One great way to maximize benefit from a bat is to adjust the hitting surface. Meaning, use a bat smaller in diameter than a game bat. Minimize the hitting area of a bat, and force a hitter to strike the ball with a smaller “sweet” spot. This develops great vision and excellent tracking skills, plus enhances hand-eye coordination.
There are commercial and trademarked smaller-diameter bats available. An inexpensive way is to craft your own using a shovel or post-digger wooden replacement handle available at most lawn-and-garden stores. Cut to an appropriate length and, for an approximate $5 to $10 investment, you have a sturdy, resilient, long-lasting and useful bat. Get a handle on greatness and use this type of bat.
