The ump who fricked up the perfect game
I think it's the best thing to happen to Gallaraga, who would've been completely forgotten had that call not have cost him a perfect game. Instead of being a footnote, his imperfect game will be remembered forever.
Also, Joyce was the height of professionalism and acted precisely how an umpire should act after making a bad call. He admitted his mistake, made no excuses, and immediately went out to face the music. Mistakes happen, but he handled his worst professional moment with a great amount of class. It's why Joyce is such a highly regarded umpire despite now being famous for a bad call.
