Stuttgart, Germany (Sports Network) - The last four women's Grand Slam
champions, including world No. 1 Victoria Azarenka and Wimbledon titlist
Petra Kvitova, were all on Thursday's second-round schedule at the star-
studded $740,000 Porsche Tennis Grand Prix.
The top-seeded Australian Open titlist Azarenka was leading crowd
favorite Andrea Petkovic 6-2, 4-4 when the German star retired because of a
right ankle injury. "Petko" returned from a back-induced three-month injury
layoff just this week.
Azarenka's quarterfinal opponent on Friday will be another German, wild card
Mona Barthel, who upended seventh-seeded former Wimbledon runner-up Marion
Bartoli, of France. 6-3, 6-1.
A third-seeded Kvitova, meanwhile, drubbed last year's French Open runner-up
and 2010 Roland Garros champion Francesca Schiavone 6-2, 6-2 on the indoor red
clay at Porsche Arena.
An upset came when rising German Angelique Kerber defeated sixth-seeded former
top-ranked star and 2011 Stuttgart runner-up Caroline Wozniacki for the second
time in 12 days with a 63-minute 6-1, 6-2 decision. Kerber also surprised the
Danish star in a final in Copenhagen two weeks ago.
The former U.S. Open runner-up Wozniacki is still seeking her first title of
Kerber and Kvitova will clash here on Friday, with Kerber seeking a sixth
victory over a top-10 player this year.
Also, fifth-seeded U.S. Open champ Samantha Stosur held off German favorite
and defending Stuttgart titlist Julia Goerges 6-2, 2-6, 6-3 and eighth-seeded
French Open champ Li Na handled Uzbekistani lucky-loser Akgul Amanmuradova
6-4, 6-4. Goerges became the first German champion here in 17 years (Anke
Huber) last year by stunning the then-world No. 1 Wozniacki in the Porsche
Up next for the Australian Stosur will be second-seeded Aussie Open and
Wimbledon runner-up Maria Sharapova, while the Chinese Li will encounter
rising fourth-seeded Pole Agnieszka Radwanska. Stosur was the runner-up in
Stuttgart two years ago.
The 2012 Stuttgart winner will claim $37,000 and a new Porsche.
