The Filipino 22 year old made his name with an upset and will be looking to avoid a similar fate here.
Going in to this bout Duno has been priced as an unbackable 1/20 favourite, making the bout the bout look like a foregone conclusion. That's despite the fact that "El Flaco" Gonzalez is more than 7 years removed from his last stoppage loss, and his last 2 losses have come to world title challengers, Ricardo Dominguez and Mercito Gesta. It's clear that Duno should be the favourite but he's up against a hard hitting, tough and experienced fighter who has won 2 of his previous 3 bouts in the US and dropped Gesta last time out.
For those who are perhaps a little bit tempted on the Mexican he has been priced as a large under-dog at 9/1. He is rightfully the under-dog, but at that price is certainly more interesting than backing Duno.
Sadly the "To Win" market is the only one currently available for this bout.
