2012-06-20 Kazuto Ioka w pts 12 Akira Yaegashi, Bodymaker Coliseum, Osaka, Japan - WBC/WBA
After Ioka relinquished the WBC title on 29 June, being unable to defend both belts within the same time frame, a fight between Xiong Zhao Zhong and Javier Martinez Resendiz was organised to find a successor. Eventually, on 3 October, after it was announced that Ioka would be moving up to junior flyweight, Ryo Miyazaki was matched against Pornsawan Porpramook to contest the vacant WBA title.
On 14 July, Jesus Silvestre outpointed Edwin Diaz over 12 rounds at the Fair Stockade, Tepic, Nayarit, Mexico, to win the vacant WBA ‘interim’ title. Silvestre then made a successful defence of the WBA ‘interim’ title when stopping Takuya Mitamura inside four rounds at the same venue on 6 October.
