How can his serve let him down on HC, his serve is his biggest weapon, I don't get how some tall players like him do well on it, as their serves are less effective usually, Milos and Isner being 2 exeptions, in the past big guys have never done well on clay, why is it so now.
Marc Rosset did well on clay. The Poo had some excellent results on it. Kuerten was tall, the clay didn't bother him did it?
Good serve works anywhere, the height they have can create the angles and the right amount of spin the clay will help that, just basic stuff.
Rosol feels more comfortable on clay in all facets and on grass it's all about his return and movement.
