Michelle Waterson dominated media coverage leading up to Invicta FC 8 — clearly being positioned as the face of the promotion, which made its debut broadcast on UFC Fight Pass last night.

Last night in the Invicta 8 main event, she similarly dominated her opponent, earning a one sided TKO victory to retain her Invicta FC Atomweight Championship.

Waterson was in control from the opening bell, scoring punches, knees, and kicks to head and body of the over-matched Yasuka Tamada. The end came, mercifully, at 4:58 of round three, as referee Greg Franklin called off the bout after a series of Waterson punches.

Waterson, of Colorado but fighting out of Greg Jackson’s academy in New Mexico, advances to 12-3 in her career. Tamada, of Toyko, Japan, falls to 15-9-3.

In the Invicta 8 co-main, Katja Kankaanpää of Finland came from behind to defeat Stephanie Eggink of the US. Eggink had landed solid strikes in the opening rounds, particularly the end of the first. But Kankaanpää hung tough, scoring a D’Arce choke in a transition in the fifth. The Finn earns the vacant Invicta FC Strawweight Championship.
