sub

[benbret]

NFHS girls varsity fast pitch. I am plate umpire 2nd inning visiting team DP gets a base hit single. Flex runs for the DP so the DP has left the game. 4th inning DP comes to bat but has not report back in. I remembered her. I ask her if she was re entering the game. She she that she was. Home coach was very upset that I had ask her. She though I should have waited and let them report that she was illegal. I explained to the coach that all she would have been was an unreported sub and there was no penalty. Should I have waited and let the home team tell me that she was an unreported sub or was I within my rights to correct it when I noticed that she was the batter?
