Toronto, Canada – By Kevin Fylan
Nadal, who set Spain on their way to victory by winning the first point against Tomas Berdych on Friday, returned to the clay court at the Palau Sant Jordi to help himself to a 6-3 6-4 win over Jan Hajek.
Ferrer, whose exhausting five-set victory over Radek Stepanek had given Spain their second point, rounded things off with a more straightforward 6-4 6-2 win against Lukas Dlouhy, finishing off with a huge smash to the delight of the crowd.
Spain made certain of their fourth Davis Cup win when they moved into a 3-0 lead after Saturday's doubles victory for Fernando Verdasco and Feliciano Lopez against Berdych and Stepanek.
There was a slightly muted air about the celebrations when the Spanish team finally received the silver salad bowl trophy.
"It is a little strange to have to wait until today for the presentations," Spanish captain Albert Costa said in a news conference.
"But winning the Davis Cup two years in a row is a spectacular achievement. We should value it enormously."
It was a satisfying weekend all round for the hosts, with Nadal showing he has recovered form and fitness at the end of a trying season and Ferrer's heroic win over Stepanek providing epic drama with a happy ending for the huge crowd.
