Amanda Serrano has announced that she wants to add one more historic milestone to her already legendary boxing résumé before she hangs up her gloves for good. The current unified feather‑weight champion will step into the ring against Argentina’s Lucrecia Manzur on August 21 in California, a bout that not only offers her the chance to notch her 50th professional win but also provides the opportunity to break the all‑time women’s boxing knockout record.

At present, Serrano shares the knockout crown with Christy Martin, each boasting 32 stoppages. If she can finish Manzur inside the scheduled distance, she would claim her 33rd career KO and become the outright record‑holder. Serrano, a seven‑division world champion, told Sky Sports that this objective is "definitely my last goal." She explained that setting small, attainable targets is what drives her daily training routine, and this final ambition—securing the 50th victory and the 33rd knockout—represents the ultimate farewell.

"I feel I have already achieved everything I set out to do when I first entered the sport," she said, adding that she is ready to close this chapter on a high note. The upcoming fight has attracted considerable buzz, especially because it will be streamed on TikTok, a platform that could turn the contest into a viral moment.

Serrano acknowledges the significance of the digital audience and is confident that a knockout would generate massive online reaction. "This fight is special to me because it’s on TikTok, and a knockout could become a huge viral clip," she explained. "I’m certain the 50th win is coming, and we’re working hard for that 33rd knockout." Manzur, a tough Latina fighter from Argentina, is expected to bring an aggressive style, aiming to "beat Serrano’s head off," as the Puerto Rican champion put it.

Serrano, however, believes her experience and skill set give her the edge. She highlighted the evolution of the newer generation of female fighters, noting that they are entering the sport with a desire to make a name for themselves and often bring fresh approaches. "She’ll try to come forward and land big shots, but she’s never faced someone with my depth of experience," Serrano said.

"We’ve been training specifically for a knockout, and I trust it can happen." Beyond the immediate stakes, the bout could signal the end of Serrano’s boxing career. Yet the 37‑year‑old has hinted that retirement from the squared circle might not mean a complete departure from combat sports.

She has already dipped her toes into mixed‑martial arts, compiling an undefeated record of 2‑0‑1, with two wins by submission. "I love knockouts, but I enjoy submissions even more.

Getting a tap‑out feels more fun than a knockout," Serrano remarked. She left the door open for a possible return to MMA, saying that with the right opponent, timing, and promotional backing, she could step back into the cage.

"I haven’t fought in MMA for a few years, but it would be an honor to test myself against top talent and showcase what I’ve learned," she added. Serrano’s career is already studded with achievements: she holds world titles in seven weight classes, has amassed 50 professional victories, and is on the brink of setting a new knockout record. Her legacy is further cemented by her role as a trailblazer for women’s boxing, inspiring a new wave of fighters who look up to her as a benchmark of success.

The upcoming fight against Manzur therefore carries both personal and symbolic weight. It offers Serrano a chance to finish her boxing journey on her own terms, while also providing a platform for the next generation to witness a potential historic moment.

If Serrano succeeds in stopping Manzur before the final bell, she will not only celebrate her 50th win but also become the undisputed leader in women’s boxing knockouts with 33 stoppages. That achievement would eclipse Christy Martin’s long‑standing record and solidify Serrano’s place at the very pinnacle of the sport’s history. Even if the fight goes the distance, reaching the 50‑victory milestone would still be a remarkable capstone to an extraordinary career.

Regardless of the outcome, Serrano’s determination, professionalism, and willingness to embrace new challenges—whether in the ring or the octagon—underscore her status as one of the most versatile and accomplished combat athletes of her era. Fans and analysts alike will be watching closely on August 21, eager to see whether the Puerto Rican champion can deliver the knockout that would seal her legacy and perhaps signal the final chapter of an unparalleled boxing saga.
