Brooklyn welterweight Sadam “World Kid” Ali rose from a first-round knockdown and then floored rival Jay Krupp in both the third and final stanzas of Monday night’s eight-rounder at Barclays Center on Golden Boy Live! to win a unanimous decision.

A 25-year-old member of the 2008 Olympic team who was fighting for the first time under the Golden Boy banner, Ali rose to 17-0 with 10 knockouts, while Krupp slipped to 17-6 with eight stoppage wins.

Krupp’s three-fight winning streak was ended by Ali, who was coming off October’s second-round knockout over Ronnie Warrior Jr. at the Aviator Sports Complex in Brooklyn.

In other bouts, junior welterweight Michael “The Artist” Perez unanimously decisioned Miguel Zuniga over 10 rounds, while light heavyweight and 2012 U.S. Olympian Marcus Browne went the distance for the first time, scoring an eight-round unanimous decision over Lamont Williams.

Also in action in four-round unanimous decision victories were junior lightweight Emmanuel Gonzalez over Noel Echevrria, and super middleweight D’Mitrius Ballard over Lekan Byfield.

Junior featherweight Claude Staten Jr. also battled to a four-round majority draw with Derrick Bivins.
