This very rule came up for at our HS Association meeting tonight.
It turned out that no one argued that there was no coach option.
The new twist (to me) was that many argued (reasonably) that since the ball became dead "at the end of playing action", a runner going from 1st to 3rd on a passed ball, should be allowed to stay there - and a ball awarded to the batter!
Conversely, if she was thrown out at 3rd, the out would stand and a ball would be awarded to the batter.
The thinking here is that similar to obstruction, she is awarded 2nd but whatever happens after that, happens..... And at the end of that playing action the ball is dead.
Hmmmmmmmmmmmmm

Sounds similar to another sport - just can't remember the name
After much discussion, our rules interpreter was tasked with getting the FHSAA interpretation. Hopefully it will match NFHS.
