2009 Official Rawlings Major League Baseball - Minnesota Twins HHH Metrodome. This ball is from the final season of the Hubert H. Humphrey Metrodome in Minneapolis, MN, former home of the Twins and Vikings. I cannot confirm this ball was used in a game, but from the scuffs it appears to be game-used or at least batting practice. Great piece of Twins history for your Fan Cave.
