Ensberg seems to fit the mold of the Carlos Pena and Eric Hinske signings.  Career .830 OPS, .912 v. left-handers, has had a few good years, but recently a few bad ones.  Could he be the guy the Rays sign to a minor league contract who resurrects his career with a big year? 

Also, the Rays have 3 open spots on their 40-man roster, in addition to guys like Jason Hammel and Jae Kuk Ryu who don't have any options left and probably won't bee on the team on Opening Day, plus Jake McGee who will be placed on the 60-day DL, leaving us with 6(!) open spots on the 40-man roster for Opening Day.  If we assume the Rays sign a full-time DH, then there are still 5 spots.  My hope is that Andy is going to invite a lot of players (Ensberg, Rheinecker, etc.) to minor league deals with invites to ST who have a real chance to have an impact.  This is especially relevant for relievers.
