This is my interpretation after scouring the NFHS rules too but I have the question in to the head of my association as well. In fact, this was a 14-year old who meant no harm by touching the ball but just did a dumb thing because, well, he's 14. He simply meant to return it to the pitcher for the next play. Add to that the ball was moving so slowly, all runners would have been safe had the ball rolled back fair by some strange act of nature. I'm more comfortable this was called correctly than I initially was.
