Has Mike made his final Moose call?

Many reports have announced (Ken Rosenthal being the 1st) that Mike Mussina will retire as soon as tomorrow. Mussina, being my favorite player, and the most important reason for the yankees coming close to making the playoffs in 2008, will go out on top with a 20-win season. This was expected, but I wished it wasn't so. Mussina is a possible hall of famer.....he will be missed.
