Putkonen has been designated for assignment, Jason Beck of MLB.com reports. Putkonen was sent down primarily to make room on the 40-man roster for Tom Gorzelanny after he signed with the club on Tuesday. Putkonen struggled mightily in Low-A, Triple-A, and the MLB last season with a 12.15 ERA in the minors and 27.00 ERA in the majors, so he'll likely need to show some improvement before getting another chance with the big league club.
