Deflected ball and interference

[greymule]

I've had this play many times, typically when the ball goes off the pitcher and the runner from 2B runs into F6 trying to field it. It's usually a no call. I interpret "intentional(ly)" as "couldn't be expected to avoid." If I thought that the interference could reasonably have been avoided--that an alert runner would not have interfered--then I would call it. But I haven't seen that one yet.

Is there any difference between "make a play" and "make an out"?
