A missed weight added tension before the contest
Chiasson weighed 137.5 pounds, above the limit for a non-title bantamweight bout. Santos made weight at 135 pounds, and the fight proceeded after Chiasson was fined a quarter of her purse.
Inside the cage, Santos took the center early. Both women worked knees in close, with Santos pressing Chiasson toward the fence before the action returned to more open exchanges.
Clinch positioning remained a constant battle
The second round again featured lengthy periods at close range. Chiasson had stretches of fence control, but Santos prevented her from keeping the fight fixed in that position.
Chiasson also pursued takedowns and briefly brought the fight down. Santos returned to her feet, forcing the exchanges back into the standing clinch rather than allowing prolonged control on the canvas.
The final-round threat did not overturn the verdict
Chiasson found her strongest grappling position late, moving through mount as Santos rolled and exposed her back. Punches followed before Chiasson attempted a rear-naked choke across the chin.
Santos resisted the submission and reached the final horn. The unanimous verdict rewarded her overall work despite Chiasson’s closing surge, giving Santos the victory after fifteen minutes of physically demanding competition built largely around the clinch.
