Quebec City - Canada's Adonis Stevenson easily retained his World Boxing Council light heavyweight title Friday, knocking out challenger Dmitry Sukhotsky in the fifth round at the Colisee arena.
The 37-year-old southpaw Stevenson (25-1, 21 KOs) dropped Sukhotsky with a straight left hand on the chin near the end of the round.
"I know with my power I don't need to force it," Stevenson said.
"The knockout will come. I waited and bang, I caught him."
It was one of three knockdowns by Stevenson in the fifth round of the lop-sided fight.
The first knockdown was a devastating left hand to the head. The second was an overhand right that glanced off the left side of Sukhotsky's face.
Sukhotsky was knocked down four times in total in the fight that was scheduled for 12 rounds.
It was the fourth title defense for Stevenson since he grabbed the belt with a first-round knockout of Chad Dawson in June 2013.
Stevenson has won 12 fights in a row, including four times in 2013.
The 33-year-old Russian Sukhotsky (22-3) had a four-bout winning streak ended.
Stevenson is expected to next face the winner of a March fight between Sergey Kovalev and Jean Pascal.
Asked about a possible fight with Kovalev, Stevenson said: "You have to come to me."
