Leotis Martin v Sonny Liston.

Not only did Martin upset the odds, he was the only man to truly spark out Liston with a beautiful short Right which knocked the stuffing out of Sonny, followed by a Left/Right finishing 2 punch combo to take Liston out clean.

It's a real shame for Leotis that he couldn't fight again after this, although in all honesty, peak Frazier would have chewed him up.
