Uncasville, Feb 10: Andy Roddick hits fastest serve ever to help the United States to a 2-0 lead in their Davis Cup tie with Austria. Andy Roddick set a new serving speed record before powering the United States to a 2-0 lead over Austria on the opening day of their first-round Davis Cup World Group tie on Friday (February 6).

The world number two dismantled Stefan Koubek 6-4 6-4 6-2 to give the Americans a huge advantage after Robby Ginepri had earlier battled back from two-sets down to beat Jurgen Melzer, 6-7 4-6 6-4 6-4 6-2.
Roddick, the 21-year-old U.S. Open champion, needed only 91 minutes to improve to 4-0 lifetime against Koubek in a match that included the fastest ever recorded serve of 150 mph. The blast came on the American's first serve of the match and he equalled the feat later in the opening set. The previous mark was held jointly by Roddick and Britain's Greg Rusedski at 149 mph.

With the victory, Roddick improved to 2-3 in Davis Cup play. Despite setting the new mark, Roddick admitted that he was more concerned about his overall serving performance and the result for himself and the team.


"At the end of the day, the thing that matters is that I didn't get broken. And that's the one thing that I'll take any day," he said.
