quote:7.10 b (2) When the ball is dead, no runner may return to touch a missed base or one he has left after he has advanced to and touched a base beyond the missed base.
a. When the ball is dead
...the ball 'went dead' when it left the fielder's hand on the throw..at which point the runner was between Second Base and Third, and had missed Second base.
b. ..after he has advanced to and touched a base beyond the missed base
...he has not touched a base beyond his missed base (which was Second). He is between his missed base and the next base (Third). Therefore he can correct his missed base *if* he recognizes his error. The rule says clearly "or one he has left" which in this case is First. Therefore, if he stops between Second and Third and thinks, "oh no, I missed Second and left First too soon!" he can go back to Second, touch, then First, retouch, and move to Third on the base award touching Second on the way. He has now completed his baserunning responsibilties and an appeal would be denied. If he doesnt realize he missed anything, and just goes to Third directly without retracing his steps..then on an appeal he is out.
If he touches Third, then he cannot correct his error. Of course, if the defense does not appeal, then he's ok anyway.
I dont know how else to say it.
