Another round in the fierce Mexico-Puerto Rico boxing rivalry will play out at the Mandalay Bay in Las Vegas on November 21 when Guadalajara’s Saul “Canelo” Alvarez takes on WBC middleweight world champion Miguel Cotto

Despite the Tapatio’s clear physical advantages, Cotto feels he has enough experience and boxing smarts to win.  “When you have more than one tool in your bag, the opponent can bring whatever style he wants to bring, and you have something in your bag for it. We’ll do the same for this fight,” he said at the press conference.

The fight will be shown live on HBO Pay Per View.
