The 23-year-old then fittingly secured the winning point by seeing off Facundo Bagnis 7-5, 6-1.

"It's an incredible feeling to play this kind of tennis in front of the home crowd," said world number 43 Ruusuvuori.

The weekend's 12 winners all go through to the group finals in September where they will be joined by 2022 champions Canada, runners-up Australia and wild cards Spain and Italy.
