Camila Zamorano will put her CMB atomweight world title on the line on Saturday, August 22, when she faces Perla Pérez in San Luis Potosí. The bout tops the card “México, Tierra de Victorias” at Arena Potosí, with free admission for the live event and a late broadcast on Box Azteca.
The timing makes the defense a search target now: the in-person card begins at 5:00 p.m., while Box Azteca starts at 11:00 p.m. central Mexico time, giving fans two ways to follow a title fight that carries real stakes for Zamorano’s unbeaten run. She arrives with 14 victories, one by knockout, and no defeats, while this will be her third world title defense and her first outside Sonora.
Zamorano has been building toward this moment since June 2025, when she won the interim CMB world title by unanimous decision over Mika Iwakawa. After Tina Rupprecht retired, she was recognized as the undisputed champion, then defended her crown against Sana Hazuki in October 2025 and beat Claudia Verónica Ruiz by unanimous decision on February 21 in Hermosillo. The San Luis Potosí defense now extends that run into a new setting, with the title and the unbeaten record both exposed again.
Pérez, 32, brings more than a decade of professional experience into the ring and a record of 9 victories, 9 losses, one draw and one knockout. She is the CMB Continental atomweight champion, and her style is built around constant pressure, forward movement and exchanges at close range. That kind of opponent can make a clean boxer work harder than the numbers suggest, which is why Zamorano described the bout as a hard fight and “una guerra arriba del ring.”
There is still one detail fans will watch for on fight night: the exact ringwalk time for Zamorano has not been confirmed. What is clear is that the title defense will be staged as part of the activities of Fenapo 2026, and the combination of free entry, national television and a champion leaving Sonora for the first time gives the card a reach beyond the arena itself.
By the time the broadcast starts at 11:00 p.m., the night should already have told its story in the ring. If Zamorano gets through Pérez, she will have defended her place at the top while taking her first world-title test outside her home state; if she does not, the pressure she expected will have turned into the upset boxing always promises.
