Cynthia Calvillo

Cynthia Calvillo is part of the UFC women's flyweight division's deep end, fighting out of the United States — 16 pro fights in, still swinging for a number next to his name.

He fights at a pace most of the division can't hold — 4.41 strikes landed a minute, every minute. By round three, opponents are usually fighting his fight.

The last fight went to Loopy Godínez (Decision - Split) — a setback, and the interesting question is always what a fighter does with one.

He's 39 now. Fighters at this stage aren't building toward something; they're spending what's left, and that usually makes for the best fights.
