If the Tigers do anything with Castellanos, it would likely be a promotion to Erie in the next 3/4/5 weeks instead of later in the minor league season.
Everything said about him is he has great hands that he trusts with his swing, has doubles power that will become more homerun power as he matures that is physically, third base play is good, but needs improvement with positioning of his feet.

Rebbiv posted this in the minor leagues thread. Mark has this site and also is at TigsTown, so if anyone knows the Tigers minor leaguers it is him.
and there are several other Tigers minor league followers who blog at various Tigers blog sites, that follow first hand visual, or word of mouth from scouts etc.
Personally, I don't think you can rush him, he needs more time, hitting, fielding, seeing better pitches and competition.
My interpretation, If all goes according to plan, is a 2013 September callup, and 2014 at 3rd, Cabrera and Fielder split 1B and DH.
