The Rangers are petitioning MLB to allow them to extend Greg Colbrunn's rehab assignment because -- get this -- he hurt himself while rehabbing.
I've got an idea...why not release Colbrunn, and then sign him to a minor league deal, rather than keep him on the 40 man roster and beg MLB for more rehab time?
Seriously...the chances of Greg Colbrunn being claimed by some other team off of waivers right now is about the same as the chance that some team would have selected Agustin Montero in the Rule 5 draft...
