Spain has taken a 2-0 lead over the United States in the first day of the Davis Cup tennis finals in Seville after Spanish teenager Rafael Nadal beat former U.S. Open champion Andy Roddick in singles, three sets to one.

Roddick won the first set, 7-6, but lost the next three, 6-2, 7-6, 6-2. The match lasted three hours and 38 minutes.

Earlier, Spain's Carlos Moya scored a straight sets win over Olympic silver medalist Mardy Fish, 6-4, 6-2, 6-3. Saturday's doubles pits Nadal and Tommy Robredo against American twins Bob and Mike Bryan. Spain would clinch the best-of-five match final with a victory in doubles. The reverse singles matches are set for Sunday.

Spain is appearing in its third Davis Cup final in five seasons. Spain last captured the trophy in 2000 with a 3-1 win over Australia in Barcelona. The United States is trying to win its first Davis Cup crown since 1995.
