5 AMANDA SERRANO
IT is baffling how Puerto Rico’s Serrano manages to leap around the weight classes. In 2018 she was boxing and winning world honours at superlightweight. By January of this year she dropped all the way down to super-flyweight to knock out Eva Voraberger for the vacant WBO title at Madison Square Garden. But in September she was up at featherweight to outpoint New Yorker Heather Hardy for another WBO crown at MSG once again.
