Where did the OBS occur?

Sounds like a league ball game. Reading through the ASA rule book concerning this issue and applying to this situation; I agree with returning the runner to 1st base. Although I would not make this a normal routine. In my opinion coaches will continue to send the runners onto the next base merely because the fielder is standing on the base.

And why shouldn't they? As long as 1B continues to obstruct without penalty, you are rewarding that obstruction. The defense deserves the appropriate penalty; they lose the right to put the runner out between first and second when 1B stops BR from making a turn.
