It was the last out.
The kid got the next one too.
Just say, "The game ended here!
The next at bat, didn't happen".
Everyone in the world knows the Ump blew it.
Jim Joyce will thank you.
Hell, the last thing on this earth that guy needs is to have to live the rest of his life having screwed up a PERFECT GAME.
Let it collect the dust of baseball history as a perfect game, rather than have it stand out, for as long as there is baseball, as the game Armando Galarraga got "Joyced".
Then call the replay rule we'll have next year "The Galarraga Rule".
