Camila Zamorano Outpoints Brenda Balderas to Keep the WBC Atomweight Title

Camila Zamorano kept the WBC women's atomweight title on Thursday night in Acapulco, beating Brenda Balderas by unanimous decision after ten rounds. The judges scored it 100-90, 98-92 and 98-92, and the 18-year-old from Hermosillo moved to 16-0 with the fourth defense of her belt.

A Clear Win on the Cards

The fight closed the boxing night attached to the WBC's 64th annual convention, held at Arena GNP Seguros in Acapulco, Guerrero. Zamorano went in as the clear favorite and the scores reflected that, although the reports from ringside agree she did not look her sharpest. No knockdowns were recorded.

The figures are consistent across the Mexican outlets that covered the fight. All three cards went to Zamorano, with one judge giving Balderas nothing and the other two handing her two rounds each. None of the reports named the judges.

How the Rounds Played Out

Zamorano had the height and reach, and she used both from the opening bell. Her jab set the range in the first three rounds, and she mixed in shots to the body when Balderas tried to walk her down. By the fourth she was winning on volume, and live coverage noted that Balderas was already showing signs of fatigue.

The middle of the fight was closer. Balderas, a pressure fighter, kept coming forward and leaned on clinches to smother the champion's work. In the sixth she tied up Zamorano's left arm and came close to taking the round before Zamorano finished it with right hands. The seventh may have gone to the challenger, with Zamorano looking tired and struggling to keep distance.

Zamorano found her way back in the eighth. Her left hook troubled Balderas more than once, and she landed a hard left to the body late in the round. In the ninth she went back to moving and throwing combinations, and in the tenth she caught Balderas with an uppercut near the bell. Balderas took it without going down, and Zamorano raised her hand as the fight ended.

Records and the Road Here

Zamorano won the interim WBC title in June 2025 with a decision over Mika Iwakawa in Hermosillo and was elevated to full champion that October after Tina Rupprecht retired. She has since beaten Sana Hazuki, Claudia Veronica Ruiz and Perla Perez, all on points, and she also came back this year from an appendectomy in April. Her record now stands at 16-0 with one knockout.

Balderas, from Mexico City and nicknamed "La Hormiga", came in at 9-9-2 with four stoppages. Sources disagree slightly on her updated record, which NotiFight gives as 9-10-2 and Tribuna as 9-10-1.

What Comes Next

Zamorano has struggled to make the 102-pound limit, and NotiFight reported that this was her final defense at atomweight. No move to a specific division has been announced. Tribuna pointed to Esneidy Rodriguez, unbeaten at 14-0, as a possible next opponent after Rodriguez won a unanimous decision over Lucia Gutierrez on the same card, but that is a projection rather than a signed fight.

Elsewhere on the card, Luis Nery stopped Francisco Rodriguez early. Reports differ on the exact finish, with one saying the referee waved it off after the second round and another that Rodriguez stayed on his stool before the third. Jonathan Fierro needed only seconds to knock out Sergio Sosa in a super featherweight bout.
