Prague - Petra Kvitova and Lucie Safarova gave the Czech Republic a 2-0 lead over Germany in the Fed Cup final here on Saturday after winning their opening rubbers in straight sets.
Kvitova, the Czech number one player and world number four, swept Germany's number two Andrea Petkovic 6-2, 6-4 in an hour and 17 minutes.
Safarova then needed an hour and 28 minutes to beat Germany's Angelique Kerber 6-4, 6-4.
In the reverse singles on Sunday, Kvitova will play Kerber and Safarova will then take on Petkovic.
If the finals come down to a doubles rubber, Andrea Hlavackova and Lucie Hradecka are due to play against Germany's Julia Goerges and Sabine Lisicki.
The Czechs are eyeing their third Fed Cup win in four years after lifting the trophy in 2011 and 2012.
Germany are looking for their first title since 1992, when a team led by Steffi Graf and current captain Barbara Rittner won the title.
