Nishikori is a great talent but so unfortunate with those endless injury bouts.
Rafa has had to endure so many injuries in his career also. it is so damned hard to sustain high performance with injuries constantly knocking you to the ground.
but thank god he has been healthy this year. he has to realize the urgency of the matter now and go after 2016.
he still has it in him. we just have to see if he will do it.
