Mares. Style is going to bother Rigo. Imo Mares could take it by points by brawling and staying close to him or box him like he did against Ponce good and smart and could possibly be a ko. He's not going to be like Donaire looking for that one punch ko. If it's going to happen it will happen in featherweight or as a catch weight. Mares already said he's going to stay as a featherweight due to struggling the weight as a bantamweight.
