LONDON -- Maria vs. Serena.
Maria Sharapova and Serena Williams have played each other twice at Wimbledon -- once for the title in 2004 -- and will be meeting on the grass again at the legendary All England Club.
This time, it will be for an Olympic gold medal.
The two biggest stars in the women's game will play in the women's final on Saturday, requiring little effort to get past the semifinal stage Friday. Williams, seeded fourth, beat No. 1 Victoria Azarenka of Belarus, 6-1, 6-2, and No. 3 Sharapova of Russia beat countrywoman Maria Kirilenko, 6-2, 6-3.
Serena Williams won doubles gold with older sister Venus in Sydney in 2000 and in Beijing in 2008, and is seeking her first Olympic medal in singles. This latest victory extended Williams' winning streak at the All England Club to 12 matches, as she won Wimbledon last month.
