Rule Myth, please help.

[SAWolf]

Hi,

In my country we only have amateur baseball and many of the rules that I learned through playing have been rubbish. I've learned that coaches invent or twist rules to make them suit their particular situation. Now I've been umpiring for a couple of years and straightened out most the stuff like: The hands are part of the bat, the batting box belongs to the batter etc.

But here is another I'm trying to sort out.

I've been told numerous times that a runner must stop to avoid a batted ball. He can't jump over the ball or run passed in front of a fielder fielding a batted ball. If he doesn't stop and the fielder makes an error on the batted ball the runner could be out for interference. If the defense however does make an out the interference falls away. So it is a delayed dead ball situation like a balk.

I think this is possibly a myth heading towards legend because I saw this play and nothing was called: Baseball Video Highlights & Clips | SEA@LAD: Beltre's base knock puts the M's up by two - Video | MLB.com: Multimedia

I can't seem to find this in the actual rules. I've read through rule 7 twice. Could anyone direct me to the Rule No or give me rule references that this could possibly be inferred from or SQUASH the myth?

Thanks
