Picture of the Day: Roddick karate kicks Chile after Davis Cup win

Andy Roddick celebrated his twelfth-straight win in a decisive Davis Cup tie in the same way anybody would: by karate chopping the air in the style of Chuck Norris.

Little known fact: Clay courts used to be a dull gray color but were changed to red in order to commemorate Chuck Norris' chest hair.

Roddick's kick will have to be extra-high if he and the Americans want to win their next tie. In four months, the U.S.A. will host Spain in the Davis Cup quarterfinals (the site is yet to be determined, but Roddick's hometown of Austin is a favorite). Rafael Nadal says he'll play, but plans could change depending on how he performs at Wimbledon.
