Federer nets new best friend

ROGER FEDERER and Tiger Woods broke open two bottles of Dom Perignon and toasted — to a growing friendship, greatness and Grand Slams.

With his new best pal watching from a corner box, Federer rocketed a final forehand past Andy Roddick, fell to his knees, then flopped onto his back. He’d won his third straight US Open title in convincing fashion on Sunday: 6-2, 4-6, 7-5 and 6-1.

When it was over, Federer returned to the locker room, cracked open the champagne and spent an hour with perhaps the only other athlete who understands such sheer domination.
