Will Nieves would be our backup catcher if we didn't sign a backup in the free agent market. Here are his stats:

He is 29 years old. Not really a prospect at all. Catching is one of if not our weakest position in the minor leagues. Our highest ceiling catcher in the minors is sixteen years of age and has never participated in a minor league game as of yet. His name is Jesus Montero, you may have heard of him. Obviously he is not ready for the majors yet. It's going to take him six to eight years to be ready, to be honest. He might even outgrow the catchers position altogether and be switched to a position such as first base.
