"The referee stopped the fight. He's the law of the ring. I could have fought another 10 rounds, but referee stopped the fight," Alvarez said. "It's not my problem."
Angulo was not happy with the stoppage.
"I told Tony he did the wrong job tonight," Angulo said. "The referee tells us to take care of ourselves at all times. I can take care of myself. My plan was to work harder in the final four or three rounds. I had good preparation for this fight."
Said Virgil Hunter, Angulo's trainer: "I'm very upset. I told the referee and the doctor that if Canelo put two or three shots together that I would stop the fight. He landed one punch. Everyone knows Alfredo was coming on strong, everyone knows that."
Alvarez came into the fight under a cloud of come controversy. Knowing he would be unable to make the 154-pound contract weight at Friday's weigh-in, he negotiated the limit up to 155 pounds. He made the weight, paid Angulo $100,000 and agreed to a Saturday weight check at 3 p.m. PT, at which he was not permitted to weight more than 168 pounds.
The weight check was closed but according to a Golden Boy Promotions official, Alvarez, who earned a minimum of $1.15 million, was 166 pounds. Angulo, who made $850,000 (including the additional $100,000) did not have to weigh in again.
By fight night, Alvarez weighed 174 pounds on Showtime's scale and Angulo was 170 -- light heavyweights. But Alvarez looked sharp, fast and powerful as he abused Angulo, even though the crowd was not happy with the stoppage and booed throughout Alvarez's post-fight in-ring interview.
The fight was the first of what is supposed to be three pay-per-view fights for Alvarez this year with the next one targeted for July 26 and another on Nov. 22, although there are no set opponents.
But based on Alvarez's drawing power, it might not matter who he faces.
"That's the medicine the doctor ordered," Golden Boy chief executive Richard Schaefer said. "I think it was a great performance.
"He threw great combinations, he fought a very smart fight and he dominated the fight. It was a beautiful display of talent."
