STUTTGART, Germany (AP) -- Ana Ivanovic defeated Sabine Lisicki 6-1, 6-3 to send the Wimbledon finalist out in the first round of the Porsche Grand Prix on Wednesday.
Ivanovic, the world No. 12 and former French Open winner, needed just one hour to beat the 24-year-old Berliner.
Italy's Flavia Pennetta later fired 10 aces to none in her 7-5, 3-6, 6-1 win over wild card Andrea Petkovic. It left four of the six home players out of the most important German women's competition at the first hurdle.
Pennetta will face the fifth-seeded Jelena Jankovic in the second round.
Wild card Julia Goerges gave the supporters reason for cheer with a surprise 6-1, 7-5 win over Romania's Sorana Cirstea. The 94th-ranked German will next face Ivanovic on Thursday.
Italy's Sara Errani booked her quarterfinal place by defeating Kaia Kanepi of Estonia 6-3, 6-3.
No. 3 seed Petra Kvitova of the Czech Republic was playing Russia's Alisa Kleybanova later.
