Craig Hansen called up

The Red Sox called up Craig Hansen to take Moss' roster spot. My guess is that they added another reliever, instead of a hitter, because Delcarmen has been struggling lately, Hansen has been pitching lights out at AAA (11 games, 16 2/3 IP, 17 K's, 5 BB's, 1.62 ERA at AAA Pawtucket), and the fact that, despite the stats, the Tigers have one of the best lineups in baseball right now, and the added arm could be useful in a four game set against such a powerful lineup. Not to mention the fact that they don't really have any outfielders at AAA that would be a decent Major League fill-in, and the only Major League quality batter at any position, in my opinion, is 1B Chris Carter.
