To help your bunters keep from bunting the ball too hard or else pushing the bottom of the ball and popping up, try this. Teach your players to Reach Early and Catch Late. This means when your player turns into her bunting position (whatever type of bunt she’s doing), she’ll reach Out with her hands and the bat early and then catch, or give with the ball, late.
This helps her soften the bunt. What most bunters do is just the opposite. They bunt early, meaning they have their hands and the bat in close to their body when they first turn to bunt, and then catch late, meaning they try to get soft at the very last minute. Reverse the two by reaching early and catching Late and watch your bunting success improve!
