HOW LAST NIGHT’S WRESTLING BOUT ENDED. The back loop slam is one of the most spectacular and most effective methods employed by wrestlers to bring a man to the mat. The back loop slam is a favourite method with Champion George Walker, and so quickly are the various movements executed, that even experienced matmen fall into the trap that is set just prior to bringing off the slam. The three stages of the back loop slam are demonstrated above:—(1) Jack Clark imprisons his opponent’s arms with his elbows. (2) Clark swings upwards, sending his opponent right over. (3) Retaining the hold on the arms, Clark falls backwards on to his opponent's chest, pinning the shoulders to the mat. In the majority of cases the victim of the slam is incapacitated, though the effects quickly wear off.
