Henin showed no signs of rustiness on her return

The Belgian world number one took nearly a month off after beating Svetlana Kuznetsova in New York for her seventh career grand slam title.

Fifth seed Ana Ivanovic failed to join her in the last eight, losing 6-2 1-6 6-3 to qualifier Kateryna Bondarenko.

Serb third seed Jelena Jankovic fought back to beat Shahar Peer 4-6 6-1 6-3.

Henin took just a little time to warm up, eventually making the decisive break in game seven of the first set.

She broke again at the start of the second set and completed a comfortable win in 74 minutes.

"I had a nice long rest after the US Open, and this was a very good first match back for me," said Henin.
