Hamilton had only played three games in his rehab stint before coming back to the majors, so it's completely possible that he is simply not ready yet. With the Reds being well out of contention, it's important to develop players for next year, and Hamilton needs that developing.

He does still have 54 steals, but it's hard to imagine what he could produce if he could push his on-base percentage above .300.
