It has proven a fantastic week for Sramkova with this her third successive triumph after defeating the USA’s Danielle Collins and Australia’s Ajla Tomljanovic.
The tie will now be decided by doubles, with Great Britain’s partnership between Olivia Nicholls and Heather Watson so far untested at the Finals.
Slovakia duo Hruncakova and Tereza Mihalikova, meanwhile, joined forces to great effect against the United States as they dispatched Ashlyn Krueger and Taylor Townsend.
There is all to play for.
