Loup was optioned to Triple-A Buffalo on Friday.
Loup has been up and down a couple times already this season, recently being brought back up to the Blue Jays on July 2. During his time in the big leagues this season, he has posted a 6.00 ERA with a 0.67 WHIP during six innings of work, striking out eight batters but allowing two home runs. He has had a little better go of things in the minors, and will likely be back with the team at some point this year.
