"Played Every Inning of Doubleheader 5-3-64"

I sent a request to Ed Kranepool asking him to tell the story on a baseball about his memory of playing every inning of the longest doubleheader games by time and this is what I received:

"Played 50 innings within 24 hr period.  Wish the game went longer so it started in May and would have ended in June."
