Jorge Arce, at 31, scored the upset of the night -- at least by by the betting odds, and it doesn't matter what happens in the main event. Wilfredo Vazquez Jr. was an even bigger betting favorite than Manny Pacquiao, but could not hold off Arce, who closed the show in dramatic fashion.
Arce, who led on the Bad Left Hook card 105-102 going into the 12th round, closed the show in a big way by unloading with great fury on the younger man, forcing Wilfredo Vazquez Jr.'s father, Wilfredo Sr., to throw in the towel.
It was a great fight, with Arce (57-6-3, 44 KO) pouring on pressure and coming off the canvas at the end of the third round on a huge left hook from Vazquez (20-1-1, 17 KO). But though Vazquez landed a lot of hard punches in the fight, he could not deter the battle-hardened Mexican warrior, who looked better than he has in years, and picks up a major recognized title in his third weight class. Will Arce join the parade of Mexican veterans who try to win titles in four weight classes?
As for Vazquez, he was certainly not bad in this fight. He was competitive in the fight, but just outgunned by a guy who does not know how to stop fighting. Vazquez struggled with Arce's pressure, and just didn't have quite enough to hang in any longer.
Official scores at the time of stoppage were 107-102 Arce, and 104-104 on the other two cards.
