Throughout his historic Saturday night, Canelo Alvarez never balked at pursuing Caleb Plant.
He shrugged off jabs, kept charging through Plant’s quick-handed blows and maintained an intent to launch a continued power-punching display on his far-lesser-experienced foe.
Finally, by the 11th round, Alvarez’s steady infliction of damage achieved its goal as he hit a weary Plant with a two-punch combination that knocked down the Nashville fighter.
With his unprecedented pursuit at hand, Alvarez (57-1-2, 39 KOs) completed his execution with a final three-punch combination, closed by consecutive head shots, that knocked out Plant (21-1).
The victory makes Alvarez the first undisputed super-middleweight champion of the four-belt era, a feat he celebrated by donning a king’s crown and standing on the ropes of his corner with both arms aloft.
A sellout MGM Grand Garden Arena crowd of 16,586 roared its approval.
