More velocity/control from slide step than with leg lift

14U player shows more control and velocity from stretch with slide step than wind or stretch with knee lift.

No velocity numbers to back up, will hopefully have numbers soon but is pretty clear visually when watching throw. First thought was his front side opening up so we’ll work a bit on making sure he stays closed but looking for any other ideas.


Often times when using a slide step the pitcher will do a number of things better.

  1. Get into a better hip hinge, and ride it longer into and until rotation (as well as getting into glutes vs. quads)
  2. Provide better direction towards home
  3. get better momentum down mound since they aren’t “getting to balance point” then having to start over
  4. throw with better intent because they feel they haven’t gotten all the benefits of a full windup

be careful about “staying closed”, you have to open into foot stabilization (when front leg braces up your hips should be fully open), often times pitcher never get fully open trying to “stay closed”. Just make sure the trunk hasn’t come along with the hips.

The leg lift when properly executed provides a moment of inertia from which one converts to angular acceleration (as the leg is lifted and first kicked out and then pulled in as the body rotates through). This is based on the Conservation of Angular Momentum. You can believe whatever you like, but the physics speaks for itself if one is willing to listen. BTW: Denny McLain had a leg-kick from the right and Vida Blue from the left that you might like to try and prove my point.


Here is how it works Kinesiologically.

The ball can not make forwards math until the Humerus is fully outwardly rotated.

This is the point when lengthening ends and shortening starts. lengthening ends long after leg lift and drop in where the body comes to a complete stop eliminating all previous forwards momentum
(no forwards math there) at that point.
Because our bodies work off the walking response, the glove side leg has to establish ground stabilization to even start the shortening process signaling and only after the Humerus is fully outwardly rotated. When using the traditional Humeral/Forearm transitional timing to length, your Humerus is much later in achieving outwards rotation to length, meaning any forwardness before that is wasted into the ground as heat, it is why you see ground piled up towards home plate instead of second base where it should be like coach Newton teaches us.

In the future when everybody finally understands this you will see the pitchers facing the batters with their feet directed forwards the way we are built to motor forwards. Pitchers will stride shorter, stay taller all the way through the delivery and recovery by rotating fully 180 degrees.

It has already started but because info is delivered from the top down (I must see a MLB pitcher do it first) it will remain secretive and slow to recognize by the bottom uppers.

Go ahead and start from the stretch, there is no advantage in all the leg lift motions that are taught now. Have him turn his ball side foot towards home plate

Hopefully High school and College rules regulators will go back to original baseball rules instead of their useless efforts in the last few years that limits foot positions that cause Knee and hip injury!
