Kim Clijsters advanced to the Unicef Open quarter-finals with an easy 6-2 6-1 victory over Kateryna Bondarenko of Ukraine on Tuesday.

The win on grass a week ahead of Wimbledon was just Clijster’s second since returning from a three-month hip injury. She lost the opening set to Romina Oprandi on Sunday and struggled in the second before taking control of that match.

“Bondarenko’s playing style suits me a lot better,” she said.

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 a first-round match.
