He is just simply the come back kid of all time. I mean the bottle the guy has to come from being No 1 and in the exalted company to playing a challenger in Las Vegas. He decided he wanted to be the best, and the best he was. His powerful ground strokes made the base for his game and he has led the way forward to a new generation of power tennis. The fans love him. And he will be sorely missed when he eventually retires. He has been good for tennis and it has been good to him, I wish him well in the future.
