Smilla Sundell becomes the youngest world champion in ONE Championship history

Smilla Sundell claimed the biggest win of her young career and earned a place in the history of ONE Championship in April 2022.

Sundell battled Jackie Buntan for the inaugural ONE women’s strawweight Muay Thai world championship in the co-main event of ONE 156. The Fairtex product maximized her reach advantage throughout the contest, dominating the Filipino-American on her way to a unanimous decision victory.

With her win, she became the youngest world champion on the promotion’s deep roster.

By claiming the world title at 17 years and five months, Sundell took the honor held by ONE women’s atomweight world champion Angela Lee.

Lee won the inaugural atomweight crown in 2016 when she was 19 years and nine months old. At the time, she was the only teenage world champion in the promotion.
