On paper, and in the ring, it was a mismatch though sadly it was a mismatch courtesy of various out of the ring issues. Originally Aoki was supposed to fight Indonesia's Roy Mukhlis, a former world title challenger. Mukhlis was replaced by Terdsak Kokietgym who in turn replaced by Ekayut with about a week's notice.
In his previous 2 bouts Aoki had been fighting in the Philippines so there was next to no chance he was going to be dropped from what was his "home coming" performance, especially in his home city of Osaka.
The hard hitting Japanese fighter announced after the fight that he would be back in the ring in December defending his WBC Asian Boxing Council Lightweight title. We're assuming that will mean he's back on the round, likely in the Philippines again, due to the fact the JBC don't appear to recognise the title.
