Guerrero tried to pressure Mayweather, but Mayweather had none of it. Guerrero had some success pinning Mayweather in the corner in the first two rounds, but after that, Mayweather used his lateral movement and a laser accurate right hand to pummel Guerrero.
He landed more than 60 percent of his power punches and was never in danger. Only Guerrero's solid chin kept him from being stopped. He repeatedly took clean, hard shots from Mayweather.
