Beijing:Venus and Serena Williams have clinched at least a silver medal in doubles for the United States with a victory in the Olympic semifinals.
The sisters beat another sibling pair, Ukraine's Alona and Kateryna Bondarenko, 4-6, 6-4, 6-1 on Saturday.
The Williams sisters improved to 9-0 lifetime in Olympic doubles. They won the gold medal at Sydney in 2000 but didn't play doubles in 2004 because Serena was hurt.
Both were beaten in the quarterfinals of singles on Thursday.
