BEIJING — Roger Federer’s long slump continued and his bid for a first Olympic singles medal ended Thursday when he lost 6-4, 7-6 (2) to American James Blake.
So began an upset parade in the quarterfinals as Serena Williams lost to Russia’s Elena Dementieva and Venus Williams was defeated by China’s Li Na.
Upsets have long been the norm in Olympic tennis — since 1988 no top-five player has won the gold medal in men’s singles.
The fifth-seeded Dementieva, who won a silver medal in Sydney in 2000, raced to a 5-0 lead in the final set and held on to beat Serena Williams 3-6, 6-4, 6-3. The unseeded Li then delighted a partisan center-court crowd by eliminating Venus Williams 7-5, 7-5.
Blake’s semifinal opponent will be Fernando Gonzalez of Chile, who defeated Paul-Henri Mathieu of France 6-4, 6-4.
Second-seeded Rafael Nadal defeated Jurgen Melzer 6-0, 6-4 and his semifinal opponent will be No. 3 Novak Djokovic, who rallied to defeat Gael Monfils 4-6, 6-1, 6-4.
U.S. nine rebounds.
