Looks as if we lost some threads, but to continue with the discussion of perfect games:

You are correct, bluezebra. Ernie Shore's game is no longer on the official list except as a footnote, along with perfect games broken up in extra innings, shortened by rain, or thrown by multiple pitchers. I guess they felt that although Shore got 27 outs in 26 batters, the game itself was not perfect.

However, as for the original question, a dropped foul ball scored as an error would STILL not negate the pitcher's perfect game. The scorer wouldn't have to cheat. Can't cite a game as evidence, though. A look through the box scores of the perfect games this century, on the chance that the winning side might have had an error, came up dry.

If you're the starting pitcher, you go the distance (at least 9 innings), and you allow no runners to reach first safely, you get credit for a perfect game. I would guess that you would be credited with a perfect game even in a 0-0 rainout after 9 or more innings.
