Chances are that you'll never see a pitcher's duel like the one Juan Marichal and Warren Spahn staged in San Francisco back on July 2, 1963.
They kept battling for 16 innings before Willie Mays hit a one-out home run off Spahn to give the Giants a 1-0 win over the Milwaukee Braves.
Sixteen innings and not a single pitch came out of the bullpen.
