The promotion has been releasing a countdown of the Top-100 fights ever, reaching No. 1 recently.

In the top spot sits a battle between Aung La N Sang and Ken Hasegawa for the middleweight title at ONE: Spirit of a Warrior.

The card took place this past June from the Thuwunna Indoor Stadium in Yangon, Myanmar. It was the first defense for the Myanmar hero, as he came out on top with a fifth round finish via strikes over Hasegawa.

ONE Championship was created in 2011 by Chatri Sityodtong and Victor Cui. Events are broadcast to over one billion homes in 128 countries and have held almost 80 cards in Jakarta, Manila, Kuala Lumpur, Dubai, Taipei, Phnom Penh, Beijing, Guangzhou, Yangon, Changsha, Hefei, Macau and Bangkok as well as Singapore.
