BUENOS AIRES — Argentina completed a surprise two-day Davis Cup victory over Serbia when Leo Mayer and Carlos Berlocq teamed up to win the doubles for an unassailable 3-0 lead in their quarter-final on Saturday.
The Argentine pair beat Viktor Troicki and veteran Nenad Simonjic, playing his 50th Davis Cup tie, 6-2 6-4 6-1 after Friday's singles victories for Mayer over Filip Krajinovic and Federico Delbonis's upset against Troicki.
Argentina went into the tie without their top player Juan Martin del Potro, who is recovering from wrist surgery, but were still the underdogs even when Serbia's world number one Novak Djokovic opted against travelling to Buenos Aires on the back of his Wimbledon victory.
