Little League: Challengng a Tag Up - is this a force out

Question
The below question was submitted by someone else.  I was reviewing the Q&A's and come across this one.  You answered that the appeal was a force out and the run would not count.  I believe once the ball was caught by the second baseman then the force was removed.  The defense now has to appeal that the runner left early.  They did not lose their appeal due to the overthrow since that was part of continuous play, but once the ball was retrieved and the first baseman (assuming) stepped on first base the runner would be declared out on appeal.  However, since this is not a force out you would have a timing play and the run could very well count.  In this instance I believe it would.  Can you clarify your response since you were short on time?

Question
Hi,
I have Little leauge question in regards to tagging up. Here is the situation - player on 1st and 3rd with one out. Line drive is hit to the second baseman who catches the ball. The second basemen then throws the ball to 1st to try for the double play (the 1st base runner took 5 steps off the base). The ball is thrown over the head of the 1st baseman and out of play. The runner on 1st is on his way back to 1st when he sees the ball is caught, he then sees the over throw, turns around without tagging up at 1st and goes to second base. In the meantime the runner on 3rd tags up and runs home. The other team challenges the runner on 1st not tagging up and the coaches agree he is out for not tagging up. The controversy/question is does the run scored by the player tagging from 3rd count as he scored before the challenge was made?


Answer
In the question it was stated that the runner on first took 5 steps off the base. I assumed that to mean that the lead that was taken was 5 steps off the base. If the runner was off the base the entire time of the play then no appeal would be needed.

If they were challenging that the runner left early then you would be correct. In the 6th sentence it says the runner sees the overthrow and without tagging up at first runs to second.

I probably should have asked for more information on the play so I could give a better and more clear answer.
