The worst call in MLB history?

Quite possibly. Hell, just look at what the umpire had to say about it:

"It was the biggest call of my career," an emotional Joyce told reporters, "and I kicked it. I just cost that kid a perfect game."

That would have been the first time in history that there had been three perfect games in one season, by the way.

Allahpundit thinks that this will result in instant replay being instituted in the near future. I don't think that would be good for the game, but I think he's probably correct that it's gonna happen.

Update: As Drew M. (no relation) points out at the Moron Mothership, both the pitcher and the ump displayed a great deal of class after the game.
