As a highly accomplished and skilled professional mixed martial artist, Holly has had the distinction of competing in both the UFC's Bantamweight and Featherweight divisions, showcasing her exceptional versatility and adaptability within the octagon.
Notably, Holly made history in 2015 by becoming the Women's Bantamweight Champion, achieving a monumental upset by defeating the previously undefeated and heavily favored Rhonda Rousey, who was considered a staggering 7-1 underdog. This remarkable victory not only solidified Holly's position as a formidable force in the world of MMA, but also cemented her place in the annals of UFC title history as the biggest upset in championship title bouts.
