Interference on a DP

[mbyron]

I would call it this way:

If the INT occurs clearly AFTER R1 was safe (e.g., pop-up slide): then there's no DP, "Time, that's interference." R1 out on the INT, BR awarded 1B (it's an award because the ball is dead).

If the INT occurs AS R1 reaches 2B or BEFORE (hands up, collision, etc.): then the INT is an attempt to break up the DP, "Time, that's interference" R1 and BR out.

We usually see the latter scenario.
