The Czech Republic advanced to the Fed Cup semi-finals for the third time in a row after Petra Kvitova handed them an unbeatable 3-0 lead over hosts Slovakia in Bratislava on Sunday.
Kvitova, the world number 18, swept aside Daniela Hantuchova 6-4, 6-2 in 67 minutes in the first of Sunday's reverse singles.
The left-handed Czech team won both singles on Saturday as Lucie Safarova beat Hantuchova 7-5, 6-1 and Kvitova thrashed Dominika Cibulkova 6-2, 6-3.
"I hope the Czech team will go for it. We have a strong and well balanced team capable of playing against anyone," said Kvitova, whose team will play either Belgium or the USA in the semi-finals. Belgium was 2-0 up after day one on Saturday.
The Czechs now have a perfect 4-0 record over the Slovak Republic, having met in 2000, 2007 and 2008.
The two nations played under the same flag as Czechoslovakia before the country split in 1993.
Slovakia are competing in the World Group for the first time after seven years, while the Czech Republic reached the Fed Cup semi-finals in the last two years.
