The Braves actually scored three runs in the bottom of the 13th when Adcock homered with two men on base (including Aaron who was intentionally walked). Aaron pulled a bonehead play by allowing Adcock to pass him on the basepaths and the homerun was disallowed and counted only as a double and officially only one run scored.
True. The SI piece explains why Aaron did what he did. The leadoff hitter in the botttom of the 13th reached on a throwing error;Matthews sacrificed him to second; and Aaron was intentionally walked, setting the stage for Adcock's homer, which Aaron mistook for a ground rule double. He therefore left the basepath after touching second even though Adcock rounded the bases. While newspapers erroneously called the score 2-0 because of Aaron never touched home, the score was 1-0 and Adcock was credited with a double and an out at second base.
Here is the box score and play by play summary of that historic game:
