[Roger Federer]. As we speak, (new father, yet still very much a fox) Roger Federer joins Rafael Nadal, Serena Williams and John McEnroe at the pop-up regulation tennis court at 23rd Street and Broadway to show local youth players what it is like to hit the ball around with a real professional. This is also the debut for Nike's 2009 U.S. Open looks, so you can see what colors shall be gracing the courts not too long from now. Games start the 31st of this month.
