Joanna Jedrzejczyk has laid waste to an entire division in three short years, and she shows no signs of slowing down. The Polish powerhouse will celebrate her 30th birthday on Aug. 18.

Jedrzejczyk arrived on the Ultimate Fighting Championship scene as an undefeated but unproven prospect in July 2014 and went on an absolute tear at 115 pounds. After victories over Juliana Lima and Claudia Gadelha made her the No. 1 contender, she captured the women’s strawweight championship with a brutal beatdown of Carla Esparza at UFC 185. Jedrzejczyk has only tightened her grip on the throne since, as she emerged as the top pound-for-pound fighter in women’s MMA. Now operating out of American Top Team in Coconut Creek, Florida, “Joanna Champion” has successfully defended the 115-pound title on five occasions, besting Gadelha in their rematch, Jessica Penna, Valerie Letourneau, Karolina Kowalkiewicz and Jessica Andrade. In those five appearances, Jedrzejczyk has outlanded the opposition by an eye-popping 994-406 margin, per FightMetric.

Her perfect record now at 14-0, Jedrzejczyk figures to put her championship on the line once more in 2017, perhaps against Rose Namajunas.
