Bryan and Fish, who replaced Bob Bryan when he backed out of the event with a shoulder injury, outlasted the Spaniards 4-6, 6-4, 6-3, 4-6, 6-4 in a match that lasted three hours, 16 minutes.

Spain now leads the best-of-five tie, 2-1, with a pair of singles matches Sunday. Rafael Nadal is set to face Andy Roddick and David Ferrer will meet Sam Querrey.

Nadal rallied from a set down to beat Querrey to give Spain the early lead in Friday's opening singles play. Ferrer then outlasted Roddick in the second match 7-6 (7-5), 2-6, 1-6, 6-4, 8-6.
