MAR DEL PLATA, Argentina — Spain's Feliciano Lopez and Fernando Verdasco defeated Argentina's David Nalbandian and Agustin Calleri 5-7, 7-5, 7-6 (5), 6-3 today.

Spain leads 2-1 heading into the last day of the Davis Cup final.

Playing without top-ranked Rafael Nadal, who is sidelined with a knee injury, Spain can clinch the title on Sunday. Spain's David Ferrer will meet Juan Martin del Potro in the first reverse singles match. If he loses, Lopez will face Nalbandian in the final match at Islas Malvinas Stadium.

Argentina needs to win both matches to win its first title.
