Canelo (32-0-1, 26 KOs) entered the fight unbeaten and had quickly become one of boxing’s most closely watched teenage prospects.

Cuello (26-1, 10 KOs) arrived as a respected Argentine contender who had never been stopped and viewed the fight as the biggest opportunity of his career.

The contest represented another step up in opposition for Canelo. It offered another opportunity to prove he belonged among the division’s top young contenders. Cuello, meanwhile, had the chance to score the biggest victory of his career.

From the opening bell, the difference in power was obvious. Late in the first round, Alvarez uncorked a perfectly timed left hook that dropped Cuello heavily to the canvas. The Argentine beat the count and fought back with determination, but he immediately found himself dealing with Alvarez’s heavier hands, accurate counterpunching, and growing confidence.

The punishment continued to build as Canelo found openings with both hands, landing hard to the ribs before bringing his attack back upstairs.

His trademark body punching was already becoming a major weapon, and whenever Cuello tried to stand his ground, Alvarez answered with crisp combinations that repeatedly forced him backward.

Cuello refused to look for a way out. Whenever Cuello tried to apply pressure, Canelo answered with crisp combinations that quickly halted his advances. By the fifth round, the punishment was beginning to accumulate.

Cuello’s face showed the effects of the sustained attack, and Alvarez continued finding openings with right hands upstairs before digging hooks into the body whenever his opponent reached the ropes.

The end came in the sixth round. Alvarez trapped Cuello against the ropes and unleashed another sustained barrage of punches. With Cuello no longer returning meaningful offense and taking repeated clean shots, referee Jose Cobian stepped in at 1:22 of Round 6 to wave off the contest.

The victory improved Alvarez’s record to 33-0-1 and earned him the vacant WBC Silver title, another milestone in a rapid climb through the junior middleweight ranks.

The performance also reinforced what many observers had begun to believe: Alvarez possessed the combination of patience, power and composure needed to compete with the division’s elite despite still being a teenager.

Just over four months later, Alvarez defeated Lovemore N’dou to win the WBC junior middleweight world title, beginning the first championship reign of a career that would eventually see him capture world titles at junior middleweight, middleweight, super middleweight and light heavyweight while becoming one of boxing’s biggest global stars.

The loss for Cuello dropped him to 26-2. He continued boxing professionally and later won regional titles, but the defeat served as a reminder of the gulf between a solid contender and a future pound-for-pound great.

Looking back, Alvarez’s demolition of Cuello was more than another prospect victory. It was one of the performances that signaled Mexican boxing had found its next superstar.
