Obstruction or interference

[SanDiegoSteve]

I could be wrong, but I'm going out on that proverbial limb to say "B" is correct.

My reasoning is simple: The runner started out at second base. He was advancing on a hit. He was obstructed.

There. I am going to award this guy home, because F5 has deprived him of his right to run unimpeded. We'll never know whether or not he would or wouldn't have scored had there been no obstruction. I will make the case that he would have, in my judgment. I have the runner protected to home plate. If they subsequently make a play at home on this runner, I have obstruction and the run scores.

Had there not been obstruction, then I would have coaches interference, and that runner would be out.
