After win, Álvarez in class of his own

With a destructive barrage of power punches in the waning minutes of a difficult fight, Canelo Álvarez added another achievement to his overflowing list of boxing accomplishments. The 31-yearold Mexican pound-for-pound superstar is the undisputed super middleweight champion of the world. Álvarez became the first four-belt world champion at 168 pounds in boxing history Saturday night, stopping Caleb Plant in the 11th with two dramatic knockdowns. Álvarez (57-1-2, 39 KOs) added Plant’s IBF title to his own WBC, WBA and WBO belts with a tactical performance culminating in a display of his vaunted power to finish the previously unbeaten Plant (21-1) at the MGM Grand Garden Arena in Las Vegas. “It was truly a historic night, and I’m so proud to be a part of it,” said Álvarez, who’s generally recognized as the top fighter in the world regardless of weight class. After winning four fights in a grueling 11-month span, Álvarez is the sixth man to be a four-belt champion. He joined junior welterweight Josh Taylor as the only current undisputed champs of their weight class.
