Lucie Hradecka of the Czech Republic beat teenage qualifier Annika Beck of Germany 6-1, 6-1 on Wednesday to reach the quarterfinals of the Luxembourg Open.
Hradecka has never won a singles title but was runner-up in Quebec City last month. She next faces either second-seeded Julia Goerges of Germany or Romania's Monica Niculescu.
Lourdes Dominguez Lino of Spain made it into her first quarterfinals since February in Monterrey, Mexico, beating Magdalena Rybarikova of Slovakia 6-2, 6-3.
Among first-round winners were Daniela Hantuchova of Slovakia, Ksenia Pervak of Kazakhstan, Andrea Petkovic of Germany, and Anne Keothavong of Britain, who entered the draw when fourth-seeded Yanina Wickmayer of Belgium was sidelined by a knee injury.
