The Czech Republic finished off a 3-0 victory here over Argentina in the Davis Cup semifinals with a straight-set win in Saturday's doubles.
Radek Stepanek and Tomas Berdych, who improved their record as a Davis Cup doubles duo to 13-1, cruised to a 6-3, 6-4, 6-2 win over the Argentine tandem of Horacio Zeballos and Carlos Berlocq.
Their only loss came in the 2009 Davis Cup final against the Spanish team of Feliciano Lopez and Fernando Verdasco.
The Argentines, who had chances to break the Czechs' serve in the seventh game of the match and take a 4-3 lead, paid dearly for their numerous unforced errors in surrendering the first set.
In the sixth game of that initial set, Stepanek, who underwent spinal surgery early this year, felt discomfort in his back but managed to battle through the pain and come up with a crucial second-serve ace.
The Argentines then proceeded to smooth the path for their opponents with several easy forehands missed and lots of netted volleys off the racquet of Berlocq.
The Czechs merely needed to hold on to their service games and wait for mistakes from the Argentines to take the match in just over two hours.
"It's an honor to play in this atmosphere," Stepanek told the crowd of 11,000 that packed Prague's O2 Arena after the Czechs had clinched a berth in this year's Davis Cup final.
The defending champion Czechs will face off against either Serbia or Canada for the Davis Cup title in November.
Those two squads were tied 1-1 after Friday's singles. EFE
