Williams sisters reach semis of US Open doubles
NEW YORK -- Venus and Serena Williams have knocked out the top-seeded women's doubles team at the U.S. Open to advance to the semifinals.
Their victory in Armstrong Stadium finished less than an hour after Americans Bob and Mike Bryan had their quest for the calendar Grand Slam halted next door in Arthur Ashe Stadium. The Bryans fell 3-6, 6-3, 6-4 to Leander Paes and Radek Stepanek.
Serena Williams, looking for back-to-back singles titles, plays her semifinal Friday against Li Na.
