Amanda Serrano defeats Lucrecia Manzur to retain featherweight titles

Amanda Serrano retained her WBA and WBO featherweight belts with a narrow majority decision over Argentina's Lucrecia Manzur in the first world title fight to be streamed live on TikTok.

The Puerto Rican was made to work for her 50th career win, edging a majority decision but missing the 33rd knockout she needed to break the women's record, remaining on 32.

Serrano's fight, held over 12 two-minute rounds, may not have delivered a record‑breaking knockout, but it drew 3.4 million total views on TikTok.

The 37-year-old continues to be one of the most watched female fighters in the world, with her third fight against Ireland's Katie Taylor last year drawing an audience of six million on Netflix and their rematch in 2024 getting over 50 million on the same platform.

Friday's fight in Temeculam, California was scored 114-114, 116-112 and 116-112 in favour of Serrano.

Manzur troubled the champion early with repeated right hands, but the Argentine tired as Serrano seized momentum from round nine and finished the fight in control.

Speaking after the bout, Serrano said: "I am so happy and honoured. That was the first championship main event fight on TikTok guys, super excited, super honoured."

On Manzur, Serrano added: "I knew this girl was tough. She's young. She's 27. She's 10 years younger than me. These girls are getting younger and stronger."

"She was hungry, and I knew that coming into training. I trained very hard because I knew it was an opportunity for her, so I had to come on my A game."

The unified champion will now be hoping to eclipse Christy Martin with a 33rd stoppage in her farewell fight, which she plans to stage in Puerto Rico later this year or in early 2027.

Martin was ringside for the contest, saying: "No matter what, I'm always in [Serrano's] corner."

Serrano's record now stands at 50 wins, four losses and one draw, while Manzur slipped to her fifth career loss in 19 bouts.
