VINA DEL MAR, Chile (AP) - After seven months away treating a left knee injury, Rafael Nadal has left many questions unanswered in his comeback tournament.
Nadal lost both the singles and doubles finals in the space of a few hours Sunday at the VTR Open in Chile. Horacio Zeballos beat Nadal in three sets for the first title of his career.
Nadal says the loss was a reminder of what he already knew. He realizes that returning to challenge the other three in tennis' top four - Novak Djokovic, Roger Federer and Andy Murray - will be slow and gritty.
