The current rosters stands at 24. The A's sent Braden down yesterday and have yet to assign a replacement to his roster spot.
Is it possible they are working on a "Cust-like" trade for bullpen help?
I'm guessing if they were going to promote someone from the current 40-man roster they would've done so by now. I'm also guessing that they are not too impressed with the likes of Windsor, Komine, Meyer, Casilla, and Shafer.
One rumor is that they may promote Colby Lewis, who is having an outstanding season so far for Sacramento. If indeed they promote Lewis, they're going to have to release someone from the 40-man roster. Options include: Santiago Casilla, Jeremy Brown, Donnie Murphy, and Bocacahica. Another option would be to move someone from the 15-day DL to the 60-day DL, those candidates include: Harden, Street and possibly Snelling.
