Serena Williams, ranked fourth in Women's Singles, continued to dominate on Wednesday as she easily surpassed Vera Zvonareva (13) in two straight sets 6-1, 6-0 to become the first tennis player, in both Men's and Women's tennis to advance to the quarterfinals.
Williams will now wait for an opponent to surface.
She will either face Daniela Hantuchova of Slovakia or Caroline Wozniack of Denmark.
Wozniacki is ranked eighth in the tournament. Meanwhile, unranked Daniela Hantuchova will try to advance to the 2012 Olympic Women's Quarterfinal. Their match is set to take place at 11 a.m. ET/4 p.m. GMT.
In the 2008 Beijing Games, Serena made it as far as the quarterfinals, but had her dreams of Olympic gold axed by Elena Dementieva. Williams lost that match 6-3, 4-6, 3-6.
That year was the only singles Olympic event Williams ever participated in her 15 years as a professional tennis player.
She has won gold in the past, but never in the Women's Singles. However, Williams is attempting to put an end to that bid as her strong 2012 Olympic performance demonstrates that the player wants that gold medal.
Quick prediction, hopefully it does not turn into a jynx, but both Serena and Venus Wiliams could meet in the Semifinals. Serena has to win her next match and Venus has to win two matches as she is set to hit the court later in the day. Venus is set to take on German and sevent ranked Angelique Kerber.
