Marat can beat Del Potro, I reckon.
Ascione is dangerous, big underachiever, big game. Hopefully he doesn't catch fire.
I agree with the first statment - Marat has a better all around game then Delpo - but he can only win if he believes in himself.
I don't know Ascione... I'm sure he is a threat - I just really, really, REALLY hope Marat doesn't make losing to him the last match of his career... quite frankly, I could handle him losing to Delpo more than I could Ascione...
