Claressa Shields vs. Christina Hammer highlights recap. Claressa Shields has been referring to herself as the "G.W.O.A.T." (Greatest Woman of All Time) for quite some time now. Well, she can speak the nickname into existence that much further by becoming the undisputed middleweight champion of the world. Shields (8-0, 2 KOs), the WBA, WBC and IBF champion, will look to do that Saturday night when she faces Christina Hammer (24-0, 11 KOs), the WBO titleholder, inside the Adrian Phillips Theater at the Boardwalk Hall in Atlantic City, N.J., with all the titles and the Ring and lineal straps on the line, live on Showtime. In late February, Sporting News asked Shields if becoming just the second female boxer to be crowned undisputed champion (Cecilia Braekhus is the current undisputed welterweight champion) would rank higher than her two Olympic gold medals. The Flint, Mich., native had to give the nod to owning all the middleweight gold. "I have to rank the undisputed higher," Shields said, "but my two Olympic medals are right there." Shields added that she upped her cardio in preparation for Hammer because she fully expects the German boxer to take off running once she feels her power. "I know the first couple of rounds, she may try to stand there, but after she feels the power, she’s going to take off," Shields said. "And once she takes off, these legs got to be ready to go." That being said, Hammer figures to be Shields' toughest opponent to date. She has enjoyed a long reign as champion and will enter the ring Saturday night as confident as Shields. "I want to show America who Christina Hammer is," Hammer told SN earlier in the week. "My goal is to finish her and become the undisputed women’s middleweight champion." Will Shields add a page to her growing legend by becoming the undisputed champion of the world, or will Hammer prove that she's the real deal?
