Runner on first, only one out. Batter swings and misses strike three. My catcher drops and blocks the ball. The runner at first has a little too big of a lead and my catcher throws to first to pick her off. The problem is that the batter is running to first and interferes gets in the way of the throw and the play. Base runner goes to third on the play.
I know that the batter is out, but what about her interference? She is not legally a runner since less than one out/first base occupied. Does the base runner go back to first?
Thanks
