It's been pretty easy to see all year the improvement in his game with all the hard work he's put in (lost 15 lbs and is in better shape than he's probably ever been in) and with his new coach, Larry Stefanki. Glad to see it paying off for him, and glad to see him finally for the first time in his career actually listening to a coach and not saying screw it I'm doing it my way. As much as I like Federer, I'd love to see Roddick pull the upset tomorrow.
