Amanda Serrano Teases Retirement After Making History, Full Judges' Scorecards & Reaction from Win

Amanda Serrano was unable to break the record for most knockout wins by a female boxer, but she still made history with her 50th career win over Lucrecia Manzur on Friday night.

Serrano, who was defending the WBO and WBA featherweight titles, held on for a majority decision victory against Manzur that the judges scored 116-112, 116-112 and 114-114.

ESPN's Michael Rothstein noted the 50-win milestone is "a benchmark that few women's fighters have reached."

Even though Serrano got the win, she acknowledged the impressive showing by Manzur.

"A tough, young fighter. She was hungry," Serrano said in the ring. "And I knew that coming into training."

In a post on X following the event, Serrano also hinted that this could be the last fight of her storied career.

Serrano entered the fight with 32 career knockout wins, tied with Christy Martin for the most ever by a women's boxer.

Even though Serrano was unable to surpass Martin's KO mark, the win did move her ahead of the Hall of Famer in the victory column. Martin finished her legendary career with a 49-7-3 record.

"We still got that 33rd knockout [to try for]; I've got one more fight," Serrano said after the fight (h/t Rothstein). "If I don't get it, I'm glad that I tied with Christy Martin."

The fight was much closer than anticipated with Manzur having a strong argument as the winner.

Serrano landed more total punches (168-164) and power punches (142-118), but Manzur was more efficient overall with a 33.9 percent hit rate on total punches compared to 24.9 percent for the champ.

Manzur landed more total strikes in seven of the 12 rounds, but Serrano connected on more power punches in seven rounds, including each of the last four rounds.

This was just the second time in Serrano's career she won a fight by majority decision. The only other time it happened was her first professional bout against Jackie Trivilino in March 2009.

Serrano has a recent loss by majority decision against Katie Taylor in July 2025 in the final fight of their historic trilogy. The 37-year-old has rebounded with three consecutive victories since that defeat.

If this does end up being the last fight of Serrano's career, she will go down as one of the most accomplished boxers in the history of the sport. Her accolades include a Guinness World Record for winning world titles in seven different weight classes.
