Top-seeded Jelena Jankovic went on court twice Wednesday at the rain-disrupted Nurnberger Versicherungscup but cruised into the quarterfinals by losing only four games in three sets played.
Jankovic first completed a 6-4 6-2 win over Arantxa Rus that was suspended by darkness on Tuesday after the first set. Later in the day, she beat Johanna Larsson 6-2 6-0.
But as Jankovic cruised, the next three seeded players lost.
No.2 Klara Zakopalova was defeated 6-3 4-6 6-1 by Polona Hercog in the first round, while Galina Voskoboeva upset No.3 Alize Cornet 2-6 6-3 6-3.
Andrea Petkovic also dispatched No.4 Julia Goerges 6-1 7-5 in the second round.
Fifth-seeded Lucie Safarova, No.6 Lourdes Dominguez Lino and No.7 Simona Halep all advanced to the quarterfinals of the inaugural WTA event on grass.
