Keep lining 'em up, and Oscar Collazo keeps knockin 'em out.

The Ring, WBA, and WBO minimumweight champion Collazo continued to turn heads on Saturday night as he scored his fifth stoppage win in six world title fights, this time against Edwin Cano in Cancun, Mexico.

The all-southpaw slugfest came to a brutal end when Collazo (12-0, 9 KOs) capped off his thoroughly dominant performance with a crushing combination to the head of Cano that culminated with a right to the body.

Battered and beaten, Cano (13-3-1, 4 KOs) backpedaled into a corner and took a knee as referee Miguel Canul counted him out at the 1:12 mark of the fifth round.

The Puerto Rican pugilist Collazo, confident and calculated as ever, proved he was levels above the outmatched Cano by clinically submitting yet another masterclass performance.

Everything was seemingly working for the efficiently-operating Collazo as he landed a north and south attack with great accuracy. The small yet monstrous Collazo kept crushing the Mexican Cano at all ranges much to the dismay of the crowd.

A bludgeoning and deflating body attack from Collazo in the third and fourth rounds considerably slowed down Cano. Cano started fighting with his mouth open in the fifth round, a clear signal the fight would end soon as he spit out his mouthpiece after absorbing the final shot to the solar plexus.

All in all, Collazo outlanded Cano 125 to 34 – 39 of those shots were to the body.

"I demonstrated power and physicality," Collazo said in the ring following the win. "[I knew I had him] in the fourth round when I started to go down to the body and hit him with good shots to the head. I did OK. It's my 12th fight. I still have things to learn. I've done a lot in so little. I'll give myself a C-minus. I still have a lot to learn."

Collazo said he wants to return in June for a homecoming fight in Puerto Rico.

“This statement was for all of the people who did know what the lower weight classes can do,” said Collazo. “We make it happen. We want that money. We are coming to stay.”
