At #5 in the women's bantamweight rankings, Ailin Perez — "Fiona" to fight fans — is past the "prospect" stage. This is contender territory, and every fight from here is a title eliminator in disguise.
The game is built on grappling: 4.9 takedowns per 15 minutes, and opponents spend rounds defending instead of fighting. 2 submission wins say what happens when the defense slips.
He arrives on a 5-fight win streak — most recently Macy Chiasson, Decision - Unanimous. Streaks like that don't stay unnoticed for long.
