look back rule

[Cecil4]

Thank you for the welcome and both comments, Steve.

My OP is what one of our umpires called, told him it was correct, but sharing it.

A somewhat related real play:

R1 on 3rd, batter walks. No, not the same play.
F2 tries a pickoff of R1, becomes a run down. R1 slides into 3rd, barely safe.
R1 is prone from slide, fielder still holding attempted tag, so R1 asks for and is given time out. Near the end of the run down, R2 realized she should have gone to 2nd; starts and stops, returns to 1st.
Defensive team wants a Look Back out for R2 leaving 1st because the fielder with the ball at the end of the run down was the pitcher. Had to explain about not in the circle.
