Any of Tonkin, Wimmers, and Baxendale could be sent to AA, based on middling AAA performance alone not to mention lack of a future in the org. Nobody has to be given walking papers yet, if there is any concern about losing minor league depth or filling the vacated AA spots. (Mickolio would be another option for demotion, although I'm guessing we promised him a longer leash?) On the starter side, now that we've added Melville, Heston, and Wilk to the AAA starting ranks since the season began, Pino and Tepesch could be near future releases if we want too (assuming they don't want to be sent to AA, or we have better replacements in mind for AA). Most of these guys will be minor league free agents at season's end anyway, except Baxendale. (I'm assuming Wimmers gets removed from the 40-man again by that point.)
