In this article we will show why hitting drills that promote a linear (A to B) extension of the hands can not increase bat speed. We will further show that taking the hands in a circular path induces a "Pendulum Effect" that does increase bat speed. This is one of the reasons why the Rotational Swing Model is far superior to the Linear Model.

However, for decades nearly all batting instructions, whether taught by coaches or described in books and videotapes, were based on a "Linear Swing Model." By linear, I refer to the concept that bat speed is derived from the batters forward weight shift and extension of the hands. Liner coaches use cues like: "The shortest distance between two points is a straight line", "Drive your hands (A to B) and "Throw your hands or knob of the bat at the ball."

As the video below shows, none of the linear cues mentioned above will help a batter maximize their bat speed. To maximize bat speed, the rotation of the body must propel the hands in a circular path. A CHP will induce the "Pendulum Effect" that accelerates the bat-head around the swing plane. This is a key component of a "Rotational Swing Model."

(CHP) Circular Hand-Path vs "Extend your hands (A to B)"

An 'overhead' view of the hand-path of the best hitters clearly shows they do not extend their hands in a linear (A to B) path. Below is an overhead view of Pete Rose's swing. His hand-path is representative of what you find with all the best hitters.

Conclusion: Practicing drills from a linear model will not allow you to maximize your bat speed. To reach your full potential at the plate, you must practice the concepts of a Rotational Swing Model.
