Casting shows up in one number: hand path length.
Searched as "casting hands baseball". Here is what the phrase actually means, what the video shows, and how a measured report ends the argument.
What it looks like
- Arms push the bat away from the body early
- Barrel drags through the zone with no whip
- Gets jammed by anything inside
What is actually happening
Casting is the classic long swing: the hands push out and around instead of staying connected and letting the body do the work. It is one of the cleanest things a single phone video can catch, because hand path length relative to body height puts a number on it. A cast swing routinely measures far longer than it needs to be, and the fix is a task, not a lecture.
What we measure to find it
Every measurement comes from computer vision body tracking on one phone video, 33 landmarks on every frame, the same class of kinematic analysis professional organizations run on their players. Estimates are labeled EST, and no ball speed numbers are invented.
Drills that help
A bottle set inside the hand path punishes the cast route instantly and rewards the tight one.
Tee set deep, back of the plate. Driving that ball hard forces the body to rotate before the arms extend.
Drills are constraints, not lectures: set the task and let the player's body solve it. They work best aimed at the measured leak, which is the point of measuring first.
