I am new here. If all is right and normal in the world Federer should prevail over Roddick easily. For me it would be devestating to see Roddick win with his rather boring clumsy style.
Roddick wins only becuase of his serve. Take that away and he is often reduced to counterpunching. He doesn't have the shot making ability to place a ball precisely and think on his feet shifting position automatcially with the fluidity that Federer has.
I hope Federer puts Roddick in his place because maybe then the networks will get the idea that Federer is the great player that they should be featuring in their prime spots.
