SEVILLE, Spain — The Czech Republic beat defending champion Switzerland on the first day of the group stage at the Billie Jean King Cup Finals on Tuesday.
Linda Noskova defeated Celine Naef 7-6 (2), 4-6, 6-4 in the first singles match, and Marie Bouzkova beat Viktorija Golubic 6-4, 6-4 in the second match of the Group A tie.
Bouzkova was a late addition to the Czech team following the withdrawal of world No. 8 Karolina Muchova because of a wrist injury.
Switzerland was without Olympic gold medalist Belinda Bencic, who announced Friday that she is pregnant.
The United States is the other team in Group A and will face Switzerland on Thursday.
In Group B, Slovenia defeated last year’s runner-up, Australia, 2-1 after Kaja Juvan defeated Ajla Tomljanovic 6-4, 6-1 and Tamara Zidansek beat Daria Saville 6-1, 6-4.
Australia’s point came when Kimberly Birrell and Storm Hunter beat Veronika Erjavec and Ela Nala Milic 7-5, 6-7 (2), 10-5 in the doubles match.
The 12-team BJK Cup Finals is being played at La Cartuja Stadium in the southern Spanish city of Seville. It will run through Sunday offering a record $9.6 million in prize money, including $2.4 million to the champions.
The teams compete in four round-robin groups and the winners will advance to the semifinals.
The biggest team competition in women’s tennis is starting two days after the end of the WTA Finals in Cancun, Mexico, which featured the top eight players on the tour — including winner Iga Swiatek.
