Mexican boxing champion Canelo Alvarez has retained his Super-Middleweight titles after outclassing Avni Yildirim of Turkey this afternoon.

Alvarez retained his world titles with a technical knockout after Yildirim failed to answer the bell for the fourth round.

He dropped the Turkish challenger with a left right combination to the head midway through the third round.

Yildirim survived the round but absorbed sufficient punishment that forced his trainer Joel Diaz to stop the fight.
