Not that it makes it better, but Joyce has already made a comment and acknowledged his monumental fuck-up.
He could have been a dick about it like some umps would (Joe West would have his publicist issue a statement the next day that was vague and never accepted any blame), but he manned up the minute he saw the replay.
"I just cost that kid a perfect game. I thought he beat the throw. I was convinced he beat the throw, until I saw the replay."
"I don't blame them a bit or anything that was said. I would've said it myself if I had been Galarraga. I would've been the first person in my face, and he never said a word to me."
