As stated above, he will develop a little bit more in the next few seasons, but it won't be by leaps and bounds.
With his current ratings, I would have him at the below. This should improve a little bit as he develops, but right now he is simply underperforming.
In the AL:
Baa -- .266
Obp -- .348
In the NL:
Baa -- .256
Obp -- .338
