( CNN ) -- Tomas Berdych has hovered around the edge of the `` big four '' of men 's tennis for the past three years , but on Sunday he will take center stage in what could be a historic moment for his country . The Czech Republic has not won the Davis Cup since its split from Slovakia in 1993 , but its men 's team are poised follow up its women 's success in the Fed Cup after taking a 2-1 lead in the final against defending champions Spain . The women retained their title in the tournament 's 50th staging , and the men are battling to follow up Czechoslovakia 's sole 1980 victory as the 100th edition of the Davis Cup comes to a climax in Prague . `` That 's all we wanted , '' Berdych said after helping Radek Stepanek to defeat the ATP World Tour Finals champion partnership of Marcel Granollers and Marc Lopez 3-6 7-5 7-5 6-3 in Saturday 's doubles rubber . `` We are still missing a lot , it 's just one point , but we are looking ahead and we will do everything . '' Jubilant Czechs clinch 'amazing ' Fed Cup title defense . Berdych is ranked sixth in the world in singles play , and 119th in doubles , but he has come to the fore in the Davis Cup this season with 10 wins from 10 matches . Friday 's victory over Nicolas Almagro , which leveled the final , was his first over a Spanish player after three previous defeats -- including the 2009 final when the Czechs were whitewashed 5-0 in Barcelona . On Sunday he will play fifth-ranked David Ferrer , who has a leading seven tournament titles this year and 74 match wins -- second only behind world No . 1 Novak Djokovic . Ferrer has a 22-4 record in Davis Cup matches , including Friday 's win over Stepanek , and he holds a 5-3 career advantage in matches against Berdych . Ferrer is also unbeaten in Davis Cup action this year , and is leading the Spanish team in the absence of the injured Rafael Nadal . If he beats Berdych in their first encounter this year , then the final will hinge on the fifth rubber between 37th-ranked Stepanek and world No . 11 Almagro . Almagro has an 8-3 Davis Cup record , but did not feature in last year 's final or his country 's triumphs in 2004 , 2008 , and 2009 .
