ONE Championship: Step by step, immediate contender Martyna Kierczyńska has grand plans to dominate strawweight division
- Things have happened very fast for the 21-year-old Polish fighter, who stepped up at short notice to beat Nat “Wondergirl” Jaroonsak last month
- Her reward was a performance bonus and a bout this weekend against Ekaterina Vandaryeva that she hopes to win on her journey to the divisional title

Martyna Kierczyńska stepped up at short notice last month to beat Nat “Wondergirl” Jaroonsak at ONE Fight Night 19. The reward for the Polish strawweight has been a fast turnaround and another bout this weekend, against Ekaterina Vandaryeva at ONE Fight Night 20.
Things have happened very fast for the 21-year-old. The win against “Wondergirl” was a watershed moment for Kierczyńska, picking up a US$50,000 (HK$390,000) performance bonus and establishing herself as an immediate contender in the division.
Kierczyńska told the Post it was the perfect way to start her ONE Championship career.
“I was so happy, it was my dream debut. Even better than I thought it would be.”

Former UFC champions Jan Błachowicz and Joanna Jędrzejczyk, both also from Poland, praised her after the win over Jaroonsak and Kierczyńska was delighted to receive this recognition.
