It didn’t take long for Meng Bo to launch her introduction to ONE Championship fans Saturday. In her long-awaited promotional debut, after having two previously scheduled fights against two-time title challenger Mei Yamaguchi scrapped, Bo (14-5) took out former title challenger Laura Balin (11-6) with relative ease in the top MMA fight at “ONE Championship 103: Age of Dragons.” Balin held her own in the opening minute of the fight, coming at Bo. But when Bo landed a big overhand right, Balin quickly dropped to the canvas.
