Between them the two men have 32KO's from 48 bouts and neither has been stopped.
With the bout taking place in Mexico it's fair to assume that Sanchez will be the favourite. World ranked by all 4 of the major organisations Sanchez is ranked as highly as #3 (by the WBA) and as low as #13 (by the WBC) suggesting that we are talking about a genuine world level fighter and one who is really just waiting for a world title bout.
As well as the world rankings Sanchez has genuine talent. He's unbeaten since 2010, when he lost to Mario Macias by 8 round split decision, and since then he has strung together 13 straight wins with 10 coming by stoppage. On paper that's great especially when you consider he blasted out former WBA Flyweight title champion Jean Piero Perez inside a round. Although powerful Sanchez has struggled in bouts where his power hasn't been enough. Not only with the loss to Macias, who Koki Kameda stopped in 4 rounds, but also in close decisions over Jose Carlos Vargas and Marlon Tapales.
Sanchez seems to be a fighter who's a bit of a bully. If his power effects you then you're unlikely to be able to beat him. Skills wise however, he's nothing spectacular and with out trying to sound harsh he's a long way from a world class "boxer".
Going in to this bout Sanchez isn't the only man with limited boxing. Demecillo, a Filipino who has held both the PBF and GAB versions of the Super Flyweight title, was out boxed in his sole loss, a bout that saw him clearly out pointed by the very talented Arthur Villanueva. Aside from that loss, and a very early career technical draw with Marvin Mabait, Demecillo has a perfect record.
Demecillo's strength is his power game. If he hurts you he tends to know he's hurt you and has power to both the head and body. In fact it's the body shots of Demecillo that seem to be the key part of his arsenal with them being use to grind down his foes. Unfortunately despite a nice array of punches Demecillo does often look quite basic and even a little bit predictable. Powerful but predictable.
One of the problems for Demecillo going in to this bout is that he'll be fighting away from the Philippines for the first time. Whilst he has been spending time in Japan recently, and will be in shape, he's never had a fight away from his homeland which can often a big issue. More over is the fact he's actually traveling to Sanchez's home town. Whilst Hermosillo, Sonora wasn't too harsh for Marlon Tapales, who was controversially out pointed by Sanchez, it may be too fat too soon for Demecillo.
We do tend to feel that Sanchez is the more likely to win. Fighting at home with friends and family around him he will be cheered to the rafters and given the close rounds. Though with Demecillo's power and the fact he was a late call up we refuse to suggest that the Filipino has no chance and with that in mind we're actually going to call the upset with Sanchez walking on to a bomb and not recovering in what turns out to be the "sleeper" of the weekend.
