The Blue Jays designated Cuas for assignment Thursday.
Cuas will end up as the odd man out of Toronto's 40-man roster after the team claimed Emmanuel Ramirez off waivers from Miami on Thursday. The 30-year-old Cuas owns a 7.71 ERA and 1.78 WHIP across 16.1 innings between the Cubs and Blue Jays this season, and his minor-league performance hasn't been much better (6.67 ERA through 27 IP).
