Mandatory challenger Robert "The Ghost" Guerrero (31-1-1, 18KOs) feels stronger than ever as he trains in Las Vegas for his anticipated fight with WBC welterweight champion Floyd Mayweather Jr. (43-0, 26KOs). The Showtime Pay-Per-View main eventg is going to happen on May 4th at the MGM Grand.

Last year, Guerrero moved up by two divisions, from 135 to 147, and won a convincing decision over hard puncher Selcuk Aydin. After passing that test, he returned a few months later to beat down Andre Berto for another impressive victory. Mayweather will be the third and by far the most thoughest test at the weight.

"I’ve just wrapped up my few days of training. I’m in tremendous shape and I’m feeling stronger than ever. This will be my third fight at welterweight so my body has filled in perfectly with the weight hike. A big reason for this is my manager Bob Santos, who has been doing my diet since I was a 16 year old amateur," Guerrero wrote in his Yahoo Sports Blog.

"Bob works extremely hard to make sure I’m eating all the right foods and he really gets it — he knows what my body needs to be at peak performance, so you can expect to see a well-oiled machine on fight night."
