WIMBLEDON, ENGLAND (AP) - Serena Williams had to earn two doubles victories with older sister Venus at Wimbledon on Wednesday, a day before her singles semifinal against Victoria Azarenka.

The Williams sisters were finally able to complete their second-round match against Maria Kirilenko and Nadia Petrova that started on Saturday but was suspended by rain. It picked up in the third set Wednesday, with the Williams sisters winning 3-6, 6-3, 9-7. They returned to the court a few hours later to beat fellow American Bethanie Mattek-Sands and Sania Mirza of India 6-4, 6-3 and move into the quarterfinals.

Serena needed her left ankle re-taped during that match but her father, Richard, said it was nothing to worry about ahead of Thursday’s semifinal. Serena is aiming for her fifth Wimbledon title in singles.
