Rafael Nadal refused to get carried away after making his long-awaited return from injury in Chile
The world No. 5 joined forces with Juan Monaco as the pair claimed a 6-3 6-2 victory over second seeds Frantisek Cermak and Lukas Dlouhy in the first round of the VTR Open.
Nadal, who has not played since June after struggling with a knee injury, issued a word of caution ahead of his opening singles match against Federico Delbonis in Vina del Mar.
"It was a great feeling to play again and I'm very happy for doing it with a friend like Monaco in a great atmosphere that we had on the court," Nadal said.
"In doubles the effort is always less [taxing]; we will see how it goes in singles and how my physical condition is. I chose this tournament because it is the perfect time and surface."
