NEW YORK (AP) Andy Roddick's match against David Ferrer at the U.S. Open has been moved to tiny Court 13 because of a problem with water gathering on the surface of the court in Louis Armstrong Stadium.

After two days of rain at the Grand Slam tournament, Roddick and Ferrer were able to play for less than 10 minutes Thursday. They got two games in before Roddick pointed out a spot where water was seeping up onto the playing surface.

While workers tried to dry the area, Roddick and Ferrer headed to the locker room. About an hour later, they returned to Louis Armstrong Stadium, but the court still wasn't usable. So they shifted from the tournament's second-biggest arena holding 10,103 seats to its smallest show court with 584 seats.
