Buy red, white and blue wiffle balls. The plan is to train the hitter to see the ball better and that will mean longer (essential skills for hitting off-speed pitches) Inform the hitter that the red ball is to be hit hard to the correct spot (inside pitches are pulled, etc). The blue ball is to be bunted and the white ball is a take.
I think you will be surprised at his pitch recognition after only 4-5 practices.
This is also a good indoor practice.

Be cautious of doing color drills in which you train your muscle memory to "take" strikes that travel through the hitting zone. However, we love the color drill too! Watch an MLB demonstration of the drill by visiting our website: www.BigLeagueEyes.com
