Amanda Serrano Eyes History and TikTok Milestone in Penultimate Career Fight.

Seven-division world champion Amanda Serrano is set to defend her WBA and WBO featherweight titles against Argentina’s Lucrecia Manzur in the first world title boxing event live-streamed on TikTok.

A 33rd stoppage win would see the 37-year-old Puerto Rican icon surpass pioneer Christy Martin for the most knockouts in women’s boxing history, while marking her 50th professional victory. The bout serves as the penultimate appearance of Serrano’s historic career ahead of her planned farewell fight in Puerto Rico.
