Miami 2013: Victoria Azarenka pulls out with ankle injury
Miami 2013: Second seed Victoria Azarenka pulls out of the Sony Open with an ankle injury ahead of second-round match

Victoria Azarenka has pulled out of the Sony Open in Miami with an ankle injury.
The world No3 had been due to take on Madison Keys in the second round in Miami on Friday but has been forced to withdraw. Lucky loser Lauren Davies will take the Belarusian’s place.
Double Australian Open champion Azarenka, who won the Miami tournament in 2009 and 2011, also pulled out of the Indian Wells event earlier this month with the same injury.
Meanwhile, Britain’s Laura Robson will take on 32nd seed Alize Cornet for a place in the third round in Miami on Friday after battling through her first-round match against Italy’s Camila Giorgi on Wednesday.
Elsewhere, Andy Murray has backed British No1 Heather Watson to rediscover her top form after her disappointing exit in Miami at the hands of Ayumi Morita of Japan.
Watson said she plans to stick to her schedule after initially suggesting that she would take a break because of “burn out” in the aftermath of her straight-sets defeat.
“Heather and Laura [Robson] will be fine. They have good people around them,” Murray told BBC Sport.
