Rafa Nadal is already in the quarterfinals of Wimbledon after beating Argentina's Juan Martin del Potro after nearly four hours (7-6, 3-6, 7-6, 6-4).

The next few hours will help determine what the consequences of the effort to Rafa, who played infiltrated by the problems in their knees and asked for medical assistance with a strained Achilles tendon.

Nadal was not to his surprise and came out determined not to give a single game with their service. Del Potro also grabbed his racket in force at the time of the first games out and fell on the side of each other quickly, without breaks.

A breaking point was the Achilles tendon Nadal when he stepped wrong after a stroke, which incidentally turned out to be a parallel right winner. That point gave him a chance to break 6-5 in their favor, but 'Delpo' came to rely on their service.
