Calculating, measured, calm and supremely confident, showing some improved footwork, Spence Jr. (23-0, 20 KOs) took apart a very good—and very brave—Peterson, whose cornerman, Barry Hunter, wisely stopped the fight at :01 of the eighth round. It was the second time Peterson (35-4-1, 17 KOs) had been stopped in his career, and the victory extended Spence’s knockout streak to 10 straight.
