In the most anticipated fight this year, Terence Crawford dominated Errol Spence Jr. in a battle between the two current best welterweights in boxing. And it wasn't close, as Crawford knocked down Spence three times en route to a ninth-round TKO win at a packed T-Mobile Arena in Las Vegas.
Crawford (40-0, 31 KOs) became the first men's undisputed welterweight champion in the four-belt era. He's the only men's fighter in boxing to be undisputed (four belts) in two different divisions. Crawford won all the titles at junior welterweight in 2017 before moving up to welterweight. Claressa Shields is a two-division undisputed champion in women's boxing having captured all four belts at junior middleweight and middleweight.
Crawford's victory was so dominant that Spence (28-1, 22 KOs), the former No. 4 pound-for-pound, falls out of the top 10.
But Crawford wasn't the only top fighter to shine this past week. Naoya Inoue, No. 2 P4P, produced and impressive as dominant performance against Stephen Fulton to win two junior featherweight world titles. Inoue (25-0, 22 KOs), is a former undisputed bantamweight champion who moved up in weight looking for bigger and better challenges. His performance on July 25 in Japan was good enough to make a claim for the No. 1 spot, but then Crawford had a fight to remember.
"After broadcasting Tuesday's Naoya Inoue masterpiece TKO win against Stephen Fulton, I, as well as many in the boxing media, publicly stated it would take a truly definitive result by Crawford, and that he needed an all-time phenomenal performance that would be forever remembered in order to jump 'The Monster' at No. 1 in my list," ESPN boxing commentator Joe Tessitore said. "Well, Terence Crawford did just that. His demolition of Errol Spence Jr. was more impressive in stamping his place than Mike Tyson's 90-second dismissal of Michael Spinks in 1988.
"Crawford put forth the finest start-to-finish display of skill and savagery at the highest level I can recall over the course of the past few generations. Inoue and Crawford are clearly the two best fighters in the world, by a wide margin. They are passing the eye test, they are acquiring historical records, and they are doing it against world-class competition while cleaning up entire divisions. Inoue is an all-time great, but Bud Crawford is different in ways that are easy to describe and hard to deny. He is my new No. 1 with a slight edge over Inoue, a fighter so exceptional that I'm ashamed to even place a No. 2 next to his name. But TBC may just be the real TBE."
