Mackenzie Dern vs Yan Xiaonan — Fight recap

Yan Xiaonan defeated Mackenzie Dern via majority decision over five rounds at UFC Fight Night on October 1, 2022. Xiaonan's striking superiority proved decisive, landing 113 of 195 significant strikes (57%) compared to Dern's 61 of 151 (40%), while controlling the striking exchanges throughout the bout.

Dern attempted to impose her grappling game, landing 2 of 11 takedown attempts (18%) and securing 9:19 of control time, but Xiaonan's defensive wrestling kept the fight primarily on the feet where the Chinese striker dominated. Xiaonan's leg strike volume—46 of 48 landed—systematically broke down Dern's movement and limited her ability to dictate range.

Despite the control time advantage, Dern's offensive output and takedown success rate proved insufficient against Xiaonan's volume and accuracy. The loss marked a significant setback for Dern's title aspirations in the strawweight division.
