Veteran first baseman Sean Casey is retiring from baseball after 12 years in the major leagues. Casey played for the Red Sox in 2008, but is best known for his time with the Reds, where he earned the nickname "The Mayor" for his genial and friendly nature in the clubhouse and at first base with opposing baserunners.
Casey was never the prototypical slugging first baseman, but he made up for it with a solid glove and a career .302 batting average. He's almost certainly not going to be the only experienced free agent to be forced into early retirement because of a lack of interest this winter, but he is one of the first noteworthy names to hang 'em up.
The good news? Casey will take his considerable good guy talents to the brand new MLB Network, where he'll join Harold Reynolds and company in their so far successful attempts to make John Kruk and the rest of ESPN's Baseball Tonight crew obsolete.
