The point is that unless they do a complete 180 on Alcantara(and he starts hitting at AAA) or Baez gets healthy, the only true alternative to playing Castro everyday is Herrera. Sure there's some probability that Herrera might be better over a short stretch, but it's a move with no upside that bottoms out Castro's trade value, all for the (some might say slim) chance that Herrera nets a couple run improvement over whatever Castro gives you ROS. There are no other real options to playing Castro. i agree that there are no internal options right now, but i think i'm past worrying about castro's trade value at this point.
