Retired Runner Hit with Throw

[Manny A]

So, let me ask you this: If the retired runner goes into second base with a legal slide and takes out the pivot fielder who tries to throw the ball to first from the bag instead of clearing it before the throw, are you going to call INT on that?

After all, the runner is retired, so, as you say, she has no rights. She did "act" by executing a legal slide into the base. And she did affect the pivot fielder from making a play on another runner.
