Second-ranked Daniil Medvedev helped Russia beat Ecuador at the Davis Cup finals on Saturday, setting up a clash with Spain to decide which will go through as a group winner.
Medvedev eased past Emilio Gómez 6-0, 6-2 after breaking his serve five times to give Russia an insurmountable 2-0 lead.
"I wanted to keep it clean from the first to the last point of the match and I am happy to bring the point to the team," the U.S. Open champion said.
Teammate Andrey Rublev started the tie with a more difficult than expected 6-3, 4-6, 6-1 win over Roberto Quiroz.
The doubles was played later.
