WBA Super Bantamweight World Champion Nonito "The Filipino Flash" Donaire Jr retained his title and secured his place in the final of the WBSS final Bantamweights series in the co-main-event from the Cajundome in Lafayette, Louisiana.
American Stephon Young from Saint Louis, Missouri was drafted in as a replacement for injured WBO champion Zolani Tete of South Africa who was forced to pull out of the fight on Wednesday with a shoulder injury.
The 30-year-old Young came into the bout with 1 loss and 3 draws in a 23 fight career that saw him challenge unsuccessfully for the Interim WBA title against another Filipino, Reymart Gaballo 13 months ago.
Young started the fight positively with plenty of lateral movement while Donaire cut the ring down on his less experienced opponent. In the 2nd round, Young landed some good straight left hands from his southpaw stance but couldn't slow the constant advance of the Filipino.
Donaire was noticeably the bigger man and carried the heavier firepower which left Young fighting too defensively to win any rounds.
The end came at 2:37 seconds of the 6th round when Donaire countered a left from Young with a right hand to the body and followed it with a perfectly timed left hook to the jaw that flattened Young who had no chance of beating the count.
The 36-year-old Donaire now awaits the result of the May 18th semi-final between Japan's Naoya Inoue and Emmanuel Rodriguez of Puerto Rico taking place in Glasgow, Scotland.
