Well, I think Kohlschreiber should certainly give a good test of where Andy is just now.
He's no mug on clay and beat Ferrero and Djoko on the way to the last 16 of the French Open last year.
So what sort of Andy is going to confront him ?
By the look of it, one who still hasn't sorted out his mental attitude: he's a break down already, *1-3! And beware the Germans. If he does emerge from the match the winner, he'll have to face Philipp Petzschner, who dumped out Melzer (15) by 7-6(2) 6-2!
