Jan Hajek defeated Mikhail Kukushkin 6-3, 6-2, 6-4 in the opening singles Friday, giving the defending champion Czech Republic a 1-0 lead over Kazakhstan in their Davis Cup quarterfinal.
Kazakhstan's Andrey Golubev was scheduled to play Lukas Rosol in the second singles.
Hajek saved a break point in the third game before breaking Kukushkin in the eighth and then serving out the first set. The Czech won five consecutive games in the second set and broke immediately in the third. Kukushkin, who beat Hajek to score the winning point in Kazakhstan's 3-2 surprise victory over the Czechs in the first round in 2011, couldn't challenge his opponent's solid game this time.
The winner of the best-of-five series will face either Argentina or France in the semifinals in September.
