I would be in favor of bringing them up to get their feet wet. If they decide to move Santiago out of the rotation, whether it be back to the DL or something else, I'd like to see them bringing the kids up to fill that spot. It seems that Gibson is salvaging something, so I don't see them moving on from him yet. Any time a 5th starter is needed, I'd like that to go to one of the prospects too. Even if they're just getting spot starts at the big leagues, they're still being given a learning opportunity. There can't be anything wrong with that. They get a taste of what they're dream is and perhaps some pointers from the big league staff and/or veterans. In the meantime, if they're not on the major league roster I'd like to see them at AAA. I'm not sure they have much left to prove at AA. Get them some tougher competition to help reinforce the major league experience.
