Miguel Cotto, Canelo Alvarez finalize Nov. 21 bout in Vegas

LAS VEGAS (AP) Miguel Cotto and Saul ”Canelo” Alvarez agreed Thursday to a bout scheduled for Nov. 21 at the Mandalay Bay Events Center.

The fighters’ camps have spent several months negotiating the HBO pay-per-view bout. It’s the latest chapter in the long-running rivalry between boxers from Puerto Rico and Mexico.

They’ll fight for the WBC middleweight title, but at a 155-pound catch weight. That’s 5 pounds lighter than the middleweight limit, since neither fighter is a natural 160-pounder.

Puerto Rico’s Cotto (40-4, 33 KOs) is the WBC middleweight champion after beating Sergio Martinez last year. He has revitalized his long career with three straight victories since teaming up with trainer Freddie Roach.

Mexico’s Alvarez (45-1-1, 32 KOs) has won three straight fights since losing to Floyd Mayweather Jr. in 2013.
