Get ready for the Washington Kastles. The newest addition to World TeamTennis will begin play this season, which opens July 3. First they will have to find a venue somewhere around town and draft players on April 1. We’re telling you this now so that you won’t think our “Tennis Draft” article is an April Fools gag.

WTT teams play a month-long season with 11 games, followed by a championship. Games are shorter than regular tennis games, ending when the first player gets to four points. Sets, however, can be longer, going into overtime until the player who leads in points wins a game.

The Kastles will presumably join the Eastern Conference and compete against teams like the Delaware Smash, Boston Lobsters and New York Buzz. The Buzz, led by veteran John McEnroe, made it to the finals in 2007 before losing to Anna Kournikova’s Sacramento Capitals.

The Kastles’ ownership group is led by local venture capitalist Mark Ein. Ein says on the team’s website, “I am thrilled to bring World TeamTennis to our area. WTT tennis is great entertainment emphasizing fan interaction, and it is the only major sport with men and women playing together on the same team. The Washington Kastles season will be an exciting summertime addition to our local economy and a fun activity for our entire community.”

We’re just wondering what a Kastle is.
