Most of the videos of hidden ball tricks you'll see are from the Major League-level of baseball, but this one comes from high school ball and it's executed marvelously!

I reference the big leagues because most players who attempt the trick make a halfhearted attempt at selling it. This one I found on Youtube is Oscar worthy.

Per the video description:
