Bryan brother clinch Cup

The Americans, who won the opening singles matches at Memorial Coliseum, had not claimed the team title for 12 years, their last success also coming against Russia on the clay of Moscow in 1995.

The dominant Bryan brothers, winners of five grand slam titles together, crushed their opponents in just under two hours to secure their 13th doubles triumph in 14 Davis Cup appearances.

"We will remember this for the rest of our lives," a beaming Mike Bryan said in a courtside television interview. "It's difficult to explain how we feel right now."

Andy Roddick, who won the opening rubber and is unbeaten in six Davis Cup singles matches this year, added with a smile: "This is one of our greatest moments."

Although the Bryans squandered an early break point off Andreev's serve in the opening set, they won the tiebreak 7-4 on an Andreev double-fault after coming from 3-1 down.

Roared on by a near-capacity crowd, the Bryans broke Davydenko in the first game of the second set and held serve to establish a commanding two-set lead.

World number four Davydenko, a surprise omission from the opening singles matches, was again broken in the third and seventh games of the third set before right-hander Mike served out the match.

Confetti sprayed into the air as U.S. team mates Andy Roddick and James Blake ran on to the court to join the Bryan brothers in a celebratory huddle.

American number one Roddick had outclassed Dmitry Tursunov 6-4 6-4 6-2 in the opening rubber of the three-day tie before Blake put the hosts 2-0 up with a gutsy 6-3 7-6 6-7 7-6 victory over Mikhail Youzhny in the second singles.

Holders Russia, who beat Argentina in last year's final in Moscow, have now lost to the U.S. three times in four Davis Cup ties.

With the 2007 title decided, Sunday's reverse singles matches at Memorial Coliseum will be shortened to the best-of-three sets.
