Batter/Runer Interference

[Andy]

A fellow blue and I had a discussion on a play in his game on Saturday. Rec league, 14u, ASA rules.

The play: Less than two outs, 1st base unoccupied, catcher fails to catch strike three. BR takes off for first, catcher throws over F3's head and into right field. My buddy, who is working alone, calls the BR out for interference. His explanation is that she was running inside the foul line and affected the catchers throw to first base.

I believe that this was an incorrect interpretation of 8-2-E. The rule states that the BR cannot interfere with the fielder taking the throw. The rule does not mention the fielder making the throw. I contend that because F3 could not have caught the ball, no interference should be called. Had the throw hit the BR or had she blocked the view of F3 on a throw F3 had a chance to catch, then the interference call is appropriate.

What do you all think?
