To the topic at hand... perceived interference by BR going to 1st (where else can she go - right?).
I think a couple of you, quietly, gave the answer that I would give.
Some of you cast doubts about calling interference in situation D where the ball hits the BR but the umpire thinks that maybe, perhaps, possibly the throw would not have reached F4 in flight. (in time?) Well I'm sorry folks but scenario D is the only one for which I would definitely call interference.
Scenario D is the only one with actual evidence that the BR interfered. All the others are a
guess... I wouldn't say judgement. I would definitely say guess. I'm not there to guess. Catcher, prove to me that the BR interfered or she is safe.
Scenario A - poor throw - bad placement.
Scenario B - again, poor throw.
Scenario C - no throw, poor choice.
Scenario D - flight has nothing to do with it. Scoop it out of the dirt. Ball hit BR. BR was not in a legal location. "Time. Dead ball. BR is out." Other runners return to last base touched at time of interference.
Scenario E - poor throw. How do I know it wasn't going to be too late on the first pump.
I'm thinking that you guys need to eat less pickles.

Just funnin'
