Claressa Shields W10 Ema Kozin... In Cardiff, Wales, Claressa “G.W.O.A.T.” Shields successfully defended her WBC/WBA/IBF middleweight world titles Saturday night with a unanimous decision victory over Ema Kozin (21-1-1) in Cardiff, Wales. Shields (12-0) dominated the action on her way to a clean sweep on the judges’ scorecards, with all three seeing the fight 100-90 for boxing’s only [former] two-division undisputed champion. With WBO middleweight champion Savannah Marshall ringside [and indicating disrespect], Shields moved one step closer to a grudge match against Marshall later this year. Marshall owns an amateur victory over Shields, the only boxing defeat Shields has ever suffered in the amateur or pro ranks.
