I think I asked this before but I remember there wasn't a clear answer. Some said it is interference by a retired runner, Batter Runner is also out, but some say the runner does not have to get out of the way, the fielder has to adjust her throw, therefore it is a live ball. I asked our rules interpreter about this play, he says where is the runner to go, she can't disappear, but I feel that it is interference, what say you?
