Loup was optioned Tuesday, Shi Davidi of Sportsnet reports.
Loup appears to be shaking off some rust as he's given up three earned runs along with a blown save in three innings since his recall. While he's only given up three hits over that three-inning span, two of those have gone by way of the long ball. The 28-year-old reliever will likely head to Triple-A Buffalo now to sharpen up his mechanics.
