From the opening bell, 'The Phenom' displayed the aggressive mentality that runs in his bloodline, immediately closing distance and unleashing crisp combinations before seamlessly transitioning to his grappling arsenal.

The youngest member of the legendary Lee fighting dynasty nearly ended the contest in the first round, dragging Mammarella to the canvas and threatening with a modified kimura that had his opponent in serious danger as the buzzer sounded.

Adrian Lee's relentless pressure continued into the second frame, where his superior grappling skills proved decisive against the determined Italian.

The Prodigy Training Center representative methodically worked his way to Mammarella's back before locking in a picture-perfect rear-naked choke that forced the tap at 1:56 of round two.
