Not a player jersey, actually, but a couple of jerseys that Matt Williams wore in 2007, when Brett Butler had a stroke and Matty went out to Mobile to manage the BayBears for the last couple of months of the season. The white pinstriped jersey was gone by the time I heard about the sale, and Matty told me he took the red alternate with him when he left, but the team sold me the grey road jersey and the white vest-style jersey for $125 each, and Matty signed them for me at FanFest a couple of years later. I've got a lot of Matty's stuff, including five of his player jerseys, but having his first jerseys as a Manager is something special to me.
