Christina Hammer

Germany 🥊 Combat Sports

Christina Hammer was the world's best female boxer for most of the 2010s, held championships across multiple weight classes, and did it all with a professionalism and work ethic that made her the measuring stick for everyone else in the sport. The German-Kazakh fighter from Dortmund won the WBC, WBO, and IBO middleweight championships and defended them with a consistency that left no doubt about who the best was. She also happened to be building a parallel presence as one of combat sports' most photographed athletes, which she handled with the pragmatism of someone who understood that a larger platform made her sport more visible, not just her profile. Her fight against Claressa Shields in 2019 was one of the landmark moments in women's boxing history. With 389 images in her library, Christina Hammer has built a legacy that extends well beyond any championship belt.
