Italy had taken a surprise 1-0 lead over Spain in their Davis Cup World Group play-off on Friday after Andreas Seppi produced a tremendous fight back from two sets down to beat Juan Carlos Ferrero.
Seppi beat Ferrero 5-7, 3-6, 6-0, 6-3, 6-2.
The Spaniard looked below his best despite taking the opening two sets 7-5 and 6-3, largely thanks to unforced errors from Seppi, but he was crushed 6-0 in the third set as the Italian kept the match alive.
Seppi, 58 places below 20th-ranked Ferrero, brought the match level with an impressive 6-3 win in the fourth set and then cruised to a 6-2 victory against the tired-looking Spaniard to take the game.
