MANILA, Philippines – Interim welterweight champion Robert “The Ghost” Guerrero has moved his training camp to Las Vegas as he gears up for his fight against unbeaten American superstar Floyd Mayweather Jr. on May 4.

In a Boxing Scene report, Guerrero said “Las Vegas is my home now.”

“These next six weeks of training will be very grueling, but I’m well prepared to make the sufficient sacrifices that will be needed to dethrone Mayweather,” he said.

Guerrero (31-1-1, 18 KOs) is facing the toughest challenge of his career in Mayweather, who has not lost in 42 professional fights.

But “The Ghost” is convinced he will be the first man to inflict a loss on the American boxer.

“Believe me, Floyd is in trouble, and there is nothing he can do to escape the punishment I’m going to give him,” Guerrero said.

“God has put me in this position for a reason, and May 4th can come soon enough,” he added.

The first day of his Las Vegas camp went well, he said.

“My body is filling out perfectly. I’m feeling extremely strong right now. I will have all my bases covered for this fight, and I’m leaving no stone unturned,” said Guerrero.
