Yet another INT/OBS question

[CecilOne]

We have to start by separating "base would have reached" from "never out between the bases where OBS".
When it is a "never out" situation, and all previous bases are occupied, then the next base is the only possibility. Hence: "
And a hypothetical scenario (pretty much unrelated to the original question) -- if F1 had successfully picked up the grounder, then R1 and F6 collided, and F1 threw to F5 for an apparent force out, would you agree that I would be justified in awarding R1 third base? I've called obstruction a handful of times but usually when runners are advancing on base hits; I've never had to deal with it on a play in the infield.

It is OBS and you must place the runner someplace. Seems to me that 3B is the only open base. "
