She said ???This match would be going a lot differently if it were held on grass, where Roddick???s serve would skid.??? Putting aside for the moment Federer???s 47 match win streak on grass, in addition to the nine out of ten sets Federer has taken off of Roddick at the All England Club, Federer beats Roddick on hard court, grass, clay, quicksand, water, ice and any other surface.
