Fig. 1 - Positive and Negative sides of the ball
Fig. 2 - Positive Axis Point (PAP) for a right hander

A bowler's Positive Axis Point (PAP) is a point on the surface of the ball that is the positive end point of the bowlers initial axis of rotation.

Fig. 1 shows the Center of Grip, Grip Centerline and Grip Mid line, as well as the Positive and Negative sides of the ball, for a right hander. Left handers would be a mirror image of the one seen in Fig. 1.

The PAP is usually expressed as a pair of numbers, showing the PAP's offset from the Center of Grip, e.g. 4.5" over, 1.25" up, or 4 1/2" x 1 1/4" up, as seen in Fig. 2. The first number represents the horizontal offset along the Grip Midline, while the second number represents the vertical offset along the Vertical Axis Line (VAL). So, using 4 1/2" x 1 1/4" up, we know that this bowler's PAP is located 4 1/2" along the Grip Mid line and 1 1/4" up the VAL.

The PAP is instrumental in laying out a bowling, as it serves as the point of origin for the layout.
