The Ken Griffey Drill builds off the Launch Drill. The goal of this drill is to get into launch position through movement. This drill helps build good balance and rhythm in the body during a swing.
Ken Griffey Drill Instructions
Start in a tall batting stance
Start with the feet close together, hands relaxed around the bat and the bat in your normal slot.
Slowly take a step forward away from your hands and land in launch position. This is called walking away from the hands and this move should create separation naturally between the hands. Your goal during this step is to keep your hands in the same place as you step into launch position.
Once your body hits launch position, take a swing. If you landed correctly, you should be able to fire as soon as your front foot is planted. There should be no hesitation or reloading of your weight or arms before swinging.
