How would you rule on these plays.

OK. Even though I believe I'm in over my head in this discussion, let me try an observation.

R1 advances toward second and *sees that he has been forced out at second. His 'play' is now over. If he chooses to remain in a position that alters the throw from second baseman to first, or if he is actually struck by the thrown ball from second, I would likely judge that action to be intentionally interferring with a thrown ball: Interference/DP.

Get down, get out of the way, your play is over. You have no right to be in the play. You're out.

This assumes a slow evolving play. My resistance to calling interference was based on the play in which the fielder tags the base and make a throw to first nearly simultaneously, giving the runner no time to evade. This is the DP I see most often.
