Ousting Castro from the organization remains a head-scratcher for me, especially when he had options remaining and could have pitched in AAA if he wasn't ready to help the big club. The same was true for Tommy Kahnle, though the Rockies at least managed to flip him for a pretty good prospect.

It's frustrating to watch the Rockies let these young power arms go when 40-man roster crunch day comes, and they have personnel decisions to make. For some reason they extend roster spots to fungible players with no upside - such as Rafael Ynoa and Brandon Barnes, as recent examples - while giving up on players with a lot of potential. You can shake a tree and a half-dozen guys like Ynoa, Barnes or Alexi Amarista will fall out. Not so with guys who throw 99 mph gas out of the pen.
