This is why I have issue with adding a guy to the 40 man to promote him for one start, or a week of ABs (I'm looking at you, people suggesting we bring Pillar up...) The 40 man roster can quickly become a mess that way.
Frankly, moving Oliver should be a no-brainer (even if we were buyers, 4 lefties in the pen is unnecessary and you can probably get a semi-valuable piece for Oliver in addition to clearing a spot on the 40 and 25 man rosters). Loup and Wagner have been great, but both have options. Redmond will obviously be going down...
I would be truly happy if the Jays could get ANYTHING for Bonifacio, I hate losing assets for nothing, but it's very hard to call him an "asset" anyway.
I'm not terribly concerned about making space for Melky, as I think an extended stay on the DL would be the best thing for him (and the team). He was not very good over the last month+, and much of that can be attributed to his bum legs (and possibly his "nah brah, I'm not on roids!" thing...)
