Not leaving RCB till the time I am playing IPL: Virat Kohli

Melbourne, Jan 23: Sania Mirza's return to her first Grand Slam after a two-year break was cut short on Thursday when the former world number one was forced to retire midway through her first round match in women's doubles at the Australian Open due to a calf injury.

India's Mirza, who won six Grand Slam doubles titles, took a break from the game after the China Open in October 2017 and gave birth to her son a year later.

The 33-year-old made a winning return to the WTA Tour at this month's Hobart International with Ukrainian Nadiia Kichenok, picking up her 42nd WTA doubles title and the first since winning the women's doubles in Brisbane in 2017.

Mirza said she strained her calf muscle in her right leg during the Hobart final.

"It just got worse in the match. It was bit of a bad strain, but I had a few days off," she told reporters. "So I obviously had to try to do whatever I could to try to get on the court.

"It felt okay when I went on the court, but it was tough to move right. I just felt like I'm gonna tear it or something pretty bad."

Mirza won her first Grand Slam in mixed doubles at the Australian Open in 2009 and also bagged the women's doubles in 2016.

Mirza always believed there was tennis left in her which inspired her comeback, she told Reuters on Sunday.

She had already pulled out of the Australian Open mixed doubles, where she was to partner compatriot Rohan Bopanna.

Mirza and Kichenok were trailing the Chinese pair of Xinyun Han and Lin Zhu 6-2 1-0 on Thursday when the Indian had to call it quits due to the injury.

"As a tennis player you want to compete, it is the Grand Slam. If it's any other tournament, you would probably take a call and be like 'I don't want to risk it'," she said.

Mirza, who is married to former Pakistan cricket captain Shoaib Malik, said she would take two weeks to recover and was hoping to play at next month's Dubai championships.

"When you play a professional sport, injuries are really part of it. And it's something that you have to accept," she said. "Sometimes the timing is really not ideal, it's tough that it happened in a Grand Slam, or just before a Grand Slam."

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."

Potchefstroom, Feb 4: Yashasvi Jaiswal and Divyaansh Saxena guided India to a comfortable ten wickets win over Pakistan in the ICC U19 World Cup semifinal at Senwes Park on Tuesday and progressed to the final of the tournament.

Chasing 173, Indian openers Jaiswal and Saxena played cautiously and stitched an unbeaten partnership of 176 runs.

The duo built the highest opening partnership of the tournament's history. Jaiswal, the left-handed batsman, scored his maiden century of the tournament as he amassed unbeaten 105 runs studded with eight fours and four sixes.

Saxena scored 59* off 99 balls including six fours. India chased down the total in 35.2 overs. This is the first time in the history of the U19 World Cup that a team won a knockout match by ten wickets.

Earlier, Pakistan won the toss and elected to bat.

Opener Haider Ali and skipper Rohail Nazir's half-centuries guided the side to a respectable total of 172. Ali played a knock of 56 runs while Nazir accumulated 62 runs including six boundaries.

Pakistan did not have a good start as they lost Mohammad Hurair (4) in the second over. Fahad Munir, came to bat at number three, failed to score a single run and was departed by Ravi Bishnoi on a duck in ninth over.

Apart from Ali and Nazir, Mohammad Haris was the only batsman to score runs in double digits. He played an innings of 21 runs off 15 balls. Indian bowlers showed a spirited performance as they bowled out arch-rival in 43.1 overs.
