Last year the women's Wimbledon finals brought the Williams sisters to center court rallying through two sets of sibling rivalry, with Venus coming out the champ. The men's final was super exciting with Federer and Nadal battling for five long sets. In fact it was the longest men's final match in the history of Wimbledon. The world renowned tennis match opened today, but unfortunately Rafael Nadal will not be competing — he is sitting out to nurse his injured knees. But, by the message on her shirt, Serena Williams looks ready to take on whoever comes her way, both on and off the court.
