To be honest, I think if they want to get anything out of Gose, he should be in the majors. I feel like he's going to go down and sulk and spin his wheels and waste another season. At least in the majors he provides legitimate contributions defensively and via pinch running. Hopefully, the light goes on with the bat. That's not to defend him being a sourpuss, but just seemingly the reality of the situation.
If the team is trying to take "the best team" north, I'd probably have Gose on it.
