Since October 2020, Savannah Marshall, a British professional boxer, has held the WBO female middleweight championship. She won gold in the 2012 World Championships and, as an amateur, became the first British woman to win a world championship. Due to her shyness, she was given the nickname "Silent Assassin." She is currently ranked by BoxRec as the second-best active female middleweight in the world and by The Ring as the fifth-best active super-middleweight as of October 2020. Claressa Shields, the middleweight women's Olympic gold champion from 2012, has never been defeated by a boxer before. Savannah is the sole exception.
