I have OBS as the fielder is en route to field the ball, not in the act of fielding it.

By the way, the OBS rule supplement is unhelpful in regard to the red text above, as it omits the thrown ball part of the rule.

I had used the RS recently to revise my INT and OBS understandings and not long after ruled a sitch incorrectly where a fielder was waiting on a thrown ball while on the base path when collided with by a runner.

And yes, I know, the supplement is just a supplement and the rules are where the rules are .
