Serena Williams Defeats Vera Zvonareva to Advance to 2012 Olympics Quarterfinals

Serena Williams just came one step closer to defending her 2012 Wimbledon title with...another title at Wimbledon.

Williams took down Vera Zvonareva with ease on Wednesday, winning 6-1, 6-0 to advance to the Olympic quarterfinals. The No. 13 seed never stood a chance against Williams, who hit 12 aces in a match that lasted a mere 51 minutes.

The match was played under the roof at the All England Club, where Williams has become accustomed to dominating. She fought London's gloomy weather during the Wimbledon race just a few weeks ago.

Two years ago, Williams defeated Zvonareva at Wimbledon, according to the Associated Press. This time around, the Russian stood even less of a chance of upsetting the American. Williams has been on her A-game since the moment she started playing on these grass courts last month.

She was unstoppable back then, when she set a Wimbledon record with 102 aces, and she's unstoppable now, having lost a just 10 games in the first three rounds of the Olympics, according to the AP. 

Somehow, Williams has never won a gold medal in singles at the Olympics. She's won twice in doubles, but never in singles. Given the way she's been playing this year, it looks like that could change very, very soon.

Since finishing fourth at Wimbledon in 2011, Williams has been on a tear. She was the runner-up at the 2011 U.S. Open, she finished fourth at the 2012 Australian Open, and after a stunning first-round loss at Roland Garros this year, she came back with a vengeance to win it all at the All England Club last month.

The big stage of the Olympics? No big deal. Williams owns these grass courts, where she's won five titles in her career and has finished as the runner-up another two times.

With just three more wins, Williams can add the only thing her resume is missing: an Olympic gold in singles.
