Mikaela Mayer’s highest-profile fight will have to wait. As much as Mayer might want to test herself against former U.S. Olympic teammate and her “sister,” Claressa Shields, she is fully focused on securing a shot at accomplishing something Shields has done in three weight classes. Now that she defeated England’s Sandy Ryan more decisively in their 10-round rematch, Mayer has turned her attention toward a showdown with another welterweight based in the UK, Welsh southpaw Lauren Price.
