Mantiply was designated for assignment by the Yankees on Friday.
He spent just 10 days on the Yankees' 40-man roster after being claimed off waivers from Detroit. The 25-year-old Mantiply will once again be subjected to waivers and will likely draw interest from a few teams, as he's a lefty who posted a 1.24 ERA and 39:2 K:BB against same-handed hitters at Double-A last season.
