Tim Tszyu has knocked out American Tony Harrison in the ninth round to claim the interim WBO belt and emulate his legendary father Kostya in winning a world boxing title.
Tszyu pummelled Harrison with a series of savage blows to the head and body, forcing the referee to stop the fight at Sydney's Qudos Bank Arena on Sunday.
The hometown favourite's victory came 28 years after Kostya knocked out Jake Rodriguez at the MGM Grand in Las Vegas - when Tim was barely two months old - to capture his maiden world title, the IBF super-lightweight strap.
