The Blue Jays announced Tuesday that they’ve designated left-handed reliever Zac Rosscup for assignment in order to open a spot on the roster for right-hander Justin Shafer, whose contract has been formally selected from Triple-A Buffalo.
It appears that Rosscup’s tenure with the Jays will be a brief one. Toronto claimed him off waivers from the Mariners last week, but he appeared in just two games. In that time, he was knocked around for four runs on three hits and a pair of walks with two strikeouts in an inning of work. Rosscup had previously notched a 3.21 ERA in 14 innings with Seattle, but he also walked 14 hitters in that time. Rosscup’s huge swinging-strike rate on his slider and his general knack for missing bats have stood out over the past two seasons, but this year’s control troubles are also quite pronounced.
The 26-year-old Shafer will be stepping up for his second stint with the Blue Jays, who selected his contract last August but later outrighted him off the 40-man roster when he cleared waivers. He’s allowed just two earned runs with a 16-to-6 K/BB ratio in 18 2/3 innings for Buffalo this season.
