5 biggest UFC fights of Ronda Rousey's career

#2. Ronda Rousey vs. Amanda Nunes - UFC 207

Nunes defeated Rousey on December 30 2016

Ronda Rousey and Amanda Nunes have been arguably the two biggest names in the UFC women's divisions since their inception. These two all-time greats fought at the end of 2016 in what appears to be the last professional MMA fight in Rousey's illustrious career.

Nunes entered the fight on a four-fight winning streak and had just claimed the bantamweight championship against Meisha Tate last time out. Rousey, on the other hand, was coming off the first loss of her career and was looking to get back on track.

The highly anticipated fight was over very quickly when Nunes secured a TKO victory after just 48 seconds in the first round. She continued to dominate the competition, winning seven more fights before her recent upset loss at the hands of Julianna Peña.

#1. Ronda Rousey vs. Holly Holm - UFC 193

Holm defeated Rousey on November 15 2015

While both of Ronda Rousey's fights with Amanda Nunes and Holly Holm sold a reported 1,100,000 pay-per-view buys, it is this bout that takes the top spot. Both women came into this one undefeated and Rousey had an enormous following at this point, having secured a first-round finish in each of her last four fights.

Holm was also undefeated but had an admittedly less impressive run of form going into the fight. She had had just two UFC bouts prior to her clash with Rousey and while she had won both, one split decision and one unanimous decision hardly suggested she was about to pull off the unthinkable.

Things got heated prior to the bout when Rousey taunted her opponent and even refused to touch gloves with Holm.

Ultimately, it was Holm that shocked the world with an upset KO victory in the second round. This was one of the biggest upsets in UFC history and, while it was one of the rare occasions that didn't go in her favor, it may have been the biggest fight of Rousey's MMA career.
