Unbeaten American Errol Spence Jr has retained his IBF welterweight title after knocking out Mexican challenger Carlos Ocampo in the first round.
Southpaw Spence Jr improved to 24-0-21KO as Ocampo lost his own unbeaten record on his first venture outside Mexico.
Spence Jr hit Ocampo with a right hand to the body that sent the challenger to the canvas in front of a sold-out crowd of 12,000 at the Ford Center facility in Texas.
Spence Jr has not been taken the distance in four years, and his 11 stoppages in a row include last year’s knockout of Kell Brook in England and January’s stoppage of compatriot Lamont Peterson.
Spence Jr now hopes to fight the winner of the vacant WBC welterweight championship decider in August between Americans Danny Garcia and Shawn Porter.
Reflecting on his quickfire defeat of Ocampo, Spence Jr said: “I was a little disappointed, I wanted to give the crowd their money’s worth.
“I wanted him to sustain a bit and give him some punishment, but the body shot got him and I dropped him.
“It was a great victory. It was really short, so it is hard to describe. I took my time, I tried to use my jab. He was a little bit awkward, but I caught him and was able to actually hurt him.
“I don’t get paid for overtime. If I can get him out in the first, great, but I wanted to carry it, go to the fourth or fifth round for the fans.”
Ocampo said: “I got overconfident at the end of the round and he caught me.”
