Dmitry Bivol has officially entered the pound-for-pound conversation. Bivol scored a big upset on Saturday in Las Vegas, defeating former No. 1 pound-for-pound fighter Canelo Alvarez. He retained his WBA "super" light heavyweight world title and also earned a spot in ESPN's top-10 list for the first time in his career.
Alvarez (57-2-2, 39 KOs), the undisputed super middleweight champion who moved up in weight to challenge Bivol at 175 pounds, falls from the No. 1 spot all the way to No. 4. Despite the close and questionable scorecards, Alvarez was dominated by Bivol, failing to implement any of his typical offense. Bivol's powerful left jab and right hand were used to perfection to hurt Alvarez.
"There is a clear-cut blueprint on how to beat Canelo now," two-division champion and current ESPN boxing analyst Timothy Bradley Jr. said. "Although he did take a risk by moving up, moral victories at this level don't exist. You win, you're a hero. You lose, your stock drops."
Bradley dropped Alvarez from No. 1 to No. 3 on his list.
ESPN boxing writer Mike Coppinger, who dropped Alvarez from No. 1 all the way to the No. 5 spot on his list, said moving Alvarez down was a tough call.
"On one hand, Alvarez shouldn't be punished for daring to be great and choosing to challenge an elite fighter at a heavier weight," Coppinger said. "There's an argument he should drop to No. 2 behind Crawford.
"On the other hand, Bivol shouldn't rise too high on the list after one great victory, but it's difficult to place the Russian behind Alvarez after he so comprehensively defeated him. There's not much separation between the top seven or eight names on this list. Hopefully, someone will make a statement in the ring and pull away from the pack soon."
Another fighter making his debut in the top 10 is unified junior lightweight champion Shakur Stevenson. His impressive victory over Oscar Valdez on April 30 got him enough votes to take over the No. 9 spot.
"Stevenson is in a class of his own," said Bradley, who voted Stevenson at No. 8. "Not only did he beat a great champion, but he completely outclassed a dominant force in Valdez. Michael Jordan made everything look easy, and Stevenson does the most demanding sport in the world and makes it seem peaceful. That is a sign of greatness!"
