Barb Honchak made her second successful defense of the Invicta Flyweight Championship last night at Invicta 9, earning a decisive five-round unanimous decision victory over Tayako Hashi.

Fighting in her home state of Iowa, Honchak used a grinding style to keep the belt — the fourth straight win for Honchak by unanimous decision. Tokyo, Japan’s Hashi, who had only won two of her last six bouts, was game but mostly helpless against the American’s slow, clinch-heavy attack.

In the co-main, Mizuki Inoue, who was announced as simply Mizuki on the UFC Fight Pass broadcast, was defeated by Karolina Kowalkiewicz via split decision in their strawweight bout. Japan’s Mizuki, only 20, is one of women’s MMA’s rising stars but struggled with a reach disadvantage in the fight’s standup exchanges — along with the Pole’s torrid pace.

Raquel Pa’aluhi’s come from behind win over Kaitlin Young was a highlight of the undercard. The Hawaiian, a late replacement, gutted through a tough first round where she was out-struck and bloodied by Young. Pa’aluhi eventually earned the takedowns, groundwork, and strikes she needed to earn a unanimous decision victory in the featherweight affair.
