I think he will develop some power (20 HR), but why does he have to hit for power. Ichiro plays a corner OF, Tony Gwynn didn't have power, and Pete Rose played corner OF without power. When a team has a corner OF without much power, it needs to get power from non-traditional positions (2B, SS, CF, or C). Players like Arod at SS, Sandberg or Kent at 2B, Griffey, Mays, or Mantle in CF, and Piazza (in his prime) at C allow you to have corner OF without much power.
