I'll add this..
Typically, this scenario, which has been talked about a zillion times, is discussed as a means of confusing the defense for some advantage for the offense.
But you have both your runner and retired batter at 1B.. thats fairly strange.
THere is definately no INT here, and you couldnt find a rule to justify whatever punishment you would like to consider for this play...
But yours isnt even worthy of a USC discussion because it seems the offense just stood around.
This sounds more like 16U church league low level play and even worse coaching - than anything regarding rules.
