Mar Del Plata, Argentina -- Argentina's David Nalbandian will face Spain's David Ferrer today in the opening match of the Davis Cup final.

Juan Martin del Potro, Argentina's top-ranked player at No. 9, was drawn Thursday to play Feliciano Lopez in the second singles match of the best-of-5 series.

"Juan Martin had a slight preference to play second," Argentina captain Alberto Mancini said. "And the fact that David is first is good because he has more experience."

In Saturday's doubles, Jose Acasuso and Agustin Calleri of Argentina will play Lopez and Fernando Verdasco.

The reverse singles will be held Sunday.
