The Cubs reassigned Adduci to their minor-league camp Saturday, Jordan Bastian of MLB.com reports.
Unless he requests his release from the organization, Adduci is slated to open the season at Triple-A Iowa. The 33-year-old has appeared in 88 games at the big-league level with the Tigers the past two seasons, but his status as a non-roster player in addition to the Cubs' wealth of intriguing bench options will make resurfacing in the majors an uphill battle for him.
