The Twins have signed Jason Bartlett to a non-roster deal, according to Jerry Crasnick of ESPN.com (via Twitter). Bartlett is represented by LSW Baseball, according to the MLBTR Agency Database.
The 34-year-old saw 29 games of big league action for the Padres in 2012, hitting .133/.240/.193 in 98 plate appearances. For his career, Bartlett owns a .271/.336/.366 across nine major league seasons. With the deal, Bartlett returns to the club that he spent the first four seasons of his career with.
The Twins also announced that Joe Mauer will transition to being a full-time first baseman in 2014. The move was made "after consultation with doctors from Mayo Clinic and team doctors," according to the press release. Moving Mauer, who is owed $115MM over the next five years, to first base opens up a starting spot for 24-year-old Josmil Pinto behind the plate.
