Some uppercut is correct. The measurements say how much is too much.
Searched as "uppercut swing baseball". Here is what the phrase actually means, what the video shows, and how a measured report ends the argument.
What it looks like
- Pop-ups and swing-and-miss under fastballs
- Big finish, little contact
- Chases the launch angle look without the results
What is actually happening
Good swings attack slightly uphill because the pitch travels downhill. The problem version pairs a steep barrel with a deep hand dip and late timing, and the difference between the two is measurable, not a matter of opinion at the fence. Before flattening a young hitter's swing, measure whether the uppercut is actually the thing costing them contact.
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
Top-of-zone tee work exposes a true excess uppercut immediately.
Reward the ball flight you want and the barrel finds the angle.
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.
