question on "interference"

[MD Longhorn]

I see your point, and could probably support it against most coaches should my partner make such a ruling.

But I don't see how the ODB's actions as described in the OP can be construed as "no deliberate interference by the on-deck batter". Sure it was deliberate. I see no difference between remaining intentionally in the path of a slow rolling ball and moving INTO the path of a slow rolling ball.
