I agree 100% with Sergei... The game will give Galarraga more fame than just a "regular" perfect game would... he's getting pub on all kinds of non-sports shows, and every time in the future a pitcher throws a perfecto, the announcers will say "There's the 22nd perfect game... well, 23rd, if you count Galarraga's, which was really a perfect game, but not officially"...
At this point, what else is there to say? All angles have been beaten into the ground. Bad call, tragedy, apology, class, more class, nice story, no reversal... done. Only thing to discuss is how MLB will institute instant replay, and how soon.
