Ramirez was designated for assignment Saturday, Gordon Wittenmyer of the Chicago Sun-Times reports.
With Matt Szczur returning from the DL on Saturday, the Cubs needed to clear a roster spot, and they'll accomplish that by designating Ramirez, removing him from both the 25 and 40-man rosters. Ramirez will now be subject to waivers and will likely wind up at Triple-A Iowa if he passes through unclaimed.
