Hit by bouncing pitch...?

[UmpireErnie]

This is a big fastpitch mythical rule. The pitch is still totally alive if it touches the ground. If it hits the batter the batter goes to 1B assuming she tried to avoid being hit. The batter may also strike at a pitch that touched the ground, and if the ball is hit it is legal.

The only significance in the pitch touching the ground is that it can no longer be considered a “caught” third strike if it is swung on and missed. In LL Major and Minor groups (10U would have to be one of these divisions) the batter is always out on strike three so it would not matter for the game in question.
