THE 3 STEP delivery with slide is recommended. Take position ten to twelve feet behind the foul line. Start with your left foot and drop the ball down and away from your body.
THE START: Stand comfortably with foot opposite the throwing arm a foot in advance of your other foot. Face the pins and be relaxed.
THE FOLLOW THROUGH: The important factor of a successful delivery is a complete follow through with the hand and arm. Always keep with palm of the and wrist rigid.
As your right foot begins the second step, your right arm begins the back swing. Do not allow your eyes to leave the pins until completion of delivery. Make sure the back swing is completed before the second step is run through.
The third step is the slide and brings the body forward in a crouch as the arm begins its forward motion. Be sure the arc of your swinging arm is close to your body and that the hand is under the ball. Hold the wrist rigid and do not allow the arm to bend.
SLIDE: Your crouching momentum and fully extended arm brings your hand within a few inches of the floor. The extended follow through helps you roll the ball instead of lobbying it.
DELIVERY: Don’t release the ball until your arm is at the bottom swing. The ball should hit the lane six to twelve inches beyond the foul line. Be sure the arm is fully extended with no bend at the elbow and the ball is rolling off the finger’s tips. The value of the follow through cannot be overemphasized.
