I don’t think they should trade any of the Catchers at the moment. Its bold to assume Moreno would make an instant impact at the Major League level. No reason to even touch him right now. Kirk is not only a competent Second Catcher hes our best option at DH at the moment. So trading from that strength for middle to back of the rotation starter sounds like a lateral move.
I would be much more interested in trading Moreno in a larger deal for a much more impactful player (star) considering the catching situation is already good. But I don’t see that kind of move happening.
