Diz pitched a no-hitter, one Saturday, in the first game of a double-header. In the second game, his brother, Daffy, also pitched a no-hitter. Dizzy was furious, and insisted the manager allow him to pitch the afternoon game the next day. You got it -- ANOTHER no-hitter. What a man, and what a tremendous legend he was.
His brother did, yes. Not Dizzy.
