It was the 27-year-old's third best-of-five sets match since his 13th Grand Slam title in New York on Monday.
But the Majorcan said that having made the effort to come and play in Spain after the rigours of his US Open campaign, it was only a small extra demand to play in the doubles.
Nadal said: "We had the match under control, but at the start of the second set I had a bit of a slump.
"But we got the breaks in the third and fourth sets at the right moment and were able to finish the match off.
"We are still in the World Group and I think that a country with so many players in the top 100 deserves it."
