Lewis needs to eat a few more sandwiches before they get to fast-tracking him too quickly. Watching him from a fews rows back at Veterans Stadium, I could tell his physical maturity isn't exactly complete. Asking him to adjust to this and adjust to that in short sequences while also adjusting to his body filling out doesn't sound to me like the best recipe for success. Obviously, he's raking (mostly singles), but he's not the man-child that Harper was at the same age. (And I'm not trying to set Harper as a bar ... He's just an example of a young player that was physically mature at a younger age and was fast-tracked) I'm also not sure that his leg kick is going to be something that he keeps while moving through the system. It's pretty exaggerated. Every player is different, but it just doesn't seem like pre-swing movement that is going to work well moving up the ladder of competition. He's an exciting player, but I wouldn't throw him out in the deep end just yet.
