Instead, the Brazilian fighter crashed the UFC 200 party. Nunes demolished Tate in the main event at T-Mobile Arena, winning via rear-naked choke Saturday night and claiming the championship. The time of the stoppage was 3:16.
The beginning of the end came when Nunes landed a head kick following a scramble. She then opened up with crisp technical striking, landing lefts and rights as she bloodied and wobbled Tate.
Tate, who had trouble making weight on Friday, covered up on the ground as Tate continued raining down punches. She sunk in a rear-naked choke, causing Tate to tap and giving Nunes her 10th career finish.
"I'm the champion," said Nunes (13-4), who won her fourth straight fight. "Oh my god, the greatest moment of my life I feel amazing."
Tate (18-6), who is also a former Strikeforce champion, had her three-fight winning streak snapped.
"She's very fast, very dangerous, and she caught me fair and square," Tate said. "I got careless and she made me pay for it."
