I can't think of a code in which the OP would not be a foul ball. (Just to be sure, I'm checking with the YSISF commissioner for their interpretation.)

However, ASA does go its own way on certain plays in the same vein. For example, a fielder can throw his glove at and hit a ball that is a few inches on the foul side of the line and apparently going to roll fair, and it's simply a foul ball. Similarly, a runner can deliberately kick such a roller and render it foul. Other codes (black-and-white rule in NCAA softball, interpretation in OBR) have violations on those plays.

But I don't think that ASA takes the "future" into account—whether the ball had a chance to become fair or actually becomes fair. In any case, the roller in the OP did not have such a chance.
