Interference BR - Base on Balls

[JPaco54]

OBRs - No outs. R1 on 2B...3 balls on the batter. R1 stealing on the pitch. Ball four. F2 throwing to 3B and is interfered with by the batter(Batter Runner). HP ump called interference on the batter (BR). He awarded the BR 1B and called R1 out...I questioned the call in my mind and thought that the BR should be out and R1 returns to 2B...There was no agrument from either HC's on the call other than the Offensive coach did not think his batter caused interference.

Two innings later I approached my partner between innings and state that I think we got the call wrong as far as placing the runner. I told him that the BR should be OUT and R1 should have been placed back on 2B. He thought a moment and said that he remembered that if there were two outs then the BR would have been called out.

I referrenced my Jaska/Roder manual last night and got more confused. Appreciate advise on clarification. Thanks!
