Certainly looks like a hand ball on the video replay.

Although the quality is bad. The kid reacted before the whistle so I think he knew it was a hand ball.

Tough call though. He certainly didn't gain advantage off it especially since it bounces right back to the Hilton Head kid.

That is why the pro's put their hands behind their backs when in the box. Last thing you want is to lose a game over and inadvertent hand ball in the box.
