The Czech Republic won the doubles Saturday to take a 2-1 lead over defending champion Spain in the best-of-five 2012 Davis Cup final.
The Czech duo of Tomas Berdych and Radek Stepanek beat Marcel Granollers and Marc Lopez by a 3-6, 7-5, 7-5, 6-3 margin on a fast indoor hardcourt at Prague's O2 Arena.
The best-of-five tie was even at 1-1 after David Ferrer and Berdych were opening singles winners on Friday.
Berdych will try to clinch the series for the Czech Republic in the first reverse singles Sunday with a victory over Ferrer. The second reverse singles will pit Stepanek against Nicolas Almagro.
Spain is playing without injured superstar Rafael Nadal, who has been sidelined with knee problems since June.
The Spaniards are captained by former top-five star Alex Corretja, while the host Czechs are piloted by Jaroslav Navratil.
Five-time champion Spain has won three of the last four Davis Cup titles, including a 5-0 sweep of the Czech Republic in the '09 finale. The former Czechoslovakia captured its lone Davis Cup title in 1980, led by the legendary Ivan Lendl, who was in attendance on Friday.
Spain is 4-2 all-time versus the Czechs, including 2-0 against the Czech Republic. The Spaniards went 2-2 against the former Czechoslovakia in a series that started back in 1931.
The last road team to win the Davis Cup final was Spain in 2008.
Czech women captured a second straight Fed Cup title at O2 Arena just two weeks ago.
