DEN BOSCH, Netherlands (AP) - Kim Clijsters advanced to the Unicef Open quarterfinals with a 6-2, 6-1 victory over Kateryna Bondarenko of Ukraine on Tuesday.

The grass-court win a week before Wimbledon is Clijsters' second since returning from a three-month absence because of a hip injury. She rallied past Romina Oprandi on Sunday.

This time, Clijsters played more aggressively and saved the only break point she faced.

Among the men, top-seeded David Ferrer of Spain beat Pierre-Ludovic Duclos of Canada 6-4, 6-4 in the first round.
