We have Peguero, Hall, Herget, Yoho, and Misiorowski in AAA and Milner, Paredes, and Zastryzny on the IL. I'm sure there are a couple of MLB teams that would do a full swap out of their bullpen for that.
I wish roster expansion wasn't so stingy now. Just a couple more slots would do wonders for us. 40 may have been excessive, especially when we were actually carrying 37. Who knows what kind of crazy stuff could have been run out of our bullpen in September with a roster size that large.
