The Sickest Hidden Ball Trick, Ever
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 executive 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:
