Nacho Beristain, trainer of former four division world champion Juan Manuel Marquez, is giving Manny Pacquiao a 45% chance of defeating unbeaten Floyd Mayweather Jr. on May 2nd at the MGM Grand in Las Vegas.

Nacho sees Mayweather as a the favorite to win, because of his style. He doesn't view Pacquiao as being as big of an underdog as others do.

"I've always liked Pacquiao's style better. Because he has a commercial style, people will gladly pay to see him fight, and the other, as we know, has a defensive style, but also has many resources," Nacho said to ESPN Desportes. "I think Pacquiao has a 45 percent chance. Mayweather is the favorite [but only by a little bit]."

"On paper it is Mayweather who arrives at a better time, because of the knockout Pacquiao suffered to Juan Manuel. But Pacquiao has many things going for him...speed, and being a smart fighter...although people think otherwise, he knows when to shoot his combinations."
