Mayer (17-0, 5 KOs), 32, of Woodland Hills, California, won the then vacant WBO belt with a unanimous decision victory over Ewa Brodnicka in October 2020. She added the IBF belt by defeating Maiva Hamadouche also by unanimous decision 11 months ago. Mayer defended the belts in April against Jennifer Han.

Baumgardner (12-1, 7 KOs), 28, of Fremont, Ohio, flew to Sheffield, England and stop Terri Harper in Round 3 to win her title in November 2021. In April she defended the belt in a a unanimous decision win over Edith Soledad Matthysse.
