Saen Sor Ploenchit vs. Hiroki Ioka, billed in Thailand as Khu Muay Haeng Totsawat (Thai: คู่มวยแห่งทศวรรษ, "Fight of Decade"), was a professional boxing match contested on October 17, 1995, for the WBA flyweight championship.

[1] This was also his second attempt at the flyweight world title, having lost his first by TKO to the crown holder David Grimán in June 1993.

In the middle of the round, while both were fighting at close range, Saen landed several left and right punches to Ioka's face, causing him to fall to the ring floor and lie on his back.

When the referee Mitch Halpern counted to eight, he allowed the fight to continue, but Ioka lost his balance and staggered backwards.

However, the fight never happened until Saen unexpectedly lost the title to Venezuelan José Bonilla late the following year, and never came back as a champion again.
