What it is
The bottom/front hand pulls the knob as hard as the hitter can, throwing the knob to the ball. Once that action begins, the front hand and the knob do not stop — they stay in constant, fluid movement through extension and the follow-through.
Why it matters
Pulling from the elbow to the hand with the bottom hand generates as much bat speed as you can. The hands start the swing, and the hands are actually what turns the body — not the other way around.
What to look for
The knob moving to the ball and never stopping. A stopped front hand/knob is a strong tell the hitter went out to get the ball. Not a tug-of-war: the body should not be what pulls the hands into the swing.
How to do it
Pull the knob as hard as you can from the elbow to the hand, throwing the knob to the ball. Keep the front hand and the knob moving through contact, extension and the follow-through; they never stop. At the same time, the back hand throws the barrel to the ball. Let the hands start the swing instead of using the shoulders or the body to drag them. The Knob-to-Ball Dry Path and Front-Hand Whip drills train it.
What good looks like
The knob moves to the ball and keeps going. The hands work on their own instead of being moved by body momentum, the barrel gets to the ball instead of dragging through the zone, and the contact is hard.
