But Bruguera's 6-3, 6-2 victory was the only bright spot for Spain as Russia won the tie 2-1. It was their second defeat in as many days and ended Spanish hopes of a fourth World Team Cup title.
Alberto Berasategui went down 6-4, 6-1 to Andrei Chesnokov and in the decisive doubles Bruguera and Carlos Costa were beaten 6-4, 6-3 by Kafelnikov and Andrei Olhovskiy.
Bruguera, the world No 7, took just an hour to dispose of the ninth-ranked Kafelnikov despite an uncertain start which saw him trail 0-2.
Kafelnikov has had a string of disappointing results, including a first- round defeat at the Italian Open last week in Rome. "I'm tired, tired mentally. With the way I'm playing now I don't feel I can even win one match in Paris." he said.
Bruguera, who suffered a knee ligament injury in February, said: "I still feel a difference between the right and left leg. It's not a question of being an injury any more, but of strength and power."Reuse content
