Ostrava, Czech Republic: Defending champions Czech Republic reached the quarterfinals of the Davis Cup on Sunday after Tomas Berdych won the first reverse singles to clinch the first-round tie 3-1.
Berdych, an Australian Open semifinalist, dispatched Thiemo de Bakker 6-1, 6-4, 6-3 on an indoor hard court at CEZ Arena.
Berdych was never threatened and converted his first match point with a forehand winner.
Seeking their third straight Davis Cup title, the Czechs won the 10th consecutive Davis Cup series. They will travel for the April 4-6 quarterfinal to Japan, which beat Canada 4-1 in another first-round tie.
The result of the second reverse singles match cannot change the overall Czech victory in the best-of-five series.
