Tina Rupprecht will face Japan’s Sumire Yamanaka in Germany for the unification of the WBC, WBO, IBF and WBA atomweight (102-pound) titles. The bout will take place on April 5th at the MBS Arena in Potsdam, Germany. Rupprecht is a two-division champion, having won the WBC 105-pound title in 2018 by defeating Niorkis “Bachaca” Carreno by unanimous decision. After four successful defenses, she was defeated by American Seniesa Estrada. The German Rupprecht then moved down a division to fight for the WBC atomweight title, defeating the Czech Fabiana Bytyqi to become the champion. Last year, Rupprecht added the WBA and WBA titles by defeating Eri Matsuda. Yamanaka, from Japan like Matsuda, is undefeated and holds the IBF world title, having beaten Mika Iwakawa for her title in 2024.
