Even the mightiest do fall, especially in combat sports.

There is a new queen atop the Ultimate Fighting Championship’s women’s strawweight division, and her name is Rose Namajunas.

The heavy underdog heading into her championship match against undefeated Joanna Jedrzejczyk, Namajunas tagged the former titlist early in the bout and kept up the pressure throughout, eventually earning a knockout/technical knockout finish at the 1:55 mark of the first round of their title fight at UFC 217 at Madison Square Garden in New York City.

After exchanging leg kicks and jabs with Jedrzejczyk in the opening moments of the bout, Namajunas landed an overhand right that caught the defending champion on the jaw early in the first round. Although Jedrzejczyk held guard and got back to her feet, it did not last long.

Namajunas continued to push the pace from the center of The Octagon and floored Jedrzejczyk with a left hook and followed with an overhand right to her downed opponent. After firing another left hand, Namajunas threw three straight rights before finishing the bout with five consecutive lefts prior to the stoppage.

Namajunas landed 18 of her 37 strike attempts, including 15 significant shots. Jedrzejczyk connected on just five strike attempts, according to FightMetric.

With the win, Namajunas improved to 8-3-0 in her professional career, while Jedrzejczyk fell to 14-1-0 in what was her sixth defense of the UFC women’s strawweight championship.

Now, Namajunas has won five of her last six fights and scored her first career knockout in the UFC with the victory over Jedrzejczyk.
