Holders Spain reached their fourth Davis Cup final in five years when David Ferrer overcame the big-serving John Isner to help beat the United States 3-1 in the last-four tie on Sunday.
World number five Ferrer had to fight from a set down on the clay in the northern Spanish coastal city, coming through 6-7 (3), 6-3, 6-4, 6-2 against the 10th-ranked Isner in exactly three hours for his 16th victory in 16 singles rubbers on clay.
"It was a very tough, very difficult tie but we are really happy as we are in another Davis Cup final, something that is extremely hard to achieve," Ferrer said in an interview with Spanish television.
Spain will play away against Czech Republic, whom they beat in the 2011 and 2009 finals respectively, in November's title clash. Those finals, their most recent meetings with the two nations, were at home and competition rules dictate the next must be away. The Czechs took an unassailable 3-1 lead against Argentina in Buenos Aires, when Tomas Berdych beat Carlos Berlocq 6-3, 6-3, 6-4 in Sunday's first reverse singles, following the withdrawal through injury of Juan Martin del Potro.
