Interference while Standing on 3B

[bwbuddy]

I agree with all of you, but I was looking for a rule book where I am right now, and the only one I could find was ASA (I work with a lot of females) - now I'm confused. Here's what it says:

Rule 8, Section 7: "The batter is out when:" J. "When the runner interferes:

1. With the fielder attempting to field a batted fair ball or a foul fly ball, or
2. With a fielder attempting to throw the ball, or
3. Intentionally with a thrown ball.

EFFECT: The ball is dead and the runner is out. All other runners must return to the last base touched at the time of the interference.

EXCEPTION: If the interference prevents the fielder from catching a routine fly ball (fair or foul) with ordinary effort, the batter is also out.

I may be doing some ASA umping this summer, and I'll post this on the softball board, but would like your comments.
