Three years ago, Kade Ruotolo announced his arrival in ONE Championship in truly spectacular fashion.
The American prodigy didn't ease into his promotional debut, instead stepping inside the Circle against none other than mixed martial arts veteran and tap-out savant Shinya Aoki in a lightweight submission grappling contest at ONE 157, held at the Singapore Indoor Stadium in May 2022.
From the opening bell, Ruotolo came out firing. He pushed the pace, driving the former ONE lightweight MMA world champion backward as he relentlessly hunted for takedowns and transitions.
In one jaw-dropping moment, Ruotolo launched himself off the cage fence to take Aoki's back — an instant highlight.
