I went to a Yankees/Red Sox game on August 30, 1967 and came across the ticket stub in my storage locker.  This was an 11 inning game.  Al Downing pitched all 11 innings for the Yankees. Ken Harrelson, Carl Yastrzemski, George Scott and Rico Petrocelli appeared for the Red Sox and Roy White and Tom Tresh appeared for the Yankees.  There is a little video clip from the game online.  Carl Yastrzemski hit the go ahead home run in the top of the 11th.  The ticket stub is in OK shape, it goes back to time when part of the ticket was torn by the ticket taker.
