there is no question in my mind that hard courts are brutal for nadal general masterclass.
in fact it is the hard courts that have led to almost all of his injuries. he was tired which led to straining the back.
he had already won 10 tournaments and took home 2 slams in 2013 but the quest to go after the #1 rank also cost him some much needed rest and recovery.
and then there was that south American exo tour that had to take its toll too. he was not home much at all for his rest and recuperation and some training.
tour is very demanding now and the top players need more rest than the others since they are the ones going deep into all the tournaments and winning majority of them.
excellent news about andy murray. he is progressing well after the back surgery.
