LAS VEGAS, Aug 11: Mexico's Omar Nino, fighting past 10 rounds for the first time in his career, dethroned previously unbeaten Brian Viloria on Thursday to claim the World Boxing Council light flyweight title.

The challenger from Guadalajara, in his first fight outside Mexico, took a unanimous decision by judges' scores of 118-110, 117-111 and 117-112 and dedicated the triumph to his son Omar Jr, born just 15 days earlier.

Nino improved to 24-2 with one drawn while Viloria suffered his first loss after a 19-0 start to his pro career. It was the second defence of a title he took from Eric Ortiz last September.

The result dims the chances for a showdown fight against undefeated World Boxing Association champion Koki Kameda of Japan. Viloria said talk about a fight with Kameda was not a distraction to him for facing Nino.
