CHARLESTON, S.C. ? Twins Bob and Mike Bryan led the United States into the final of the Davis Cup for the first time in seven years with a 6-1, 6-3, 7-5 victory Saturday over Max Mirnyi and Vladimir Voltchkov of Belarus.

The victory by the Bryans, the world’s seventh-ranked doubles team, set off a jubilant celebration at the Family Circle Tennis Center.

The Americans face the winner of the weekend’s other semifinal between Spain and France. If the Spanish win, they will play host to the finals. The Americans will play host if France advances. Spain led 2-1 after Saturday’s matches.

The United States has won the Davis Cup a record 31 times. But the Americans last made the finals in 1997 and last won in 1995.

Not since an 11-year gap between 1926 and 1937 has the United States gone longer without winning the Davis Cup.

The Americans built a commanding lead in the semifinals after Andy Roddick and Mardy Fish won their singles matches on Friday. During his singles match against Voltchkov, Roddick had a record 155 mph serve.

Facing elimination in the best-of-five match competition against the Americans, Belarus captain Sergei Teterin sent Mirnyi and Voltchkov onto the hard, slow surface to face the Americans.

At the Thursday draw, Belarus announced that Mirnyi and Alexander Skrypko, ranked 1,384 in the world in doubles, would play the Americans.

Substituting Voltchkov, on paper, gave Belarus a better chance to extend the competition. He is ranked No. 279 in doubles. Mirnyi is ranked No. 6.

Mike Bryan, top, celebrates while brother Bob drops to his knees after winning the doubles point in Davis Cup play. The Bryans clinched a U.S. victory over Belarus on Saturday in Charleston, S.C.

For the Bryan twins, the victory was a bright spot in a somewhat disappointing year.

They were the top seed at the Olympics but were defeated in the quarterfinals. The Bryans defeated Mirnyi and Voltchkov, 6-3, 6-3, in the second round of the Olympic competition.
