We actually teach them how to get hit and call it fear of the ball drill.
When they think they will get hit, they turn their back to the ball and twist the hips and feet rearward and tilt the bat head downward.
We take a ball and start from the ground up and touch the back of their leg with the ball and point out the knee caps are not going to hit and basically it is the fleshy areas that will be hit and that is a bruise verses a broken bone. Back of thigh, butt, back and shoulders. Then we point out because the bat is tilted down it tucks the elbows in and the fingers are protected by the rest of the upper body.
We point out you can play with a bruise but it is very difficult to play with a broken finger, elbow, knee cap, wrist or ribs.
Many times when you see a hitter bail out they stick their butts out and think that will help until you point out the ribs, fingers, wrist, elbows, knee caps and ankles are more at risk.
Now they set up off the plate and I throw tennis balls at them as they practice their turn. I have found when you explain the results of not turning they become educated and seem to understand and I would not say accept liking to get hit however they have a better understanding of how not to and minimize the potential injury.
Why does the helmet have a cage? Why do you use a glove verses bare hands to catch a ball?
The kids are not as stupid as some may think and logic and examples will work with most of them, depending on how the message is delivered in my opinion.
