In the main event, two-time U.S. Olympic Gold Medalist Claressa Shields (12-0, 2 KOs), the WBC/WBA/IBF/Ring Magazine middleweight champion aims to, once again, become the undisputed champion at 160 pounds. She will face WBO titleholder Savannah Marshall (12-0, 10 KOs), one of the sport’s most devastating knockout artists. Marshall handed Shields an amateur defeat in 2012, the only time Shields has been toppled as a pro or amateur.

In the title unification co-feature, Mikaela Mayer (17-0, 5 KOs) will look to get one step closer to becoming the first undisputed champ in her division when she puts her WBO/IBF/Ring Magazine junior lightweight titles on the line against bitter rival and WBC champion Alycia Baumgardner (12-1, 7 KOs). Mayer, a 2016 U.S. Olympian from Los Angeles, is a 2022 ESPY Award nominee and ranks as one of the sport’s elite pound-for-pound practitioners. Baumgardner, from Fremont, Ohio, became a world champion last year when she knocked out local favorite Terri Harper in Sheffield, England.
