Daniil Medvedev and Andrey Rublev led Russia into the Davis Cup final after dominating their singles matches against Germany to win their best-of-three semifinal on Saturday.
The second-ranked Medvedev brushed aside Jan-Lennard Struff aside 6-4, 6-4 to seal the Russian victory after Rublev took the lead with a 6-4, 6-0 win over Dominik Koepfer.
Croatia awaits Russia in Sunday's final on the indoor hard court at the Madrid Arena after eliminating Novak Djokovic's Serbia on Friday. Both Russia and Croatia will be aiming for a third Davis Cup title.
With four players ranked in the top 30, Russia was favored against a German team playing without star Alexander Zverev.
Medvedev enters the final, where he should be slated to face Croatia's No. 1 Marin Cilic, after not dropping a single set at the tournament.
