Maria Sharapova, Simona Halep pull out of Brisbane International

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."

Madrid, Feb 23: Lionel Messi scored four goals and Barcelona reclaimed the top spot in the La Liga as Real Madrid suffered a surprise defeat by Levante last night, a week before the Clasico.

Madrid's nightmare afternoon was made worse by another injury to Eden Hazard, who was forced off in the second half of their 1-0 defeat in Valencia and is now doubtful to face Manchester City on Wednesday in the Champions League.

"It doesn't look good," said Real coach Zinedine Zidane afterwards.

Messi, meanwhile, ridiculed talk of a goal drought by scoring four against Eibar after four games without one, while emergency signing Martin Braithwaite made two assists off the bench, teeing up Messi and then Arthur Melo in injury-time.

Their 5-0 rout, coupled with Madrid's defeat, means Barca move back to the summit of La Liga, two points ahead of Zidane's side ahead of next Saturday's showdown at the Santiago Bernabeu.

It amounts to a considerable shift in momentum, with Barcelona away at Napoli in the first leg of the Champions League last 16 on Tuesday.

Madrid host City a day later and the plan had been for Hazard to regain form and fitness in what was only his second start since returning from three months out with a broken right foot.

But the Belgian sat in the dug-out with an ice pack around the same foot after going off and Zidane suggested it was a repeat injury after the match. "It can be weak where you've had an injury," he said.

For Madrid, playing catch-up again next weekend will be a particularly heavy psychological blow, especially given the series of off-field problems engulfing Barcelona in recent weeks.

Yet on the pitch, Messi showed no sign of distraction as the 32-year-old completed the second fastest of his now 36 league hat-tricks, after less than 40 minutes at Camp Nou.

"There's nothing left to do but stand up and applaud," Eibar wrote on Twitter afterwards.

"I won't wash my kit after hugging Messi," said Braithwaite.

Braithwaite's arrival from Leganes drew criticism after Barcelona capitalised on a curious La Liga rule that allows clubs to sign outside of the transfer window if they have lost a player to serious injury.

Brilliant Messi

Messi quickly got to work, scoring a brilliant first goal in the 14th minute after collecting the ball centrally, around 30 yards out. He had three Eibar defenders in front of him but found a way through, nutmegging Anaitz Arbilla before chipping delicately into the corner.

The second came in the 37th minute as Sergio Busquets found Arturo Vidal, who feathered a flick into Messi's path. Messi surged forward, past his stumbling opponents, and fired in.

His third, three minutes later, was the simplest of the trio and arrived only after he tried to play in Antoine Griezmann. His generosity was rewarded as a sloppy Griezmann touch meant the ball cannoned back to Messi, who apologetically poked in.

Coach Quique Setien was able to take Griezmann off with 18 minutes left and introduce Braithwaite for his debut. Braithwaite's first contribution was a skewed cross but things improved immeasurably from there, as two passes across goal gave Messi his fourth and Arthur his first.

Madrid were never in control of a chaotic contest against Levante but might have taken the lead if Hazard had done better with a long ball over the top from Marcelo, which he failed to control and then scuffed into the hands of Aitor Fernandez.

He limped off and Madrid lost their way, finally punished with 11 minutes left by a straight ball through to Morales. Luka Modric, exposed on the right side of Madrid's defence, was unable to recover and Morales caught Courtois by surprise by firing early past the goalkeeper and into the top corner.

May 5: Former Pakistan speedster Shoaib Akhtar says he is interested in becoming India's bowling coach if there is an offer, asserting that he is capable of grooming "more aggressive, fast and talkative" pacers.

Akhtar expressed his willingness in an interview on social networking app 'Helo'.

Asked if he would like to be associated with the Indian bowling unit in future, he responded in the positive. India's current bowling is Bharat Arun.

"I will definitely. My job is to spread knowledge. What I have learned is knowledge and I will spread it," Akhtar said.

One of the fastest bowlers to have played the game, he added, "I will produce more aggressive, fast and more talkative bowlers than the current ones who will tell-off the batsmen in a way that you will enjoy a lot."

He said he has always wanted to share his knowledge among budding cricketers and that he is looking to produce more aggressive bowlers.

He also added that he would like to "coach" IPL franchise Kolkata Knight Riders, for whom he has played in the cash-rich T20 league's inaugural edition.

The former pacer also spoke about his early interactions with Indian batting great Sachin Tendulkar in the 1998 series.

"I had seen him but didn't know how big a name he was in India. In Chennai, I got to know that he was known as a god in India.

"Mind you, he is a very good friend of mine. In 1998, when I bowled as fast as I could, Indian public celebrated with me. I have a big fan following in India," Akhtar said.
