"Probably after losing the second set, mentally I lost my concentration," Nadal said. "The negative thing is I lost. The positive thing is I have few days off and can stop a little bit mentally. I can be a little bit more relaxed, because every day I play with pressure."
After an exchange of breaks to start the second, Tsonga broke again to lead 5-4 and served out the set.
In the third, Nadal missed a critical forehand volley at the net on game point and the fifth-seeded Frenchman went on to break for 1-0. An inspired Tsonga dominated the rest of the match.
