Wrist/Forearm exercises for pitchers???

[drc9805]

Are there any good pieces of equipment that strengthen the wrist and forearm? I know you can do wrist curls but I don't see my 12 year old doing those.

A set of soft weighted balls like in the following link can be used for a number of exercises. One can even use these as a portable Finch Windmill.
