The DMN blog says Eddie Guardado has been dealt to the Twins, but no details...

 UPDATE -- Not really an update, but it occurs to me that, unless the Rangers got an arm back from the Twins who is going on their 25 man roster, Texas will need to add a pitcher.  Maybe Bill White, if they want to go lefty.

 UPDATE -- From T.R. Sullivan:

The Rangers are getting Minor League reliever Mark Hamburger in return, a decent prospect. Bill White is being called up to replace Guardado
