Win Methods
Kaleio Romero, better known as "KO", brings a 6-2 record into every walk to the cage — and in a division as crowded as featherweight, every single win matters.
The ground is where fights end: 3 wins by submission (50% of the total). Scrambles that look even suddenly aren't.
He's coming off a loss to Dennis Buzukja. Careers aren't defined by the fall, though; they're defined by the rebound.
