Claudio Puelles

Nobody hands you anything at lightweight. Claudio Puelles — "Prince of Peru" to fight fans — has built a 13-5 record the hard way, one fight at a time since leaving Peru's regional scene.

The game is built on grappling: 3.3 takedowns per 15 minutes, and opponents spend rounds defending instead of fighting. 7 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 Joaquim Silva. Careers aren't defined by the fall, though; they're defined by the rebound.
