Williams was a hurricane from the first bell and had knocked Hall down inside the first 45 seconds of the fight.
It was a slaughter right from the start when Williams landed a heavy left hook after just 15 seconds that had Hall falling back onto the ropes.
The 45-year-old never recovered.
Suddenly it was very easy to tell Williams was nine years younger and boasted an 11kg weight advantage.
There was some confusion with the referee appearing to wave the fight off as Hall got back to his feet the second time.
