Juancamilo Ronderos

Nobody hands you anything at flyweight. Juancamilo Ronderos — "100" to fight fans — has built a 4-2 record the hard way, one fight at a time since leaving Colombia's regional scene.

The game is built on grappling: 2.7 takedowns per 15 minutes, and opponents spend rounds defending instead of fighting. 2 submission wins say what happens when the defense slips. Add the southpaw stance, and the puzzle gets harder still.

He's coming off a loss to Clayton Carpenter. Careers aren't defined by the fall, though; they're defined by the rebound.
