Amanda Serrano is preparing 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 meet Argentina’s Lucrecia Manzur, a bout that carries several layers of significance for the 37‑year‑old Puerto Rican fighter. Not only is the fight billed as a chance for Serrano to notch her 50th professional win, but it also offers a rare opportunity to break the all‑time women’s boxing knockout record.
At present, Serrano and former world champion Christy Martin share the record for most knockouts in women’s boxing, each with 32 stoppages. If Serrano can finish Manzur inside the scheduled distance, she would claim her 33rd knockout, surpassing Martin and cementing her place in the sport’s history books. Serrano has made it clear that this is the last objective she will chase in the ring.
In a recent interview with Sky Sports, the seven‑division world champion said, “This is definitely my last goal. Those little goals are what get me out of bed in the morning. They keep me motivated. This one is about breaking the record, reaching my 50th win, my final farewell fight, and that’s it.” She added that she feels she has already achieved everything she set out to do when she first laced up gloves, and that this upcoming contest is the perfect capstone to a career that has spanned more than a decade and a half.
The fight against Manzur is being promoted as a high‑profile event, with a particular emphasis on its potential to generate a viral moment on TikTok. Serrano, who has a massive following on the platform, said she wants the bout to be "a special fight for me, especially being on TikTok, where it can be a viral moment." She is confident that the 50th victory is within reach, but she is also laser‑focused on the knockout. "I guarantee the 50th win is coming, but we’re working on the 33rd knockout," she told reporters. Serrano respects Manzur’s toughness, noting that the Argentine challenger is a fellow Latina who will likely press forward aggressively.
"Manzur is a very tough fighter. She’s a Latina like me, she’s Argentinian, she’s going to come forward," Serrano said.
"The new generation of women’s boxing brings fresh energy and ambition; they want to make a name for themselves, and I know she’ll try to beat my head off. But she’s never faced someone with my experience, and we’ve been training hard for that knockout. I believe it can happen." While the fight may mark the end of Serrano’s boxing chapter, it does not necessarily signal a complete departure from combat sports. Serrano has already dipped her toes into mixed martial arts, compiling an unbeaten record of 2‑0‑1, with two wins coming by way of submission.
"I love the knockouts, but I think I love submissions a lot more," she explained. "It’s a lot more fun to get a submission than a knockout.
Who knows? With the right fight, the right timing, the right network, maybe I’ll throw some bows again." Serrano’s MMA background is modest but promising. She has not competed in the cage for a few years, yet she remains eager to test herself against top‑level opponents.
"There are a couple of good girls out there, but I don’t want to get ahead of myself. I haven’t done MMA in a couple of years, but it would be an honour to go in there with the best, just to showcase my skills," she said. She acknowledges that she still has much to learn, but she is confident that her boxing pedigree and her evolving grappling game give her a unique edge. "I’ve learned a lot throughout the years in MMA.
I’m not perfect yet, but I have these hands with four‑ounce gloves," Serrano joked, underscoring the blend of humility and confidence that has defined her career. Serrano’s legacy extends far beyond the numbers on a record sheet. She is widely regarded as one of the most decorated athletes in women’s boxing, a trailblazer who has broken barriers across seven weight classes.
Her relentless pursuit of excellence has made her a coveted opponent for up‑and‑coming fighters, many of whom view a bout with Serrano as a career‑defining moment. The upcoming fight with Manzur, therefore, carries a dual narrative: it is both a personal farewell for Serrano and a potential launchpad for the Argentine challenger’s own ascent.
The broader boxing calendar for 2026 is already packed with marquee matchups, and Serrano’s bout is expected to be one of the highlights, especially given its streaming availability through platforms that emphasize contract‑free viewing. Fans can also follow related content such as the Toe2Toe podcast, which provides weekly analysis of the sport, and a curated selection of boxing highlights and videos that capture the drama of the ring. In summary, Amanda Serrano’s August 21 showdown with Lucrecia Manzur represents a culmination of a career marked by relentless ambition, historic achievements, and a willingness to push the boundaries of what is possible for women in combat sports. Whether she secures her 50th win, lands her 33rd knockout, or simply delivers a memorable performance for the TikTok generation, the fight will stand as a testament to her enduring impact on boxing and her potential future contributions to MMA.
The world will be watching, and Serrano appears ready to give them one final, unforgettable chapter.
