2012 US OPEN: Bottom men's draw/ Predictions?

We have Tipsarevic vs. Ferrer for the day match and the night match we got Djokovic vs. Del Potro.

I am going to go with Ferrer and Djokovic. They just have more "dimensionality" to their game. I made up that word but what I mean is they have more angles, better returns, and stronger rally potential.

Unless Delpo can hit through the court and make Djoko run on his heels or Tipsy turns on the flat groundies a dial, I see it my way. How do you see it?
