After reading your posts and re-reading the original, I would like to say this is how I would handle this (ASA and USSSA slowpitch is my normal game): Watch the whole play through, and as soon as the first baseman actually has the ball in his hand, call the runner out. He cannot be called safe since he overran the base. I have UIC's here who'll ream my *** if I called him safe without him touching the bag.
