Two-time Olympic gold medalist Claressa Shields (9-0, 2 KOs) can now add a new accomplishment to her resume, as she became the Undisputed Middleweight Champion of the world following her unanimous decision win over Germany’s Christina Hammer Saturday night in Atlantic City.

The judges scored the fight 98-92, 98-91, and 98-91.

“I am the greatest woman of all time,” said Shields. “I did it. She didn’t win a single round.  I almost knocked her out. I swear I feel like I’m dreaming right now. Thanks to Christina Hammer and her team. They said she had a hard jab and they weren’t lying. Her jab is off the chain."

Shields, 24, entered the bout holding the IBF, WBA, and WBC 160-pound titles.  She showed off her complete arsenal of skills in a dominant performance, joining Terence Crawford, Jermain Taylor, Bernard Hopkins, Oleksandr Usyk, and women’s welterweight champion Cecilia Braekhus as the only fighters to have unified all four major world titles in any weight class.

“I was just calculating in the first round and after that I started picking her apart,” said Shields. “I knew I could hurt her. I thought I finished her in round eight. I thought the fight should have been stopped.  She was holding onto me.  I just told myself, stay cool, stay cool.  I was trying to get the perfect punch to get her out of there.”

Christina Hammer (24-1, 11 KOs), who owned the WBO belt entering the fight, had her jab largely neutralized and her defense exploited throughout the fight. Shields landed a remarkable 44% of her power punches, as she set those shots up effectively by doubling and tripling up on her jab.

“I didn’t fight very good or fast,” said a subdued Hammer. “That’s boxing, anything can happen. I wanted this fight. She won, respect to her. She’s a tough, strong woman and that’s all I can say."

Shields’ defense was also excellent, as Hammer was able to connect on just 13 percent of her total punches, 11 percent of her jabs, and 18 percent of her power shots.

“She’s fast, she comes forward," said Hammer. "She has fast hands. I couldn’t land my jab as good as I expected."

Fresh off the biggest win of her professional career, the newly-crowned undisputed champion of the world already has her sights set on another opponent.

“Give me Cecilia Braekhus at 154 pounds," said Shields.  "That’s who I want next. Either her or Savannah Marshall.”

In the co-featured bout, heavyweight prospect Jermaine Franklin (18-0, 13 KOs) kept his unbeaten record intact with a 10-round unanimous decision over former No. 1-ranked U.S. amateur Rydell Booker (25-2, 12 KOs). The judges scored the fight 99-91 and 98-91 twice.

The 25-year-old Franklin dictated the tempo throughout and was far more active and aggressive than his 38-year-old counterpart. Booker had his moments, particularly in the early rounds when he landed several flush power shots, but the youthful Franklin pulled away in the second half of the fight as Booker tired and Franklin targeted the body. Franklin averaged 54 punches per round to Booker’s 35, and led 146-94 in overall punches landed.

“I think I had a decent performance,” said Franklin. “There’s some stuff I could work on. I over-crowded myself a little bit and I was a little over-anxious. He had a lot more experience than me and used it to his advantage. He could see what I was doing."

Booker did not disagree entirely with the decision.

“I felt he out-hustled me, but it was a lot closer than how the judges scored it,” said Booker. “He was missing me a lot more than it looked. I slipped a lot of shots and hit him clean.  I knew he would bring the pressure, but he needs a lot of work. He stays too centered with his head. He's alright. What he has on his side is youth. I'd rate my performance about a seven. I had a training camp injury I was dealing with.”

In the Showtime telecast opener, undefeated top-five ranked heavyweight prospect Otto Wallin (20-0, 13 KOs, 1 ND) and Baltimore’s Nick Kisner (21-4-1, 6 KOs, 1 ND) had their 10-round bout cut short when the two heavyweights clashed heads in the opening round. Wallin suffered a gash on the side of his head while Kisner suffered a cut over his right eye, hindering his ability to see. At the advice of the ringside physician in between rounds one and two, referee Earl Brown stopped the fight, resulting in a no-decision.

“To me, his cut didn’t look that bad,” said a disappointed Wallin, who was making his U.S. debut. “It’s a shame because I trained really hard for this fight and was looking to put on a show for fans in America. I just didn’t have time to get going."
