The Rangers have outrighted Kevin Gryboski and Michael Tejera to AAA, removing them from the 40 man roster.
From the standpoint of them going to AAA, this is strictly procedural, I believe...I think both players have the right to be minor league free agents at season's end, since they are no longer on the 40 man roster.
Mainly, this is just a matter of clearing out some deadwood from the 40 man roster in advance of the numerous moves that will need to be made this winter.
