's Sheffield Shield, having used it alongside Kookaburra for four seasons.

CA has confirmed that the Kookaburra ball will be used for the entire 2020-21 first-class season.

Australia has been using Dukes ball since the 2016-17 season in Shield matches with an aim to help its cricketers prepare for the hostile English conditions.

CA's Head of Cricket Operations, Peter Roach, said the decision to axe the Dukes was the right call. "The introduction of the Dukes ball has been a worthwhile exercise, particularly in the lead up to overseas Ashes series where the Dukes is used so well by our English opponents," Roach said.

"We have been happy with how the ball has performed when used in Australian conditions over the past four seasons. We do, however, feel that reverting to one ball for 2020-21 will provide the consistent examination of our players over a full season that CA and the states are presently seeking. The Kookaburra is the ball used for international cricket in Australia and many parts of the world and we see benefits this season of maximising our use of it," he added.

Roach said the ineffectiveness of spinners in first-class cricket in recent times played a role in CA's decision to do away with the Dukes. "We have noted that spin bowlers in the Sheffield Shield have been playing less of a role in recent seasons, most notably in games when the Dukes ball is in use. We need spinners bowling in first-class cricket and we need our batters facing spin. We hope that the change to one ball will have a positive benefit here," he said.

The CA official, however, didn't rule out the possibility of re-introducing it later.

"We see a definite opportunity to reintroduce the Dukes ball at some stage in the future."
