TOKYO (AP) -- Radek Stepanek and Lukas Rosol won their singles matches Friday to give the defending champion Czech Republic a 2-0 lead over Japan in the Davis Cup quarterfinals.

Stepanek beat Tatsuma Ito 6-7 (5), 7-6 (5), 6-1, 7-5 at Ariake Coliseum and Rosol defeated Taro Daniel 6-4, 6-4, 3-6, 4-6, 6-2.

In Saturday's doubles, Stepanek and Jiri Vesely are scheduled to face Ito and Yasutaka Uchiyama.

Kei Nishikori, Japan's top-ranked player, was forced to withdraw because of a groin injury. The Czech team is also missing its top player, with Tomas Berdych sitting out following two tough tournaments in the United States.
