Argentina wins doubles against Spain to cut Davis Cup final deficit to 2-1

SEVILLE, Spain - Argentina won the doubles against Spain to stay alive in the Davis Cup final and cut the hosts' lead to 2-1 on Saturday.

David Nalbandian and Eduardo Schwank, partnering for the first time, eased to a 6-4, 6-2, 6-3 victory over Spanish pair Fernando Verdasco and Feliciano Lopez on the clay at Olympic Stadium.

The South Americans broke five times and repelled each of the three they faced against their Spanish counterparts to extend the tie into Sunday. The visitors need to sweep Sunday's reverse singles to become the first team in 72 years to rally from a 2-0 deficit.

Such an achievement appears difficult with Rafael Nadal, unbeaten on clay in the cup, opening for four-time champion Spain.
