Roddick clinches Davis Cup series for U.S.

The United States turned to Andy Roddick to put away another Davis Cup, and he delivered - as usual. Roddick swept past Switzerland's Stanislas Wawrinka 6-4, 6-4, 6-2 to give the U.S. a 4-1 opening-round victory Sunday in the best-of-five series at Birmingham, Ala., pretty much wiping out any final-day drama.

Roddick, ranked sixth in the world, is now 11-0 with a chance to close out a Davis Cup series.

If he felt any pressure from teammate Mike Bryan's guarantee of a Roddick win a day earlier, it didn't show on the court.

"I was sitting there putting my shoes on and (Bryan) goes, 'I guarantee a victory,' " Roddick said. "I kind of progressively got tighter and tighter as he was talking. But I guess it would have been easy to blame him if I had lost. I guess he ended up looking smart."

Next for the U.S. is Croatia in the quarterfinals July 10-12.
