Stosur moves on in Osaka, Lisicki withdraws

Osaka, Japan ( - Third-seeded Samantha Stosur cruised into the quarterfinals of the Japan Women's Open on Wednesday, while second-seeded Sabine Lisicki withdrew from the tournament.

Hercog will advance to the quarterfinals via a walkover and will meet Japanese wild card Kurumi Nara, a 7-5, 7-6 (7-4) winner Wednesday over eighth-seeded Monica Puig of Puerto Rico.
