RKBUmp that is the call that needs to be made more often. I've seen the runner on third retreat, then lead off again all while ball is in the circle and everyone (including umpires) is so fascinated with girl streaking from 1b to 2b that they miss the violation on 3B. My girls have been guilty of this as well and not been called out, but the fact that they should have been called out usually results in a minor heart attack for the 3B coach who will specifically remind them that they LBR is in effect. That's the problem with confusion plays, sometimes you confuse yourself
BTW when I say ball in the circle I mean that no attempt to make a play is being made, so LBR is in effect.
