• The Action: Both fighters traded heavy leather early. Oliveira capitalized on his long reach, landing a sharp one-two combination and a solid left hook. 
• The Ground War: Within the first minute, Gamrot initiated a takedown to bring the fight into his preferred wrestling realm. However, Oliveira instantly engaged his legendary Jiu-Jitsu guard. “Do Bronx” threatened with an armbar and a slick omo plata attempt. While Gamrot defended and escaped the submissions nicely, Oliveira’s fluid transitions allowed him to sweep, take Gamrot’s back, and finish the round in a dominant top position. 

• Aggressive Pressure: Oliveira opened the second frame with complete disregard for Gamrot’s punching power, marching forward recklessly to trade shots and land heavy strikes. 

• The Takedown: Shifting strategies, Oliveira initiated his own body lock takedown, lifting Gamrot entirely into the air and bulldozing him to the canvas. 
• The Submission: Once on the ground, Oliveira was multiple steps ahead. He smoothly transitioned to the back and secured both hooks. He locked in a tight rear-naked choke over Gamrot’s mouth.
