STUTTGART - US Open winner Samantha Stosur will face world number two Maria Sharapova in Friday's quarter-finals at Stuttgart's WTA tournament after beating defending champion Julia Goerges. In a repeat of last year's semi-final, Stosur, 28, was taken to three sets by Germany's Goerges in Thursday's second-round clash before the Australian dug deep for a 6-2, 2-6, 6-3 victory at the claycourt tournament.
"Mona played a lot tougher than I thought. I had watched her playing Ana and had noticed that she has a hard serve and strong strokes. But I was still surprised about how fast she could play, I virtually had no chance to defend, especially on this slippery surface, at times it left like I was playing on ice. This court contributed to Mona's game as she is very tall and can play very fast, so it was very hard for me to break her rhythm. I am sure the match between us would look very different on a hard court."
There were no such problems for French Open winner Li Na, the eighth seed, who beat Akgul Amanmuradova of Uzbekistan 6-4, 6-4 and the Chinese will play Poland's Agnieszka Radwanska in the quarter-finals. Wimbledon champion Petra Kvitova had few problems in her 6-2, 6-2 win over Italy's Francesca Schiavone to set up a last eight match against either ex-world number one Caroline Wozniacki or Germany's Angelique Kerber.
