Nathan was designated for assignment Friday, Carrie Muskat of MLB.com reports.

EDGE Analysis

The Cubs needed to clear a roster spot after activating Jorge Soler (hamstring) earlier Friday, and their recent additions to the bullpen made Nathan an expendable piece. Nathan had made just three relief appearances since Jul. 24 and none of those appearances were in August. He'll now be subject to waivers and could return to the Cubs organization if he goes unclaimed.
