Lukas Rosol and Radek Stepanek of the Czech Republic scored a comprehensive 6-4, 6-4, 6-4 victory over Japan's Tatsuma Ito and Yasutaka Uchiyama in doubles on Saturday in their Davis Cup World Group quarterfinal.
The victory clinched the tie 3-0 for the two-time defending champions, who will now advance to a semifinal in September against the winner of the quarterfinal between Germany and France this weekend.
Rosol and Stepanek factored in all three wins in the quarterfinal. The Czechs entered the tie with just a three-man team.
