Coach of the Argentine Davis Cup team Modesto Vazquez appointed six players for the quarterfinal against Russia from July 9 to 11 in Moscow, according to David Nalbandian’s official website.

Vazquez summoned Nalbandian, Monaco, Leonardo Mayer, Horacio Zeballos, Eduardo Schwank and Federico Delbonis. Meanwhile, Juan Martin Del Potro is recovering from a surgery in his right waist so he is discarded to play.

David Nalbandian has sent Argentina into the Davis Cup quarterfinals by defeating Sweden's Andreas Vinciguerra in the last reverse singles for a 3-2 series win.
