Is there a secret on how to counteract this pestilence?

From a correct Backstroke Top, do a ton of Start Down Waggles. I'm sure you can find a detailed description of this move in my Archives. Also, I demonstrate it in at least one of my videos, but I can't remember which one (I think it was in the Jeff Hull Series).

Most Roundhousers -- typically Slicers -- do not move to their left side, i.e., shift their Weight and slide their Left Hip slightly, adequately from the Top. Instead, they hang back on their right side and their Weight stays more centered. As a result, there is little Axis (spine) Tilt and the Right Shoulder cannot possibly move in its proper plane (toward the Ball).

So, give yourself a split second longer at the Top, and allow your Feet and Knees time to initiate the Downstroke 'Pull' via the Hip Action and Shoulder Turn. Your Hands will feel as though they remain at the Top. [During a lesson, I will often hold the student's Hands in place as he drills his Start Down Action.] Then, make sure you Pull your Hands directly toward the Ball and the Baseline of your Plane.

Remember, your goal is to swing down and out toward the Plane Line directly in front of you. That is quite a different thing than attempting to swing toward the target. Ironically, the oft-heard advice to swing 'toward the target' is the genesis of Roundhousing.
