Rodolfo Vieira Betting Preview

Vieira has gone 2-2 over his last four fights and is needing to find some kind of consistency here. His recent battle was a second round arm-triangle choke submission victory over Cody Brundage at UFC on ESPN 45 in April of this year.

His resume shows nine wins so far, with a knockout and eight submissions. In five of those wins, he has established a first round finish. Furthermore, he has one defeat by submission and decision.

"The Black Belt Hunter" impresses with a striking accuracy of 55 percent, though his takedown accuracy falls short at 26 percent. He maintains a rate of 3.36 significant strikes landed per minute but absorbs 4.84, resulting in a negative striking ratio.

When it comes to defense, he demonstrates a mixed performance, successfully defending against significant strikes 49 percent of the time and achieving a perfect 100 percent takedown defense rate. In terms of grappling, he attempts an average of 3.70 takedowns and secures 1.42 submissions per 15 minutes of fight time on the ground.

Armen Petrosyan Betting Preview

Petrosyan has won his last two fights coming into this matchup. His previous successful bout was a unanimous decision over Christian Leroy Duncan back at UFC on ESPN 47 in June earlier this year.

Looking at his nine wins, he has six knockouts and three decisions. Three of his knockouts have resulted in first round finishes. Of his two losses, he has one each by knockout and decision.

“Superman” showcases a 53 percent striking accuracy and a 33 percent takedown accuracy. His significant strike ratio is in the positive range, delivering 5.97 significant strikes per minute while absorbing 3.03. This will ultimately be the difference in this fight.

On the defensive side, he maintains a 57 percent success rate against significant strikes but exhibits vulnerability with a 37 percent defense against takedowns. Additionally, he averages 0.23 takedowns per 15 minutes of action, so do not expect him to show dominance here.
