Martin de la Puente and Daniel Caverzaschi booked Spain’s place in the men’s final after winning both of their semi-final singles rubbers against Croaitia.

World number 21 Viktoriia Lvova then beat Margrit Fink 6-1, 7-5.

Ludmila Bubnova and Lvova took the doubles 6-1, 6-2 as Russia also made it three 3-0 victories in Portugal this week.
