In a captivating grappling chess match, Ayaka Hamasaki was just a little bit craftier than Amber Brown.
Hamasaki (13-1, 3-1 Invicta) retained her atomweight title in the Invicta Fighting Championships 16 headliner at Trinidad Pavilion at Tropicana Las Vegas on Friday night, submitting Brown (6-2, 3-1 Invicta) with an armbar at the 2:52 mark of round three. Brown did not go quietly however, as she fought off multiple submission attempts from her Japanese opponent before finally succumbing.
After Brown landed a takedown early in round three, Hamasaki used a kimura to sweep to top position.
