Errol Spence Jr. fulfilled a sanctioning organization’s obligation Saturday night.

Nothing more, nothing less. That’s Spence’s perspective on his quick knockout of overmatched mandatory challenger Carlos Ocampo.

When the heavily favored Spence was asked afterward if he sent “shockwaves” through the welterweight division by knocking out Ocampo in the first round, the unbeaten IBF welterweight champion downplayed his easy victory. The powerful southpaw views his win Saturday night just like he assessed Terence Crawford’s ninth-round stoppage of Jeff Horn in their WBO welterweight title fight a week earlier.

“To be completely honest, man, this is something I was supposed to do,” Spence said during the post-fight press conference. “I’m gonna be a hundred-percent honest. I love being 100 with the fans and I love being 100 with the people. It was something I was supposed to do. I mean, I’m a pound-for-pound fighter and, you know, I fought him because this guy was my mandatory and the IBF called me to fight this guy.

“So I did what I was supposed to do. I got him out of there, looked impressive and, you know, we really don’t take anything from this victory. We’re gonna stay focused, gonna take probably two weeks off and then we’re gonna get back in the gym and practice on things and sharpen up our tools.”

Ocampo, completely unknown and untested, was such a huge underdog against Spence that Las Vegas sports books weren’t even taking bets on their scheduled 12-round, 147-pound title fight in Frisco, Texas. Multiple Internet sports books posted Spence (24-0, 21 KOs) as a 100-1 favorite over the 22-year-old Ocampo (22-1, 13 KOs).

Spence punished Ocampo with a left-right combination to the body that sent Ocampo to the canvas with three seconds to go in the first round. Ocampo couldn’t get up before referee Laurence Cole counted to 10 and their fight was stopped with no time remaining in the first round.

Despite Ocampo’s low profile, the 28-year-old Spence’s first title fight in his home area drew a crowd of 12,604 to Ford Center at The Star, the Dallas Cowboys’ training facility.
