The US Open tennis tournament officially kicked off this week. Favorites Venus and Serena Williams are already in action, and we can't wait to see the wins these ladies take home. (Venus has already beat the higher ranked Kirsten Flipkens, while Serena whipped 2010 French Open champion Francesca Schiavone.) Whether you watch tennis or not, track the scores or not, there's no denying that the sisters put on a show, and that's one thing anyone can enjoy!
In fact, check out these shots of the Williams sisters playing hard ball and basically kicking arse over the past 3 years.
