With the victory, Serena became the first woman in history to win the career golden slam in both singles and doubles.

Hlavackova and Hradecka went 0-for-4 on their break-point chances.

The top-seeded American duo of Liezel Huber and Lisa Raymond will take on the third-seeded Russian tandem of Maria Kirilenko and Nadia Petrova for the bronze medal.
