Rafael Nadal had landed in Cordoba for Spain's Davis Cup semifinals and is still tired after his failed US Open campaign.
"I am tired," he told DavisCup.com. "I played very long match and for sure it is a challenge for me. I am trying for my country but it's tough. For me it's not a mental problem, it's a physical problem. I am ready to play mentally, but physically two and a half weeks was hard."
