Tomas Berdych defeated Carlos Berlocq in three sets Sunday to put the Czech Republic into the Davis Cup final against Spain.
Berdych had few problems with Berlocq, winning 6-3, 6-3, 6-4 to give the Czechs an insurmountable 3-1 lead in the semifinal. Berlocq filled in for Juan Martin del Potro, who missed the decisive reverse singles with a left wrist injury.
The Czechs return to the final for the second time in four seasons and will host it in November. They will have a chance to avenge the 2009 final defeat to Spain.
Del Potro, the 2009 US Open champion, defeated Radek Stepanek on Friday but was ruled out for Sunday by the Argentina team doctor, who said the match made his injury worse. Del Potro has a history of wrist injuries.
Argentina was trying to reach its fifth Davis Cup final. It has lost all four, including last year against Spain.
There wasn't enough firepower with del Potro absent and David Nalbandian -- the team leader for several years -- sidelined with an abdominal injury.
Argentina's chances faded quickly Saturday. The loss in doubles to Berdych and Stepanek was followed by del Potro's withdrawal, leaving only Berlocq -- who has never won an ATP event -- to face No. 6-ranked Berdych. Even Diego Maradona, cheering in the stands for the third straight day, could not inspire Berlocq on the red outdoor clay at Parque Roca.
Berdych won all three points for the Czechs. He beat Juan Monaco on Friday 6-1, 4-6, 1-6, 6-4, 6-4, then teamed with Stepanek for a three-set win in doubles to set up his clincher Sunday.
It was Berlocq's Davis Cup debut in singles after losing Saturday in doubles with Eduardo Schwank.
