The world number one and Australian Open champion Novak Djokovic's victory over American Sam Querrey has advanced Serbia to the semi-finals of the Davis Cup.
Djokovic, who had to battle through an ankle injury he suffered in the opening set, earned a 7-5 6-7 (4-7) 6-1 6-0 win to give the Serbians an insurmountable 3-1 lead in the best-of-five tie against the Americans.
It is the second win for Serbia in four years over the 32-time titlist USA. In their only other previous Davis Cup encounter Serbia defeated the Americans in Belgrade in 2010.
Serbia will now meet either Canada or Italy in the semi-finals in September.
Meanwhile Argentina advanced to the Davis Cup World Group semi-finals after their world No.71 Carlos Berlocq beat Frenchman Gilles Simon to hand the South Americans a 3-2 win.
Argentina will face defending champions Czech Republic after they eliminated Kazakhstan earlier in the day.
Elsewhere Australia clinched victory over Uzbekistan to advance to September's World Group playoffs.
