I think this is a good move. Arcia's injury isn't a major one and he'll probably be ready after 2-3 weeks. So why not give Eddie Rosario a cup of coffee and see how he does in the majors? He'll probably end up getting shipped back down to AAA when Arcia's ready, but that's fine. Rosario could turn out like Santana and Vargas and force his way onto the roster - and that'd be fine, too. I guess for Hicks, when he comes up, it's time he stays up. I see him replacing either Robinson or Schafer, and if one of them are DFA'd, they may not make it through waivers and we'd lose a little depth, meaning that Hicks would need to play well enough to stay on the major league roster.
