Monroe, 30, hit 28 homers and drove in 92 runs for the Detroit Tigers in 2006 and tied Hank Greenberg's franchise record with five postseason homers. But he slumped to .219 with 12 homers and 59 RBIs for Detroit and the Chicago Cubs last season.
Minnesota acquired Monroe from Chicago for a player to be named on Nov. 13. When the Twins picked up left fielder Delmon Young from Tampa two weeks later, it appeared they wouldn't have enough at-bats for Monroe and might non-tender him by Wednesday's deadline -- thereby rendering him a free agent.
But the Twins ultimately decided they have enough at-bats available for Monroe between the outfield and designated hitter to warrant re-signing him. Minnesota currently has Young in left field, Michael Cuddyer in right field and the left-handed hitting Jason Kubel as its primary designated hitter.
