This fight is a rematch of the 2009 Fight of the Year, where Márquez knocked out Díaz in the 9th round. Build up Juan Díaz was a 3-1 underdog for his rematch against Juan Manuel Márquez, but the Houston fighter employed unimpeachable logic to argue that he would be victorious before the battle. In the rematch, Díaz, 26, intended to fine-tune rather than overhaul his game plan since he dictated the action and manhandled Márquez for much of the first fight before Márquez, 36, identified and exploited the chinks in his armour. Without revealing too much of his strategy, Díaz said his key to victory involved a delicate balance between brain, brawn, offense and defense. Márquez, at 36 ten years older than his opponent, retained his WBO and WBA lightweight titles, and won this rematch by outpunching Díaz 288 to 155 on blows which connected. Márquez broke Díaz' lip to pieces with hard left jabs and hard overhand rights that scored, backing Díaz up during this bout. Márquez had a swollen right eye, but it was not a factor. The fight was a clean one. Díaz, a loser of four of his last six bouts, was studying for his law school entrance exam in preparation for a career change before the Márquez bout. 140 pound champion
