Andy Roddick pulled the United States level with Switzerland in their Davis Cup World Group tie yesterday after Stanislaus Wawrinka shrugged off the absence of Roger Federer to put the visitors ahead.

Roddick defeated Marco Chiudinelli 6-1, 6-3, 7-6 (7/5) to knot the score in the best-of-five match tie at 1-1 at the end of the first day.
