Camila Zamorano Retains WBC Atomweight Title in San Luis Potosí

In a small division but on a big stage for her career, Camila Zamorano once again looked every inch a world champion.

The 21-year-old Mexican, already the youngest reigning world titlist in the sport, boxed to a composed unanimous decision over the rugged Perla Pérez on a Zanfer Promotions show at Arena Potosí in San Luis Potosí, México, on August 22. The judges’ cards – 98-92, 98-92 and 97-93 – told the story of a fight she controlled, if not dominated, from range.

This was Zamorano’s third defence of her WBC atomweight world title, a belt she first held in interim form before being elevated to full champion. The status has not weighed her down. It has sharpened her.

Jab, feet, and a champion’s composure

From the opening bell, Zamorano (15-0, 1 KO) went straight to the tools that separate prospects from champions: a disciplined jab and smart feet.

Working off the back foot, she snapped out her lead hand and refused to be drawn into the kind of close-quarters exchanges Pérez wanted. The reach advantage was obvious. So was the intent. Zamorano kept the fight at her preferred distance, spearing Pérez with straight shots and sliding away before the challenger could set her feet.

Pérez (9-10-1, 1 KO) answered in the only way she could. She marched forward, round after round, trying to turn the contest into a fight rather than a boxing lesson. Whenever she felt herself edge into range, she let her hands go in clusters, hoping volume could disrupt Zamorano’s rhythm and sway the judges.

There were moments when that pressure paid off. Pérez’s aggression occasionally forced the champion to the ropes, and the underdog nicked pockets of success when she could crowd Zamorano and make the younger fighter trade.

But those moments never lasted long.

Pressure meets polish

Each time Pérez seemed to close the gap, Zamorano reset the terms of engagement. A double jab here. A neat pivot there. A quick step back, followed by a clean right hand. The champion’s style was not reckless or spectacular; it was measured, tidy, and quietly dominant.

The pattern became familiar. Pérez on the front foot, swinging when she sensed an opening. Zamorano circling, touching her with the jab, picking spots for straight punches and quick counters. The challenger’s effort and heart were never in doubt, yet the champion’s control of distance and tempo kept the fight tilted her way.

By the late rounds, the gap on the scorecards felt inevitable. Pérez still surged forward, still tried to drag Zamorano into a brawl, but the champion refused to abandon what had worked all night. She boxed, she moved, she banked rounds.

When the final bell rang, there was little suspense. The unanimous verdict simply confirmed what had unfolded across ten rounds: a young champion doing exactly what a young champion is supposed to do.

A quiet force at the lightest weights

Atomweight rarely grabs headlines in a sport obsessed with heavy hands and heavier divisions, yet Zamorano is quietly putting together the kind of résumé that demands attention. Still unbeaten. Still improving. Still the youngest world champion in boxing.

The bout, broadcast live on Azteca 7 in México and now available in full on YouTube, won’t go down as a classic war. It will, however, sit as another clear marker of Zamorano’s poise and maturity under the lights.

She entered Arena Potosí as the WBC atomweight champion. She left with the same belt, a wider gap between herself and a seasoned challenger, and another defence on the record.

The question now is simple: who dares to test her next?
