Wimbledon Day 4, Round 2

The weather interrupted several matches today at Wimbledon, but most of the top seeds were able to finish their matches before play was called on account of darkness.

Federer, Djokovich, Soderling, and Tsonga all won their matches today.

One upset potentially brewing was American Ryan Harrison leading #7 seeded David Ferrer 7-6, 1-6, 6-4, 2-4 when play was suspended at the end of Thursday.

Harrison is a virtual unknown to the casual American tennis viewer, but the 19 year-old has accomplished some rare things since he has turned pro in 2007. He won the US Clay Court Championships in 2008, becoming the 10th player in ATP history to win a title before turning 16. With that win, he also became the 3rd youngest player to win an ATP title (one of those other guys was Rafael Nadal).

Harrison is currently ranked #122 and has never advanced to the 3rd round of any Grand Slam tournament.
