I am not even sure what Rafa is doing here in Miami.
he should have lost to 35 year old stepanek in his very first match in Indian Wells. he is playing horrible tennis.
I am sure it was because of the commitment he made to them (Miami Masters). and also the huge appearance fee.
he did not serve for 10 days after Rio. I think he goes out pretty quickly in Miami at the rate he is going.
he needs to go strengthen his back and also get on the red clay ASAP.
