About Macy Chiasson
Size and physicality in a division with few equals
Macy Chiasson won The Ultimate Fighter 28 competing at featherweight and later settled mainly at 135 pounds. Her size remains one of the hardest traits to replicate in women's bantamweight.
Fighting style
Standing around 1.80 meters, Chiasson can use knees, the clinch and long strikes from distances many opponents are not used to managing. She also has enough of a grappling base to turn her size into control when she gets top position.
Recent results
Wins over Pannie Kianzad and Mayra Bueno Silva took her to important positions in the rankings, although she then lost to Ketlen Vieira, Yana Santos and Ailín Pérez in a row. Her physique still gives her tools that are unique in the division.
