The youngest member of the famous Lee family has finally arrived under the world's largest martial arts organization after his dominant debut against Antonio Mammarella during their lightweight MMA battle at ONE 167 this past weekend inside the Impact Arena in Bangkok, Thailand.
Because of this stellar professional fight, Adrian's older brother, Christian, who currently reigns as the ONE lightweight MMA world champion and ONE welterweight MMA world champion, was incredibly happy for him.
He even posted a few snaps of the fights and captioned it with:
"So incredibly proud of my bro! #THEPHENOM gets it done Rd. 2 via Rear Naked Choke!"

Adrian was literally rag-dolling his Australian opponent, taking the fight wherever it went. In the stand-up affair, 'The Phenom' was piecing up Mamarella with combinations. Meanwhile, in the grappling department, he was taking him down the mat with relative ease.
The 18-year-old prospect even attempted a D-Arce choke, an inverted triangle choke, and a Kimura submission in the opening round, but the MMAFFT athlete survived the onslaught in the first five minutes.
Despite the toughness of Mammarella, Adrian's relentless attack was too much for him to handle, as he was forced to finally tap in the second round via a Rear-naked choke at the 1:56 mark.

Following his stacked amateur career and a dream debut in his maiden professional bout, Adrian is looking to replicate the success of his older siblings, Christian and Angela, who both captured 26-pound golden belts in ONE Championship.
Angela was the former undisputed ONE atomweight MMA world champion before officially retiring in September 2023 during a special appearance at the ONE Fight Night 14 card inside the Singapore Indoor Stadium.
