Twins signed RHP Rich Harden to a minor league contract.
He's been given an invitation to spring training. Harden missed the entire 2012 season following surgery to repair a torn capsule in his right shoulder, but he's reportedly healthy now and trying for a comeback. The 31-year-old hasn't had any success since 2009 and has, of course, had major problems with staying healthy, but it doesn't hurt to see what he might have left. The Twins aren't sure whether he'll be used as a starter or reliever.
