PRAGUE (AP) - The Czech Republic won the doubles Saturday to take a 2-1 lead over defending champion Spain in the Davis Cup final, moving one win away from its first title as an independent nation.

Tomas Berdych and Radek Stepanek rallied to beat Marcel Granollers and Marc Lopez 3-6, 7-5, 7-5, 6-3 to give the Czechs the edge going into Sunday's reverse singles.

The Czechs converted their third match point in front of more than 13,000 loud fans at the O2 Arena to improve their Davis Cup doubles record to 12-1.

The sixth-ranked Berdych can clinch the best-of-five series in the first reverse singles Sunday with a victory over David Ferrer.

Spain is looking for its fourth title in five years, while the Czechs' only victory came in 1980 as Czechoslovakia, which split in 1993.
