Saina and Sindhu might collide in Japan Open next week

New Delhi, Jul 6: India's cricket chief Sourav Ganguly says improved fitness standards and a change in culture have led to the country developing one of the world's best pace attacks.

Spearheads Mohammed Shami and Jasprit Bumrah are part of a battery of five formidable quick bowlers that have helped change India's traditional reliance on spin bowling.

"You know culture has changed in India that we can be good fast bowlers," Ganguly said in a chat hosted on the Board of Control for Cricket in India (BCCI) Twitter feed.

"Fitness regimes, fitness standards not only just among fast bowlers but also among the batters, that has changed enormously. That has made everyone understand and believe that we are fit, we are strong and we can also bowl fast like the others did."

The West Indies dominated world cricket in the 1970s and 1980s led by a fearsome pace attack that included all-time greats such as Michael Holding, Andy Roberts, Malcolm Marshall and Joel Garner.

Recently Indian quicks have risen to the top in world cricket with Shami, Bumrah, Ishant Sharma, Umesh Yadav and Bhuvneshwar Kumar in a deadly arsenal.

"The West Indies in my generation were naturally strong," the former India captain said.

"We Indians were never such naturally strong... but we worked hard to get strong. But I think it is the change in culture as well that is very important."

Shami last month claimed that the current Indian pace attack may be the best in Test history.

"You and everyone else in the world will agree to this -- that no team has ever had five fast bowlers together as a package," said Shami.

"Not just now, in the history of cricket, this might be the best fast-bowling unit in the world."

Shami took 13 wickets during India's 3-0 home Test sweep over South Africa last year, while Bumrah has claimed 68 scalps in 14 Tests since his debut.

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."
