Select any wrestler and any kind of match. After the match has started, go to your opponent and press Up + Triangle to get in a test of strength. Then, press Triangle, Square, X, and Circle rapidly and repeatedly. Keep doing this until your opponent's meter is in red, then execute any move of your choice. Note: This may not always pin on the first time.
When the match starts, go outside of the ring and get a weapon. Hit your opponent with it about four times and he will begin flashing red. Do a finishing move on him and you will win.
