Stosur eases through in Dubai, Azarenka pulls out

DUBAI (Reuters) - Grand slam winners Samantha Stosur and Petra Kvitova strolled into the second round of the Dubai championships with straight sets wins on Tuesday after Australian Open champion Victoria Azarenka withdrew due to a foot injury.

Former world number one Caroline Wozniacki also went through as the leading players made short work of lower-ranked opponents on a subdued centre court.
