In what many thought would be a highly competitive match up turned out to be a one sided affair with UFC world welterweight champion Georges St. Pierre easily doing what many have failed to do by stopping lightweight champion BJ Penn in four rounds. Round one started with the bigger St. Pierre holding Penn against the cage while landing short punches. Round two saw St. Pierre takeover the fight completely as he landed heavy strikes from the top position. The beating from the much larger and much stronger St. Pierre continued until the corner of Penn decided they had seen enough. The fight was waved off before the start of round five giving Georges St. Pierre the TKO victory.
