That's Interference!

Nice. . I get that.

But now I realize that I have been calling this wrong.
Ball hit down RF line, F3 OBS BR/R before Fn gets to the ball.
OBS occurs between 1B and 2B and is minor.

(I have been saying "2B" because of the judgement made at the time of the OBS. So, I want to get this clearly as possible.)

Then ball gets away from Fn.
Fn finally gets ball.
Fn throws to cutoff/relay (F4 at edge of grass) who relays to F2 at HP.
Ball gets away from F2, but recovers just in time to tag BR/R.
(bear with me on this - PLEASE)

You see where I am going with this?
PLAY: An attempt by a defensive player to retire an offensive player.

So, all of that would be considered the "Play", and none of that would be considered "Subsequent" action, which is moot anyway, because the only time "Subsequent action" matters is when a play is made on a different runner.

Meaning I don't have to judge what base would have been reached until the play is completely over?

no flames (well maybe I deserve something)
