Saina enters French Open semi-final

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."

Jan 10: Australian cricketer Shane Warne’s prized 'baggy green' cap raised more than A$1 million ($686,000) on Friday for bushfire relief efforts after the former leg-spinner donated it for auction.

Twenty-seven people have been killed and thousands made homeless in recent months as huge fires scorched through more than 25.5 million acres of land, an area the size of South Korea.

The baggy green is presented to Australian players when they make their Test debut and they receive just one for their entire career. The Aussie cricketer donated the cap to an online auction site on Monday. The auction closed at 10 a.m. on Friday (2300 GMT Thursday) with a final public bid of A$1,007,500.

"Unbelievable … so generous from everyone. Totally blown away," Warne said on Twitter shortly before the auction closed.

The auction attracted global interest and the price eclipsed the A$425,000 achieved by the late Don Bradman's baggy green when it was sold in 2003.

"We have been overwhelmed and it is a fantastic result," Marc Cheah, head of marketing for auctioneers Pickles, said.

"Other baggy greens have been auctioned and Don Bradman’s got $425,000 about 15 years ago, but the Don is the Don. He’s the greatest cricketer that ever lived," Cheah said in relation to the widely held recognition Bradman was the best batsman the game has produced.

"But Shane is also right up there and that drove a lot of traffic and momentum, while the cause is also very worthwhile."

Warne, 50, is one of many local and international athletes to support the fundraising for bushfire victims with several cricketers promising to donate a sum based on the number of sixes they hit in Australia’s Big Bash Twenty20 competition.
