Overthrow - how many bases?

I believe this is true for all levels, but not sure about FED, but I know that with OBR this is a 2 base award AT THE TIME OF THE THROW(the throw is considered as when the ball is released from his hand) since this was the second play by an infielder (the first was the play by the short stop)

Coach Solty,

In your scenario the runner is awarded two bases from the base occupied at the time of the throw. Therefor he is awarded third base. The fact that he was headed toward first base doesn't matter.

NFHS Rule 8-3 covers baserunning awards and there is a table on page 53 of the rule book that can be used as a quick reference.

There is one base award under NFHS (Fed) rules that is determined by the direction that the runner is headed. If a thrown ball becomes lodged in an offensive players uniform he is awarded one base beyond his last legally aquired base if he is attempting to advance. If he is retreating when the ball becomes lodged he is awarded the base to which he was retreating.

In all but one case it's one from the pitcher's plate and two from the field.
