The defense was St-Pierre's eighth consecutive overall title defense, and his eleventh consecutive victory, as the man that UFC commentator Mike Goldberg has referred to as "The Ultimate Fighting Machine", keeps moving forward.
As some experts and Diaz fans might have expected, Diaz did give St-Pierre a bit of trouble at times, mostly late in the fight, as St-Pierre faltered just a bit in the championship rounds for the second consecutive outing.
Diaz had no answers for St-Pierre's ground game. But, in typical Nick Diaz fashion, seemed to insinuate in his post-fight interview that someone, perhaps a member of the camera crew that traveled to his training camp to get workout footage, had tipped St-Pierre off as to what his tactics would be on the ground.
Far be it from me, someone who has never been in a fight, to tell a professional fighter what strategy to use, but, Nick? By about the twentieth time that you tried to roll through for a kneebar, even I knew what your plan was.
In an interview with commentator Joe Rogan after the fight, Diaz half-heartedly announced his probable retirement from mixed martial arts.
