LAS VEGAS - Terence Crawford stunned Mexican superstar Saul "Canelo" Alvarez to claim the undisputed super middleweight world boxing crown on Saturday, becoming the first man to win undisputed titles in three weight divisions.
In a fight of razor-thin margins, Crawford poured it on in the closing rounds to earn a unanimous decision victory, improving his unblemished record to 42-0 with 31 knockouts.
Crawford had jumped up two weight categories to vie for history, having already counted undisputed titles at super lightweight and welterweight among his titles in four -- now five -- weight classes.
He silenced critics who claimed his sparkling resume was packed with substandard opponents and quieted a raucously pro-Alvarez crowd of 70,482 at Allegiant Stadium, home of the NFL's Las Vegas Raiders.
"For sure this is definitely a signature win," Crawford said. "Moving up two weight classes, being the B-side, fighting a guy that's been undefeated in the division, undisputed.
"My other undisputed runs I had titles, I was coming in as a champion as well. But this one I was coming in as an underdog, no championship belts and I felt like everything was on the line."
One judge scored it 116-112 for Crawford and the other two saw it 115-113 for the American, who had nothing but praise for his opponent.
"Canelo is a great champion," Crawford said. "And he fought like a champion today."
But Crawford added: "I think I was the better man today. I was stronger, I punched harder.
"It means a lot to me," Crawford said. "You know anybody can be a nobody, and that's all they say I've been fighting is nobodies.
"So what can they say now?"
