Obstruction/Interference on same play

[Dakota]

Caveat: the OP was under (presumably) NCAA rules. So, speaking ASA

I submit that the note under ASA Rule 8-5-B does not apply due to context. Rule 8-5-B is not applicable to the OP situation. 8-5-B is concerning obstructing the progress of a runner or BR who is legally running the bases. The OP was the catcher obstructing the batter attempting to hit the ball.

The applicable rule is 8-1-D, which carries no exception for subsequent interference by the BR or anyone else. This makes sense to me since the presumption is the CO may have impacted the flight of the ball and hence subsequent play.

Therefore, I would rule the OC has two choices: result of the play (R1 out, BR on 1B), or the enforcement of the penalty (BR on 1B, other runner advanced in forced). I can guess which one he would take.
