Russia knocked reigning champion Spain out of the Davis Cup on Sunday to set up a quarter-final against Sweden.
The Russians’ tie against the depleted Spanish team came down to a late-night doubles encounter in Madrid.
Aslan Karatsev and world number five Andrey Rublev won 4-6, 6-2, 6-4 against Marcel Granollers and Feliciano Lopez to win Group A and deprive the Spanish team of the chance to play in front of a home crowd in Madrid on Thursday.
The Russians, playing under the name of the Russian Tennis Federation because of sanctions against Russian sport for doping, made a bad start to the tie when Lopez beat Rublev 2-6, 6-3, 6-4 in the opening singles rubber.
