Third-seeded Marie Bouzkova moved to the quarterfinals of the Jiangxi Open with a 7-5, 6-0 triumph over Russian Amina Anshba on Wednesday in Nanchang, China.

Anshba, ranked No. 424 in the world, challenged the Czech in the first set before dropping the decisive game on her own serve. Bouzkova powered through the second set with three service breaks.

Sara Sorribes Tormo of Spain, the eighth seed, was upset by Colombian Camila Osorio 6-4, 7-5.
