The Czech Republic will defend its Davis Cup crown against Serbia.
The tandem of Tomas Berdych and Radek Stepanek gave the Czechs an insurmountable 3-0 lead in the best-of-five semifinals tie against Argentina by winning Saturday's doubles rubber.
Argentina did close out the semifinals on a high note, as Horacio Zeballos and Leonardo Mayer swept Sunday's singles rubbers. Zeballos rallied to beat Lukas Rosol, 4-6, 7-6 (8-6), 6-4, while Mayer posted a 6-4, 6-4 victory over Jiri Vesely.
The Czechs captured their first Davis Cup title last year by beating perennial powerhouse Spain. They will look to repeat in November's finals.
