Mullings secured the victory by knocking out the Canadian in the sixth round of the 10-round championship fight to become the first fighter to win the series on two occasions. Mullings first won the series in 2015 when he forced Tsetsi Davis to retire in round seven.
However, on Wednesday night, referee Steve Smoger stopped the fight in the sixth round after Mullings had sent Rose tumbling to the canvas for the second time in seconds. Prior to knockout, Rose was saved by the bell in the fifth round when Mullings caught him with a vicious left, right combination to the head and face.
Mullings won the first prize of $2 million, while Rose took home $500,000. The third place and fourth place boxers were also presented with cash prizes of $250,000 and $200,000 respectively.
Tsetsi Davis who lost to Mullings in the semifinals was presented with the third place check whilst Richard Homles took him the fourth place cheque.
