The BU had his back to 3rd base " watching " the play develop at 1st. I had the runner from 2nd out of the corner of my eye, but when BU came up pointing at me, I lost the runner from 3rd and proceeded to make the call at 1st. You may be right about the no call until all play had ceased. I didn't think of that because I was caught by surprise by the request from BU to make the call.
And I agree that if he had moved to B or even got a better line of sight to the play, he would have been OK. I think he might have just figured it would be an easy call to make and didn't hustle. I am not criticising him because I don't know what went on in his mind. His post game explanation was kind of weak, but after three games in the heat, we were both pretty tired.
Anyway, I am comfortable this will not occur again. My notes-after-game book continues to grow.
