Actually that is the exact reason the night matches will suck thru Monday. CBS has first dibs. Why else do you think Fed-Hewitt is on at 11AM? If that match took place at any other time besides the middle weekend, it would be a night match. Same for Roddick-Isner. I'm sure CBS even had a hand in determining which side of the draw played on each day. As of now, they get Roddick/Fed/Sharapova on Saturday and Monday, while the Williams Sisters take over on Sunday.
