The Czechs had already clinched the best-of-five tie with a doubles victory in Ostrava on Saturday, which gave them an unassailable 3-0 lead. On Sunday, a pair of dead rubbers saw Czech Lukas Rosol overcome Andreas Seppi 4-6, 6-3, 6-4 and Italian Simone Bolelli top Frantisek Cermak 6-4, 6-4 on the indoor hardcourt at CEZ Arena.
Friday's opening singles rubbers featured Czech victories for Radek Stepanek and 2010 Wimbledon runner-up Tomas Berdych, and Stepanek and Berdych then followed up their singles victories from Day 1 with a doubles triumph on Saturday.
The Czechs are to 8-3 all-time against Italy, which captured its lone Davis Cup title in 1976. The former Czechoslovakia was the champion in this prestigious international event back in 1980.
