MONTREAL, Oct 20: Unbeaten Lucian Bute stopped Alejandro Berrio in the 11th round here on Friday to seize the IBF super middleweight title.

Bute, who opened his pro career with 15 consecutive knockouts, improved to 21-0 with 17 victories inside the distance.

Berrio, 31, was making his first defence of the title he won in March when he knocked out Robert Stieglitz, a boxer who had beaten him in 2005. Berrio fell to 26-6. Bute had become the mandatory challenger for Berrio’s belt with a 12-round decision over Australian Sakio Bika on June 15.—AFP
