Baserunning question - little league

[Manny A]

Just to add, OBR (from which LL rules are derived practically verbatim) says the following under rule 7.09(e):

"[A runner commits interference when] Any batter or runner who has just been put out, or any runner who has just scored, hinders or impedes any following play being made on a runner. Such runner shall be declared out for the interference of his teammate;
Rule 7.09(e) Comment: If the batter or a runner continues to advance after he has been put out, he shall not by that act alone be considered as confusing, hindering or impeding the fielders."

So, just because R2 continued to run after scoring here, that, in and of itself, is not interference, per the Comment. He had to have hindered the defense while they made a play on R1 or the BR, which is not what it sounds like happened here. The defense should know that once R2 scores, he is no longer a runner, and they should ignore him.

It's no different than when a batter takes off for first base on an uncaught third strike, but he can't run there since first is occupied with less than two outs. If the catcher makes a play on him, and that allows another runner to advance, shame on the catcher.
