Tennis great Serena Williams has been on her A-GAME for the 2012 London Summer Olympic Games. She crushed her world no. 1 WTA peer, Victoria Azarenka of Belarus, 6,1- 6,2 with 16 aces and 33 winners, and secured a spot in this Saturday’s final against her long-time rival, Maria Sharapova of Russia. Serena says she guarantees a medal for the US, hopefully GOLD. Should be exciting!
