LINZ, Austria -- Anna Chakvetadze overwhelmed weak-serving Francesca Schiavone 6-0, 6-2 on Wednesday to reach the quarterfinals of the Generali Ladies.

Schiavone double-faulted 10 times and won only eight points on her serve in the opening set of the 47-minute match.

Chakvetadze, a Russian ranked No. 7, drew the top seeding after defending champion Maria Sharapova and Nadia Petrova pulled out with injuries. She will next play sixth-seeded Patty Schnyder or Alicia Molik.

Earlier, fourth-seeded Dinara Safina beat Karin Knapp 6-2, 6-2. In the first round, seventh-seeded Tatiana Golovin trailed Eleni Daniilidou of Greece 6-4, 0-1 when she retired because of an injured right knee. Golovin, who reached the final of the Zurich Open last Sunday, lost her serve three times in the first set.

Nicole Vaidisova rallied past Flavia Pennetta 4-6, 6-3, 7-6 (4). The fifth-seeded Czech had 47 unforced errors and converted three of 16 break-point chances.

"Flavia is hard to beat so I am proud that I won," said Vaidisova, who defeated the Italian at this year's U.S. Open. "I'd never played before in this arena and had troubles adapting to the circumstances."

The 14th-ranked Czech didn't score a point while serving for the match at 5-4 but wrapped up the victory in the tiebreak.

Tamira Paszek advanced, beating Anabel Medina Garrigues of Spain 6-3, 7-5. The 16-years-old Austrian plays third-seeded Marion Bartoli of France in the second round.
