OP is not getting his answer - but that is because the umpire did not make a proper call. We don't know how to score this, since it shouldn't have happened. But ... since it did happen, I suppose the only way to treat this would be the same way you might treat it if ODB did actually come to bat, and then interfere with a play before his AB was over. F2 gets a putout. ODB gets an AB.

Now back to the sitch... there is no rule by which you could call ODB out. Even though Rich's definitions are correct and make more accurate the post before his, the ODB is still not a batter in this sitch until the previous play has come to completion. He is merely a member of the offensive team that is legally on the field.

You can't have an out for interference unless someone interferes WITH A PLAY. There is no play here (yet). The ball is dead when he picks it up, obviously, so no play can eventually occur. Had BR rounded first on his way to 2nd prior to this ball being picked up, I can see a case for INT on an offensive player --- but it would be the RUNNER who would be called out. If there was an additional runner for which a play was possible (say someone else trying to advance on the PB), we could have INT - but again, it's the RUNNER who is out. ODB still comes to bat after either.

On this play (assuming no other advancing or in-jeopardy runners), I have dead-ball and nothing else. BR to first. ODB to the plate.
