Some fights, like some fighters, just won’t quit. History speeds them by like a freight train at night, it’s one day headlines, the next day breadlines, but tape is our time machine and deliverance. The first meeting on May 7, 2005, at Mandalay Bay Resort & Casino in Las Vegas, Nevada, between Diego Corrales (39-2 at the time), the WBC lightweight champion originally from Sacramento, California, and WBO lightweight champion Jose Luis Castillo (52-6-1), from Empalme, Sonora, Mexico, is a fight for the ages. All fights are not equal, even on paper, but some fights are more equal than others. It can be the result of bold matchmaking. And sometimes the fighters fight their hearts out. Novice or old school, everyone knows when it works and doesn’t. Corrales-Castillo 1 works on a level few fights manage. Nonstop action and rugged noncompliance with basic survival instincts, the fight was boxing at its most primordial, the very essence of a sport still full of surprises.
