Obstruction?

While you may argue that the runner should be paying attention to the base coach and not looking to see when the fielder first touches the ball (and frankly, I support that argument), rules exist nonetheless to penalize the fielder with "visual obstruction" in this situation. Sounds to me that MrRabbit may be looking for something similar in ASA.

NCAA softball added such a rule under Fielder Obstruction for the 2012 season (9.4.2.3).

FWIW, as to the initial question raised in the OP, I believe NCAA may be the only organization that currently has a rule in their book covering that specific situation, (9.4.2.7).
Effect for the initial offense however, (unlike 9.4.2.3), is an OBS warning.
