WIMBLEDON, England -- The U.S. Olympic tennis team looks to be strong in doubles play. The roster includes sisters Serena and Venus Williams, who were chosen to extend their unbeaten streak in Olympic doubles when they seek a third gold medal in the event beginning late next month.
They will also play singles matches as well. The other women's doubles team features the top-ranked team of Liezel Huber and Lisa Raymond.
On the men's side of things, Andy Roddick and University of Georgia alumni John Isner were selected for doubles, as were brothers Bob Bryan and Mike Bryan, who won the bronze in 2008.
As expected, the U.S. roster includes first-time Olympians Ryan Harrison, Donald Young, Isner, Christina McHale and Varvara Lepchenko, an Uzbekistan native who became a U.S. citizen in September.
