Spain has caused the biggest upset on Argentine soil and won the 2008 Davis Cup by BNP Paribas, after Fernando Verdasco pulled through a five-set thriller of a fourth rubber against Jose Acasuso to hand the visitors their third Davis Cup title and first on away soil. It was a fitting end to the 2008 season for the Spaniards, who have not only been the leading nation all year on the tennis tour, but proved this weekend that even without Rafael Nadal, they are a winning combination.
