I'm not sure if I am thinking straight, but as of late the Knights hae been putting Burke at 3rd more and more and opting to let Casanova catch. Of course, if Burke was to be called up, it'd be interesting to see who'd be catching for the Knights. Casanova can't do it every night, so possibly Davis would come off the DL or Rosa would be called back up. I don't see Aceves or Stewart being promoted to AAA, just because.
