The Czech Republic reached the Hopman Cup final against France on Friday, advancing with a 2-0 victory over Denmark after No. 2-ranked Petra Kvitova beat No. 1 Caroline Wozniacki in three sets and Tomas Berdych defeated Frederik Nielsen.
The Wimbledon champion held off Wozniacki 7-6 (4), 3-6, 6-4 before Berdych breezed past Nielsen 6-1, 6-3 to clinch the top spot in Group A.
Kvitova and Berdych will play the French team of Marion Bartoli and Richard Gasquet in Saturday's final.
Kvitova can overtake Wozniacki at No. 1 if she wins the Sydney International next week.
On Friday, the Czech was up a set and a break before Wozniacki recovered to win the last four games and force a third set. Kvitova regained her composure in the third and earned an early break to set up her third win in four matches against Wozniacki.
''It was a great match from both of us. I'm very happy I won,'' Kvitova said. ''It was a small test before the Aussie Open.''
Berdych was unbeaten in the group stage, defeating Mardy Fish of the United States, Grigor Dimitrov of Bulgaria and Nielsen.
''Hopefully I can keep my winning streak with Petra and win the title,'' Berdych said.
