Being ejected can only be for the duration of the game, so my question would be, when is the game officially over? I know there used to be some quirky rule about a walkoff HR not counting if the batter wasn't the winning run (as soon as it crossed, the game was over, all other runners stayed in their place). So things can be a little weird. Is it over as soon as the HR goes over the fence? Or is it not over till the batter steps on Home. I'm pretty sure its the last... in which case if Kinsler was on the field before that, he was breaking the rule. If he has just waited till foot met plate, in my opinion, it would be a different situation. I would be upset about an ejected player not being allowed on the field after the game.
