The fourth meeting between these two fighters generated a significant amount of hype, and the bout still somehow managed to exceed expectations.
It was clear from the start that Pacquiao was active, in shape and ready to fight. It only took until the second round for the announcers to start gushing over Pac-Man's legendary straight left hand.
But it was Marquez who landed the first blow, knocking down Pacquiao in the third round with a hard right hand. Nevertheless, the Filipino fighter was able to get up and regain control of the fight.
In the fifth round, he evened the score by catching Marquez with a straight left hand and knocking down the Mexican fighter.
With an advantage on the scorecard, Pacquiao just needed to avoid Marquez' lethal counter punches. But in the sixth round, Marquez found an opening when Pacquiao attacked and landed a vicious punch directly to Pac-Man's face.
The Filipino star dropped straight to the canvas, and the fight ended as a victory for Marquez via knockout. This is Marquez' first victory over Pacquiao and the first time any of their matchups ended early.
It was a shocking result and after an incredible bout, fans certainly wouldn't mind seeing a fifth fight.
