Katie Taylor, Claressa Shields and Amanda Serrano continue to lead the way in the ESPN women’s pound-for-pound rankings.
But Mikaela Mayer gained some ground and solidified her spot in the top 5 with a dominant unanimous decision victory over Maiva Hamadouche to unify the WBO and IBF junior lightweight world titles.
In a back and forth fight, Mayer (16-0, 5 KOs), 31, of Woodland Hills, California won by the scores of 100-90, 99-91 and 98-92 in the Top Rank on ESPN main event at Virgin Hotels Las Vegas on Nov. 5.
ESPN writer Michael Rothstein moved Mayer up one spot after the victory, saying Mayer looked impressive against Hamadouche.
“Against her toughest opponent to date, Mikaela Mayer looked her best — and took her fighting to another level,” Rothstein said of Mayer’s performance. “She showed she could win, and be technically smart, in a brawling fight in addition to her usual boxing repertoire.
“It was a fight where Mayer’s growth was too evident to ignore. Nothing against lightweight Delfine Persoon, who also won last week, but at this point Mayer looks like a superior fighter. So I flipped them on my list. Hopefully that’s a fight we see down the road, perhaps after Mayer becomes undisputed in her division if she’s able to do so.”
Another fighter making a move is Savannah Marshall, who defended her WBO middleweight title recently to move into the top 10.
Marshall (11-0, 9 KOs), 30, of Hartlepool, England, defeated Lolita Muzeya (16-1, 8 KOs), 30, of Mwinilunga, Zambia by second-round TKO to stay unbeaten. Marshall is scheduled to return to the ring on Dec. 11 when she will share a boxing card with Shields to set up a megafight between both champions early next year.
