It took Josh Wale just seven minutes to overcome the challenge of Iddi Kayumba on Friday night at the Metrodome.
Brampton's Wale, 31, was dominant against the southpaw from Tanzania.
After weighing up the opponent in the first round, Wale decked him in the second with a body shot just moments after landing a big right hand.
It was all over with a minute gone in the third with Kayumba down in agony from a left hook to the body.
Wale will return to action at the same venue in June with promoter Dennis Hobson hopeful of securing a world title shot for him in 2020.
