Thanks to my favorite tipster, the actual footage of Tony C's game was stumbled upon. The screengrabs shown have been cropped to protect the actual source.
I can tell you that this footage existed for over 20 years. After that, I have no knowledge if the original source footage is still there. As I said before, MLB appears to have hodge-podged the clip in their special together. That doesn't mean they DON'T have this footage, as in the past they've used poor quality footage or no clips at all to talk about games or events that they actually have broadcast footage for. What I do know is that this clip, which is part of another broadcast, still exists and is out there.
