Kirk Gibson's incredible walk off homer in the ‘88 world series against the monstrous A's in game 1
The greatness of Scully's call is that after the dramatic build-up during Gibson's long at bat, once he announces that Gibson went yard, for the next 70 seconds, Scully doesn't utter a sound, letting the sights and sounds of the moment tell the tale.
If it happened today, we'd hear Costas or Buck discussing something about global warming or the BLM movement as Gibson hobbled around the bags.
