Ideally, it would go down like this...
AO: Hewitt def. Murray 6-0 6-0 7-6(25)- Old people can win slams
RG: Clay GOAT Roddick def. Nadal 0-6 0-6 ret. Roddick comes out of retirement and gets to the finals of his best slam to play Nadal, and when Nadal starts kicking ass his knees start acting up and he is forced to retire
W: Volandri def. Ramirez Hidalgo 3-6 7-6 6-4 1-6 10-8 Battle of the grass legends
USO: Young def. L. Mayer 6-0 6-0 0-6 6-0 Young to go on a 65 match losing streak, only to break it by winning 7 matches at the USO including revenge from Winston-Salem vs. Mayer
I think this is likely, no?
EDIT: I choose viruzzz's predictions!
