The Cubs made an under-the-radar procedural move Friday that should factor in a more significant way within the next week or so, as righty Edwin Uceta cleared waivers and was assigned to Triple-A Iowa. That gives the team three open spots on the 40-man roster, one of which will go to Jordan Wicks once he’s officially added. The other two will go to Pete Crow-Armstrong and possibly Luke Little or Shane Greene, though there are a number of other relievers waiting on the 60-day IL.
