Interference

[Matthew F]

That's a good one Dave. I'm still scratching my head...

Since F1 is fielding the ball (and it was a swinging bunt), I'm assuming this stitch didn't occur in the general vicinity of home plate, which "no call" is generally made if contact occurs.

If F1 was in the act of fielding the ball (per your stitch), he should be protected and interference would be called. What I don't know for sure, is if the fact it's also a foul ball would have an impact on the ruling? I guess I would get an earful when I called the ball dead on the interference and then the runner out.
