I love Vazquez but he was far too hittable and that is a bad thing against Donaire. I've got Donaire by KO with Vazquez going out swinging like he always did.
Donaire KO. Too much movement, speed and boxing ability. I think the one shot KO is also more viable for Nonito. Vazquez would have to take damage to make it competitive and that's rough vs. Donaire
A competitive well fought battle however long it lasts until Donaires sharp counters and deadly counter left hook takes a toll on the Mexican warrior. Donaire likely wins by stoppage.
