At the end of five rounds of the match, the judges with a score of 47-48 and 48-47 twice gave the victory to the Brazilian, who dealt heavier blows, and in the second round she was close to an early victory, almost strangling the American in the rack.
Holly Holm, who has traditionally relied on work in the clinch, expressed her disagreement with the judge's verdict, saying that she was robbed.
"I think I won the fight," The Preacher's Daughter said in an interview with Daniel Cormier. “I gave her the second round, but I feel like I took all the others. I could have done everything more perfectly, but I have no doubt that I won. It's not a question for me."
Vieira, who has won a second straight win, has made it clear that she wants to see the winner of the title fight between Julianna Peña and Amanda Nunes as her next opponent, who will headline UFC 277 on July 30.
"I'm here and I'm ready," said the Brazilian.
In the second most important event of the tournament, Brazilian welterweight Michel Pereira extended his winning streak to five matches, in a spectacular three-round confrontation with a score of 29-28, 30-27 and 28-29, winning a split decision against Argentina 's Santiago Ponzinibbio .
Chidi Njokuani, Joseph Holmes, Zhailton Almeida, Urosh Medich, Chase Hooper and Sam Hughes were noted for early victories this evening.
