[ronald]

It states that the runner may not return to touch a base left too soon or a missed base once the runner has advanced to the "next awarded base."

So if batter runner misses first base, between 1b and 2b when ball leaves fielder's fingers and on 2b when it goes out of play, what is the ruling? Has he already advanced to the next awarded base (he/she will be awarded 3b and is on the next awarded base. That is what I understand at this point) or can he go back and retouch?

In Federation he/she is SOL.

Thanks.
