I was aware of the rule, I just didn't know that it could take up to 6 days for the ruling to occur. (Angels get 24 hours to submit, MLB takes up to 5 days to rule.)
In this day and age, that really seems excessive. If they could rule on it today, they would have a chance to replay tomorrow if need be.
What keeps teams from protesting any old blown call? You never know what call a game will turn on. Does there have to be demonstrable change in scoring, like there was last night? Konerko would not have been on base when the home run was hit.
