An upset-filled first week at the 2013 Wimbledon Championships is winding down as Saturday marks the conclusion of the first three rounds of play at the All England Club.
But while a plethora of female contenders have been wiped out, including Victoria Azarenka and Maria Sharapova, a pair of past women's champions are still alive and looking to add to their legacies at tennis' most prestigious tournament.
Here we'll rank the top women still standing at SW19 as we gear up for the round of 16.
No. 1. Serena Williams
Defending Wimbledon champion Serena Williams is without question the woman to beat this summer at the All England Club.
The overall top seed is the overwhelming favorite to repeat with 1-4 odds according to bet365.com. And it's hard to make a case against her. She's won 33 straight matches dating back to March and has won three of the past four Grand Slams.
In addition, she is a five-time Wimbledon champion and has won three of the past four titles at the All England Club.
From a physical standpoint, Williams is unrivaled at the moment. Her incredible power and strength suit her well on the grass as well, where her dominant serve gives her an even greater advantage (via Reynoldos):
No. 2. Petra Kvitova
A past champion at the All England Club, Petra Kvitova is much more dangerous than her No. 8 seed would lead you to believe.
The 2011 winner is through to the round of 16 and is flying under the radar on the bottom half of the draw as sports journalist Simon Cambers points out, which means she won't have to play Serena Williams until the final next weekend if both players can continue to win.
Kvitova has only played two matches thus far at Wimbledon, advancing easily past the second round via a walkover. And although both of her matches have gone the distance, she was aggressive in each and has been awfully impressive in the return game.
The 23-year-old Czech has 71 total wins and has won 11 total return games through the first two rounds.
No. 3. Agnieszka Radwanska
2012 Wimbledon finalist Agnieszka Radwanska is off to another strong start in London this summer.
The 24-year-old Pole is through to the round of 16 after defeating American teenager Madison Keys in the third round and now has a relatively easy path to the semifinals, where she would likely meet Serena Williams in a rematch of last year's final.
And while Williams was dominant in that match a year ago, Radwanska battled throughout, winning the second set 7-5 to force a deciding third frame. With that experience gained, tennis fans can expect a more confident Radwanska to take the court against Williams.
Although her power pales in comparison to that of Williams, Radwanska has exceptional anticipation and is a superb mover on the grass. There's great variety in her game, and that bodes well as she gears up for another deep run at Wimbledon in 2013.
No. 4. Li Na
A two-time Wimbledon quarterfinalist, Li Na is just two wins away from returning to the quarters at the All England Club in 2013.
The 31-year-old is the No. 6 seed in the women's draw this year, but will likely have a tough time playing deep into the second week considering she's in the same quarter as world No. 4 and 2012 finalist Agnieszka Radwanska.
Li beat Radwanska in the round of 16 at Wimbledon three years ago and earlier this year at the 2013 Australian Open, but she is just 1-2 against the Pole on grass all time. So while Li leads the overall head-to-head, Radwanska has the slight edge on this surface.
Keep in mind that Li has never been past the quarters here and was bounced in the second round at Wimbledon in 2011 and 2012.
