Last night, the Washington Kastles -- Venus and Serena Williams' tennis team and the 2011 WTT Champions -- hosted a season kick-off party.

The event, which took place at Poste at the Hotel Monaco in Washington, D.C., was attended by Kastles management, Radio Celebrity Tommy McFly, Kastles Mascot Topspin and the beautiful Kastles chearleaders.

The Kastles opened its fifth season last night in Orange County against the breakers. The match was streamed live at WashingtonKastles.com. Their first home match will be this Thursday, July 12, at 7 p.m. EDT against Martina Hingis and the New York Sportimes at Kastles Stadium at the Wharf. If last year was any indicator, this years games will likely sell-out quickly, so -- if you are in our Nation's Capital -- get your tickets now!
