INGLEWOOD, California – First-time world title challenger Gabriela Fundora demonstrated she was more than ready to prove her promise, dominating four-time champion Arely Mucino en route to a fifth-round stoppage victory to claim the IBF flyweight crown. 

The 21-year-old Fundora dropped and badly hurt Mucino twice in the fifth, prompting Mucino’s corner to throw in the towel at the 1:18 mark of the round.
