The US Davis Cup team celebrates its win over Russia Saturday in Portland.

The United States has taken an unbeatable 3-0 lead over Russia to capture the Davis Cup tennis title for the first time in 12 years.

In front of a cheering crowd in Portland, Oregon, the world number one doubles team of brothers Bob and Mike Bryan of the United States defeated Igor Andreev and Nikolay Davydenko in straight sets, 7-6, 6-4, 6-2.

The reverse singles Sunday are now meaningless or so-called "dead rubbers." Andy Roddick of the United States faces Mikhail Youzhny and James Blake plays Dmitry Tursunov.

The win gives the United States the Cup for the first time since 1995, when Pete Sampras led the Americans to a 3-2 win over Russia on clay in Moscow. The United States has captured the Cup a record 32 times.
