Canelo Alvarez is a substantial favorite over Edgar Berlanga in title fight

LAS VEGAS (AP) — Edgar Berlanga has yet to taste defeat after 22 professional fights — 17 by knockout — and he not only said he's intent on keeping his undefeated record intact, but to win in six rounds Saturday night.

But if forced to go the distance, Berlanga allowed that would be fine as well.

Canelo Alvarez isn't buying any of it.

“It’s easy to say you’ll knock me out, but it’s much more difficult to do it," Alvarez said. “Saturday night is going to be very difficult for him for sure. I’ve prepared for the knockout. I love the feeling of a knockout and I’m going to do my best to get it done.”
