Prediction.

Benn has a good over hand right, Vargas will be prepared for that, but Benn has good variety, a good jab, and good footwork. Vargas is more experienced, but Benn showed vast improvement in his last fight, I think Vargas is a step down from Formella, he's offensively better, but he's a lot easier to get to, I don't think he can work around Benn's jab, he'll try to counter as Benn is first with the jab, but Benn is a combination puncher, it will be hard for Vargas to get his shots off.

I think Benn will out box Vargas for 3 or 4 rounds, will establish his jab, throw varied combinations to head and body, Vargas will struggle with Benn's positioning, his shots will go over his head, and he'll struggle with Benn's movement. I think Vargas will go out on his shield in the mid rounds, I could see him putting Benn on the ropes, and putting him under pressure, but Vargas will miss most of what he throws, and when he relents, steps back, Benn will turn him on the ropes, and tee off with a hard, fast, varied combination, and once Vargas is hurt, I don't think he'll last much longer, because Benn is a good finisher, mixes the attack to head and body, positions his shots, has fast feet, is explosive.

I think Benn stops Vargas in the mid rounds.
