The Washington Kastles, D.C.’s one-year-old team in the World TeamTennis (WTT) league, announced their 2009 schedule today. The Kastles are set to host seven home matches this summer, along with the 2009 Advanta WTT Championship Finals in July. Team star Serena Williams will play in one home appearance, and throughout the season visiting star players Venus Williams, Anna Kournikova and John McEnroe will also play here in Washington.

A temporary tennis stadium will once again be erected at CityCenterDC for Kastles matches this summer, reaffirming the fact that the CityCenterDC development itself, on the site of the old convention center, appears to be stalled indefinitely in the face of the current financing market. Kastles Stadium, which is indeed a pretty sweet venue with all of the downtown buildings surrounding it, will also be 30 percent bigger this year, bringing the total number of seats to around 3,000.

The team lineup this year, led by Head Coach Murphy Jensen, includes Leander Paes, Angela Haynes, CoCo Vandeweghe (defending U.S. Open Junior Champion), and returning Kastle Scott Oudsema. Tickets for all seven home matches and the Advanta WTT Finals go on sale to the general public on Monday, May 11 at 10 a.m. through www.washingtonkastles.com or Ticketmaster. Season tickets, season boxes and group sales can be purchased by calling 202-4TENNIS (483-6647).
