The first week is over, so who is still playing?

Those reaching the men’s round of 16 at Wimbledon include six players aged 27 or older, among them Tommy Haas, 31, and Radek Stepanek and Ivo Karlovic, both 30. The message is clear – when it comes to the brief lawn tennis season, experience pays.

On the women’s side, Russians made up a quarter of the final 16. And unlike on the men's side, youth is serving up victories.

Two teenagers, 19-year-old Victoria Azarenka of Belarus and 18-year-old Caroline Wozniacki of Denmark, are into the second week.

On the men’s side, 13 countries remained represented, reflecting the global reach of the sport.

All 16 fourth-round matches are scheduled for today, and the feature battle will be five-time champion Roger Federer against Robin Soderling. Even though Federer is listed at -3000 to win, it won't be as easy as many think.
