Tentatively sticking with what I've said from the start and going with a Donaire stoppage.
All down to whether or not Nonito manages to get back on form and fight the right fight though, because in my opinion he's a far better fighter than Nishioka at his best(well maybe not ''far'' superior, but an adjective which suggests he's clearly better but not by too sizable a margin :blood). It's evident that as a result of the Montiel bout he's really fallen in love with his power, so I hope the Mathebula scare was a wake-up call for him. Then again I think Nishioka's style is a lot less troublesome for him than the Mongoose's was.
