Seo Hee Ham edged out two-out-of-three scorecards against Ayaka Hamasaki on Tuesday, making her the new RIZIN Super Atomweight Champion. The win was on the top half of RIZIN 20, at Saitama Super Arena in Saitama, Japan.

Ham was crowned the new champion after three rounds of competition. The most impactful round from Ham was the second one, where she landed dozens of elbows on the ground.

Hamasaki became the RIZIN Super Atomweight Champion on New Year’s Eve last year, defeating Kanna Asakura. She defended her belt once since then, going to the scorecards against Jinh Yu Frey in a rematch.

Earlier on the RIZIN 20 card, Jiri Prochazka defended his Light Heavyweight Championship against former-UFC fighter C.B. Dollaway.
