David Nalbandian and Juan Monaco have been selected to Argentina's Davis Cup for next month's opening round against Romania.

Captain Modesto "Tito" Vazquez also picked Juan Ignacio Chela and Eduardo Schwank on Monday, saying he expects them to play doubles in the March 4-6 series on clay in Buenos Aires.

Vazquez says he is confident Nalbandian will be fit after injuring his groin in Saturday's loss to Tommy Robredo at the Copa Claro in Buenos Aires. Nalbandian has withdrawn from this week's Mexican Open in Acapulco, The Associated Press reported.
