The Kansas born Ortiz plans to become the first man to beat Floyd, the showdown against Mayweather Jnr marks the long and tough journey back to the top for Ortiz.
Two years ago the Kansas born fighter had the world at his feet and, with his explosive fighting style, was being dubbed boxing's new Oscar De La Hoya.
But the 24-year-old's rise to in Boxing was stopped short when he lost to Argentine opponent Marcos Maidana in June 2009 after being stopped in sixth round.
After taking five months off from the sport, Ortiz began his comeback notching up four wins and a draw between December 2009 and December 2010.
On April 16 this year he beat WBC welterweight champion Andre Berto in an epic battle in Conneticut to earn a showdown with Mayweather Jnr.
While he knows that he have to be at his best against the best pound-for pound boxer in the world, Ortiz is determined to finally fulfil his potential he had shown earlier in his career.
"I'm a slumdog, right? I'm a stray," he said. "I'm not supposed to be anywhere near a stage like this,"
"But I refuse to believe that. I've made up my mind that I'm going to be one of the all-time greats and that's where it's at."
