Interference vs Fair/Foul

If the ball was still a fair ball at the time of the collision, this sounds like interference to me. What the ball does after that is irrelevant.

I agree that if the umpire deems the fielder in the act of fielding then we have interference. Does the reasonableness of fielding the ball every come into consideration? Here's an example. R1 on first base. Slow roller hit up the first base line. F3 moves up into the base path of R1. The ball stops well short of F3 who then has to move up to get to the ball. Do you consider F3 in the act of fielding when she moved up? If so, you have interference when R1 collides with F3. But my contention is that a smart F3 might obstruct the runner but claim she was in the act of fielding. If to field the ball she needed to move further up first base line then I think we have obstruction. In other words, do you protect a fielder who is within the runners base path and they have no reasonable right to be there (i.e no chance of fielding the ball in that position)?
