Because of the new ranking system, all of the tourny's Delpo won before the US Open will lose a few points except for Washington. Because of this Del Potro loses a minimum of 700 points before going into the US Open and that assuming that he defends all of his victories by beating Roddick in LA and Washington. If he fails to defend Washington he loses another 200 points. So the race for #5 in the world comes down to how well Del Potro defends all his tournaments and even then if Roddick does better than him at one of the masters events and ties Del Potro at the other Roddick becomes the new #5. It becomes even easier for Roddick if he beats Murray but beating Murray will not be easy. Del Potro has a long summer ahead of him.
