Usually, if they are moving guys around that low in the minors, it's because they are trying to find a defensive home for the player, not to make the player more versatile (ex. Justin Gonzales, Yoeilin Cespedes. Blaze, Brannon, Matthew Lugo). With Rafaela, they tried him in the OF to see what it looked like and he took to it almost immediately. From that point, he was like 75/25 CF/SS. That may be an exception due to his outstanding defense. Otherwise, they haven't gone in that direction from what I remember.
