Win Methods
René Santiago brings a 16-4 record into every walk to the cage — and in a division as crowded as light flyweight, every single win matters.
The record splits almost evenly between stoppages (9) and decisions (7) — a boxer who can hurt you but doesn't need to in order to beat you.
The form line is loud: 4 straight wins, the latest over Masataka Taniguchi (Decision (Unanimous)). Momentum like that forces the division's hand.
