Sounds to me like you are trying to play Devil's Advocate which is fine in many cases. This, however, is one of those cases where you have taken the scenario to the edge of the cliff. There is no way that you can prove your point (and many have tried through the years). So far, the only ones that have agreed with your idea are the Fast Pitch Softball people. I doubt that Baseball will ever change, but if it does, you are covered!

GF, you don't know all the people who have answered your question so far, so perhaps you're having trouble gauging their credibility. All I'll say about that issue is: when it's you against the world, you might be right but that's not the way to bet.

Second, I will offer that professional umpires are instructed to watch and see whether the batter "offers at the pitch." They are taught that merely holding the bat still does not constitute offering at a pitch. So in the case under discussion, with the pitch out of the zone, the proper call would be: "Ball," or better yet, "No, he didn't go!"

FED 7.2.1B "In bunting, any movement of the bat toward the ball when the ball is over or near the plate area, is a strike. The mere holding of the bat in the strike zone is not an attempt to bunt."

If B1 is holding the bat (motionless) "in the zone" and the ball passes the plate "out of the zone" then I don't see how the pitch could be anything but a ball.

I hate to extend this topic past the OP, however the website says (bolding mine): "Known as the largest all volunteer sports organization in the United States,"

That seems contradictory.
