They sure did. In 1971, when the A’s were in their ascendency, I attended a game that July against the California Angels. Vida Blue was on the mound and Rudy May started for the Angels. Blue went 11 innings and struck out 18, while May went 10 and fanned 11. The A’s finally won in the bottom of the 20th inning when Angel Mangual doubled in Curt Blefary. It was truly a classic.
20 innings. Wow! Were you the only person still in the stadium when the game ended?
