Argentina's reply was swift and deadly, tighthead prop Tomas Ramirez latching on to the end of a lineout drive for his try.
First-five and captain (for Argentina) Patricio Fernandez was sinbinned for constant offside. Italy were quick to capitalise when Bruno left his marker for dead to touch down in the corner.
Argentina manufactured a try in the corner, finally confirmed by the TMO, to No12 Bautista Ezcurra to help tie it up at 20-all. Buscema, Italy's captain and general, popped over a dropped goal, which was ultimately the difference.
Italy 29 (Gabriele di Giulio, Lorenzo Maria Bruno tries; Filippo Buscema 2 cons, 4 pens, dg)
Argentina 26 (Tomas Ramirez, Bautista Ezcurra tries; Patricio Fernandez 2 cons, 4 pens). HT: 17-13.
