Sharapova wins as Cornet pulls out

Maria Sharapova was a quick-fire winner in the Porsche Grand Prix in Stuttgart today when French opponent Alize Cornet retired just 50 minutes into their second round match.

Sharapova, seeded two, had won the first set 6-3 and taken the opening game of the second before Cornet signalled she could not continue, handing the Russian a place in the last eight.
