Amanda Serrano has announced that she wants to add one final historic milestone to her already legendary boxing résumé before she steps away from the sport she has dominated for years. The current unified featherweight champion will travel to California on August 21 to face Argentina's Lucrecia Manzur in what is being billed as her 50th professional win and a potential record‑breaking knockout. Serrano, who already holds the joint‑record for most knockouts in women's boxing with 32, says that stopping Manzur before the final bell would give her the 33rd stoppage that would put her alone at the top of the all‑time list. "This is definitely my last goal," the seven‑division world champion told Sky Sports, explaining that the prospect of eclipsing Christy Martin's knockout tally is the only thing left for her to chase.
"Those little goals are what get me out of bed in the morning. This one – the 50th win, the 33rd KO – is my final farewell, and I feel I've already achieved everything I set out to do when I first laced up gloves." The upcoming bout has taken on added significance because it will be streamed on TikTok, giving Serrano a massive platform for a potential viral moment. She emphasized that the fight is "special" not just for the personal records at stake but also for the exposure it will receive on a social‑media‑driven audience. "I guarantee the 50th win is coming, and we're working on the 33rd knockout," she said.
"Manzur is a very tough fighter, a fellow Latina, and she'll come forward with everything she has. The new generation of women’s boxers are hungry to make a name for themselves, and I respect that.
I know she'll try to beat my head off, but she's never faced someone with my experience. We've trained specifically for the knockout, and I believe it can happen." If Serrano does secure the knockout, she will not only notch her 33rd career stoppage but also cement a legacy that few in any combat sport can match. The record would eclipse the 32‑KO benchmark she shares with Hall‑of‑Famer Christy Martin, giving Serrano a singular place in the annals of women's boxing.
Beyond the numbers, the fight represents a symbolic passing of the torch to the next wave of fighters who are using platforms like TikTok, Instagram and YouTube to build their brands and attract fans worldwide. At 37, Serrano is also contemplating life after boxing. While the Manzur showdown could be her swan song in the squared circle, she has hinted that she may continue to compete in mixed‑martial arts, where she already boasts an undefeated record of 2‑0‑1, including two submission victories.
"I love knockouts, but I love submissions even more," she explained. "A submission is just as satisfying, if not more, because it shows a different kind of skill.
If the right fight, the right timing and the right network come together, I might step back into the cage. I've learned a lot in MMA, and even though I haven't fought there in a few years, it would be an honour to test myself against the best and showcase what I can do with four‑ounce gloves versus the bigger MMA gloves." Serrano's potential transition to MMA is not just a footnote; it reflects a broader trend of elite boxers exploring cross‑disciplinary competition. Fighters such as Claressa Shields and Katie Taylor have already expressed interest in testing their boxing prowess in the octagon, and Serrano's success could inspire more women to pursue similar paths.
Her MMA record, though limited, shows she can adapt her striking to a grappling‑heavy environment, and her confidence in her submission game suggests she may be willing to develop that side further. The stakes for the August 21 bout are therefore multi‑layered: a 50th win, a 33rd knockout, a possible final fight in boxing, and a platform that could launch Serrano into a new chapter of combat sports. Fans can watch the fight live on TikTok, where the promotion promises a "viral moment" that could reverberate across social media.
The event also highlights the growing commercial appeal of women's boxing, as promoters seek to capitalize on the sport's rising visibility and the marketability of athletes like Serrano. Regardless of the outcome, Serrano's career has already reshaped the narrative around women's boxing.
She has captured world titles in seven weight classes, defended them against top contenders, and consistently drawn attention to the sport through her charisma and relentless work ethic. Her pursuit of the 33rd knockout is a fitting capstone to a career defined by breaking barriers and setting new standards.
If she does achieve the record, she will retire as the undisputed queen of women's knockout power, leaving future generations with a benchmark that will be hard to surpass. If she falls short, she will still walk away with a historic 50‑win tally and the respect of a sport that she helped elevate to new heights.
Either way, the world will be watching, and the fight promises to be a memorable moment in the ongoing evolution of women's combat sports.
