Cardinals designated RHP Guillermo Zuñiga for assignment.
This is the corresponding move for the Keynan Middleton signing. Zuñiga’s tough year saw him post a 7.63 ERA in 30 2/3 innings in Triple-A, get called up in late August anyway and then suffer a season-ending forearm strain in his second major league appearance. The 25-year-old Zuñiga throws 97-101 mph, so even with the injury and his history of control issues, it doesn’t seem likely that he’ll clear waivers.
