Mayer is probably three seasons away, but Rafaela looks like the real deal. Saw him play SS this summer and he made some great plays, and they say he is even a better CF. That is where I see him for the Sox in the next couple years. Solid with the stick as well. Cases I think will be OK with the bat, and his D is great. York and Bleis are too far away yet. I hope Bello and Mata are the real deals.
