MADRID -- US Open champion Rafael Nadal helped Spain win its doubles match Saturday and capture its Davis Cup World Group playoff against Ukraine.
"We played at a good level," Nadal said. "In my case, I had a moment I felt tired but later we were able to recover. We achieved our goal and that's the important thing."
Nadal and Fernando Verdasco won singles matches Friday. Captain Alex Corretja paired Nadal with Lopez, intent on preventing the series from going to reverse singles Sunday.
Nadal won his 13th Grand Slam at the US Open on Monday and still looked fresh despite the travel and playing two straight days. This is Nadal's first Davis Cup since 2011, and Corretja called Nadal's commitment to the team critical.
"Rafa's commitment to the team was critical and we have to be grateful for that," Corretja said.
Spain, a five-time champion, extended its unbeaten run on clay to 27 consecutive series.
