Ayaka Hamasaki was pushed to the limit in her rematch against Kanna Asakura , but did just enough to earn the split-decision verdict from the ringside judges as she retained her Rizin FF super atomweight title by the slimmest of margins in Nagoya, Japan. Hamasaki’s title bout with Asakura was the main event of Rizin FF 27, and saw the champion hang on to title after a grueling three round battle at Nippongaishi Hall. After the fight was paused in the opening seconds for an accidental low blow, the action resumed with both women engaging in a wild exchange that eventually saw the action move to the canvas, with the champion on top. Hamasaki (22-3) landed a pair of powerful knees to her downed opponent, but Asakura (18-5) showed her grit by battling to her feet, before picking up the champion and slamming her powerfully into the canvas. Round 2 saw Asakura push the pace as she forced Hamasaki onto her back and set to work from the champion’s guard. But Hamasaki defended well and threatened with an armbar off her back before eventually escaping and returning to her feet.
