Don't worry, you're not the only one! The movement on clay is a nightmare for anyone who hasn't grown up playing on the surface, and that includes the pros even. I'm just glad no one has filmed my futile attempts at sliding around on the clay and probably looking retarded
Luckily nearly all fast carpet and hardcourt where I live though, where I'm much more at home!
But I could have the game to play very well on clay,I run very much and my game sometimes is just to keep ball in
On hardcourt I could go at the net often,although I'm not tall,I play good there
