Amanda Nunes retires after blowout win over Irene Aldana at UFC 289

Amanda Nunes is leaving MMA at the peak of her powers.

The UFC’s only current two-division champion announced her retirement on Saturday, walking away on top after adding another flawless title defense to her résumé in UFC 289’s main event. For her swan song, Nunes dominated Irene Aldana to win a lopsided unanimous decision and notch the sixth defense of her bantamweight belt over her two title reigns. All three judges scored the bout a clean sweep in Nunes’ favor, 50-44, 50-44, 50-43.

It was one final flawless performance for Nunes (23-5), who reasserted her dominance over the women’s 135-pound division all over again by battering Aldana for all five rounds.

The champ was never once in trouble, overwhelming a tentative Aldana with a mix of standup acumen and mat wizardry. Nunes out-landed the Mexican talent 142-41 in significant strikes, won the takedown battle 6-0, and connected on 53 percent of her significant strike attempts compared to Aldana’s paltry total of 28 percent.

Aldana’s best shot came early in the first round when she cracked Nunes with a well-timed counter right hand, however the future Hall of Famer just ate it and continued her assault.

Nunes, 35, now exits MMA as the most decorated female fighter in UFC history and one of the most decorated champions to ever lace up a pair of four-ounce gloves, regardless of gender.
